1Summary
A research credit claim is one of many settings in which an adviser helps a person or business claim money from a public scheme, and is sometimes paid a share of what is recovered. This paper looks at three other claims markets in which lawmakers or regulators have acted on fees calculated that way: claims management in the United Kingdom, the employee retention credit in the United States, and the disability tax credit in Canada. It also describes the limits that federal law already places on contingent fees for Social Security, veterans' benefits and federal tort claims.
The tools differ. The UK regulator capped fees as a percentage of redress with a cash maximum in each band.1Source 1Financial Conduct Authority, FCA Handbook, Claims Management: Conduct of Business sourcebook (CMCOB) 5.2, Fee cap for FS claims management agreements, rules CMCOB 5.2.1R, 5.2.9R, 5.2.10R and 5.2.17R (in force 1 March 2022). https://www.handbook.fca.org.uk/handbook/CMCOB/5/2.html (accessed 11 October 2026). Canada replaced percentage fees with a flat maximum of $100 for each request.2Source 2Disability Tax Credit Promoters Restrictions Act, S.C. 2014, c. 7, sections 2 to 7 and 12 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/acts/D-2.8/FullText.html (accessed 11 October 2026).3Source 3Disability Tax Credit Promoters Restrictions Regulations, SOR/2021-55, sections 1 to 3 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/regulations/SOR-2021-55/FullText.html (accessed 11 October 2026). Congress, in 2025, used a fee based on the amount of the refund or credit as part of the test for who counts as an employee retention credit promoter, and attached a due diligence penalty.4Source 4Public Law 119-21, 139 Stat. 72 (4 July 2025), section 70605, Enforcement provisions with respect to COVID-related employee retention credits, subsections (a) to (g), 139 Stat. 286 to 288. https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm (accessed 11 October 2026). Older federal statutes cap the fee, require agency approval or bar any fee before an initial decision.5Source 5Office of the Law Revision Counsel, 42 U.S.C. 406, Representation of claimants before Commissioner, subsection (a)(2)(A), (a)(4) and (a)(5), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title42/html/USCODE-2024-title42-chap7-subchapII-sec406.htm (accessed 11 October 2026).6Source 6Office of the Law Revision Counsel, 38 U.S.C. 5904, Recognition of agents and attorneys generally, subsections (c)(1) to (c)(3) and (d)(1) and (2), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title38/html/USCODE-2024-title38-partIV-chap59-sec5904.htm (accessed 11 October 2026).7Source 7Office of the Law Revision Counsel, 28 U.S.C. 2678, Attorney fees; penalty, United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title28/html/USCODE-2024-title28-partVI-chap171-sec2678.htm (accessed 11 October 2026).
The paper does not claim that any of these markets is the same as the research credit market, and it does not measure outcomes, because no official source found for this paper evaluates them against research credit claims. It describes what each government did and the reasons it gave. Swanson Reed's position on the federal research credit is stated once, in a labeled box.
2Why look at other claims markets
2.1What the markets have in common
In each market described here, three parties are involved: a person or business entitled to money from a public scheme, the government body or regulated firm that pays it, and an adviser who helps make the claim. In each, some advisers have charged a fee calculated as a share of the money recovered.
The federal research credit shares both features. A business claims the credit on its return or on a claim for refund, and IRS examiner guidance has described research credit refund claims as usually based on a study prepared by an outside consultant.8Source 8Internal Revenue Service, Large and Mid Size Business Division, Research Credit Claims Audit Techniques Guide (RCCATG): Credit for Increasing Research Activities Section 41, LMSB-04-0508-030 (May 2008), introductory note and Chapter II "The RC Claim Engagement Letter"; and Internal Revenue Service, Instructions for Form 6765 (Rev. December 2025), which do not ask how a claim preparer was paid. https://www.irs.gov/businesses/research-credit-claims-audit-techniques-guide-rccatg-credit-for-increasing-research-activities-section-41 and https://www.irs.gov/instructions/i6765 (accessed 11 October 2026). Some advisers are paid a contingent fee, which Treasury's rules define to include a fee "based on a percentage of the refund reported on a return" or "of the taxes saved".9Source 9Treasury Department, Circular No. 230, 31 CFR 10.27, Fees, paragraphs (b) and (c). https://www.ecfr.gov/current/title-31/subtitle-A/part-10/subpart-B/section-10.27 (accessed 11 October 2026).
2.2Where the analogy stops
The differences matter as much as the similarities. The UK and Canadian schemes described below pay individuals, mostly consumers or people with disabilities and their families, and their regulators framed their concerns around those claimants.10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026).11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026). The research credit is claimed by businesses, which may be better placed than individual consumers to compare advisers and negotiate terms.
The second difference is who decides the amount. In a UK financial services complaint, a firm, an ombudsman or a compensation scheme decides the redress.10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). In a Social Security or veterans' claim, the agency decides the past-due benefits before any fee is paid from them.5Source 5Office of the Law Revision Counsel, 42 U.S.C. 406, Representation of claimants before Commissioner, subsection (a)(2)(A), (a)(4) and (a)(5), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title42/html/USCODE-2024-title42-chap7-subchapII-sec406.htm (accessed 11 October 2026).6Source 6Office of the Law Revision Counsel, 38 U.S.C. 5904, Recognition of agents and attorneys generally, subsections (c)(1) to (c)(3) and (d)(1) and (2), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title38/html/USCODE-2024-title38-partIV-chap59-sec5904.htm (accessed 11 October 2026). The research credit is self-assessed: the amount on the return is the amount the taxpayer and its adviser calculate, and the IRS asks for the underlying detail if a claim is selected for examination.12Source 12Internal Revenue Service, Research credit claims (Section 41) on amended returns frequently asked questions, introduction and questions 4 and 21 (page last reviewed or updated 1 October 2026). https://www.irs.gov/businesses/corporations/research-credit-claims-section-41-on-amended-returns-frequently-asked-questions (accessed 11 October 2026). Treasury has cited that feature, the possibility of positions that "exploit the audit selection process", as a reason for restricting contingent fees on returns.13Source 13Treasury Department and Internal Revenue Service, Regulations Governing Practice Before the Internal Revenue Service, final regulations, T.D. 9359, 72 FR 54540 (26 September 2007), preamble, "Contingent Fees", pages 54541 to 54542. https://www.federalregister.gov/documents/2007/09/26/E7-18918/regulations-governing-practice-before-the-internal-revenue-service (accessed 11 October 2026). The comparisons below should be read with that difference in mind.
3The United Kingdom: claims management fee caps
3.1Regulation and the statutory duty
Claims management companies help consumers bring complaints and claims, including claims for redress from financial services firms. The Financial Conduct Authority (FCA) took over their regulation in April 2019.14Source 14Financial Conduct Authority, FCA launches claims management companies fees cap, press release, 1 March 2022. https://www.fca.org.uk/news/press-releases/fca-launches-claims-management-companies-fees-cap (accessed 11 October 2026). The FCA explains that when Parliament legislated in 2018 to transfer that regulation, it gave the FCA a statutory duty under the Financial Guidance and Claims Act 2018 to make rules about the fees charged on claims about financial products and services "with a view to securing an appropriate degree of protection from excessive fees".10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026).
The FCA consulted in January 2021 and published its final rules in Policy Statement PS21/18 in November 2021.10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). The rules apply to claims under contracts entered into from 1 March 2022.14Source 14Financial Conduct Authority, FCA launches claims management companies fees cap, press release, 1 March 2022. https://www.fca.org.uk/news/press-releases/fca-launches-claims-management-companies-fees-cap (accessed 11 October 2026).
3.2The cap
The cap applies to fees charged on most claims for monetary redress from a financial services firm, whether the redress is paid directly by the firm, through the Financial Ombudsman Service or through the Financial Services Compensation Scheme.14Source 14Financial Conduct Authority, FCA launches claims management companies fees cap, press release, 1 March 2022. https://www.fca.org.uk/news/press-releases/fca-launches-claims-management-companies-fees-cap (accessed 11 October 2026).10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). Claims about payment protection insurance are outside it, because, in the FCA's words, they are "already subject to a 20% cap, set by Parliament".14Source 14Financial Conduct Authority, FCA launches claims management companies fees cap, press release, 1 March 2022. https://www.fca.org.uk/news/press-releases/fca-launches-claims-management-companies-fees-cap (accessed 11 October 2026).
The cap for a claim is the lower of a maximum percentage of the redress and a maximum total charge, set by band.1Source 1Financial Conduct Authority, FCA Handbook, Claims Management: Conduct of Business sourcebook (CMCOB) 5.2, Fee cap for FS claims management agreements, rules CMCOB 5.2.1R, 5.2.9R, 5.2.10R and 5.2.17R (in force 1 March 2022). https://www.handbook.fca.org.uk/handbook/CMCOB/5/2.html (accessed 11 October 2026).

The total charge includes expenses and any other charge under the agreement, and excludes VAT.1Source 1Financial Conduct Authority, FCA Handbook, Claims Management: Conduct of Business sourcebook (CMCOB) 5.2, Fee cap for FS claims management agreements, rules CMCOB 5.2.1R, 5.2.9R, 5.2.10R and 5.2.17R (in force 1 March 2022). https://www.handbook.fca.org.uk/handbook/CMCOB/5/2.html (accessed 11 October 2026). Where a financial services claim falls outside the cap, a firm must not impose charges that exceed, or are capable of exceeding, an amount that is reasonable in light of the work it has done or will do.1Source 1Financial Conduct Authority, FCA Handbook, Claims Management: Conduct of Business sourcebook (CMCOB) 5.2, Fee cap for FS claims management agreements, rules CMCOB 5.2.1R, 5.2.9R, 5.2.10R and 5.2.17R (in force 1 March 2022). https://www.handbook.fca.org.uk/handbook/CMCOB/5/2.html (accessed 11 October 2026). The FCA also strengthened the information firms must give before a contract, including how fees are calculated and the free routes to redress.14Source 14Financial Conduct Authority, FCA launches claims management companies fees cap, press release, 1 March 2022. https://www.fca.org.uk/news/press-releases/fca-launches-claims-management-companies-fees-cap (accessed 11 October 2026).
3.4Why the FCA chose a cap
The FCA set out its reasoning in PS21/18. It said that a consumer survey it had commissioned suggested that market failures meant customers "could not effectively judge the value of services" that claims management firms provide, "and so they were vulnerable to excessive charges".10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). It defined an excessive charge as one that exceeds the value provided to the individual customer, and said it "found that fees were excessive by this measure and that excessiveness was most pronounced where the amounts of redress were highest".10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026).
The FCA tied that view to the design of the redress system. It said the ethos of that system "is that consumers should be able to make claims for free and should not need any representation".10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). It considered other remedies, including disclosure rules and requiring different charging models, and decided "that imposing a fee cap was the most effective way" to meet its statutory duty.10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). It assessed 13 different specifications of a banded cap, as well as product-specific caps set as a percentage of redress, a fixed amount or a combination of both.10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026).
The FCA also recorded what it expected the cap to change in practice. It said the cap could encourage firms "to have greater regard to the merits of the claims they take on" and to compete more on price and quality of service.10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). It estimated consumer benefits of around £9.6 million a year.14Source 14Financial Conduct Authority, FCA launches claims management companies fees cap, press release, 1 March 2022. https://www.fca.org.uk/news/press-releases/fca-launches-claims-management-companies-fees-cap (accessed 11 October 2026). That figure is the FCA's estimate at the time of the rules, not a measured result.
3.5The arguments the FCA heard against a cap
The FCA reported that feedback on the cap was mixed, with a roughly even split between respondents who agreed with it and respondents who said it was too restrictive.10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). Some respondents said fees were not excessive and that consumers using a firm on a no win no fee basis "will only pay a fee if they receive redress so they can never be out-of-pocket".10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). Others said the cap did not allow for the role of claims firms in "providing access to justice, particularly for vulnerable consumers", and that capped fees could reduce redress for some consumers by discouraging further work beyond a certain point.10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026).
Those are the same arguments made for success fees in research credit work: access, no cost unless something is recovered, and an incentive to pursue the full amount. The FCA did not reject the value of claims firms. It said it wanted them to remain available and viable, and to keep "helping raise awareness of the opportunity to claim and acting as an additional check and balance on the redress system".10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). It concluded that those benefits did not justify fees above the level its cap allows.
3.6What the UK cap is and is not
The UK cap limits a percentage fee. It does not prohibit one. Within each band, a firm may still charge a share of the redress up to the percentage and the cash maximum.1Source 1Financial Conduct Authority, FCA Handbook, Claims Management: Conduct of Business sourcebook (CMCOB) 5.2, Fee cap for FS claims management agreements, rules CMCOB 5.2.1R, 5.2.9R, 5.2.10R and 5.2.17R (in force 1 March 2022). https://www.handbook.fca.org.uk/handbook/CMCOB/5/2.html (accessed 11 October 2026). It applies to consumers claiming redress, not to businesses claiming tax relief. It is described here as a record of one regulator's reasoning about fees calculated as a share of a recovery, not as a model for research credit regulation.
4The United States: the employee retention credit
4.1What the IRS said about fees
The employee retention credit was a refundable federal credit for employers during the COVID-19 pandemic. It is a different credit from the research credit, with different rules, and nothing in this section is evidence about research credit advisers. It is described because it is the most recent federal experience of a credit market in which percentage fees were common.
In September 2023 the IRS stopped processing new employee retention credit claims. Its announcement said that "a promoter can collect a contingency fee of up to 25% of the ERC refund" and reminded anyone who improperly claimed the credit that "they must pay it back, possibly with penalties and interest".15Source 15Internal Revenue Service, To protect taxpayers from scams, IRS orders immediate stop to new Employee Retention Credit processing amid surge of questionable claims, News release IR-2023-169, 14 September 2023. https://www.irs.gov/newsroom/to-protect-taxpayers-from-scams-irs-orders-immediate-stop-to-new-employee-retention-credit-processing-amid-surge-of-questionable-claims-concerns-from-tax-pros (accessed 11 October 2026). The IRS's current list of warning signs for the credit includes "Fees based on a percentage of the refund amount of Employee Retention Credit claimed", with the advice that "you should always avoid a tax preparer basing their fee on the amount of the refund".16Source 16Internal Revenue Service, Employee Retention Credit, section "Beware of ERC scams" (page last reviewed or updated 8 October 2026). https://www.irs.gov/coronavirus/employee-retention-credit (accessed 11 October 2026).
In December 2023 the IRS opened a voluntary disclosure program that let employers repay 80 percent of the credit they had received. It explained: "The IRS selected an 80% repayment because many of the ERC promoters charged a percentage fee" that they collected at the time of payment or in advance, "and the recipients never received the full amount."17Source 17Internal Revenue Service, IRS new Voluntary Disclosure Program lets employers who received questionable Employee Retention Credits pay them back at discounted rate, News release IR-2023-247, 21 December 2023. https://www.irs.gov/newsroom/irs-new-voluntary-disclosure-program-lets-employers-who-received-questionable-employee-retention-credits-pay-them-back-at-discounted-rate-interested-taxpayers-must-apply-by-march-22 (accessed 11 October 2026). Participants had to give the IRS the names, addresses and telephone numbers of any advisers or preparers who helped them.17Source 17Internal Revenue Service, IRS new Voluntary Disclosure Program lets employers who received questionable Employee Retention Credits pay them back at discounted rate, News release IR-2023-247, 21 December 2023. https://www.irs.gov/newsroom/irs-new-voluntary-disclosure-program-lets-employers-who-received-questionable-employee-retention-credits-pay-them-back-at-discounted-rate-interested-taxpayers-must-apply-by-march-22 (accessed 11 October 2026).
4.2What Congress did in 2025
Public Law 119-21, enacted on 4 July 2025, contains enforcement provisions for the employee retention credit.4Source 4Public Law 119-21, 139 Stat. 72 (4 July 2025), section 70605, Enforcement provisions with respect to COVID-related employee retention credits, subsections (a) to (g), 139 Stat. 286 to 288. https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm (accessed 11 October 2026). They do not ban contingent fees. Instead, they use the fee as part of the definition of who is a "COVID-ERTC promoter".
Under section 70605(b), a person who provides aid, assistance or advice with respect to an employee retention credit document is a promoter if:4Source 4Public Law 119-21, 139 Stat. 72 (4 July 2025), section 70605, Enforcement provisions with respect to COVID-related employee retention credits, subsections (a) to (g), 139 Stat. 286 to 288. https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm (accessed 11 October 2026).
- the person "charges or receives a fee for such aid, assistance, or advice which is based on the amount of the refund or credit", and its gross receipts from such work exceed 20 percent of its gross receipts for the year; or
- regardless of how it charges, its gross receipts from such work exceed 50 percent of its gross receipts, or exceed both 20 percent of its gross receipts and $500,000.
A promoter that fails to comply with due diligence requirements imposed by Treasury in determining eligibility for, or the amount of, the credit is liable to a penalty of $1,000 for each failure.4Source 4Public Law 119-21, 139 Stat. 72 (4 July 2025), section 70605, Enforcement provisions with respect to COVID-related employee retention credits, subsections (a) to (g), 139 Stat. 286 to 288. https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm (accessed 11 October 2026). The statute says those requirements are to be similar to the due diligence requirements under section 6695(g), and the penalty applies only to documents that are, or relate to, a return or claim for refund.4Source 4Public Law 119-21, 139 Stat. 72 (4 July 2025), section 70605, Enforcement provisions with respect to COVID-related employee retention credits, subsections (a) to (g), 139 Stat. 286 to 288. https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm (accessed 11 October 2026).
The same section barred credits or refunds after enactment unless the claim was filed by 31 January 2024, extended the period for assessing amounts attributable to the credit to six years, and extended the penalty for an excessive refund claim under section 6676 from income tax to "income or employment tax".4Source 4Public Law 119-21, 139 Stat. 72 (4 July 2025), section 70605, Enforcement provisions with respect to COVID-related employee retention credits, subsections (a) to (g), 139 Stat. 286 to 288. https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm (accessed 11 October 2026). The section 6676 penalty falls on "the person making such claim", which is the taxpayer.18Source 18Office of the Law Revision Counsel, 26 U.S.C. 6676, Erroneous claim for refund or credit, subsection (a), United States Code 2024 edition published by the Government Publishing Office (before the amendment made by Public Law 119-21, section 70605(f)). https://www.govinfo.gov/content/pkg/USCODE-2024-title26/html/USCODE-2024-title26-subtitleF-chap68-subchapB-partI-sec6676.htm (accessed 11 October 2026).
4.3What the federal approach shows
The 2025 statute is the clearest recent statement by Congress that a fee based on the amount of a refund or credit is a relevant marker of risk in a credit market. It did not cap or prohibit the fee. It used the fee, alongside the share of the adviser's business that came from the credit, to decide who should carry an extra due diligence duty. It did so late in the life of the credit: the same section barred new claims filed after 31 January 2024, and the promoter provisions apply only to aid, assistance and advice provided after the date of enactment.4Source 4Public Law 119-21, 139 Stat. 72 (4 July 2025), section 70605, Enforcement provisions with respect to COVID-related employee retention credits, subsections (a) to (g), 139 Stat. 286 to 288. https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm (accessed 11 October 2026).
5Canada: disability tax credit promoters
5.1The Act
Canada's Disability Tax Credit Promoters Restrictions Act received royal assent on 29 May 2014.2Source 2Disability Tax Credit Promoters Restrictions Act, S.C. 2014, c. 7, sections 2 to 7 and 12 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/acts/D-2.8/FullText.html (accessed 11 October 2026). It defines a promoter as "a person who, directly or indirectly, accepts or charges a fee in respect of a disability tax credit request", and prohibits a promoter from accepting or charging a fee that exceeds the maximum fee set by regulation.2Source 2Disability Tax Credit Promoters Restrictions Act, S.C. 2014, c. 7, sections 2 to 7 and 12 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/acts/D-2.8/FullText.html (accessed 11 October 2026). A promoter who does so is liable to a penalty of $1,000 plus the excess fee, less any part of the fee repaid to the claimant within 120 days after the promoter notifies the Minister.2Source 2Disability Tax Credit Promoters Restrictions Act, S.C. 2014, c. 7, sections 2 to 7 and 12 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/acts/D-2.8/FullText.html (accessed 11 October 2026). Promoters must report fees above the maximum, and charging an excess fee is also an offence punishable by a fine of 100 to 200 percent of the excess.2Source 2Disability Tax Credit Promoters Restrictions Act, S.C. 2014, c. 7, sections 2 to 7 and 12 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/acts/D-2.8/FullText.html (accessed 11 October 2026).
The Act was inoperative until a maximum fee was prescribed.11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026). It came into force on 15 November 2021, together with the regulations.2Source 2Disability Tax Credit Promoters Restrictions Act, S.C. 2014, c. 7, sections 2 to 7 and 12 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/acts/D-2.8/FullText.html (accessed 11 October 2026).3Source 3Disability Tax Credit Promoters Restrictions Regulations, SOR/2021-55, sections 1 to 3 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/regulations/SOR-2021-55/FullText.html (accessed 11 October 2026).
5.2The cap
The regulations set the maximum fee at $100 for a request for a determination of disability tax credit eligibility, and $100 per taxation year for a request relating to the deduction or to any deduction or overpayment that depends on eligibility.3Source 3Disability Tax Credit Promoters Restrictions Regulations, SOR/2021-55, sections 1 to 3 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/regulations/SOR-2021-55/FullText.html (accessed 11 October 2026). If more than one request is made for a claimant for a taxation year, the total fee must not exceed $100.3Source 3Disability Tax Credit Promoters Restrictions Regulations, SOR/2021-55, sections 1 to 3 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/regulations/SOR-2021-55/FullText.html (accessed 11 October 2026). The regulations provide for the maximum to be adjusted for inflation on 1 December 2025 and every fifth year after that, if the adjustment is $5 or more.3Source 3Disability Tax Credit Promoters Restrictions Regulations, SOR/2021-55, sections 1 to 3 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/regulations/SOR-2021-55/FullText.html (accessed 11 October 2026).
The fee restriction does not apply to preparing parts of a tax return that are not disability related, to unrelated tax advice, or to appeals to the Tax Court of Canada.11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026).
5.3Why Canada acted
The regulatory impact analysis published with the regulations states the policy intent of the Act: to limit promoters' fees "to ensure that the income tax refunds generated by tax credits ... remain at the disposal of those who are entitled to them, and who need them most".11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026). It states that persons with disabilities and their families "have been paying what are considered excessive fees to certain promoters", and estimates that promoters collected between $9.5 million and $25.4 million for about 36,000 requests for the 2018 calendar year.11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026).
The analysis also reports the views heard in public consultation in 2014. Participants discussed percentage fees ranging from 1 to 40 percent of the refund. It records that "many participants felt current rates (15% to 40%) are too high", while "others felt current rates are appropriate and the market would regulate itself".11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026). Options discussed included a maximum fee modeled on Canada's tax refund discounting rules, fixed fees, combinations of a fixed fee and a charge for each year reassessed, and maximum hourly rates.11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026). The government chose a flat cap.
5.4How Canada enforces it
The analysis describes the enforcement approach: the disability tax credit certificate was to collect whether a promoter helped with the request, whether a fee was charged and its amount, and a separate form was created for promoters to report excess fees.11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026).
5.5A related Canadian practice: disclosure in SR&ED claims
Canada does not cap fees for its scientific research and experimental development (SR&ED) program, but it does ask about them. The claim form guide asks for each claim preparer's name and business number and the type of billing arrangement, and tells claimants to enter code 1 for "a contingency fee as a percentage of the investment tax credit earned", together with the billing rate and the total fee.19Source 19Canada Revenue Agency, T4088 Guide to Form T661, Scientific Research and Experimental Development (SR&ED) Expenditures Claim (Rev. 20, date modified 18 February 2026), Part 9, lines 935 to 975. https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/t4088/guide-form-t661-scientific-research-experimental-development-expenditures-claim-guide-form-t661.html (accessed 11 October 2026). A penalty of $1,000 may be assessed for each SR&ED claim for which this information is missing, incomplete or inaccurate, and the claim preparer is jointly and severally liable with the claimant for it.19Source 19Canada Revenue Agency, T4088 Guide to Form T661, Scientific Research and Experimental Development (SR&ED) Expenditures Claim (Rev. 20, date modified 18 February 2026), Part 9, lines 935 to 975. https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/t4088/guide-form-t661-scientific-research-experimental-development-expenditures-claim-guide-form-t661.html (accessed 11 October 2026). This is disclosure rather than restriction. It is described in more detail on the Canada contingency fees in SR&ED page.
6Federal precedents in the United States
Federal law has limited contingent fees in claims against the government for decades. Three examples show the range of tools.
6.1Social Security benefits
For a claim to past-due Social Security benefits, the Commissioner approves a written fee agreement only if the fee does not exceed the lesser of 25 percent of the past-due benefits or a dollar amount, and the determination is favorable to the claimant.5Source 5Office of the Law Revision Counsel, 42 U.S.C. 406, Representation of claimants before Commissioner, subsection (a)(2)(A), (a)(4) and (a)(5), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title42/html/USCODE-2024-title42-chap7-subchapII-sec406.htm (accessed 11 October 2026). The statute sets the dollar amount at $4,000 and allows the Commissioner to increase it.5Source 5Office of the Law Revision Counsel, 42 U.S.C. 406, Representation of claimants before Commissioner, subsection (a)(2)(A), (a)(4) and (a)(5), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title42/html/USCODE-2024-title42-chap7-subchapII-sec406.htm (accessed 11 October 2026). The Social Security Administration raised it to $9,200 effective 30 November 2024 and has said that cap remains in effect.20Source 20Social Security Administration, Maximum Dollar Limit in the Fee Agreement Process, 89 FR 40523 (10 May 2024), and Maximum Dollar Limit in the Fee Agreement Process; Partial Rescission, 90 FR 19241 (6 May 2025), summaries. https://www.federalregister.gov/documents/2024/05/10/2024-10248/maximum-dollar-limit-in-the-fee-agreement-process and https://www.federalregister.gov/documents/2025/05/06/2025-07813/maximum-dollar-limit-in-the-fee-agreement-process-partial-rescission (accessed 11 October 2026). For attorneys, the Commissioner pays the fee directly from the past-due benefits, up to 25 percent of them.5Source 5Office of the Law Revision Counsel, 42 U.S.C. 406, Representation of claimants before Commissioner, subsection (a)(2)(A), (a)(4) and (a)(5), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title42/html/USCODE-2024-title42-chap7-subchapII-sec406.htm (accessed 11 October 2026). Knowingly charging or collecting a fee above the maximum is a misdemeanor.5Source 5Office of the Law Revision Counsel, 42 U.S.C. 406, Representation of claimants before Commissioner, subsection (a)(2)(A), (a)(4) and (a)(5), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title42/html/USCODE-2024-title42-chap7-subchapII-sec406.htm (accessed 11 October 2026).
6.2Veterans' benefits
For veterans' benefits, a fee generally "may not be charged, allowed, or paid" for an agent's or attorney's services provided before the claimant is notified of the initial decision on the claim.6Source 6Office of the Law Revision Counsel, 38 U.S.C. 5904, Recognition of agents and attorneys generally, subsections (c)(1) to (c)(3) and (d)(1) and (2), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title38/html/USCODE-2024-title38-partIV-chap59-sec5904.htm (accessed 11 October 2026). After that point, fee agreements must be filed with the Department of Veterans Affairs, which may reduce a fee it finds "excessive or unreasonable".6Source 6Office of the Law Revision Counsel, 38 U.S.C. 5904, Recognition of agents and attorneys generally, subsections (c)(1) to (c)(3) and (d)(1) and (2), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title38/html/USCODE-2024-title38-partIV-chap59-sec5904.htm (accessed 11 October 2026). Where the fee is contingent on a favorable result and paid directly from past-due benefits, it may not exceed 20 percent of those benefits.6Source 6Office of the Law Revision Counsel, 38 U.S.C. 5904, Recognition of agents and attorneys generally, subsections (c)(1) to (c)(3) and (d)(1) and (2), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title38/html/USCODE-2024-title38-partIV-chap59-sec5904.htm (accessed 11 October 2026).
6.3Federal tort claims
Under the Federal Tort Claims Act, an attorney may not charge more than 25 percent of a judgment or litigation settlement, or more than 20 percent of an administrative award, compromise or settlement.7Source 7Office of the Law Revision Counsel, 28 U.S.C. 2678, Attorney fees; penalty, United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title28/html/USCODE-2024-title28-partVI-chap171-sec2678.htm (accessed 11 October 2026). Charging more is punishable by a fine of up to $2,000, imprisonment of up to one year, or both.7Source 7Office of the Law Revision Counsel, 28 U.S.C. 2678, Attorney fees; penalty, United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title28/html/USCODE-2024-title28-partVI-chap171-sec2678.htm (accessed 11 October 2026).
6.4What the precedents share
In each of these federal schemes, Congress accepted contingent fees but limited them. And in each, a government body decides the amount before the fee is calculated: an agency determines the past-due benefits, a court enters the judgment, or the agency makes or agrees the award or settlement.5Source 5Office of the Law Revision Counsel, 42 U.S.C. 406, Representation of claimants before Commissioner, subsection (a)(2)(A), (a)(4) and (a)(5), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title42/html/USCODE-2024-title42-chap7-subchapII-sec406.htm (accessed 11 October 2026).6Source 6Office of the Law Revision Counsel, 38 U.S.C. 5904, Recognition of agents and attorneys generally, subsections (c)(1) to (c)(3) and (d)(1) and (2), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title38/html/USCODE-2024-title38-partIV-chap59-sec5904.htm (accessed 11 October 2026).7Source 7Office of the Law Revision Counsel, 28 U.S.C. 2678, Attorney fees; penalty, United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title28/html/USCODE-2024-title28-partVI-chap171-sec2678.htm (accessed 11 October 2026). The veterans' rule goes further by barring any fee for help with the initial claim.6Source 6Office of the Law Revision Counsel, 38 U.S.C. 5904, Recognition of agents and attorneys generally, subsections (c)(1) to (c)(3) and (d)(1) and (2), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title38/html/USCODE-2024-title38-partIV-chap59-sec5904.htm (accessed 11 October 2026).

8What the comparison shows
8.1Governments have acted on the fee structure itself
In every market described here, the government focused on how the fee was calculated, not on the conduct of any particular adviser. The FCA framed its concern as a market in which customers could not judge value.10Source 10Financial Conduct Authority, PS21/18: Restricting CMC charges for financial products and services claims, Policy Statement (November 2021), paragraphs 1.3, 1.4, 1.9 to 1.13, 2.4 to 2.10 and 2.16 to 2.19. https://www.fca.org.uk/publication/policy/ps21-18.pdf (accessed 11 October 2026). Canada framed its concern as fees that took money intended for people with disabilities.11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026). Congress, in 2025, framed its concern by reference to fees "based on the amount of the refund or credit".4Source 4Public Law 119-21, 139 Stat. 72 (4 July 2025), section 70605, Enforcement provisions with respect to COVID-related employee retention credits, subsections (a) to (g), 139 Stat. 286 to 288. https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm (accessed 11 October 2026). None of these measures depended on a finding that every adviser charging such a fee behaved badly, and this paper makes no such suggestion about research credit advisers.
8.2The tools range from disclosure to prohibition
The tools form a range. Canada's SR&ED rules require disclosure of the fee arrangement.19Source 19Canada Revenue Agency, T4088 Guide to Form T661, Scientific Research and Experimental Development (SR&ED) Expenditures Claim (Rev. 20, date modified 18 February 2026), Part 9, lines 935 to 975. https://www.canada.ca/en/revenue-agency/services/forms-publications/publications/t4088/guide-form-t661-scientific-research-experimental-development-expenditures-claim-guide-form-t661.html (accessed 11 October 2026). The 2025 federal rules attach an extra duty to advisers paid on the amount of the credit.4Source 4Public Law 119-21, 139 Stat. 72 (4 July 2025), section 70605, Enforcement provisions with respect to COVID-related employee retention credits, subsections (a) to (g), 139 Stat. 286 to 288. https://www.govinfo.gov/content/pkg/PLAW-119publ21/html/PLAW-119publ21.htm (accessed 11 October 2026). The UK and Social Security rules cap a percentage.1Source 1Financial Conduct Authority, FCA Handbook, Claims Management: Conduct of Business sourcebook (CMCOB) 5.2, Fee cap for FS claims management agreements, rules CMCOB 5.2.1R, 5.2.9R, 5.2.10R and 5.2.17R (in force 1 March 2022). https://www.handbook.fca.org.uk/handbook/CMCOB/5/2.html (accessed 11 October 2026).5Source 5Office of the Law Revision Counsel, 42 U.S.C. 406, Representation of claimants before Commissioner, subsection (a)(2)(A), (a)(4) and (a)(5), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title42/html/USCODE-2024-title42-chap7-subchapII-sec406.htm (accessed 11 October 2026). Canada's disability tax credit rules replace a percentage with a flat amount.3Source 3Disability Tax Credit Promoters Restrictions Regulations, SOR/2021-55, sections 1 to 3 and note on coming into force (consolidation current to 21 September 2026). https://laws-lois.justice.gc.ca/eng/regulations/SOR-2021-55/FullText.html (accessed 11 October 2026). The veterans' rule bars any fee before the initial decision.6Source 6Office of the Law Revision Counsel, 38 U.S.C. 5904, Recognition of agents and attorneys generally, subsections (c)(1) to (c)(3) and (d)(1) and (2), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title38/html/USCODE-2024-title38-partIV-chap59-sec5904.htm (accessed 11 October 2026). Treasury's own rule for practitioners, in Circular 230, already sits near the prohibition end of that range for returns and refund claims, although courts have limited how far it reaches.9Source 9Treasury Department, Circular No. 230, 31 CFR 10.27, Fees, paragraphs (b) and (c). https://www.ecfr.gov/current/title-31/subtitle-A/part-10/subpart-B/section-10.27 (accessed 11 October 2026).21Source 21US District Court for the District of Columbia, Ridgely v. Lew, Civil Action No. 1:12-cv-00565 (CRC), Memorandum Opinion, 16 July 2014, pages 1 and 14 to 15. https://www.govinfo.gov/content/pkg/USCOURTS-dcd-1_12-cv-00565/pdf/USCOURTS-dcd-1_12-cv-00565-1.pdf (accessed 11 October 2026).
8.3Caps work best where someone else fixes the base
A percentage cap limits the share of the recovery. It does not change the fact that the fee rises with the amount recovered. In the federal precedents, that matters less, because an agency or court decides or agrees the amount before the fee is calculated.5Source 5Office of the Law Revision Counsel, 42 U.S.C. 406, Representation of claimants before Commissioner, subsection (a)(2)(A), (a)(4) and (a)(5), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title42/html/USCODE-2024-title42-chap7-subchapII-sec406.htm (accessed 11 October 2026).6Source 6Office of the Law Revision Counsel, 38 U.S.C. 5904, Recognition of agents and attorneys generally, subsections (c)(1) to (c)(3) and (d)(1) and (2), United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title38/html/USCODE-2024-title38-partIV-chap59-sec5904.htm (accessed 11 October 2026).7Source 7Office of the Law Revision Counsel, 28 U.S.C. 2678, Attorney fees; penalty, United States Code 2024 edition published by the Government Publishing Office. https://www.govinfo.gov/content/pkg/USCODE-2024-title28/html/USCODE-2024-title28-partVI-chap171-sec2678.htm (accessed 11 October 2026). In a self-assessed tax credit, the amount on the return is calculated by the taxpayer and its adviser.8Source 8Internal Revenue Service, Large and Mid Size Business Division, Research Credit Claims Audit Techniques Guide (RCCATG): Credit for Increasing Research Activities Section 41, LMSB-04-0508-030 (May 2008), introductory note and Chapter II "The RC Claim Engagement Letter"; and Internal Revenue Service, Instructions for Form 6765 (Rev. December 2025), which do not ask how a claim preparer was paid. https://www.irs.gov/businesses/research-credit-claims-audit-techniques-guide-rccatg-credit-for-increasing-research-activities-section-41 and https://www.irs.gov/instructions/i6765 (accessed 11 October 2026). A cap would limit the fee on that amount, but the fee would still rise with each judgment that enlarges the claim. That is why Treasury's reasoning in 2007 focused on returns and refund claims, and why it allowed contingent fees once the IRS had begun an examination.13Source 13Treasury Department and Internal Revenue Service, Regulations Governing Practice Before the Internal Revenue Service, final regulations, T.D. 9359, 72 FR 54540 (26 September 2007), preamble, "Contingent Fees", pages 54541 to 54542. https://www.federalregister.gov/documents/2007/09/26/E7-18918/regulations-governing-practice-before-the-internal-revenue-service (accessed 11 October 2026).9Source 9Treasury Department, Circular No. 230, 31 CFR 10.27, Fees, paragraphs (b) and (c). https://www.ecfr.gov/current/title-31/subtitle-A/part-10/subpart-B/section-10.27 (accessed 11 October 2026).
8.4What the comparison does not show
This paper found no official evaluation that compares claim quality before and after any of these measures. The FCA's £9.6 million figure is a forecast of consumer benefit, not a measure of claim accuracy.14Source 14Financial Conduct Authority, FCA launches claims management companies fees cap, press release, 1 March 2022. https://www.fca.org.uk/news/press-releases/fca-launches-claims-management-companies-fees-cap (accessed 11 October 2026). Canada's figures describe fees collected before the cap, not claims allowed or disallowed.11Source 11Government of Canada, Disability Tax Credit Promoters Restrictions Regulations: SOR/2021-55, Regulatory Impact Analysis Statement, Canada Gazette, Part II, Volume 155, Number 8 (14 April 2021), sections "Executive summary", "Issues", "Background", "Description", "Consultation" and "Compliance and enforcement". https://gazette.gc.ca/rp-pr/p2/2021/2021-04-14/html/sor-dors55-eng.html (accessed 11 October 2026). The IRS's 80 percent repayment rate reflects fees already taken from employee retention credit payouts, not a finding about how those claims were prepared.17Source 17Internal Revenue Service, IRS new Voluntary Disclosure Program lets employers who received questionable Employee Retention Credits pay them back at discounted rate, News release IR-2023-247, 21 December 2023. https://www.irs.gov/newsroom/irs-new-voluntary-disclosure-program-lets-employers-who-received-questionable-employee-retention-credits-pay-them-back-at-discounted-rate-interested-taxpayers-must-apply-by-march-22 (accessed 11 October 2026). For the federal research credit, no IRS form records how a claim's preparer was paid, so no comparable data exists.8Source 8Internal Revenue Service, Large and Mid Size Business Division, Research Credit Claims Audit Techniques Guide (RCCATG): Credit for Increasing Research Activities Section 41, LMSB-04-0508-030 (May 2008), introductory note and Chapter II "The RC Claim Engagement Letter"; and Internal Revenue Service, Instructions for Form 6765 (Rev. December 2025), which do not ask how a claim preparer was paid. https://www.irs.gov/businesses/research-credit-claims-audit-techniques-guide-rccatg-credit-for-increasing-research-activities-section-41 and https://www.irs.gov/instructions/i6765 (accessed 11 October 2026).
9What this means for the federal research credit
The other markets show that limiting percentage fees in a claims market is an established policy choice, made by different governments with different tools. They show that the reasons given are consistent: claimants who cannot easily judge value, public money intended for the claimant, and fees that rise with the size of the recovery. They also show that a cap is a compromise suited to schemes where someone other than the adviser fixes the amount.
The research credit is a self-assessed business credit. The adviser's calculation is the amount claimed, and the IRS reviews the detail if a claim is selected for examination.12Source 12Internal Revenue Service, Research credit claims (Section 41) on amended returns frequently asked questions, introduction and questions 4 and 21 (page last reviewed or updated 1 October 2026). https://www.irs.gov/businesses/corporations/research-credit-claims-section-41-on-amended-returns-frequently-asked-questions (accessed 11 October 2026).13Source 13Treasury Department and Internal Revenue Service, Regulations Governing Practice Before the Internal Revenue Service, final regulations, T.D. 9359, 72 FR 54540 (26 September 2007), preamble, "Contingent Fees", pages 54541 to 54542. https://www.federalregister.gov/documents/2007/09/26/E7-18918/regulations-governing-practice-before-the-internal-revenue-service (accessed 11 October 2026). For that reason, the comparison points toward the tools at the stronger end of the range rather than a percentage cap.
Congress should prohibit contingent fees, commonly called success fees, in federal research and development tax credit engagements under Section 41, so that advisers are paid for the work they perform rather than for the size of the claim they produce. Swanson Reed, which publishes this paper, is a fixed-fee R&D tax adviser. It has a direct commercial interest in the outcome: it does not charge success fees, and a ban would remove a pricing model it competes against. This position concerns the federal research credit only. It is not a recommendation about the UK, Canadian or other schemes described in this paper.
