Tax Refund Companies and Their Fees: What 36% Actually Costs You

Refund companies occupy a strange position in UK tax. They are entirely legitimate businesses performing a real service, and they are also charging a percentage of money HMRC would hand over in full, for free, to anyone who asked. Both of those things are true at once, which is why the sensible question is not "are they a scam" but "is the convenience worth the price for my claim".

This guide sets out the published fees, what changed in 2023 and what you got back from it, and how to do the same claim yourself. It relies on figures the firms publish themselves and on HMRC's own announcements.

What you are actually buying

Strip out the marketing and the service is: someone gathers your details, identifies which reliefs apply, submits the claim, and chases HMRC. For a straightforward PAYE claim that is perhaps an hour of work, most of which is you assembling paperwork you would have to assemble anyway.

Where it is genuinely worth something is at the messy end. Several years of scattered employers, a CIS claim that needs a Self Assessment return filed alongside it, mileage records across dozens of temporary sites, or simply a person who will not otherwise do it at all. A claim made for a fee beats a claim never made.

Where it is worth much less is the ordinary case: one employer, a wrong tax code, a uniform allowance. Those are ten-minute jobs on HMRC's own service.

The published fee, and what it does to real refunds

RIFT, one of the larger UK operators, publishes its pricing openly, which is more than can be said for parts of the sector. For a PAYE rebate the stated fee is "36% of your refund (including VAT), with a minimum fee of £60". For a CIS claim that includes filing a tax return, RIFT publishes a fixed fee of £354 including VAT. RIFT also notes that VAT "is applied to our fee only, not to your whole refund".

Applied to refund sizes people actually receive:

Note the top row. On small claims a minimum fee is a larger proportion than the headline percentage, and small claims are exactly what a uniform or working from home relief produces. A five-year uniform tax rebate at the standard £60 flat rate is worth around £60 in tax to a basic rate taxpayer, which a £60 minimum fee absorbs entirely.

Other firms publish different rates, and some publish none until you are some way into the process. The RIFT figures are used here because they are stated plainly on the company's own site and are straightforward to verify.

What went wrong before 2023, and what changed

The sector attracted sustained criticism, most prominently from the Low Incomes Tax Reform Group, a charity-backed body that campaigns on tax for people on low incomes. LITRG raised concerns including high fees, overinflated promises, unclear or hidden terms, difficulty contacting firms afterwards, and deeds of assignment that customers did not realise they had signed.

The assignment was the sharp end. An assignment transferred the legal right to a repayment to the company, so HMRC paid the company rather than the taxpayer. LITRG documented cases where refunds entirely unconnected to the original claim were diverted as a result, because the assignment was not limited to the claim it was signed for.

HMRC acted. In its 11 January 2023 announcement on repayment agents, it set out a package that:

• replaced legally binding assignments with cancellable nominations
• introduced a 14 day cooling-off period
• created a registration process for repayment agents
• required agent communications to be "fair, clear, accurate and do not mislead or conceal material facts"

And the legislation followed: assignments of income tax repayments made on or after 15 March 2023 are void, meaning HMRC treats them as having no effect.

Three practical consequences for you

1. You can change your mind. A nomination is cancellable, and there is a cooling-off period. If you signed up in a moment of optimism and have since read HMRC's own guidance, you are not locked in the way you would have been before 2023.

2. Check where a pending refund is going. If you used a firm years ago, an older arrangement may still be routing repayments away from you. This is worth checking before you make any new claim, because a repayment you triggered yourself can still land somewhere else. If something looks wrong, contact HMRC.

3. "Only we can do this" is not true. Every claim route is open to you directly. If a firm tells you a claim can only be made through them, or that HMRC will not deal with you personally, that is not correct.

The free routes, in one place

Everything a refund company would do on your behalf has a free HMRC equivalent.

Our guide to claiming a tax refund from HMRC walks each of those routes, and the full reclaim guide covers a four-year recovery end to end.

How to decide, honestly

Ask three questions.

How big is the claim? Below about £200 a percentage fee with a minimum attached takes a punishing share. Above £1,000, 36% is a substantial sum to pay for an hour of admin.

How complicated is it? One employer and a wrong code is simple. Nine agency placements across three tax years with mileage is not. Complexity is what you might reasonably pay for.

Would you actually do it? This is the honest one. A claim you never make is worth nothing at all, and 64% of something beats 100% of nothing. If paying a fee is what gets it done, that is a defensible choice made with the numbers in front of you.

The only bad version is the one where nobody told you the price.

Start by finding out what you are owed

Before deciding who claims, work out whether there is anything to claim. Our free tax code checker estimates what your code should be for your circumstances across every year still open, and what any gap is worth. No fee, no percentage, and the number is yours to take wherever you like.
