Introduction: Claim of Right Relief Decides Whether a Clawback Costs You Twice
The claim of right doctrine is the reason an American banker in London can repay £180,000 of a bonus and receive nothing at all from the IRS in return. You paid tax on the money when you received it. You then handed most of it back. Nevertheless, the two tax systems disagree about which year the relief belongs in, and one of them may give you no relief whatsoever.
Clawbacks have become routine. Malus and clawback provisions now sit in almost every senior banking contract, and regulators expect them to be enforced. Consequently, a resignation, a risk event or a restatement can trigger a repayment obligation years after the bonus was taxed. Meanwhile, the tax consequences are governed by rules written for entirely different situations.
Furthermore, the published guidance on each side is single-jurisdiction. American articles on the claim of right rules never mention negative taxable earnings, and British articles on bonus clawbacks never mention section 1341. At TaxYork we handle this analysis for banking and fund clients whenever a clawback notice lands. Below, we set out both regimes and show precisely where the relief evaporates.
What the Claim of Right Doctrine Actually Is
The claim of right doctrine came from the Supreme Court in 1932. Where you receive money and treat it as your own without restriction on its use, you must include it in income in that year, even though a dispute might later require you to return it. Therefore, the tax follows the receipt rather than the eventual outcome.
That principle is sensible in isolation. However, it creates an obvious unfairness when the money does go back. Specifically, you were taxed at your marginal rate in a high-earning year, and the repayment falls in a later year when your circumstances may be entirely different.
Why a Clawback Creates Phantom Income
Section 1341 exists to soften that unfairness, and claim of right relief is the only meaningful American route available. Without it, you would have paid tax on income you never ultimately kept. Consequently, practitioners describe the untreated position as a whipsaw, because the taxpayer suffers tax on money that has vanished.
Notably, the relief is not automatic and not always valuable. Additionally, an American living in Britain faces a further complication that domestic taxpayers never encounter, which we come to below.
How Section 1341 Claim of Right Relief Works
The claim of right statute sits in 26 U.S. Code § 1341, and its mechanics reward careful reading.
The Three Statutory Conditions
First, an item must have been included in your gross income in a prior year because it appeared that you had an unrestricted right to it. Second, a deduction must be allowable in the current year because it was established after the close of that prior year that you did not in fact hold an unrestricted right. Third, the amount must exceed $3,000.
All three conditions must hold. Accordingly, the claim of right analysis begins with the contract, because the second condition turns on whether the repayment obligation reverses the original entitlement rather than arising from some separate bargain.
Two Routes, and You Take the Better One
Where the claim of right conditions are met, you compute your tax two ways and use whichever produces the lower liability. Under the first route, you simply deduct the repayment in the year you make it. Under the second, you claim a credit equal to the reduction in the earlier year's tax that would have resulted had the repaid amount never been included.
The credit route is powerful because it restores tax at the rate you actually paid. Therefore, a repayment of income originally taxed at 37% recovers relief at 37%, even if your current marginal rate is far lower.
The Deduction Route Survives the Suspension
Here is a claim of right point that a surprising number of published articles get wrong. The One Big Beautiful Bill Act made permanent the suspension of miscellaneous itemised deductions, and commentators frequently conclude that the section 1341 deduction died with it.
It did not. Section 67(b) lists the deductions that are *not* miscellaneous itemised deductions, and paragraph (9) expressly names the deduction under section 1341. Consequently, the suspension in section 67(h) does not reach it, and the deduction remains available as an other itemised deduction free of any floor.
Repayments of $3,000 or Less Get Nothing
The genuine casualty of the suspension is the small repayment. A repayment of $3,000 or less never qualified for section 1341 and was instead deducted as an ordinary miscellaneous itemised deduction subject to the two per cent floor. Since that category is now permanently disallowed, such a repayment attracts no relief at all.
Therefore, an employee repaying $2,800 is worse off than one repaying $3,100, which is an unattractive cliff edge. Nevertheless, that is the law, and clawback settlements should be sized with the threshold in mind where there is any negotiating room.
How the Credit Is Reported
You recompute the earlier year's tax on a worksheet without filing an amended return, then enter the resulting credit in the other payments and credits section of Schedule 3, identifying it as I.R.C. 1341. IRS Publication 525 sets out the repayment rules and worked examples.
Importantly, you do not amend the original year. Consequently, an amended return is the wrong instrument here, and filing one instead of claiming the credit is a common and costly error.
When a Clawback Qualifies for Claim of Right Relief
Not every repayment attracts relief, and the distinctions are subtle. Three broad categories emerge from the case law and from professional commentary.
Mere Errors
Where a bonus was simply miscalculated and the excess is returned, the position is generally straightforward. The employee never had an unrestricted right to the overpayment, and the claim of right conditions are usually satisfied. Additionally, where the correction happens within the same tax year, payroll can often reverse it and no section 1341 analysis is needed at all.
Bona Fide Disputes and Contractual Reversals
The harder and more common case involves a genuine contractual clawback. Here the employee did have an apparent unrestricted right when the bonus was paid, and a later event triggered repayment. Consequently, the analysis turns on whether the contract reversed the original entitlement or created a fresh obligation.
That distinction matters enormously. Specifically, a provision framed as a repayment of the bonus supports claim of right relief far better than one framed as liquidated damages or as a separate payment obligation. Therefore, we review the clawback wording before advising on the tax position, and we would encourage anyone negotiating a contract to have the wording reviewed then rather than later.
Wrongdoing and the Public Policy Limit
Where the repayment follows fraud or other misconduct, relief becomes doubtful. Courts have been reluctant to allow a deduction that would effectively subsidise the consequences of wrongdoing. Accordingly, a clawback enforced after a finding of misconduct carries real risk that no claim of right relief will be available at all.
The UK Side: Negative Taxable Earnings
Britain reaches a destination broadly similar to the claim of right result by a completely different route, and the leading authority is now well established.
Martin v HMRC
In *Martin v HMRC*, an employee received a £250,000 signing bonus subject to a five-year service condition. He resigned early and repaid £162,500 under the clawback provision. The Upper Tribunal held that the repayment constituted negative taxable earnings under section 11 of ITEPA 2003.
The reasoning matters for anyone relying on it. Specifically, the Tribunal treated a payment from employee to employer that reverses an earlier payment of earnings under the same contract as the clearest example of negative earnings. Consequently, the contractual analysis drives the British answer just as it drives the American claim of right answer.
Which Year the Relief Falls In
Negative taxable earnings are for the year in which they are paid, not the year in which the original bonus was earned. Therefore, the repayment and the original receipt almost never fall in the same tax year, and they cannot simply be netted off.
HMRC guidance at EIM00810 confirms the approach and stresses that each case turns on its contract. Furthermore, HMRC has published dedicated guidance on claiming a refund for negative earnings, which sets out the practical route.
Section 128 Loss Relief and the Carry-Back
Where negative earnings exceed your positive earnings for the year, the excess becomes an employment loss. Section 128 of the Income Tax Act 2007 then allows that loss to be set against general income of the year of the loss, the preceding year, or both.
That carry-back is the mechanism that usually delivers the money back. Accordingly, a banker who repays a bonus in a year of little other income can reach back to the prior year's earnings. Meanwhile, the claim must be made within the statutory time limit, so a repayment should never sit unclaimed.
National Insurance Is Not Refundable
Here is the British trap that mirrors the American one. A section 128 claim recovers income tax only. National Insurance contributions deducted on the original bonus are not repaid, because the negative earnings analysis does not reopen the original earnings period for contribution purposes.
Consequently, the employee NIC suffered on the clawed-back slice is simply lost, whatever the general guidance on contributions implies about refunds. Notably, the position differs where payroll can correct the payment within the same tax year, because a payroll reversal does adjust contributions. Therefore, the timing of a clawback affects the recoverable amount, not merely the year of relief.
Where the Two Regimes Collide
This is the claim of right analysis no published guide provides, and it is where Americans in Britain lose most of the value.
The Foreign Tax Credit Destroys the Credit Route
The American credit under section 1341 equals the reduction in the earlier year's tax that would have followed had the income never been included. For a UK-resident American, that earlier year's tax on a UK bonus was very often nil, because British rates exceed American rates and the foreign tax credit absorbed the entire liability.
Consequently, the reduction is nil and the credit is nil. The very relief that protected you in the bonus year destroys your claim of right relief in the clawback year. That result surprises every client we explain it to, and it is the single most important point on this topic.
The Deduction Route Fails for the Same Reason
You might expect the claim of right deduction to rescue the position. However, it usually does not, because the clawback year is generally also sheltered by the foreign tax credit. Therefore, an extra deduction reduces a liability that was already zero, and the benefit is nil again.
There is a partial consolation. Specifically, the deduction reduces the American measure of the year's income, which can improve the credit limitation and preserve carryforwards. Nevertheless, that is a second-order benefit rather than cash in hand.
The FEIE Problem
Where the original bonus fell within the foreign earned income exclusion, the position is starker still. Excluded income bore no American tax, so there is nothing for the section 1341 credit to restore. Accordingly, the exclusion and the claim of right rules interact badly whenever a clawback follows.
Different Years on Each Side
Even where both systems give relief, they give it in different years. The American credit restores tax in the year of original receipt, while British negative earnings relieve tax in the year of repayment, subject to the section 128 carry-back. Consequently, the foreign tax credit computations for both years shift, and a repayment can strand credits that were previously usable.
Gross Versus Net Repayment
Employees usually repay the gross bonus, not the net sum they received. Therefore, the cash cost exceeds what actually reached the bank account, and the shortfall is only recovered through the tax relief. Where that relief fails on one side, the employee is genuinely out of pocket rather than merely inconvenienced.
The Sterling Problem
Currency compounds the mismatch. The bonus entered the American return in dollars at the rate for the year of receipt, while the repayment converts at the rate for the year of repayment. Consequently, the dollar amount repaid rarely matches the dollar amount originally included, and the claim of right computation must be run on the original dollar figures rather than on a simple conversion of the sterling repayment.
Claim of Right Relief and Deferred Share Awards
Cash bonuses are the simplest case. Deferred share awards, which dominate senior banking pay, raise harder questions and larger numbers.
Returning Shares Is Not the Same as Repaying Cash
Where an award has vested and the shares were taxed under section 83, a later clawback may require you to return the shares themselves or their cash value. Consequently, the claim of right analysis must identify what was included in income and what is now being given back.
Returning the identical shares is the cleanest position, because the item repaid corresponds directly to the item taxed. Meanwhile, paying cash equal to a later market value creates a mismatch, since the amount repaid may exceed or fall short of the amount originally included. Therefore, section 1341 relief is measured by reference to the amount previously included in income, not by the cash you hand over.
Unvested Awards Forfeited Before Vesting
Forfeiting an unvested award is a different matter entirely. Nothing was included in income, so nothing needs restoring, and the claim of right rules never engage. Accordingly, malus applied before vesting is tax-neutral, while clawback applied after vesting creates the whipsaw this article describes.
That distinction is worth understanding before you negotiate. Specifically, an employer willing to apply malus to unvested awards rather than clawback to vested ones produces a materially better outcome for you, at no cost to itself.
The British Position on Share Clawbacks
Britain treats a share clawback less generously than a cash one. Negative taxable earnings require a payment from employee to employer, and returning shares does not always fit that description comfortably. Consequently, the British relief that rescued the cash case may be unavailable, and the analysis turns again on the precise contractual wording.
Mandatory Clawbacks and Why They Are Increasing
Clawback is no longer a matter of employer discretion, which is why this topic now reaches far more people than it once did.
Listed Company Recovery Policies
American listed issuers must maintain policies requiring recovery of incentive compensation that was erroneously awarded on the basis of financial statements later restated. Consequently, a London-based executive of a US-listed group can face a mandatory repayment demand arising from an accounting restatement he had no part in.
Crucially, those recoveries are not discretionary, so the employer cannot simply waive them to help your tax position. Therefore, the planning has to happen on your side of the table.
Regulatory Clawback in British Banking
British regulators impose their own expectations on material risk takers, with malus and clawback periods running for years after award. Furthermore, HMRC has published guidance precisely because the volume of these cases has grown. Accordingly, anyone in a regulated role should treat a potential clawback as a live planning issue rather than a remote contingency.
Treaty Relief Does Not Solve It
Clients often ask whether the US-UK income tax treaty can realign the two reliefs. It cannot. The treaty allocates taxing rights over income and provides credit relief; it says nothing about which year a repayment should be relieved in. Consequently, the mismatch described above is structural, and no treaty article repairs it.
Deadlines That Decide Whether You Get Anything
Relief on both sides is time-limited, and the limits are shorter than clients expect.
The British Claim Window
A section 128 claim must be made within the statutory time limit running from the end of the tax year of the loss. Therefore, a repayment made in 2025/26 has a fixed and unextendable window, and HMRC will not accept that you were waiting for an American determination.
The American Position
Section 1341 relief is claimed on the return for the year of repayment, so the ordinary filing deadlines govern. However, where the year has already been filed without the claim, an amended return for that year becomes necessary, and the usual limitation period applies. Consequently, discovering a missed claim of right position four years later may be discovering it too late.
A Worked Case Study: £81,000 From HMRC and Nothing From the IRS
Consider a client profile we see whenever markets turn. James is a US citizen and UK resident, a managing director at a London bank. In March 2024 the bank paid him a £300,000 retention bonus subject to a two-year service condition.
Britain taxed it immediately through PAYE. He paid income tax of £135,000 at the additional rate and employee National Insurance of £6,000 at 2%, leaving £159,000 net. On his 2024 American return the bonus was foreign earned income, and because his salary had already absorbed the exclusion, the whole amount entered his gross income. However, the foreign tax credit arising from the £135,000 of UK tax comfortably exceeded the American liability, so his American tax on the bonus was nil.
In January 2026 he resigned, and the contract required him to repay £180,000. The British analysis is favourable. Following *Martin*, the repayment is negative taxable earnings for 2025/26, and a section 128 claim carried back against the prior year's earnings recovers income tax of £81,000 at the additional rate.
The American analysis is bleak. Section 1341 asks what his 2024 tax would have been had £180,000 been excluded from income. Since the foreign tax credit had already reduced that liability to nil, the answer is that it would have been nil either way. Therefore, the credit is zero, the deduction in 2026 is worth nothing against an already sheltered year, and his claim of right relief comes to nothing.
He also loses the £3,600 of employee National Insurance attributable to the repaid slice, because a section 128 claim recovers income tax alone. Ultimately, James repaid £180,000 gross, recovered £81,000 from HMRC, and recovered nothing from the IRS.
Contrast the position had the bonus been paid during his earlier New York posting and taxed in America at 37%. There, the claim of right credit would have restored roughly $66,600 for every $180,000 repaid, because real American tax had been paid in the first place. Consequently, where the bonus was originally taxed determines almost everything about the relief.
What to Do When a Clawback Notice Arrives
The claim of right planning window is short, and the first decisions are the ones that matter.
Get the Contractual Analysis First
Both regimes turn on whether the repayment reverses the original earnings. Therefore, obtain the clawback clause, the bonus award letter and any settlement agreement before anything else. Specifically, wording that describes the payment as a repayment of the bonus supports relief on both sides, while wording that creates a fresh damages obligation undermines it.
Fix the Year, Then the Currency
Establish which American year included the bonus and what tax, if any, that year actually bore after credits. Consequently, you will know within an hour whether section 1341 is worth pursuing at all. Additionally, record the exchange rates for both years, because the two computations must be reconciled.
Claim in Britain Promptly and Protectively
The section 128 claim carries a statutory deadline, and HMRC will not extend it for a taxpayer who was waiting on an American answer. Therefore, make the British claim on time regardless, and treat the American position as a separate exercise. Where the position is uncertain, we file protectively rather than waiting.
Negotiate the Gross Figure Where You Can
Where the clawback is being settled rather than simply enforced, the tax analysis belongs in the negotiation. Notably, an employer indifferent between £180,000 and a slightly lower figure may accept a structure that improves your relief materially. Above all, raise it before signing rather than afterwards.
How TaxYork Can Help
We run the claim of right and negative earnings computations together, which is the only way to see the real outcome. Specifically, we test whether the earlier American year bore any tax after credits, quantify the British negative earnings claim, and tell you the net cash position before you commit to a repayment schedule.
Furthermore, our US tax returns for expats team prepares the section 1341 worksheet, files the credit correctly on Schedule 3, and coordinates the Self Assessment claim so the two years reconcile. Where the clawback interacts with share awards or deferred cash, we model the whole compensation stack rather than the single payment.
Additionally, our tax treaty optimisation specialists reassess the credit position for both years, since a repayment frequently strands carryforwards. Where returns or FBAR and FATCA reports are behind, our IRS Streamlined Filing team brings you current first, and longer-term structuring sits with our cross-border planning team.
Conclusion
The claim of right rules and Britain's negative earnings doctrine both exist to stop you paying tax on money you gave back. Each works reasonably well in isolation. Together, for an American in Britain, they frequently deliver relief on one side only.
The decisive question is where the bonus was originally taxed. Where real American tax was paid, section 1341 restores it at the original rate and the relief is valuable. Where the foreign tax credit or the exclusion had already reduced that year's American tax to nil, the claim of right credit is nil too, however large the repayment. Therefore, model both years before you repay, claim promptly in Britain, and never assume that relief in one country implies relief in the other.
