US UK Tax Returns Preparation: Bonus Clawback and Malus

When a London banker repays a bonus that was taxed in both countries, neither return is simply reversed. The US generally gives relief in the year of repayment, either as a deduction or through the section 1341 claim-of-right credit. The UK treats a contractual cash clawback as negative earnings in the tax year you repay. Forfeited unvested shares usually need no repayment claim at all.

That short answer hides a sequence of preparation decisions that is easy to get wrong, and expensive when it is. This guide sets out how US UK tax returns preparation should handle a bonus clawback or malus adjustment for a US citizen or green card holder working in financial services in London: which year is affected, which form carries the relief, how the original foreign tax credit interacts with the repayment, how sterling is translated into dollars, and what to do first if the bonus-year returns were never filed. At Jungle Tax we prepare these returns every season for senior bankers, traders and portfolio managers, and the same handful of errors appears again and again.

Why a bonus repayment is a two-country return problem

Regulated firms in the UK are required to build malus and clawback provisions into variable remuneration for material risk takers, and the deferral periods that go with them can run for several years. The result is that an adjustment can land long after the bonus was paid, taxed under PAYE in the UK, reported as wages on a US Form 1040 and sheltered there with a foreign tax credit.

Most published guidance deals with only one side. US articles explain section 1341 for a domestic employee repaying a signing bonus, with no mention of foreign tax credits, sterling or HMRC. UK articles explain negative taxable earnings for a UK-only taxpayer, with no mention of the IRS. A dual filer needs both answers at once, reconciled across two different tax years: the UK year runs from 6 April to 5 April, while the US year is the calendar year. A bonus paid in March and repaid the following October can sit in different years on each side of the Atlantic.

First question: was taxed income actually repaid?

Before any form is prepared, identify precisely what happened. The words "malus" and "clawback" are used loosely inside firms, but for return preparation there are only three situations that matter.

• Clawback of a cash bonus already paid. You received the cash, it was taxed, and you now pay money back to the employer. This is the case where relief must be claimed on both returns.
• Malus applied to an unvested or unpaid deferred award. Deferred cash or share units are reduced or cancelled before they vest or are paid. In the ordinary case nothing was ever taxed, so nothing is repaid and there is no relief to claim.
• Clawback of shares or share proceeds after vesting. Shares that were taxed on vesting are returned, or their value is repaid in cash. This is the least straightforward case, and the two countries may not treat it symmetrically.

Obtain the clawback letter, the plan rules or contract clause relied on, the date and amount of each payment you made, whether the firm demanded the gross or net amount, and evidence of the original payment (payslip, P60 and the US wage figure used). Every later step depends on these facts.

How is a bonus repayment handled on the US return?

The US starting point is the annual accounting principle. A bonus received with no restriction on its use is income in the year received, even if you later have to give it back. The earlier return is normally not amended simply because the money was repaid. Instead, relief is taken in the year of repayment, under rules summarised in the IRS guidance on repayments in Publication 525, Taxable and Nontaxable Income.

Repayment in the same calendar year

If you receive and repay the bonus in the same calendar year, the repayment simply reduces the wages you report for that year. For a London banker paid through UK payroll there is no corrected W-2 to wait for, so the preparer adjusts the foreign earned income figure directly and documents why it differs from the P60 and payslips.

Repayment in a later year: deduction or section 1341 credit

Where the repayment happens in a later year, the treatment depends on the amount repaid:

• $3,000 or less. Under current federal law this falls into the category of miscellaneous itemised deductions that are not allowed, so in most cases there is no federal relief.
• More than $3,000. The claim-of-right rule in Internal Revenue Code section 1341 applies. You calculate your tax both ways and pay the lower figure: either (Method 1) take an itemised deduction for the repayment in the current year, or (Method 2) take no deduction and instead claim a credit equal to the tax that would have been saved in the original year had the repaid amount never been included.

Section 1341 is available only where it appeared, in the year of receipt, that you had an unrestricted right to the bonus, and it was later established that you did not. A contractual clawback triggered by the plan rules normally fits that pattern; a purely voluntary repayment may not. The claim is not made automatically by tax software, and the calculation must be attached to the return.

Why the deduction route is often worth less to a UK resident

Two features of the expatriate position change the arithmetic. First, the deduction is only useful if you itemise, and many overseas filers claim the standard deduction. Second, a deduction for repaid foreign wages is allocated against foreign-source general category income, which reduces the Form 1116 limitation in the repayment year. If your UK tax credits already exceed your US tax on UK earnings, a deduction may save little or no US tax. That is why the credit method has to be modelled rather than assumed.

How does the original foreign tax credit interact with section 1341?

This is the part generalist guides miss, and it is where the largest errors occur. Method 2 requires a recomputation of the original year's US tax as if the repaid bonus had never been included. For a London banker that recomputation is not just a change to wages; it is a full rerun of Form 1116 for that year.

1. Remove the repaid amount from foreign-source general category wages in the bonus year, translated at the dollar value originally reported.
2. Recompute the foreign tax credit limitation. Lower foreign-source income reduces the limitation, so the credit allowed in that year may fall as well as the tax before credits.
3. Recompute carryovers. If the original year generated excess UK credits that were carried back or forward, the recomputed year may generate a different excess, and the carryover schedule in later years must follow.
4. Measure the decrease in tax. The Method 2 credit is the net reduction in the original year's US tax after credits. If UK tax had fully sheltered the bonus from US tax, that decrease can be small.

The practical conclusion is uncomfortable but important: for many UK-resident dual filers the US relief is modest, because the US never collected much tax on the bonus in the first place. The real economic recovery usually comes through the UK. The US task is to make the claim that produces the lower tax, keep the credit carryovers accurate, and avoid overstating relief in a way that invites an adjustment later.

When UK relief itself changes your US foreign tax credit

The UK relief described below reduces UK tax. Where that reduction is given in the UK year of repayment, it simply lowers the UK tax available as a credit for the corresponding US year. Where, however, UK relief is obtained by reducing tax for an earlier UK year, or by a repayment of tax already credited on a US return, the US treats it as a potential foreign tax redetermination. The IRS foreign tax credit guidance in Publication 514 requires the IRS to be notified of a redetermination, generally by amended return with Schedule C of Form 1116, and a penalty can apply for failure to notify without reasonable cause.

How does the UK treat repaid bonus income?

For many years it was assumed that no UK relief was available when an employee repaid taxed earnings. A 2014 Upper Tribunal decision on a repaid signing bonus changed that, and HMRC's Employment Income Manual now recognises the concept of negative taxable earnings. The guidance at EIM00805 and the worked example at EIM00845 set out HMRC's position. As always, the result depends on the precise contractual terms, and the tribunal itself stressed that its decision turned on the contract in front of it.

Relief is given in the year you repay, not by reopening the bonus year

The UK does not re-tax the original bonus year at a lower figure. Instead, the repayment is treated as negative earnings from the same employment in the tax year in which you make the payment. Those negative earnings are set against your positive earnings from that employment in that year, which can produce a refund of PAYE already deducted from salary or later bonuses. Where the negative figure exceeds your earnings from the employment in that year, HMRC's manual indicates that loss relief under section 128 of the Income Tax Act 2007 may be available against general income. The scope, sequencing and time limit for that claim should be confirmed on the facts.

PAYE, National Insurance and how the claim is made

• The employer's PAYE and Real Time Information submissions for the original payment are not corrected.
• HMRC's guidance states that no relief or repayment of National Insurance contributions is available on a clawed-back amount.
• Relief is claimed from HMRC for the year of repayment, in practice through your Self Assessment return for that year, with a clear note explaining the negative earnings and the contractual basis.

Gross versus net repayment

Firms frequently require repayment of the gross bonus, including the income tax deducted under PAYE, because the employer cannot recover that PAYE from HMRC. You therefore repay more cash than you received and look to the negative earnings claim to recover the tax. Where only the net amount is repaid, the amount of negative earnings, and therefore the relief, is correspondingly smaller. The same gross or net figure drives the US deduction or section 1341 computation, so both returns must use a consistent number.

If you have left the UK or the employer before repaying

Clawback is often triggered by departure. If you have left the firm, there may be few or no earnings from that employment in the repayment year to absorb the negative amount, which pushes the claim onto the general income route. If you have also ceased UK residence and returned to the US, the question of what UK income remains to be relieved becomes central. These cases need the UK and US computations prepared together so the foreign tax credit consequences are captured on the US side.

What if the original UK return was wrong or the year is closed?

Because UK relief attaches to the year of repayment, it is not generally necessary to reopen the bonus year. The timing tools still matter in two situations: where an error in the original return is discovered while the clawback is being reviewed, and where the claim for the repayment year was missed. A Self Assessment return can normally be amended within twelve months of the filing deadline for that year. After that, HMRC's overpayment relief guidance sets out a separate claim route, which is generally subject to a four-year time limit and to exclusions. Overpayment relief is not a substitute for a claim that has its own statutory procedure, so the correct claim must be identified first.

US vs UK treatment at a glance

Cash clawback versus forfeited deferred shares

Deferred remuneration for senior bankers is typically a mix of deferred cash and share-based awards, and the distinction between them decides whether there is anything to put on a return.

Malus on unvested share awards

Restricted stock units and nil-cost options are generally taxed in the UK on vesting or exercise, and in the US when the shares are delivered or become substantially vested. If malus cancels the award before that point, no income arose in either country. There is no repayment of taxed income, no section 1341 claim and no negative earnings claim. The only preparation task is to make sure the cancelled award is not reported, which can happen when a preparer relies on an equity statement that still shows the original grant. Our guide to cross-border equity compensation covers the vesting side in detail.

Clawback of vested shares

Where shares that have already been taxed must be returned, the positions diverge. In the UK, share awards taxed on vesting are generally treated as specific employment income rather than general earnings, and HMRC's approach is that the negative earnings relief applies to general earnings only. That suggests a return of shares may attract no UK relief, although the analysis depends on how the award and the clawback operate. In the US, repayment of amounts previously included in wages may support a deduction or section 1341 claim, but the amount and character of any relief, and the interaction with any later share disposal, require careful analysis.

Restricted shares with an upfront election

Where shares were issued at grant and an election was made to be taxed at that point, a later forfeiture does not generally produce a deduction for the value already taxed in the US. The UK treatment of such awards depends on the election and plan terms. These arrangements are uncommon in regulated deferral structures but should be checked.

Translating the repayment from sterling into dollars

US returns must be prepared in dollars, and a repayment made in sterling months or years after the bonus was paid will rarely translate to the same dollar figure. Three points need to be settled and documented.

• The original inclusion. Confirm the dollar amount of the bonus reported in the original year and the rate used, because the section 1341 recomputation removes that figure.
• The repayment. A discrete sterling repayment is generally translated at the rate on the date of payment. If sterling has moved, the dollar value repaid can differ materially from the dollar amount originally taxed.
• The mismatch. Where the dollar value repaid exceeds, or falls short of, the dollar amount originally included, the treatment of the difference is not straightforward and should not be buried in a rounding line. Document the approach and apply it consistently across the deduction, the credit calculation and Form 1116.

What if the bonus-year returns were never filed?

This situation is more common than firms assume, particularly for accidental Americans and long-term London residents who have only recently discovered their US filing obligations. It changes the order of work.

Section 1341 relies on an item having been included in income for a prior year. If no US return was filed for the bonus year, nothing was included, and there is no credit to measure. The bonus-year return must be prepared first, reporting the bonus as wages and claiming foreign tax credits for the UK tax paid. Only then can the repayment year be prepared correctly.

For a taxpayer whose failure to file was non-wilful, the IRS Streamlined Foreign Offshore Procedures are often the appropriate route. They generally require the last three years of delinquent or amended income tax returns and the last six years of FBARs, together with a certification of non-wilful conduct. A bonus paid into a UK bank or brokerage account is also relevant to FBAR and Form 8938 reporting in the year received, so the catch-up must cover information returns as well as income. Where the catch-up and the clawback overlap, the streamlined years should be chosen and prepared with the repayment already in view.

On the UK side, PAYE will normally have been deducted from the bonus, but higher earners with complex affairs are often required to file Self Assessment. If returns for the bonus year or the repayment year were not filed when required, late returns should be prepared, and the negative earnings claim made through the repayment-year return. Our UK tax return preparation team handles both.

A worked sequence for a London banker

Consider an illustrative case. A US citizen living in London receives a cash bonus of £400,000 in March 2025, taxed under PAYE and reported on a 2025 US return with foreign tax credits. In October 2026 the firm invokes clawback and requires repayment of £250,000 gross. The preparation sequence would be:

1. Confirm the facts: the contractual clawback clause, gross or net basis, payment date and evidence of payment.
2. Map the years: the bonus fell in UK tax year 2024-25 and US year 2025; the repayment falls in UK tax year 2026-27 and US year 2026.
3. Prepare the UK claim: treat the £250,000 as negative earnings for 2026-27, set it against earnings from the same employment in that year, and consider any excess under the loss relief rules.
4. Translate the repayment into dollars at the October 2026 rate and reconcile it with the dollar amount included in 2025.
5. Model both US methods for 2026: the itemised deduction (with its effect on the Form 1116 limitation) and the section 1341 credit (with a full recomputation of 2025 tax and credits).
6. Update foreign tax credit carryovers and check whether the UK relief amounts to a redetermination of UK tax credited in any earlier US year.
7. File consistently: the same gross figure, the same dates and a clear explanatory statement on both returns.

The figures above are hypothetical and chosen only to show sequencing; the actual relief depends on each year's income, credits and rates.

Documents to assemble before preparation

• Clawback or malus notice and the relevant plan rules or contract clause
• Proof of repayment, with dates, amounts and currency
• Payslips, P60 and P11D for the bonus year and the repayment year
• Filed US returns, including every Form 1116 and carryover schedule, for the bonus year onwards
• Filed UK Self Assessment returns and calculations for the same years
• Equity plan statements showing grants, vesting, forfeitures and any shares returned
• Records of any exchange rates already used in earlier returns

Common preparation errors we correct

• Amending the US bonus-year return to remove the bonus, instead of claiming relief in the repayment year.
• Claiming a section 1341 credit calculated from the original year's tax before credits, ignoring the foreign tax credit already allowed.
• Reporting forfeited unvested awards as income, or claiming relief for them.
• Omitting the UK negative earnings claim altogether because the employer's P60 is unchanged.
• Using the net repayment on one return and the gross repayment on the other.
• Leaving foreign tax credit carryovers unchanged after the recomputation.
