The Temporary Repatriation Facility Explained
The Temporary Repatriation Facility offers former remittance basis users a rare opportunity: bring decades of offshore wealth into Britain at a flat 12%, rather than at rates reaching 45%. Furthermore, this facility exists for one reason only. When the Government abolished the remittance basis on 6 April 2025, it stranded enormous pools of offshore capital that wealthy residents simply could not touch without a punishing tax bill. Therefore, the Treasury built a transitional bridge. Schedule 10 of the Finance Act 2025 governs the entire regime, and the bridge closes permanently on 5 April 2028.
Importantly, the timing now matters more than the mechanics. Today, in the 2026-27 tax year, you sit in the final year of the 12% rate. Designate in 2027-28 instead and you pay 15%. Consequently, every month of hesitation carries a measurable price.

What the Temporary Repatriation Facility Actually Does
The Temporary Repatriation Facility applies a reduced, flat-rate charge to foreign income and gains that arose before 6 April 2025 while you claimed the remittance basis. You nominate — the legislation says "designate" — a specific amount of that offshore capital. Subsequently, you pay the TRF rate on it. Thereafter, that money moves to the United Kingdom free of any further UK tax charge, whenever you choose to move it.
Notably, the charge does not care what the original income was. Dividends, interest, rental profits, capital gains, and even amounts of genuinely uncertain origin all attract the same flat rate. Additionally, the facility strips away the usual complexity of tracing income through mixed accounts. That simplification alone represents substantial value for anyone whose offshore structure has grown tangled over twenty years.
Why the Clock Is Now the Real Story
Designations made in 2025-26 and 2026-27 attract 12%. However, designations made in 2027-28 attract 15%. After 5 April 2028, the facility disappears entirely, and any remittance of pre-2025 foreign income and gains reverts to your marginal rate — up to 45% for income and 24% for residential property gains.
Consider the arithmetic on £3 million of qualifying capital. At 12%, you pay £360,000. At 15%, you pay £450,000. At a 45% marginal rate after the window shuts, you pay £1,350,000. Therefore, the cost of waiting two years is £90,000, and the cost of missing the window altogether approaches a million pounds.
Who Qualifies and What Counts as Qualifying Overseas Capital
Eligibility for the Temporary Repatriation Facility rests on three conditions, and you must satisfy all three in the tax year you make the designation. Fortunately, the conditions are narrower than most people fear.
The Three Eligibility Conditions
First, you must be UK resident in the tax year of designation, as determined by the Statutory Residence Test. Second, you must have been subject to the remittance basis in at least one previous tax year. Third, you must actually hold qualifying overseas capital available to designate.
The second condition contains a welcome subtlety. For 2008-09 onwards, "subject to the remittance basis" means that sections 809B, 809D or 809E of the Income Tax Act 2007 applied to you — even if you never actively claimed the basis on a return. Consequently, many Americans who benefited from the automatic remittance basis in low-income years qualify without realising it.

What Counts as Qualifying Overseas Capital
Qualifying overseas capital means foreign income and gains that arose in 2024-25 or an earlier tax year, to which the remittance basis applied, and which you have never remitted to Britain. Moreover, the definition reaches further than personal accounts. Amounts held by relevant persons — spouses, minor children, and certain trustees — count where a remittance would have triggered a charge on you.
Additionally, the facility covers amounts of uncertain provenance. Where an offshore account has mingled forty years of income, gains, and clean capital beyond any hope of forensic reconstruction, you may designate the whole balance rather than prove its composition. In our experience advising long-settled American families, this provision alone resolves cases that would otherwise take months of archaeology through dead banks' records.
Certain capital payments from non-UK trusts also qualify, where they match pre-2025 trust income or gains. Similarly, settlor-interested trust income arising before 2025-26 falls within scope.
What Falls Outside the Facility
The Temporary Repatriation Facility excludes income distributions received during the TRF period itself. Likewise, it does not touch income or gains arising from 6 April 2025 onwards; those fall under the new four-year foreign income and gains regime or ordinary arising-basis taxation.
Critically, relief is not available for foreign taxes paid. The charge applies to net amounts after foreign tax has been deducted, but you cannot credit foreign tax against the TRF charge itself. For Americans, that single sentence carries consequences we examine below.

How Designation Works in Practice
Designation is a formal act on a tax return, not a bank transfer. Accordingly, the administration deserves as much attention as the strategy.
Designation Without Remittance
You do not need to bring a single pound into Britain to use the facility. Instead, you designate the capital, pay the charge, and leave the money exactly where it sits. Thereafter, it carries a permanent clean-capital character. You may remit it next year, in a decade, or never.
This point deserves emphasis, because it transforms the decision. You are not choosing whether to repatriate. Rather, you are buying an option — permanently discharging a contingent liability at 12% while the price is low.
The Mixed Fund Ordering Advantage
Where an account holds both designated amounts and other funds, designated amounts are treated as remitted first. Consequently, the ordinarily brutal mixed fund rules of section 809Q ITA 2007 invert in your favour. Instead of the worst money coming out first, the cleanest money leads.
Furthermore, this ordering rule rewards partial designation. You need not designate an entire account to gain useful flexibility from it.

Deadlines You Cannot Miss
You make the designation on your self-assessment return, and you may amend a return to add one. The deadline is the ordinary amendment deadline: one year after the 31 January filing date. For 2025-26, therefore, you have until 31 January 2028. For 2026-27 — the current year, and the last at 12% — you have until 31 January 2029.
However, one restriction bites hard. Only the individual who would be taxable on the remittance may designate that capital. Advisers, spouses, and family members cannot designate on your behalf, regardless of who physically controls the funds. Personal representatives may designate amounts a deceased person received before death, but not amounts received afterwards during administration.
If you remit funds during the TRF period, the designation must appear on the return for the year of remittance or an earlier year. Remit in 2026-27, for instance, and you may designate on the 2025-26 or 2026-27 return.
The American Problem: Why US Citizens Face a Different Calculation
Here the analysis diverges sharply from what your British neighbours face. A UK-only taxpayer weighing the Temporary Repatriation Facility performs simple arithmetic: 12% now against 45% later. An American performs a materially harder calculation, because the United States taxes its citizens on worldwide income regardless of residence.

The Timing Mismatch That Breaks Foreign Tax Credit Relief
The IRS already taxed the income sitting in your offshore account. It taxed it in the year it arose — perhaps 2011, perhaps 2019 — because the United States never recognised the remittance basis. The UK, by contrast, deferred its charge until remittance. Now the TRF charge crystallises in 2026-27, on income the IRS taxed years ago.
That mismatch threatens foreign tax credit relief, and you should not assume the credit works. Two separate questions arise. First, does the TRF charge qualify as a creditable income tax under the regulations at all, given its flat-rate character and its refusal to allow foreign tax relief? Second, even if creditable, to which year does it belong? Foreign tax credits must offset US tax on the same income in the same basket. If the matching US income sits in a long-closed year, there may be nothing in 2026 to credit it against.
Section 6511(d)(3) allows a ten-year window for claims relating to foreign tax credits, which may permit amended returns for more recent arising years. Nevertheless, that window will not reach income from the distant past. Therefore, model the US position before you designate, not afterwards.
https://www.irs.gov/individuals/international-taxpayers/foreign-tax-credit
Currency Gains Under Section 988
Moving money creates US tax events that never trouble a British taxpayer. Where you hold foreign currency and convert it to sterling or dollars, section 988 may treat the exchange movement as ordinary income. A portfolio of euros bought in 2009 and converted in 2026 can carry substantial embedded currency gain, taxed at ordinary rates.
Consequently, the act of remitting — economically neutral in British eyes, since you are merely relocating your own money — can generate a genuine American tax bill. Additionally, the Net Investment Income Tax may add 3.8% on top.

Funding the Charge Without Triggering US Tax
You must pay the TRF charge in sterling to HMRC. Accordingly, you need liquidity. Selling appreciated offshore securities to raise it triggers US capital gains tax immediately, which can erode the benefit you are trying to capture.
Therefore, sequencing matters enormously. We routinely model whether clients should fund the charge from existing sterling, from assets with high basis, from loss harvesting, or from borrowing against the portfolio. Above all, the funding decision should be made alongside the designation decision, never after it.
A Case Study: Designating £4.2 Million in the Final 12% Year
The following illustrative scenario reflects the pattern we see repeatedly among American clients in London.
The Position
An American executive, resident in Britain since 2008, claimed the remittance basis for fourteen years. Her offshore portfolio in Jersey holds £4.2 million of qualifying overseas capital: roughly £1.6 million of accumulated dividends and interest, £2.1 million of realised gains, and £500,000 whose origin no bank statement can now establish. She has filed compliant US returns throughout and paid US tax on the income as it arose. Now she wants to buy a £3 million property in Chelsea.
The Numbers
Without the facility, remitting £3 million would attract UK tax at up to 45% on the income element and 24% on the gains element — a charge comfortably exceeding £1.1 million. Under the Temporary Repatriation Facility, designating the full £4.2 million in 2026-27 costs £504,000 at 12%. Waiting until 2027-28 raises that to £630,000 at 15%.
Notably, she designates the entire £4.2 million rather than only the £3 million she needs. The extra £1.2 million costs £144,000 today and would cost £540,000 to remit later at marginal rates. Furthermore, the £500,000 of untraceable capital — otherwise permanently frozen — becomes usable.
The Outcome
She designates in the current year, pays £504,000, and saves £126,000 against the 2027-28 rate alone. Meanwhile, her US position required careful work. Her adviser modelled the foreign tax credit position across her open years, harvested £180,000 of losses in her taxable portfolio to shelter the section 988 currency gain arising on conversion, and funded the charge from a high-basis holding rather than her most appreciated stock. Consequently, the American tax cost of the exercise fell to a fraction of what an unplanned approach would have produced.
Strategic Considerations Before the 12% Window Shuts
Designation is irreversible. Therefore, several judgements deserve serious thought.
Designate Broadly or Narrowly?
Most advisers instinctively designate only what the client plans to remit. However, that instinct often costs money. Designation buys permanent clean-capital treatment at a historically low rate, and the option value of unrestricted capital is real. Conversely, designating capital you will never touch — because you intend to leave Britain shortly, or because the funds will pass on death without UK exposure — wastes 12%.
The answer turns on your intended residence trajectory and your estate plan. In particular, the wider abolition of the non-dom regime now interacts with these decisions in ways that reward joined-up planning, as our detailed guide for wealthy Americans in Britain explains.

Trust Structures and the Facility
Offshore trusts complicate matters considerably. Capital payments matching pre-2025 trust income or gains may qualify, but income distributions during the TRF period do not. Moreover, American settlors and beneficiaries face the separate machinery of the US grantor trust rules and Forms 3520 and 3520-A, which impose their own penalties entirely independent of the UK analysis.
Consequently, trust cases demand parallel UK and US modelling before any designation. Never designate trust-related capital on UK advice alone.
https://www.gov.uk/guidance/trusts-and-taxes
Interaction With the Four-Year FIG Regime
The facility addresses only pre-6 April 2025 capital. Separately, the four-year foreign income and gains regime governs new arrivals, exempting qualifying foreign income and gains for their first four years of UK residence. If you recently arrived, or if you left and returned after ten years abroad, these regimes interact.

How TaxYork Can Help
TaxYork specialises exclusively in the intersection where the Temporary Repatriation Facility becomes genuinely difficult: American taxpayers with substantial UK-resident wealth. We are not a UK firm that also handles US returns, nor an American firm with a London postbox. Rather, we model both systems simultaneously, because that is the only way these decisions can be made correctly.
Our work on a TRF engagement typically covers quantifying your qualifying overseas capital across accounts and structures, modelling the US foreign tax credit position across every open year, calculating the section 988 exposure on any planned conversion, designing the funding strategy to minimise American tax leakage, and preparing the designation on your self-assessment return. Additionally, we coordinate with your existing wealth managers and trustees rather than displacing them.
Furthermore, many clients approach us with historic US compliance gaps alongside the TRF question. Where that applies, the IRS Streamlined Filing Compliance Procedures often resolve the position without penalty before designation proceeds. Our published guidance on double reporting of UK capital gains covers the mechanics that most frequently catch American clients out.

Conclusion
The Temporary Repatriation Facility represents the most valuable transitional relief in a generation of British tax policy, and it is wasting away in real time. You are currently in the last tax year at 12%. From 6 April 2027, the rate climbs to 15%. From 6 April 2028, the facility vanishes and pre-2025 offshore wealth reverts to marginal rates approaching 45%.
For Americans, however, the decision is never simply about the 12%. The UK charge is the straightforward part. The genuinely difficult work lies in the foreign tax credit analysis, the currency gain exposure, the funding sequence, and the trust machinery — all of which must be modelled before you designate, because designation cannot be undone.
Ultimately, the clients who capture the most value from this facility are those who started the analysis early. Therefore, if you hold pre-2025 foreign income and gains and you have not yet modelled your position, that work should begin now rather than in the closing weeks of the window.
