Temporary Repatriation Facility (TRF): All You Need to Know

Why the Temporary Repatriation Facility (TRF) Exists

From 6 April 2025, the remittance basis of taxation was abolished as part of the non-dom reforms introduced by the Finance Act 2025. UK-resident individuals can no longer elect to be taxed only on foreign income and gains when those amounts are brought into the UK, as the system has shifted to a residence-based model.

Many former remittance basis users still hold historic foreign income and gains arising before 6 April 2025. Although untaxed at the time, these amounts remain subject to tax if remitted, potentially exposing individuals to income tax rates of up to 45% or prevailing capital gains tax rates, creating a barrier to bringing funds onshore.

The TRF was introduced to provide a structured, time-limited pathway to bring previously untaxed offshore funds into the UK at a reduced tax rate. Its objective is to encourage individuals to "clean up" historic remittance basis income and gains more efficiently than under normal tax rules.

The facility is strictly available for a three-year window covering the 2025/26, 2026/27, and 2027/28 tax years. After this period, no equivalent relief will apply, and standard remittance taxation rules will govern any future remittances.

How the Temporary Repatriation Facility Works in Practice

The TRF operates through a formal designation process. Eligible individuals must identify the amount of qualifying overseas capital they wish to include and make a designation in their UK Self Assessment tax return for the relevant year. This designation gives rise to a TRF charge at the applicable flat rate. Care is required when identifying the correct amounts, particularly for mixed funds or assets instead of cash.

The TRF charge is 12% for designations in 2025/26 and 2026/27, rising to 15% for 2027/28. The rate applies to the net designated amount, and no foreign tax credit can be claimed against the TRF charge. This simplified approach avoids detailed remittance ordering calculations, though taxpayers may still consider whether foreign tax suffered makes designation commercially advantageous.

There is no requirement to remit the designated funds during the three-year TRF window. Once designated and taxed, the amount is treated as capital for UK tax purposes and can be brought to the UK at any time without triggering further income or capital gains tax, allowing flexibility in timing and cash flow planning.

What Can Be Designated

The TRF applies to historic foreign income and gains that arose before 6 April 2025 during a period when the individual was taxed on the remittance basis. This includes amounts held personally offshore, as well as certain amounts held by relevant persons (for example, spouses or trustees) where a remittance would otherwise give rise to a UK tax charge. It can also apply to amounts where the precise source is uncertain, offering a pragmatic solution for individuals with complex banking histories.

Special provisions apply to trust related amounts. In broad terms, capital payments received from non-UK trusts during the TRF window may be designated where they are matched to pre-6 April 2025 foreign income or gains within the trust. In addition, settlors of settlor-interested trusts may be able to designate certain historic trust income that would otherwise have been taxable but for the remittance basis. Careful analysis of trust records and matching rules is essential before making a designation.

The TRF is not limited to cash. It is possible to designate assets other than cash, such as shares, investment portfolios, or overseas property acquired using untaxed foreign income or gains. Where accounts contain both eligible and ineligible funds, the mixed fund rules remain relevant, although amounts designated under the TRF are treated as remitted first. In cases of joint ownership, individuals may designate their proportionate share of the asset or account balance.

Mixed Funds and Practical Structuring

Where offshore accounts contain a mixture of capital, foreign income and gains, and potentially other sources, the mixed fund rules remain highly relevant. However, amounts designated under the TRF are treated as remitted first. This ordering rule can provide clarity and reduce future uncertainty when funds are brought to the UK.

In practice, many individuals establish a separate TRF capital account to hold designated amounts. Segregating these funds can make future remittances simpler and provide a clearer audit trail in the event of HMRC enquiry. Clean fund segregation is particularly important where accounts have lengthy transaction histories or where the source of funds may be difficult to evidence.

Although the legislation permits designation without immediate remittance, careful banking and record keeping will often determine how straightforward the position is in later years.

Strategic Considerations and Planning Risks

The decision to designate is not purely mechanical. Timing can be critical, particularly given the lower 12 percent rate applies only in 2025/26 and 2026/27, rising to 15 percent in 2027/28. Early analysis may therefore produce a material tax saving.

It may not always be optimal to designate funds that have suffered high levels of foreign tax. Because no foreign tax credit is available against the TRF charge, some taxpayers may prefer to rely on normal remittance and credit rules instead. A comparative calculation is often required.

Finally, designations are likely to attract scrutiny, particularly where mixed funds or trust matching are involved. The calculations can be complex, and once the amendment deadline passes the designation cannot be reversed. For these reasons, detailed record keeping and professional advice are essential before making an election under the TRF.
