The three-year window and its rate ladder
The TRF was introduced by Finance Act 2025 alongside the abolition of the remittance basis from 6 April 2025. HMRC's HS264 helpsheet confirms it is a temporary measure available for three tax years: 2025/26, 2026/27 and 2027/28. The charge is a flat 12% of qualifying overseas capital designated in 2025/26 or 2026/27, and 15% for designations in 2027/28. There is no indication of an extension. Our full Temporary Repatriation Facility guide covers eligibility, mixed funds and the funding trap in detail.
What the deadlines mean in practice
Two dates matter more than the headline closure. The cheaper 12% rate is only available for designations made for the 2025/26 or 2026/27 tax years, and 2026/27 ends on 5 April 2027. After that, the final year, 2027/28, is charged at 15%: on each £100,000 designated, that is £15,000 instead of £12,000. The facility then closes altogether on 5 April 2028. Designation runs through Self Assessment on the SA109 residence pages, and quantifying qualifying capital, especially in mixed funds, takes real lead time, so the work should start well before the filing deadline for the chosen year.
What happens after 5 April 2028
Helpfully, you do not have to bring the money to the UK while the facility is open. Once an amount is designated and the charge paid, HMRC confirms it can be remitted at any time in the future with no further tax, including long after the TRF has closed. Undesignated pre-6 April 2025 foreign income and gains, by contrast, fall back into the normal remittance rules, where foreign income can be taxed at up to 45% when brought to the UK. The TRF only deals with old money: new foreign income of recent arrivals is a matter for the separate 4-year FIG regime.
