The rule: relieved money moves freely
Under the old remittance basis, foreign income and gains escaped UK tax only while they stayed offshore, and bringing them in later triggered tax at full rates. The FIG regime abandons that architecture. HS266 puts it plainly: you do not have to bring your tax-relieved foreign income and gains to the UK, but if you choose to, there is no tax liability when you do. Relieved dividends can pay a London deposit and a relieved disposal can clear a mortgage, with nothing further due. That is a structural improvement over the remittance basis, and it changes behaviour: there is no longer any tax reason to strand money offshore during your first four years of UK residence.
The boundary: only relieved amounts, only claim years
The freedom has a precise edge. It applies to income and gains relieved by a valid FIG claim, which means a claim made on the SA109 for a qualifying year with every amount quantified source by source. Foreign income that arises in a year you do not claim is simply taxable as worldwide income, and bringing it in changes nothing either way. The other boundary is historic money. If you used the remittance basis before 6 April 2025, your old unremitted foreign income and gains are still taxable on remittance under the old rules; the route in for that money is the Temporary Repatriation Facility, which HMRC's guidance charges at 12% of designated amounts for 2025/26 and 2026/27, rising to 15% for 2027/28. The 12% window closes on 5 April 2027, so mixing new relieved money with old untaxed money in one account is an expensive habit; our record-keeping guide sets out a clean structure.
