The Remittance Basis: A Guide to What It Was and How It Ended

For decades, the UK's non-domicile rules — and specifically the remittance basis of taxation — were among the most significant draws for internationally wealthy individuals choosing where to base themselves. The UK offered world-class financial services, rule of law, education, and cultural life, with a tax framework that could protect overseas income and gains from UK tax indefinitely, provided they remained outside the UK.

That framework was abolished from 6 April 2025. Understanding what existed before — and what the transitional arrangements are for those who used the remittance basis — remains essential for anyone affected.

What Was the Remittance Basis?

The remittance basis was an optional method of UK taxation available to individuals who were resident in the UK but not UK-domiciled. Domicile is a common law concept, distinct from residence or nationality — broadly, it is the jurisdiction you regard as your permanent home. Most British nationals are domiciled in the UK. Many foreign nationals resident in the UK are non-UK domiciled.

Under the remittance basis:

• UK income and gains were always taxed in the UK on the normal "arising basis" — taxable as they arose, regardless of where the money ended up.
• Foreign income and gains were only taxable in the UK if they were "remitted" — brought into or used in the UK, or used to benefit the taxpayer in the UK.

Foreign income left offshore — in a non-UK bank account, reinvested overseas, or simply retained abroad — was not taxed in the UK. Ever. Provided the money never crossed into the UK.

For wealthy individuals with significant overseas investment portfolios, business interests, or capital accumulated before they came to the UK, the remittance basis meant the UK was, in tax terms, a highly attractive base that did not disturb their existing wealth.

How You Used the Remittance Basis

Electing for the remittance basis was done annually on the self-assessment tax return. There was no automatic entitlement — you claimed it each year.

The principal costs of claiming:

• Loss of the personal allowance for income tax (£12,570 in final years — a relatively small cost against substantial overseas income).
• Loss of the CGT annual exempt amount (£3,000 in final years — again, small).
• The Remittance Basis Charge (RBC): After 7 years of UK residence, a mandatory annual charge applied if you were claiming the remittance basis:
  • £30,000/year for those resident in the UK for at least 7 of the past 9 tax years.
  • £60,000/year for those resident for at least 12 of the past 14 tax years.

For individuals with hundreds of thousands or millions in overseas income, the RBC was a small price to pay. For those with modest overseas income, the remittance basis was often not worthwhile.

Clean Capital and the Complexity of Remittance

The practical management of the remittance basis was complex. "Remittance" is defined broadly — not just cash transferred to a UK bank account, but also:

• Using overseas income to pay for services enjoyed in the UK.
• Using a foreign credit card in the UK (where the card balance is repaid from overseas income).
• Bringing overseas investments to the UK.
• Certain transfers to UK-resident spouses.

Managing what was "remittable" required maintaining meticulous records of the source of all overseas funds. Individuals typically needed multiple offshore bank accounts segregated by type: pre-arrival "clean capital" (which was never subject to UK tax and could be brought to the UK freely), post-arrival foreign income, post-arrival foreign gains, and mixed accounts.

This administrative burden was significant. Many non-doms employed dedicated tax advisers and maintained complex account structures specifically to manage remittance basis compliance.

The Policy Debate

The remittance basis was politically controversial throughout its existence. Critics argued that it was a privilege available only to the very wealthy, allowing high-net-worth foreign nationals to live in the UK, use public services, and enjoy its legal and cultural infrastructure without paying UK tax on the income that funded their lifestyle — provided they kept their money offshore.

Supporters argued that non-doms with remittance basis status still paid substantial UK tax on UK income and gains, made significant economic contributions (investment, employment, consumer spending), and that many would simply leave the UK if the basis were removed — reducing rather than increasing total tax revenues.

Both sides had evidence on their side. The empirical question — what happens to the tax base when you remove the remittance basis — is now being answered in real time.

The April 2025 Abolition

The Labour government, which won the general election in July 2024, confirmed the abolition of the remittance basis from 6 April 2025. The replacement is the Foreign Income and Gains (FIG) regime — a four-year window of full tax relief on overseas income and gains available only to genuinely new UK arrivals who have not been UK resident in the prior 10 years.

For existing non-doms who had been using the remittance basis — and who did not qualify as "new arrivals" — the April 2025 change meant they transitioned directly to the arising basis of taxation: worldwide income and gains taxable in the UK from that date.

The Temporary Repatriation Facility (TRF)

The most immediate practical issue for long-standing remittance basis users was what to do with the unremitted foreign income and gains that had accumulated offshore over years or decades.

Under the old rules, these were deferred — not forgiven. If the money was ever brought to the UK under the old rules, UK tax would have applied at the time of remittance. With the remittance basis gone, the theoretical threat was that HMRC would seek to tax them at standard rates on any future UK use.

The Temporary Repatriation Facility addresses this. For three years — 2025-26, 2026-27, and 2027-28 — former remittance basis users can designate pre-6 April 2025 foreign income and gains as "TRF amounts" and remit them to the UK (or simply designate them, without physical remittance) paying tax at a preferential rate:

• 12% in 2025-26 and 2026-27.
• 15% in 2027-28 (confirmed in Finance Act 2025 — note this is higher than the 12% rate in earlier years, creating an incentive to act sooner rather than later).

After the TRF window closes, any remaining unremitted pre-April 2025 foreign income and gains retain their character as potentially taxable on remittance — at standard rates. For those with very large offshore pots, the TRF decision is significant.

Why use the TRF?

• It "cleans" the offshore funds — once designated as TRF amounts and the tax paid, those funds can be used anywhere (including in the UK) without further UK tax consequence.
• The 12% rate is well below the income tax rate of 45% (additional rate) or the CGT rate of 24% that would have applied at standard rates.
• For wealthy individuals who intend to remain in the UK and will eventually bring or use overseas funds, the TRF eliminates the ongoing compliance burden of segregating remitted and unremitted amounts.

Why not use the TRF?

• If you intend to leave the UK permanently before using the offshore funds, there may be no benefit — you would not remit them to the UK anyway.
• If the offshore funds are in jurisdictions with their own tax on remittance or withdrawal, there may be double taxation considerations.
• If the TRF rate is still higher than the effective rate you would pay in future years (for example, if you expect significantly lower income in later years), waiting may be rational.

These decisions require individual calculation and professional advice.

What Former Remittance Basis Users Should Do Now

If you were a UK resident non-dom who used the remittance basis before April 2025:

1. Quantify unremitted foreign income and gains — this requires reviewing all overseas accounts and understanding which funds represent pre-April 2025 unremitted amounts versus post-April 2025 arising basis amounts.

2. Assess the TRF option — model the total tax cost of designating some or all unremitted amounts at 12% versus retaining them offshore and paying standard rates if ever used.

3. Review UK residence intentions — the TRF is only valuable if you are going to remain in the UK or want to bring funds in. If you plan to leave the UK imminently and permanently, the TRF window may be irrelevant.

4. Check the LTR IHT test — the new Long-Term Resident IHT test (10 of 20 years UK resident → worldwide IHT) may apply to you now or shortly. If it does, excluded property trust planning — for assets not yet settled — should be reviewed urgently.
