What Is Non-Dom Status? (And Why the UK Abolished It)

What the non-dom regime was, why the UK ended it in 2025, and what replaced it.

Last updated 8 August 2026 · 2 min read

Non-dom, or non-domiciled, status was a UK tax regime that let residents whose permanent home was abroad avoid UK tax on their foreign income and gains unless they brought the money into the UK. The UK abolished it on 6 April 2025 after more than 200 years, replacing it with a shorter, residence-based system.

For more than two centuries the UK's non-dom regime was one of the most famous tax arrangements in the world, and its abolition in 2025 is the largest single tax reform Europe has seen in over a decade. Understanding it explains a wave of wealth now moving across borders.

What non-dom status was

Non-domiciled status applied to UK residents whose permanent home, or domicile, was considered to be abroad. On the remittance basis, a non-dom paid UK tax on UK income and on any foreign income they brought into (remitted to) the UK, but not on foreign income and gains kept offshore. For a wealthy person with substantial overseas income, this was extraordinarily valuable: you could live in London and legally shelter your worldwide income from UK tax.

Why the UK abolished it

A regime that let the wealthy shelter global income while enjoying UK residence became politically indefensible and a target for revenue. On 6 April 2025, after more than 200 years, the UK abolished it. Roughly 74,000 non-doms were directly affected, and some analysts projected a meaningful exodus of wealthy residents, though the exact numbers are contested.

What replaced it

Two separate changes:

  • A four-year Foreign Income and Gains (FIG) regime: new arrivals who were not UK-resident for the previous 10 years get four years exempt on foreign income and gains, even if remitted, then face full worldwide taxation. A Temporary Repatriation Facility lets former non-doms bring old offshore funds onshore at reduced rates.
  • Inheritance tax shifted from a domicile test to a residence test: once UK-resident for 10 of the last 20 years, your worldwide estate is taxed at 40 percent, and the exposure lingers for three to ten years after you leave.

Where former non-doms are going

The reform triggered real movement. The main destinations are the UAE (zero income tax, 10-year golden visa), Italy (a flat 300,000 euros a year on foreign income for new residents from 2026) and Switzerland (lump-sum taxation). See Best Countries for Tax Residency for the trade-offs, and note the UK inheritance-tax tail that follows departures.

Frequently asked questions

What is non-dom status?
Non-domiciled, or non-dom, status was a UK tax arrangement for residents whose permanent home (domicile) was considered to be outside the UK. On the remittance basis, they paid UK tax only on UK income and on foreign income they brought into the UK, sheltering the rest. The UK abolished the regime on 6 April 2025.
Why did the UK abolish non-dom status?
For fairness and revenue. A regime that let wealthy residents shelter worldwide income while living in the UK became politically untenable. From 6 April 2025 it was replaced by a four-year Foreign Income and Gains (FIG) regime for new arrivals, and inheritance tax moved from a domicile test to a residence test.
What replaced UK non-dom status?
A four-year FIG regime: new arrivals not UK-resident for the prior 10 years get four years exempt on foreign income and gains, then full worldwide taxation. Inheritance tax now follows a long-term-resident test (10 of the last 20 years) with a tail after departure. Many former non-doms are relocating to the UAE, Italy or Switzerland.
