Non-Domiciled Status (Non-Dom)

Domicile is not the same thing as where you live or where you pay most of your tax. It is a deeper legal idea about where your true, permanent home sits, usually the country you were born into or where your family roots are. Some countries let people who live there but are domiciled elsewhere claim “non-domiciled” status, which changes how their foreign income and gains get taxed.

One thing to say straight away, because most writing about this term has not caught up: the UK, the country that made “non-dom” a household word, no longer has the regime. The remittance basis was abolished, and from 6 April 2025 a residence-based scheme called the foreign income and gains (FIG) regime took its place.

What the remittance basis actually did

This matters when you move country and keep money, property or a business abroad. Under a remittance basis, foreign earnings you leave outside the country may be taxed lightly or not at all, while money you bring in, or “remit”, is taxed normally. That gap is the whole appeal, and the whole risk.

The part the headlines skip is the bookkeeping. Claiming it usually means proving where every pound arriving in the country came from, keeping old capital separate from new income, and running those accounts for years. Paying a local bill with a card billed to an offshore account can count as bringing money in, depending on how the law is drafted.

Non-dom status sits on top of your tax residency, because you normally have to be resident somewhere before you can claim it there at all. Residence is counted from facts like days and ties, and it can flip from one year to the next. Domicile is stickier. It is inherited more than chosen, and you can live somewhere for twenty years without picking it up.

The UK ended its regime on 6 April 2025

Domicile is no longer the connecting factor in the UK system. UK residents are taxed on the arising basis on their worldwide income, with one carve-out for new arrivals: the FIG regime, which runs for a maximum of four consecutive years from the start of UK residence and is open only to people who spent at least the previous ten years as non-UK tax residents. HMRC publishes the conditions, plus transitional rules for anyone who used the remittance basis before that date.

Regimes of this shape still exist, but they are not interchangeable

• Ireland taxes some residents who are not domiciled there on a remittance basis, so foreign income is taxed to the extent it is brought into the country. Revenue sets out who qualifies.
• Malta also operates remittance-basis rules for some residents. Check the conditions with the Maltese tax administration rather than reading them across from anywhere else.
• Cyprus uses a non-domiciled status, but it applies to a specific defence contribution rather than to income tax across the board. It is narrower than the word suggests.

None of these is a copy of the others, and the conditions get revised. That is the honest lesson from the UK: these regimes are political, and they get tightened or repealed. Building a move on one of them means betting that another country’s parliament will not change its mind.

If you hold a US passport, none of it applies to you

The US taxes its citizens and green-card holders on worldwide income wherever they live, and the filing rules are broadly the same abroad as at home. There is no US equivalent of non-dom status, and claiming it in another country does not switch off a US return. That surprises people who move to a remittance-basis country expecting a clean break.

Non-dom is also a different animal from territorial taxation, where a country simply ignores foreign income for everyone, and from a fixed-term perk like NHR, which runs for a set number of years no matter where you are domiciled. Mixing them up is a common and expensive mistake.

If you are weighing a move partly for tax reasons, map your actual residency picture first. A tax residency checker helps you see where you would likely be taxed before you read too much into any non-dom headline. This is general information, not advice. Confirm current rules with the country’s official tax authority (HMRC in the UK, Revenue in Ireland, the IRS if you are American) or a qualified professional, because these regimes change often and the details vary.

Where you’ll meet this

• Reading about Ireland, Malta or Cyprus while comparing where to base yourself, or about the UK in anything written before 2025 that still describes the old rules as live.
• Filling in a residency or tax onboarding form that asks not just where you live, but where you are domiciled.
• Talking to an accountant about keeping a foreign rental, brokerage account or business while living somewhere new.
• Seeing relocation marketing that still sells “non-dom status” as one universal product.
