Domiciled means the country you treat as your permanent home, which is a legal idea separate from where you live. Since 6 April 2025, UK tax depends on residence, not domicile, so the Statutory Residence Test decides how you’re taxed, while domicile still governs succession and other personal law.
If you’re moving to or from the UK, or you have income abroad, our offshore tax advisers can confirm your residence status and how your foreign income and gains are taxed.
This guide covers domicile, the residence tests, the 4-year foreign income and gains regime, Inheritance Tax and certificates of residence.

What Does Domiciled Mean?
Domicile is the country you consider your permanent home and intend to return to. You can have only one domicile at a time, even if you live and work somewhere else.
There are three types of domicile.
- Domicile of origin. You get this at birth, usually from your father’s domicile.
- Domicile of choice. You can acquire this from age 16 by living in a new country and intending to stay there indefinitely.
- Domicile of dependence. Children under 16 usually follow the domicile of the parent they depend on.
HMRC sets out these categories of domicile in its residence and domicile manual.
What Is the Difference Between Domicile and Residence?
Residence is about where you spend your time in each tax year, while domicile is about where your permanent home is. You can be UK resident but domiciled elsewhere, and you can be resident in two countries or in neither.
| Domicile | UK tax residence | |
| What it means | The country you treat as your permanent home | Whether you’re UK resident for a tax year |
| How it’s decided | Your birth, where you live and your long-term intentions | The Statutory Residence Test, based on days and UK ties |
| How often it changes | Rarely, and only with a clear change of intention | It can change from one tax year to the next |
| What it affects from 6 April 2025 | Succession, divorce and other personal law | Income Tax, Capital Gains Tax and Inheritance Tax |
Does Domicile Still Affect UK Tax After April 2025?
For most taxes, no. From 6 April 2025, the remittance basis for non-domiciled residents ended and UK tax on foreign income and gains now depends on residence.
These are the main changes.
- New UK residents can claim the 4-year foreign income and gains (FIG) regime instead of the remittance basis.
- Inheritance Tax on non-UK assets depends on long-term UK residence, not domicile.
- Former remittance basis users can bring pre-April 2025 foreign income and gains into the UK under the Temporary Repatriation Facility, at 12% in 2025/26 and 2026/27 and 15% in 2027/28.
- Domicile still governs succession, divorce and other areas of personal law.
What Is the 4-Year Foreign Income and Gains Regime?
The 4-year FIG regime gives new UK residents 100% relief on foreign income and gains for their first 4 tax years of UK residence. You qualify only if you weren’t UK resident in any of the 10 consecutive tax years before you arrived.
- You claim it on your Self Assessment tax return and choose which foreign income and gains to include.
- For any year you claim, you lose your tax-free allowances for Income Tax and Capital Gains Tax.
- Unused years can’t be carried forward once the 4 years from your arrival have passed.
How Does Inheritance Tax Work for Long-Term Residents?
Since 6 April 2025, you’re a long-term UK resident for Inheritance Tax if you were UK resident in at least 10 of the previous 20 tax years. Your worldwide assets are then in scope for UK Inheritance Tax.
The status doesn’t end the day you leave. It continues for 3 to 10 tax years after you become non-resident, depending on how long you lived in the UK.
How Is UK Tax Residency Determined?
The Statutory Residence Test decides whether you’re UK resident for a full tax year. It looks at the days you spend in the UK and your ties here, in this order.
| Test | Main conditions | Result |
| Automatic overseas test | Fewer than 16 days in the UK, or fewer than 46 days if you weren’t UK resident in the previous 3 tax years | Non-resident |
| Automatic overseas test (working abroad) | Full-time work overseas averaging 35 hours a week, with fewer than 91 days in the UK and no more than 30 of them spent working | Non-resident |
| Automatic UK test (days) | 183 days or more in the UK in the tax year | UK resident |
| Automatic UK test (home) | Your only home is in the UK for at least 91 days in a row, and you spend at least 30 days there in the tax year | UK resident |
| Automatic UK test (work) | You work full-time in the UK for any period of 365 days | UK resident |
| Sufficient ties test | Used if no automatic test applies. Your days in the UK are weighed against your UK ties. | Depends on days and ties |
Under the sufficient ties test, HMRC counts these UK ties.
- A family tie
- An accommodation tie
- A work tie
- A 90-day tie
- A country tie, which only applies if you were UK resident in at least one of the previous 3 tax years
Do UK Residents Pay Tax on Foreign Income?
UK residents normally pay UK tax on their worldwide income and gains, unless they claim the 4-year FIG regime. Non-residents usually pay UK tax only on their UK income.
Non-residents also pay tax when they sell UK property or land. Our guide to Capital Gains Tax on UK property explains how the gain is worked out.
Can Your Residence Status Change During a Tax Year?
Yes. If you move to or from the UK, split year treatment usually divides the tax year into a resident part and a non-resident part.
You won’t get split year treatment if you live abroad for less than a full tax year, so check your residence status each year.
What Happens If You're Resident in Two Countries?
You’re dual resident if the UK and another country both treat you as tax resident at the same time. The tie-breaker rules in the double taxation agreement between them decide which country has the main right to tax you.
You then claim relief in the other country, which usually needs a certificate of residence.
What Is a Certificate of Residence?
A certificate of residence is an HMRC document confirming you’re UK resident, so you can claim tax relief in another country under a double taxation agreement. You can only get one if you’re UK resident and the UK has an agreement with that country.
Individuals apply online or by form. HMRC needs these details.
- Your reason for needing the certificate and which agreement applies
- The type of income and the article of the agreement
- The period the certificate covers
This is separate from the SA109 residence pages, which record your residence status on your Self Assessment tax return. Our personal tax accountants can complete both for you.
