The domiciled meaning is simple on the surface. But legally, it runs deep.
In UK tax law, domicile refers to the country you consider your permanent home. Not where you live today, and not where you work this year. This is your long-term home. The place you ultimately belong. For UK tax and residency, it is an important aspect. But many people tend to mistake it for residential property or residential area, which is an entirely different thing. Thus, having a domiciled expert by your side can greatly lessen your hassle.
You can only have one domicile at any given time. That matters a lot.

Domicile vs Residence: Not the Same Thing
People often confuse domicile with residence or being a tax resident. They are different concepts under UK tax law.
Residence is about time in the UK. Domicile is about intention; it is your permanent home. You can be UK resident but non-UK domiciled. However, at the same time you maybe a resident in two countries or neither. The UK looks at each status separately for tax purposes.
How UK Tax Residency Is Determined
Your tax residency status is decided under the Statutory Residence Test (SRT).
This test determines if you are a UK tax resident for a complete tax year.
The SRT has three parts:
- Automatic non-resident test
- Automatic resident test
- Sufficient ties test
The number of days in the UK is crucial. Even at least one day can matter. The more days you spend, the stronger your connection.
Under the sufficient ties test, HMRC looks at:
- Family ties
- Work ties
- Accommodation
- Previous residence
- Days in the UK
Your residence status can change due to significant changes in your life. For instance, you are moving to different countries. Also, you are doing new work or shifting to a new permanent home. But you always check each tax year to consider the upcoming liabilities.
Paying UK Tax as a Resident or Non-Resident
If you are UK resident, you normally pay UK tax on income and capital gains worldwide. Even if it is UK income or a Foreign income, capital gains apply on both evenly.
If you are non resident, you usually only pay tax on UK-source income. You do not pay UK tax on foreign income. Your UK resident status directly affects how your income and gains, including capital gains, are taxed. That includes capital gains tax exposure.
Dual Residence and Double Taxation
Another aspect is the possibility of a be dual resident. If a person is a tax resident in the UK and another country at the same time, then this is called dual residence.
There are many aspects involved about the happenings after you check for a double taxation agreement. These treaties contain tie-breaker rules to decide which country has taxing rights. But to claim tax relief, you may need a tax residency certificate.
What Is a Tax Residency Certificate?
A tax residency certificate is an official certificate that issued by tax authorities. It confirms your tax residency.
It is commonly used to:
- Deal with cross-border taxation
- Claim benefits under double taxation treaties
- Prove where you are liable to tax
If you are resident in two countries, you can apply for a tax residency certificate to claim relief in the other country.
To obtain one, you must apply to the relevant tax authority. The UK government requires evidence, dates, and period of residence. Sometimes they format is SA109 pages with your self assessment tax return.
Domicile Matters Legally
Even after April 2025, domicile governs:
- Succession law
- Divorce rules
- Personal legal systems
Types of domicile include:
- Domicile of Origin (acquired at birth)
- Domicile of Choice (moving with intent to stay permanently)
- Domicile of Dependence (children under 16)
If your only home is outside the UK and you intend to return there, then you are likely non-UK domiciled.
