If you split your time between the UK and a country where you hold a golden visa, the calendar matters more than ever. From 6 April 2025, the old non-dom remittance basis was replaced by the 4-year Foreign Income and Gains regime. For many internationally mobile people, UK tax exposure now depends heavily on whether they are UK tax resident under the Statutory Residence Test.

This is the part golden visa holders often underestimate. A residence permit abroad does not, by itself, take you out of UK tax. The 2 questions sit side by side. You need to manage both your immigration status and your tax residence. Understanding the difference between residency and citizenship by investment is a sensible starting point, because the obligations attached to each are not the same.

How the UK day count works

The Statutory Residence Test has applied since 6 April 2013. In broad terms, a UK day is usually counted where you are in the UK at midnight, although there are limited exceptions and anti-avoidance rules.

Spend 183 days or more in the UK in a tax year and you are automatically UK resident. Below that, the answer depends on automatic overseas tests, automatic UK tests and the sufficient ties test. Those ties include family, accommodation, work, a 90-day pattern and, for someone recently UK resident, a country tie. The GOV.UK Statutory Residence Test guidance sets out the full mechanics.

UK days in a tax year	Why it matters
Fewer than 16	Usually enough to remain non-resident if you were UK resident in at least 1 of the previous 3 tax years
Fewer than 46	Usually enough to remain non-resident if you were not UK resident in any of the previous 3 tax years
16 to 182	Residence depends on your UK ties and whether an automatic test applies
183 or more	Automatically UK resident

A short example

Picture someone who secures a Greek residence permit and assumes they have left UK tax behind. They keep a flat in London, their children are at school here, and work brings them back for short trips. Those facts are ties. Add enough ties and a much lower day count can still create UK residence.

The lesson is simple. Plan the days before the tax year starts, not after. This is exactly why our piece on Greek tax residency versus the Greek golden visa is worth reading if Greece is on your list, alongside the features of a financially independent person visa in Greece.

What changed in 2025 and why it bites in 2026

The 4-year Foreign Income and Gains regime is available to qualifying UK residents who are within their first 4 years of UK tax residence after at least 10 consecutive tax years of non-UK residence. If you claim, eligible foreign income and gains can be relieved from UK tax. However, you lose certain tax-free allowances for Income Tax and Capital Gains Tax for the year claimed.

Inheritance tax has also moved to a residence-based system. From 6 April 2025, a long-term UK resident can bring overseas assets into the UK inheritance tax net. Broadly, this can apply once you have been UK resident for 10 of the previous 20 tax years, with a continuing exposure after departure that can last up to 10 tax years depending on your history.

For internationally mobile families, this raises the stakes on residence planning. Our guides to residency planning for UK families looking at Hungary and Italian tax treatment for new residents show how different countries approach the same issue.

Programmes that suit a day-counting strategy

Some routes carry light or flexible stay requirements, which can help if your aim is to control where you are tax resident. Others give mobility without a residence obligation after citizenship is granted.

The Hungarian investor visa offers a residence permit route with no general minimum stay requirement for maintaining the permit, although applicants still need to meet the immigration rules and investment conditions.

Caribbean citizenship programmes can also be useful where the aim is mobility rather than residence. Antigua and Barbuda’s investment citizenship currently starts from a US$230,000 National Development Fund contribution, while St Lucia’s citizenship by investment programme starts from a US$240,000 National Economic Fund contribution.

Malta needs careful wording. EU citizenship through Malta’s investment programme is no longer available in the old structured investor-naturalisation form. Malta now focuses on a discretionary merit-based naturalisation framework, so it should not be treated as a simple investment timetable.

Minimum stay rules vary widely between countries, as our look at Portugal golden visa minimum stay rules makes clear. The right choice depends on whether you want to be present in a country, or specifically need flexibility to avoid creating tax residence there.

Frequently asked questions

How many days can I spend in the UK without becoming tax resident?

There is no single safe number for everyone. 183 days makes you automatically UK resident, but fewer days can still count if you have enough UK ties.

What counts as a day in the UK?

Usually a day where you are in the UK at midnight. There are limited exceptions, so keep clear travel records.

Does a golden visa make me non-UK resident?

No. Holding residence abroad does not by itself end UK tax residence. Your UK position is decided separately under the Statutory Residence Test.

Is the non-dom remittance basis still available?

No. It was replaced from 6 April 2025 by the residence-based Foreign Income and Gains regime.
