The UK Statutory Residence Test in 2026: Now That Non-Dom Is Gone, Your Day Count Is Everything

For two hundred years, wealthy people with foreign income had a uniquely British answer to the question of UK tax: be resident, but not domiciled, and claim the remittance basis. Keep the money offshore, keep it out of the UK tax net.

On 6 April 2025, that answer stopped existing.

The non-domicile regime was abolished and replaced with a residence-based system. All UK residents are now taxed on worldwide income and gains as they arise, regardless of where the money sits, with one transitional exception for genuinely new arrivals.

The consequence for anyone with significant foreign income is stark, and it is not widely enough understood: the Statutory Residence Test is now the whole game. Where the remittance basis once offered a way to be UK resident without UK tax on foreign wealth, the only remaining protection is not being UK resident at all. And residence is determined by a mechanical test that turns substantially on counting days.

This guide explains how the SRT actually works, the order in which it must be applied, the tie tables that decide most marginal cases, and what the new four-year regime does and does not do.

What replaced non-dom status

The new regime, which took effect on 6 April 2025, has two main features.

Worldwide taxation for UK residents. If you are UK resident under the SRT, your foreign income and gains are taxable in the UK as they arise. Not when remitted. As they arise, wherever they are held.

A four-year Foreign Income and Gains relief for new arrivals. If you become UK resident after at least ten consecutive tax years of non-UK residence, you can claim relief on foreign income and gains for your first four tax years of residence. After four years, you are taxed on worldwide income like anyone else.

Two things about the FIG regime are worth stating plainly. It is short, four years against a remittance basis that could run for fifteen. And it requires a ten-year clean break beforehand, which excludes most people who have been coming and going.

There is a separate and equally significant change on the inheritance tax side, where liability is now determined by long-term residence rather than domicile. That is beyond the scope of this guide, but if you have been UK resident for an extended period it deserves specific advice.

The net effect is that a status which was once about where your permanent home was is now about how many days you spend here. Domicile was a question of intention and connection, argued over decades. Residence is a question of arithmetic, decided annually.

How the Statutory Residence Test works

The SRT, in Schedule 45 of the Finance Act 2013, has three parts. They are applied in a strict order, and the first part that gives an answer ends the analysis.

This ordering is not a technicality. It is the most commonly mishandled aspect of the entire test, and getting it wrong produces confidently wrong answers.

Part 1: The automatic overseas tests

If any of these apply, you are not UK resident, and nothing below is considered.

• You spend fewer than 16 days in the UK in the tax year, and you were UK resident in one or more of the previous three tax years.
• You spend fewer than 46 days in the UK, and you were not UK resident in any of the previous three tax years.
• You work full time overseas, spend fewer than 91 days in the UK, and have fewer than 31 UK workdays.

Note what this means: someone working full time abroad with 90 UK days is non-resident even if they have a UK home, a UK spouse, and UK work ties. The ties never get counted, because the analysis stopped at part one.

This is the single most valuable thing to understand about the SRT. A great many people assess themselves by counting ties, conclude they are resident, and are wrong.

Part 2: The automatic UK tests

If no overseas test applied, and any of these do, you are UK resident.

• You spend 183 days or more in the UK in the tax year.
• You have a UK home available for at least 91 consecutive days, spend at least 30 days there, and have no overseas home you spend 30 or more days in.
• You work full time in the UK across a 365-day period.

The 183-day test is the one everybody knows, and it is genuinely decisive. But note it is reached only after the overseas tests have been cleared, and note that the home test can make you resident on far fewer days.

Part 3: The sufficient ties test

If neither automatic part decided, residence turns on a combination of days present and the number of connecting factors, called ties.

The five ties are:

• Family tie. A spouse, civil partner, or minor child who is UK resident.
• Accommodation tie. UK accommodation available to you for a continuous 91-day period, in which you spend at least one night.
• Work tie. 40 or more days in the tax year on which you work in the UK for more than three hours.
• 90-day tie. 90 or more days in the UK in either of the two previous tax years.
• Country tie. More days in the UK than in any other single country. This tie counts for leavers only.

Arrivers and leavers face different tables

This is the second major trap. A leaver was UK resident in one or more of the previous three tax years. An arriver was not. Leavers are held to a stricter standard.

Days in the UK	Leaver needs	Arriver needs
16 to 45	4 ties	Cannot be resident on ties
46 to 90	3 ties	4 ties
91 to 120	2 ties	3 ties
121 to 182	1 tie	2 ties

Read that table carefully if you are leaving the UK. A former UK resident spending 130 days in the country needs only one tie to remain UK resident. Having a spouse here is enough. Having a flat available is enough. For someone who has just moved abroad and kept a property in London, the bar is startlingly low.

The country tie applies to leavers only, which produces an asymmetry worth spelling out: identical facts can make a leaver resident and an arriver not, purely because the arriver does not count that tie.

Why this matters more than it used to

Before April 2025, a UK resident non-dom with foreign income could claim the remittance basis and keep offshore income outside UK tax. Residence mattered, but it was survivable.

Now, residence is binary and expensive. Cross into UK residence and your worldwide income and gains are taxable as they arise. There is no remittance basis to fall back on and, unless you qualify for the four-year FIG regime, no shelter.

That has changed behaviour in a specific way: people who previously managed their UK presence loosely now manage it to the day. A single miscounted day can move someone from 45 to 46 days and into a different tie band. For someone with substantial foreign income, that day can be worth more than most people earn in a year.

It has also changed the evidential standard. HMRC has always been able to ask how many days you spent in the UK. The difference is what now turns on the answer.

Counting days correctly

The SRT counts a day as spent in the UK if you are present at the end of the day, that is, at midnight.

Three qualifications matter.

The deeming rule. In certain circumstances, days where you are present but not at midnight can still count. If you have at least three UK ties, were UK resident in one of the previous three tax years, and have more than 30 such days in the year, the excess counts. This catches frequent day-trippers who believed they were leaving before midnight and therefore accumulating nothing.

Transit days. A day spent purely in transit, arriving and departing without engaging in activities substantially unrelated to your passage, does not count, provided you do not stay overnight.

Exceptional circumstances. Up to 60 days may be disregarded where you were prevented from leaving by circumstances beyond your control. HMRC interprets this narrowly. Illness that prevents travel can qualify. A convenient reason to stay does not.

Split-year treatment

A tax year is normally all or nothing. Split-year treatment allows a year to be divided into a UK part and an overseas part where you arrive or leave partway through.

There are eight cases, each with its own conditions, covering situations like starting full-time work abroad, accompanying a partner who does, ceasing to have a UK home, or starting to have one. Split-year treatment applies automatically where the conditions are met; it is not elective.

It is also outside the scope of a day-count calculation, which is why any responsible SRT tool will tell you it is giving you the standard whole-year position and that split-year, exceptional circumstances and the deeming rule can each change the answer.

Common questions

Is 183 days the only thing that matters?

No, and treating it that way is the most expensive simplification in UK tax. You can be UK resident on 16 days with four ties. You can be non-resident on 90 days working full time abroad. The 183-day test is one of eight, and it is reached fourth.

I left the UK last year. Am I automatically non-resident now?

No. You are a leaver, which means you face the stricter tie table. If you kept a home here, or your family remained, you may still be UK resident on relatively few days. The first three tax years after departure are the ones that require care.

Does the UK tax year matter for counting?

Yes. The UK tax year runs from 6 April to 5 April, not 1 January. Counting on a calendar-year basis produces the wrong answer, and it is a common error among people used to other jurisdictions.

Can I still use the remittance basis?

No, not for tax years from 2025 to 2026 onwards. The remittance basis was abolished. The four-year FIG regime is its replacement, and it is available only to those who were non-UK resident for the ten consecutive tax years before arriving.

What evidence does HMRC accept for day counts?

Travel documents, boarding passes, credit card and bank records showing location, mobile phone records, and any contemporaneous log. As biometric border systems replace passport stamps across Europe, stamps are becoming less useful as evidence, which raises the value of independently kept records.

What happens if I get it wrong?

If you have filed as non-resident and HMRC determines you were resident, you face tax on worldwide income for that year, plus interest, plus penalties that scale with whether the error is treated as careless or deliberate. The amounts in dispute in SRT cases are frequently large, because the people affected are frequently the people with substantial foreign income.

Practical guidance

Count to the day, contemporaneously. Not at the end of the year. The bands are 16, 46, 91, 121 and 183, and being one day the wrong side of any of them changes the required number of ties.

Know which band you are in before you book. The useful question is not "how many days have I spent" but "how many can I still spend". Those are different calculations.

Audit your ties annually. Ties change. A child turning 18 removes a family tie. Giving up a UK flat removes an accommodation tie. Two consecutive years under 90 days eventually removes the 90-day tie. People often carry an assumption about their tie count that stopped being true.

Keep evidence for six years. That is the ordinary assessment window for careless error, and longer where HMRC alleges deliberate behaviour.

Get advice on anything marginal. Split-year treatment, the deeming rule and exceptional circumstances are all fact-heavy, and all can flip a result. A calculator gives you the standard position; it does not adjudicate your circumstances.

Three worked examples

The recent leaver

James moved to Dubai in 2025 after fifteen years in London. He kept his flat in Clapham and his wife remained in the UK while their daughter finished school.

He returns for 130 days in the 2026 to 2027 tax year, mostly weekends and holidays.

He is a leaver, because he was UK resident in the previous three tax years. At 130 days he falls in the 121 to 182 band, where a leaver needs one tie.

He has a family tie (his wife). He has an accommodation tie (the flat). He has a 90-day tie (over 90 days in a previous year). He needs one and he has three.

He is UK resident, and with non-dom abolished, his Dubai income is taxable in the UK as it arises. He believed he had left. On the day count he had. On the SRT he had not.

The arriver

Sofia moved to London in 2026 after twelve years in Singapore, with no prior UK residence.

She spends 100 days in the UK in her first tax year.

She is an arriver. At 100 days she is in the 91 to 120 band, where an arriver needs three ties. She has an accommodation tie and a work tie. That is two. The country tie does not count for arrivers.

She is not UK resident for that year, on the same day count that would have made a leaver resident with a single tie.

Note also that because she was non-resident for the ten preceding tax years, she is likely eligible for the four-year FIG regime once she does become resident. Her position is considerably better than James's, for reasons that have nothing to do with how much time either spends in the country.

The full-time worker abroad

Daniel works full time in Frankfurt and returns to the UK for 85 days a year. He has a UK house, a UK wife, and UK work commitments of about 25 days.

Counting ties, he has family, accommodation, work under 40 days so no work tie, and a 90-day tie. Two or three ties, at 85 days, in the 46 to 90 band where a leaver needs three. On a ties analysis he is marginal and might well be resident.

But the ties are never reached. He works full time overseas, has fewer than 91 UK days, and fewer than 31 UK workdays, so the third automatic overseas test applies. The analysis stops at part one and he is not UK resident.

This is why order matters. A tie-first analysis gets this exactly backwards.

The four-year FIG regime in more detail

For those who qualify, the replacement for the remittance basis works roughly as follows.

Eligibility. You must become UK resident after at least ten consecutive tax years of non-UK residence. Returning expatriates who were away for eight years do not qualify.

Duration. Four tax years from the first year of UK residence. It is not extendable, and the clock runs whether or not you claim in a given year.

Effect. Qualifying foreign income and gains are relieved from UK tax. Unlike the remittance basis, you may bring the money into the UK without triggering a charge, which is a genuine improvement on the old regime for those who qualify.

Cost. Claiming has consequences for personal allowances and the capital gains annual exempt amount, so it is not automatically beneficial in a low-income year.

The strategic point is that four years passes quickly. Anyone arriving under FIG should be planning for year five from the outset, because that is when worldwide taxation begins and the planning options are considerably narrower.

Evidence, and why HMRC enquiries turn on it

An SRT position is a self-assessment. HMRC does not agree it in advance. What happens is that you file on the basis you are non-resident, and at some later point HMRC may enquire.

At that stage the burden is practical rather than formal: you are asked to demonstrate your day count. Records that carry weight include travel documents, boarding passes, card and bank statements showing location, mobile phone records, and contemporaneous diaries.

The difficulty in 2026 is that the traditional backbone of this evidence, passport stamps, is disappearing. With the EU's Entry/Exit System replacing stamps across 29 countries, a frequent traveller between the UK and Europe will accumulate very few stamps from here on. The record exists in EU systems, but obtaining it is slow and it does not cover UK arrivals at all.

That leaves a contemporaneous personal record as the most practical evidence most people can produce, and it is materially more persuasive than a reconstruction assembled after an enquiry has opened.

Where iReside fits

The SRT rests on a day count you must be able to evidence, potentially years later, against a tax authority with a strong interest in the answer.

iReside records which country you are in each day automatically. For UK purposes that produces three things worth having:

A contemporaneous record rather than a reconstruction. A diary written at the time is materially more credible than one assembled from boarding passes after an enquiry opens.

A live count against the bands. Knowing you are at 88 days in February, and what that leaves you, is more useful than discovering in April that you finished on 122.

A record that survives the disappearance of passport stamps. With EES now live across the Schengen area and similar systems spreading, the traditional evidence trail is thinning. Your own log is increasingly the best record you have.

To check your position against the tie tables, our free UK Statutory Residence Test calculator runs the three parts in the correct statutory order, handles the arriver and leaver tables separately, and tells you which part of the test decided your result. It runs entirely in your browser.

If your circumstances span multiple countries, our 183-day rule calculator and the guide to international tax residency cover the wider picture, and anyone also managing Schengen limits should read how the EU's Entry/Exit System changed 90/180 enforcement.

The bottom line

The abolition of non-dom status did not make UK tax more complicated. It made it simpler, and considerably more binary.

There is no longer a sophisticated middle position for the internationally mobile. You are either UK resident, and taxed on worldwide income as it arises, or you are not. And whether you are turns on a mechanical test built out of day counts, ties, and an order of operations that most self-assessments get wrong.

The planning that used to happen in trust structures now happens in a calendar.
