How many days can you spend in the UK?

There's no single answer: your allowance depends on the ties you've kept. Answer the questions below and we'll work out your personal day budget under the Statutory Residence Test, and show you what would raise it.

1 Your situation
? What this means

A UK tax year runs from 6 April to 5 April the following year, not January to December. So 2026/27 means 6 April 2026 to 5 April 2027.

Your allowance applies per tax year, and it can change from one year to the next as ties fall away. The second year abroad is usually more generous than the first.

Where are you in the move?
Were you UK tax resident in any of the last three tax years?
? What this means

For 2026/27, the last three tax years are 2023/24, 2024/25 and 2025/26. If you were living and paying tax in the UK during any of them, answer yes.

It matters a lot here: recent leavers work from a tighter table and face an extra tie (the country tie), so the same ties buy fewer days.

If you were living in the UK until recently, that's a yes.

2 Work
? What counts as a work day

More than 3 hours of work in a day makes it a work day, and it doesn't need to be in an office. Emails at your mum's kitchen table, a client call, a site visit: three hours and one minute is enough.

Two thresholds matter for your allowance: 40 or more work days gives you the work tie (costing you a band), and 31 or more closes the generous full-time-work-abroad route.

Office days, client meetings, even a solid session on the laptop while visiting family.

Will you work full time overseas across the year? Roughly 35+ hours a week abroad, without a break of a month or more.
? Why this can raise your allowance

Full-time work overseas is its own route to automatic non-residence, worth up to 90 UK days almost regardless of ties, as long as your UK work days stay under 31.

"Sufficient hours" means broadly an average of 35 or more a week across the year, employed or self-employed, and a break of 31 days or more (ignoring leave) fails it. A normal full-time job in Dubai passes comfortably.

Will you work full time in the UK across the year?
? What this means

This catches people whose working life genuinely stays in the UK: sufficient hours worked here over a 365-day stretch, with most working days in the UK. It makes you resident whatever your day count, so there's no allowance to calculate. If you're moving your work to the UAE, this won't be you.

3 Homes
Will you have a home of your own in the UK, owned or rented, through a stretch of 91 days or more?
? What counts as a home

A "home" is somewhere you actually live: owned, rented, or even rent-free, furnished and there for you to live in. A property you've let to tenants on a proper tenancy isn't available for you to live in, so it doesn't count here.

We ask because a UK home you keep using can trigger an automatic residence test that no day allowance survives. The next two questions check whether that trap is armed.

Will you have a home outside the UK, your place in Dubai say, where you're present on 30 or more days?
? Why this helps you

This is usually your escape route. If you're present in a home outside the UK on 30 or more days in the year, the UK home test can't make you automatically resident, whatever you keep here. Your ties still set the allowance, but the trap is off.

Is there anywhere in the UK available for you to stay for 91 days or more in a row? Your own place, a property you've kept, or a family home where there's always a bed for you.
? What counts as available

This is broader than a home you own. Anywhere available for you to stay for 91 days or more in a row counts: the house you kept, a family home where there's always a bed, a friend's place you can genuinely use whenever you like. Short gaps in availability (under 16 days) don't break the chain.

A hotel you book as and when you need it doesn't normally count.

This is the "accommodation tie", and releasing it is one of the quickest ways to raise your allowance.

4 Family
Will your husband, wife, civil partner, or a partner you live with be UK resident this year? Ignore this if you're separated.
? Who counts

A husband, wife, civil partner, or someone you live with as a couple, who will themselves be UK tax resident for the year. Separated (by court order, deed, or in circumstances likely to be permanent) means they don't count.

If your partner is moving out with you, whether they count depends on their own residence position for the year. That's one of the fiddlier corners of the test and worth checking properly.

Do you have children under 18 who'll be UK resident?
? The boarding school detail

This means a child under 18 who is UK resident in their own right. One useful carve-out: a child who is only in the UK for full-time education and spends fewer than 21 days here outside term time can be disregarded.

If your children are at school in the UK while you're in Dubai, that detail is worth checking properly. It changes the answer for a lot of families.

5 Recent history
Did you spend more than 90 days in the UK in either of the last two tax years?
? Which years those are

Planning 2026/27? Then this asks about 2024/25 (6 April 2024 to 5 April 2025) and 2025/26 (6 April 2025 to 5 April 2026). More than 90 days in the UK in either one gives you the tie.

If you were living in the UK through those years, it's automatically a yes. You can't change this tie for this year, but a year at 90 days or fewer sheds it for the next.

If you were living here, that's a yes.

This calculator reads the Statutory Residence Test's sufficient ties table backwards: given your ties, it shows the most UK days you can spend before tipping into residence, alongside the automatic tests that can override it. It is a guide, not a formal HMRC determination or personal advice, and it does not model split-year treatment, the deeming rule day-by-day, or exceptional-circumstances days. Checked against HMRC's current guidance (the RFIG20000 manual series, formerly RDR3) on 17 July 2026.

How the allowance works

People talk about "the 90-day rule" as if it were universal. It isn't. The Statutory Residence Test sets your personal limit by counting the ties you've kept to the UK: family here, somewhere to stay, 40 or more work days, a recent history of UK time and, for recent leavers, where your nights land. Keep four ties and your allowance can be as low as 15 days; keep none and it stretches to 182. The 183-day figure everyone quotes is just the hard ceiling above which residence is automatic.

The useful part is that the ladder works in both directions. Each tie you release moves you up a band, and some ties are easier to release than people think: staying in hotels rather than the old flat, keeping UK work under 40 days, or simply getting one full year abroad behind you. This calculator shows your number and exactly which lever would change it.

Common questions

Is there a single number of days everyone can spend in the UK?

No, and anyone quoting "90 days" as a universal rule is oversimplifying. Your allowance depends on the ties you keep: family, accommodation, work, your recent UK history and, for recent leavers, where you spend the most nights. It ranges from 15 days to 182 depending on your circumstances.

How are the days counted?

Broadly, a day counts if you are in the UK at midnight. The day you arrive usually counts, the day you fly home usually does not. Frequent same-day visits can also start to count under a deeming rule if you keep three or more ties.

Can I increase my allowance?

Often, yes. Each tie you release moves you up a band: letting a property go, keeping UK work days under 40, or simply getting a full year abroad behind you (which sheds the 90-day tie). Working full time overseas can also give you up to 90 days almost regardless of ties. This is exactly the planning a good adviser earns their fee on.

Is this the same as the 183-day rule?

The 183-day rule is just the ceiling: at 183 days you are automatically UK resident, whatever your ties. Most leavers hit trouble far below that, because the ties test tightens the limit to 120, 90, 45 or even 15 days. This calculator tells you which of those limits is yours.
