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.

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.
