Checked against GOV.UK and HMRC sources on August 1, 2026.
The UK SRT country tie is a comparison test.
HMRC says the country tie applies for a tax year if the UK is the country where you were present at midnight for the greatest number of days in that tax year. If two or more countries tie for the greatest number of midnight days, and the UK is one of them, HMRC says you have a UK country tie for that year.
Short answer: do not track UK days in isolation. Track midnight days in the UK and compare them with midnight days in every other country during the same UK tax year.

What is the UK SRT country tie?
The country tie is one of the ties used inside the UK's Statutory Residence Test.
HMRC's country-tie manual says an individual has a country tie if the UK is the country in which they were present at midnight for the greatest number of days in the tax year.
That wording makes the recordkeeping problem clear. You need more than a UK total. You need a country-by-country comparison.
The UK tax year runs from 6 April to 5 April. So the question is not "where did I spend the most days this calendar year?" It is "where was I present at midnight most often during the UK tax year?"
Does the country tie decide UK tax residence by itself?
No.
GOV.UK says UK residence usually depends on days in the UK during the tax year, but the final status turns on the automatic UK tests, the sufficient ties test, and whether any automatic overseas test applies.
That means the country tie is one fact inside the wider SRT analysis. It is not a shortcut answer.
Keep the distinction clean:
| Question | What it answers |
|---|---|
| UK day count | How many UK days you had in the tax year |
| Country tie | Whether the UK had the greatest number of midnight days compared with other countries |
| Sufficient ties test | How your ties and UK days interact |
| Automatic tests | Whether automatic UK or overseas tests settle the result |
If you are close enough to care about the country tie, you are close enough to keep the full record for a tax professional.
How do you count days for the country tie?
HMRC's day-counting manual says a person is generally treated as spending a day in the UK if they are in the UK at the end of the day, meaning midnight.
The manual also points to exceptions and adjustments, including deeming rules, transit days, and exceptional-circumstances rules.
For the country tie, start with a country-by-country midnight log:
- UK midnight dates
- non-UK country midnight dates
- travel dates where midnight happened in transit
- arrival and departure proof
- notes for transit, deeming, or exceptional-circumstance questions
- adviser notes on how each edge case was treated
Do not round a travel pattern from memory. Midnight rules punish fuzzy records.
What happens if the UK ties with another country?
HMRC says the UK country tie can still apply if the greatest number of midnight-presence days is the same for two or more countries and one of those countries is the UK.
That is the part many people miss.
Example pattern:
| Country | Midnight days in UK tax year |
|---|---|
| United Kingdom | 72 |
| Portugal | 72 |
| United Arab Emirates | 68 |
If the UK and Portugal tie for the greatest number, the UK can still create the country tie under HMRC's stated rule.
This example is only a recordkeeping illustration. It does not decide anyone's tax residence.
Why does this differ from the 90-day tie?
The 90-day tie and country tie are different SRT concepts.
The country tie compares the UK with other countries in the tax year being checked. The 90-day tie looks back at UK days in earlier tax years.
For tracking, that means you need two kinds of history:
- current UK tax-year midnight days by country
- prior-year UK presence history for the separate 90-day tie
Mixing these together creates bad records. Keep separate notes for each tie.
What should returning UK leavers track?
The country tie is especially easy to miss when someone leaves the UK but still spends the largest share of their year there.
Track:
- every UK midnight
- every midnight in the main country where you now live
- every midnight in third countries
- UK workdays if work ties may matter
- UK accommodation nights if accommodation ties may matter
- family or home facts requested by your adviser
- SRT source links used for the year
The point is not to self-diagnose from a table. The point is to make the table trustworthy.
What should digital nomads track?
Digital nomads often move through many countries without noticing which one has the highest midnight total.
That creates a practical problem. The UK may not feel like your main country, but it can still be the country with the greatest number of midnight days if every other country total is fragmented.
A cleaner record answers:
- Which country has the highest midnight total?
- Does the UK tie with that country?
- Which UK tax year are you checking?
- Did any UK days need transit, deeming, or exceptional-circumstance review?
- Which SRT ties are being reviewed separately?
If the answer changes by one or two days, keep the proof close.
