UK day-count analysis
Travel records are converted into the statutory UK-day count, including consideration of relevant deeming rules where necessary.
UK tax residence is determined tax year by tax year under the Statutory Residence Test. Day counts matter, but so can overseas work, UK homes, family connections, previous residence and the number of days on which an individual works in the UK.
We do not determine residence by nationality, immigration status or where someone considers their permanent home to be. The analysis starts with the statutory tests and then considers split-year treatment, treaty residence and the tax consequences that follow from the result.
Approximate dates are sufficient for the first enquiry. Detailed travel records can follow through secure onboarding.

The residence position should be determined before deciding how foreign income, employment earnings or gains are taxed in the UK.
An individual can spend fewer than 183 days in the UK and still be UK resident. Conversely, spending significant time here does not mean every person uses the same day threshold because previous residence and UK ties can alter the sufficient-ties calculation.
The engagement can be prospective before a move or retrospective when a residence position needs to be reported on a tax return or checked after HMRC correspondence.
Travel records are converted into the statutory UK-day count, including consideration of relevant deeming rules where necessary.
Automatic overseas tests, automatic UK tests and the sufficient-ties test are applied in the correct sequence.
Arrival and departure circumstances are tested against the statutory split-year cases and priority rules.
UK workdays, overseas work and full-time employment conditions are reviewed where they affect residence or split-year treatment.
Where two countries treat the individual as resident, the relevant double tax treaty may require a separate treaty-residence analysis.
Residence, split-year and relevant international claims are reflected consistently in the Self Assessment residence pages.
Residence advice is built from the chronology first, then the statutory tests, before the wider income and gains consequences are considered.
Arrival, departure, travel days, workdays, homes and relevant family circumstances are established.
The automatic overseas, automatic UK and sufficient-ties tests are considered in statutory order.
Where the individual is resident for the year, the relevant arrival or departure split-year cases are reviewed.
Residence is then connected to foreign income, employment, gains, treaty relief and the required tax-return reporting.
Residence is not determined by selecting the test that produces the preferred answer. The automatic overseas tests are considered first, followed by the automatic UK tests and then the sufficient-ties test where necessary.
A UK day count should be supported by evidence such as travel records, passport information, calendars and work records where available. For internationally mobile employees, counting UK workdays separately from UK presence days is often necessary.
HMRC's current RDR3 guidance covers the automatic overseas tests, automatic UK tests, sufficient ties and split years.
Official SRT guidance ↗Current GOV.UK guidance explains the relationship between UK residence and taxation of foreign income.
Residence guidance ↗The SRT normally determines residence for the whole tax year. Split-year treatment then modifies the tax treatment for qualifying arrival and departure circumstances.
The split date is not necessarily the date of the aeroplane ticket or removal van. Depending on the applicable case, it may be linked to starting or ceasing full-time work, a change in homes or another statutory event.
Residence determines the framework; foreign income, employment, pensions and historic offshore reporting then need their own tax analysis.
Residence depends on the whole tax year and prior residence history, so a single day-count figure is rarely enough for a complex case.
Yes. Spending 183 days or more in the UK during the tax year meets an automatic UK residence test.
Yes. Other automatic UK tests or the sufficient-ties test can make an individual UK resident with a lower day count.
No. Immigration status and tax residence are separate legal concepts. UK tax residence is determined under the Statutory Residence Test.
Potentially. You must first be UK resident for the tax year and then satisfy one of the statutory split-year cases. If the conditions are met, split-year treatment applies.
No. The split date depends on the statutory case that applies and can be linked to employment, homes or other conditions rather than simply the date you physically moved.
Yes under the domestic laws of both countries. Where a double taxation agreement applies, its residence article may then determine treaty residence for treaty purposes.
Residence and split-year positions are normally reported through the residence supplementary pages where a Self Assessment return is required.
Yes where possible. Workdays, homes, family ties and UK presence can all affect the result, so prospective planning is often more useful than reconstructing the position after the tax year has ended.
