Leaving the UK Tax 2026/27 — Residence & Split Year

Leaving the UK does not automatically change your tax status — HMRC applies the Statutory Residence Test (SRT) to each tax year, and a treaty with the new country can create a separate residence question. For 2026/27, the automatic overseas tests, automatic UK tests and sufficient-ties test determine domestic UK residence. Split-year treatment can divide a year into UK and overseas parts only when one of the statutory cases and all its conditions apply; it is not a general departure-date election. Model your position with the Salary Calculator→ and read the Working Abroad and Double Taxation guide for treaty relief.

The three questions that matter are: how many days do you spend in the UK, do you work abroad full-time, and what UK ties do you keep? A family home, a spouse in the UK, or a UK job can keep you resident even if you live abroad most of the year.

The Statutory Residence Test — Stage by Stage

The SRT is applied using the statutory tests and your facts for the year. The automatic overseas tests include the 16-day test where you were UK resident in one or more of the previous 3 tax years, the 46-day test for someone not resident in any of those 3 years who works full-time abroad, and the full-time-work-abroad test for someone with a relevant history of UK residence. The automatic UK tests include 183 days or more in the UK, a UK home test, and a full-time work test. If no automatic test decides the result, the sufficient-ties test considers family, accommodation, work, 90-day and country ties.

The table is only the sufficient-ties stage and does not replace the automatic tests. If you were not resident in any of the previous 3 tax years, a different table applies. The detailed SRT guidance also defines the special rules for a leaver and the meaning of each tie.

A leaver who keeps a UK home and family connections may have multiple ties, but residence still depends on the applicable table, the automatic tests and the precise facts. Selling a home or moving family members does not by itself determine the result.

Split-Year Treatment

The UK tax year runs 6 April to 5 April. Split-year treatment is available through eight statutory cases: three concern departure and five concern arrival. Each case has its own conditions and priority rules. If a departure case applies, the year is divided into a UK part and an overseas part, but the tax treatment of income and gains still depends on the type of income, the source, treaty rules and the case. Record the relevant facts and report the position on Self Assessment where a return is required; do not assume that a departure date or a generic claim creates split-year treatment.

What UK Income Is Still Taxed

Non-residents can remain liable to UK tax on UK property income and gains. The Non-Resident Landlord Scheme may require a letting agent or tenant to withhold tax unless HMRC approves gross payment; gross-payment approval does not remove the underlying tax or filing obligations. Check the property, gain, relief and treaty rules rather than applying a single rate or allowance to every case.

The Exit Charge and Temporary Non-Residence

Temporary non-residence is not a blanket exit charge. The rules can apply when, among other conditions, you had sole UK residence in at least 4 of the 7 tax years before departure and the relevant non-residence period lasts 5 years or less. They can bring specified income and gains received or remitted during the absence into charge in the year of return. The detailed rules contain exclusions and are not limited simply to assets held before departure, so review the exact asset and income category before timing a disposal.

Domicile and the New FIG Regime

For Inheritance Tax, the post-6 April 2025 framework uses long-term UK residence, not the old domicile-based worldwide-estate test. A person is generally long-term UK resident after UK residence in 10 of the previous 20 tax years, and a former long-term resident can remain in scope for a period of 3 to 10 tax years after leaving depending on their history. The Foreign Income and Gains regime is mainly relevant to qualifying new arrivals and does not make a leaver's foreign income automatically exempt. Consider SRT, treaty, temporary non-residence and IHT separately.

Practical Steps Before You Go

Tell HMRC about your departure using the route that applies to you, including P85 where appropriate. P85 does not replace the SRT analysis or treaty review. Report split-year treatment and UK-source income through Self Assessment where required. Do not cancel a personal allowance automatically: eligibility depends on residence, nationality and treaty provisions. You can generally keep an existing ISA, but ISA subscriptions and pension-relief rules after departure have conditions. Keep a detailed travel and work diary and evidence of homes, ties and employment for the relevant years.

Common Mistakes When Leaving

• Assuming residency ends on the flight date — the SRT assesses the whole tax year.
• Keeping a UK home — the accommodation tie alone can keep you resident on far fewer days.
• Not claiming split-year treatment — the default is full-year residence.
• Selling assets before planning the return — the five-year temporary non-residence rule can tax the gain.
• Forgetting the NRL scheme — UK rental income must be handled correctly from day one.

Frequently Asked Questions

Reviewing the first full year overseas

At the end of the departure year, compare the residence analysis with actual travel and work records. Check whether extra UK days, an available home, a UK workday or a family tie changed the result. A split-year claim is not an automatic consequence of selling a home or starting a foreign job; the relevant case and conditions must be established.

Reconcile every UK-source amount to the return: rent, employment, directorships, pension, bank interest and disposals. Keep foreign tax certificates and the exchange-rate method used. A treaty may allocate taxing rights differently from domestic law, and relief may require a claim. Do not remove UK income from a return because tax was paid overseas.

Review PAYE, National Insurance, pension contributions, social-security treatment and employer reporting separately. If the person returns to the UK or works in several countries, start a new residence and payroll review rather than extending the original conclusion without checking the new facts.

Residence and source should be reviewed again if the person returns, works temporarily in the UK, sells a UK asset or changes the destination country.

A departure-year file prevents most surprises

Create a departure-year file with the exact date you left, days spent in the UK, available accommodation, workdays, family links and the date each home was available. Keep travel evidence, tenancy or sale documents, employment contracts, board minutes and business records. Residence is assessed under the statutory residence test, and a simple count of days or the address on a tax return is not enough.

Separate UK-source income from overseas income after departure. Salary, directorships, rent, pensions, interest and gains can have different source and reporting rules. Record the currency conversion method and the tax paid abroad, but do not assume a foreign tax credit is automatic; double-tax agreements and domestic relief rules can limit the amount. A new country may also tax income that remains outside UK tax.

Notify employers, pension providers, banks and HMRC when the facts require it, and review PAYE codes after the move. Keep evidence for the split year claim and for any later return. If a property is retained in the UK, review rent, agent, mortgage and disposal consequences separately. Leaving the country changes the fact pattern; it does not by itself end every UK filing obligation.

Reconcile Residence with the First Overseas Return

The departure analysis should be reopened after the tax year closes. Compare the planned departure date with actual UK days, workdays, available accommodation and family ties, then check the split-year case against the facts that occurred. A late visit, an unexpected UK workday or a home becoming available can change the residence result. Keep the original analysis, the updated facts and the reason for any conclusion change rather than overwriting the file.

Separate residence from source. UK rent, directorship income, pension payments, interest and property gains can continue after departure even when the individual is non-resident. Reconcile each amount to the relevant return, withholding record, treaty position and foreign-tax evidence. A P85, Non-Resident Landlord approval or PAYE code change can support administration, but none of them independently proves statutory residence or eliminates a filing obligation.

If a return to the UK is possible, mark the departure date, return date and non-residence period for the temporary non-residence review. Check whether the relevant four-out-of-seven and five-year conditions apply to the specific income or gain. The safest record is a dated timeline linking travel, work, home availability, asset transactions and filings; it is more reliable than a general statement that the person “moved abroad”.
