Living abroad does not automatically end your UK tax obligations. UK rent or untaxed income may still require a Self Assessment return. However, non-residence alone does not mean everyone must file annually.
The key is separating three questions: where are you tax-resident, what income is taxable, and does HMRC require a return?
Check Your Residence Status First
An overseas address is not proof of non-residence. The Statutory Residence Test considers UK days, work, homes and family ties; spending fewer than 183 days here does not automatically make you non-resident.
If you left partway through the year, split-year treatment may apply, but it is not automatic. Keep travel records and details of UK workdays rather than relying on your departure date alone.
When Is a Return Needed?
For landlords, tax deducted is not necessarily tax settled. Under the Non-Resident Landlord Scheme, deductions by an agent or tenant are credited against your liability. HMRC approval to receive rent gross removes withholding, not the underlying tax or return obligation.
Avoid These Costly Mistakes
- Assuming the Personal Allowance is automatic. The standard allowance is £12,570 for 2025/26 and 2026/27, but non-resident eligibility depends on nationality, treaty provisions or other qualifying circumstances; higher income can reduce it.
- Paying twice without checking relief. Your country of residence may also tax UK income. Treaty relief may be available, but the agreement determines where and how to claim.
- Waiting until January after selling property. Non-resident individuals generally must report UK property or land disposals within 60 days of completion, even with a loss or no tax due. This is separate from annual Self Assessment.
Filing and Deadlines
Non-resident returns normally require SA100 and residence pages SA109, plus relevant income schedules, such as SA105 for property. HMRC’s standard online filing service does not support non-resident returns; use suitable commercial software, an accountant or paper forms.
For 2025/26, the usual deadlines are:
- 5 October 2026: Notify HMRC if newly required to file
- 31 October 2026: Paper return reaches HMRC
- 31 January 2027: Electronic filing and balancing tax payment
- 31 July 2027: Second payment on account, if applicable
The paper deadline has passed, but electronic filing may still be available. Different deadlines can apply to late-issued notices. Late filing normally starts with a £100 penalty; further penalties and late-payment interest can follow.
SA109 filers can be exempt from Making Tax Digital for 2026/27. From April 2027, affected landlords and sole traders with 2025/26 qualifying income above £30,000 before expenses may need to join, subject to exemptions.

FAQs:
Must I report my overseas salary?
Generally not if you are genuinely non-UK resident. However, earnings for UK workdays and your departure year need separate review.
Does income below £12,570 mean no return?
No. Allowance eligibility and filing obligations are separate; an outstanding HMRC notice still requires action.
Does form P85 replace a tax return?
No. P85 may suit some departures, but it does not replace a required Self Assessment return.
Can I simply stop filing after leaving?
No. Ask HMRC to close your Self Assessment record where appropriate, and obtain withdrawal of any unnecessary notice to file.
