Do I need a UK tax return if I am non-resident?
When non-residents may still need Self Assessment and the SA109 residence pages.
Short answer: You may. Non-residence does not automatically remove Self Assessment. UK rental income, self-employment, certain gains, untaxed income or an HMRC notice to file can require action. If you claim non-residence or split-year treatment in a return, the SA109 residence pages are normally needed and cannot generally be filed through HMRC’s basic online service.
Key points
- Do not ignore an HMRC notice to file.
- UK income can create a return requirement.
- Residence claims need supporting facts and records.
- Property-sale reporting may be due before the annual return.
Common reasons to file
The answer depends on the type and amount of UK income, tax already deducted and any claims required. A return may also be useful to reconcile Non-Resident Landlord deductions or claim relief.
- UK rental profit
- UK self-employment
- Untaxed UK income
- Residence, split-year or treaty claims
- An HMRC notice requiring a return
Residence pages
SA109 records days, ties, residence status, domicile-related information and split-year claims. The conclusions should match your travel and work evidence.
Separate property deadlines
A non-resident selling UK land or property may need a 60-day disposal report even if a Self Assessment return will also be filed later.
