Tax filing calendar
The key UK dates an overseas landlord must not miss — Self Assessment, the 60-day CGT report, ATED, and the new Making Tax Digital quarterly updates.
Who it applies to
Any overseas investor with UK rental income or a UK property disposal.
How it affects your return
Missing a deadline means automatic penalties and interest. The main dates: register for Self Assessment by 5 October after your first year of rental income; online tax return and payment by 31 January; CGT on a property sale reported and paid within 60 days of completion; ATED returns by 30 April. From 6 April 2026, landlords with qualifying income of £50,000+ must also keep digital records and file quarterly updates under Making Tax Digital for Income Tax.
Common mistakes
- Registering late for Self Assessment in your first rental year.
- Treating the 60-day CGT report as part of the annual return — it is separate and much sooner.
- Being caught unprepared for MTD quarterly filing if income is £50k+.
Investor action checklist
- Register for Self Assessment by 5 October after your first rental year.
- File and pay online by 31 January; budget for payments on account.
- Report any property sale within 60 days; file ATED by 30 April if a company holds it.
- Set up MTD-compatible software if qualifying income is £50k+.
