UK rental deadlines for a landlord living abroad
The operational dates behind registration, paper returns and electronic filing.
Direct answer
A new Self Assessment obligation can require registration by 5 October after the relevant tax year. Paper returns are generally due earlier than compatible electronic filings; the current GOV.UK page should control the exact date.
Working route
Register if needed
If you do not already file, determine whether the rental level and circumstances require Self Assessment registration.
Choose the filing channel early
The non-resident residence pages may require post, compatible commercial software or an adviser rather than the ordinary HMRC online service.
Reconcile withheld tax
Collect the agent or tenant certificate so tax deducted under NRLS can be credited in the annual calculation.
Hard stop
A late return, missing UTR, sale of UK property or split-year residence needs a separate deadline plan.
