What is Accidental landlord?
Last verified 31 October 2026
An accidental landlord is someone who becomes a landlord without planning to, for example after inheriting a property, moving for work and renting out their old home, or being unable to sell. The duties are the same as for any landlord.
Why it matters to landlords
Once rent is paid, it is income that normally goes on a Self Assessment return. GOV.UK says you must tell HMRC by 5 October after the tax year if you need to file a return and have not sent one before. Rental income of £1,000 or less may be covered by the property allowance, and above that you can deduct either your actual expenses or the allowance, not both.
In England, landlords of occupied properties on assured or regulated tenancies must register on the PRS database. GOV.UK says registration rolls out region by region from 15 December 2026 and all landlords must be registered from 15 November 2027. Selling later brings Capital Gains Tax questions: GOV.UK says it may apply to the profit on inherited property, with most UK property sales reported and paid within 60 days. Check your mortgage and insurance as well.
Example
Lena moves abroad for work in 2026 and lets her flat for £900 a month. She received £5,400 by the end of the tax year, so she tells HMRC by 5 October 2027 that she needs a return, lists the rent on it and deducts her allowable costs.
