Why it matters
What Rent a Room Relief means for a landlord
Rent a Room is the most generous everyday tax break in residential letting, but it is easy to misapply. It only covers a room in the home you actually live in, so it does not apply to a whole property let out or to a home you have moved out of. If your rent-a-room income exceeds £7,500 you can either pay tax on the excess above the threshold or on the profit after actual expenses, whichever is lower. A lodger under this scheme is an excluded occupier, not an assured tenant, so the Renters’ Rights Act possession rules do not apply.
Worked example
How it plays out
Sam lets a furnished room in his home in York to a lodger for £600 a month, £7,200 a year. That is under £7,500, so it is tax-free under the Rent a Room scheme. If the rent rose to £700 a month, £8,400 a year, he could pay tax on the £900 above the threshold or on his actual profit after expenses, whichever is lower.
Common mistakes
Where landlords go wrong
- 01Using the scheme for a self-contained flat or a home you do not live in.
- 02Forgetting the limit halves when someone else also receives income from the letting.
- 03Treating a lodger as a tenant, or the other way round.
What to do
A short checklist
- Check the room is furnished and in your main home.
- Track the rent against the £7,500 limit.
- Choose the better tax method if you go over it.
