How the Rent a Room Scheme works

You can earn up to £7,500 a year tax-free from letting furnished accommodation in your only or main home, for example to a lodger or as a holiday let while you live there. It halves to £3,750 if someone else, like a joint owner, also gets income from letting in the same home. Under the limit it's automatic. Over it, you must send a tax return, and you can choose to pay tax on either your receipts minus the £7,500 (with no expenses), or your actual profit.

When it doesn't apply

  • The room isn't in your main home when you let it, or you let your home while you live abroad.
  • The accommodation isn't furnished.
  • It's used as an office or for business (a lodger working there in the evenings, or a student studying, is fine).
  • Letting a whole separate property: use the normal property rules instead.

Worked examples

1. Lodger, £6,000 a year: Under £7,500, so it's tax-free: £0.00.

2. Lodger, £9,000 rent, £1,500 costs: The allowance gives £1,500 taxable, actual profit would be £7,500, so the allowance wins: £300.00 tax at 20%.

3. Big costs, £9,000 rent and £8,500 costs: Actual profit is £500, lower than the £1,500 the allowance would leave, so actual profit is used: £100.00 tax.

Frequently asked questions

How much can I earn tax-free renting a room?

Up to £7,500 a year under the Rent a Room Scheme, or £3,750 if the income is shared with someone else letting in the same home.

Do I need to tell HMRC about a lodger?

Not if your receipts are £7,500 or less (or £3,750 shared): the exemption is automatic. Over that, you must send a tax return.

Can I use Rent a Room for Airbnb?

Yes, if you let furnished accommodation in your only or main home. It doesn't cover a separate property you don't live in.

Can I claim expenses as well?

Not with the allowance. Over the limit you choose either receipts minus £7,500, or receipts minus actual expenses.
