The UK Rent a Room Relief (also known as the Rent a Room Scheme) lets homeowners and tenants earn up to £7,500 per year in rental income from renting furnished rooms in their own home, completely tax-free. This applies to lodgers, long-term housemates, and short-term rentals like Airbnb guests — provided you live in the property at the same time. If you earn below the threshold, no reporting is needed. If you earn above it, you choose whether to use the scheme (paying tax only on the excess) or opt out and deduct actual expenses.
Quick answer: Rent a room in your own home — first £7,500 of gross income is tax-free automatically. No need to tell HMRC if income is under £7,500. If over £7,500, pay tax on the excess (gross income minus £7,500) OR opt out and use normal landlord rules (income minus actual expenses). PRR exemption on eventual home sale is NOT affected by renting a room.
Rent a Room Relief: Key Facts 2026
| Feature | Detail |
|---|---|
| Annual threshold | £7,500 gross rental income per year |
| Joint ownership threshold | £3,750 each (total still £7,500) |
| Applies to | Furnished rooms in your main home (where you live) |
| Automatic? | Yes — applies automatically if income ≤ £7,500 |
| Tax on income above threshold (scheme) | Gross income − £7,500 = taxable amount (no expenses deducted) |
| Alternative | Opt out: income − actual expenses = taxable (standard landlord rules) |
| CGT on eventual home sale | Not affected — PRR exemption preserved |
Who Qualifies for Rent a Room Relief
You qualify if:
- You rent out a furnished room (or rooms) in your main home — the property where you normally live
- You are the owner OR a tenant of the property (you can sublet if your tenancy allows it)
- The room is let to a lodger, housemate, or short-term guest
You do NOT qualify if:
- You rent out a property where you do not live (standard buy-to-let rental income)
- You rent out an unfurnished room
- You operate a bed and breakfast or guest house at a separate address
- The rental is a commercial letting (not residential)
Airbnb and short-term rentals: If you rent rooms in your own home via Airbnb or similar platforms while you continue to live there, the income qualifies for the Rent a Room Scheme. If you rent the entire house while you are away, it may not qualify (you are not living there during that period).
How the Scheme Works Below £7,500
If your gross rental income from renting rooms in your home is £7,500 or less in a tax year:
- The income is automatically tax-free
- You do not need to tell HMRC
- You do not need to file a Self Assessment return for this income alone
- You cannot deduct any expenses (the threshold replaces expenses)
This makes it extremely simple for casual room renters — no bookkeeping, no return, no tax.
If Your Income Exceeds £7,500
You must register for Self Assessment and declare the income. You then have two options:
Option 1: Stay in the Scheme
Pay income tax only on the amount above the threshold:
$$ ext{Taxable Amount} = ext{Gross Rental Income} - \pounds7,500$$
Example: Gross rental income = £10,000 Taxable: £10,000 − £7,500 = £2,500 Tax at 20%: £500
You cannot deduct actual expenses under this option.
Option 2: Opt Out — Use Normal Landlord Rules
Report gross rental income and deduct actual allowable expenses:
$$ ext{Taxable Amount} = ext{Gross Rental Income} - ext{Allowable Expenses}$$
Example: Gross rental income = £10,000, expenses = £4,000 Taxable: £10,000 − £4,000 = £6,000 Tax at 20%: £1,200
In this example, staying in the scheme (Option 1: £500 tax) is better. But if expenses were £9,000, opting out (£200 tax) would be cheaper.
When to opt out: When your actual allowable expenses exceed the £7,500 threshold — typically only if you have very high expenses relative to rent charged.
To opt out, tick the relevant box on your Self Assessment return and submit full landlord accounts instead.
Rent a Room and Capital Gains Tax
One of the most important advantages of the Rent a Room Scheme over standard buy-to-let landlord accounting: it does not affect your Principal Private Residence (PPR) relief on Capital Gains Tax when you sell your home.
If you rent rooms in your home while continuing to live there, your full PRR exemption still applies. The entire gain on the eventual sale of your home may remain free of CGT — provided the ordinary PPR conditions are met (you lived there as your main home throughout).
This contrasts with standard buy-to-let where claiming Capital Allowances (depreciation equivalent) on the property can affect the PRR calculation.
Rent a Room and the Property Income Allowance
Note: The Property Income Allowance of £1,000 is a separate relief that applies to rental income from properties where you do not live. You cannot use both the Rent a Room threshold (£7,500) and the Property Income Allowance for the same income. If you rent rooms in your home, use the Rent a Room Scheme — it is far more generous.
Joint Ownership
If you own the property jointly (e.g., with a spouse or partner), the threshold is halved:
- Each joint owner can claim £3,750 — the total tax-free amount is still £7,500
- Both owners must elect to use the scheme if income exceeds £7,500
Practical Tips for Lodger Landlords
- Keep a record of income: Even if below £7,500, keep a simple record in case HMRC asks questions
- Lodger vs tenant: A lodger (sharing your home) has fewer legal rights than a tenant with exclusive use of a property — this affects deposit rules and notice periods
- Check your mortgage/lease: Your mortgage lender or landlord may need to approve letting rooms — check your terms
- Insurance: Notify your home insurer that you have a lodger — failure to disclose may invalidate your cover
- Universal Credit: Rent a Room income may affect means-tested benefits — check with the relevant department if you receive Universal Credit or Housing Benefit

The Rent a Room Scheme is one of the most underused tax reliefs in the UK. For anyone renting a room to a lodger or short-term guest in their primary home, the £7,500 tax-free threshold provides a meaningful income stream with virtually no tax compliance requirement. Even above the threshold, the scheme usually produces a lower tax bill than deducting actual expenses — check both options before filing.
