Renting a Room on Airbnb — Rent-a-Room Scheme Explained

The Accounted Business Team·3 March 2026·9 min read

Airbnb has turned spare rooms into income streams for hundreds of thousands of UK homeowners. Whether you are hosting the occasional weekend guest or running a more regular operation, renting a room in your home can bring in a surprisingly handy sum — and thanks to the Rent-a-Room scheme, a generous chunk of it can be completely tax-free.

But the rules are not always as simple as they first appear. The scheme has specific conditions, and getting them wrong could mean paying more tax than necessary — or worse, not paying enough. Let us walk through exactly how it all works.

What Is the Rent-a-Room Scheme?

The Rent-a-Room scheme is a government tax relief that allows you to earn up to £7,500 per tax year from letting a furnished room (or rooms) in your main home, completely tax-free. You do not need to apply for it — it is automatic.

This is significantly more generous than the standard £1,000 property allowance, which is why it is so popular with Airbnb hosts, lodger landlords, and anyone renting out a spare room.

Key conditions

To qualify for Rent-a-Room relief, the following must be true:

It must be your main home. You cannot use the scheme for a second property, holiday home, or buy-to-let.
The room must be furnished. Renting out an empty room does not qualify.
You must be renting a room, not a whole property. If you let out your entire home while you are away (for example, renting your flat on Airbnb while you are on holiday), the scheme does not apply.
The income must come from residential use. Letting a room as an office or workshop does not count.

If you share ownership of the property with someone else (for example, a partner or spouse) and you both receive rental income, the £7,500 threshold is halved — you each get £3,750.

How Does It Work With Airbnb?

Airbnb hosting fits neatly within the Rent-a-Room scheme, provided you are renting a room in your main home — not the whole property.

Here is how it plays out in practice:

Scenario 1: Income under £7,500

You host Airbnb guests in your spare room and earn £5,000 over the tax year. Under the Rent-a-Room scheme, this is entirely tax-free. You do not need to declare it to HMRC or file a Self Assessment tax return (unless you already file one for another reason).

Scenario 2: Income over £7,500

You are a popular host and earn £10,000 from your Airbnb room over the year. You have two options:

Option A — Use Rent-a-Room relief: Deduct the £7,500 allowance from your gross income. Taxable amount = £10,000 – £7,500 = £2,500. You pay tax on £2,500.

Option B — Claim actual expenses: If your expenses (cleaning, laundry, a share of utilities, Airbnb service fees, etc.) exceed £7,500, it might be more tax-efficient to opt out of the Rent-a-Room scheme and instead claim actual expenses against your rental income.

In most cases, Option A is better because £7,500 is a generous allowance. But if you have spent heavily on furnishing the room, buying new bedding, or making improvements, it is worth running the numbers both ways.

Scenario 3: Renting your whole property

You go on a two-week holiday and let your entire flat on Airbnb while you are away, earning £1,500. Because you are letting the whole property (not just a room), the Rent-a-Room scheme does not apply.

Instead, this is treated as standard property income. You can use the £1,000 property allowance, or claim actual expenses against the income. You would need to declare it on a Self Assessment if your total property income exceeds £1,000.

What Counts as Income?

Your Rent-a-Room income includes everything you receive from guests, including:

The nightly room rate
Cleaning fees you charge
Any other charges (late checkout, extra guests, etc.)

It does not include the Airbnb service fee — that is deducted by Airbnb before you receive payment, so it never forms part of your income.

However, if guests pay you directly for extras (meals, laundry, experiences), those amounts do count towards your £7,500 threshold.

Expenses You Can Claim (If You Opt Out)

If you choose not to use the Rent-a-Room scheme and instead claim actual expenses, you can deduct:

Direct costs

Cleaning and laundry — costs of preparing the room between guests
Toiletries and supplies — soap, shampoo, towels, bedding replacements
Airbnb service fees — the platform's cut
Key management — lockboxes, smart locks, key cutting
Guest amenities — tea, coffee, welcome packs

Household costs (proportional)

Council tax — the proportion relating to the let room
Utilities — gas, electricity, water (proportional)
Insurance — if you have additional hosting insurance
Internet and broadband — proportional to guest use
Mortgage interest — a proportion, subject to Section 24 restrictions
Repairs and maintenance — to the room or shared areas used by guests

Capital costs

Furniture and furnishings — you can claim a wear-and-tear deduction or the cost of replacing furnishings
Improvements to the room — painting, new flooring, etc. (note: improvements that increase the property's value may be treated as capital expenditure rather than revenue expense)

Calculating proportional costs can be fiddly. A common approach is to divide by the number of rooms in the property and then by the number of nights the room is let versus vacant.

For most Airbnb hosts renting a single spare room, the Rent-a-Room scheme is simpler and usually more beneficial. But if you are hosting year-round and have significant costs, claiming actual expenses could save you more.

Registering and Filing

If you are within the £7,500 Rent-a-Room allowance

You do not need to do anything. The relief is automatic, and you do not need to file a tax return just because of your Airbnb income.

However, if you already file a Self Assessment for other reasons (self-employment, other rental income, etc.), you should still include your Airbnb income on your return and claim the Rent-a-Room relief.

If you exceed £7,500

You need to file a Self Assessment tax return. If you do not already file one, you will need to register with HMRC. The property income goes on supplementary pages SA105.

If you opt out of Rent-a-Room

If you want to claim actual expenses instead of using the Rent-a-Room scheme, you need to formally opt out by writing to HMRC or including a note in your Self Assessment. The deadline for opting out is the first anniversary of the 31 January filing deadline for the relevant tax year.

The Interaction With Other Property Income

This is where things can get a little complex. If you have other property income — for example, from a buy-to-let property or renting out a parking space — you need to think about how the Rent-a-Room scheme interacts with those.

The Rent-a-Room scheme is entirely separate from other property income. Your Airbnb room income up to £7,500 is covered by Rent-a-Room, and your other property income is dealt with under the normal rules (either the £1,000 property allowance or actual expenses).

However, you cannot use both the Rent-a-Room scheme and the £1,000 property allowance. If you have a mix of Rent-a-Room income and other property income, you need to choose which relief to use. In most cases, Rent-a-Room (£7,500) is far more generous than the property allowance (£1,000), so it makes sense to use Rent-a-Room for your Airbnb hosting and declare other property income under normal rules.

Council Tax and Mortgage Considerations

Council tax

If you are renting a room to short-term guests (as with Airbnb), your council tax situation usually does not change — you are still the resident occupier of your main home. However, if you let a room for long-term stays (more than 140 days per year in some areas), your local authority might reclassify part of your property as a business, which could affect your council tax.

In practice, most occasional Airbnb hosts do not run into this issue.

Mortgage

Many residential mortgages include clauses that prohibit or restrict subletting. Strictly speaking, renting a room on Airbnb could breach your mortgage terms if you have not informed your lender.

Most major lenders are relatively relaxed about occasional room letting (as opposed to letting the entire property), but it is worth checking your mortgage terms and informing your lender if necessary. Getting a "consent to let" or noting the arrangement with your lender protects you if questions arise.

Home insurance

Similarly, standard home insurance may not cover paying guests. You should tell your insurer that you are hosting on Airbnb. Some insurers offer specific add-ons for short-term letting, and Airbnb itself provides Host Protection Insurance (now called AirCover for Hosts), which offers up to £750,000 in liability coverage — though this should be seen as a supplement, not a replacement for proper insurance.

Practical Tips for Airbnb Hosts

Track your income throughout the year. Airbnb provides earnings summaries, but it helps to have your own records too. Accounted can automatically track your Airbnb income alongside any other earnings, giving you a clear picture of where you stand against the £7,500 threshold.
Keep receipts for guest-related expenses. Even if you are using the Rent-a-Room scheme now, your circumstances might change. Having expense records means you can opt out and claim actual costs if it becomes more beneficial.
Photograph the room's condition. This is more about protecting yourself as a host than about tax, but having date-stamped photos can help if you need to claim for damage or prove the condition of furnishings.
Understand your local rules. Some areas (particularly London) have restrictions on short-term lets. In London, you can let your entire home for up to 90 nights per year without planning permission, but this does not apply to room lets in your main home while you are present.
Consider the impact on benefits. If you receive means-tested benefits, your Airbnb income (even if tax-free under Rent-a-Room) may count as income for benefits purposes. Check with the DWP if you are unsure.

Summary

The Rent-a-Room scheme is one of the most generous tax reliefs available to UK homeowners, and it makes Airbnb hosting a particularly attractive side hustle. Here is the quick version:

Earn up to £7,500 per year tax-free by renting a furnished room in your main home.
The relief is automatic — no application needed.
If you earn more than £7,500, you can either deduct the £7,500 allowance or claim actual expenses.
The scheme applies to rooms in your main home only — not whole-property lets or second homes.
Check your mortgage and insurance terms before hosting.

With a spare room and a bit of effort, you can build a meaningful income stream that is largely or entirely tax-free. Not bad for a side hustle.
