Worth knowing

The rules for taking in a lodger.

It must be your main home

Rent a Room only applies to furnished accommodation in the home you live in. It does not cover a separate self-contained flat let unfurnished, or a home you do not live in.

Check your mortgage and insurance

Tell your lender and home insurer that you have a lodger. Most allow it, but some have conditions.

Tax year 6 April 2026 to 5 April 2027. Not tax advice.

THE RENT A ROOM GUIDE

Rent a Room relief, explained

You can earn up to £7,500 a year tax-free by letting furnished rooms in your own home. This guide explains what qualifies, what counts towards the limit, how to choose between the scheme and the normal method when you earn more, and what to check before taking in a lodger.

1The basics

What Rent a Room is

The Rent a Room scheme lets you receive up to £7,500 a year from letting furnished accommodation in your main home without paying tax on it. It applies whether you own your home or rent it, as long as your landlord allows lodgers.

The limit applies to the tax year, from 6 April to 5 April, and is not reduced if you only let a room for part of the year.

2Eligibility

What qualifies

  • Furnished rooms in your only or main home, let to a lodger.
  • Bed and breakfast or guest house income from rooms in your home.
  • Short stays, such as letting a spare room to holiday guests, if you live there at the same time.

It does not cover:

  • a separate, self-contained flat let unfurnished;
  • a home you do not live in;
  • rooms used as an office or for a business.

You must live in the home for at least part of the time the room is let in each tax year.

3Receipts

What counts towards the limit

The £7,500 is a limit on gross receipts, not profit. It includes the rent and anything you charge for extras, such as meals, cleaning, laundry, or a share of energy and broadband bills.

A lodger paying £650 a month plus £50 for bills
  1. Rent£650 × 12£7,800
  2. Bills£50 × 12£600
Receipts for the limit£8,400

That is over the limit, even though the rent alone is only £300 over.

4Under the limit

Under the limit

If your receipts are £7,500 or less, the relief is automatic. You pay no tax on the income and you do not need to tell HMRC or fill in a tax return for it.

When you might opt out

If your costs are higher than your receipts, you make a loss. You can opt out of the scheme for that year to record the loss and carry it forward against future rental profits.

5Over the limit

Over the limit: two methods

If your receipts are over £7,500, you must tell HMRC and choose one of two methods each year:

Rent a Room method
Taxable amount
Receipts above £7,500
Expenses
Cannot be claimed
Best when
Your costs are under £7,500
Normal method
Taxable amount
Receipts minus expenses
Expenses
Actual costs claimed
Best when
Your costs are over £7,500

The profit is added to your other income and taxed at your normal Income Tax rates. There is no National Insurance on it.

6Worked examples

£6,000£0£30,000£0£1,200

£12,000£2,000£30,000£900£2,000
£12,000£9,000£30,000£900£600

In most cases the Rent a Room method wins, because few lodger arrangements cost more than £7,500 a year to run. The last row shows the exception: with £9,000 of costs, the normal method saves £300.

7Sharing

Sharing the limit

If more than one person receives income from letting rooms in the same home, such as a couple who both own it, the limit is halved to £3,750 each. This applies even if one of you receives all the rent.

A couple sharing £6,000 of rent
  1. Each person's share of receipts£3,000
  2. Each person's limit£3,750
Tax for each£0

If one person alone receives £6,000 but the other also receives some rent from the home, the first person's limit is £3,750 and £2,250 is taxable: £450 at the basic rate.

9Before you start

Practical checks before taking a lodger

  • Mortgage: tell your lender. Most allow a lodger, but some need consent.
  • Home insurance: tell your insurer, as a lodger can affect your cover.
  • Tenancy: if you rent, check your tenancy allows a lodger and get your landlord's permission.
  • Right to rent: in England you must check that an adult lodger has the right to rent.
  • Council tax: a lodger who lives with you as their main home ends any single person discount.
  • Benefits: lodger income can affect means-tested benefits; check before you start.
  • Agreement: a simple written lodger agreement setting out rent, notice and house rules avoids disputes.
10The difference

Lodger or tenant?

A lodger lives in your home and shares facilities such as the kitchen or bathroom with you. They have fewer rights than a tenant: they are usually an "excluded occupier", so you can end the arrangement with reasonable notice, often the length of the rent period, without a court order.

If you move out and let the whole home, or let a self-contained part with its own front door and facilities, the person is more likely to be a tenant with full tenancy rights. That is not covered by Rent a Room and is taxed as normal rental income.

11Worked example

Example: a lodger for part of the year

Priya lets her spare room for £700 a month from October to March, six months of the tax year. She earns £32,000 from her job.

Six months at £700
  1. Rent received£700 × 6£4,200
  2. Rent a Room limit£7,500
Tax to pay£0

Her receipts are under the limit, so there is nothing to pay or report. If the lodger stayed all year, she would receive £8,400 and pay tax on £900 under the scheme: £180 at the basic rate.

Questions

Frequently asked

How much can I earn tax-free from a lodger?

Up to £7,500 a year under the Rent a Room scheme, or £3,750 each if someone else also receives rent from the home.

Does the limit include bills?

Yes. It is a limit on everything you receive, including charges for meals, cleaning and bills.

What if I earn more than £7,500?

Register for Self Assessment and either pay tax on the amount above £7,500, or use the normal method and deduct your actual expenses.

Do I need to tell HMRC if I earn under £7,500?

No. The relief is automatic and you do not need to report it.

Does Rent a Room apply to Airbnb?

It can, for furnished rooms in your main home while you live there.

Does it apply to Airbnb guests?

It can, if the guests stay in a furnished room in your main home while you live there. Letting the whole home while you are away does not qualify.

What if my lodger only stays a few months?

You still get the full £7,500 limit for the tax year. It is not divided by the number of months.

Can I claim the scheme and expenses together?

No. Under the scheme you cannot deduct any expenses.

Do I have to protect a lodger's deposit?

Not usually. Deposit protection rules apply to assured shorthold tenancies, not lodgers who live with you.

Is the limit different in Scotland or Wales?

No. Rent a Room is a UK-wide Income Tax relief. Scottish taxpayers pay Scottish rates on any taxable amount.

Does Rent a Room affect Capital Gains Tax when I sell?

Having a lodger who shares your home does not normally reduce Private Residence Relief, so you would not usually pay CGT on your home because of it.

Can a lodger stay if I rent my home?

Only if your tenancy allows it. Ask your landlord for written permission first.
