If you have a spare room sitting empty, renting it out could quietly earn you thousands each year, completely free of tax. The Rent a Room Scheme is a government arrangement that lets owner-occupiers and tenants receive tax-free rental income from furnished accommodation in their only or main home. It is worth being clear from the outset: this is not a blanket exemption for letting an entire property or a second home. The scheme applies specifically to furnished rooms in the home you actually live in, and it is available whether you own the property or rent it.
The annual tax-free limit under the Rent a Room scheme is £7,500. Where someone else in the same property also receives letting income, such as a joint owner, the limit is halved to £3,750 each. This applies regardless of whether the room is let for a full year or just a few months. And here is something many people do not realise: exceeding the threshold does not mean losing the benefit altogether. If your receipts exceed the limit, you may still be able to use the scheme in a way that works in your favour, which is worth understanding before you assume tax is owed.
Who Can Use the Rent a Room Scheme
The rent a room scheme is open to both owner-occupiers and tenants. You do not need to own your home to use it. Broadly, it applies in the following situations:
- You let a furnished room to a lodger in your main home.
- Your letting activity amounts to a trade, such as running a guest house or bed and breakfast.
- You provide additional services to your lodger, such as meals or cleaning.
When the Rent a Room relief does not apply
There are situations where the Rent a Room relief is not available:
- The accommodation is not part of your main home at the time it is let.
- The accommodation is unfurnished.
- The space is used as an office or for another business purpose by the lodger. Note that a lodger who occasionally works from your home in the evenings or at weekends, or a student using a study area, does not trigger this exclusion.
- The property has been converted into separate, self-contained flats. Where a home has been permanently divided this way, the Rent a Room scheme generally does not apply. However, a temporarily divided space or a self-contained annexe that forms part of the main dwelling may be treated differently depending on the specific circumstances. If your property includes a self-contained annexe, it is worth taking case-specific advice before assuming the scheme applies or does not apply.
The shared occupancy requirement
One point that catches many people out is the shared occupancy condition. For the Rent a Room relief to apply, you or a member of your household must actually be living in the property for all or part of the period during which the letting takes place. This is not just a technical detail. It means that if you let your entire home while you are away, whether for a holiday, work, or any other reason, the letting will usually fall outside the Rent a Room scheme entirely. The relief is designed for lodger arrangements, not whole-home lets, while the owner is absent.
Living abroad and letting your UK home
This is an area where many UK landlords make incorrect assumptions. If you live abroad and let out your UK home, you cannot use the Rent a Room Scheme, even if the property was previously your main home and even if you intend to return. The scheme requires the property to be your only or main home at the time of the letting. Once you are resident abroad, that condition is no longer met, and any rental income becomes subject to tax in the usual way. If you are planning to move abroad temporarily while letting your home, it is important to understand this before assuming the scheme will continue to apply.
Beyond the Rent a Room Scheme limitations, non-resident landlords must follow specific filing rules. Learn more about your requirements in our guide to Airbnb Accounting for Non-UK Residents.
What Counts as Income
When working out whether your income falls within the limit, you need to look at your gross receipts rather than your profit. Your gross receipts include your rental income before any expenses are deducted, any amounts you receive for meals, goods and services such as cleaning or laundry, and any balancing charges. You count your gross receipts across the full tax year.
How the Rent a Room Tax-Free Allowance Works
The Rent a Room tax-free limit is £7,500 a year, or £3,750 if the income is shared with someone else in the same property. If your gross receipts do not exceed your limit, you are automatically exempt from tax on that income. You do not need to notify HMRC about this income where your qualifying receipts fall within the limit. The exemption applies automatically, and no election or claim is required.
If your receipts exceed the limit, you have two options for calculating your tax.
Method A: Tax on actual profit (the default)
Method A is the default position. HMRC will apply it automatically unless you elect otherwise. Under this method, you pay tax on your actual profit, which is your total receipts minus any allowable expenses and capital allowances. This method tends to work in your favour if you have significant costs associated with the letting, such as wear and tear, utility contributions, or other deductible expenses.
Method B: Tax on receipts above the threshold
Method B only applies if you actively elect for it. Under this method, you take your gross receipts, subtract the applicable limit of £7,500 or £3,750, and pay tax on the difference. The important trade-off is that you cannot deduct any expenses or capital allowances whatsoever under Method B. It is generally more straightforward, but it works best when your actual costs are low.
You can switch between Method A and Method B from one year to the next, but you must inform HMRC of your choice within the required time limit. Once you elect for Method B, you remain on it until you notify HMRC that you wish to switch back. Method B also ceases automatically in any year where your rental income falls back within the Room to Rent tax-free limit.
A worked example
Say you rent a furnished room and receive £9,000 in gross receipts over the year. Your allowable expenses, including a contribution to heating and some wear and tear, come to £2,800.
Under Method A, your taxable profit would be £9,000 minus £2,800, leaving £6,200 subject to tax.
Under Method B, your taxable amount would be £9,000 minus £7,500, leaving £1,500 subject to tax. No expenses can be deducted.
In this case, Method B produces a lower tax bill, making it the better choice for that year. However, if your expenses were higher, say £5,000, Method A would bring the taxable figure down to £4,000, making it the more beneficial option. This is why it is worth doing the calculation both ways before deciding which method to use.
Choosing the Right Method
Whether Method A or Method B works out better depends entirely on your own circumstances. If your expenses are high relative to your income, Method A is likely to give you a lower tax bill because you can deduct those costs. If your expenses are low, the simplicity of Method B may be more appealing, though the tax bill could be higher. It is worth calculating both before making a decision.
Telling HMRC The Rent a Room Scheme
You must tell HMRC within one year of 31 January following the end of the relevant tax year if you do not want to use the scheme when your receipts are below the limit, for example, because you want to claim a loss, or if you want to start or stop using Method B.
To make this concrete: if you are deciding about the tax year ending 5 April 2024, the 31 January following that year falls on 31 January 2025. You then have one year from that date, meaning your deadline to notify HMRC would be 31 January 2026. Missing this deadline means HMRC will apply the default position for that year, and you will not be able to elect otherwise after the fact.
The time limit can only be extended in exceptional circumstances, such as a serious illness that made it impossible for you to deal with your tax affairs during that period.
Losses
One important point is that you cannot create a loss while using the Room to Let scheme under the exempt route or under Method B. If you want to create a loss and carry it forward against future rental profits, you need to opt out of the scheme and tell HMRC you want to pay tax on your income less expenses using Method A.
If You Move Home During the Year
If you let a room in both your old and new homes during the same year, you add together the total gross receipts from both properties. If the combined total stays below the limit, you do not pay tax on those lettings. It is worth noting that this aggregation principle is not limited to a straightforward old-home-and-new-home situation. Wherever there is more than one qualifying Rent a Room source in the same tax year, HMRC looks at the combined total of all relevant receipts when testing whether you have exceeded the threshold. The limit applies to the individual, not to each property separately.
What You Need to Consider Before Appling for Rent a Room Scheme
Before relying on the Rent a Room scheme, it is worth working through a few practical points. First, confirm that the room you are letting is furnished, as the scheme does not apply to unfurnished accommodation. Second, satisfy yourself that the property is your only or main home at the time of the letting, not a second property or somewhere you have moved away from. Third, compare your gross receipts to the applicable threshold, and remember to aggregate all qualifying sources if you have more than one. Fourth, keep clear records of the rent you receive and any service charges you pass on, as these will be relevant if your receipts exceed the limit and you need to choose between the two calculation methods. Finally, if you intend to opt out of the Room to Let scheme or elect for Method B, check the deadline that applies to your situation and make sure you notify HMRC in time.
Conclusion
The Rent a Room Scheme is a practical option for anyone with a spare furnished room in their main home. The automatic exemption below the limit means that for many people, there is very little administration involved. Where income exceeds the limit, the choice between the two calculation methods provides some flexibility to keep the tax bill as low as possible. If you are unsure which approach is right for your situation, speaking to a qualified tax adviser is a sensible first step.
