Navigating UK tax when renting out a room in your home can be challenging, especially with changing tax rates, National Insurance rules, and filing deadlines. The UK rent a room relief rules aim to simplify the reporting requirements and provide generous reliefs for individuals letting rooms within their main property. In this complete guide, we explain everything you need to know about UK Rent a Room Relief – including who qualifies, how the £7,500 allowance works, how to calculate any taxable income and the reporting requirements.
Rent a Room Relief At A Glance
UK Rent a Room Relief allows UK homeowners to earn up to £7,500 per year tax-free by renting out furnished accommodation in their main residence. If income exceeds this threshold, only the excess is taxable.
Who Should Read This?
This article is relevant for UK tax resident individuals who receive income from renting a portion of the residence they live in and are therefore likely eligible for Rent a Room relief. For example, renting out a room or annex of your house.
Details on letting a UK property while non-resident and letting a separate rental property can be found in our other articles.

What Income Is Eligible For UK Rent A Room Relief?
Understanding what types of income qualify for relief is key to managing your UK tax affairs and reporting requirements.
For Rent a Room purposes, rental income includes income received from letting furnished accommodation within your main residence. This includes the rents paid by tenants and also any payments the tenants make to you for things such as the use of furniture, utilities, cleaning and ground rent etc. If the tenants contract and pay directly for their own utilities, this is not rental income and does not need to be considered further.
The tenants may have also paid an initial deposit when starting the tenancy. This is not rental income and is not subject to tax.
How Much Is UK Rent A Room Relief?
UK rent a room relief is a tax free deduction of £7,500 per year per property.
Therefore, when renting out a room in your residence, you have two options to calculate the UK taxable profit:
- Deduct the actual costs of the rental business expenses incurred; or
- Deduct the Rent A Room allowance of £7,500.
You can choose whichever option is more beneficial for each tax year. However, you cannot claim both UK Rent a Room Relief and your actual expenses for the same property income.
In many cases, claiming UK Rent a Room Relief is more beneficial than claiming actual expenses, although this depends on your individual circumstances.
The £7,500 UK rent a room relief deduction applies once per property per year. If the property is jointly owned, the £7,500 allowance is split between owners (usually £3,750 each), unless HMRC agrees a different split based on beneficial ownership. If you have multiple tenants then all rents collected should be combined before deducting the £7,500 relief.
Separate rules apply if you let a property you do not live in or have converted the property into separate flats so please read our separate article if this applies to you.
Mortgage Interest Tax Relief (When Using Rent a Room Relief)
Interest on finance costs related to the property (such as mortgage interest) is eligible for UK tax relief. However, it cannot be claimed if you also claim Rent a Room Relief.
For more details regarding claiming actual expenses and mortgage relief, please read our article regarding UK tax on rental income.
How is the UK Tax Calculated?
Should you have any residual UK taxable profit after the UK rent a room relief deduction of £7,500 is claimed, the UK tax due is based on your total taxable income and applicable tax bands. The UK tax on rental income is calculated using the ‘non-savings’ rates which are the same rates as those applied to employment income. The 2026/27 rates are:
| Band | Taxable income | Tax rate |
| Personal Allowance | Up to £12,570 | 0% |
| Basic rate | £12,571 to £50,270 | 20% |
| Higher rate | £50,271 to £125,140 | 40% |
| Additional rate | over £125,140 | 45% |
The above thresholds apply to your total taxable income and therefore, if you also have other sources of UK taxable income (self-employment income, bank interest, dividends etc.) or are also employed, your rental income is taxed at the highest rate that the income falls into.
For example, if you earn a salary of £30,000 and receive rental income from a room in your property of £10,000. You can claim Rent a Room relief of £7,500 resulting in £2,500 of taxable rental profit. This £2,500 sits wholly in the basic rate band and the tax due on that income is £500 (£2,500 x 20%).
*If your UK taxable income exceeds £100,000, you will start to lose entitlement to the personal allowance. The rates shown are for English and Welsh taxpayers. Individuals living in Scotland are subject to different rates of tax.
Can I Choose Not To Claim Rent a Room Relief?
Claiming UK Rent a Room Relief is not mandatory and you can elect not to apply the Rent a Room rules and instead choose to deduct actual expenses incurred.
This will commonly be the case if your actual expenses were more than the Rent a Room deduction of £7,500 or if your total UK taxable income is below the Personal Allowance and you want to carry forward unused mortgage interest tax relief into future years.
What Happens if my Rental Income Exceeds £7,500?
Rental income in excess of the £7,500 Rent a Room deduction is taxable and subject to UK tax at your marginal tax rate. Your total rental income and the Rent a Room deduction should be declared on your UK tax return and the corresponding tax paid to HMRC by 31 January following the end of the tax year.
Can I Still Claim Rent a Room Relief if I Move Out?
No. Rent a Room relief can only be claimed if you are letting furnished accommodation within your main residence. If you move out and the property is no longer your main home, you will no longer qualify for Rent a Room Relief. Instead, the rental income will usually be taxed under the normal UK property income rules, where you can generally claim allowable expenses or, where beneficial, the Property Allowance.
Do I Pay National Insurance on Rental Income in 2026?
No. Rental income is not currently subject to National Insurance even if it exceeds the UK rent a room relief deduction.
Student Loan Repayments on Rental Income
Student Loan repayments are calculated based on your UK taxable income and plan type. UK taxable income in excess of the repayment threshold for your plan is subject to Student Loan repayments at the rate specified in your plan (9% for an Undergraduate Degree or 6% for Postgraduate Student Loans).
Rental income is classed as ‘unearned income’ and is only considered for Student Loan repayments if your total ‘unearned income’ for the year exceeds £2,000.
Therefore, if your taxable rental profit exceeds £2,000 and your total taxable income exceeds the repayment threshold, your rental profit will be subject to Student Loan repayments via your self-assessment tax return.
VAT Rules for UK Tax on Rental Income
Rental income is not subject to VAT and you therefore do not need to register for VAT.
Record Keeping When Claiming UK Rent A Room Relief
You must keep records of your rental income and expenses for UK tax purposes. You do not need to submit the records to HMRC however they must be retained to calculate the UK tax on your rental income. In the event of an HMRC enquiry, HMRC will request copies of these records to validate your rental income and justify the deductions that have been claimed.
You must keep your records for 5 years after 31 January following the end of the tax year. I.e. for the 2026/27 UK tax year, records must be kept until 31 January 2033.
Deadlines and Filing Rules To Claim
If your gross receipts are no more than the Rent a Room threshold, the relief generally applies automatically and you do not normally need to report the income to HMRC.
If your rental income is more than the Rent A Room relief, you are required to declare this to HMRC via a self-assessment tax return. You must first register for self-assessment via Check how to register for Self Assessment – GOV.UK.
The deadline to register for self-assessment is 5 October following the end of the tax year. For example, for 2026/27 UK tax returns, you must register by 5 October 2027.
Once registered, HMRC will issue you with a Unique Taxpayer Reference (UTR) which is a 10-digit identification number necessary to file your tax return.
The deadline to file your tax return and pay any outstanding liabilities is 31 January following the end of the tax year. For example, the 2026/27 UK tax return filing and payment deadline is 31 January 2028.
HMRC may apply interest and penalties if your tax return and payments are not made by this date.
