The Rent-a-Room scheme has been available since 1992 and the £7,500 threshold has been in place since April 2016. It is one of the most generous and simplest tax reliefs available to UK homeowners, but it comes with conditions, and the automatic relief only applies in specific circumstances.
Importantly, a lodger arrangement is legally distinct from a tenancy. A lodger lives in the same property as the owner or tenant and shares facilities. Lodgers do not have security of tenure under the Renters' Rights Act 2025, the new post-commencement tenancy framework does not apply to lodger arrangements where the landlord lives in the same property.
Who qualifies for Rent-a-Room relief?
The relief applies when all of the following conditions are met:
- You own or rent your home and live there yourself, the property must be your only or main residence
- You let a furnished room or rooms in the property to one or more lodgers
- The room is furnished, unfurnished room lets do not qualify for Rent-a-Room relief
- The let is within the same building as your main home, a self-contained flat within your house may qualify, but a completely separate property does not
- Shared ownership and tenants: if you rent the property from a landlord and sublet a room, you can also use Rent-a-Room relief, but check your tenancy agreement permits subletting. Under a periodic Assured Tenancy from 1 May 2026, subletting remains subject to landlord consent
- Joint owners or occupiers: if two people share ownership and let rooms, the £7,500 threshold is split equally, each person's relief threshold is £3,750
How the £7,500 threshold works
The relief is structured around gross annual income from the lodger:
- Below £7,500 gross income: no tax is due, no Self Assessment return is needed solely because of the lodger income, and you do not need to notify HMRC unless you receive a notice to file
- Above £7,500 gross income: you must file a Self Assessment return. You then choose between two options: (1) pay tax only on the amount above £7,500, OR (2) opt out of the scheme and deduct actual allowable expenses from the full gross income
- The £7,500 threshold is per property, not per lodger, if you have two lodgers paying £4,000 each (£8,000 total), the total counts against the threshold
- Gross income includes rent, meals, laundry services, and any amounts charged for utilities, everything the lodger pays you counts towards the £7,500
- Deposits are not income, a deposit held pending return is not rent and does not count towards the threshold
Option 1, Pay tax on income above £7,500
If you stay in the scheme and your income exceeds £7,500, the taxable amount is simply:
- Taxable income = gross lodger income minus £7,500
- Example: £9,000 gross lodger income → £1,500 taxable. At 20% basic rate, tax = £300
- No expense deduction is allowed under this option, you cannot claim mortgage interest, council tax apportionment, or repairs against the excess
- This option is best when your actual allowable expenses are low relative to income, typically simple single-lodger arrangements with no significant maintenance or utility costs attributable to the let
Option 2, Opt out and use actual expenses
If you opt out of Rent-a-Room relief, your lodger income is taxed as standard rental income:
- Gross lodger income minus allowable expenses = taxable profit
- Allowable expenses: a proportional share of council tax, utility bills, insurance, cleaning, repairs, and a proportion of mortgage interest (subject to Section 24 restriction for residential letting)
- Opt-out is best when your expenses exceed £7,500, or when your actual costs are high relative to lodger income, for example a high-value property where proportional expenses are substantial
- Once you opt out, you must file a Self Assessment return with the SA105 property pages
- You can switch between Option 1 and Option 2 in different tax years, there is no permanent election
Lodger vs tenant, the legal distinction
Understanding the legal difference between a lodger and a tenant is critical after the Renters' Rights Act 2025:
- A lodger (occupier sharing with a resident owner or occupier) is a licensee, they have a licence to occupy, not a tenancy. The Renters' Rights Act 2025 does not apply to lodger arrangements where the landlord lives in the property
- A lodger can be asked to leave with reasonable notice (typically 28 days by convention, or the notice period agreed in the lodger agreement), there is no requirement to use Section 8 or the possession grounds regime
- A lodger becomes a tenant if: the owner moves out permanently, or the arrangement is structured to give the lodger exclusive possession of the whole property without shared facilities
- Always use a written Lodger Agreement, not a tenancy agreement, to clearly establish the licence relationship and the absence of exclusive possession
- HMO rules can still apply to a property with lodgers if it becomes occupied by 5 or more people from 2 or more households, check HMO mandatory licensing thresholds even where lodger arrangements are used
Rent-a-Room and Self Assessment
How lodger income interacts with your HMRC reporting obligations:
- Below £7,500 with no other Self Assessment obligation: you do not need to register for Self Assessment. If HMRC sends you a notice to file, declare the lodger income but claim full Rent-a-Room relief
- Already filing Self Assessment: add lodger income to your SA105 property pages. Tick the Rent-a-Room box. If income is below £7,500, the relief fully exempts it
- Above £7,500: you must file SA105 with either the scheme election (taxed on excess) or the opt-out figures (actual expenses). The return is due by 31 January (online) or 31 October (paper) following the end of the tax year
- MTD ITSA: once Making Tax Digital for Income Tax applies to you (from April 2026 if gross income above £50,000), lodger income must be included in quarterly digital updates alongside other rental income
Frequently asked questions
Does the £7,500 threshold apply per lodger or per property?+
Per property. The £7,500 Rent-a-Room threshold applies to total gross lodger income from that property in the tax year, regardless of how many lodgers you have. If you have two lodgers each paying £4,000, the total £8,000 exceeds the threshold and you must file a Self Assessment return. However, if two people jointly own the property and both live there, the threshold is split, each person has a £3,750 threshold.
Does Rent-a-Room relief apply if I rent out an Airbnb room in my home?+
Yes, in principle, short-term lettings in your own home can qualify for Rent-a-Room relief provided the room is furnished and the property is your only or main residence. The same £7,500 threshold applies. However, HMRC may scrutinise arrangements where guests have exclusive use of the entire property while you are away, if you are essentially running a self-contained holiday let from your home address, Furnished Holiday Letting rules (or normal rental income rules) may apply instead.
Do I need to pay National Insurance on lodger income?+
Generally no. Lodger income is property income, not trading income, so National Insurance contributions do not apply. If HMRC were to characterise the arrangement as a trade (for example, if you were running a bed and breakfast with significant services such as cleaning and meals), trading income and Class 2/Class 4 NIC could apply. Pure room rental with the tenant providing their own meals is treated as property income.
Can I take in a lodger if I have a Periodic Assured Tenancy?+
You need your landlord's written consent to sublet or take in a lodger under a Periodic Assured Tenancy (formerly AST). From 1 May 2026, all residential tenancies in England are Periodic Assured Tenancies. Subletting without consent is a breach of tenancy that could give the landlord a Ground 12 Section 8 possession claim. However, the Renters' Rights Act 2025 makes it harder for landlords to refuse lodger consent without good reason, consult the lodger provisions of your tenancy agreement and seek written landlord approval before proceeding.
