Whether you own one buy-to-let property or a growing portfolio, understanding how rental income is taxed is one of the most important responsibilities you have as a UK landlord. Tax on rental income is not simply a flat charge on the rent you receive — it depends on your total income, your ownership structure, the type of property you let, and several reliefs and allowances that can significantly reduce what you owe. This guide covers everything you need to know for the current tax year, including the major changes taking effect from April 2027.
What Counts as Rental Income?
Rental income is not limited to the monthly rent your tenant pays. HMRC treats the following as taxable rental income:
- Rent payments
- Charges for services such as cleaning or gardening
- Utility bills paid by the tenant on your behalf
- Any amount retained from a tenant’s deposit at the end of a tenancy
- Non-refundable fees, booking fees, and pet deposits charged upfront
- Furniture usage charges and any other sums received from occupying the property
Refundable tenancy deposits do not count as income when received, as they belong to the tenant. However, any portion you retain at the end of the tenancy becomes taxable income in the year you decide to keep it.
The £1,000 Property Allowance
Every individual landlord is entitled to a £1,000 property allowance per tax year. If your total rental income is £1,000 or less, no tax is due and you are not required to report it to HMRC.
Where your income exceeds £1,000, you must choose one of two options:
- Claim the £1,000 property allowance as a flat deduction
- Deduct your actual allowable expenses instead
You cannot claim both in the same tax year. The property allowance is the better option when your actual expenses are less than £1,000. If your expenses are higher, deducting them reduces your taxable profit further.
Allowable Expenses
Tax is charged only on your net rental profit, your total rental income minus allowable expenses. HMRC permits deductions for costs that are incurred wholly and exclusively for the purpose of letting the property.
Common allowable expenses include:
- Letting agent and management fees
- Buildings and contents insurance premiums
- Maintenance and repairs (not improvements)
- Legal fees for tenancy agreements of one year or less
- Accountancy fees
- Council Tax and utility bills paid by the landlord
- Advertising and administrative costs
Capital expenditure such as purchasing the property itself or carrying out improvements that increase its value, is not an allowable expense for Income Tax purposes.
For furnished residential properties, you can also claim Replacement of Domestic Items Relief, which covers the cost of replacing furnishings, white goods, and soft furnishings on a like-for-like basis.
Section 24: Mortgage Interest Relief
Since April 2020, individual landlords can no longer deduct mortgage interest payments directly from rental income. Instead, a 20% tax credit is applied against the final tax bill, equal to 20% of the annual mortgage interest paid.
This means that higher and additional rate taxpayers no longer receive full relief on mortgage interest costs. A landlord paying 40% tax who pays £10,000 in annual mortgage interest receives only a £2,000 credit, rather than the £4,000 relief previously available under the old system.
From April 2027, the mortgage interest tax credit will increase from 20% to 22%, in line with the new property income tax rates.
How Much Tax Do You Pay on Rental Income?
Rental income is added on top of your other taxable income, such as employment income or pension, and taxed at whatever band your total income falls into. For the 2025/26 tax year, the rates are:
| Income Band | Taxable Income | Rate 2025/26 | Rate from April 2027 |
| Personal Allowance | Up to £12,570 | 0% | 0% |
| Basic Rate | £12,571 to £50,270 | 20% | 22% |
| Higher Rate | £50,271 to £125,140 | 40% | 42% |
| Additional Rate | Above £125,140 | 45% | 47% |
From 6 April 2027, rental income will be subject to separate property income tax rates that are 2 percentage points higher than standard Income Tax rates across every band. This is one of the most significant changes to landlord taxation in recent years and will affect every individual landlord in England, Wales, and Northern Ireland.
Worked Example (2025/26)
You earn a salary of £40,000 and receive net rental income of £15,000, giving a total of £55,000. The portion up to £50,270 is taxed at 20% and the remaining £4,730 at 40%. After applying the mortgage interest tax credit, this gives your final Income Tax bill.
Jointly Owned Rental Property
The tax treatment of jointly owned property depends on the nature of the co-ownership:
- Married couples and civil partners: HMRC taxes rental income on a 50:50 basis by default, regardless of the actual ownership split. To be taxed in proportion to actual beneficial ownership, both parties must submit a Form 17 declaration to HMRC within 60 days
- Unmarried joint owners: Income is taxed according to each person’s actual share of the property, with no default 50:50 rule applying
- Multiple properties: All UK rental properties are treated as a single property business. If you hold jointly owned properties alongside solely owned properties, the income is pooled together
Limited Company Ownership
Some landlords find it more tax-efficient to hold buy-to-let properties through a limited company. Instead of paying Income Tax at the rates above, the company pays Corporation Tax on its rental profits. The current rates are 19% for profits up to £50,000 and 25% for profits above £250,000, with marginal relief applying on profits between those two thresholds.
A significant advantage of the limited company structure is that mortgage interest can still be deducted in full as a business expense — the Section 24 restriction applies only to individual landlords. However, extracting profits from a company as salary or dividends creates additional personal tax obligations, so the overall benefit depends on individual circumstances and should be assessed with professional advice.
Rent a Room Scheme
If you rent out a furnished room in your main home, you may qualify for the Rent a Room Scheme, which allows you to receive up to £7,500 per tax year completely free of Income Tax. Where the income is shared with another person, the threshold halves to £3,750 each.
Below the threshold, you are automatically exempt and have nothing to declare. Above it, you pay tax only on the amount exceeding £7,500. The scheme applies to both long-term lodgers and short-term lettings such as Airbnb bookings, provided the property is your main home and the room is furnished.
Non-Resident Landlords
If you own UK property but live abroad for six months or more per year, HMRC classifies you as a non-resident landlord. You are still liable to UK Income Tax on rental profits from UK property, regardless of where you are tax resident.
Under the Non-Resident Landlord Scheme (NRLS), your letting agent or tenant is required to deduct basic rate Income Tax (20%) from the rent before paying it to you, then pay that tax directly to HMRC quarterly. Alternatively, you can apply to HMRC using form NRL1i to receive rent gross and manage your own tax obligations through Self Assessment instead.
Non-resident landlords who also pay tax on UK rental income in their country of residence may be able to claim relief under a double taxation agreement to avoid being taxed twice on the same income.
Reporting Rental Income to HMRC
The table below summarises the reporting obligations based on your annual rental income:
| Annual Rental Income | Reporting Requirement |
|---|---|
| Less than £1,000 | No reporting required |
| £1,000 to £2,500 | Contact HMRC directly |
| £2,500 to £9,999 after expenses, or £10,000 before expenses | Register for and complete Self Assessment |
Self Assessment returns for the 2025/26 tax year must be submitted by 31 October 2026 (paper) or 31 January 2027 (online), with any tax owed paid by 31 January 2027.
Making Tax Digital
From 6 April 2026, landlords with gross qualifying property and self-employment income exceeding £50,000 must comply with Making Tax Digital for Income Tax Self Assessment (MTD for ITSA). This requires digital record-keeping and quarterly submissions to HMRC through approved software, rather than a single annual return. The threshold falls to £30,000 from April 2027 and £20,000 from April 2028.
Rental Losses
Where allowable expenses exceed rental income in a tax year, you have made a rental loss. The rules are straightforward:
- Losses from one property in your UK portfolio can be offset against profits from another in the same tax year
- Any remaining loss carries forward indefinitely to offset future rental profits
- Rental losses cannot be offset against employment income, pension income, or any other non-property income

Frequently Asked Questions:
Do I always have to pay tax on rental income?
Not necessarily on every pound. The first £1,000 of rental income each tax year is covered by the property allowance and is tax-free. If your rental income exceeds £1,000, the taxable portion is your profit after deducting either the property allowance or actual allowable expenses, depending on which you choose to claim.
How does rental income affect my tax band?
Rental income is added to all your other sources of income, such as salary or pension, and the combined total determines your tax band. This means rental income could push you into the higher or additional rate band even if your employment income alone would not reach those thresholds.
Can I deduct mortgage interest from my rental income?
Not as a direct deduction. Since April 2020, individual landlords receive a 20% tax credit on mortgage interest payments rather than being able to deduct it from rental income. This credit is applied against your final tax bill. From April 2027, the credit increases to 22%.
What is the difference between a property allowance and allowable expenses?
The property allowance is a flat £1,000 deduction available to every individual landlord. Allowable expenses are the actual costs you have incurred in running your rental property. You must choose one or the other and cannot claim both in the same tax year. If your actual expenses exceed £1,000, it is generally more tax-efficient to deduct them instead.
What are the new property income tax rates from April 2027?
From 6 April 2027, rental income earned by individual landlords will be taxed at slightly higher rates than standard Income Tax. The basic rate rises from 20% to 22%, the higher rate from 40% to 42%, and the additional rate from 45% to 47%. Limited company landlords are unaffected as they continue to pay Corporation Tax.
What is Making Tax Digital and when does it apply to me?
MTD for Income Tax requires landlords to keep digital records and submit quarterly updates to HMRC through approved software instead of filing a single annual return. From April 2026, it applies to landlords with gross qualifying income over £50,000. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028.
What happens if I have not declared rental income in previous years?
HMRC identifies undeclared rental income through Land Registry data, letting agent returns, rental platform disclosures, and buy-to-let mortgage records. If you have undeclared income, you can come forward voluntarily through the Let Property Campaign, which typically results in lower penalties than if HMRC contacts you first.
