Tax on Rental Income: UK Landlord Guide for 2026/27
Renting out a property in the UK means paying tax on the profit, not the rent. This guide explains the £1,000 property allowance, the expenses you can deduct, the 20, 40 and 45 percent rates, and how to report it to HMRC.

Key takeaways
- You pay tax on rental profit, rent minus allowable expenses, not the full rent.
- The first £1,000 of gross property income each year is tax-free.
- Rental profit is added to your other income and taxed at 20%, 40% or 45% in 2026/27.
- Mortgage interest is no longer an expense: a 20% tax credit instead.
- Report rental income on a Self Assessment return, due online by 31 January.
What counts as rental income
Rental income is money received for letting out property: a house, a flat, a room in a property you do not live in, or commercial premises. It includes the rent and payments for services you provide, such as cleaning. A tenant deposit is not income: you hold it and return it.
Tax is charged on the profit: rent minus the expenses HMRC allows.
The £1,000 property allowance
The property allowance exempts up to £1,000 a year of property income from tax. If your gross property income is £1,000 or less in a tax year, you need not tell HMRC or pay tax on it. Keep a record anyway.
Above £1,000, deduct your actual expenses or the £1,000 allowance, not both. For a small let the allowance often wins; real expenses usually beat £1,000 for a mortgaged buy-to-let.
Between £1,000 and £2,500, contact HMRC; above £2,500, register for Self Assessment. Joint owners each get up to £1,000. The allowance cannot be used on Rent a Room income or with the mortgage interest tax reducer.
Allowable expenses you can deduct
An expense is allowable if it is wholly and exclusively for the rental business: letting agent fees, landlord insurance, maintenance and repairs, ground rent and service charges, council tax and utilities you pay rather than the tenant, legal fees, like-for-like replacement of domestic items, and accountancy fees.
Capital improvements are not deductible: an extension or new kitchen improves the property rather than repairing it. Those costs may reduce capital gains tax when you sell.
How much tax you will pay: the rates
Your rental profit is added to your other income and taxed at your marginal rate. In England, Wales and Northern Ireland in 2026/27: up to £12,570 at 0%, £12,571 to £50,270 at 20%, £50,271 to £125,140 at 40%, over £125,140 at 45%.
Your salary decides the rate: the profit sits on top of it. If your salary already uses your allowance and basic rate band, rental profit is taxed at 40% from the first pound. Above £100,000, the personal allowance falls by £1 for every £2, vanishing at £125,140. Scotland sets its own rates; ordinary rental income carries no National Insurance.
Worked example: a landlord at the basic rate
Worked example, labelled illustrative. A landlord earns £38,000 and lets a flat for £1,000 a month (£12,000 a year). Her expenses are £1,200 in agent fees, £300 of insurance and £900 of repairs (£2,400 total), plus £3,600 of mortgage interest.
Her profit is £9,600. With her salary, total income is £47,600, below the £50,270 threshold, so the profit is taxed at 20%: £1,920. Less the finance cost credit of £720 (20% of £3,600), the tax due on the rent is £1,200.
With the allowance instead, profit would be £11,000, taxed at £1,480 after the £720 credit. Real expenses save £280. Before you buy, check the numbers with our rental yield calculator.

Rent a Room: the £7,500 exception
Under the Rent a Room Scheme you can earn up to £7,500 a year tax-free from a furnished room in your own home, automatically. Shared income halves it to £3,750 each. Above the threshold, opt in and pay tax on the excess, or declare the full income and deduct expenses.
How to report rental income
Rental income is reported through Self Assessment, on the UK property pages (SA105). Register by 5 October following the tax year if you have never filed before. The online return and any tax owed are due by 31 January after the tax year ends: 31 January 2027 for 2025/26. Our Self Assessment tax return guide explains who must file, and our tax year dates guide lists the deadlines.
Payments on account may apply: half on 31 January, half on 31 July. From April 2026, landlords with qualifying income over £50,000 must keep digital records and send quarterly updates under Making Tax Digital.
What changes from April 2027
From 6 April 2027, property income gets its own rates under section 7 of Finance Act 2026: 22% basic, 42% higher and 47% additional, with the finance cost credit rising to 22%. These apply in England, Wales and Northern Ireland.
Budget 2026 announced a further rise to 24%, 44% and 49% from the same date, but that is not yet law: it needs Finance Bill 2026-27 to pass.
Keeping records HMRC will accept
Keep every record behind the figures on your return: tenancy agreements, rent received, invoices and receipts, and bank statements. HMRC can penalise records that are not accurate, complete and readable.
Keep business records for at least five years after the 31 January filing deadline, so records for 2025/26 must be kept until at least 31 January 2032.
Mistakes landlords make
The costliest mistake is not declaring the income: HMRC receives data from letting agents and banks, and undeclared rent can mean back tax, interest and penalties. Next, deducting mortgage interest as an expense, not allowed since April 2020, or claiming the £1,000 allowance and expenses together. A late return brings an automatic £100 penalty, even with no tax owed.
