Tax on Rental Income: A Complete Guide to What You'll Pay in 2026/27

Tax on rental income in the UK is charged at your normal income tax rate, 20%, 40%, or 45%, on the profit left after deducting allowable expenses, with the rate depending on where your total income falls across the tax bands. Rental income is added to your other taxable income, such as a salary or pension, so a property can push part of your income into a higher band even when the rent alone looks modest. Understanding how much tax you pay on rental income in 2026/27 means understanding allowable expenses, the mortgage interest restriction, and how rental profit stacks on top of your other earnings. Blue Tick Accountants, a Guildford-based UK tax advisory and accountancy practice, helps landlords across the UK calculate and reduce their property tax bills. This guide explains the landlord income tax rates for 2026, what you can deduct, how National Insurance interacts with rental income, and what your bill looks like at different income levels.

Key Takeaways

• Rental profit is taxed at your marginal income tax rate of 20%, 40%, or 45% in 2026/27, after allowable expenses are deducted from rental income.
• The personal allowance of £12,570 means the first £12,570 of total income is tax-free, but it is withdrawn by £1 for every £2 of income above £100,000.
• Mortgage interest is no longer deductible from rental profit and instead gives a 20% tax credit under the Section 24 finance costs restriction.
• Rental income is not subject to National Insurance for ordinary property investors, so no Class 2 or Class 4 NI is due on rental profit.
• The £1,000 property allowance lets landlords with gross rental income of £1,000 or less pay no tax and make no report on that income.
• From 6 April 2026, landlords with qualifying income above £50,000 must follow Making Tax Digital for Income Tax, keeping digital records and filing quarterly updates.

How Is Rental Income Taxed in the UK in 2026/27?

Rental income is taxed as part of your total taxable income at the same rates as employment or pension income, so the tax you pay depends on your overall earnings rather than the rent in isolation. You calculate your rental profit by taking total rents received and deducting allowable expenses. That profit is then added to your other income, and income tax is charged across the bands for 2026/27: the personal allowance covers the first £12,570, the basic rate of 20% applies from £12,571 to £50,270, the higher rate of 40% applies from £50,271 to £125,140, and the additional rate of 45% applies above £125,140.

Because rental profit sits on top of your other income, the rate it suffers is your marginal rate. A landlord whose salary already uses the basic-rate band will pay 40% on rental profit that spills into the higher-rate band. This stacking effect is the single most important thing to grasp when working out how much tax rental income costs you.

What Expenses Can Landlords Deduct From Rental Income?

Landlords can deduct expenses incurred wholly and exclusively for renting out a property, which reduces the taxable rental profit. Allowable expenses include letting agent and management fees, property repairs and maintenance (but not improvements), landlord insurance, ground rent and service charges, council tax or utility bills you pay, accountancy fees, and the cost of replacing domestic items such as furniture and white goods under the replacement of domestic items relief.

Capital costs, such as extending a property or installing something that was not there before, are not deductible against rental income and are instead set against any future capital gain. The distinction between a repair (deductible) and an improvement (capital) is a frequent source of HMRC enquiries, so keeping clear records and invoices matters.

Landlords with gross rental income of £1,000 or less in a tax year can use the £1,000 property allowance instead of deducting actual expenses, which means no tax and no need to report that income. Where rents exceed £1,000 but expenses are low, you can choose to deduct the £1,000 allowance rather than your actual costs if that gives a better result.

How Does the Mortgage Interest Restriction Affect Your Tax?

Mortgage interest is no longer an allowable expense against rental profit and instead gives a basic-rate tax credit of 20%, under the Section 24 finance costs restriction. This means you calculate your rental profit without deducting any mortgage interest, pay tax on that higher profit, and then reduce your tax bill by 20% of the interest paid.

For basic-rate taxpayers the effect is broadly neutral, because relief at 20% matches the rate at which the profit is taxed. For higher-rate and additional-rate taxpayers the restriction increases the real tax cost, because the profit is taxed at 40% or 45% while the interest relief is capped at 20%. The restriction can also inflate your stated profit enough to push you into a higher tax band or to trigger the withdrawal of your personal allowance above £100,000.

Worked example. A higher-rate landlord receives £20,000 in rent, pays £6,000 of mortgage interest, and has £3,000 of other allowable expenses. Taxable rental profit is £20,000 less £3,000, which is £17,000 (interest is excluded). Tax at 40% is £6,800, reduced by a 20% credit on the £6,000 interest, which is £1,200, giving a final tax bill of £5,600 on the property.

Do You Pay National Insurance on Rental Income?

Most landlords pay no National Insurance on rental income, because letting property is treated as investment income rather than self-employment. Ordinary buy-to-let and residential letting therefore attracts income tax but no Class 2 or Class 4 National Insurance contributions, which is a key difference from sole trader trading profit.

The exception is where letting amounts to a genuine business run on a commercial basis with significant personal involvement, such as running serviced accommodation or a portfolio with substantial day-to-day work. In those cases HMRC may treat the activity as a trade and Class 2 or Class 4 NI could apply. For the vast majority of landlords holding property as an investment, rental profit is taxed at income tax rates only, with no NI added on top.

How Much Tax Will You Pay at Different Income Levels?

The tax you pay on rental income depends on your total income, so the same rental profit produces very different bills for a basic-rate and a higher-rate taxpayer. The three worked examples below assume no mortgage interest, to isolate the band effect, and use the 2026/27 rates and the £12,570 personal allowance.

A landlord with no other income and £15,000 of rental profit uses the personal allowance against the first £12,570, leaving £2,430 taxed at 20%, a bill of £486.

An employed landlord earning a £40,000 salary with £8,000 of rental profit has already used the personal allowance and most of the basic-rate band against the salary. The salary uses the band up to £40,000, so £10,270 of basic-rate band remains. All £8,000 of rental profit falls within it and is taxed at 20%, a bill of £1,600.

An employed landlord earning a £60,000 salary with £8,000 of rental profit is already a higher-rate taxpayer, so the whole £8,000 of rental profit is taxed at 40%, a bill of £3,200. The same profit costs this landlord twice as much as the £40,000 earner, purely because of where it stacks.

How Does Making Tax Digital Affect Landlords?

Making Tax Digital for Income Tax (MTD for IT) is now live and changes how many landlords keep records and report rental income. From 6 April 2026, landlords with qualifying income above £50,000 must keep digital records and submit quarterly updates to HMRC through compatible software, followed by a final declaration by 31 January. Qualifying income is gross rental income (plus any self-employment income) before expenses, so the threshold can be reached more easily than landlords expect.

Those with qualifying income above £30,000 join from April 2027, and those above £20,000 from April 2028. Landlords below £20,000 continue to file a single annual self-assessment return for now. Any landlord approaching the £50,000 line should be putting digital record-keeping in place for the current 2026/27 year so the quarterly process is ready when it bites.

Frequently Asked Questions

How much tax do I pay on rental income in the UK?

You pay tax on rental income at your marginal income tax rate, which is 20%, 40%, or 45% in 2026/27, on the rental profit after allowable expenses. Rental profit is added to your other income, so the rate depends on your total earnings. A higher-rate taxpayer pays 40% on rental profit, while a basic-rate taxpayer pays 20%.

Is rental income taxed differently from a salary?

Rental income is taxed at the same income tax rates as a salary, but two key differences apply. Rental income carries no National Insurance for ordinary investors, whereas salary does. Mortgage interest on a rental property gives only a 20% tax credit under the Section 24 restriction, rather than being fully deductible as most business costs are.

What is the £1,000 property allowance?

The £1,000 property allowance lets landlords earn up to £1,000 of gross rental income in a tax year with no tax to pay and nothing to report to HMRC. If your rental income exceeds £1,000, you can either deduct your actual allowable expenses or claim the £1,000 allowance instead, whichever leaves you with the lower taxable profit.

Do I pay National Insurance on rental income?

No, most landlords do not pay National Insurance on rental income, because letting property is treated as investment income rather than self-employment. Class 2 and Class 4 NI do not apply to ordinary buy-to-let profit. The exception is where letting is run as a genuine trade with significant personal involvement, such as serviced accommodation, when NI may apply.

When do landlords have to use Making Tax Digital?

Landlords with qualifying income above £50,000 must use Making Tax Digital for Income Tax from 6 April 2026, keeping digital records and filing quarterly updates plus a final declaration by 31 January. Those above £30,000 join from April 2027, and those above £20,000 from April 2028. Qualifying income is measured on gross rental income before expenses.
