UK buy-to-let tax refers to the income tax rules that apply to landlords receiving rental income from residential property. Since Section 24 of the Finance Act 2015 was fully phased in from April 2021, landlords who are higher or additional rate taxpayers can no longer deduct their mortgage interest directly from rental income. Instead, all rental income is now taxed in full, and only a basic rate (20%) tax credit equal to the mortgage interest paid is allowed against the tax bill. This makes buy-to-let significantly less profitable for higher-rate taxpayers compared to the previous system. Allowable expenses (other than mortgage interest) such as letting agent fees, insurance, maintenance and repairs, accounting fees, and council tax during voids can still be deducted from rental income. There is also a £1,000 property income allowance available to landlords with small amounts of rental income. Landlords who hold properties through a limited company are not subject to Section 24 and can still deduct mortgage interest as a business expense, making incorporation attractive for some investors. Capital gains tax also applies when selling rental property, with rates of 18% (basic rate) or 24% (higher rate) for residential property as of 2024.
Taxable rental profit = gross rent - allowable expenses (excl. mortgage interest); Tax = profit × marginal rate; Tax credit = mortgage interest × 20%
- 1Add up all gross rental income received in the tax year from all rental properties
- 2Deduct allowable expenses: letting agent fees, insurance, repairs, accountancy, council tax (during voids), ground rent, and any other allowable costs (not mortgage interest)
- 3The resulting figure is the taxable rental profit; add this to your other income to determine your marginal tax rate
- 4Calculate income tax on the rental profit at your marginal rate (20%, 40%, or 45%)
- 5Calculate the basic rate tax credit on the mortgage interest paid: mortgage interest × 20%
- 6Subtract the tax credit from your income tax bill to arrive at the actual tax due
- 7For landlords with income below £12,570 total, the personal allowance may reduce or eliminate the tax liability
Old rules: profit = £6,000; tax = £2,400. New rules: profit = £16,000; tax = £6,400; credit = £2,000; net tax = £4,400. Actually pre-credit tax on £16,000 at 40% = £6,400 less £2,000 credit = £4,400.
Under Section 24, the £10,000 mortgage interest is not deducted before calculating tax. The landlord pays 40% tax on the full £16,000 profit (£6,400), then receives a 20% credit on the interest (£2,000), giving a net tax bill of £4,400 versus £2,400 under the old rules.
Tax on profit (£10,500) at 20% = £2,100; credit on £6,000 × 20% = £1,200; net tax = £900
For a basic rate taxpayer, Section 24 does not change the effective tax burden because the credit equals what would have been saved by deducting the interest directly.
If total property income is £1,000 or less, no tax is due and no return needed
The £1,000 property income allowance means landlords with small rental income (e.g. renting a parking space or garage) pay no tax and have no reporting obligation.
Section 24 does not apply to limited companies; full mortgage interest deductible
Limited companies can still deduct mortgage interest fully, making incorporation attractive for higher-rate landlords, though personal extraction of profits (salary or dividends) adds further tax.

If your rental income is pushing you into the higher rate tax band or triggering Section 24 issues, consider whether additional pension contributions could reduce your adjusted net income and bring you back into the basic rate band, restoring full relief on mortgage interest effectively.
