| Rule | 2026/27 | From 2027/28 |
|---|---|---|
| Property income tax rates | 20% / 40% / 45% | 22% / 42% / 47% |
| Mortgage interest relief | 20% tax credit | 22% tax credit |
| Property allowance | £1,000 | £1,000 |
| Rent a Room relief | £7,500 | £7,500 |
In short: rent minus allowable expenses gives your rental profit. That profit is added to your other income and taxed at your marginal rate. Mortgage interest is not deducted; instead you receive a tax credit of 20% of the interest, limited to your rental profit.
A landlord earns £35,000 from employment, receives £15,000 rent, pays £3,000 of expenses and £6,000 of mortgage interest. Rental profit is £12,000. The extra Income Tax is about £3,045, less a £1,200 finance cost credit, so roughly £1,845 is due.
Property income will be taxed at separate rates of 22%, 42% and 47%, with mortgage interest relief at 22%. Higher-rate landlords should plan now. Our landlord tax returns service files your return, and the Let Property Campaign helps if rent was missed. More on our tax calculators page.
