How to Use the Rental Income Tax Calculator?
Landlords are now preparing for major shifts in how rental income is taxed in 2026. Our rental income tax calculator is designed to help you estimate your tax and real rental profit in just seconds. Follow these steps to find out the landlord's tax bill:
- Select your tax year first. Select 2025/26 for your current bill and 2027/28 to see how new rates will affect your rental profit.
- Select the type of tenancy, buy-to-let or live-in landlord. (Tax rules are different for both.)
- Enter your annual rental income received and don't deduct anything at this stage.
- Enter the rent you received per month.
- Add your employment income for the year. A higher salary can push your rental income into the 40% tax band, which is why this figure matters.
- If you have any extra sources of income, enter them—for example, a pension, a freelance, or an investment you made (if applicable).
- Click Calculation details to see exactly how the tax bill is worked out.
| Important Note From April 2027, rental income will be taxed at higher rates than other income: 22% (basic rate), 42% (higher rate), and 47% (additional rate), rather than the 2025/26 standard 20%, 40%, and 45%. Make sure your calculator uses the correct rates for your tax year. |
What Is Rental Income Tax in the UK?
Rental income tax is the tax landlords pay on the profit they earn from letting out their property. Only rental profit is taxed, not the full rent you receive. All the allowable expenses are deducted before any tax is calculated.
All the earned rent counts as income, which also includes tenant payments for utilities and services if landlords handle them.
How your Rental Income Tax is Calculated?
Your rental income tax depends on how much a landlord earns from rent, whether they live in the property or not, or how much they earn from other sources, such as a pension, employment, or salary. Here is how tax is calculated on rental income:
- The gross rental income is the full rent you received from tenants before deductions. If landlords have multiple properties, combine all the rents into one figure.
- Minus your allowable expenses, which HMRC allows you to deduct legitimate costs for renting out the property. It may include letting agents' fees, repairs or maintenance, insurance, or accountancy fees. All are subtracted from gross rental income.
- Minus the Property Allowance (£1000) if you haven’t claimed the actual expenses. Most landlords benefit more from actual expenses, but a property allowance is beneficial if your costs are minimal.
Note: The first £1000 of rental income is tax-free
- This is the figure of rental profit on which tax applies– not the full rent you receive.
- Rental profit is added to other income to determine which tax band you fall into. It is stacked on top of your salary, pension, or any other income.
- Tax is applied at your marginal rate given as:
| Tax Year / Period | Basic Rate | Higher Rate | Additional Rate |
| 2025/26 | 20% | 40% | 45% |
| From April 2027 | 22% | 42% | 47% |
See how these rates apply to your income using the rental income tax calculator above.
Mortgage Interest Rule (Section 24):
As of 2026, according to Section 24, you cannot deduct the interest directly from your income. Instead, you receive a 20% tax credit on the interest paid, which is then deducted from your total tax bill.
What Taxes Do Landlords Pay in the UK?
Landlords in the UK face several types of taxation on their rental properties.
Income Tax on Rental Income
The primary tax landlord pay is income tax on their rental profits. Always remember that you will only pay tax on the profit you gain, not on the full amount you receive. Your rental income is combined with all other income sources to determine which tax band applies.
Real Life Example:
Sarah earns £40,000 from her job and makes £15,000 profit from renting out a property. Her total income is £55,000.
After the Personal Allowance of £12,570, she pays 20% tax on income up to £50,270, then 40% on the remaining £4,730 (£55,000 - £50,270). In the 2025/26 tax year, this results in approximately £9,432 in total income tax.
Estimating the income tax on high rental profits sometimes results in complex and miscalculations. Our rental income tax calculator does this heavy lifting for you in minutes.
Capital Gains Tax
When landlords sell a rental property, they may owe capital gains on the profit from the sale. CGT does not apply to the main residence due to Private residence relief. The first £3,000 of gains each tax year is tax-free. Landlords must report and pay CGT within 60 days of sale completion for UK residential properties.
