What Is Rental Income Tax?
Rental income tax refers to the tax landlords must pay on the profits they earn from letting out property. In the UK, if you're renting out a property, whether it's a single flat, house, or a portfolio, you must report your income to HMRC. This income is added to any other income you earn and taxed under the normal income tax bands.
The amount of income tax on rental income you pay depends on your total annual income (including employment or self-employment), as well as your allowable expenses. You can use a rental income tax calculator like the one provided by Property Store to quickly estimate how much you’ll owe. Understanding how tax bands work, when you’re eligible for allowances, and what deductions apply is key to staying compliant and financially smart.
Who Should Use a Rental Income Tax Calculator?
A rental tax calculator is an essential tool for various types of property owners. If you're a landlord, whether professional or accidental, this tool helps estimate how much tax you might owe to HMRC. If you're unsure whether your rental income is taxable or if you’re trying to figure out your financial position before filing your tax return, the tax on rental income UK calculator is your go-to solution.

With the Property Store tool, you get clarity before it's time to file.

How to Use the Rental Income Tax Calculator
Using our UK rental income tax calculator is as simple as filling in a few fields and pressing a button. Here’s how:
-
Enter your annual rental income – This includes the total rent you receive from tenants over the year.
-
Add your annual employment salary – Your rental income is taxed alongside your other earnings.
-
Include your allowable expenses – Think repairs, letting agent fees, maintenance, etc.
-
Enter mortgage interest payments – You can claim a basic rate tax relief (20%) on this.
Once you click “Calculate”, the rental property tax calculator will instantly compute your estimated tax due, show you your post-tax rental profit, and generate a visual chart. You can also save your calculation to memory or reset to start fresh. Our tool is perfect for landlords who like clarity and control.
Understanding Your Results
Once your data is entered, the rental income tax calculator breaks down your tax summary into three clear components:
-
Taxable Rental Income – Your gross rental income minus allowable expenses and allowances.
-
Estimated Tax Due – Based on UK tax bands and your total income (salary + rental).
-
Post-Tax Income – The remaining profit after tax deductions.
You also get a pie chart visualising this breakdown, so you can see where your money goes. This is particularly useful for budgeting, planning investments, or preparing for a self-assessment tax return. With the tax on rent calculator, you don’t need to be a tax expert to understand your finances.
UK Rental Income Tax Bands (2025)
Tax on rental income in the UK is calculated based on your total annual income, which includes rental earnings. Here are the 2025–2026 tax bands:
-
£0 – £12,570: 0% (Personal Allowance)
-
£12,571 – £50,270: 20% (Basic Rate)
-
£50,271 – £125,140: 40% (Higher Rate)
-
Over £125,140: 45% (Additional Rate)
Your taxable rental income is added to your salary and taxed according to the total. This means someone earning £40,000 from a job and £15,000 from rent would be partly taxed at 20% and partly at 40%. Using our income tax on rental income calculator helps you understand exactly where you fall and how much tax you might owe.
What Expenses Can You Deduct?
One of the most important aspects of reducing your tax bill is knowing what expenses are deductible. When you use the landlord tax calculator, be sure to account for these:
-
Letting agent fees
-
Maintenance and repairs
-
Ground rent and service charges
-
Landlord insurance premiums
-
Legal and accounting fees
-
Utility bills (if paid by the landlord)
-
Mortgage interest (relief available at 20%)
These allowable expenses reduce your taxable rental income, meaning you could significantly cut your tax bill. The rental tax calculator on Property Store gives you the option to include these costs, offering a more accurate picture of your final tax liability.
Do You Need to Submit a Tax Return?
If you earn more than £1,000 in rental income in a tax year, you must report this to HMRC and may need to complete a Self-Assessment tax return. This applies even if you are PAYE employed. The tax on rental income UK calculator helps you assess whether you're above that threshold.
Even if you believe your rental income results in no tax due (due to expenses), you are still required to file if your income crosses the threshold. Using the rental income tax calculator ensures you're aware of your liability and helps avoid penalties from HMRC. At Property Store, we recommend using this tool annually to keep on top of your financial planning.
