Whether you’re already renting out a property or just about to dip your toes into the Buy-to-Let world, one of the first things you’ll want to understand is: how much tax will I need to pay on the rental income?
Let’s break it down clearly, with extra insight on rental income in the UK.
The Main Taxes Landlords Face
Owning property in the UK can be profitable, but it is also subject to a range of tax obligations that all landlords need to be aware of. Whether you are a first-time investor or an experienced portfolio holder, knowing when and how these taxes apply can enable you to plan, be compliant, and avoid costly surprises.
UK landlords typically face three main types of taxation: Stamp Duty Land Tax (SDLT) on the acquisition of a property, Income Tax on rents, and Capital Gains Tax (CGT) on a disposal. Each has its own rules, rates and reliefs.
In this article, we’ll focus specifically on Income Tax on rental income, what it is, who it applies to, how it’s calculated, and what you can do to manage your tax bill effectively. Stamp Duty Land Tax (SDLT) and Capital Gains Tax (CGT) can be explored separately through our detailed guides.
You’re Taxed on Profit, Not the Full Rent
A common misconception among new landlords is that HMRC will tax you on the entire amount of rent you receive. In reality, you’re only taxed on your rental profit, the amount left after deducting allowable expenses from your rental income.
Rental Profit Formula
Rental Profit = Rental Income – Allowable Expenses
Typical allowable expenses include:
Letting agent fees and management charges
Repairs and routine maintenance (but not property improvements)
Landlord insurance premiums
Utility bills and council tax (if you pay them instead of the tenant)
Legal and accountancy fees related to the rental business
Understanding this distinction is key to calculating your tax liability accurately and ensuring you claim every deduction you’re entitled to.
Mortgage Interest Works Differently Now
Before April 2020, landlords could deduct their full mortgage interest payments from rental income when calculating taxable profit. Those days are gone.
Today, you can’t deduct mortgage interest as an expense. Instead, you receive a 20% tax credit on the lower of the following:
Finance costs, or the mortgage interest paid
Property business profits - i.e., the profits of the property business in the tax year, after accounting for any losses carried forward
Adjusted total income - i.e., the individual's total revenue minus the personal allowance
The restriction is put in place to ensure that the reduction is not used to create a tax refund.
Example
If you are a higher-rate taxpayer and pay £8,400 in mortgage interest during the tax year, you’re entitled to a tax credit of:
20% × £8,400 = £1,680
This particularly affects those who are in higher and additional taxpayers.
If 20% of your mortgage interest seems more than the profit you earn, or you are having problems finding out, consider seeking help.

Rental Profit Is Added to Your Other Income
Once you work out your rental profit, it’s added to your other income (salary, dividends, etc.) and taxed at your marginal income tax rate:
Total Income Band | Tax Rate on Rental Profit |
|---|---|
£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) |
Worked Example
Scenario
Tax Calculation:
If You Own the Property Through a Company
If you own your rental property through a limited company, the tax rules differ significantly from personal ownership. Instead of Income Tax, the company pays Corporation Tax on its rental profits.
Corporation Tax Rates (for 2025/26):
- 19% on profits up to £50,000 (small profits rate)
- 25% on profits over £250,000 (main rate)
- For profits between £50,000 and £250,000, marginal relief applies. This means the tax rate gradually increases from 19% to 25% as profits rise, creating a tapered rate for medium-sized profits.
This tiered system ensures smaller companies pay a lower tax rate, while larger profits are taxed more heavily.
Non-Resident Landlords
Even if you live abroad, you must pay UK Income Tax on your UK rental profits under the Non-Resident Landlord Scheme (NRLS).
Letting agents are required to deduct 20% tax from the rent they collect unless you have HMRC approval under NRLS, so applying for an NRL1 (or the relevant form, see below) allows you to receive the full rent.
To get full rent, you need to ask for HMRC approval by sending a form:
These forms require information about the property and the letting agent.
You don't need to fill out the form by yourself. You can authorise us as your agent, and we will submit the form to HMRC. Once approved, HMRC will register you for Self-Assessment, and you must file your tax returns annually.
If you meet any of the following conditions, you will be entitled to a personal allowance of £12,570, even as a non-UK resident:
You might also get it if it’s included in the double-taxation agreement between the UK and your country of residence (personal allowance for non-resident landlords).
Key Takeaways
Conclusion
Choosing whether to hold property personally or through a company can make a big difference to your tax bill.
The right choice depends on your income level, long-term goals, and future sales plans.
