How Much Tax Do I Pay on Rental Income in the UK? (2026 Guide)

If you earn income from renting out property in the UK, you’ll usually need to pay tax on your rental profits. But how much tax do you actually pay on rental income?

The answer depends on:

• Your total income

• Your tax band

• Your allowable expenses

• Whether you own the property personally or through a limited company

In this guide, we explain exactly how rental income tax works in the UK for 2026 and show you how to estimate what you might owe.

Do You Pay Tax on Rental Income?

Yes. Rental income is taxable in the UK.

If you rent out:

• A buy-to-let property

• A former main residence

• A room in your home (outside Rent-a-Room limits)

• Commercial property

You must declare the income to HMRC through Self Assessment.

However, you are taxed on profit, not turnover.

What Counts as Rental Income?

Rental income includes:

• Monthly rent payments

• Non-refundable deposits

• Fees paid by tenants

• Payments for services (cleaning, gardening, utilities if included)

You must declare the total received in the tax year (6 April to 5 April).

How Is Rental Profit Calculated?

You don’t pay tax on the full rent received. You pay tax on:

Rental Income – Allowable Expenses = Taxable Profit

Common Allowable Expenses

You can usually deduct:

• Letting agent fees

• Repairs and maintenance (not improvements)

• Landlord insurance

• Council tax (if paid by you)

• Utility bills (if paid by you)

• Ground rent and service charges

• Accountant fees

• Replacement of domestic items (like sofas or appliances)

You cannot deduct:

• Mortgage capital repayments

• Property improvements (extensions, upgrades)

What About Mortgage Interest?

Since the mortgage interest relief changes introduced in 2020, landlords can no longer deduct mortgage interest as an expense.

Instead, you receive a 20% tax credit on your mortgage interest.

This makes a major difference for higher-rate taxpayers.

Example:

If:

• Rental profit before mortgage interest = £15,000

• Mortgage interest = £10,000

Old system: You would have been taxed on £5,000
New system: You are taxed on £15,000 and receive a 20% credit on £10,000 (£2,000)

If you’re a 40% taxpayer, this increases your tax bill.

Rental Income Tax Rates (2026)

Rental profit is added to your other income and taxed at normal income tax rates.

UK Income Tax Bands:

Your rental profit is stacked on top of your salary or other income.

Example 1: Basic Rate Taxpayer

Sarah earns:

• £30,000 salary

• £8,000 rental profit

Total income: £38,000

She remains in the basic rate band.

Rental tax = £8,000 × 20% = £1,600

Example 2: Higher Rate Taxpayer

James earns:

• £55,000 salary

• £12,000 rental profit

His rental income pushes him further into higher rate.

Rental tax = £12,000 × 40% = £4,800

(Plus mortgage interest restriction impact.)

What If You Own Property Jointly?

Rental profit is usually split according to ownership percentage.

• Married couples default to 50/50 unless a Form 17 election is filed.

• Unmarried owners are taxed based on actual ownership share.

Each owner reports their share via Self Assessment.

What About the £1,000 Property Allowance?

If your total rental income is under £1,000 per year, you may qualify for the Property Allowance.

You can either:

• Deduct £1,000 instead of expenses, or

• Use actual expenses (whichever is more beneficial)

If rental income is below £1,000 total, you may not need to declare it.

How Do You Pay Rental Income Tax?

You must:

1. Register for Self Assessment (if not already registered)

2. Submit a tax return by 31 January

3. Pay any tax due

If your tax bill exceeds £1,000, HMRC may require Payments on Account for the following year.

This catches many new landlords by surprise.

Do Limited Companies Pay Less Tax on Rental Income?

Some landlords operate through a limited company.

Limited Company Tax:

• Profits taxed at Corporation Tax (currently 25%)

• Mortgage interest fully deductible

• Dividends taxed when withdrawn

This can be more tax efficient for higher earners but involves:

• Higher mortgage rates

• Additional accountancy costs

• Administrative burden

Professional advice is strongly recommended before incorporating.

What If You Sell the Rental Property?

When you sell, you may owe Capital Gains Tax (CGT).

CGT depends on:

• Gain made

• Ownership period

• Whether it was ever your main residence

• Your tax band

If you’re selling a former home, Private Residence Relief may apply.

You must report residential property gains within 60 days of completion.

How to Reduce Rental Income Tax Legally

Some common tax planning strategies include:

• Maximising allowable expenses

• Pension contributions to reduce tax band

• Spousal ownership planning

• Considering limited company structures

• Timing large repair works

Always ensure planning is compliant with HMRC rules.
