Income tax on rental profits is going up. From 6 April 2027, landlords who own property personally will pay 24% at the basic rate, 44% at the higher rate and 49% at the additional rate, four percentage points more than today. The 28 October 2026 Budget added two points on top of the rise already set for that date. Mortgage interest relief rises to 24% too, so how much more you pay depends on how much of your rent goes on interest.

The new rental income tax rates

Basic rate20%24%+4 points
Higher rate40%44%+4 points
Additional rate45%49%+4 points
Mortgage interest relief20%24%+4 points

The rates apply to property income in England, Wales and Northern Ireland, and Scotland and Wales can set their own. They will be legislated in Finance Bill 2026 to 2027. Landlords who own through a limited company pay corporation tax instead, which did not change.

Worked examples

Illustrative examples, assuming all of the rental profit falls in one tax band and the landlord has other income that uses up the personal allowance.

LandlordTax 2026 to 2027Tax 2027 to 2028Extra a year
Higher rate, £20,000 rent, £5,000 costs, £10,000 interest£4,000£4,200£200
Higher rate, £20,000 rent, £5,000 costs, no mortgage£6,000£6,600£600
Basic rate, £12,000 rent, £3,000 costs, £4,000 interest£1,000£1,200£200

For the first example: rental profit before interest is £15,000. Today the tax is 40% of £15,000, £6,000, less 20% of the £10,000 interest, £2,000, giving £4,000. From April 2027 it is 44% of £15,000, £6,600, less 24% of £10,000, £2,400, giving £4,200.

Why mortgaged landlords pay less extra

Because the tax rate and the relief both rise by four points, the increase is roughly 4% of your profit after interest. A landlord whose rent mostly goes on interest sees a small rise; a landlord with no mortgage pays the full four points on their whole profit.

Your options before April 2027

  • Check every allowable expense is claimed. Letting fees, insurance, repairs, service charges and safety certificates all reduce your profit. Keep the records digital and complete.
  • Review weaker properties. A property that barely covers its costs today may not justify the extra tax. Compare keeping, improving, refinancing or selling.
  • Look at your mortgage timing. Rates, fees and fixed-rate end dates all feed into both cash flow and the interest relief.
  • Consider ownership, with advice. Joint ownership, company ownership and timing can change your tax, but transfers carry their own costs, such as capital gains tax and stamp duty. This needs a qualified tax adviser.
  • Get ready for Making Tax Digital if your qualifying income is over £30,000.

Common questions

Is income tax on rental income going up?

Yes. From 6 April 2027, property income is taxed at 24%, 44% and 49% instead of 20%, 40% and 45%, for landlords who own property personally in England, Wales and Northern Ireland.

How much more tax will landlords pay from 2027?

Roughly 4% of your rental profit after mortgage interest, because both the tax rates and the mortgage interest relief rise by four points. A higher-rate landlord with £20,000 rent, £5,000 costs and £10,000 interest would pay about £200 more a year.

What is the new rate for mortgage interest relief?

It stays aligned to the property basic rate, so it rises from 20% to 24% from 6 April 2027.

Does the rental income tax increase apply to limited companies?

No. Companies pay corporation tax, which stays at 19% to 25%.

Should I move my buy-to-let into a limited company?

It depends on your circumstances. Transferring property is usually treated as a sale at market value and can trigger capital gains tax, stamp duty and refinancing costs. Speak to a qualified tax adviser before deciding.
