Section 24: Mortgage Interest Restriction

Since April 2020, landlords can no longer deduct mortgage interest from rental income. Instead, you receive a basic rate tax credit.

How Section 24 Works

Old System (Pre-2020):

  • Deduct full mortgage interest from rental income
  • Pay tax on the net profit

Current System:

  1. Calculate rental profit WITHOUT deducting mortgage interest
  2. Pay tax on this higher profit
  3. Receive 20% tax credit on mortgage interest

Section 24 Impact Example

Rental income: £15,000 Mortgage interest: £8,000 Other expenses: £2,000

Basic Rate Taxpayer:

  • Deduct actual expenses, OR
  • Claim the £1,000 allowance (no receipts needed)

Should You Hold Property in a Limited Company?

Frequently Asked Questions

How much tax do I pay as a landlord UK?

You pay Income Tax on your rental profit at your marginal rate (20%, 40%, or 45%). You also pay CGT when selling (18% or 24%) and 3% extra stamp duty when buying.

What is Section 24 and does it affect me?

Section 24 restricts mortgage interest relief for individual landlords. You now receive a 20% tax credit instead of deducting interest. It affects higher rate taxpayers most significantly.

Do I need to register for Making Tax Digital as a landlord?

If your gross rental income exceeds £50,000, you must register for MTD ITSA from April 2026. The threshold drops to £30,000 in April 2027 and £20,000 in April 2028.

Can I offset rental losses against other income?

Rental losses can only be offset against future rental profits, not other income. Carry forward indefinitely until you have rental profits.

How quickly must I pay CGT when selling a rental property?

You must report and pay CGT within 60 days of completing the sale. Late reporting incurs penalties.
