Section 24 Explained
Section 24 Explained
Since April 2020, landlords can only claim a 20% tax credit on mortgage interest, not a full deduction. Higher-rate taxpayers effectively pay tax on rental income before mortgage costs.
Tax Bands for Rental Income
Rental profit is added to your employment income. This can push you into higher tax bands: 20% basic rate, 40% higher rate, or 45% additional rate. Section 24 amplifies this impact.
Allowable Expenses
Deduct maintenance, insurance, letting agent fees, and other property costs from rental income. Mortgage interest is no longer fully deductible - only a 20% tax credit applies.
Example Tax Calculations
| Employment Income | Rental Income | Rental Expenses | Rental Profit | Est. Tax Due |
|---|---|---|---|---|
| £25,000 | £12,000 | £3,000 | £9,000 | £1,800 (20%) |
| £40,000 | £18,000 | £4,000 | £14,000 | £4,800 (34%)* |
| £60,000 | £24,000 | £6,000 | £18,000 | £7,200 (40%) |
| £80,000 | £30,000 | £8,000 | £22,000 | £8,800 (40%) |
| £130,000 | £36,000 | £10,000 | £26,000 | £11,700 (45%) |
* Example assumes some mortgage interest. Section 24 can cause effective tax rates between bands. These are simplified estimates.
Special Considerations
Property Allowance (£1,000)
If your rental income is under £1,000 per year, you don't need to report it. If over £1,000, you can claim either the allowance or actual expenses - whichever is higher.
Wear and Tear / Replacement Relief
The 10% wear and tear allowance was abolished in 2016. You can now only deduct the actual cost of replacing furnishings, appliances, and furniture in furnished lettings.
Furnished Holiday Lettings Changes
From April 2025, the Furnished Holiday Lettings regime is being abolished. This removes beneficial tax treatment including full mortgage interest relief and capital allowances.
Record Keeping Requirements
Keep records of all rental income and expenses for at least 5 years after the 31 January submission deadline. HMRC can investigate and charge penalties for poor record keeping.
Critical: Section 24 Means Higher-Rate Taxpayers Can't Fully Deduct Mortgage Interest
Section 24 restricts mortgage interest relief to a 20% tax credit only - you can no longer deduct mortgage interest at 40% or 45%. This means higher-rate taxpayers effectively pay tax on rental income before mortgage costs are considered. Many landlords now use limited company structures to avoid Section 24. Always consult an accountant for tax planning advice.
