Letting out a property can be a rewarding source of income, but it also comes with tax responsibilities that many new landlords underestimate. HMRC expects rental income to be reported accurately and on time.
The rules can feel confusing, especially around expenses, mortgage interest and what happens when you sell. Understanding the basics early helps you avoid mistakes and keep more of your rental profit.
In this guide we explain what counts as rental income, what you can deduct and how to report it correctly.
Yes, rental income is taxable in the UK, but landlords can deduct many costs and use reliefs so that tax is paid only on genuine profit.
What Counts as Rental Income?
Rental income is more than just the monthly rent. You generally need to include:
– Rent received from tenants
– Charges for services you provide, such as cleaning or gardening
– Payments for the use of furnishings or equipment
– Deposits you keep to cover damage or unpaid rent
Tax is based on your profit, which means income minus allowable expenses, not the total rent collected.
Property Allowance or Actual Expenses?
If your gross property income is £1,000 or less in a tax year, the property allowance may mean you do not need to report it or pay tax on it. If your income is higher, you can choose between deducting the £1,000 allowance or deducting your actual expenses, but not both. Typical allowable expenses include:
– Letting agent and management fees
– Repairs and maintenance (but not improvements)
– Landlord insurance
– Accountancy fees
– Utility bills, council tax and service charges you pay
– Ground rent
Keeping clear records of every cost is essential, because HMRC can ask to see evidence.
"Good records are a landlord's best protection. When every expense is documented, claiming it is simple and defending it is easy."
Mortgage Interest and Section 24
Individual landlords with residential properties can no longer deduct mortgage interest from their rental income. Instead, they receive a tax reduction worth 20% of the interest paid. For higher-rate taxpayers this can noticeably increase the tax bill, so it is important to plan ahead. Different rules apply to properties held in a limited company.
Selling a Rental Property
When you sell a rental property for more than you paid, you may have to pay Capital Gains Tax on the gain. For UK residential property sales where tax is due, you generally need to report and pay within 60 days of completion. You also have an annual exempt amount (currently £3,000) before tax applies. Keep records of the purchase price, improvement costs and selling costs, as they reduce your taxable gain.
