What rental income includes

Who this guide is for: For landlords working out what counts as taxable property income and whether the property allowance or actual expenses is better.

Rental income is money you receive from letting property — usually rent, plus certain other taxable receipts from the property business.

You pay Income Tax on profits after allowable expenses or after claiming the property allowance where you choose that route. For finance costs and the wider landlord picture, see Buy to Let Tax Explained.

Property allowance versus expenses

Typical allowable costs

  • Letting agent fees and advertising
  • Landlord insurance
  • Repairs and maintenance (not capital improvements)
  • Accountancy fees for the property business
  • Ground rent and service charges you pay as landlord

Residential mortgage interest is restricted for many individual landlords — see Buy to Let Tax Explained for the detail. For the wider cluster, start at the property tax hub.

Frequently asked questions

Does the property allowance work like the Trading Allowance?

Yes in structure: you can usually deduct a £1,000 property allowance instead of actual allowable expenses for property income, subject to the GOV.UK conditions. You cannot claim both for the same income. You also cannot use the property allowance if you claim the residential finance-cost tax reducer for mortgage interest.

Is rent-a-room the same thing?

No. Rent-a-room is a separate relief for letting furnished accommodation in your home. Different limits and conditions apply.

What counts as rental income?

Typically rent received, tenant charges you keep, and certain other receipts from the property business. Deposits held for tenants are not income while refundable.

Can I claim repairs?

Like-for-like repairs are often allowable. Improvements that enhance the property are usually capital and not deductible against rent.
