Filing your tax as a landlord

If you receive rental income from UK property (including Furnished Holiday Lets), you may need to complete a Self Assessment return. This page explains when Self Assessment applies, how gains on disposals are handled, what to expect when reporting via SA100 + UK Property pages, the records you should keep, and quick answers to common questions. When you’re ready, file online with Ftax.

When it applies

You’ll usually file a Self Assessment return if you have taxable income from letting out a house, flat, room(s), or holiday accommodation. Points to note:

  • One UK property business. If you let more than one UK property, you normally report them together as a single UK property business (you don’t file per property).
  • Furnished Holiday Lets (FHL). FHLs are shown separately and have their own conditions.
  • Joint ownership. Report only your share of income and costs.
  • Allowances. Some landlords can use the property allowance instead of itemising costs. Check the current HMRC rules to see if it fits your situation.
  • Making Tax Digital (MTD). Landlords will need compliant digital records and software when MTD for Income Tax applies to them. 

Calculating gains when you sell a let property

Selling a rental property can create a Capital Gains Tax (CGT) liability. In many cases you must file a separate UK property CGT return and pay an amount on account shortly after completion, then also include the figures in your year-end Self Assessment.

  • Keep evidence of purchase and sale dates, costs (legal/agent fees, SDLT) and any capital improvements (not routine repairs).
  • For a full walkthrough, use Capital Gains for landlords in the Business section.
  • Disposals of a second home you never let are covered in Capital Gains for individuals.

Records to keep

Good records keep your tax fair and your filing stress-free:

  • Tenancy and agent documents: agreements, monthly statements, deposit info
  • Income evidence: rent received (per property if you manage it yourself)
  • Expense evidence: repairs/maintenance invoices, insurance, service charges, utilities you pay, agent/advertising fees
  • Finance costs: mortgage statements and interest summaries
  • Travel & admin: mileage logs for property visits; phone/internet apportionment notes if claimed
  • Capital items: invoices for improvements that enhance the property (kept for CGT)


Store your submitted return, HMRC receipt, and the Ftax calculation with your records.

FAQs

No. UK properties are usually reported together as one UK property business on your SA return. FHLs are shown separately.

Enter your share of income and costs. Keep evidence of the split (e.g. deed or agreement).

Finance costs are generally relieved via a tax credit rather than a full deduction. Enter the amounts as prompted; Ftax applies the current rules in your calculation.

You may need a separate UK property CGT return soon after completion and then include the figures in your year-end SA. See Capital Gains for landlords.

No. Use Ftax Cashbook (optional) or your own spreadsheets, then enter totals on the UK Property pages when you file.
