Landlord expenses: how to track and categorise them properly

Group your landlord expenses into the same categories HMRC uses for property income: rent, rates, insurance and ground rents; repairs and maintenance; non-residential loan interest and finance costs; legal, management and professional fees; costs of services, including wages; other allowable expenses; and residential finance costs, which get a basic-rate tax reduction rather than a deduction [1][2]. Only costs wholly and exclusively for the rental count [1]. Keep receipts, invoices and bank statements for at least 5 years after the 31 January filing deadline [1].

Landlord expenses are every cost of running your rental business, from boiler repairs to letting agent fees. Getting them right matters twice: it cuts your tax bill legally, and it keeps you on the right side of HMRC if your figures are ever checked. This guide is about the practical side: which categories to use, what records to keep, and a routine that stops receipts piling up.

Landlord expenses categories

The UK property pages of the Self Assessment return (SA105) group expenses into a handful of headings [2]. Making Tax Digital uses the same categories as Self Assessment [3], so if you set your records up this way now, you won't need to change them later.

CategoryTypical landlord expenses
Rent, rates, insurance, ground rentsCouncil tax and water rates you pay, landlord insurance, ground rent, service charges
Property repairs and maintenanceBoiler repairs, roof repairs, redecoration between tenants, like-for-like fixtures
Loan interest and other financial costsNon-residential property only; residential finance costs are separate
Legal, management and other professional feesLetting agent fees, accountant's fees, some legal fees
Costs of services provided, including wagesCleaners, gardeners, communal utilities you pay
Other allowable property expensesAdvertising, phone calls, stationery, business mileage
Residential property finance costsMortgage interest on residential lets: basic-rate tax reduction

What records to keep for landlord expenses

HMRC says the records you should keep could include rent books, receipts, invoices, bank statements and mileage logs for journeys solely for the property business [1]. You must also keep income from fully furnished lettings separate from unfurnished or part-furnished [1].

Records must be accurate, complete and readable, and kept for at least 5 years after the 31 January deadline for that tax year. HMRC can charge a penalty if they're not [1].

One business, many properties

If you let more than one UK property, HMRC treats them as one property business: income and expenses are added together and losses on one property offset profits on another [1]. Overseas property is kept separate [1]. You don't have to report expenses property by property, but tracking them that way tells you which lets are actually making money.

A monthly landlord expenses routine

  1. Pick one place for receipts. A folder, an app, or your landlord software. Snap paper receipts the day you get them.
  2. Use a separate bank account for rent and property costs. It makes the statements your main record.
  3. Once a month, categorise. Match each payment to a category and a property.
  4. Flag capital items. Improvements aren't deductible against rent, but keep them for Capital Gains Tax [1].
  5. Note mixed costs. If something is part personal, record only the business share [1].
  6. Check MTD dates. If you're in scope, quarterly updates are due 7 August, 7 November, 7 February and 7 May [3].

Landlord expenses spreadsheet: what columns to use

If you're not in MTD yet, a spreadsheet is fine. Useful columns:

  • Date
  • Property
  • Supplier
  • Description
  • Category (from the table above)
  • Amount
  • Paid from (account)
  • Receipt saved? (yes/no and where)
  • Capital or revenue

If MTD applies to you, you'll need bridging software to send spreadsheet figures to HMRC, or move to compatible software [4].

Where landlord expenses go missing

The usual culprit is repairs. A tradesperson sends an invoice by text, you pay by bank transfer, and six months later nobody can find the invoice or remember which property it was for. Small jobs are the worst, because they feel too minor to file.

Gaffy fixes that part. Each repair starts as a report from your tenant through the property's repair link, with photos. It sits in your maintenance inbox with its status and outcome, and you log what it cost against that property. Store the invoice in the property's vault and it's all in one place at tax time. Gaffy isn't accounting software, but it keeps the repair line clean. £12 a month for up to 5 properties, first month free.

Landlord expenses checklist by category

Use this as a prompt when you review a year's spending. Whether each item is allowable depends on the facts; see allowable expenses for landlords.

  • Rates and insurance: council tax and water rates in void periods or where included in rent; landlord buildings, contents and liability insurance [1].
  • Repairs: boiler call-outs, plumbing, roofing, redecoration between tenants, like-for-like fixture replacements [1].
  • Professional fees: letting agent or management fees, accountant's fees, some legal fees [1].
  • Services: cleaning of communal areas, gardening, utilities you provide [1].
  • Other: advertising for tenants, phone calls and stationery for the rental business, business mileage [1].
  • Replacement items: replacing furniture or appliances may qualify for replacement of domestic items relief [1].
  • Finance: residential mortgage interest is handled as a basic-rate tax reduction [1].

Common landlord expense mistakes

  • Claiming the whole mortgage payment rather than handling only the interest [1].
  • Treating an improvement as a repair [1].
  • Losing small invoices, which add up over a year.
  • Mixing personal and property spending in one account.
