Every UK landlord with rental income above the £1,000 property allowance must complete a self-assessment tax return reporting their rental profits. This annual landlord accounts template gives you a structured profit and loss spreadsheet to record all income and allowable expenses across your portfolio — making self-assessment preparation straightforward and ensuring you capture every legitimate deduction.

The template covers up to five properties on individual sheets, with a portfolio summary that rolls up all income, expenses, mortgage interest, and Section 24 tax credit calculations. The summary sheet produces a single taxable profit figure and estimated tax liability — the exact inputs you need for the UK Property (SA105) pages of your self-assessment return.

It is not a substitute for professional accountancy advice — particularly for more complex situations such as furnished holiday lets, mixed personal and commercial use, or jointly owned properties. But for landlords with straightforward portfolios of one to five standard residential lets, it provides a clear, consistent framework for annual bookkeeping.

What does the landlord accounts template include?

  • Income section — gross rent received (April–April), any arrears recovered, and other income (e.g. insurance claims received for repairs)
  • Allowable expenses — pre-formatted rows for letting agent and management fees, repairs and maintenance, buildings insurance, gas safety, EICR, advertising, accountancy, ground rent, service charge, and travel
  • Finance costs section — mortgage interest separated from other expenses, with automatic 20% Section 24 credit calculation
  • Net profit calculation — rental income minus allowable expenses (excluding finance costs) = taxable profit before Section 24
  • Tax liability estimate — at basic (20%), higher (40%), or additional (45%) rate with Section 24 credit applied
  • Portfolio summary sheet — consolidates all properties into single totals for the SA105 return
  • Notes column — record invoice reference, date paid, and supplier for each expense line to support HMRC enquiries

Who needs this template?

This template is designed for UK landlords who manage their own self-assessment bookkeeping, or who want to prepare organised records before passing them to an accountant. It is particularly useful for:

  • Individual landlords with 1–5 properties filing a UK Property SA105 self-assessment return each year
  • Landlords affected by Section 24 who want to see clearly how the mortgage interest credit impacts their actual tax bill
  • Landlords switching accountants who need a standard format to hand over organised records rather than a box of receipts
  • New landlords setting up a bookkeeping system for the first time and wanting to understand what needs to be tracked

Landlord Accounts FAQs

PropertyBrain Editorial Team — cross-checked against HMRC property income guidance. Last verified: July 2026. This is not tax advice — always consult a qualified accountant for your personal position.
What expenses can a landlord deduct for tax?

UK landlords can deduct: letting agent and management fees, repairs and maintenance (not improvements), buildings and contents insurance, gas safety certificates and EICR costs, accountancy fees, motor expenses for property-related travel, advertising and void costs, ground rent and service charges, and professional subscriptions. Mortgage interest is no longer directly deductible — instead, landlords receive a 20% tax credit on finance costs under Section 24. Capital expenditure (improvements, extensions, new boilers replacing like-for-like for the first time) is not deductible but may qualify for capital allowances or reduce capital gains tax on sale.

How do I prepare landlord accounts for self-assessment?

To prepare landlord accounts for self-assessment, gather all rental income received in the tax year (April to April), all allowable expenses, and your total mortgage interest paid. Calculate your net profit (income minus allowable expenses) — this is your taxable rental income. Then calculate your tax liability at your marginal rate, applying the 20% Section 24 finance cost credit against your bill. Report figures on the UK Property pages (SA105) of your self-assessment return. Keep receipts for all expenditure for six years.

What is the Section 24 finance cost credit?

The Section 24 finance cost credit is a 20% tax reduction on mortgage interest and other finance costs paid by UK landlords. Introduced by the Finance (No. 2) Act 2015, it replaced the pre-2017 system under which landlords could deduct the full mortgage interest from rental income before calculating their tax liability. The credit is applied after calculating the tax on the full rental profit. For basic rate taxpayers, the effect is broadly neutral. For higher and additional rate taxpayers, it represents a significant increase in tax burden.

Important note

This template is provided for guidance only and does not constitute tax advice. Tax rules for landlords are complex and change frequently — including allowable expenses, Section 24 rules, furnished holiday let legislation, and HMRC reporting requirements. Always consult a qualified accountant or tax adviser for your personal position. Keep all receipts and bank statements for a minimum of six years in case of an HMRC enquiry. PropertyAlert (Eightfinity Ltd) accepts no liability for any errors in your tax return arising from use of this template.
