A landlord’s accounting records should be organised the way the tax system thinks: property by property, income and costs together, with the paperwork behind every figure. Keep one record set per property per year, plus a small general set for costs that span the portfolio. This checklist sets out what goes in each. Landlords who keep this structure turn every filing into a compilation job. Landlords who keep a shoebox and a mortgage app spend a fortnight on it, and still miss things.

Where you keep the records now matters too

Making Tax Digital for Income Tax is being phased in for landlords and the self employed. If your qualifying income is above the level HMRC has set for your year, you must keep your records digitally in compatible software and send quarterly updates as well as a year end return. Qualifying income is measured on gross rents and self employed turnover before any expenses come off, so the test is not about profit. Check the current dates and income levels on GOV.UK, because the phasing runs across several tax years. The checklist below still describes what to keep; for a landlord already in scope, a shelf of paper folders is no longer where it can live.

Every landlord, including the accidental ones

Records matter from the first let, whether that is a single inherited flat or a former home you kept when you moved in with a partner. There are small automatic exemptions, including one for letting a room in your own home and a small allowance for low property income, so check on GOV.UK whether either applies to you. If neither does, the record keeping duty is yours from day one. HMRC’s obligations for landlords are set out in the GOV.UK guidance on renting out a property, and they do not wait for you to feel like a property business.

What accounting records should a landlord keep per property?

For each property, each tax year, keep:

  • A rent record: amounts due, amounts received, dates, and any arrears position
  • The tenancy agreement and any renewals or variations
  • Deposit protection certificates and correspondence
  • Every cost invoice and receipt: repairs, insurance, ground rent and service charges, certificates and inspections, advertising, legal and professional fees
  • Mortgage statements showing interest charged for the year
  • Letting agent statements, complete for the year
  • Mileage or travel notes for property visits, with dates and purposes

Costs need their paperwork whatever their eventual tax treatment, because treatment depends on the facts of each item and year, and the invoice is what lets your accountant judge it. That judgement question, especially for works on the property, is one we cover in bookkeeping for rental property businesses.

Agent statements are not a substitute for your own records

If an agent collects your rent, their monthly statements are essential records: they show gross rent, their fees and anything they paid out on your behalf. But reconcile them to your bank, because what lands in your account is the net figure and the difference is itself part of your records. Keep every statement for the year, chase missing months immediately, and remember the legal responsibility for records is yours under the retention rules in the GOV.UK guidance on keeping your pay and tax records, not the agent’s.

Deposits: money that is not income

A tenant’s deposit is not rent and should never appear in your income records while it remains protected and returnable. Record it separately, with the protection paperwork attached. Only if part of it is properly retained at the end of a tenancy does it become something your tax records need to account for, and the deduction paperwork should be filed when that happens, not reconstructed later.

The general folder: portfolio-wide items

Some records do not belong to one property: landlord insurance covering several lets, professional subscriptions, software costs, accountancy fees, and loan arrangements secured across the portfolio. Keep them in a general folder and let your accountant allocate them. Jointly owned properties need a note of ownership shares and any formal arrangements between the owners, a subject with enough traps that we treat it separately in preparing property income records for an accountant.

Gaps that cost landlords at return time

  • Rent tracked only through a bank app, with no record of what was due versus received
  • Repairs paid in cash to tradespeople with no invoice
  • Agent statements missing for the months when problems happened
  • Mortgage interest read from a payment total that mixes capital and interest
  • No record of periods the property stood empty, and what was spent readying it

When records become a service rather than a habit

One or two properties reward a disciplined filing habit. Once quarterly updates start, or the count grows, or a company structure enters the picture, monthly bookkeeping starts to beat annual assembly. Our bookkeeping service runs per-property records through the year, and what drives a landlord accountant’s cost explains how record quality feeds directly into fees.

Frequently asked questions

Do I need to keep records if the rent barely covers the mortgage?

Yes. Cash left over and taxable profit are different calculations, and only records can show which position you are actually in. Assuming “no profit, no paperwork” is among the most expensive mistakes a new landlord makes.

How long should a landlord keep property records?

At least the retention periods HMRC publishes, and in practice longer for anything relating to the purchase, improvement or ownership structure of a property. Keep purchase, improvement and ownership paperwork for as long as you own the property, and then for as long as the records behind the tax return reporting the sale must be kept. We suggest keeping it longer than the minimum, because those documents are what evidence the gain or loss if HMRC asks.

Should rent go into a separate bank account?

For an individual landlord it is not mandatory, but a dedicated account makes the rent record, the reconciliation and the year-end handover dramatically easier. For company-owned property, the company must have its own account regardless.

What records do I need for a property I let furnished?

The same checklist, plus records of furniture and appliance purchases and replacements, with invoices and dates. The treatment of that spending depends on the circumstances of each item, so the paperwork is what keeps your options open.
