Landlord Bookkeeping: What Rental Records HMRC Expects

Rent lands in your bank account, a plumber sends an invoice to your personal email, and the letting agent's statement sits in a different inbox. Six months later, nobody can say exactly what one property earned or cost. That is how most landlord bookkeeping problems start: records scattered across four places.

When Self Assessment season arrives, you are left guessing, and guessing costs landlords money: expenses forgotten, figures you cannot back up, and a return filed late because the paperwork took weeks to untangle. The fix is a small set of records, kept in one place and updated monthly. Here is what HMRC expects, and how to set it up this week.

What landlord bookkeeping means in practice

Landlord bookkeeping is simply a complete, dated record of the money coming in and going out of your property business. HMRC does not ask for anything fancy. It asks that your records be accurate, complete and readable, so the figures on your tax return can be checked. If you cannot produce a record for a figure, HMRC can challenge it — and it can charge a penalty if your records are not up to scratch.

One point that trips up new landlords: if your gross rental income is £1,000 or less in a tax year, the property allowance usually means you do not need to declare it. Above £1,000, you need to report it, and above £2,500 of profit you will normally do that through Self Assessment.

What records HMRC expects you to keep for landlord bookkeeping in the UK

Think of your records in three piles: income, expenses, and proof of both.

Income records

• Rent received, property by property, with the date paid and the tenant it came from. A short rent log matching each payment to a property and a month makes an enquiry far easier to answer than bank statements alone.
• Letting agent statements, showing rent collected, fees deducted and amounts passed to you. Keep the statement, not just the net payment that hit your account.
• Other property income, such as charges for services you provide to tenants, and any deposit amounts kept at the end of a tenancy.

Expense records

• Repairs and maintenance invoices and receipts, with the property and date noted on each one.
• Letting agent and management fees, insurance premiums, ground rent and service charges.
• Mortgage interest statements. For residential property, mortgage interest now gives a basic-rate tax reduction on finance costs rather than a deduction from rental income. Keep the statements either way.
• Utility and council tax bills you pay during void periods, and mileage logs for journeys made solely for your property business.

The records most landlords forget

• Capital spending. A new boiler or an extension is not allowable against rental income, so it is tempting to bin the invoice. Do not — it may reduce a Capital Gains Tax bill when you sell.
• A separate bank account for rent. If rent and personal spending share one account, separating them later is painful. A dedicated rental account is the single easiest habit to adopt.
• Deposit protection paperwork and check-in/check-out inventories. These settle deposit disputes and back up any deposit income or deductions on your return.

How long to keep your rental records

For landlords filing Self Assessment, keep records for at least five years after the 31 January submission deadline for the tax year in question. Records for 2025/26, with a filing deadline of 31 January 2027, should therefore be kept until at least 31 January 2032. If you file late, or if HMRC opens an enquiry, keep everything until that is resolved. HMRC's guidance on working out your rental income sets out the record list in full.

A monthly routine that takes about twenty minutes

Touch your records little and often. Once a month:

1. Check every rent payment arrived, and log any arrears against the right property and month.
2. Photograph or scan every paper receipt and invoice, and file it under the property and the month.
3. Record each expense with the supplier, the property and what it was for. "Plumber — 12 Oak Road — leaking tap" is a record; "plumber £180" is a puzzle in January.
4. Reconcile the month against your bank statement so nothing is missing or double-counted.

Done monthly, this takes about twenty minutes per property.

Getting ready for Making Tax Digital

From 6 April 2027, landlords with qualifying income over £30,000 in 2025/26 must keep digital records and send HMRC quarterly updates under Making Tax Digital for Income Tax. Qualifying income is gross rent (plus any self-employed income) before expenses. The quarterly updates are summaries, not your receipts — but they must be built from records that are already digital and properly categorised. If you still run your lets from a shoebox, now is the time to move to proper software or a bookkeeper. You can see what our bookkeeping service covers, including rental income.

What to do this week

• Open a separate bank account for rent and property spending, if you do not already have one.
• Gather this tax year's records into one folder — and chase anything missing while copies are still easy to get.
• Set a monthly 20-minute slot for the routine above, and stick to it for one month.
• Check whether you are in scope for Making Tax Digital from April 2027 by adding up your gross rental income for 2025/26. If it is over £30,000, plan the move to digital records now.
• Do not throw anything away — even capital invoices you cannot claim this year may matter later.

Good landlord bookkeeping means knowing, at any moment, what each property actually made you — and being able to prove it. Set up the folder, the separate account and the monthly slot this week.
