HMRC Record Keeping for Landlords

HMRC expects UK landlords to keep records of every pound of rental income and every allowable expense, along with the paperwork that backs each figure up, for at least five years after the 31 January submission deadline of the relevant tax year. That is longer than most people assume, and it catches out landlords who quietly delete bank statements or bin receipts once a return has been filed, on the assumption that filing is the end of the story.

This guide sets out exactly what HMRC expects you to keep, how long for, and how to build a system that holds up if HMRC ever asks questions, rather than a shoebox you hope never gets opened.

What HMRC expects you to keep

For rental income, HMRC wants evidence of what you actually received: bank statements showing rent landing in your account, a tenancy agreement setting out the agreed rent, and any letting agent statements if an agent collects rent on your behalf and deducts their fee before passing on the balance.

For expenses, you need a record of what was spent and why it counts as an allowable cost against your rental income, not a personal or capital cost. In practice that means:

• Invoices and receipts for repairs, maintenance, insurance, letting agent fees, accountancy fees and any other allowable running cost, showing the date, the amount and what the payment was for.
• Mortgage interest statements from each lender, since these feed into the Section 24 finance cost calculation even though the interest itself is no longer deducted directly from rental profit. Our Section 24 guide covers how that calculation works.
• A record of capital spending, kept separately from day-to-day expenses, because a new kitchen or an extension is treated differently for tax purposes to a like-for-like repair. Our landlord allowable expenses guide covers where that line sits.
• Evidence of ownership share, particularly for jointly owned property, since profit is normally split according to beneficial ownership rather than who happens to manage the property.
• Mileage and travel records, if you claim travel costs for visiting properties or meeting tenants and contractors, including dates, destinations and the purpose of each trip.

None of this needs to be paper. HMRC accepts digital copies, and for most landlords a scanned or photographed receipt, filed against the right property and date, is just as valid as the original, provided it is legible and complete.

How long to keep them

The headline rule for anyone with property or self-employment income is to keep records for at least five years after the 31 January submission deadline of the tax year they relate to. For the 2025-26 tax year, for example, the deadline to file online is 31 January 2027, so records for that year should be kept until at least the end of January 2032.

This is a longer window than the rule for someone with only employment income, who generally only needs to keep records for around 22 months after the end of the tax year, and the difference trips up landlords who assume a shorter, more familiar rule applies to them. If HMRC opens an enquiry into a return, the clock effectively extends until that enquiry is resolved, however long that takes, so it is worth erring on the side of keeping records slightly longer rather than deleting on the earliest date the rule technically allows.

If you have ever sold a rental property, keep the purchase and sale paperwork, and records of any capital improvements made along the way, for as long as you own it plus the standard record-keeping period afterwards, since this evidence is what your Capital Gains Tax calculation on sale will rely on. Our Capital Gains Tax on rental property guide covers what counts as an allowable cost against a gain.

Setting up a system that scales

The landlords who cope best with this requirement are rarely the most organised on paper. They are the ones who built a system once and then simply kept feeding it, rather than reconstructing a year of records from memory every January.

A few habits make the biggest difference:

• Keep rental banking separate from personal banking, so income and expenses do not need to be untangled from personal spending months later.
• File each receipt against the property and date it relates to as soon as it arrives, rather than piling everything into one folder and sorting it at year end.
• Categorise transactions close to the date they clear, while the detail is fresh, rather than trying to remember six months later whether a payment to a builder was for one property or another.
• Back up digital records somewhere other than a single device, since a lost phone or a failed hard drive is not an excuse HMRC accepts for missing evidence.
• Note anything unusual as it happens, such as a change of letting agent, a period of significant void, or a large one-off repair, so the context is captured while you still remember it rather than reconstructed later.

A worked example. Say HMRC opens an enquiry into a landlord's return three years after it was filed, querying a large repair cost claimed against rental profit that year. A landlord who filed the original invoice against the correct property and date can produce it in minutes, along with a note of what the repair actually involved, and the enquiry closes quickly. A landlord who cannot locate the invoice, or cannot recall which property it related to, faces a longer and more uncomfortable process, and may end up unable to support the claim at all, losing the deduction and potentially facing a penalty on top.

Common mistakes

• Treating filing as the finish line. The return being submitted does not mean the underlying records can be discarded; HMRC can still ask questions well after the deadline has passed.
• Keeping records by month rather than by property. A folder organised purely by date makes it hard to answer the question HMRC or an accountant actually asks: what happened with this specific property.
• Losing the distinction between capital and revenue costs. Filing every invoice in one undifferentiated pile makes it much harder to apply the correct tax treatment later, and mistakes here are one of the most common triggers for HMRC to ask further questions.
• Relying on a letting agent's records alone. Agents can close accounts, change systems or simply not retain data as long as HMRC expects you to, so keep your own copies rather than assuming someone else is holding them for you.
• Not keeping evidence for property no longer owned. A property you sold three years ago can still be the subject of a Capital Gains Tax check, and the records need to survive that sale, not disappear with it.
