What Records Should UK Landlords Keep and for How Long?

Landlord record keeping is a legal duty, not just good housekeeping. For an individual it sits in section 12B of the Taxes Management Act 1970; for a company landlord it sits in paragraph 21 of Schedule 18 to the Finance Act 1998, with section 388 of the Companies Act 2006 separately governing company accounting records. This guide sets out what to track day to day, how long each record has to survive, and how to build a system that holds up under an HMRC enquiry and under Making Tax Digital.

For the penalty bands, the discovery-window detail and the voluntary-disclosure routes if records are already missing, see our companion guide on record retention, voluntary disclosure and failure to notify. For the digital-software mechanics of MTD, see MTD record keeping for landlords. For the records that establish a property's base cost on sale, see CGT record keeping for property sales.

How long must you keep landlord records?

The single most common question is how long records have to be kept, and the answer turns entirely on how you hold the property. The periods below are anchored to statute, not rules of thumb.

Record type / holder	Minimum retention period	Statutory basis
Individual landlord (property business)	5 years after the 31 January filing deadline for the tax year	TMA 1970 s.12B(2)(a)
Limited company landlord	6 years from the end of the accounting period	FA 1998 Sch 18 para 21 (company tax records); CA 2006 s.388 separately requires accounting records (3 years private, 6 years public)
Records where an HMRC enquiry is open	Until the enquiry and any appeal are finally resolved	Practical (enquiry overrides the standard period)
Capital gains base-cost records	Until at least 5 years after the 31 January following the year of disposal	TMA 1970 s.12B (CGT computation)
Losses carried forward	Until the loss is fully used, then the normal period	Practical (loss support)

For an individual landlord, section 12B requires records to be preserved until the fifth anniversary of the 31 January next following the year of assessment. Because letting property is treated as carrying on a business, this is the 5-year limb at s.12B(2)(a), not the shorter one-year limb that applies to people with only simple, non-business income.

Worked example. Records supporting your 2026/27 return are filed by 31 January 2028. The fifth anniversary of that deadline is 31 January 2033, so you must keep the 2026/27 records until then. We recommend a 7-year floor (one year beyond the statutory minimum) as a buffer against the extended assessment windows discussed below.

For a limited company landlord, the tax records must be kept for 6 years from the end of the accounting period they relate to, under paragraph 21 of Schedule 18 to the Finance Act 1998. That period runs longer where a transaction spans several accounting periods, where an asset will last beyond six years, or where a return was filed late. Section 388 of the Companies Act 2006 separately requires accounting records to be kept (3 years for a private company, 6 for a public one), but the 6-year tax-record duty is the one that matters in an HMRC enquiry.

Do not confuse the 5-year and 6-year periods. The 6-year figure is corporation tax and company law; it is not the income-tax period for an individual. If you read elsewhere that an individual landlord must keep records for six years, that is wrong: the individual period is five years under s.12B.

What rental income records does HMRC require?

HMRC opens most property enquiries the same way, by comparing declared income against the bank account. Income records that reconcile cleanly are your first line of defence, so for each property keep a complete trail of every receipt.

• Tenancy agreements and rent schedules for each let
• Bank statements showing rent received, kept per property where possible
• Rent arrears, recovery action and any rent guarantee insurance payouts
• Deposits retained at the end of a tenancy for damage or cleaning (these are taxable income) and deposit-scheme protection records
• Ground rent received where you own the freehold
• Income from parking spaces, storage or aerials
• Holiday-let booking-platform statements and occupancy records
• Service charges and utilities recharged to tenants, with the underlying supplier bills

Keep the records property by property. A landlord with three flats who pools everything into one spreadsheet cannot easily prove which receipt belongs to which property when HMRC asks, and that is where estimated assessments and disallowed expenses creep in.

Property management records landlords most often overlook

The income and expense ledger is the part landlords remember. The records that trip people up are the property management records that feel administrative rather than financial, yet decide whole arguments in an enquiry or on sale. These are the most commonly missing items in the files we are asked to defend:

• The completion statement and SDLT (or LBTT/LTT) certificate from purchase. Without it, the base cost on a future sale is open to challenge and the gain can be overstated.
• Dated photographs taken before and after work. A photograph is what separates a deductible repair from a capital improvement when the description on an invoice is ambiguous.
• Mileage logs for property visits, with dates, destinations and purpose. Travel claimed without a contemporaneous log is routinely disallowed.
• Safety and compliance certificates: gas safety, EICR electrical reports, EPC, and HMO fire-safety records. These prove both the expense and that the property was lawfully let.
• Deposit-protection scheme records and prescribed-information confirmations, which matter for both tax and possession.

None of these feels urgent in a given month, which is exactly why they go missing. Capturing them at the point each one is created costs minutes; reconstructing them years later, if it is possible at all, is slow and rarely complete.

Property expense and capital-expenditure records

Expense records are what turn the deductible expenses you are entitled to into an actual reduction in your tax bill. The biggest beginner error is mixing up revenue (running-cost) expenses with capital expenditure, so keep the two streams separate from day one.

Revenue expense records (deducted against rental profit)

• Letting-agent and management fees, advertising, tenant referencing and credit checks
• Repairs and maintenance invoices from contractors, with receipts for materials
• Mortgage interest statements and finance costs (relieved as a basic-rate credit under Section 24, not as a full deduction)
• Landlord insurance premiums and professional fees
• Gas-safety, electrical and EPC compliance costs
• Mileage logs for property visits (dates, destinations, purpose)

Capital-expenditure and base-cost records (used on sale, for CGT)

• Acquisition: purchase contract, completion statement, Stamp Duty Land Tax certificate (or LBTT in Scotland, LTT in Wales), legal and survey costs
• Improvements: planning permissions, builder and architect invoices, before-and-after photographs, anything that enhanced the property beyond its original state
• Disposal: the sale contract, estate-agent commission and legal costs

Capital records are not deducted against rental profit. They reduce the gain when you sell, so they must survive for the whole period of ownership and beyond. Residential gains are charged at 18% and 24% (FA 2024, with the annual exempt amount now £3,000), so a missing improvement receipt can cost real tax. The full detail of what to save and for how long sits in our guide to CGT record keeping for property sales, which feeds the main capital gains tax on property guide.

Section 24 records: why your finance costs need their own trail

Section 24 is fully in force. Finance costs on residential lettings (mortgage interest, arrangement fees, the interest element of certain other loans) are no longer deducted from rental profit. Instead they are relieved as a basic-rate (20%) tax-reduction credit applied after the tax on profit is calculated. That makes the finance-cost record a distinct line in your bookkeeping, not just another expense.

Keep the annual mortgage interest statement for every loan, plus any arrangement or broker fees, so the 20% credit can be evidenced and carried forward where it cannot all be used in a year. From 6 April 2027 property income is charged at its own separate rates of 22%, 42% and 47% under Finance Act 2026 (across England, Wales and Northern Ireland; Scotland is carved out for 2027/28), and the Section 24 reducer rises to 22% in step, so no new basic-rate wedge opens. Either way, the finance-cost evidence has to be there. For how the credit is computed and where it bites hardest, see our complete Section 24 guide.

Keeping records digitally

HMRC accepts digital records provided they are complete, accurate and accessible. For most landlords a digital-first approach is now the sensible default, and it becomes effectively mandatory once Making Tax Digital applies.

• Scan or photograph receipts and invoices on the day you receive them, then file by property and tax year
• Use a consistent file-naming convention so a document can be found in seconds during an enquiry
• Keep at least one backup, ideally in a second location or cloud service
• Check periodically that older files still open and have not become corrupted

Keep a small set of documents in original form regardless: property deeds and leases, original insurance schedules, and major capital-improvement invoices that may be challenged years later on sale.

Making Tax Digital and your records

Making Tax Digital for Income Tax changes how records are kept and reported, not how long they must survive. The mandation timetable, now in force, is staged by qualifying property and self-employment income:

• From 6 April 2026: qualifying income over £50,000
• From 6 April 2027: qualifying income over £30,000
• From 6 April 2028: qualifying income over £20,000

Once you are within MTD, records must be captured digitally, a digital link must run from source data through to the quarterly update, and you submit four quarterly updates plus a final declaration each year. The retention period is unchanged: the underlying evidence is still kept for the s.12B period. Choosing MTD software for landlords, and the digital-link mechanics, are covered in MTD record keeping for landlords and the April 2026 deadline guide.

Records for different property types

The core records are the same across portfolios, but several property types carry extra documents that HMRC and local authorities expect to see.

HMO landlords

• The HMO licence and any additional or selective licensing documents
• Individual tenancy agreements for each room
• Fire-safety, gas-safety and electrical (EICR) certificates
• Communal-area maintenance costs

Where a local authority has made an Article 4 direction (in named areas such as parts of Nottingham, Birmingham and several London boroughs), planning consent may be needed to create an HMO, so keep the planning correspondence too.

Holiday lets (after FHL abolition)

The Furnished Holiday Lettings regime was abolished from 6 April 2025, so holiday lets are now taxed as an ordinary property business with no special day-count tests. Keep:

• Booking-platform statements and occupancy records
• Cleaning and changeover costs
• Guest-damage and insurance claim records

Commercial property

• Business-tenant lease agreements and rent reviews
• Service-charge reconciliations
• Business-rates documentation
• VAT records, where the property has been opted to tax or you are otherwise registered

How to set up a record-keeping system this month

A system you can actually keep up with beats a perfect one you abandon by March. The routine below scales from one property to a portfolio, and it is the same property bookkeeping discipline whether you do it in a spreadsheet or in MTD software.

• Separate the money. Open a dedicated bank account for rental income and expenses. Nothing makes a return harder to defend than rental and personal money flowing through the same account.
• One folder per property. Digital or physical, with sub-folders for the tenancy, income, revenue expenses and capital expenditure. The revenue-versus-capital split lives here.
• Monthly: reconcile rent received against the bank statement, file the month's receipts, and note any arrears or repairs.
• Quarterly: review expense categories, update capital-expenditure records, and (once within MTD) prepare and submit the quarterly update.
• Annually: compile the figures for the Self Assessment return, archive the completed tax year, and review insurance and planned improvements.

Common record-keeping mistakes to avoid

• Missing receipts. Cash payments to a handyman with no receipt are routinely disallowed. Get a receipt, or pay through the bank account so there is a trail.
• Mixing personal and rental money. This is the most common trigger for assessments because HMRC cannot tell which receipt is rent.
• Collapsing revenue and capital. Claiming an improvement (an extension, a new kitchen that betters the property) as a repair overstates the deduction now and understates the base cost on sale.
• Vague descriptions. "Maintenance, £480" tells HMRC nothing. Record what it was and which property.
• No backup. A failed laptop the week before an enquiry is not a defence.

To illustrate, a landlord with two flats who reconstructed three years of records from memory after losing a phone faced an estimated assessment that was only reduced once bank statements were obtained from the bank and matched line by line, a slow and avoidable process. Good records would have closed the enquiry in a fortnight.

Penalties and what happens if your records are missing

If records are inadequate or cannot be produced, the exposure comes in layers.

• The records penalty (the floor). Section 12B(5) of the Taxes Management Act 1970 allows a penalty of up to £3,000 per year for failing to keep records. This rarely operates on its own.
• The tax-geared penalty (usually larger). Where missing records mean income was under-declared, HMRC charges a penalty on the lost tax: an inaccuracy penalty under Schedule 24 Finance Act 2007, or a failure-to-notify penalty under Schedule 41 Finance Act 2008 if a letting source was never declared.
• The assessment window. HMRC's reach is not a flat 20 years. The ordinary limit is 4 years (TMA 1970 s.34). It extends to 6 years for carelessness (s.36(1)), 20 years for deliberate behaviour (s.36(1A)), and 12 years for innocent offshore errors (s.36A).

The penalty bands, how behaviour is graded, and the voluntary-disclosure routes available if you already have gaps (the Let Property Campaign and the Worldwide and Digital Disclosure facilities) are set out in our companion guide on record retention, voluntary disclosure and failure to notify. If you suspect a gap, disclosing it before HMRC opens an enquiry materially reduces the penalty.

When to bring in a property accountant

Robust records are something most landlords can run themselves. The point at which professional support earns its place is usually one of the following:

• You own multiple properties and the per-property reconciliation, the heart of property portfolio accounting, is slipping
• You are considering incorporating into a limited company, which changes the retention rules to the 6-year company basis
• You have complex financing or a portfolio spread across structures
• You are onboarding to Making Tax Digital and need the records to be MTD-ready
• You are facing an HMRC enquiry and need missing records reconstructed and presented properly

A specialist property accountant can set up the system, separate revenue from capital correctly, and make sure every allowable expense is captured while the records stay compliant. If any of the triggers above apply, the form below routes to a specialist who handles property landlords.
