Landlord Record Keeping: What You Need to Track and Why

Good records protect you from HMRC penalties, compliance fines, and tenant disputes. Poor records cost you money — in missed deductions, failed audits, lost deposit disputes, and £1,000+ HMRC penalties for missing record-keeping requirements. With Making Tax Digital for Income Tax (MTD ITSA) launching for the first cohort of landlords from April 2026, the legal requirement to keep digital records is no longer aspirational — it's enforced. This guide walks the full record-keeping checklist by category, the retention rules HMRC + the deposit schemes + Right to Rent require, and the practical day-to-day workflow that keeps it sustainable across a multi-property portfolio.

Why record-keeping matters more in 2026 than 2024

• MTD ITSA — from April 2026 (combined gross income above £50,000), April 2027 (£30k), and April 2028 (£20k), digital records are legally required and must support quarterly HMRC submissions. Pre-MTD landlords could survive on a shoebox of receipts; post-MTD that's non-compliant and the penalty regime is distinct from regular SA late-filing penalties.
• Renters' Rights Act — Section 21 abolition means more disputes now go through Section 8 with grounds-based evidence. Strong records are the difference between a successful possession order and a wasted three-month court process.
• Stricter MEES enforcement — minimum EPC penalty rising from £5,000 to £30,000 per property. PRS Exemptions Register evidence requires documented quotes + technical assessments; landlords without paper trail can't claim exemptions.
• HMRC's "nudge" letters — HMRC routinely cross-references Land Registry, Council Tax, and Letting Agent CLM data to identify undeclared rental income. A nudge letter triggers a discovery enquiry; sloppy records become a four-figure problem fast.

Financial records

Income

• Rent received — amount, date, tenant, and property
• Date the rent was DUE versus the date it was RECEIVED (matters for arrears tracking)
• Other income — fees, key replacement charges, parking charges, end-of-tenancy charges retained
• Insurance pay-outs (loss of rent, building damage)
• Bank statements showing all rental income transactions (HMRC can ask)
• Refunds you've issued (deposit returns, overpayment refunds — these reduce taxable income)

Expenses (allowable revenue)

• Mortgage interest statements (for Section 24 tax credit)
• Repair and maintenance receipts
• Insurance premiums (buildings, contents, liability, rent guarantee)
• Letting agent fees + management fees
• Accountancy + tax preparation fees
• Travel costs for property management (mileage log + train tickets)
• Utility bills (if you pay them — typically HMOs or vacant periods)
• Council tax during void periods
• Service charges (leasehold properties)
• Ground rent
• Replacement of Domestic Items (white goods, carpets, curtains, sofas — like-for-like)
• Marketing + advertising costs
• Tenant referencing fees
• Right to Rent check costs
• Cleaning between tenancies
• Garden maintenance
• Communications costs (mobile + broadband attributable to landlord work)
• Subscription costs for landlord software (Tendmere itself is allowable)

Capital expenditure (separate ledger)

• Purchase price + SDLT + legal fees + survey fees on acquisition
• Improvements (extensions, conversions, kitchen replacements that go beyond like-for-like)
• EPC upgrade costs (insulation, heating system replacements)
• Selling costs (estate agent + legal fees) when you eventually sell

Capital expenditure isn't deducted from rental income — it reduces your CGT base when you sell. Keep these records as long as you own the property AND for 6 years after sale.

Receipts — the format HMRC actually accepts

Each receipt needs to show:

• Vendor name + address
• Date
• Itemised description of goods / services
• Amount + VAT (if applicable)
• VAT registration number (if VAT-charging vendor)

HMRC may accept digital copies when they preserve the required record. Tendmere lets you attach the receipt and review its amount, date, vendor and SA105-aligned category; you or your accountant remain responsible for the record and tax treatment.

Compliance records

• Gas Safety Certificates (CP12) — current plus all historic copies for the property's let history
• EPC certificates — valid for 10 years; keep all historic versions in case of MEES enforcement
• EICR reports — valid for 5 years
• Deposit protection certificates — with prescribed information served to tenant
• Prescribed information receipt — proof the tenant received the deposit info within 30 days
• Right to Rent check records — keep for 1 year after tenancy ends; civil penalty up to £20k per illegal occupant if missing
• How to Rent guide — proof you served the latest version to the tenant before move-in (England only)
• Smoke and CO alarm test records — at start of every tenancy from October 2022
• Selective licensing certificates — where the property is in a designated area
• HMO licences + room schedules for HMOs
• Legionella risk assessments — required for all rentals; refresh every 2 years
• PAT testing records for furnished lets (recommended, not legally mandated for ASTs)
• Inventory + check-in / mid-tenancy / check-out inspection records with photos
• Insurance policy schedules showing dates of cover

Tenancy records

• Tenancy agreements (signed by all parties, dated)
• Tenant ID copies + Right to Rent check evidence
• Tenant referencing reports
• Inventory + check-in / mid-tenancy / check-out reports with photos
• Correspondence with tenants (especially about repairs, complaints, notices)
• Maintenance request log + completion records
• Section 8 / Section 13 notices, and any historic Section 21 notices, if served — including proof of service
• Any payment plans agreed with tenants for arrears
• Prior-landlord references provided to incoming tenants of yours

HMO + multi-let records

HMOs need additional records because of the licensing regime:

• HMO licence + conditions
• Manager nominated person details
• Room schedules + occupancy
• Common-area cleaning records
• Fire risk assessment
• Emergency lighting test records
• Fire-door inspection records
• Annual portable appliance test results
• Communal-area gas safety + electrical certificates

How long to keep records (HMRC + statutory + practical)

• Tax records (general): 5 years after the 31 January submission deadline for the relevant tax year (effectively 6 tax years total). MTD ITSA tightens to "for as long as required to support digital submissions" but 6 years is the safe floor.
• Tax records under HMRC enquiry: Until enquiry closes, even if past the 6-year window.
• Capital records (purchase + improvements): For as long as you own the property + 6 years after sale.
• Right to Rent: 1 year after tenancy ends.
• Deposit protection prescribed information: Until deposit fully returned and disputed amounts adjudicated.
• Tenancy agreements: 6 years after tenancy ends (limitation period for contract disputes; 12 years if executed as a deed).
• Gas safety certificates: 2 years minimum per the Gas Safety Regs; sensible practice is "all historic copies for the property" so MEES + dispute claims are fully evidenced.
• EPC + EICR: All historic copies — useful for MEES exemption claims years later.
• HMRC nudge / enquiry letters: Permanently. They occasionally re-open old enquiries.
• Section 8 notices and historic Section 21 notices: Permanently. A future tenant or landlord-body audit may want to see your enforcement history.

Digital vs paper

HMRC has accepted digital records since 2017. From April 2026 (MTD ITSA cohort 1), digital records are MANDATORY for landlords with combined SE + property income above £50,000. Threshold drops to £30k from April 2027 and £20k from April 2028.

Even below threshold, digital records are safer:

• Can't get lost in a drawer or damaged by a leak
• Searchable in seconds (try finding a 2021 boiler service receipt in a paper file)
• Backed up automatically (cloud storage with EU data residency)
• Shareable with your accountant in real time
• Time-stamped, EXIF-preserved photos hold up better in tribunal hearings than dated handwritten notes

Compliance approach: scan paper receipts the day they arrive (phone OCR is fine), file by category + tax year, dispose of the paper after 12 months once you're sure the digital copy is backed up.

The realistic monthly record-keeping rhythm

• Daily: Review manually recorded or imported rent and expense transactions. Tendmere's automatic Open Banking feed is not live.
• Weekly: Photo-scan any paper receipts. Snap a photo on your phone; the OCR pulls vendor + amount + date.
• Monthly: Reconcile incoming rent against expected. Investigate any gaps (missing payments, late payers).
• Quarterly: Review the cumulative MTD figures and use approved filing software for the HMRC update. Tendmere's production HMRC submission remains disabled until approval and production verification are complete.
• Annually: Review compliance certificate calendar for the next 12 months. Book Gas Safety, EICR, EPC renewals before they expire. Renew your insurance.
• At year-end: Run the annual report, share with your accountant, file the SA return.

Common record-keeping failures

• Mixing personal + landlord finances on the same bank account. Makes reconciliation a nightmare and obscures expense claims.
• Not recording mileage at the time. HMRC won't accept estimates; keep a contemporaneous log.
• Lost receipts for cash payments. Cash to a contractor with no receipt = no allowable expense. Get the receipt or pay by transfer.
• Tenancy agreements never signed digitally + the original lost. Counter-sign electronically using a tool that creates an audit trail.
• Right to Rent checks done but not retained. The check itself doesn't matter without the documentary evidence; civil penalty applies regardless of whether you actually checked.
• Deposit protected but prescribed-information receipt not retained. Tenant can claim 1× to 3× deposit penalty; you need the proof of service to defend.
• EPC expired between tenancies and no record of which tenancy began when. MEES penalty applies to letting; you need to be able to show the EPC was valid at the time.

How Tendmere helps

Tendmere organises the income, expenses, compliance dates and documents you record. Review extracted or entered fields against the source, link them to the property timeline, and use search, exports and audit history for handoff. The existence of a stored file or audit row is not legal or tax certification.
