Landlord Tax Records: What to Keep and for How Long

Landlords should keep complete records of rental income, expenses, ownership, finance and property transactions. Self Assessment records normally need to be retained for at least five years after the 31 January filing deadline, with longer retention where a return is late, HMRC opens an enquiry or documents support a later property sale.

Rental income records

• tenancy and licence agreements;
• rent schedules and tenant ledgers;
• letting-agent statements;
• bank, card and payment-platform statements;
• deposit protection and deductions;
• insurance receipts and compensation;
• income from parking, services or other property rights.

Reconcile gross rent before agent fees. If an agent receives £1,000 and keeps £120, income is generally £1,000 and the £120 is considered separately as an expense.

Expense evidence

• repair and maintenance invoices;
• agent, accountant and legal fees;
• insurance, service charges and ground rent;
• Council Tax and utility bills paid by the landlord;
• travel logs and mileage evidence;
• replacement domestic-item invoices;
• advertising, safety certificates and licensing costs.

Record the business purpose, property and payment date. A bank line proves payment but may not prove what was purchased or whether it was a repair.

Mortgage and finance records

• loan agreements and completion statements;
• annual mortgage-interest certificates;
• arrangement, valuation and redemption fees;
• bank evidence tracing the use of borrowed funds;
• refinancing calculations and property valuations;
• carried-forward residential finance-cost schedules.

Separate interest and fees from mortgage capital repayments. Individual residential landlords normally claim a basic-rate finance-cost reduction rather than a full expense deduction.

Capital expenditure and CGT records

Keep purchase and sale completion statements, Stamp Duty Land Tax evidence, legal and estate-agent fees, surveys and invoices for capital improvements. These may be required decades later to calculate Capital Gains Tax.

Describe improvements and retain before-and-after evidence. Routine repairs are generally rental expenses, while enhancements such as an extension may form part of CGT base cost. A cost cannot be claimed twice.

Ownership records

• Land Registry title and purchase documents;
• declarations of trust and beneficial-ownership agreements;
• Form 17 and supporting evidence where relevant;
• partnership agreements;
• records of spouse or civil-partner transfers;
• probate valuations for inherited property.

The bank account receiving rent does not by itself determine who is taxable.

Private Residence Relief evidence

If a rental property was once your main home, retain dates and evidence of occupation: Council Tax, electoral registration, utility bills, correspondence and details of other homes. Keep letting dates and shared-occupation evidence for any potential Letting Relief claim.

Cash basis records

Most individual landlords with property receipts up to £150,000 use cash basis by default. Record when money is received and paid. If accrual accounting is elected, maintain debtors, creditors, accruals and prepayments.

Property allowance and Rent a Room

Retain gross receipts and the calculation comparing actual expenses with the chosen allowance. The £1,000 property allowance cannot be combined with actual expenses for the same income. Rent a Room has separate limits and conditions.

Joint property

Each owner should retain the full-property records and their allocation. Married couples and civil partners living together generally report 50:50 unless a different beneficial split and valid declaration apply. Track each owner’s losses and finance-cost carry-forwards.

Foreign property

Keep overseas statements, tax returns, tax-payment evidence, ownership documents and exchange-rate calculations. Foreign tax credit relief needs proof of foreign tax paid. Records may need translation.

Making Tax Digital records

MTD for Income Tax starts from April 2026 above £50,000 qualifying income, April 2027 above £30,000 and April 2028 above £20,000. In-scope landlords must keep required income and expense data digitally in compatible software. Source documents should remain accessible and linked where practical.

How long to retain records

Digital storage checklist

1. Scan receipts before they fade.
2. Use one folder or ledger code per property.
3. Back up records in more than one secure location.
4. Export data before changing agents or software.
5. Use multifactor authentication and controlled access.
6. Document corrections and preserve the audit trail.
