Record Keeping for Tax

When you submit a Self Assessment tax return, you do not need to send your receipts or physical documents directly to HMRC. However, you are legally required to store them securely. HMRC routinely conducts formal compliance checks and tax enquiries, and failing to produce original evidence of your income or expenses can result in penalties of up to £3,000 for negligent record-keeping.

The exact length of time you must keep your paperwork depends entirely on the source of your income.

The Two Timelines for the 2026/27 Tax Year

Your statutory record-retention window follows one of two distinct pathways based on how you make your money.

Route 1: Self-Employed and Landlords (Business Filers)

If you file a return containing self-employed trading profits or property rental income, you must preserve your business documentation for at least 5 years after the 31 January submission deadline of the relevant tax year.

• 2026/27 Example: For the tax year ending 5 April 2027 (which carries a standard online filing deadline of 31 January 2028), you must safely store your business invoices, receipts, and bank statements until at least 31 January 2033.

Route 2: PAYE Employees and Investors (Non-Business Filers)

If your tax return is limited to reporting personal investments, capital gains, high-income charges, or employment benefits, your timeline is shorter. You only need to retain your personal records for 22 months after the end of the tax year.

• 2026/27 Example: For the tax year ending 5 April 2027, you only need to keep your personal tax documents until at least 31 January 2029 (roughly one year after the filing deadline).

The Late Filing Exception

If you submit your Self Assessment tax return late, the standard 5-year or 22-month deadlines are completely overridden. Under these circumstances, you must legally retain your records for a minimum of 15 months from the exact calendar date you physically submitted the return to HMRC.

What Records Do I Need to Keep?

You must preserve any original documentation used to calculate the figures entered on your return. This includes, but is not limited to:

• Business and Property: Sales invoices, cash receipts, bank statements, tenant rent logs, and mileage tracking records.
• Employment: P60 year-end statements, P45 forms from past jobs, and P11D benefits-in-kind summaries.
• Investments and Assets: Dividend vouchers, annual bank interest certificates, stock broker statements, and cryptocurrency transaction histories.

The Making Tax Digital (MTD) Mandate

For the 2026/27 tax year, record-keeping has shifted to digital formats for higher earners. If your gross qualifying income from your self-employed trade or property portfolio exceeds £50,000, paper-only tracking is no longer legally compliant.

Under the active Making Tax Digital (MTD) rules, you are legally mandated to preserve your business records digitally and use MTD-compatible software to submit your quarterly financial updates to HMRC.

Key Points to Remember

• Business filers must keep all records for 5 years after the January filing deadline.
• Non-business filers must keep records for 22 months after the tax year ends.
• Late returns trigger a rolling requirement to keep files for 15 months from submission.
• Taxpayers with gross trading or property income above £50,000 must keep all business records digitally under active MTD rules.
