HMRC Record-Keeping for Self-Employed Tutors: What You're Legally Required to Keep

If you're a private tutor working for yourself, HMRC expects you to keep proper records — not just for your annual tax return, but in case they ever open an enquiry. This guide covers exactly what records you're legally required to hold, how long to keep them, and what HMRC will look for if they investigate.

Why Record-Keeping Matters

As a self-employed tutor, you file a Self Assessment tax return each year. The income and expenses you declare must be backed up by records. If HMRC opens a compliance check — and they do, sometimes years after the relevant tax year — you'll need to produce those records on request.

If you can't, HMRC has the power to estimate your income and raise a tax bill. Penalties and interest can be added on top. The safest position is clean, consistent records that tell the same story as your bank statements.

What Records You're Required to Keep

HMRC requires self-employed individuals to retain records of:

Income Every payment you receive from every student or family — bank transfers, standing orders, and cash. Cash payments are especially important: HMRC cannot see these in your bank statements, so if your records don't reflect them, any discrepancy can be treated as undeclared income. Keep a simple payment log for every session, even if you're paid informally.

Expenses Receipts and records for every cost you claim against your tax bill. Allowable expenses for tutors typically include lesson materials and resources, professional subscriptions (tutor associations, DBS renewal), equipment used exclusively for tutoring, and travel to students' homes (with a mileage log if you drive).

If you teach from home, you may also be able to claim a proportion of household running costs — but this needs to be calculated correctly and documented.

Invoices If you issue invoices to students or families, keep a copy of every one sent. If you don't formally invoice but receive regular bank transfers, your bank statements serve as the record — label each one clearly so you can identify who paid and for what.

Bank statements Keep all statements for accounts that receive tutoring income or pay tutoring expenses. These are the most important cross-reference HMRC will use.

How Long to Keep Your Records

The legal minimum is five years after the 31 January submission deadline for the relevant tax year. In practice, plan for around six years from the end of the tax year in question.

For example: records for the 2024/25 tax year (which ended 5 April 2025) must be kept until at least 31 January 2031.

If HMRC opens an enquiry before that deadline, you must keep everything until the enquiry is formally closed — regardless of how long that takes.

What HMRC Looks For

During a Self Assessment enquiry, HMRC will typically request:

• A complete record of all income received, including cash and informal payments
• Evidence that claimed expenses are "wholly and exclusively" for tutoring purposes
• A mileage log if travel costs have been claimed
• Confirmation that your declared figures reconcile with your bank statements
• Records of any other income sources that could affect your overall liability

The most common issues HMRC identifies in self-employed tutor cases: unrecorded cash payments, overclaimed home-office costs, and travel claims with no supporting log.

Keep It Simple — But Keep It Consistently

You don't need specialist software. A spreadsheet that logs every payment in and every business expense out — kept up to date throughout the year — covers the basics for most sole-trader tutors. Add a folder of digital receipt scans and you're well ahead of the average compliance check.

The key is doing it regularly. Records written at the end of the year from memory are far less convincing to HMRC than records that match the date and amount of every transaction as it happened.
