Records You Must Keep If You’re Self-Employed
This guidance is for self-employed individuals and sole traders who need to understand what business records must be kept to meet HMRC requirements.
This page explains the types of records you must keep when self-employed, how long they should be retained, and why proper record-keeping is essential for accurate tax reporting.
HMRC expects self-employed taxpayers to keep clear and complete records. Poor or missing records can lead to incorrect tax returns, difficulties during an HMRC enquiry, and potential penalties.
What records must be kept when self-employed
If you are self-employed, you are required to keep records that fully support the figures included in your Self-Assessment tax return. These records should clearly show your business income and expenses.
Income records
You must keep records of all income received by your business, including:
- Sales invoices and receipts
- Cash takings records
- Bank statements showing business income
Expense records
Records should be kept for all allowable business expenses, such as:
- Receipts for purchases and running costs
- Travel and mileage records
- Use of home for business calculations
- Professional fees and subscriptions
Expenses must be supported by evidence and be wholly and exclusively for business purposes.
Asset records
If you buy or sell business assets, you should retain records relating to:
- Equipment, tools, or machinery
- Vehicles used for business purposes
- Dates of purchase and disposal
- Amounts paid or received
These records may be required to support capital allowance or disposal calculations.
How long must self-employed records be kept?
HMRC generally requires self-employed individuals to keep records for at least 5 years after the 31 January submission deadline for the relevant tax year.
For example, records for the 2023–24 tax year should normally be kept until at least 31 January 2030.
Risks and consequences of poor record-keeping
Failure to keep adequate records can lead to:
- Incorrect Self-Assessment returns
- HMRC enquiries or compliance checks
- Penalties or interest if errors are found
- Difficulty defending income or expense figures
HMRC may estimate your tax position if records are missing or unreliable, which often results in higher assessments.
In practice: what we commonly see
In practice, we often see HMRC challenge expense claims where receipts are incomplete or inconsistent. Digital records are accepted, but they must still be clear, accurate, and retrievable. Problems frequently arise where personal and business finances are mixed or where records are reconstructed long after the event.

Frequently Asked Questions
What records must a self-employed person keep for HMRC?
Self employed record keeping requirements cover three core categories. Income records must include all sales invoices, receipts, cash takings, and bank statements showing business income. Expense records must cover receipts for all allowable business costs from travel and materials to professional fees and home working calculations. Asset records must document any equipment, machinery, or vehicles used for business, including purchase dates, amounts paid, and disposal details for capital allowance purposes.
How long must self-employed individuals keep their business records?
HMRC requires self-employed individuals to keep business records for at least five years after the 31 January submission deadline for the relevant tax year. For example, records for the 2023–24 tax year must normally be retained until at least 31 January 2030. This retention period applies to all income, expense, and asset records used to support figures declared in your Self Assessment tax return.
How do you keep accounts as a self-employed person?
To keep accounts as a self-employed person, record all business income and expenses consistently throughout the year do not leave it until just before your Self Assessment deadline. Separate your business and personal finances by using a dedicated business bank account. Keep all invoices, receipts, and bank statements organised by tax year. Digital records are accepted by HMRC and are strongly recommended, as they are easier to retrieve and less likely to be lost or damaged than paper records.
What expense records does HMRC require for self-employed individuals?
HMRC requires self-employed individuals to keep supporting evidence for every allowable business expense claimed. This includes receipts for purchases and running costs, travel and mileage logs, records supporting any home office cost calculations, and invoices for professional fees and subscriptions. Expenses must be wholly and exclusively for business purposes HMRC may disallow claims where adequate supporting records are not available, which can result in a higher tax liability.
What happens if a self-employed person has poor or missing records?
Poor or missing records in self employment accounts can trigger HMRC compliance checks, lead to incorrect Self Assessment returns, and result in penalties or interest if errors are identified. Where records are insufficient, HMRC may estimate your income and tax position — typically resulting in a higher assessment than your actual liability. HMRC commonly challenges expense claims where receipts are incomplete or inconsistent, particularly where personal and business finances have not been kept separate.
Are digital records acceptable for self-employed HMRC compliance?
Yes. HMRC accepts digital records for self employed record keeping purposes, provided they are clear, accurate, and retrievable. Digital records can include scanned receipts, electronic invoices, bank statements downloaded from online banking, and records maintained in accounting software or spreadsheets. Under Making Tax Digital for Income Tax mandatory for eligible self-employed individuals from April 2026 digital record keeping will become a legal requirement rather than simply an accepted alternative to paper records.
Do self-employed people need to keep asset records as well as income and expense records?
Yes. Self employed record keeping obligations extend beyond income and expenses to include records of any business assets equipment, tools, machinery, or vehicles used for business purposes. These records must show purchase dates, amounts paid, and disposal proceeds. Asset records are essential for calculating capital allowances and any chargeable disposals, and HMRC may request them during a compliance check if capital allowance claims appear in your Self Assessment tax return.
