Tax: keeping records

What records to keep

The records you need to keep will, broadly speaking, be the documents you have used to complete your return. This might include:

• details of self-employment income and expenses to work out your trading profit or loss for the year
• details of property income and expenses to work out your rental profit or loss for the year
• employment and pensions income information, including forms P60, P11D and P45 from any jobs you have had
• interest certificates from banks or building societies
• details of pension contributions – in particular, those made to relief at source schemes 
• details of any chargeable capital gains made in the year
• records to support your residence status
• for tax years starting from 2025/26, if you claim relief under the foreign income and gains regime, records of your foreign income and gains, including amounts not taxed in the UK
• for tax years up to and including 2024/25, records to support your domicile status and, if you claimed the remittance basis of taxation, records to support what you have (or have not) remitted to the UK*

*The concepts of ‘domicile’ and ‘remittance basis’ are only relevant up until the 2024/25 tax year. The foreign income and gains regime applies for tax years starting from 2025/26. You can read about these rules in our International Section.

Self-employed and landlords

For self-employed and property income, you need to be able to show how you have worked out your profit. So, you need to keep things like:

• invoices (bills) for work you have done
• receipts for expenses paid
• bank statements
• statements from letting agents (or details of rental income for property if you do not use an agent)
• information showing how you have taken account of any private use of things used in the business (for example, mileage logs for a vehicle used both in the business and privately).

You can keep Self Assessment records on paper or digitally. However, if you are required to follow the Making Tax Digital for income tax rules which are introduced from April 2026, you will be required to keep digital records of your self-employment and/or property income and expenses. 

For more information on record-keeping when self-employed see our page Business record-keeping.

How long to keep records for

How long you need to keep records depends upon what types of income and gains you have. 

Self-employed and landlords

The normal rule for the self-employed and those letting property is to keep business records for at least five years from the 31 January submission deadline. For example, records for the 2025/26 tax return should be kept until 31 January 2032.

In self assessment but not self-employed

If you submit your tax return on time, you should keep your records for at least 22 months after the end of the tax year. For example, you should keep records for your 2025/26 tax return until at least 31 January 2028.

If you submit your tax return late or make an amendment to a tax return, you should keep your records for at least 15 months after you sent your tax return.

If HMRC ask you for your records

You do not have to send original documents to HMRC with your tax return, but if HMRC decide they want to check your tax return and so open an enquiry or a compliance check later, you might need them as back-up and to show you took reasonable care to get your tax return right. HMRC may ask to see some of your records when they check your return. 

HMRC can charge you a penalty if your records are not complete and accurate.
