Business records if you’re self-employed
You must keep your records for at least 5 years after the 31 January submission deadline of the relevant tax year. HM Revenue and Customs (HMRC) may check your records to make sure you’re paying the right amount of tax.
Example – If you sent your 2019 to 2020 tax return online by 31 January 2021, you must keep your records until at least the end of January 2026.
Very late returns
If you send your tax return more than 4 years after the deadline, you’ll need to keep your records for 15 months after you send your tax return.
Business records if you’re a Limited companies
Limited companies are required to hold a wide range of company and accounting records. This includes details of directors, shareholders, company secretaries and the results of any shareholder votes and resolutions.
The company must also keep a register of People with Significant Control (PSC register).

- all money received and spent by the company, including grants and payments from coronavirus support schemes
- details of assets owned by the company
- debts the company owes or is owed
- stock the company owns at the end of the financial year

- all goods bought and sold
- who you bought and sold them to and from (unless you run a retail business)
The records must be held for 6 years from the end of the last company financial year they relate to, or longer if:
- they show a transaction that covers more than one of the company’s accounting periods
- the company has bought something that it expects to last more than 6 years, like equipment or machinery
- you sent your Company Tax Return late
- HMRC has started a compliance check into your Company Tax Return.
