Self Employment Business Records

Information in this section explains how to do accounts for self employed workers. Check your responsibilities for keeping business records if you are self-employed.

BASIC ACCOUNTING: You must keep business records and paperwork if you are self-employed.

There are extra responsibilities for the nominated partner in a partnership. As such, the nominee must also keep certain records about the business partnership.

Note: This section explains the rules of accounts and keeping records for self employed. They are different to limited company accounting records.

Accounting Method for Self Employed

As a worker in self-employed status you will need to choose to run one of the accepted accounting methods. You can choose between traditional accounting and the cash basis system.

Traditional Accounting Methods

The accrual basis of accounting method is very popular with many businesses. The date you write invoices or get billed determines when you record the income and expenses.

An Example: You write an invoice for a customer on the 19th of March 2018. You would record that invoice for the 2017 to 2018 tax year. This would still apply even if the business did not receive the money until the next tax year [2018/19].

Cash Basis Accounting System

Many small businesses use cash basis accounting procedures. The system has many advantages for businesses with an annual turnover up to £150,000.

The cash basis method of reporting is different to traditional accounting. With cash basis you would only record income or expenses at the time you actually receive money or you pay a bill. The advantage is not having to pay Income Tax on money not yet received in that accounting period.

An Example: You wrote an invoice on the 19 of March 2018 for a customer. But, the business did not receive the money until the 19th of April 2018. Thus, you would record this income in the 2018 to 2019 tax year.

Most accountants suggest keeping your paperwork for at least six (6) years. But, HMRC say you must keep your records for at least five (5) years from the 31st of January submission deadline of the relevant tax year.

HM Revenue and Customs may carry out a tax compliance check of your self employment business records. This is to ensure you pay the correct amount of taxation. But, there is no limit for cases of fraud or willful default.

An Example: You send your 2016 to 2017 tax return online before the Self Assessment deadline of the 31st of January 2018. In this case, you must keep the records until at least the end of January 2023.

Sending Very Late Tax Returns

Different rules apply if you send a tax return more than four (4) years after the deadline. In this case, you would need to keep all the records for at least 15 months after you send in a tax return.
