What is a Self Assessment?

Self Assessment more correctly known as the Self Assessment Tax Return, is a form that provides details of your income for HMRC. If you are self employed you need to submit a Self Assessment Tax Return to HMRC every year.

Most business owners and all self-employed people file Self Assessment Tax Returns with HMRC. It is called ‘Self Assessment’ because you fill in the details of your income yourself to work out how much tax you need to pay HMRC; other terms for Self Assessment include Income Tax Return or Personal Tax Return.
