Self-Assessment is a system HM Revenue and Customs (HMRC) uses to collect Income Tax.

Tax is usually deducted automatically from wages, pensions and savings. People and businesses with other income must report it in an annual tax return.

You will also know that the penalties for failing to submit your return on time, or incorrectly, can give rise to substantial fines.
