Self Assessment Tax Return
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 a tax return.
Who must send a tax return
You must send a tax return if, in the last tax year (6 April to 5 April), you were:
Self-Employed as a ‘Sole Trader’ and earned more than £1,000
A partner in a business partnership
You will not usually need to send a return if your only income is from your wages or pension. But you may need to send one if you have any other untaxed income, such as:
money from renting out a property
tips and commission
income from savings, investments and dividends
foreign income
Claim income tax relief such as pension contributions, charity donations
