There are two tax credits – child tax credit and working tax credit. You can claim one or both of them, depending on your household circumstances.
Working tax credit is paid to people who work and are on a low income – it does not matter whether you are an employee or self-employed, and you do not need to have children. Child tax credit is paid to people who have children. It is paid in addition to child benefit and you do not have to be working to get it.
Tax credits are administered by HM Revenue & Customs.
