Question: is working tax credit classed as a benefit

Answer: Yes, Working Tax Credit (WTC) is a state benefit in the United Kingdom made to people who work and have a low income. It was introduced in April 2003 and is a means-tested benefit. Despite their name, tax credits are not to be confused with tax credits linked to a person's tax bill, because they are used to top-up wages. Unlike most other benefits, it is paid by HM Revenue and Customs (HMRC).
