The HMRC Tax calculator app allows people to work out how much tax they pay and how the Government spends it. The app was introduced in Spring 2012 and is periodically updated with new features.
The HMRC Tax Calculator can be downloaded for free from Apple's App store or from Google Play. It is also available online (as a browser version).
To help small businesses with record keeping on the go, the commercial software industry, following consultation with HM Revenue & Customs (HMRC), are producing simple record keeping mobile applications for businesses below the VAT threshold.
