Question: is tax evasion a crime in the uk

Answer: Yes, HMRC, the UK tax collection agency, estimated that in the tax year 2016--17, pure tax evasion (i.e. not including things like hidden economy or criminal activity) cost the government £5.3 billion. This compared to a wider tax gap (the difference between the amount of tax that should, in theory, be collected by HMRC, against what is actually collected) of £33 billion in the same year, an amount that represented 5.7% of liabilities. At the same time, tax avoidance was estimated at £1.7 billion (this does not include international tax arrangements that cannot be challenged under the UK law, including some forms of base erosion and profit shifting (BEPS)).
