The site – www.gov.uk/sortmytax – has been established using part of the £917m allocated from government to tackle tax avoidance.
David Gauke, exchequer secretary to the Treasury, said: “It always makes sense to declare all your income and tax dodgers are simply storing up trouble for the future; getting caught means higher fines, and in the most serious cases criminal prosecution.
“There is an alternative. Simply visit the new website and make a fresh start.”
HMRC director-general, enforcement and compliance Jennie Granger added: “Most people pay the right tax. Our campaign is aimed at those who don’t. Our message to the small percentage who don’t is a simple one: ‘The net is closing in.'”
”If you’ve declared all your income you’ve nothing to fear. And if you know someone who isn’t paying what they should, get in touch with HMRC. It isn’t fair that you pay what you should and they don’t.“
The campaign is one part of HMRC’s broader work to tackle evasion and fraud which includes taskforces, campaigns and offshore penalties.
HMRC aims to raise an additional £7bn a year by 2014/15 by tackling tax evasion.
