Customers who voluntarily come forward and put right their tax position can expect very similar terms to those on offer through PTSP. If you do not come forward and HMRC later find that you owe additional tax, you may face higher penalties or even criminal investigation.
Anybody with extra income or gains to disclose, whether in the plumbing industry or not, should seriously consider coming forward now. Those who do not and who are subsequently found out will be liable to penalties of between 35% and 100% of the tax evaded. And may well be subject to increased scrutiny for the next five years. The rules are changing. Tax cheats - whether local tradespeople, property owners, entrepreneurs or anyone else are all in the same boat. Make sure yours has a paddle - or even a motor!
