What ‘stealth tax grabs’ are you referring to biglouis?
People working for cash and not declaring their income are guilty of tax evasion. If I knew of someone doing that I wouldn’t hesitate to report them to HMRC.
I read it that biglouis was referring to the frozen personal allowances. I think the description of it as a 'stealth tax grab' is apt. I suspect that many people won't be aware that freezing the PA means that they will be paying more tax.
The Black economy is, of course, a completely different issue
