Erik - are you brain dead too?

"Mistakes" are not cheating.

"Avoidable mistakes" is a description that is a passport to persecution.

Pregnant female teenagers are unlikely to be accommodated by their parents - if they got on well with them they wouldn't be where and who they are. You've been reading the Daily Mail again, and you've not been reading the housing statistics.

And targetting those vulnerable people, where it will harm them, will reap nothing like the benefits of the equivalent effort on collecting all tax due. A few simple legal principles would fix the tax planning black hole: -

1. Transactions will be taxed as if they had been done the simplest way and all money moving had done so in the UK. That will end about 90% of tax schemes.
2. Legal advisers and accountants advising on tax schemes that fail to be jointly and severally liable for the tax clawed back and pursued through foreign courts if necessary.
3. Tax advisers trained by the Inland Revenue who leave and earn more than double their HMCS final salary to repay the HMCS assessment of their training costs (like student loans, really - but there should be no cap - the more they earn as "tax advisers" the more they pay back into the public purse on top of income tax).
