Believe me there are ways and means of doing things like that, As a company director, you learn these things very quickly, Specially if your a limited company, If your on a zero houred contract I take it your classed as self employed? so things like rent of your "business" premise which just happens to be were you sleep is all tax deductable, Mileage for his business is all charged at 45p a mile, electric, gas etc is all on "the company" so, you might have a bit corperation tax to pay, the last thing our pilot wants to do in his first 2 years is make any sort of profit! and when he's found his job with a full contract, wind his company up!
All true.
Know someone who works as a senior exec in manufacturing business, does Interim work and he told me that he earned in excess of £200 k last year and paid £5k tax........all via Ltd company.
Now people will complain about what he pays and probably rightly so. But when he a full time exec in business 3-4 years ago he said was paying £100k in tax.
