Obviously we now all know what everyone suspected anyway but would you 'exploit' the rules if you could? Sadly I'll never get beyond the realms of PAYE so such options aren't open but I'm not sure if I actually would given I live fairly comfortably on a below average wage and even a couple of hundred quid more a month would let me buy whatever I wanted. If was on 6 figures onwards, other than expensive cars and cycling holidays, I don't know what I'd waste it on.
I suppose you could give some away to charity from what you'd dodged but you're probably doing the nation more good just paying tax. It's all very well people like Hamilton doing charity work but not paying £3m VAT which could have bought a lot of school book, etc.
I've a couple of self-employed mates who do all sorts of dodges. One races motorbikes as a hobby and manages to pull some scam off that involves sponsoring himself to write something off.
