What part is not understood here?
If you breach the spirit of the law, then you’re just a crook by alternative means. A kind of cold war against the tax payer because you expect some other bod to pay the taxes that you and your firm have successfully evaded.
And to think that there are plenty on here who think I’M some sponger scumbag playing a bent system because I do it all by the book, providing receipts, etc…
I’ve turned down 75+ hour weeks when offered because it’s bent. Screw the big payday, I’m not interested in breaching even the spirit of the law here that is to stop half-asleep drivers running up someone else’s arse at 3am because they’re 65 hours into an 84 hour week!
Everyone’s non-receiptable tax allowance is around £8kpa which means the first £160 a week is tax free for most of us on the road. It makes more sense therefore to exceed this only by the amount required to be totally offset in legitimate (receipted) expenses, and keep to that discipline. Eg. If your legit expenses are £110 per week, then you could do 2x13 hour shifts @ £10ph and pay absolutely no tax EVER. This means taking home about £250pw average, as you’ll still pay around a tenner for NIC’s.
Compare that to cramming 48 hours @ £7ph, with umpteen hours on top for POA etc totalling God knows what… After tax, you’re still looking at taking home less than £300 for working more than double the hours - and that’s before the POA is included! Even 48 paid hours at my hold-out rate of £10ph will see you take home barely £400pw from pretty much maxed-out hours!
Notice I don’t mention signing on, claiming any kind of benefit, even tax credits. This is purely about minimising your personal tax bill the legitimate way - by providing receipts. Don’t let the employing firm claim expenses without them (hiding their commission in the claimback!) only to find at the end of the tax year that much of those expenses you’re told ‘you don’t need receipts’ for are actually non-legit and thus incur a hefty tax bill!
I still maintain that Mileage and Meals are the biggest areas that will come back to bite most people in the arse here.
Mileage means you HAVE to work at least at 3 separate locations throughout each and every year to keep under the ‘40% rule’.
Meals - How easy is it getting a receipt at most eateries, assuming you didn’t just take a packed lunch and a whole cool box full of tuck like just about every tramper I’ve met does?
