Everyone is to receive a tax audit as a minimum every seven years
This is our tenth year and our first audit (investigation) began last year and is only now coming to an end
We have received a bill from taxman
He already has an idea of what I and you and everyone else earns,they have a chart that gives a minimum and maximum they have been doing it a lot longer than any of us. Even which accountant you use can trigger an investigation, we have an infamous one in our area that claims "he will never let you pay tax" yet he has the highest percentage of investigations with settlement figures as high as £59,000 and that was for a four year check on a sole trader with only six years trading
Do your work,declare your income pay your taxes and live as you want. There is no point in "hiding" what you earn because you won't be able to spend it, you can't buy a car with readies over a few grand, every time you go abroad your passport reports your movements and you can't hide the money in your kids bank
Honestly just declare it all then drive what you want buy what you want live how you want, oh yes the taxman doesn't come on his own he brings the vatman the paye lady along with the immigration and benefit people. They used to operate as separate departments that competed to recover the most money for he government but no longer. They share ALL information with each other and all recover a bit each.
Thankfully we were only left with the taxman as everyone else was satisfied we ran our business legally above board and rather well, the tax bill is next to nothing and is only for silly discrepancies our bookkeeper at the time missed (don't have a bookkeeper,employ an expensive qualified CA after all his bill is deductible) we would never have coped without the excellent guidance and support our accountant provided, imagine if hey turn up at your house.
The statement of the taxman can only go by what you put on your tax return is a bit naive, it is not a RETURN it is a claim which means it needs to be checked clarified and agreed and anyway as I said earlier he knows better than you what you should be claiming
