Even as someone that's always reduced my tax liability within guidelines I'm not going to criticise anybody that doesn't declare their earnings.
But as I've had a tax investigation I'd advise against it,you really don't want one and I won mine.
I think there is an underlying feeling that WGs bank stack loads of cash and don't declare it,I don't believe this is a case.I can't seem to do any sort of large cash transaction without the Spanish Inquisition from any of the banks I use.
As for buying anything of value in cash nobody wants it.
I've had a couple of tax investigations, income tax when I was 24 years old. Nothing to worry about as I was 100% legitimate. What I found interesting was the questions they ask, things like do you own any artworks, precious gems, antiques. I suppose they were all relatively untraceable back then, and they were trying to get a list of assets for future reference.
Second investigation was a company investigation, coincidentally not long after I had an acrimonious split from a business partner. Nothing to worry about again as we were totally legitimate.
I did have an unscheduled visit from the VAT office. It was an unusual reason, we bought a huge amount of stock right at the end of the VAT quarter and when we submitted the return it resulted in a refund request. Again, we had nothing to worry about, much to the visible disappointment of the inspector.
I have only had a couple of occasions recently where I have accepted cash payments (circa £10k) I had no problem paying in to my Metrobank account. It was different when I tried to pay £4,500 in to a personal Lloyd's account, I was grilled and advised that they won't accept more than£500 in future.
I also find that nobody wants cash any more.
