Off the books is getting harder and harder. I live in an area of the UK with basically no uber coverage (just to avoid confounding factors) and every taxi driver wants me to pay cash even though I never carry any - simply because taxi drivers have always had a small or large undeclared income. The corollary of this is that taxi drivers cannot raise their rates because that is regulated - and regulated at a level that was set when cash was common and so would be a level that baked in the tax fraud. A strange catch-22 but one I suspect is growing. As more of the world is online payments or nfc payments the less wriggle room there is.
