It is patently obvious that a tradesperson asking for cash is hoping to dodge tax and by paying cash you are colluding in this fraud. Why all this talk of cheques? Nobody uses them in business anymore, most companies, however small take payments by online banking. I have a small business so I know. The majority of my clients get sent an invoice by email, and then pay direct to my bank account, a few send me a cheque which is a pain and costs me £1 each to deposit. Nobody pays me cash, I do not want it. I just do not understand how anyone can keep a set of accurate accounts if they have got cash coming in all over the place, no invoices, and then paying out for materials. This is how so many small tradespeople go bust. I am with gillybob on this one, all of you paying your plumber, electrician, brickie in cash are helping them to avoid VAT at the very least, and make it very unfair on companies who do things the right way and issue invoices. Apart from my irritation at this, what do you think will happen to any guarantees on the work? What proof do you have that the work has been done by a registered tradesperson if you have difficulties with for example your house insurance?
