My neighbour is an electrician. He isn't self employed and works for a company.
Anyway, I know his wife and she makes a joke out the fact that he earns a fortune doing homers and gets away with paying no tax. He earns decent money in his job but can do a couple of rewires a month as well as odd jobs. This can net him a few thousand extra per month. He has bought a van so he can do these homers on the side.
She jokes that the taxman will never find out and it affords them holidays, designer clothes and for her to be a sahm.
Now I have a really good job that I enjoy and my DH also has a good job. I know it shouldn't but it riles me that I am taxed at source on all my earnings and she's boasting about her husband dodging the taxman.
I can see why people would say stay well away and not report and I can see why others would report it.
WWYD?
Btw I have name changed for this.
