Cheating on one’s taxes is as simple as paying someone under the table. Very much akin to taking your wallet out of your back pocket and putting it in front while in a crowd.
I am Mr. Law and Order, but whenever I use the services of someone who is self employed (mechanic, carpenter, barber, etc.)I pay them in cash if at all possible. I couldn’t care less whether they report it on their taxes or not. All of my income is entirely too documented to anything shady.
