Perhaps. But then, you might just be shifting the tax cheating from "not paying income tax" to "not paying sales tax". (E.g. more private sales where the retailer doesn't charge the required taxes.)
Maybe, but the incentives are in the right direction. A person preparing his/her own taxes has a lot of incentive to cheat. However a retail outlet has no incentive to diminish sales taxes for any buyer - in fact, they have a significant incentive NOT to.
The problem with a national sales tax is that it is quite regressive. I suppose there are ways to mitigate that but it becomes complicated.
There are state sales taxes on almost all items except necessities like food. But there are no sales taxes on the buying and selling of stocks and bonds. I think a small tax (a quarter of a cent per 1000 shares?) would be progressive and would have other benefits for the individual investor. I'm sure it doesn't exist because damn near every lobbyist and congresscritter would be hit by it so it is DOA.
