Everyone does it.

I overpaid last year, and I'm evening it out.

I need the money more than the bureaucrats do.

I refuse to give money to a government that wastes so much money on bureaucracy

Cheating on taxes is a subversive act. You deprive the government of the funds to finance repression, and you do it anonymously, so you don't become a target.

Cheating on taxes is part of my ethnic heritage. Everyone in my home country does it. I must be true to my roots.

Richard Nixon cheated, why shouldn't I?

We all cheat in different ways. Some buy politicians and have them create loopholes. I'm just taking a more direct route.
