If you are ever audited, as a transportation employee, they will consider your life's "center of gravity".

If you made an "honest mistake " they will put a tax levy and place liens on your stuff.

If they think you were evading taxes you'll find your self in court facing serious fines and possibly prison Having the full weight of the government against you is not a fun place to be. Whatever short-term gains you think you are saving you will wish 10 times over you had just played it straight.
