If you are not paying taxes, the only person you are really screwing is yourself. I keep track of miles driven, supplies purchased, cell phone, and part of my computer. Those are ligitimate deductions and I have nothing to worry about. If you are just making stuff up to not pay taxes, that just plain stupid. Eventually they will catch you, besides if nothing else you will never get any SS because you never paid in.
