Trust me doing sneaky things around the IRS is a bad move. You do not want the IRS crawling all over you from everything to suspicious bank withdrawels (consistent and frequent withdrawels under officially notified values of 10000 dollars) to suspicious employee classifications. Its best to make larger withdrawels and just say you are doing it. Makes you look less guilty.
The government has nothing if not a great deal of power if you get noticed, your life will become misearable. Filling the requisite paper work is very important.
I mean Lockheed Martin was beaten to a bloody pulp over their ethics and money problems, hell they made laws because of them and they are the largest defense contractor in the world, and they have 120,000 employees, imagine what happens when the government sledgehammers a single person.
