Now That’s what I call Taxation without Representation.
I have two kids, a stay at home wife and a home that's paid for. I don't owe anyone anything, my only expenses are my monthly living costs (food, electricity, etc..) The day after Obama was elected, I changed my withholding to 10. I'm not giving the Government my money, period.
My suggestion: Everyone reading this thread change their withholding for 2010 to the maximum they comfortably can and keep as much of their money as possible. The amount you'd expect to pay in taxes (look at the previous year's W2) put in the bank and wait until next Tax Day.
Don't ever give this Government your money a second before you absolutely, positively have to. If they had to wait until April 15th to get ANY of our tax dollars it sure as hell would change their behavior.
