Tax filing is due by midnight tonight.
(In almost all cases.)
If you're not filing your taxes today, file an automatic extension.
The tax burden in the United States is one of the lowest of any first world nation.
PAY YOUR TAXES.
The "rebate" you are getting -- the so-called economic stimulus package -- is coming off of your next year's (2008's) tax refund. Seriously. It is not a gift, unless you are so poor you don't normally pay taxes. It is an advance.
Thank you, Bush Administration. Yes, they are screwing you over yet again, on their way out the door. Why are you even slightly surprised?
