I owe every year. I have one full time job that eats up the lower end tax bracket, claim 0, and a second part time job, and I get taxed to the hilt (claim 0 on that one too). It sucks.
My guess is people are going to stop paying taxes. A 40 year old friend of mine, ALWAYS paid taxes, always worked, was laid off in May 08. Still unemployed and took money out of his retirement. The IRS wants $6K and he says he does not have it. So, he is not filing. My guess is we are going to see a helluva lot more tax evaders this year.
