that whole rebate thing is prolly going to make it so I get money back. (The $300/$600 thing)
My dad is a CPA and his policy is always that its better to owe money than to get money back. Reasoning: The government would never give you an interest free loan, so why should you give them one?
I don't think you need software to e-file. I think you can do it on some website (IRS?)
A heads up... lots of links with a .irs ending have been circulating as scams. All IRS stuff has a .gov ending... obviously.
