If you were around last year, you know I'm a big advocate of free e-filing. If you made under $56,000 in 2008, go to http://www.irs.gov/efile/article/0,,id=118986,00.html
You'll be able to e-file for free. Once again if you live in Indiana, you'll be able to "i-file" for free no matter how much you make. www.in.gov for that one.
Last, but not least, if you have a tax question, you can go to hrblock.com and have it answered for free until Jan 31st. We all hate doing it, but knowing these tips might make it a little less painful.
