We did our own taxes online again this year..and survived! Just went to the IRS site, and our state site - both are free.
And they let you know if you made a mistake (you correct and then submit again), so you can't wait until the final minute to do them. Took DH a while to understand that they weren't going to come out here and throw him in jail if we goofed somewhere.
We just followed along with what was done by the tax guy two years ago. He charged us $140 that year, so by doing them ourselves, I figure we saved $150 this year.
Cool thing last year was that the IRS and State sent us a form saying that we qualified for some other credit. We filled out the forms and got checks in the mail!
We have all kinds of extra forms, schedules, 1099's, etc. But these sites have a 'do the math' button, so that part is easy. There's also a button for the instructions for each form. Everything else is just one step at a time.
I finally got my panties unbunched, too. Hate tax time.
