Tax Preparation Software

I use Tax Act as well. Since our return is very complicated involving Business income, Chld tax Credit , Dependent Care, tuition ans etch, we pay a very small fee for efiling.
This software let us do Business Income( Schedule C) when most do not.

I use Tax Act and I like it. I have pretty simple taxes though. It's free, but if you want help and some of the upgrades, you have to pay. I choose to pay, it's a small fee and can save you thousands of dollars like it did for me.

It caught a little mistake I made which had deducted almost $3000 from my return.

I know Turbo Tax is expensive, but my brother who is a CPA said it is the best one on the market for doing your own taxes.

I've used TaxAct.com the last few years. Depending on your AGI, it could be free. I think the cut off is $50,000. If you want to file your state taxes electronically, I think there is a small fee for that. Or you can print your state return for free and mail it in.
I've never had any problems with it. And I have been quite pleased with how simple it is.
I just did our 2009 taxes tonight with TaxAct and it was a piece of cake. :)
