It’s as good as TurboTax and the basic version is free (this includes the ability to file electronically). The premium version is $13. I paid for it this year because it will pull last year’s data into this year’s filing. I don’t know anything about filing state income taxes because we don’t have that in Texas.
Last year I used the two side-by-side and they came up with the same answers, but I found TaxAct to be slightly less tedious to use.
TurboTax online is free, but to file electronically with it costs money, so once I was convinced that TaxAct had done its job, I used it to do the filing and kissed TurboTax goodbye.
My one complaint is that it will import electronic W2’s from just one source, and that’s not what our employers use. So I had to type it all in (it’s not that much typing but I like to eliminate human error where I can).
