Thought I'd give my personal review on this topic...for what that's worth...
I just finished doing our taxes with TaxAct. My wife asked about it on her Travel Agency's Facebook page, and several people gave it rave reviews...so...I went ahead with it.
For anyone interested...
I wouldn't personally recommend TaxAct unless you're a stickler for details; which means, paying EXTREMELY close attention to "options" rather than being asked specific questions (like TurboTax and H&R Block does) to complete the different steps.
Compared to TurboTax and even H&R Block, it's EXTREMELY easy to miss deductions and even pertinent information that's required. It took me about 2 1/2 hours to fill out our taxes with TaxAct; whereas, TurboTax and H&R Block took roughly 1 1/2 hours...give or take. I had to keep going back and filling in information that I missed. Plus, it asked me for information at one point, then when I got ready to e-file, I had to enter the same information with even more detail...too much to explain!
Now, I'm basing this off of past experiences with both TurboTax and H&R Block, so there could be some changes in both of them that I'm unaware of.
Total finished cost was $70. Not enough savings for the problems I ran into...but that's me.
They asked for a rating of 1 - 10 as to whether I'd recommend it to others...I gave it a 5.
