I've been using Turbo Tax since 1997 and have always been completely satisfied. The ability to download financial information from financial institutions is a nice feature and saves a considerable amount of time. The program's step-by-step walk through approach is very easy to follow and covers everything, even things that are often overlooked. The on-line help is good and usually answers the question. Over the years, I've experienced a few technical issues with the NH state program, but they are easily overcome by reverting to the form itself and directly overriding the information. I would, and have, recommended Turbo Tax to my friends.
What's great about it: Accurate calculations, Prefills from prior year's info, Downloads of fianacial data from financial institutes, Good help
What's not so great: Some data does not feed back to "Summary Page" Tax exempt Int/Div; NH DP-10-ES wks does not total - no form generated
This is my fourth year of using Turbo Tax. I have never had a problem with the software or the e-filing. Turbo always walk be thru the steps and it is extremely easy to go back and correct a mistake without having to back to ground zero.
