I have used this product for several years. The interview covers about 98% of required tax information. However, it seems as though there are always one or two items on which I have to make a manual entry. I'm familiar with taxes, so it's okay for me but some people might struggle.
It is mostly user friendly to use the program but still have not heard back about a claim made in Dec. due to MO tax not paid & had pay penalty & interest.
I trust H&R Block tax software. I have been using it for my personal and self-employment taxes for well over 10 years and find it easy to use and always accurate. I really like that it first copies basic info from previous year's taxes and then asks you to verify or update for the new year.
Pros: Easy to prepare, Maximizes refund, Easy to import documents
