I purchased H&R Block Deluxe + State on Amazon today for $21.99. From what I can tell, this is identical to Turbotax Deluxe + State. You get five free federal e-files and one state download included.
I spent the last hour entering my 2016 YTD tax info and from what I can see so far, this software is very similar to Turbotax. The interview style, entry methods, etc all look virtually identical.
I've been a Turbotax user for more than 20 years, and I kept buying it each year out of habit, but I've always heard that the H&R Block software is just as good, and they offer free online chat to answer tax questions and a 10% Amazon bonus if you have a refund and want to take some of it in Amazon credits.
I won't know for sure whether this is really as good as Turbotax until I complete the entire process and file, but from what I've read of other reviews, everyone seems very happy with it.
The $21.99 price is a one day deal today only on Amazon, but with the typical discounts I think you can usually get it for around $30.
