Have been using software from H&R Block for about ten years. There have been few issues with filing my taxes and that includes three different states at different times. It provides good value for the price.
Have used TTax since their inception. Decided to try H&R Block this year due to lower cost. Pleasantly surprised and will order at next year Black Friday offer.
I've used H&R Block Deluxe + State to prepare my yearly state and federal tax returns since 2015. Like the format and features of the software, especially the ease of electronic return filing.
Pros: Easy to prepare, Maximizes refund, Easy to import documents, Fast
