I've used H&R Block software for many years. But this last year two things caused concern. One is being very careful to understand what questions are being asked. Sometimes the heading is the question. Sometimes a heading is simply a heading and the question is under the heading. Also, the software calculated underpayment penalties for both state and federal returns. The state penalty was refunded to me since it appears I did not come close to the penalty threshold. For the federal return, I pursued an option to calculate on an annual, rather than quarterly basis. This wasn't an obvious option.
Since switching from Turbo Tax years ago, preparing my taxes with Tax Cut has been a significant improvement. Besides Being much less expensive, it has been much easier and faster to use.
