The tax planning section is very weak. Ideally, the user could compare the four options, based on how much data is entered, and the program would show the math rather than just give an answer. Currently the user needs to basically be a tax expert to understand and trust the result.
I've used H&R Block tax software for years. It's easy to use and appears to be very accurate. The Help section is not always useful as sometimes it is not specific enough. For less experienced filers, there are detailed areas that can be used to assist. For example, there is a "Deduction Pro" section that helps users decide if they should itemize. Good software overall.
Very intuitive and helpful as you go through the process. Very few times in the process where you are unsure if you've answered correctly. Even then the "?" help is very useful.
A bit difficult if you need/want to review a section or specific entry. For example: If you've sold stock and want to review the results to verify that the calculated capital gains is what you expect. In general: If you are not sure if you've provided the right answers and want to review what the software has produced/calculated it can be difficult to find and understand the forms and working documents.
