5 stars - but I am putting in 4 right now because I need to learn how to print on larger paper which means I have to go through the instructions to figure out how. But I am very pleased so far.

It's diffcult to make some changes or fix mistakes. I have notice that it is had to find a blank form. So if you need to file say 2 941 forms. I couldn't just choose another 941 form from menu. I had to use one of my saved forms or let the site and choose to file 941 and log back in

PDF when u can't PDF
Overall, this is a great software. I use often , and find it very helpful.
I mostly enjoy being able to use this software on my cell phone, and then able to complete PDF's when normally this would not be possible.
I love this software, but it is sometimes difficult to use. The features are not as basic as I'd like.
