I noticed that you have a Massachusetts phone number .. I'm actually from Cambridge, MA and attended Bentley(college) University in Waltam, where I studied Accounting&Finance and now runs my own tax preparations and financial services firm here in Northern Virginia.

very difficult to use -and the system does not total the # on each page like turbo tax does -not user friendly -hard to go back to add forms -that you did not originally prepare

I used the service like the service, but until I got to print a copy of the SR-1 form, I thought I was using the government's free website for submitting an SR-1 form. I want to cancel it because I will not need to use it again. So, please cancel my account and service. Please also send an email to me confirming that you have cancelled the service. Thank you.

I had a surprisingly positive…
I had a surprisingly positive experience when I discovered that I had a subscription after several months of notifications being filtered into my spam folder. When I contacted the company, I received a prompt and thorough response. I wasn’t hassled or blamed; instead, I felt understood and supported. My account was canceled for me, and I was informed that I would receive a full refund. It was a great relief to be treated with such understanding. Thank you!

I know there is more to learn and if I had the time to learn it, I would, but I just don't have the time, am in the middle of moving, so I can't do it.

a little hard to figure out at first but once I got the hang of it was great. Like the variety offorms tonselect from, some forms could be a bit more specific but other than thaat I love the program.
