Very user friendly! It is easy to use. Instructions are clear and the forms are easy to fill out accurately. I only use it once a year - at tax time, but using this program to fill out tax forms is quick and easy. I have not had any issues. I'm sure if a person uses it a lot there are bound to be some, but I use it once a year and it works fine for my uses.
