Very accurate and easy to use. One of my favorite features is the search bar which allows you to look up info or ask questions. The itemized checklist in all of the different tax situations is also a favorite feature that helps out tremendously during the task of filing your refund.
I've been using Turbo Tax for over 10 years and have no issues. It's reliable, I like how it keeps my past info so I'm not completely re-entering information from scratch each year, which saves so much time!
