Yeah, I've used H&R's free filing for 4 years or so now. When I lived in a state with state income tax, they charged me for that, and offered to charge me to remember my data for next year (I declined). their website indicates that state tax filing is now free, I wonder if it depends on the state, or if things just changed since 2015 tax year filing.
unfortunately I don't have any other tax experiences to compare to, but it was very easy. as a student, I don't have complex deductions or income, but as long as I can use the American Opportunity Tax Credit, and it doesn't take too long, I'm happy.
