There is a charge of $15 this year, if you are under 25 and have more than just a basic return then there will be a charge of $15 - the good news is that even if you upgrade the upgrades don't cost anymore than your original $15.
Not the original poster, but the only difference from the free return I filed last year is that I'm claiming FHSA benefits. Does that make it "no longer a basic return"?
