I had to give up on e-filing with Free Fillable Forms last year because it claimed an arithmetic error where none existed and it would not allow me to e-file until that non-error was corrected. The same forms I ultimately generated with both TaxHawk's and H&R Block's software were identical to those I wasn't allowed to submit with FFF.
