Good question that "Why is it you can not file by mail?".
Actually, over the past few years have been filing Federal Tax Return online thru Free File Fillable Forms and it has been very convenient to file even at a later date say 10th Apr i.e. still before the due date of 15th Apr.
For filing thru mail, need to dispatch atleast 2-3 weeks prior to Due Date which means need to start working on it by mid-Mar. Since this time, IRS changed the Free File Fillable Forms rqmts which I got to know on Apr 10th, so now thru mail, it would reach later than due date of 15th Apr. So trying to explore how to submit the Federal tax Return online and free?
