Irritated by the UX and business model of web-based tax return preparation, I've looked into open source alternatives in the past. I hadn't come across the Open Tax Solver package mentioned in this article which looks interesting. It seems like they all rely on printing and mailing the completed returns. Is there any hope of ever being able to e-file them? I don't understand why it couldn't be possible for Free Fillable Forms to support some sort of import format.
