They encourage filing electronically now? That's news to me. I filed my taxes electronically two years ago and they apparently printed it out and then lost the paperwork, then accused me me of failing to file taxes a year later. This year I found out they lost it again. I just don't understand why they're encouraging e-filing when they can't keep track of them properly.
