It's easier to do it on paper, using the PDF forms.
Last year was the first and hopefully the last year I did taxes electronically. To prepare, I filled out the government's PDF forms. Then I had to research the online filing options, picked one, set up an account and filled in all the info I'd already entered into the PDF forms, had it fail on me, picked another, gave personal info to yet another online account, had to enter all the tax data again, and then had it tell me it'd take two days to confirm acceptance, which if it had failed, would have made me late.
This year I just printed the damned PDFs I'd already filled out and snail mailed them on the way to work.
Just because it's "on the computer" doesn't make it any easier.
