Here in Australia (as in other countries mentioned in this thread) filing taxes on the government-provided website is super easy. Wait a few weeks to a couple of months after the start of the financial year and most of the fields will be pre-filled from employers, banks, investment accounts, and IIRC private health (if any). Just need to fill in deductions and hit Submit. I don't see any technical reason the US government couldn't build something similar.
