I think people overestimate the time savings with pre-filled tax forms. I've filed taxes in countries that "auto-complete" your return. What I end up doing in that case is pulling all the forms I received, double checking all the numbers, and if they are correct, hitting "submit". So I basically end up doing the return anyways. That said it was much simpler - but not because the form was already filled out, but because the tax code was way simpler. If the IRS starts auto-completing forms, people are either going to still have to "do their taxes" or just take the risk that the numbers are right. If you had a super simple return to start with, it wasn't much work anyways.
