Or the IRS could file our taxes for us for free.
The IRS can simplify the process, sure. And if you are living alone, have no children, and don't care about taking advantage of any special credits or deductions, then a "file for me" button would be fine. (Though the process for those taxpayers is already in a good place--I filed my taxes for free in about 30 minutes this year.) But if you, say, have children, the IRS will not be able to "file for you" in any meanin…
For that matter, everyone qualifies for free filing--although in practice it gets too complicated for most past some point. I know it sounds like something savages would do but it's actually possible to just fill out the forms by hand if your taxes are fairly simple.
I use an accountant who I've been using for years but if you just have a W-2, a 1099 or two, and just use the standard deduction, it'ls likely pretty simple to just fill out a 1040 form and a state tax form.
