Right. Filing taxes should only be necessary if you have itemized writeoffs or wish to contest the IRS's statement of your tax liability. They already know what you earned their your employer, what's been paid in taxes, what basic credits your qualify for, etc. They know what you owe so long as you didn't have expenses to apply for that they couldn't assume or know about. The only reason they don't already do that or, at least until now, have a free public system for filing, it's because tax companies have lobbied for decades to be able to milk the public for cash to help them file and navigate their tax liability.
