“Direct File provides a free, secure option for taxpayers with simple tax situations in 12 states to file their taxes directly with the IRS,” the Treasury Department said. “Direct File is easy to use, with no hidden junk fees, and works as well on a smartphone as it does on a laptop, tablet, or desktop computer. Direct File shows taxpayers the math so they can be sure that their return is accurate, and they are getting the refund they are entitled to.”
You can check whether you qualify to use the system at directfile.irs.gov. Based on the eligibility restrictions in the IRS program, the Treasury Department said it “estimates that one-third of all federal income tax returns filed could be prepared using Direct File.”
But there are many limits that would prevent taxpayers from using the system.
Not every country has the same relationship to their government. In Switzerland for example our government does not know what we own and have earned, we declare it ourselves. It is fully digital but still takes longer than 5 minutes (it usually takes me around 30 minutes with an income to declare as well a some stocks and other things).
I guess the US has a similar relationship to their government.
