It is possible. In Belgium, the tax authorities have all this information and more. The 'tax on web' site mostly fills in your tax forms itself and asks you for corrections. For a lot of the population, these corrections are minor to none, e.g. some of the smaller charity deductions are missing.
I didn't say it wasn't possible, only that this isn't information the IRS has ready access to for 331+ million people in the US. You'd need big legislative and/or regulatory changes to pipe that kind of information into the IRS.
