> The IRS could very easily send a pre-filled tax form for most Americans to verify and sign like other countries do. All the relevant information is already reported to the IRS. One of the current problems is that the information is reported in parallel by those providers. Many small businesses print off their employees' W-2s at the same time they print their own tax returns. Yes, the IRS knows eventually. They don't know by April 15th under the current set of filing deadlines, though. That's a solvable problem, but not as trivial as you make it sound.
