Well they don't check them when you submit them as they don't have all the information at the same time you do. Your W2 by law must be sent to you by the end of January I believe, however delivery to the IRS is not required by the same date.
As such fraud creeps in.
You pay Inuit because there are nearly eighty thousand pages of tax law that even IRS workers cannot properly comprehend all because politicians use the IRS as a political tool to benefit those they like and punish those they don't.
Hence why any attempt to overhaul the tax process is quickly denounced by supposed neutral groups; groups at the beck and call of powerful political interest. There is an entire FUD industry built to keep the current system to benefit of the political class and those well off enough to pay them.
Intuit doesn't know tax law better than IRS workers, they just spend lots of money lobbying Congress to prevent simplified filing processes.
Intuit is one if the powerful political interests you refer to, an integral part of the FUD system you talk about built to keep the current system as-is for their own benefit.
Wait till you try to figure taxes on employee stock purchases that you do through payroll deductions. I could not get a straight answer even from the IRS, to the point some told me to track each share back to its original purchase price and fill a form per affected shares. When you call and get a different answer each time it screams that the system is to complex.
Intuit is a convenient fall guy and nothing more. The real threat is that if the system were simpler and more open it could not be used to political advantage.
