But the IRS gets to bear the brunt of any complexity in the tax code, and they've already suggested free filing. They also clearly already know what to expect in significant detail anyway, since they adjusted my return last year.
This was part of my point with Belgium elsewhere in the tread: Belgium has tremendously intricate (and sensitive) governmental structure, but that hasn't prevented them from making tax filing a postcard for virtually everyone. The actual tax code is a lot more complex than the postcard (though still far less complex than the US' tax code), but the tax authority does the math, suggests a number, and if you have some reason to dispute it you go file a "proper" return. So: yes, maybe we can make the tax code simpler, but that should not preclude us from making _filing_ simpler regardless of how complex the tax code is.
