I believe there's no fine if the difference is $500 or less, or if it's more, but last year it wasn't.  

It probably would make a noticeable difference if we all adjusted our withholdings so that we didn't get any tax returns, or even owned a small amount on April 15.  

OTOH, the federal government is already so deeply in debt, they may not even notice more.  

I like the idea pushing states' rights.  It is a GOP position.  They wouldn't fight it.  It's something that might pass.
