"If one does not sign the forms, then one is not within their jurisdiction are they? "


If you don't sign the form your employer won't know what to do,&so they will talk to the IRS.& The&IRS will tell&your employer to&take taxes out anyway, as if you were claiming 0 exemptions.&


If you are going&to sign a W-4 "exempt" there is a lot you need to know before you do.
