This is for the federal return. I am in a RDP and live in CA. Your statement is incorrect, we must make adjustments on the Federal return. The following are taken from IRS Form 555:
"Registered domestic partners in Nevada, Washington, or California must generally follow state community property laws and report half the combined community income of the individual and his or her registered domestic partner."
"Federal income tax withheld. As a general rule, each RDP is entitled to credit for half the income tax withheld from wages that are community property"
