            ``(2) Joint returns.--In the case of a refund or credit 
        made or allowed under subsection (f) with respect to a joint

        with a mirror code tax system in an amount equal to the loss to 
        that possession by reason of the amendments made by this 
        section. Such amount shall be determined by the Secretary of 
        the Treasury based on information provided by the government of 
        the respective possession.
            (2) Other possessions.--The Secretary of the Treasury shall 
        make a payment to each possession of the United States which 
        does not have a mirror code tax system in an amount estimated 
        by the Secretary of the Treasury as being equal to the 
        aggregate benefits that would have been provided to residents 
        of such possession by reason of the amendments made by this 
        section if a mirror code tax system had been in effect in such 
        possession. The preceding sentence shall not apply with respect 
        to any possession of the United States unless such possession 
        has a plan, which has been approved by the Secretary of the 
        Treasury, under which such possession will promptly distribute 
        such payment to the residents of such possession.

                subsection, the term ``mirror code tax system'' means, 
                with respect to any possession of the United States, 
                the income tax system of such possession if the income 
                tax liability of the residents of such possession under 
                such system is determined by reference to the income 
                tax laws of the United States as if such possession 
                were the United States.
                    (C) Treatment of payments.--For purposes of section 
                1324(b)(2) of title 31, United States Code, the 
                payments under this subsection shall be treated in the 
                same manner as a refund due from the credit allowed 
                under section 6431 of the Internal Revenue Code of 1986 
                (as added by this section).
