Sec. 7. (a) As used in this section, the credit of a carrier for any quarter is the amount by which the credit to which the carrier is entitled under section 6 of this chapter for that quarter exceeds the tax liability of the carrier under section 4 of this chapter and section 4.5 of this chapter (before its repeal) for that quarter.
