"Advance tax payment credit" means credit for payments made by an A-1, A-1c, or B-1 permit holder and any other persons during the period covered by a report which was made in anticipation of the tax liability required to be reported on that report.
"Tax liability" as used in division (A) of this section means the total gross tax liability of an A-1, A-1c, or B-1 permit holder and any other persons for the period covered by a report before any allowance for credits and discount.
