New Jersey Statutes Title 17B. Insurance 17B § 32B-12

a. A member organization shall be allowed a credit against the tax imposed pursuant to section 5 of P.L.1945, c. 162 (C.54:10A-5), in an amount equal to 50% of an assessment for which a certificate of contribution has been issued pursuant to subsection i. of section 9 of this act.  1 One-fifth of that credit amount may be applied against the tax imposed pursuant to section 5 of P.L.1945, c. 162 (C.54:10A-5) for each of the five privilege periods beginning on or after the third calendar year commencing after the assessment was paid, provided however, that no member organization may reduce that tax liability pursuant to this section by more than 20% of the amount (determined without regard to any other credits allowed pursuant to law) otherwise due for a privilege period. If a member organization should cease doing business in this State, any credit amounts not yet applied against its liability may be applied against its liability for tax imposed pursuant to section 5 of P.L.1945, c. 162 (C.54:10A-5) for the privilege period that it ceases to do business in this State.

b. Any sums that are acquired by a member organization as the result of a refund from the association pursuant to subsection g. of section 9 of this act are deemed to be assessment amounts for which a credit was allowed pursuant to subsection a. of this section. If the member organization has applied any amounts of the credit allowed pursuant to subsection a. of this section, then 50% of the amount of any refund shall be paid by the member organization to the State as the Director of the Division of Taxation in the Department of the Treasury may require until the amounts paid equal the amounts applied as credit. The association shall notify the commissioner and the director of any refunds made.
