a. In addition to the tax on net premiums paid pursuant to section 1 of P.L.1945, c.132 (C. 54:18A-1), each taxpayer under that section shall pay to the Director of the Division of Taxation an annual surtax at a rate of 5%, or a rate adjusted pursuant to section 77 of this 1990 amendatory and supplementary act, on all taxable premiums collected in this State, except premiums collected by the New Jersey Automobile Full Insurance Underwriting Association created pursuant to section 16 of P.L.1983, c.65 (C. 17:30E-4), and premiums collected by the Market Transition Facility created pursuant to section 88 of P.L.1990, c.8 (C. 17:33B-11), in calendar years 1990, 1991 and 1992 for contracts of automobile insurance, notwithstanding section 6 of P.L.1945, c.132 (C. 54:18A-6). The surtax shall be administered pursuant to the provisions of P.L.1945, c.132 (C. 54:18A-1 et seq.), except that if any provision of that act is in conflict with a specific provision of this 1990 amendatory and supplementary act, the provision or provisions of this 1990 amendatory and supplementary act shall govern.

b. For the purposes of sections 76 through 78 of this 1990 amendatory and supplementary act:

“Automobile” means a private passenger automobile of a private passenger or station wagon type that is owned or hired, and is neither used as a public or livery conveyance for passengers nor rented to others with a driver; a motor vehicle with a pickup body, a delivery sedan, a van, or a panel truck or a camper type vehicle used for recreational purposes, owned by an individual or by husband and wife who are residents of the same household, not customarily used in the occupation, profession or business of the insured other than farming or ranching. An automobile owned by a farm family copartnership or corporation, which is principally garaged on a farm or ranch and otherwise meets the definition contained in this section, shall be considered a private passenger automobile owned by two or more relatives resident in the same household; and

“Automobile insurance” means direct insurance against injury or damage, including the legal liability therefor, arising out of the ownership, operation, maintenance or use of an automobile, including, but not limited to, personal injury protection insurance, bodily injury liability insurance, property damage liability insurance, physical damage insurance and uninsured and underinsured motorist insurance.

c. Each taxpayer shall:

(1) on or before the first day of the third month following enactment of this 1990 amendatory and supplementary act make an installment payment of surtax due under subsection a. of this section in an amount equal to one half of the surtax estimated to be due for taxable premiums collected in this State in calendar year 1990 if the surtax rate at the time of the payment was imposed for the entire year; and

(2) on or before the first day of the sixth month following enactment of this 1990 amendatory and supplementary act, make an installment payment of surtax due under subsection a. of this section in an amount equal to one half of the surtax estimated to be due for taxable premiums collected in this State in calendar year 1990 if the surtax rate at the time of the payment was imposed for the entire year;

provided however, that no installment payment shall be due if the payment date of such installment pursuant to this subsection falls on or after February 1, 1991.

In the calculation of the tax due in accordance with subsection a. of this section, a taxpayer shall be entitled to a credit in the amount of the tax paid under this subsection as a partial payment and shall be entitled to the return of any amount so paid which is in excess of the total amount payable in accordance with this section.

d. Failure to pay any installment payment required pursuant to subsection c. of this section shall constitute a deficiency, and there shall be added to the tax for the calendar year interest on the amount of underpayment as provided in the State Tax Uniform Procedure Law, R.S.54:48-1 et seq., for the period of the underpayment.

The amount of underpayment shall be the excess of the amount of the installment payment which would be required to be paid if the installment payment were equal to 45% of the surtax which would be shown on the return for the year if the surtax rate at the time of the payment were imposed for the entire year, or if no return was filed, 45% of the tax for that year, over the amount, if any, of the installment payment paid on or before the last date prescribed for payment.

For purposes of this subsection, the period of the underpayment shall run from the date the installment payment was required to be paid to the earlier of the date on which the surtax is due pursuant to subsection a. of this section or, with respect to any portion of the underpayment, the date on which that portion is paid.

For purposes of this subsection, a payment of any installment payment shall be considered a payment of any previous underpayment only to the extent that such payment exceeds the amount of the installment payment determined under this subsection for that installment payment.

e. All revenues collected from the surtax imposed pursuant to this section, less any refunds paid pursuant to subsection d. of section 77 of this 1990 amendatory and supplementary act, shall be credited by the State Treasurer to the New Jersey Automobile Insurance Guaranty Fund, created pursuant to section 23 of this 1990 amendatory and supplementary act.
