(a) N.J.S.A. 54:10A-15.4 imposes an addition to the tax on the amount of the underpayment of any installment of estimated tax by a corporation (with certain exceptions). This addition to the tax is imposed irrespective of any reason for the underpayment. The amount of the underpayment for any installment date is the excess of:
(b) Interest is determined at the annual rate referred to in (c) below based upon the amount of the underpayment of any installment of estimated tax for the period from the date such installment was required to be paid until the 15th day of the fourth month following the close of the tax year, or the date such underpayment was received by the Director, whichever is earlier. For purposes of determining the period of the underpayment:
(c) The rate to be used at (b) above is an annual rate of five percent above the prime rate, compounded daily from the date the tax was originally due and payable until the date of payment. On and after July 1, 1993, the rate is three percent above the prime rate compounded annually. Each such underpayment shall bear interest at the rate prescribed above. The following is an example of underpayment interest computation:
Item (1) | Tax on return for the current year................. | $200,000 |
Item (2) | Ninety percent of item (1)....................... | 180,000 |
Item (3) | Amount of estimated tax required to be paid on each installment date (25 percent of $180,000).. | 45,000 |
Item (4) | Deduct amount paid on each installment date...... | 32,500 |
Item (5) | Amount of underpayment for each installment date (item (3) minus item (4))..... | 32,500 |
Item (6) | Interest shall be charged on each underpayment at the rate as prescribed in this subsection |
Second installment: Interest period June 15 of the current year to April 15 of the following year
Third installment: Interest period September 15 of the current year to April 15 of the following year
Fourth installment: Interest period December 15 of the current year to April 15 of the following year
(d) If there has been an underpayment of estimated tax as of the installment date prescribed for its payment and the taxpayer believes that one or more of the exceptions described at (e) below precludes the imposition of the addition to the tax, it should attach to its New Jersey corporation business tax return, for the taxable year a Form CBT-160 showing the applicability of any exception upon which the taxpayer relied.
(e) Exceptions to imposition of interest on underpayment of an installment payment. The addition to the tax under this rule will not be imposed for any underpayment of any installment of estimated tax if, on or before the date prescribed for payment of the installment, the total amount of all payments of estimated tax made equaled or exceeded the amount which would have been required to be paid on or before such date if the estimated tax were the least of the following amounts:
