New Jersey Statutes Title 54. Taxation 54 § 49-11

a. If the failure to pay any such tax when due is explained to the satisfaction of the director, he may remit or waive the payment of the whole or any part of any penalty and may remit or waive the payment of any interest charge in excess of the rate of three percentage points above the prime rate including any such penalty or interest with respect to deficiency assessments made pursuant to R.S.54:49-6.

b. The director shall waive the payment of any part of any penalty or any part of any interest attributable to the taxpayer's reasonable reliance on erroneous advice furnished to the taxpayer in writing by an employee of the Division of Taxation acting in the employee's official capacity, provided that the penalty or interest did not result from a failure of the taxpayer to provide adequate or accurate information.
