N.J. Stat. § 5:10A-46
The commission may, by resolution, provide that the owner of any land, upon which any assessments for any improvement shall have been made, pay such assessments in equal yearly installments, for a number of years as may be provided by the rules and regulations of the commission, with legal interest thereon, provided that any person assessed may pay the whole of any assessment, or any balance of installments, with accrued interest thereon, at one time. If any such installment becomes due and is not paid, the whole assessment, or balance due thereon, shall become immediately due, draw interest at the rate of six percent per annum, and be collected in the same manner as is provided in sections 1 through 68 of P.L. 2015, c. 19(C.5:10A-1 et seq.) for other past due assessments.
