N.J. Stat. § 52:27-26
The governing body of any municipality in which the commission is functioning may compromise and adjust the whole or any part of any special assessments or taxes delinquent to the municipality, but nothing in this section shall be construed to impair or affect in any way the existing rights and remedies of any holder of a certificate of tax sale, representing any tax title or titles to lands in such municipality sold on account of delinquent taxes or delinquent assessments, or both.
No claims of the municipality for taxes or assessments, and interest thereon, in excess of five hundred dollars, shall be compromised without the assent in writing of the commission.
All moneys received by the municipality by compromise or adjustment of taxes or special assessments shall, if the commission so provide, be paid only to the account of the reserve fund referred to in section 52:27-25 of this title.
