After how long can a municipality foreclose on a tax lien?

In New Jersey, a municipality can foreclose on a tax lien after a period of six months has elapsed from the date of the tax sale. This timeline is established to give property owners time to redeem their properties by paying off the tax lien. If the property owner does not redeem the lien within that six-month window, the municipality is then in a position to initiate foreclosure proceedings to recover the owed taxes. This regulatory framework aims to balance the interests of the municipality in collecting overdue taxes with the rights of property owners to rectify their tax obligations without immediately facing severe consequences.

Other options, such as three months, one year, or one and a half years, do not align with the legal stipulations set forth in New Jersey law. The six-month period is specifically outlined in the state's statutes regarding tax lien sales and foreclosures, making it the correct answer.
