A Nassau homeowner with unpaid property taxes should use the county’s unpaid-tax reports and annual tax lien sale page early. The annual sale covers certain real estate tax liens unless the owner or another interested party pays the total unpaid taxes, assessments, interest, penalties, expenses, and charges by the posted deadline. The county also provides information for open tax liens and delinquent taxes.
Nassau distinguishes between a lien owned by a third-party investor or the county and a delinquent tax item that was not sold. Know which bucket the property is in before calling for help.
Match the section, block, lot, address, and tax year to the current unpaid-tax report. Keep the notice, total amount due, posted deadline, lien owner, and every Treasurer or attorney response together. Do not send payment until the correct payoff route is confirmed.
