Nassau Assessment Reviews Follow the Roll Calendar
Nassau owners should check the tentative roll, ARC filing window, final roll, and AROW status before choosing a next step.

Nassau County assessment disputes move on a tax-year calendar, so the roll date matters. The 2027/28 tentative roll was published on January 2, 2026 and listed the ARC appeal period as January 2 through March 2, 2026, with ARC review running afterward and the final roll due April 1, 2027. AROW also posted that the filing deadline for that tax year was extended to March 31, 2026. The lesson is to check both the calendar and AROW, because the filing window can shift.
After the grievance period, use the final-roll date and appeal status to decide what question remains.
Use the calendar and roll for the assessment-review deadline. Tax payments, title, permits, inspections, and court matters follow different records.
Match the Nassau County assessment notice to the Assessment Review Calendar. Keep the property address, parcel or account number, tentative or final roll, grievance papers, search date, and deadline together.
