Nassau County

Nassau County assesses property values annually, and your property taxes are based on this assessment. If you believe your home’s value is unfair, O’Connor is here to help you.

Grievances for the next tax year must be filed during the grievance period, which runs from January to early March. With 50 years of experience, O’Connor has learned that it is most effective to file grievances annually to achieve the best results over time. We leverage our vast proprietary data resources to compile evidence supporting your reduction on both unequal appraisal and market value. We are aggressive and pursue all reasonable levels of appeal, including taking your case to the Small Claims Assessment Review (SCAR) in the New York State Supreme Court.
