Relates to base proportions in Nassau and Suffolk counties

Nassau and Suffolk cap property-tax share increases

Effective immediately, the law caps Nassau property classes’ tax shares for the 2025 assessment roll at 1% above the prior year’s adjusted shares. This applies to non-city special assessing units and approved assessing units that authorize it by local law, ordinance, or resolution. In approved Suffolk assessing units, the law adds the 2025–2026 roll to those with a 1% cap instead of the general 2% cap. When a cap limits a class’s share, local lawmakers must adjust other classes’ shares so the total equals 100%. This protects capped classes but can shift taxes to other classes; it does not cap individual property tax bills.
