State aid

To encourage fair, transparent and efficient assessing practices, ORPTS offers aid programs to localities. In part, these aid programs are designed to help local governments make improvements in assessment administration.

Aid for cyclical reassessments

The Aid for Cyclical Reassessments program encourages localities to provide fair assessment to protect their initial investments in quality assessment rolls. To be eligible, assessing units must commit to conducting reappraisals of all property at least once every four years. Up to $5 per parcel is available in the year of a full reappraisal.

For fiscal year 2024-2025, up to $750,000 in aid is available. Aid is only payable to assessing units conducting a reassessment that have not received aid in the previous two years.


Due to the funding limitations, localities should not file applications for assistance for 2024 unless they are conducting a full reappraisal in 2024 and have not received aid in 2022 or 2023. Interim assistance of up to $2 per parcel is not available this year.

Plans for cyclical reassessments

To remain eligible for assistance, any changes to plans with respect to a reappraisal cycle must be submitted no later than 120 days prior to tentative assessment roll date. For municipalities on a standard assessment calendar, changes for the 2025 roll need to be filed by December 31, 2024.

If you have any questions regarding state assistance or amending your plan, contact your ORPTS customer service team.

Examples of reappraisal

Examples of reappraisal plans and aid for cyclical reassessments
Reappraisal Plan Year 1 Year 2 Year 3 Year 4 Year 5
4-year plan * Reappraisal $5 Reappraisal $5
5-year plan ** (Maximum time between reappraisals) Reappraisal $5 Reappraisal $5

* Minimum plan length is 4 years; reappraisals are required in the first and last years
** The maximum time between reappraisals is 4 years

Consolidation incentive aid

Two or more assessing units are eligible to receive a one-time payment of up to $7 per parcel if they assess all property at a uniform percentage and merge their assessment functions by doing one of the following:

  • Combining to form a consolidated assessing unit by employing a single assessor, preparing a single assessment roll, assessing at a uniform percentage, conducting reassessments at the same time and having a single Board of Assessment Review.
  • Coordinating the assessing function to form a coordinated assessment program by either employing a single assessor or contracting with the county to provide assessment services, specifying the same uniform percentage of value for all assessments and using the same assessment calendar.
  • Forming a county assessing unit.

The objective of this program is to reduce the number of assessing jurisdictions in New York State in an effort to improve the efficiency in the administration of the real property tax. Each of the approaches described above will also provide a way for smaller municipalities to reduce the cost of reassessment, facilitate acquisition of new technology and obtain valuation expertise.
