Herkimer County Property Tax Assessment Process
Property assessments in Herkimer County are set by town assessors, not the county office. Each town's assessor values every parcel using market data and comparable sales. The county office calculates the equalization rate for each town, which adjusts for differences in assessment levels across jurisdictions. Under RPTL Section 305, the tax rate must be uniform within each town.
Tentative rolls come out by May 1 in most towns. You can review the roll and meet with your assessor if you have concerns. Grievance Day is the fourth Tuesday of May. On that date, the Board of Assessment Review hears complaints. If you do not file by Grievance Day, Small Claims Assessment Review through the courts is still available later. RPTL Section 502 requires the assessor to notify you of any change to your value before the grievance period starts.
Tax Exemptions in Herkimer County
Herkimer County property owners can apply for exemptions under the Real Property Tax Law. Basic STAR covers owner-occupied homes. Enhanced STAR is for seniors 65 and older who meet the income threshold. Veterans get partial exemptions under RPTL Sections 458-a and 458-b based on service type and local adoption.
Seniors may also qualify under RPTL Section 467 for an income-based reduction. Agricultural exemptions are available for qualifying farmland in the county's more rural towns. Forest land enrolled in the 480-a program can get reduced assessments too. All applications go to your local town assessor, typically by March 1.
Note: The county Real Property Tax Services office can confirm which exemptions each town has adopted if you are not sure what is available in your area.
Herkimer County Clerk Land Records
The Herkimer County Clerk records deeds, mortgages, and liens. The office is in Herkimer. Every property sale triggers an RP-5217 form that the clerk files and sends on to the state for the SalesWeb database.
Clerk records and property tax records work hand in hand. Ownership changes from recorded deeds update the assessment roll. If you need to trace who has owned a parcel over the years, the clerk's office has that chain of title. Checking deeds before looking at tax data can help you verify that you are pulling up the right property.
