The Town of Plattsburgh Assessment Office is responsible for administering NYS Real Property Tax Law.  This includes real property tax exemptions authorized under state and local laws such as partial exemptions for veterans, agricultural, senior citizens with limited income, physically disabled people with limited income, solar and wind energy systems, and STAR (school tax relief).

The Assessment Office is also tasked to ensure that the tax burden is distributed equitably among all property owners. This involves establishing the value of real property so that school, county, town, and special district taxes may be equitably apportioned among property owners.

The Assessment Process

New York State Law requires all properties in every municipality (except in New York City and Nassau County) to be assessed at a uniform percentage of market value each year. This means that all properties in your city, town or village must be assessed at market value or all at the same uniform percentage of market value each year.

State Law also requires your assessor to include the estimate of the market value for each property, the assessment for each property and the uniform percentage for all taxable property on the tentative assessment roll.

At any time, a property owner believes the assessed value of their property to be inequitable or disproportionate compared to the market value and similar homes in their neighborhood, they should first contact the assessor for a review. They should be prepared to provide documentation to show why they believe the assessed value is unequal or excessive.

If the property owner wishes to pursue a claim further, it must be filed with the Supreme Court in Clinton County. There are two choices, either by means of a Small Claims Assessment Review – for one, two, or three family owner-occupied (non-condominium) residences or for lots too small for building, or by filing a writ of certiorari for all other types of property – the path generally taken for larger properties.
