Local Boards of Assessment Review to Meet in May/June
For those wishing to challenge their 2024 tentative assessed values the first step in administrative review is to meet with your local Board of Assessment Review (BAR). Most BARs meet on the fourth Tuesday in May (5/28/2024), however that date may differ if your municipality employs an assessor who serves in more than one town. This list contains all the grievance date and times around Oswego County. If you are challenging your assessment this year you MUST meet with this Board in order to move onto any subsequent complaint route in the future.
The department of Real Property Tax Services is an administrative agency of Oswego County that is tasked with maintaining county tax maps, real property related geographic information data, and administration of Geographic Information Systems (GIS). Our office also provides services and support to the local assessment community, local governments, and school districts in the administration of assessment rolls and property taxes.

Please note that our office does not set or approve assessments, collect property taxes, or keep records of tax bills or receipts. For those topics please click or tap the following:

Your city or town has an appointed official known as an "Assessor" who set assessments, approves exemptions, and maintains the Assessment Roll. Assessment records are publicly available online. For assessment related questions please contact your local City or Town Assessor.

All property taxes are collected locally by your city, town, village, or school tax collector. For tax related questions during the standard period of local collection, please contact your local tax collector.

In the City of Fulton the Fulton City Chamberlain is the tax enforcing agent for Fulton property taxes (including County and School tax). In all other municipalities (towns, villages, school districts, and the City of Oswego) the County Treasurer is the tax enforcing agent for delinquent property taxes.

Many muncicipalities and school districts have put their tax records online. You may also view original billed amounts, copies of County tax bills, and delinquent payment status on the real property database by clicking "Tax Info" after searching for a property.
