The Assessment Roll is a report released annually that lists the ownership and assessment information for all real property within a given Assessing Unit (Town, Village, School District, etc). It is released tentatively on May 1st every year and is offered to the public for inspection. After grievances are filed on or around the fourth Tuesday in May, and corrections made, the Final Assessment Roll is released on July 1st. The Tax Roll is the same as the Final Roll, but with the amount of taxes levied against each parcel included.
All rolls are provided in .pdf format on this page. Physical copies of the roll are available at your local Assessor's office. Digital copies of the roll are available at the Oswego County Office of Real Property Tax Service.
Tentative rolls will be available May 1st, 2017.
