OnCor is a cooperative project between the Ontario County Real Property Tax Services, Information Services/GIS Program, Planning Department, Clerks Office, and County Public Works. The program leverages the resources of these individual departments and delivers them through one common web enabled interface.
Please note that tax bills are now provided where available, but these are for informational purposes only and are not intended to replace official documents. While assessment information is also shown, users are strongly urged to contact the Ontario County Treasurer's Office (585-396-4432) to verify exact total taxes.
