STAR Property Tax Relief Program

***March 1st is the deadline for filing all new and renewal exemption applications***



The City Assessor’s office is responsible for maintaining and updating property records for all parcels of property within the City of Olean. We review new construction and demolitions, record sales, help to maintain property tax maps by working in cooperation with Cattaraugus County Real Property Services, prepare annual Assessment Rolls, County and City tax rolls, and mail out tax bills. We also provide information to property owners, appraisers, realtors, attorneys, developers, government agencies and a variety of other organizations within the community.

Most of our records are public information, much of which is contained on this website. In addition, we also process exemption applications such as Senior Citizen, STAR, Veterans’, business improvement 485B, and others, in accordance with state guidelines.
