The Assessor’s Office of the Town of Big Flats is responsible for the valuation of all of the property within the town. These values are converted into estimates of property value, assessments, that are used in the computation of real property tax bills. This office is charged with maintaining property record files on 3,600 individual parcels as well as preparing assessment and property tax levy rolls for the town, Chemung County, and four school districts, HorseheadsCorning City SchoolsElmira Heights, and Elmira City Schools. This office also administers a wide program of property tax exemptions for the benefit of town residents and business owners.

It is the goal of the Assessor’s Office to maintain the highest standards of assessment practice and to provide the Town’s property owners with accurate and fair assessments. Property record collection standards are being upgraded to Uniform Standards for Professional Practice (USPAP) requirements. In so doing, much of the mystery and confusion surrounding assessments and their associated taxes should be diminished. Assessment practice should be transparent and this office will do everything possible to educate and assist our property-owning public.
