Tompkins County points the public to Beacon for real-property data. Beacon can show property values, assessment details, ownership, sketches, and tax maps. The county also posts assessment rolls by municipality and year, including tentative and final rolls. Use the PDF roll to match the parcel’s assessed value to the formal annual record instead of relying only on the map view.
Search Beacon, note the parcel identifier and municipality, then compare the result with the current tentative or final roll before raising a question with Assessment. Keep the address, parcel, owner, permit, or job number with the date you checked it before treating the answer as final.
Save the Tompkins County Beacon result with the parcel number, lookup date, and matching tentative or final assessment roll. Keep the roll year with the record when asking the county about the assessed value.
