Herkimer County property-tax questions should begin with Real Property Tax Service when the issue is assessment, map identity, exemption status, or parcel data. That gives an owner or buyer the county-level facts before calling a town assessor or comparing one village to another. Keep the parcel ID, address, municipality, and roll year in front of you.
The next check is what kind of question you have: value, exemption, tax map, recorded deed, or payment. Each one can point to a different official office.
Keep the parcel ID, address, municipality, roll year, map result, and assessment or exemption record together. Then send the value, map, deed, or payment question to the office that handles that part.
