PROPERTY TAX RESEARCH, MADE SIMPLER
Montgomery County, New York
Where to look, which office to contact, and how to request records.
Where to obtain records
Montgomery County Treasurer
Confirmed office route; online delinquency coverage unconfirmedContact the office for delinquent property tax records. This guide does not confirm an online search or current bill list.
How to find the information
The official Treasurer contact page confirms the office in Fonda, and the department describes answering delinquent-tax questions. Contact it to establish inspection/copy arrangements for the existing unpaid real-property ledger, dated tax-search document and foreclosure records. A public delinquent-account database, supported search fields, retained years and electronic countywide report were not confirmed.
For existing records, provide the municipality, parcel/Tax ID or SBL (BBL in NYC), tax years, taxing district and desired as-of date. Specify an unpaid collection ledger, dated filed delinquent list, tax-search certificate, foreclosure petition/judgment, auction result, redemption calculation or surplus/proceeds record. Ask which local, county, school, village and special charges are included, whether a charge was re-levied, and how later payments and costs are reflected. Confirm the records custodian and available inspection/electronic-copy process. Ask for existing reports; do not assume a custom countywide extract will be created. Confirm copy, search, certification and extraction charges before ordering.
