Official tax-record access and jurisdiction guidanceHow to find the information
The county Tax Information Request Form first directs users to RPTSweb Public Access: search a surname or Tax ID, open the blue Tax ID, select Tax Info, then Display Details for Taxes Levied. The form separately permits a request for receipt copies and a printout of current delinquent taxes, one form per parcel. Assessment/levy display alone is not a certified full payoff.
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.
What to ask for
“I am looking for publicly available delinquent real-property tax records for Oswego County for [tax year]. Which office maintains these records? Is there an online search or downloadable list? If not, how can I request a copy, and what fees apply?”
Have the property address, parcel number, owner name, and tax year ready when searching for a particular property.
County-specific notes
Verified denotes reviewed published access instructions, including explicit staff-only balance/search routes. It does not certify a tested taxpayer query. Reviewed October 28, 2026. Current annual bills, returned unpaid taxes, re-levied school/village charges, dated filed lists, foreclosure proceedings, auctions of acquired land and surplus proceeds have different scope. Confirm recent payments and the exact record date with the custodian. No taxpayer search, public-credential login, account registration, request submission, payment or owner-list republication was performed.
