Washington County Treasurer’s Office
Official published property-tax record access guidanceHow to find the information
The Treasurer offers Find My Tax Bill & Pay Taxes Online and Tax Inquiry. Municipal instructions endorse the county Ascent Land Records Suite for bills, payment status and receipts, while second-half county collection differs from initial local collection. Use the county’s current link and ask for the existing dated unpaid ledger, missing years and later costs; an older municipal deadline should not be applied to a different bill year.
Identify the county, municipality, real-estate parcel/account number, tax years and desired as-of date. Ask for the existing unpaid collection ledger or dated statement showing principal, included levies/special assessments, payments, interest, penalties and later costs. Confirm whether the municipality still holds that year or the county has taken over. An ordinary bill, paid receipt, assessment roll, tax certificate, In Rem case, redemption calculation, tax-deeded property list and surplus-proceeds distribution are separate records. For enforcement or a completed sale, ask the Treasurer to identify the applicable court/county custodian and request the dated notice, case/sale record or funds record. Confirm available existing formats and copy/certification charges before ordering.
