PROPERTY TAX RESEARCH, MADE SIMPLER
Mason County, Washington
Where to look, which office to contact, and how to request records.
Where to obtain records
Mason County Treasurer’s Office
Official published tax-record and foreclosure-record access guidanceHow to find the information
The county’s foreclosure information sheet says title reports, once received, are available for review in the Treasurer’s Office and gives the Foreclosure Deputy at this extension. It separates tax-foreclosure property, later county-held Tax Surplus property and surplus money after a sale. Ask for the applicable current notice, dated unpaid ledger and record-copy procedure. Public delinquent-account search fields and full online unpaid-roll coverage were not established from this document.
Identify the real-property parcel/account number, tax years, levies or special assessments and desired as-of date. Request the existing unpaid ledger or dated tax statement with included payments, interest and enforcement costs. A normal bill, assessed-value record, foreclosure certificate, dated bid list, completed-sale result and county-held tax-title inventory are different records. For foreclosure, ask for the court case, notice, applicable redemption calculation and payment cutoff. Excess/surplus sale proceeds are a funds/distribution record, distinct from surplus real property. Ask the Treasurer to identify any separate district or court custodian and confirm the available existing format and copy/certification cost before ordering.
What to ask for
“I am looking for publicly available delinquent real-property tax records for Mason 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.

No taxpayer searches, logins, registrations, record requests, payments, declarations or owner-list republication performed.
