County Assessor: Ownership, Values, and Parcel Data

The Benton County Assessor’s Office is responsible for determining the value of all taxable real and personal property in the County. Washington State law requires assessing all properties at 100% of fair market value. In addition, the Assessor’s Office manages accessible property information, provides timely and accurate assessments for tax purposes, and maintains a detailed parcel map of all parcels within the County.

County Treasurer: Taxes, Bills, and Payments

The Benton County Treasurer's Office oversees property tax collection for the county. In Benton County, the Treasurer mails property taxes on March 6.

Delinquent payments are subject to interest and penalties as recommended by Washington state law.

Property Tax in Benton County: Levies, Exemptions, and Appeals

Benton County property taxes are determined by dividing a parcel’s assessed value by 1,000 and applying the levy rates established by taxing districts.

How the 1 Percent Levy Limit Works

The one percent limit applies to the maximum increase in tax revenue an individual taxing district can levy. It does not apply to individual homes, which tend to increase in assessed valuations at varying rates depending on location and other factors. Taxes on individual homes could increase by more or less than one percent, depending on how their value changes relative to other properties in a district.

Exemptions and Relief

Appealing Your Assessment

Homeowners can appeal to the county's Board of Equalization (BOE). Your appeal must be submitted by July 1st of the current assessment year. If you are filing an appeal due to a change in value, your petition must include a copy of the value notice received from the Assessor. If the Board rejects your appeal, you can take the issue to the Washington State Board of Tax Appeals.

GIS Maps and Parcel Viewer

You can view parcel ownership history and assessment records using the county's interactive maps. For records that predate the online systems, the Washington State Digital Archives holds historical documents.

Foreclosure and Tax Sales

Washington uses two separate processes for foreclosure sales, and it’s important to understand both.

Trustee Foreclosure

This foreclosure process is used when a homeowner becomes delinquent on mortgage payments. After default, the trustee named in the deed of trust can hold a public sale under the Deed of Trust Act without going to court. The sale is advertised in advance, and the process usually moves faster than a court‑based foreclosure.

Judicial Tax Foreclosure

When a homeowner is delinquent for three years, the county may initiate a tax foreclosure. The process usually takes weeks to complete, as tax foreclosures must be filed with the Superior Court. The Benton County Treasurer conducts a tax lien foreclosure auction once every year.

Costs to Access Property Records

Searching online is free. Fees apply when you need a copy or are recording a new document.

How to Record a Document

Washington’s recording act outlines the rules governing the recording of any document that conveys an interest in real estate. The process follows four basic steps:

1. Confirm that your document meets Washington’s requirements under RCW 65.04. That means it needs a cover sheet, signed originals, a notary stamp, a proper legal description, and the right margins and paper size.
2. A Real Estate Excise Tax affidavit must be completed, stating either the sale price or the basis for exemption. In the case of a sale, the Treasurer reviews the affidavit and verifies that all taxes are current prior to recording.
3. Submit to the Auditor in person, by mail, or through an approved e-recording vendor. Pay the recording fee and any excise tax due.
4. After recording, the filer gets the original back. The document is then scanned, indexed, and made available shortly after.
