Okanogan County Overview
Okanogan County Assessor Property Tax Records
The Okanogan County Assessor's Office is the primary source for property valuation data and tax records in the county. Assessor Larry Gilman heads the office, which is located at 149 3rd North, Room 202, Okanogan, WA 98840. The mailing address is P.O. Box 152, Okanogan, WA 98840. You can reach the office by phone at 509-422-7190. Hours are Monday through Friday, 8 AM to 4:30 PM, except holidays. Staff welcome questions about how property is assessed and are available to speak to community groups about the process.
The Assessor's primary role is to establish fair market value for all property in Okanogan County for tax purposes. State law requires that values be equitable, fair, and uniform across all property owners. Taxable property is divided into real property, which includes land, buildings, and mobile homes, and personal property, which includes machinery, equipment, and business fixtures. Household goods and personal effects are exempt from taxation. Visit the Okanogan County Assessor page for full details and contact information.

Search Okanogan County Property Tax Records Online
Okanogan County provides two main tools for online property research. The first is the county's property search portal, which serves as the central gateway for property lookups. From there, users are directed to either MapGeo for interactive mapping or TaxSifter for tabular property tax data. The page also links to Department of Revenue brochures, school district contact information, and Change of Value update flyers.
The Okanogan County TaxSifter portal is the county's property tax search system, powered by TerraScan through PublicAccessNow. It is intended for property tax purposes only. Manifest errors are unintentional and subject to correction. Contact the Assessor at 509-422-7190 or assessor@co.okanogan.wa.us, or the Treasurer at 509-422-7180 or treasurer@co.okanogan.wa.us, to report any data errors you find. Users agree not to use any data lists for commercial purposes under RCW 42.17.260(9).

Okanogan County TaxSifter Property Search
TaxSifter at okanoganwa-taxsifter.publicaccessnow.com lets you search Okanogan County property tax records by parcel number, owner name, or address. No account is needed. Results show property characteristics, current and prior assessed values, tax amounts, and ownership details. The county disclaims liability for any loss or damages from use, misuse, or modification of the data. Users agree to hold Okanogan County harmless for any issues arising from inaccuracies or gaps in the data.
The system was partially funded by contributions from businesses and individuals in the county. Information is subject to change without notice and does not represent a commitment by the county for future data availability. For best results, use the parcel number if you know it. If not, searching by street address usually returns the right property quickly in this rural county.

Note: RCW 42.17.260(9) prohibits using data from this system to create lists of individuals for commercial contact purposes. Misuse of public records can result in penalties under state law.
Okanogan County MapGeo Interactive Mapping
Okanogan County replaced its previous MapSifter mapping tool with MapGeo, a more robust interactive platform. The MapGeo tool supports quick searches by street address, owner name, and property ID. Advanced search options let you filter by multiple variables including date of sale, building value, and sanitary source type. Users can select abutting properties and generate mailing lists with distance buffers, which is useful for neighborhood notifications and planning research.
Google Street View is integrated directly into the MapGeo platform, so you can view the property without leaving the map interface. Map controls include zoom buttons, scroll-wheel zoom, two-finger mobile zoom, and shift-drag rectangle zoom for desktop users. The main menu gives access to a start tour, contact form, dashboard, and account settings. Feedback can be submitted through the chat bubble icon or by emailing mapgeosupport@mapgeo.io. Spatial data in MapGeo is for reference only; accuracy should be confirmed for legal transactions.
Okanogan County Property Tax Assessment
Washington State law under RCW 84.40 requires all property to be valued at 100% of fair market value. The Okanogan County Assessor applies this standard to all taxable real and personal property in the county. Fair market value is what a willing buyer would pay a willing seller in an open market transaction. The Assessor must ensure values are equitable and uniform, meaning similar properties pay similar taxes.
The amount of tax on any given parcel equals the assessed value multiplied by the combined levy rate for all taxing districts covering that parcel. Different parts of Okanogan County fall under different combinations of school districts, fire districts, and other local taxing authorities, so levy rates vary by location. Business personal property, including machinery and equipment, must be reported to the Assessor each year by April 30. The Assessor values it based on depreciated cost.
Paying Okanogan County Property Taxes
The Okanogan County Treasurer handles all property tax billing and collection. The Treasurer's Office is also located in Okanogan and can be reached at 509-422-7180 or treasurer@co.okanogan.wa.us. Under RCW 84.56, if your total tax bill is more than $50, you may pay in two halves. The first half is due April 30. The second half is due October 31. If the bill is $50 or less, full payment is due April 30.
Missing a due date triggers interest and penalties under the same statute. These accrue monthly and continue until the full balance is paid. If taxes remain unpaid for three years, the Treasurer may begin foreclosure proceedings under RCW 84.64. Contact the Treasurer at 509-422-7180 to get a current payoff amount before submitting a late payment. The Washington Department of Revenue maintains a directory of all county assessor and treasurer contacts at propertytax.dor.wa.gov/county-contacts if you need to verify any contact details.
Okanogan County Property Tax Exemptions
Okanogan County property owners may qualify for state-administered exemption programs. The most common is the senior citizen and disabled persons exemption, which reduces the assessed value used to calculate taxes for qualifying homeowners. You must own and occupy your home as your primary residence and meet the income limit set by the state for the current tax year.
Other programs cover agricultural land under current-use assessment, open space, and forest land. These programs assess eligible properties at a lower use-based value rather than full market value. The Washington Department of Revenue lists all current programs and income limits on the DOR exemptions and deferrals page. Apply through the Okanogan County Assessor's Office at 149 3rd North, Room 202. Call 509-422-7190 for current income thresholds and required documents.
Appealing an Okanogan County Property Tax Value
If you believe your assessed value is too high, contact the Assessor's Office at 509-422-7190. Ask how the value was set and review the property record for errors. Mistakes in square footage, bedroom count, or other physical attributes can sometimes be corrected without a formal appeal. The Assessor's staff welcome these conversations and are available to explain how values are determined.
If a discussion with the Assessor does not resolve the issue, file a formal appeal with the Okanogan County Board of Equalization before the deadline on your Notice of Value. Bring evidence such as comparable sales of similar properties nearby. If the Board's decision does not satisfy you, appeal next to the Washington State Board of Tax Appeals. That board reviews county-level decisions for all 39 Washington counties.
Note: You can only appeal the assessed value shown on your parcel. The levy rate and individual district budgets are set separately and are not subject to appeal through the Board of Equalization.
