Rate Breakdown

Property taxes in Walla Walla County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Walla Walla County

Property taxes in Walla Walla County are based on the assessed value of your property and the combined millage (tax) rates set by local taxing districts. The County Assessor's Office determines your property's assessed value annually, which is typically close to its market value. This value is then multiplied by the total tax rate (expressed in dollars per $1,000 of assessed value) to calculate your tax bill.

• Assessment Process: Properties are revalued every year, with physical inspections conducted at least once every six years.
• Tax Rates: Rates vary depending on your location and the services provided (e.g., schools, fire districts, city/county budgets).
• Example Calculation: A home valued at $300,000 with a combined rate of $10 per $1,000 would owe $3,000 annually.

Available Exemptions

Washington State and Walla Walla County offer several exemptions to reduce property tax burdens for eligible residents:

• Senior Citizen/Disabled Exemption: Low-income seniors (61+) or disabled individuals may qualify for a reduction in assessed value.
• Veteran Exemption: Veterans with a service-connected disability of 100% may be eligible for full exemption.
• Homestead Exemption: While Washington doesn’t have a traditional homestead exemption, the Senior Citizen Tax Deferral Program allows qualifying seniors to defer payments.

Applications for exemptions must be submitted to the Walla Walla County Assessor’s Office with supporting documentation.

Payment Schedule & Deadlines

Property taxes in Walla Walla County are due in two installments:

• First Half: Due by April 30.
• Second Half: Due by October 31.

Payments made after the deadline incur a 1% monthly interest penalty (up to 12% maximum). If taxes remain unpaid for three years, the county may initiate foreclosure proceedings. Payment options include:

• Online (credit/debit card or e-check, fees may apply).
• Mail or in-person at the Treasurer’s Office.
• Partial payments are accepted but must cover at least one full installment to avoid penalties.

Appealing Your Assessment

If you believe your property’s assessed value is incorrect, you can appeal to the Walla Walla County Board of Equalization:

• Deadline: Appeals must be filed within 60 days of the assessment notice (typically mailed in July).
• Process: Submit a written appeal with evidence (e.g., recent appraisals, comparable sales) to support your claim.
• Hearing: The Board will review your case and may adjust the valuation if justified.

For complex disputes, consulting a property tax professional is recommended. Contact the Assessor’s Office for detailed instructions and forms.
