Rate Breakdown

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

How Property Tax Works in Jefferson County

Property taxes in Jefferson County are based on the assessed value of your property and the applicable tax rates (millage rates). Here's how the process works:

• Assessment: The Jefferson County Assessor's Office determines the fair market value of your property as of January 1 each year. This value is used to calculate your tax liability.
• Tax Rates: Tax rates are set by local taxing districts (e.g., schools, fire departments, county government) and are expressed in "mills" (1 mill = $1 per $1,000 of assessed value). The total millage rate is applied to your assessed value to determine your annual tax bill.
• Tax Calculation: Your tax bill = (Assessed Value ÷ 1,000) × Total Millage Rate. New construction or major improvements may trigger reassessment.

Available Exemptions

Jefferson County offers several exemptions that may reduce your property tax burden:

• Senior Citizen/Disabled Exemption: Homeowners aged 61+ or with disabilities may qualify for a reduction in assessed value if they meet income requirements.
• Veteran Exemption: Disabled veterans or their surviving spouses may be eligible for partial or full exemptions based on disability rating.
• Homestead Exemption: While Washington does not have a traditional homestead exemption, the state limits annual property tax increases to 1% for primary residences under certain conditions.

Applications for exemptions must be filed with the Jefferson County Assessor's Office by March 31.

Payment Schedule & Deadlines

Jefferson County property taxes are due in two installments:

• First Half: Due by April 30 (or next business day if weekends/holidays apply).
• Second Half: Due by October 31.

Payment options include online, mail, or in-person at the Jefferson County Treasurer's Office. Late payments incur penalties:

• 1-30 days late: 3% penalty.
• 31+ days late: Additional 8% penalty (total 11%).
• After one year: Delinquent accounts may face tax foreclosure.

Appealing Your Assessment

If you believe your property is overassessed, you can appeal to the Jefferson County Board of Equalization:

• Deadline: Appeals must be filed by July 1 of the assessment year (or within 60 days of the assessment notice, whichever is later).
• Process: Submit evidence (e.g., recent comparable sales, appraisal reports) proving your property's value is incorrect. The Board will review and issue a decision.
• Further Appeals: If unsatisfied, you may appeal to the Washington State Board of Tax Appeals or Superior Court.
