Rate Breakdown

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

How Property Tax Works in Columbia County

Property taxes in Columbia County are based on the assessed value of your property, determined by the County Assessor's Office. Assessments are conducted annually, reflecting the fair market value as of January 1. The taxable value is calculated by applying the county's millage rate (tax rate per $1,000 of assessed value) to your property's assessed value. Columbia County's millage rate includes levies from multiple taxing districts, such as schools, fire departments, and local governments.

• Assessment Process: The Assessor evaluates property values using market trends, property characteristics, and recent sales data.
• Millage Rates: Rates vary by location and are set annually by taxing authorities. Your tax bill combines these rates into a single levy.

Available Exemptions

Washington State and Columbia County offer several property tax exemptions to eligible homeowners:

• Senior Citizen/Disabled Exemption: Low-income seniors (61+) or disabled individuals may qualify for reduced property taxes or deferrals.
• Veteran Exemption: Veterans with a service-connected disability may receive partial exemptions based on disability rating.
• Homestead Exemption: While Washington doesn't offer a traditional homestead exemption, other programs like the "Senior Property Tax Relief Program" provide similar benefits.

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

Payment Schedule & Deadlines

Columbia County property taxes are due in two installments:

• First Half: Due by April 30.

Appealing Your Assessment

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

• Deadline: Appeals must be filed within 30 days of the assessment notice (typically mailed in July).
• Process: Submit evidence (e.g., recent appraisals, comparable sales) to support your claim. A hearing will be scheduled.
• Outcome: The board may adjust your assessment, which could lower your tax bill.
