Rate Breakdown

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

How Property Tax Works in Coos County

Property taxes in Coos County are determined by two primary factors: the Assessed Value of the property and the combined millage rate of all taxing districts. The Coos County Assessor determines the Real Market Value (RMV) of your property annually. However, Oregon utilizes a unique assessment system where the Assessed Value is often lower than the RMV due to state laws that limit the growth of assessed values.

Millage rates represent the tax rate per $1,000 of assessed value. Your total tax bill is the sum of millages from various entities, including the county, city government, school districts, and special service districts (such as fire or water). To calculate your estimated tax, multiply your Assessed Value by the total millage rate and divide by 1,000.

Available Exemptions

Oregon offers several programs to reduce the tax burden for eligible homeowners. These exemptions can significantly lower your annual payments:

• Homeowner Property Tax Exemption: Available to senior citizens (60+) and individuals with disabilities who meet specific income requirements.
• Disabled Veterans Exemption: Provides significant property tax relief for veterans with a service-connected disability.
• Agricultural Deferrals: Certain farm properties may qualify for special assessment status, lowering the taxable value of the land.

To apply for these exemptions, property owners must file an application with the Coos County Assessor's office by the state-mandated deadlines.

Payment Schedule & Deadlines

Property taxes in Coos County are billed annually, but payments are typically split into two installments to make the cost more manageable:

• First Installment: Due November 15th.
• Second Installment: Due March 15th.

Payments can be made in person at the County Treasurer's office or via mail. It is critical to adhere to these dates; payments received after the deadline are subject to a penalty. Failure to pay taxes over a prolonged period may eventually lead to a tax foreclosure action.

Appealing Your Assessment

If you believe the Assessor's office has incorrectly valued your property, you have the right to appeal. The process typically begins with an informal review with the Coos County Assessor to ensure all data is accurate.

If a resolution is not reached, you may file a formal appeal with the Board of Property Tax Appeals (BOPTA). This must be done within a specific window—usually 30 days after the notice of assessment is mailed. You will be required to provide evidence, such as recent comparable sales or a professional appraisal, to support your claim for a lower valuation.
