Rate Breakdown

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

How Property Tax Works in Umatilla County

Property taxes in Umatilla County are determined by a combination of the property's Assessed Value (AV) and the applicable millage rates. The County Assessor determines the value of your property, which is then adjusted based on Oregon's state laws to determine the assessed value. This value is not necessarily the same as the market value.

The total tax burden is calculated using millage rates. One mill represents one-tenth of a cent per dollar of assessed value. These rates are set annually by various local taxing districts, including the county, city governments, school districts, and special service districts. To calculate your estimated tax, multiply your property's assessed value by the total millage rate and divide by 1,000.

Available Exemptions

Oregon offers several programs to reduce the tax burden for qualifying homeowners. While these may not eliminate taxes entirely, they can provide significant relief:

• Homeowner Property Tax Deferral: Available to senior citizens (60+) and disabled individuals, allowing them to defer the payment of property taxes until the property is sold or the owner passes away.
• Disabled Veterans Exemption: Veterans with a service-connected disability may qualify for a partial or full exemption from property taxes.
• Agricultural Deferral: Land used primarily for farming or forestry may be assessed at a lower value based on its productivity rather than its market value.

Payment Schedule & Deadlines

In Umatilla County, property taxes are typically billed annually, though they are split into two primary installments to make payments more manageable:

• First Installment: Generally due by November 15th.
• Second Installment: Generally due by April 15th.

It is critical to meet these deadlines to avoid penalties. Late payments will accrue interest and penalties as mandated by state law. If you are unable to pay in full, it is recommended to contact the Umatilla County Treasurer's office immediately to discuss available options or payment arrangements.

Appealing Your Assessment

If you believe your property has been overvalued or that there is an error in your assessment, you have the right to appeal. The process typically begins with a request for a review from the County Assessor's office.

If the internal review does not resolve the issue, you may file a formal appeal with the Board of Property Tax Appeals (BOPTA). Appeals must be filed within a specific window—usually by September 15th of the year preceding the tax year in question. You will be required to provide evidence, such as recent comparable sales or independent appraisals, to support your claim for a lower valuation.
