How Property Tax Works

Coos County, Oregon operates on a property tax system that serves as the primary funding mechanism for essential local services including schools, fire protection, law enforcement, libraries, and county operations. Property owners receive their annual tax bills on or before October 25th each year, with taxes calculated based on the assessed value of their property multiplied by the applicable tax rate for their specific location.

The effective property tax rate in Coos County varies significantly by location within the county due to different combinations of special taxing districts, school districts, fire districts, and other local service areas. While the base county rate provides a foundation, property owners may also pay additional assessments for school bonds, urban renewal districts, library districts, and other special services depending on where their property is located. This district-based system means that two similar properties in different areas of Coos County can have substantially different tax obligations.

Section 4

Supplemental Tax Bills

Supplemental taxes in Coos County are triggered by changes in property ownership, new construction, or property improvements that increase assessed value during the tax year. When these events occur, the county assessor calculates additional taxes based on the increased assessment value prorated for the remaining portion of the tax year.

For example, if a property owner completes a $100,000 home addition in January, and their effective tax rate is 1.2%, they would owe approximately $1,200 in supplemental taxes for that improvement ($100,000 × 0.012). This supplemental bill would be issued separately from the regular annual tax bill and would have its own payment due dates, typically allowing 30 days from the date of billing for payment.

Escrow & Property Taxes

Most mortgage lenders in Coos County require property tax escrow accounts for borrowers, collecting monthly payments along with principal and interest to ensure tax obligations are met. Lenders typically collect 1/12th of the annual tax bill each month, plus an additional cushion amount as allowed by federal regulations.

Given Coos County's three-installment payment schedule (November 15, February 15, and May 15), lenders must carefully manage escrow accounts to ensure sufficient funds are available for each payment deadline. Property owners should verify that their lender has current tax bill information, as assessment changes or tax rate adjustments can affect required escrow payments. The county provides online access to current tax information that borrowers can share with their lenders to ensure accurate escrow calculations throughout the year.

Frequently Asked Questions

Q: When are property taxes due in Coos County for FY 2025-2026? A: Property taxes are due in three installments: November 15, 2025; February 15, 2026; and May 15, 2026. If the due date falls on a weekend, the deadline extends to the next business day.

Q: What tax credits are available and do they require application? A: Coos County may offer homestead tax credits up to $250,000 of assessed value by ordinance or resolution. All tax credits require separate application and are NOT automatically applied. Applications must be submitted before April 1st with a $250 filing fee.

Q: How does the Homestead Credit work? A: The Homestead Credit caps assessment increases rather than reducing market value. It requires annual filing and helps limit year-over-year assessment growth on qualifying primary residences. This is a tax credit that reduces your tax bill, not an exemption that reduces assessed value.

Q: When are properties assessed in Coos County? A: Property assessments are conducted annually with values established as of January 1st for the following tax year. Assessment notices are typically mailed in spring, with appeal deadlines clearly stated on the notice.

Q: What are the penalties for late payment? A: Oregon law provides for interest and penalties on delinquent property taxes. Specific penalty rates and collection procedures are established by state statute and county policy.

Q: Can I pay my property taxes online? A: Yes, Coos County provides online payment options through their tax office website. Check the official Coos County Tax Office website for current payment portal access and accepted payment methods.

Q: Why do tax rates vary within Coos County? A: Tax rates vary because properties are served by different combinations of school districts, fire districts, library districts, and special service districts. Each district adds its own tax rate component to fund local services.

Q: How do I appeal my property assessment? A: Assessment appeals must be filed within the deadline specified on your assessment notice, typically in late spring or early summer. Contact the Coos County Assessor's office for specific appeal procedures and required documentation.
