How Property Tax Works

Marion County's property tax system is the primary funding mechanism for essential local services including schools, public safety, roads, parks, and county operations. Property taxes are calculated based on your property's assessed value multiplied by the applicable tax rate, which varies significantly depending on your specific location within the county due to overlapping special taxing districts such as school districts, urban renewal areas, fire districts, and water authorities.

The effective tax rate in Marion County typically ranges from approximately $15 to $25 per $1,000 of assessed value, with the city of Salem area showing rates around $20.54 per $100 of valuation for the 2025 tax year. Your actual rate depends on which combination of taxing districts serve your property. Marion County follows Oregon's unique property tax system where assessed value increases are constitutionally limited, but voters can approve additional levies and bonds that affect your total tax bill.

Supplemental Tax Bills

Supplemental taxes are additional property tax bills issued when there are changes to your property that affect its assessed value during the tax year. The most common triggers include new construction completion, major improvements or additions, and changes in property ownership that may affect exemption eligibility. Unlike some states, Oregon generally does not reassess property to current market value upon sale due to constitutional assessment limitations.

When supplemental taxes are triggered, they are calculated by applying the applicable tax rate to the difference between the old and new assessed values, prorated for the portion of the tax year remaining. For example, if you complete a $50,000 home addition in January and your tax rate is $20 per $1,000, you would owe approximately $1,000 in supplemental taxes ($50,000 × 0.020) for that tax year. Supplemental tax bills are typically mailed within 60-90 days of the triggering event and have their own due dates separate from regular property tax bills.

Escrow & Property Taxes

Most mortgage lenders require property tax escrow accounts to ensure timely payment of property taxes. Your lender collects 1/12 of your estimated annual property tax bill with each monthly mortgage payment, depositing these funds into an escrow account. Marion County mails approximately 124,000 property tax statements annually, and lenders typically receive and pay these bills directly on your behalf.

Marion County offers a 3% discount for full payment by November 15th, but most lenders pay according to the installment schedule to manage cash flow: two-thirds payment by November 15th (with 2% discount on amount paid), and the remaining one-third by May 15th of the following year. Lenders must provide you with annual escrow account statements showing deposits, payments, and any surplus or shortage. If you believe your escrow payment is incorrect, contact your lender with your current Marion County tax statement to request an escrow analysis and adjustment.

Frequently Asked Questions

Q: When are property taxes due for the 2025-2026 tax year? A: Full payment is due November 15, 2025 (3% discount). Alternatively, pay two-thirds by November 15, 2025 (2% discount on amount paid) and one-third by May 15, 2026.

Q: What tax credits are available and do I need to apply? A: Major credits include Homestead ($29,000 credit for seniors/disabled), Disabled Veterans ($58,000 for 100% service-connected disability), and Surviving Spouse of Public Safety Officers ($250,000). ALL credits require separate application through the Marion County Assessor's office and are not automatic.

Q: How does the Homestead credit work? A: The Homestead credit provides up to $29,000 off your assessed value for qualified seniors (62+) or permanently disabled property owners. You must apply annually through the County Assessor's office. This is a tax credit that reduces your taxable assessed value, not a cap on assessment increases.

Q: How often are properties reassessed? A: Oregon law requires annual assessment, but increases are constitutionally limited to 3% per year maximum. Properties are physically inspected on a rotating cycle, typically every 5-6 years, unless there are improvements or other changes.

Q: What are the penalties for late payment? A: Interest accrues at 1.33% per month (16% annually) on unpaid taxes after the due date. Additional penalties may apply for severely delinquent accounts, and properties can eventually be foreclosed for unpaid taxes.

Q: Can I pay property taxes online? A: Yes, visit www.co.marion.or.us/AO/TAX or call (877) 254-7870. Online payments, mail payments to Marion County Tax Collector, PO Box 2511, Salem, OR 97308, or pay in person at the Marion County offices.

Q: Why did my tax bill increase if my assessed value only went up 3%? A: While assessed value increases are capped at 3%, your total tax bill can increase due to voter-approved bonds, levies, and new special district assessments. These additional taxes are not subject to the 3% cap.

Q: How do I appeal my property assessment? A: File an appeal with the Marion County Board of Property Tax Appeals by December 31st of the tax year. Contact the Marion County Assessor at (503) 588-5036 for appeal forms and procedures.
