Who sends the property tax bill in Clackamas County, and how do you pay it?
The bill comes from the Clackamas County Assessment and Taxation (County Assessor and Tax Collector). The value it is based on is set by a separate office, the Clackamas County Assessor's Office (Assessment and Taxation), which is who to ask if the value looks wrong. For how to look up and pay the bill, go to the county's own payment information.
One office both values the property and collects the tax: the County Assessor is also the Tax Collector. Its public hours are Monday through Thursday. Oregon's tax year starts July 1 and the 2026-27 statements were not out when this was checked; owners signed up for the county's paperless eNotices can see theirs as early as October 20. The November 15, February 15 and May 15 schedule and the 3% and 2% discounts are set by state law (ORS 311.505) for every county. If the statement arrives late, state law (ORS 311.507) keeps the discount open until 15 business days after it was mailed, if that is later than November 15. A yellow statement means a lender asked for the bill and may pay it; check with your lender if you are unsure. Online payments carry a convenience fee charged by the county's payment provider, US Bank ($3 for an e-check, 2.49% for a credit card). The county's exemption and deferral programs (senior and disabled deferral, disabled veteran exemption) are state programs.
When are property taxes due in Clackamas County?
For the 2026-27 bill, Clackamas County splits the bill into 3 payments, the first due November 15, 2026 and the last May 15, 2027. Interest is 1 1/3% a month (16% a year) on an unpaid installment until paid. Under state law it starts on December 16 for the first third, a month after the due date, and on February 16 and May 16 for the second and third. Mailed payments count if postmarked by the due date; bank bill-pay payments count only when they reach the office. Real property taxes still unpaid after May 15 are delinquent, and foreclosure begins once taxes have been delinquent for three years.
| Payment | Due | Note |
|---|---|---|
| First third, or full or two-thirds payment for a discount | November 15, 2026 | Pay the full year by this date for a 3% discount, or two-thirds for a 2% discount; paying one-third earns no discount. November 15, 2026 is a Sunday. The county says a due date that falls on a weekend or legal holiday is extended through the next business day, so a payment made Monday, November 16, 2026 is on time. |
| Second third | February 15, 2027 | Only if paying in thirds. February 15, 2027 is Presidents Day, a legal holiday under Oregon law (ORS 187.010), so under the county's next-business-day rule a payment made Tuesday, February 16, 2027 is on time. |
| Third third | May 15, 2027 | Due for anyone paying in thirds, and for anyone who paid two-thirds in November. May 15, 2027 is a Saturday, so under the county's next-business-day rule a payment made Monday, May 17, 2027 is on time. |
