Clackamas County property tax due dates and installment choices
Oregon’s property tax system gives payment choices. Your discount depends on how much you pay by the first due date. Late interest depends on the installment schedule you chose.
| Payment Choice | Due Timing | Discount | What to Remember |
|---|---|---|---|
| Full payment | By Nov. 15, or next business day if weekend/holiday | 3% discount on current year | Best discount route if you can pay the full bill. |
| Two-thirds payment | 2/3 by Nov. 15; remainder by May 15 | 2% discount on current year | Good middle option if full payment is not possible. |
| One-third installments | 1/3 by Nov. 15; 1/3 by Feb. 15; remainder by May 15 | 0% discount | Cash-flow option, but no discount. |
| Late installment | After installment due date | Discount lost if late | Interest accrues at statutory rate until paid. |
| Unpaid by May 15 | Real property tax becomes delinquent | No discount | Oldest tax year is credited first; foreclosure risk starts after long delinquency. |
Interest rule
Clackamas County lists interest at 16% annually, or 1.333% monthly, until paid. Interest accrues on the 16th of each month.
Foreclosure risk
Real property tax is delinquent if not paid by May 15. Foreclosure proceedings begin when taxes have been delinquent for 3 years.
How to read a Clackamas County property tax bill
The amount you owe is not based only on what your home could sell for. Oregon tax statements use several value terms, and the taxable value can be lower than market value.
RMV
Real Market Value is the assessor’s estimate of what the property would sell for as of January 1 of the current year.
MAV
Maximum Assessed Value is an Oregon Measure 50 value limit. It may increase under certain exception events such as additions or remodels.
AV
Assessed Value is the taxable value. It is the lower of RMV and MAV and is used to calculate taxes.
| Tax Bill Area | What It Means | Practical Action |
|---|---|---|
| Property data | Property address, legal description and account number | Use account number for payment and appeal forms. |
| Mailing address | Where the tax statement goes | If wrong, mark the payment stub or contact the office. |
| Taxing districts | Districts serving the property, including permanent rates and voter-approved taxes | Use this to understand why nearby properties may owe different taxes. |
| Yellow statement | A lender requested information and may pay your tax | Call the lender before paying to avoid duplicate payment. |
| Green statement | No lender requested the information | Pay by Nov. 15 to receive available discount and avoid interest. |
| Asterisk delinquency | Older unpaid taxes may risk foreclosure | Pay oldest years first; county credits payments to oldest tax year due. |
How to appeal Clackamas County property value
A Clackamas County property value appeal is for value, not the tax amount, tax rate or financial hardship. Your evidence should generally reflect property value near January 1 of the assessment year.
PVAB appeal checklist
- 1Wait for tax statement. Appeals to PVAB must be filed after you receive the property tax statement.
- 2Know the deadline. The usual deadline is Dec. 31, or the first working day in January if Dec. 31 falls on a weekend.
- 3Appeal current year only. PVAB appeals are for the current tax year. Prior-year value issues may go to Oregon Tax Court Magistrate Division.
- 4Use county forms. Clackamas County says to use its linked PVAB forms, not generic state forms, because county forms include extra filing information.
- 5Bring value proof. Use comps, appraisal, sales, condition photos, repair estimates, measurement corrections and property-data errors.
