Clackamas County Property Tax Rates: How Oregon Tax Bills Are Calculated
Oregon property tax is different from a simple market-value percentage. Your tax bill depends on real market value, maximum assessed value, assessed value, local district rates, constitutional limits and any account-specific charges.
Real Market Value
RMV is the county’s estimate of what the property would sell for as of the assessment date.
Maximum Assessed Value
MAV is an Oregon-specific value limit that usually grows under Measure 50 rules unless exceptions apply.
Assessed Value
Assessed value is generally the lower of RMV and MAV, and it is the base used for most tax-rate calculations.
| Calculation Piece | Meaning | Where to Verify |
|---|---|---|
| Real Market Value | Estimated market value for the property. | County assessment record / tax statement. |
| Maximum Assessed Value | Oregon Measure 50 value limit used in assessment. | Oregon DOR property tax resources. |
| Assessed Value | Usually the lower of RMV and MAV. | Official tax statement and county assessment record. |
| Tax rate | Local rate usually expressed per $1,000 of assessed value. | Tax statement and local taxing district details. |
| Special items | Local bonds, levies, fees or account-specific charges can affect final amount. | Tax statement line items and county office. |
1
Find RMV, MAV and assessed value
Do not estimate from market value alone.
▾
Use your Clackamas County tax statement or official county assessment record from Assessment & Taxation. Oregon taxes often use assessed value, not the full real market value.
2
Use the combined rate for your location
Rates differ by city, school, fire, library and other districts.
▾
Clackamas County properties in Oregon City, Lake Oswego, Milwaukie, Happy Valley, Wilsonville, West Linn or rural areas can have different taxing districts. Use the rate shown on your actual statement, not a generic county average.

▾
After estimating, return to Clackamas County Assessment & Taxation to confirm the actual balance, discounts, installments, interest or account-specific details.
What to Do If Your Clackamas County Property Tax Bill Looks Too High
A high bill can come from higher assessed value, tax-rate changes, new construction, changed taxing districts, missing exemptions, special assessments, prior unpaid amounts, or a misunderstanding of Oregon’s RMV/MAV system.
Check value first
Compare RMV, MAV and assessed value. A high RMV does not always mean your taxable assessed value rose the same amount.
Check exemptions/deferrals
Senior or disabled deferral is handled under Oregon rules. Confirm eligibility before deadlines.
Check appeal timing
Oregon property value appeal windows can be strict. Do not wait until taxes are delinquent to question value.
| Reason Bill Increased | What It Means | Best Place to Check |
|---|---|---|
| Assessed value changed | MAV/RMV or exception rules may have changed the assessed value. | County assessment record |
| Tax rate changed | Local district rates, bonds or levies may have changed. | Current tax statement line items. |
| New construction | Improvements can affect value under Oregon assessment rules. | Assessment details and county office. |
| Deferral or exemption issue | Program status or application may need review. | Oregon deferral resources |
| Late or prior balance | Unpaid prior amounts or interest may increase amount due. | County tax account / statement. |

Clackamas County Property Tax Tips That Prevent Missed Discounts, Wrong Payments and Appeal Delays
These tips help homeowners, new buyers, escrow users, seniors, disabled homeowners, landlords and out-of-state owners avoid common Clackamas County property tax mistakes.
Pay early if you want the discount
The common Oregon full-payment discount is tied to timely payment. Do not wait until November 15 to solve account or payment problems.
Do not estimate from market value alone
Oregon’s assessed value may be lower than real market value because of the MAV system. Use assessed value for tax estimates.
Escrow owners should still verify payment
If your lender pays taxes, check that payment posted to the correct tax account before interest or delinquency issues begin.
Review RMV, MAV and AV together
A rise in real market value does not always mean the same rise in assessed value. Compare all three lines before disputing.
Check deferral deadlines early
Senior and disabled deferral programs require eligibility review and documents. Start before payment deadlines create pressure.
Save receipts and statements
Keep your statement, confirmation number, payment method and date. This helps solve duplicate payment, escrow and posting questions.
