Property Tax in Marion County, Oregon
The median real estate tax bill in Marion County, Oregon is $3,382 per year, and the median home is worth $383,300. Both figures are the US Census Bureau's survey medians for owner-occupied households (US Census Bureau, American Community Survey (ACS) 5-year estimates, 2023).
What the Marion County numbers mean
A median is the middle household: half of owner-occupied households in Marion County pay more than $3,382, and half pay less. Your own bill is set by your home's assessed value, the exemptions you qualify for, and the local taxing districts your property sits in — so individual bills vary widely around the median.
Dividing the median tax by the median home value gives a derived effective rate of 0.88% for Marion County. It is an estimate built from two survey medians, not the county's official rate, but it is a fair way to compare the local tax burden with other counties where home values are very different.

How the tax is worked out
The bill is built in stages. First the assessor puts a market value on the property. Exemptions — a homestead exemption above all — then reduce the taxable amount. Finally the combined local rate is applied. To see the scale: at the county's derived rate of 0.88%, each $100,000 of value corresponds to about $882 of tax a year, and a $400,000 home to roughly $3,528. Real bills use the official assessment and district rates, not this derived figure, so treat the example as a sense of scale only.
Checking your assessment in Marion County
Most successful appeals are won on facts, not arguments. Start with the property record card held by the Marion County assessor: wrong square footage, an extra room, or a missing homestead exemption are common and fixable. Next, line your assessed value up against recent sales of genuinely similar homes nearby. Many disputes end at an informal conversation with the assessor's office; if yours does not, file the formal appeal with the review board named on your notice before its deadline, evidence attached, and keep paying the bill in the meantime so penalties do not build up.
