Good to know
What is the property tax rate in Coos County?
The effective rate is about 1.89%. The median homeowner pays $3,579 a year on a home worth a median $188,900 (ACS 2020–2024). The legal tax rates set by each taxing unit are different numbers; the effective rate is what owners actually pay as a share of value.
How much is property tax on a $200,000 home in Coos County?
About $3,780 a year, or roughly $315 a month, at Coos County's average effective rate of 1.89%. Homestead, senior, veteran or other exemptions can lower the real bill, and a recent purchase or reassessment can raise it.
Why is my bill different from this estimate?
Your bill depends on your home's assessed value from the town assessor, the exact taxing units where you live (county, city, school district, special districts) and any exemptions you get. These figures are medians across all owner-occupied homes, not a bill for any address.
How current is this data?
It comes from the U.S. Census Bureau's American Community Survey 5-year estimates for 2020–2024, the latest release. Homeowners report the taxes they paid, so the numbers lag current bills by one to two years. We update the site when the Census Bureau publishes new estimates each December.
