What you'll pay, at a glance

Property taxes are the largest local tax most homeowners pay. The effective rate measures the real tax bill as a share of home value — a more useful number than the nominal “mill rate,” because assessment practices vary county to county.

How this is calculated

The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.

About Bonner County, ID

Buying a home in Bonner County means weighing a higher-than-average price against a lighter tax bill. The median home value here sits at $487,900, and the resulting annual property tax of $1,847 works out to an effective rate of 0.379 percent — noticeably under Idaho's statewide figure of 0.446 percent and far beneath the national median of 0.794 percent. Among Idaho's 44 counties, this one ranks 33rd for property tax rate, so the tax side of ownership is comparatively gentle even though the purchase price is steep. Households earning the median income of $66,979 would devote a modest slice of that to real-estate taxes each year. Communities such as Blanchard, Careywood, and Clark Fork share this tax structure, giving buyers across the county a similar picture: pay more upfront, then face smaller recurring tax costs than many other places.

Frequently asked questions

What is the property tax rate in Bonner County, ID?
The effective rate is 0.38% — meaning the median tax bill equals about 0.38% of the median home value.
How much are property taxes on a median home?
On the median home ($487,900), the estimated annual bill is about $1,847.
Is Bonner County's rate high or low?
Compare it to the state median of 0.45% and the national average near 1.1%.
How does the effective rate differ from my mill rate?
A mill rate is the nominal levy per $1,000 of assessed value. The effective rate reflects what you actually pay after exemptions and assessments — it's the median tax bill as a share of median home value, so it better predicts your real cost.
Will a reassessment raise my tax bill?
Not necessarily. If your home's assessed value rises, your bill can go up, but only if the mill rate and exemptions stay flat. Contact the Bonner County assessor's office to review your current assessment.
Can I appeal my property tax assessment?
Yes. Most counties allow an appeal when you believe the assessed value exceeds the market value. File with the Bonner County assessor within the local deadline, typically with comparable sales as evidence.
