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 Canyon County, ID

Canyon County’s effective property tax rate of 0.516% sits above Idaho’s statewide median of 0.446%, placing it 12th among the state’s 44 counties. That ranking signals a heavier property tax load than most Idaho counties carry. On a median home value of $390,000, the median annual bill comes to $2,011, set against a median household income of $76,488 and per-capita income of $32,651. Compared with the national median effective rate of 0.794%, however, Canyon County homeowners pay a considerably lower share of value than the average American. Nampa, the largest city in the county, anchors much of this housing stock. The picture that emerges is a county that taxes property more aggressively than its own state but still well below national norms, a split that shapes how affordability looks depending on whether you measure locally or across the country.

Frequently asked questions

What is the property tax rate in Canyon County, ID?
The effective rate is 0.52% — meaning the median tax bill equals about 0.52% of the median home value.
How much are property taxes on a median home?
On the median home ($390,000), the estimated annual bill is about $2,011.
Is Canyon 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 Canyon 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 Canyon County assessor within the local deadline, typically with comparable sales as evidence.
