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 Keweenaw County, MI

Keweenaw County’s effective property tax rate of 0.995% sits below Michigan’s statewide median of 1.087%, placing it 57th among the state’s 83 counties. Against the national median of 0.794%, however, this Upper Peninsula county runs higher. The gap matters because property values here are lower than many parts of the country: a median home worth $169,800 generates an annual tax bill of about $1,689. Household income in Keweenaw County averages $52,583, while per-capita income reaches $45,090. Communities such as Ahmeek, Copper Harbor, and Mohawk anchor this sparsely populated county, where the tax rate reflects a mix of local levies and a limited commercial base. Compared with Michigan overall, homeowners here pay a slightly smaller share of value in taxes, though the national picture shows the county’s rate is not especially cheap by broader standards.

Frequently asked questions

What is the property tax rate in Keweenaw County, MI?
The effective rate is 0.99% — meaning the median tax bill equals about 0.99% of the median home value.
How much are property taxes on a median home?
On the median home ($169,800), the estimated annual bill is about $1,689.
Is Keweenaw County's rate high or low?

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 Keweenaw 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 Keweenaw County assessor within the local deadline, typically with comparable sales as evidence.
