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 St. Croix County, WI

Buying a home in St. Croix County means weighing a higher price tag against a gentler tax rate. The median home value here sits at $377,700, and the annual property tax bill that comes with it averages $4,420, based on an effective rate of 1.170%. That rate lands below Wisconsin's statewide median of 1.362%, and within the state this county ranks 58th of 72 counties, so the tax side of the equation is comparatively favorable. Households earn a median of $103,046, with per-capita income at $50,302, which helps offset the cost of ownership. Hudson, the largest of the area's communities, anchors a county where buyers should expect to pay more upfront for a home but face a lighter annual tax obligation than many Wisconsin counties. Nationally, the median effective rate is 0.794%, so property taxes here remain above that benchmark.

Frequently asked questions

What is the property tax rate in St. Croix County, WI?
The effective rate is 1.17% — meaning the median tax bill equals about 1.17% of the median home value.
How much are property taxes on a median home?
On the median home ($377,700), the estimated annual bill is about $4,420.
Is St. Croix County's rate high or low?
Compare it to the state median of 1.36% 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 St. Croix 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 St. Croix County assessor within the local deadline, typically with comparable sales as evidence.
