The median real estate tax bill in St. Croix County, Wisconsin is $4,297 per year, and the median home is worth $349,700. Both figures are the US Census Bureau's survey medians for owner-occupied households (US Census Bureau, American Community Survey (ACS) 5-year estimates, 2023).
What the St. Croix County numbers mean
A median is the middle household: half of owner-occupied households in St. Croix County pay more than $4,297, and half pay less. Your own bill is set by your home's assessed value, the exemptions you qualify for, and the local taxing districts your property sits in — so individual bills vary widely around the median.
Dividing the median tax by the median home value gives a derived effective rate of 1.23% for St. Croix County. It is an estimate built from two survey medians, not the county's official rate, but it is a fair way to compare the local tax burden with other counties where home values are very different.
