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 Washington County, MN

Washington County’s effective property tax rate of 0.987% edges just above Minnesota’s statewide median of 0.985%, a gap so narrow it barely separates the county from the state’s middle ground. Against the national median of 0.794%, however, the county sits noticeably higher. Its rank of 42nd out of 87 Minnesota counties places it squarely in the middle tier. A median home value of $422,000 translates into an annual real-estate tax bill of $4,164, while median household income reaches $115,345 and per-capita income is $56,954. Saint Paul anchors the county as its largest city. The picture that emerges is a county taxing near the state norm but well above what much of the country pays, suggesting homeowners here should expect property taxes that track Minnesota’s broader patterns rather than standing out in either direction.

Frequently asked questions

What is the property tax rate in Washington County, MN?
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 ($422,000), the estimated annual bill is about $4,164.
Is Washington County's rate high or low?
Compare it to the state median of 0.98% 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 Washington 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 Washington County assessor within the local deadline, typically with comparable sales as evidence.
