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.

Frequently asked questions

What is the property tax rate in Silver Bow County, MT?
The effective rate is 0.98% — meaning the median tax bill equals about 0.98% of the median home value.
How much are property taxes on a median home?

Is Silver Bow County's rate high or low?

How does the effective rate differ from my mill rate?

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