How to Appeal in Montana

1

Check your assessment notice

Your county assessor mails assessment notices — usually in spring. The notice shows your assessed value and the appeal deadline. In most states you have 30–90 days from the notice date.

2

Gather comparable sales

Find 3–5 similar properties in your neighborhood that sold recently at prices below your assessed value. Use Zillow, Redfin, or your county recorder's public records. The more recent and similar the sales, the stronger your case.

3

File your formal appeal

In Montana, you file with the County Tax Appeal Board. File written appeal with the County Tax Appeal Board within 30 days of your Notice of Classification and Appraisal. File before 30 days after assessment notice.

4

Present your evidence at the hearing

Show up with your comparables. Be calm and factual. You don't need a lawyer. Appeals boards are accustomed to homeowners representing themselves. Simply demonstrating that comparable properties sold for less than your assessment is often enough to win a reduction.
