Idaho Property Tax Appeal — Key Facts
How to Appeal in Idaho
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.
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.
File your formal appeal
In Idaho, you file with the County Board of Equalization. File written protest with the County Assessor or Board of Equalization. Hearings are held in July. File before December 1 (4th Monday of June for appeal to Board of Equalization).
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.
