Property Taxes in Idaho: Rates, Exemptions, and How They Work (2026)
TL;DR
Idaho property taxes are assessed at 100% of market value. The average effective rate is about 0.53%. The homeowner's exemption reduces the assessed value of a primary residence by 50%, up to a maximum dollar amount (currently around $125,000). Idaho's rapidly growing housing market has caused sharp assessment increases in many areas. The Circuit Breaker program provides property tax reductions for qualifying low-income homeowners. Appeal to the county Board of Equalization by the fourth Monday in June.
Assessment
County assessors value all property at 100% of current market value as of January 1. Idaho's rapid population and home price growth has caused large annual assessment increases in many counties.
Homeowner's Exemption
Owner-occupied primary residences receive a 50% reduction in assessed value, capped at a maximum amount set annually by the Idaho Tax Commission (approximately $125,000 in recent years). This means the first $250,000 of a home's value is effectively taxed at half the rate.
Other Exemptions
| Program | Benefit | Who Qualifies |
|---|---|---|
| Circuit Breaker | Up to $1,320 property tax reduction | 65+, disabled, widow(er), blind, former POW, income under $33,870 |
| Disabled Veterans | Up to $1,320 reduction (or full exemption for 100%) | Service-connected disability |
3% Revenue Cap
Idaho law limits the annual increase in property tax revenue for each taxing district to 3% plus revenue from new construction. This is a revenue cap, not an assessment cap. Your individual bill can increase more than 3% if your property's value increased faster than the district average.
Appeal
- County Board of Equalization: File by the 4th Monday in June
