Idaho Property Taxes Explained for Homeowners and Buyers

Idaho's property tax rates are among the most favorable in the western United States, but understanding the system helps you budget accurately and take advantage of available exemptions.

How Idaho Property Taxes Are Calculated

Idaho property taxes are based on assessed value, which is set by the county assessor. The tax is calculated by multiplying the net taxable value by the local levy rate, which varies by school district, city, and special taxing districts.

The Idaho Homeowner's Exemption

Idaho offers a Homeowner's Exemption for owner-occupied primary residences. This exemption reduces the taxable value of your home, resulting in lower property taxes. To receive the exemption, you must apply with the county assessor after purchasing and occupying the home.

Bonneville County vs. Madison County Rates

Levy rates vary meaningfully between counties and even between taxing districts within counties. Idaho Falls and Ammon properties in Bonneville County, for example, may be in different levy districts with different total rates. We always advise buyers to request the specific tax history for any property they're considering.

Property Tax on New Construction

Newly constructed homes are assessed based on the county's estimate of market value for the improved property. Tax bills for the first year can be lower than expected if the home was completed mid-year — but will normalize to a full-year assessment going forward.

Circuit Breaker and Other Programs

Idaho offers additional property tax relief for seniors and disabled residents through the 'Circuit Breaker' program. Qualifying homeowners may be eligible for significant reductions in their property tax burden.
