Idaho has a very low effective property tax rate of 0.46%, ranking 46th nationally. Rapid population growth from California transplants has pushed home values sharply higher, though the state's circuit breaker and exemption programs provide some relief.
Idaho assesses property at 100% of market value. The homeowner's exemption then reduces the taxable value before mill rates are applied. Mill rates vary significantly between urban Boise-area counties and rural counties.
| Home Value | Estimated Annual Tax | Monthly (Escrow) |
|---|---|---|
| $250,000 | $1,150 | $95/mo |
| $366,100 (median) | $1,684 | $140/mo |
| $600,000 | $2,760 | $230/mo |
Idaho's homeowner exemption exempts 50% of the value of an owner-occupied home, up to $125,000 in 2024. A property tax reduction (circuit breaker) program is also available for lower-income homeowners and seniors.
Idaho property taxes are due in two equal installments: December 20 (first half) and June 20 (second half).
Ada County (Boise) has experienced dramatic appreciation, raising actual dollar tax bills significantly despite the low rate. Sun Valley area (Blaine County) has high values but benefits from the same low statewide structure.
