How Property Tax Is Calculated in Idaho

Property tax in Idaho is based on the assessed value of real property, which is generally 60 % of the market value as determined by the county assessor. The assessed value is then multiplied by the local tax levy (expressed as a percentage or “mills”) set by the county, city, school district, and other taxing entities. The resulting amount is the annual property tax bill.

Note: The effective property tax rate (total tax ÷ market value) for the state averages 0.53 %, but actual rates can differ between counties and municipalities because each jurisdiction adopts its own levy.

Example Tax Bills

Using the statewide average effective rate of 0.53 %:

Home value	Approximate annual property tax*
$250,000	$1,334
$500,000	$2,667

* Calculated as Home value × 0.53 %. The figures represent a baseline; the actual bill may be higher or lower depending on the specific county levy and any exemptions that apply.

Variation by County

Idaho has 44 counties, each with its own tax levy. For example:

County	Effective tax rate (2026)
Ada (includes Boise)	~0.58 %
Canyon	~0.51 %
Kootenai (includes Coeur d’Alene)	~0.45 %
Rural counties (e.g., Lemhi)	often below 0.40 %

Because levies are set locally, property tax rates can vary by county, and the statewide average of 0.53 % masks this geographic diversity.

Comparison to the National Average

National average effective property tax rate (2026): 0.97 %
Idaho’s effective rate: 0.53 %

Idaho’s rate is 44.87 % lower than the national average, placing the state among the ten jurisdictions with the lowest effective property tax rates in the United States.

Considerations for Retirees and Landlords

Retirees

Tax burden: The lower effective rate means that, on average, retirees who own a home in Idaho pay less in property tax than the typical U.S. homeowner.
Exemptions: Idaho offers a senior citizen exemption that can reduce the taxable value for qualifying owners (age 65+ with income limits). Eligibility is determined at the county level.

Landlords

Rental properties: Property tax is assessed on the underlying real estate regardless of occupancy. The same effective rate (0.53 %) applies to rental units.
Deductibility: For federal income‑tax purposes, landlords may deduct property taxes as an operating expense, consistent with IRS rules.
County differences: Landlords owning properties in multiple counties should account for varying local levies when estimating annual tax costs.
