How Property Taxes Work in Idaho

In Idaho, property taxes fund essential local public services such as public schools, emergency services, county roads, and local health programs. Taxes are administered at the county level and calculated using local valuations and tax rates.

1

Assessment

Your county tax assessor determines the fair market value of your property. The taxable assessed value is calculated as a percentage of this market value, minus any exemptions.

2

Local Tax Rate / Millage

Local tax districts (counties, cities, and school systems) set millage rates annually. One mill is equal to $1 of tax per $1,000 of assessed property valuation.

3

Final Bill & Exemptions

Your final bill is calculated by applying the combined local tax rates to your taxable assessed value after subtracting any qualified exemptions.

Standard Calculation Formula
Estimated Tax = (Assessed Value − Exemptions) × Local Rate
🧮

Example Calculation for Idaho

For a home valued at $300,000 in Idaho, the annual property tax bill is approximately $1,384, based on the average effective rate of 0.46%. Your actual bill will vary based on your local county and city rates. Use our tax calculator to compute your estimate with local county rates.
