Idaho property tax averages about 0.63% of a home’s value each year. This estimator applies that statewide effective rate to your home value to project an annual and monthly property tax bill for Idaho in 2026.
How it works
Idaho’s average effective property tax rate is 0.63% — the statewide ratio of property tax actually paid to market value. The estimate applies that rate to your home’s value after any homestead exemption:
taxable value = home value - homestead exemption
annual tax = taxable value x 0.63%
monthly tax = annual tax / 12
Idaho does not apply a single flat statewide homestead value exemption in this model, so the estimate is the rate applied to your full value; any local exemptions or credits you receive would lower the bill.
Example
Take a $400,000 home in Idaho. With no homestead exemption applied, the estimated annual tax is $400,000 × 0.63% = about $2,520 ($210 per month).
Notes
This is an estimate only and not financial or tax advice. It uses Idaho’s 0.63% statewide average effective rate; your actual bill depends on local county, city, and school-district millage, assessment ratios, assessment caps, and any local exemptions or credits. For an exact figure, confirm with the Idaho State Tax Commission and your county assessor.
