Property tax and home values in Idaho
In 2024, Idaho homeowners paid a median of $1,912 a year in property tax, and the median owner-occupied home was worth $446,400, according to the Census Bureau's American Community Survey. Dividing the tax by the value gives an effective rate of about 0.43% of the home's value each year.
That ranks Idaho 3rd lowest of the 50 states and DC, one of the lowest rates in the country, and 52% lower than the US figure of 0.89%. The median home value is 24% above the US median of $360,600. On a $446,400 home, Idaho's rate works out to about $1,920 a year, $2,053 a year less than the $3,973 it would pay at the national rate.
Example: the payment on a median Idaho home
Take the median price of $446,400 with 20% down ($89,280), a $357,120 loan for 30 years, and an example rate of 6.5%. The 6.5% is only an example to show the math, not today's rate; type in the rate you're quoted.
With P = $357,120, i = 0.065 ÷ 12 and n = 360, principal and interest is $2,257.24 a month. Property tax at 0.43% adds $159.96 and insurance (assumed $1,800 a year) adds $150.00. With 20% down there's no PMI, so the full payment is $2,567.20 a month.

When these numbers don't fit your home
- The 0.43% is a statewide figure. Your county, city, school district and any homestead or senior exemption set your real bill, which can be well above or below it. Check the county assessor or the listing's tax history.
- It's a ratio of two medians (median tax ÷ median value), so it's a guide, not anyone's actual rate.
- Insurance varies a lot by location and home. $1,800 a year is just a starting assumption; get a quote.
- Survey figures carry a margin of error, and home values have moved since 2024.
