How Does the Idaho Property Tax Calculator Work?
Use this Idaho property tax calculator to estimate your annual property tax bill. Enter your property's assessed value and our calculator applies Idaho's median effective tax rate of 0.42% to generate an estimated bill.
Enter your property's estimated assessed value — the value your county assessor assigns to your property, which is typically lower than market value after exemptions. Our calculator uses the median effective tax rate (actual bills divided by assessed market value), accounting for typical exemptions and providing a more accurate estimate than the statutory rate alone.
Note: your assessed value reflects any exemptions you currently hold. Your actual bill may be higher or lower depending on local levies, special assessments, and individual exemption eligibility. Idaho's median property tax bill is $1,726, well below the national median property tax bill of $2,400. Bills vary widely across the state, from $540 in Clark County to $2,911 in Latah County, a difference of $674.

Below, compare any Idaho county's effective rate to other counties in the state or the national median of 1.02%.

Property Tax Assessment Values Across Idaho
Understanding the distinction between "market value" and "assessed value" is crucial when examining property taxes in Idaho.
The market value is what a willing buyer would pay to a willing seller in an open and competitive market. Location, property condition, and economic market trends often influence it. Each Idaho county assessor estimates the market value for tax purposes.
The assessed value is the market value minus any applicable exemptions or limits determined by local laws and offerings. The tax assessed value is the figure used to calculate your property taxes or the amount multiplied by your tax rate to get your tax bill.
Assessment notices:
In Idaho, assessment notices are sent in the spring each year. They'll typically reach your mailbox by the end of March.
Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill. Idaho’s median home price is $389,309, and the median property tax bill is $1,726, below the national median property tax bill of $2,400. For example, Blaine has the highest median home price at $849,641.

Property Tax Bills Across Idaho
How much are property tax bills across Idaho?
Property tax bills in Idaho are calculated by multiplying the property's assessed value by the local effective tax rate. The assessed value is determined by the county assessor and reflects the market value of the property minus any applicable exemptions.
Idaho homeowners face varying tax obligations depending on their location. The median tax bill in Latah County is $2,911.00, while homeowners in Clark County pay a median of $540.00.
Factors including property size, recent improvements, and neighborhood comparables all influence the final assessed value, and therefore the tax bill.
