The property tax system in Idaho is a principal source of funding for many things. For example, local-level public services, school districts, and local governments.
In addition, taxes levied on property also fund long-term investments, such as infrastructure development and capital projects.
In 2015, the Idaho taxing district collected $1.6 billion in property taxes. Municipal governments took a 26.7 percent share, while the county government pocketed 26.4 percent. School districts took the lion’s share of the revenue – accounting for a 30.1 percent share.
Property taxes in the Gem state are relatively low when compared to the rest of the nation. While a typical Idaho homeowner pays $1,276 every year, the average homeowner elsewhere pays $920 more.
Homeowners Exemption in Idaho
One reason to explain this significant difference in property tax is the homeowner’s exemption. The exemption, capped at a value of $100,000 for the year 2018, exempts all owner-occupied primary residents by fifty percent of the property’s market value.
Let’s take a look at Idaho property taxes in a little more detail.
How do Idaho Property Taxes Work?
Homeowners can pay Idaho property taxes in two installments. The first installment is due on the 20th of every December while the second installment is due the 20th of June.
The taxes levied are based on your property’s full market value. Each county assessor helps determine the full market value of every property. Generally speaking, the county assessor uses comparative data from recently sold homes to come up with your home’s market value.
Once the value has been assessed, it’s only then that exemptions can be applied. In Idaho state, the biggest tax exemption is the homeowner’s exemption.
As already mentioned, it’s equal to fifty percent of the home’s value and one acre of land and can only be claimed on an owner-occupied primary residence.
The homeowner’s exemption is for people that live in the property they have purchased. However, for people who are looking to buy real estate as an investment and have tenants living in the property, this homeowner’s exemption isn’t available.

Let’s take a look at an example. If your home is assessed and valued at $200,000 then with the 50% homeowner’s exception your total taxable value would be $100,000.
Other special exemptions are available to certain groups that meet income requirements, including widows and widowers, blind homeowners, minors without parents, former prisoners of war, and people aged 65 and older.
In addition to the base city/county tax rate, there is generally additional add-on fees to be aware of, such as Bonds and Supplements.
