Idaho Homestead Exemption: 2025 Guide for Homeowners
Idaho's homeowner's property tax exemption — sometimes called the homestead exemption — is one of the simplest ways to lower the property tax bill on your primary residence. Here's how it works, who qualifies, how to apply, and the deadlines to remember.
What the homeowner's exemption does
The exemption reduces the taxable value of your primary residence by 50% of the home's value and the land it sits on (up to one acre), subject to a maximum dollar cap set each year by the Idaho State Tax Commission. Your property is still assessed at full market value — the exemption simply lowers the portion that property taxes are calculated against.
Who qualifies
- You own the home (as an individual or through a qualifying trust).
- It is your primary residence — where you live more than half the year.
- You owned and occupied the home by April 15 of the tax year.
- The property is not used primarily for business.
How to apply
- 1Contact your county assessor's office. Each Idaho county handles the application — Ada, Canyon, Bonneville, Madison, and so on. Most counties offer the form online.
- 2Complete the homeowner's exemption application. You'll provide your name, parcel number, and a declaration that the home is your primary residence.
- 3File by the April 15 deadline. Applications received after April 15 may not take effect until the following tax year.
- 4Keep it on file. Once approved, the exemption follows the property as long as you continue to own and occupy it as your primary residence.
A note on the Circuit Breaker program
Idaho also offers a separate Property Tax Reduction (Circuit Breaker) program for qualifying seniors, widowed individuals, individuals with disabilities, and certain veterans. It is separate from the homeowner's exemption and has its own income and residency requirements — ask your county assessor whether you qualify for both.
Common questions
Does it transfer when I move?
No. The exemption is tied to the property. When you buy a new primary residence in Idaho, you apply again with that property's county assessor.
Does it apply to a rental or second home?
No. Only your primary residence — the home you actually live in — is eligible.
What if I bought my home mid-year?
If you closed and moved in before April 15, you can apply for that tax year. Otherwise the exemption takes effect the next year.
