If you bought a home in Idaho Falls, Pocatello, Rexburg, Blackfoot, or anywhere else in Southeastern Idaho this year, put one more item on your fall to-do list: the Idaho homeowner’s exemption. It’s one of the biggest property tax breaks available to Idaho homeowners, it isn’t automatic, and for the 2026 tax year the window to apply closes at the end of the year. Here’s how it works, plus where local home prices sit right now.
What is Idaho’s homeowner’s exemption?
Under Idaho Code Section 63-602G, the market value of an owner-occupied primary home is partly exempt from property tax. The exempt amount is 50% of the home’s assessed value or $125,000, whichever is less. The Idaho State Tax Commission explains that the exemption covers the home and up to one acre of land, and that manufactured homes used as a primary residence can qualify too.
The cap has gone up over time. According to the Tax Commission’s history table, the maximum was $100,000 from 2017 through 2020 and has been $125,000 since 2021.
What that means at today’s Southeastern Idaho prices
The 50% rule only matters for lower-value homes. Once the home and its first acre are assessed above $250,000, the exemption tops out at $125,000. Here’s where recent sale prices sit in the region:
- Idaho Falls: Redfin reports a median sale price of $359,829 for the three months ending September 2026, up 0.1% from a year earlier, with a median of 38 days on market. The Zillow Home Value Index puts the typical Idaho Falls home value at $394,199, up 1.6% over the past year (updated September 30, 2026).
- Pocatello: Redfin shows a median sale price of $339,738 for the three months ending September 2026, up 1.4% year over year, with a median of 36 days on market.
- Rexburg: Redfin reports a median sale price of $397,811 for the same period. It’s up 18.0% year over year, but Rexburg’s sales volume is small (52 homes sold in September), so the median can swing a lot from month to month.
At those medians, half the value would be well over $125,000, so a typical buyer in any of these cities would get the full $125,000 exemption. For example, a home assessed at $359,829 would be taxed on roughly $234,829 instead of the full value. The dollar savings depends on your local levy rate, which your county assessor or treasurer can look up for your parcel.
A buyer-friendly market to keep in mind
Realtor.com’s October 2026 Idaho Falls snapshot shows 724 active listings (up 7.04% from a year ago), a median list price of $427,500 (down 2.71% year over year), and homes selling for about 2.09% below asking on average. Realtor.com calls Idaho Falls a buyer’s market for October 2026. If you’re still shopping, factor the exemption into your estimated monthly payment.
Who qualifies
Idaho Code 63-602G(2) sets the basic requirements:
- You own the home and live in it as your primary residence. The statute calls this your “true, fixed and permanent home.”
- You claim only one exemption. You can’t have an exemption on another homestead in the same county or apply in another county.
- You provide Idaho ID information. The application asks for your Idaho driver’s license or state ID number. If you’ve just moved to Idaho and don’t have one yet, the statute gives you 90 days after applying to provide it.
Homes held in a trust or LLC can still qualify, but the assessor will ask for extra paperwork (an affidavit under Idaho Code 63-703(4)).
The deadline: why fall buyers should act now
Idaho Code 63-602G(5) says that to get the exemption for the current tax year, you must apply by the close of business on the county’s last business day of the year. For 2026, that’s Thursday, December 31. The statute also says:
- The exemption is not prorated. If your application is complete and approved, the full exemption applies as of January 1 of that tax year, even if you closed in October.
- Approved applications received after the second Monday in July are granted as tax cancellations, so late-year buyers still get the benefit for that year.
The Bannock County Assessor (Pocatello) and the Bingham County Assessor (Blackfoot) both list December 31 as the last day to apply for the current year. Newly built homes follow a separate timeline. The Bonneville County Assessor (Idaho Falls) and Bingham County both say to apply within 30 days of receiving the occupancy assessment notice. If you bought new construction, watch your mail.
How to apply in Southeastern Idaho
You apply through the assessor in the county where the home is located, not through the state. The main county offices:
- Idaho Falls / Ammon: Bonneville County Assessor, Homeowner’s Exemption
- Pocatello / Chubbuck: Bannock County Assessor
- Rexburg: Madison County Assessor
- Blackfoot: Bingham County Assessor, Homeowners Exemption
A few practical tips from those county pages:
- Bring proof of ownership. Bonneville County asks for a recorded deed or contract.
- Look for confirmation. Bingham County says your exemption isn’t valid until you get back a copy stamped “RECEIVED.” Bannock County says it doesn’t mail approval notices, so check your annual assessment notice.
- Re-check after paperwork changes. Bonneville County notes that a refinance, a new deed, or moving the home into a trust or LLC can mean you need to reapply.
Other Idaho property tax relief worth knowing
Once your homeowner’s exemption is in place, you may qualify for more help. The Tax Commission’s Property Tax Reduction program (often called the “circuit breaker”) can cut property taxes by $250 to $1,500 for qualifying homeowners. For 2027, applicants generally need total 2026 income of $40,030 or less after medical expenses, must be 65 or older, blind, widowed, disabled, a former POW or hostage, or a fatherless or motherless child under 18, and must already have a homeowner’s exemption. Applications are accepted January 1 through April 15, 2027.
Finally, keep the payment calendar in mind. Under Idaho Code 63-903, property taxes are due December 20. You can pay the full amount then, or pay the first half by December 20 and the second half by June 20.
Frequently asked questions
Do I have to reapply for the homeowner’s exemption every year?
No. Under Idaho Code 63-602G(4), you apply once. The exemption continues as long as you own the home and live in it as your primary residence. You’ll need to reapply if ownership changes, for example if you sell, add an owner, or move the home into a trust.
Can I get the homeowner’s exemption on a rental property?
No. The home has to be owner-occupied and your primary dwelling. Investors who buy a rental in Pocatello or Idaho Falls won’t get this exemption on that property. If an exemption is claimed improperly, the county can recover up to seven years of back taxes plus interest and late charges.
I bought my house in the fall. Do I lose part of the exemption?
No. Idaho law says the exemption isn’t prorated. If you file a complete application by the county’s last business day of the year and it’s approved, you get the full exemption for that tax year.
