Idaho Homeowner's Exemption: 50% Off, Up to $125,000, Plus a Separate Circuit Breaker

Updated August 2026

Idaho's base Homeowner's Exemption is available to every owner-occupant with no income test. A separate, more restrictive Property Tax Reduction ('Circuit Breaker') program is layered on top for lower-income seniors and disabled homeowners.

Every Idaho owner-occupant can exempt half their home's assessed value, capped at $125,000, no age or income requirement. On top of that, income-qualified seniors, disabled, and a few other categories can apply for an additional formula-based reduction through the Circuit Breaker program.

Deadline and form: Apply and occupy by April 15 (Form HO-49 (varies slightly by county)). Citation: Idaho Code § 63-602G.

Property Tax Reduction ("Circuit Breaker")

What it does: Reduces property tax by $250 to $1,500 per year, formula-based on income and tax liability.

An exemption or credit lowers your bill only after the assessed value is set. If that value is too high to begin with, you are overpaying on everything above it regardless of which relief programs you claim. Nobody checks the underlying value unless you do.

How to Apply

Contact your county assessor's (or, where noted above, your state revenue department's) office for the current application form
Gather proof of ownership, occupancy, and, for income-tested programs, your prior-year income documentation
File before the deadline listed above, most jurisdictions do not accept late applications for that tax year
Confirm the relief shows up on your next assessment notice or tax bill

The Bottom Line

The base exemption is generous and universal; the Circuit Breaker is the piece that's actually restricted. If you're not 65, disabled, or otherwise in a qualifying category, you only get the base 50%/$125,000 exemption, which is still substantial.

Note: Program names, dollar figures, and income limits above are current as of August 2026 and are set or adjusted by the state legislature or department of revenue, not by AppealDesk. Some figures adjust annually, confirm the current-year number with your county or state before applying. AppealDesk helps homeowners identify available relief programs and appeal overassessments.

Most homeowners stack these programs on top of whatever value the assessor assigned and never question the value itself. It came from a mass-appraisal model, not an individual review of your home. It is worth checking once.
