Idaho property tax calculator
Homeowners in Idaho pay a median of $2,038 each year, based on 0.49% of the $418,600 median home value.
This is an estimate, not a bill. Your county assessor sets your value, while local taxing units set the rates; in some states, an appraisal district handles the assessment. Check with your county before paying or protesting.

Homestead Exemption in Idaho
Homeowner's Exemption is also called the Homestead Exemption. For owner-occupied primary residences, including manufactured homes, the exemption covers 50% of the home's value and up to one acre of land, with a $125,000 cap. No income or age limits apply.
How to apply: Submit your application through your county assessor's office. Ada County offers an online assessor application form. You can also download it and deliver it to the office by mail, email, or hand delivery. Approval usually means you do not have to apply again.
Filing deadline: Ada County requires you to own and occupy the home and file by the county's last working day in December before business closes. For newly built homes, the application is due within 28 days after the assessment notice.

Appealing an Idaho property tax assessment
APPEAL BYMail or a hearing pronouncement of the BOE decision starts a 30-day period
County Board of Equalization decisions can be appealed by filing an appeal notice with the county clerk or auditor. The deadline is 30 days after mailing or announcement at the hearing. The clerk forwards the appeal notice to the Board of Tax Appeals.
At the first hearing, the County Board of Equalization makes the decision. You can then appeal that decision to the Idaho Board of Tax Appeals. District court is another option.

Exemption for disabled veterans in Idaho
Veterans with disabilities may receive up to $1,500 off property taxes in Idaho. This applies to their home plus as much as one acre of land. There is no income limit. The VA must recognize you as 100% service-connected disabled, or you must receive the 100% unemployability rate.

How Idaho sets your home's value
In the state's worked example, a home and its lot are valued at 100% of market value. The homeowner's exemption is then subtracted to determine the taxable value.

Additional Idaho property tax rules you should know
- You see the Homeowner's Property Tax Relief credit on your tax bill in Idaho when you have the Homestead Exemption no later than the second Monday in July. It was created in 2023 by House Bill 292. You do not need to file a separate application.
- After approval, the exemption remains in place until the home changes ownership or you no longer use it as your primary residence. Each new owner must submit another application.
- The tax is recovered, along with a penalty equal to the exempted tax, when you claim more than one Homestead Exemption. Following the assessor's denial or recovery notice, you have 30 days to appeal the penalty.
- Ada County requires a Homestead Exemption application within 28 days after the assessment notice for a newly constructed home to qualify for the current year. A 30-day period is allowed by some other Idaho counties.
