How Property Tax Works in Boise
Homeowners in Boise pay property tax to multiple overlapping jurisdictions: Ada County, the city of Boise itself, school districts, and other special-purpose districts. The effective rate shown on this page combines all of these into a single percentage applied against the assessed value of the property.
Each jurisdiction sets its own rate ("millage") annually, typically during the budget process. The total bill is paid to the county tax collector, which distributes revenue back to the individual jurisdictions.
Who Assesses Your Home
Your home's assessed value is determined by the Ada County assessor's office. Assessments usually happen on a defined schedule (annual, biennial, or longer depending on the state) and are based on recent comparable sales, property characteristics, and market conditions. Homeowners have the right to appeal the assessed value if they believe it exceeds fair market value.
Exemptions to Check
Most states offer exemptions that reduce the taxable value of your home. The most common are the homestead exemption (for primary residences), senior exemption (for homeowners over 65), veteran exemption, and disability exemption. Contact the Ada County assessor's office to apply.
