Property Taxes in Boise
Boise property taxes reflect Idaho's genuinely low statewide structure (roughly 0.49%-0.53% average effective rate) applied to Boise's relatively higher home values, producing a Boise-specific median effective rate around 0.59% -- still well below the ~1.02% national median -- with a real, meaningful homeowner's exemption available to primary residents.

Learn moreA Genuinely Low Rate, Even With Boise Running Above the Statewide Average
Idaho's statewide average effective property tax rate runs approximately 0.49%-0.53% depending on source, among the lowest in the country. Boise itself runs somewhat higher within that picture -- a median effective rate around 0.59% based on actual Ada County property records, the highest among Ada County's own cities (Garden City runs lowest, around 0.52%) -- reflecting Boise's relatively elevated home values rather than an unusually high nominal rate. Even at that higher end, Boise remains well below the roughly 1.02% national median effective rate.
Real, Meaningful ZIP-Code Variation Within Boise Itself
Boise's effective property tax rate varies meaningfully by ZIP code: the 83702 ZIP (closer to the North End/urban core) carries a disclosed median effective rate around 0.77%, while 83709 (a more suburban southwest ZIP) runs closer to 0.43% -- confirm the actual current rate for a specific address directly with the Ada County Assessor rather than relying on any single citywide figure.
Idaho's Homeowner's Exemption Is a Real, Meaningful Reduction
Idaho exempts 50% of a primary residence's assessed value from property tax, capped at $125,000 of exempted value (raised from a prior $100,000 cap in 2021) -- filed annually with the Ada County Assessor, generally by an April 15 deadline. This is a real, genuinely meaningful reduction for owner-occupants specifically, not available to non-owner-occupied or investment properties.
Confirm the Actual Bill for a Specific Property
Given the real complexity introduced by overlapping taxing districts (city, county, school district, highway district, and others, each with its own levy), confirm the actual current property tax bill for a specific Boise property directly with the Ada County Assessor's office rather than relying on any single citywide or statewide percentage figure in this file.
Idaho's Tax Structure Rewards Long-Term Owner-Occupants Specifically
Between the homeowner's exemption (available only to primary residents) and Idaho's genuinely low statewide rate structure, Idaho's property tax system is real, structurally favorable to long-term owner-occupants specifically -- a distinction worth understanding for investment-property buyers, who do not receive the homeowner's exemption and should budget accordingly.
