How Boise Property Tax Bills Are Calculated

Boise property tax bills result from multiplying taxable value by the combined levy rates of every taxing district serving a parcel. Taxable value starts with the assessor’s full market value, then subtracts the homeowner exemption and any other qualifying reductions. Each year, the county auditor calculates district rates based on budgets submitted by cities, schools, counties, and special districts.

• Step 1: Assessor determines full market value under Idaho Code § 63-205.
• Step 2: Homeowner exemption reduces taxable value under § 63-602G.
• Step 3: Additional exemptions apply for seniors, veterans, or disability.
• Step 4: County auditor multiplies taxable value by district levy rates.
• Step 5: Treasurer mails the bill according to the schedule published by the county.
