Learn moreIdaho's flat 5.3% state income tax
Idaho's flat individual income tax rate was cut from 5.695% to 5.3% via House Bill 40, signed by Governor Brad Little in March 2025 -- applying statewide to Star residents the same as any other Idaho resident. This is a genuinely different tax picture from the no-income-tax states built elsewhere in this project.
Ada County's property tax rate
Ada County's effective property tax rate carries a real, disclosed spread of roughly 0.46%-0.76% across the methodologies reviewed in this project's Ada County records (see meridian-id.js); this record uses 0.52% as a representative figure, consistent with this batch's companion kuna-id.js record.
A flat 6% sales tax, no Ada County local add-on
Star pays Idaho's flat 6% statewide sales tax with zero local-option add-on, since Ada County does not impose one -- distinct from Idaho's voter-approved resort cities that layer a further local rate on top.
Insurance: a real, general Treasure Valley wildfire consideration
Star sits within the broader Treasure Valley, where growing, disclosed wildfire risk has been driving up homeowners insurance costs in Foothills-adjacent parts of the region (see boise-id.js) -- confirm current insurance availability and cost directly for a specific Star address, particularly toward the city's more rural western edges.
