Learn moreIdaho's flat 5.3% state income tax
Idaho levies a real, current flat individual income tax of 5.3%, cut from 5.695% via House Bill 40 (signed March 2025) -- the endpoint of five consecutive years of rate cuts. This is a real, current, statewide rate, not Post Falls-specific.
Idaho's 6% sales tax, with zero Post Falls local add-on
Idaho's flat statewide sales tax runs 6%, and Post Falls is not one of Idaho's small, tourism-dependent 'resort cities' (Sun Valley, Ketchum, McCall) eligible for a voter-approved local-option add-on -- so the combined rate paid in Post Falls is simply the flat 6% state rate.
Kootenai County's genuinely low property tax rate
Post Falls shares Kootenai County's effective property tax rate with Coeur d'Alene -- a real, disclosed spread across aggregators reviewed (0.36% per one specific citation, 0.64% per another), against Idaho's own statewide median of roughly 0.43%. A specific parcel's actual bill varies by taxing district; confirm directly with the Kootenai County Assessor.
