How sales tax works in Idaho
Idaho charges 6% statewide with almost no local sales taxes — only a handful of resort cities add a small local option tax. Groceries are taxed, but the state offers an annual grocery tax credit on income tax returns to offset it.
Rates are approximate and current as of the 2024–2025 tax years. Local rates change and vary by address; confirm the exact figure with the Idaho department of revenue or a rate lookup by ZIP code before relying on it.
