What’s specific to Montana
State and local income tax on this page reflects MT brackets and any modeled local wage overlays from our committed tax tables—not federal income tax. Qualified retirement plan/IRA distributions generally taxed like ordinary income unless a specific exclusion applies. Groceries follow the USDA Moderate-Cost tier scaled by BEA state regional price parities, with household-size adjustments matching the homepage explorer.
