What the calculator does
For each gross salary, it applies the 2026 federal brackets, FICA (6.2% Social Security up to the $184,500 wage cap + 1.45% Medicare on everything), then Montana's state income tax using the brackets above. Pre-tax deductions (401(k), HSA, etc.) reduce your taxable income before any of the above runs.
