Montana Tax Overview for Estimated Payments

Montana has a two-bracket income tax system with rates of 4.7% and 5.65%, with the top rate applying to income above $47,500. Montana recently simplified from a more complex multi-bracket system. Montana has no statewide sales tax, which improves overall purchasing power for residents. No Montana city charges a local income tax. Montana's standard deduction mirrors the federal amount ($16,100 for single filers), which is generous. Compared to neighboring Idaho (5.3% flat) and Wyoming (no income tax), Montana falls in the middle. Montana's combination of no sales tax and moderate income tax rates makes it moderately tax-friendly overall, though the growing Bozeman and Billings metro areas have a higher cost of living than the tax burden alone suggests.
