Almost every state that taxes income taxes capital gains at the same rate as wages. Montana is an exception: it applies a lower rate to long-term capital gains, mirroring the federal system's distinction between ordinary income and investment returns.

The practical effect is that Montana favours income from assets over income from work, which is unusual at state level and matters considerably for anyone with meaningful investment income or a business sale in prospect.

Montana's 2024 reform simplified the ordinary-income schedule to two brackets and raised the standard deduction to match the federal figure. Combined with the capital gains treatment, the state's effective burden is lower than its 5.65% top rate suggests for people whose income is not purely wages.

Montana has never levied a general sales tax, and voters have consistently rejected proposals for one. The state instead permits certain resort communities — Whitefish, Big Sky, West Yellowstone and a handful of others — to levy a local resort tax on lodging, restaurants and retail.

The design is deliberate: those communities carry visitor numbers far beyond their resident populations, and the resort tax shifts the cost of the resulting infrastructure onto tourists. For residents elsewhere in Montana, there is no sales tax at all.

Property taxes have risen sharply in recent years as valuations in western Montana climbed with in-migration, and property tax relief has become the dominant state political issue in much the same way it has in Nebraska.

Montana taxes Social Security benefits, following the federal treatment — one of a shrinking group of states that still does. Taxpayers whose benefits are partly taxable federally will generally find them partly taxable in Montana too.

Montana previously allowed a deduction for federal income tax paid, but the 2024 reform eliminated it alongside the rate simplification, so the headline cut was partly offset.

No Montana city or county levies an income tax, and the state runs no disability or paid leave programme, so a Montana payslip carries federal deductions plus state income tax only.
