Gambling tax in Montana
Montana has the simplest graduated structure in this calculator: two bands, 4.7% below $20,500 and 5.9% above it. Losses offset winnings when you itemize federally, so a bettor taking the standard deduction faces the state rate on gross winnings rather than on profit.
Montana at a glance
One boundary, and most bettors are already past it
With a single switch point at $20,500, Montana is easy to reason about: if your total taxable income clears that figure, and for most working bettors it does, every dollar of winnings is taxed at 5.9%. There is no ladder to climb and no planning to do. The useful comparison is against the flat states, because that is effectively what Montana is above the threshold, and 5.9% is higher than every flat rate in this tool. A Montana bettor pays more on the state line than one in any single-rate state.

Are gambling losses deductible in Montana?
Yes. Montana takes its gambling income figure from the federal return, so the offset depends on itemizing there.
