Montana taxes cigarettes and alcohol through excise taxes that are embedded in the shelf price rather than added at the register — and because Montana has no general sales tax, that excise is the entire state tax. Cigarettes are taxed at $1.70 per pack, beer and wine at per-gallon rates, and spirits through the state’s liquor control markup. This tool estimates the excise on a purchase.
How it works
Each item is multiplied by its per-unit excise and summed:
cigarette tax = packs × $1.70
beer tax = gallons × $0.139
wine tax = gallons × $1.06
spirits tax = (liters × 0.264172) × $9.74/gal equivalent
total = sum of the above
The spirits figure is an effective per-gallon equivalent of the state markup and taxes, since Montana sells distilled spirits through its control system rather than levying a simple per-gallon excise.
Example and notes
A single pack of cigarettes carries $1.70 of Montana excise. A 5-gallon purchase
of wine adds about 5 × 1.06 = $5.30, and a 0.75-liter bottle of spirits carries
roughly 0.198 × 9.74 = $1.93 of effective spirits tax. None of these have
sales tax stacked on top in Montana. Beer rates are tiered by brewery size and
spirits pricing shifts with state markup, so confirm current rates with the
Montana Department of Revenue.
