Worked examples
An $80 restaurant bill in Whitefish (3% resort tax)
| Rate | 0% state + 3% local = 3% |
|---|---|
| Price before tax | $80.00 |
| Sales tax | $2.40 |
| Total | $82.40 |
Working: $80.00 × 3% = $2.40. Whitefish charges a 3% resort tax on restaurant meals. The same meal in Billings or Missoula would have no tax at all.
Working back from a $257.50 ski rental in Big Sky (3%)
| Rate | 0% state + 3% local = 3% |
|---|---|
| Price before tax | $250.00 |
| Sales tax | $7.50 |
| Total | $257.50 |
Working back: $257.50 ÷ 1.03 = $250.00, so the tax was $7.50. Dividing by 1.03 removes Big Sky's resort tax. Groceries and everyday items in Big Sky are not subject to the resort tax.
Local resort taxes
Montana law lets voters in qualifying resort areas and small resort communities adopt a resort tax. The base rate may not exceed 3%, and voters can approve up to 1% more for infrastructure. The Department of Revenue lists ten resort areas at 3%: Big Sky, Cooke City, Craig, Gardiner, Red Lodge, St. Regis, Virginia City, West Yellowstone, Whitefish and Wolf Creek. The tax applies to lodging, restaurants and bars, destination recreation and goods the community defines as luxuries, not to groceries or everyday necessities. Each community runs its own resort tax.
Lodging tax and buying in Montana
Hotels, motels, campgrounds and vacation rentals charge a lodging facility sales and use tax of 4% plus a 4% use tax, 8% in total, on top of any resort tax. Because Montana has no general sales tax, it is popular with buyers of vehicles, RVs and boats, but residents of other states usually owe tax at home when they register what they bought. For everyday purchases delivered in Montana, online sellers do not charge sales tax.
