Sales tax deduction in Montana

Varies

Is Sales Tax Deductible in Montana?

Short answer: Rarely: Montana has no statewide sales tax, so deducting state income tax is almost always bigger. No general sales tax; designated resort communities (e.g., Big Sky, Whitefish, West Yellowstone) may levy a local resort tax of up to 3%, plus up to 1% more for infrastructure.

Use the IRS Sales Tax Deduction Calculator or your receipts, add sales tax paid on a car, boat, or home-building materials, and stay within the $40,400 SALT cap (Schedule A line 5a).

Records to keep: Keep your state return, W-2s and 1099s (1099-R, SSA-1099), and any state credit worksheets. Check your state revenue department's current-year instructions before you file.
