Montana state guide
Montana vehicle purchase tax
Montana has no statewide general sales tax, so a standard vehicle purchase has no buyer sales-tax calculation.
Title and registration
The calculator includes the current $12 light-vehicle title fee and age-based state registration rate plus the 3% administrative fee. County option tax, plates and permanent-registration choices can increase the total.
Worked example
A vehicle five to ten years old uses Montana’s $87 state registration rate before the 3% administrative fee and county option tax.
