FAQ
What is the vehicle sales tax in Montana?
Montana charges a state-level rate of 0.00% on vehicle purchases. No local additions apply to vehicles. Trade-in value is NOT deductible — tax applies to full purchase price.
Does Montana give a trade-in tax credit?

What is the title transfer fee in Montana?

How do I calculate out-the-door price in Montana?
Out-the-door = purchase price + (taxable amount × effective rate) + title fee + registration. Taxable amount equals purchase price minus trade-in (where allowed). Effective rate is state plus local. Use the calculator above for an exact figure on your specific purchase.
