Step 2: Choose the transaction type
Select general retail, lodging facility stay, or exempt/non-taxable scenario.
Step 3: Choose or override the resort tax rate

Step 4: Review source checks

How This Calculator Works

Montana's general statewide sales/use/transaction tax is modeled at 0.00%, but that does not mean every checkout estimate is 0%. Lodging, short-term rental vehicles, and local resort tax can still apply.

Lodging mode applies Montana's combined 8.00% lodging facility sales and use tax. Resort tax is modeled as a separate local layer because it depends on the exact resort community, district, ballot authorization, and taxable category.

Rental vehicle mode applies Montana's 4.00% sales tax to qualifying rental-vehicle base charges for rentals of 30 days or less. It does not automatically add excluded charges such as motor fuel, government taxes, or airport concession charges.

In pre-tax mode, the calculator multiplies the taxable base by the combined rate. In tax-included mode, it reverses that formula to estimate the base and tax included in a final total.

Rate assumptions are referenced as of 2026-05-13, and dollar outputs are rounded to cents with decimal arithmetic.

What You Need to Know

Montana is a no-general-sales-tax state, not a no-tax-at-all state

The most common Montana mistake is stopping at the phrase "no sales tax." That is often accurate for ordinary retail purchases, but it does not cover lodging facility taxes, rental vehicle sales tax, local resort taxes, TBID fees, or other selective taxes.

This calculator separates the layers so a user can see whether the estimate is a true 0% retail case, a 4% rental-vehicle case, an 8% lodging case, or a lodging/resort case with an additional local layer.

Montana Rule	Rate	Calculator Treatment
General statewide retail sales/use/transaction tax	0.00%	Montana Revenue resale certificate states Montana does not impose a general sales/use/transaction tax.

Qualified infrastructure add-on	1.00%	Possible additional local layer in qualifying jurisdictions.

Calculator modes

Choose the mode before choosing the resort rate. A standard retail purchase and an overnight lodging stay do not use the same Montana tax logic.

Lodging Facility Stay	8.00%	Resort layer can be added	Montana overnight lodging estimate using the combined 8% lodging facility sales and use tax.

Not automatically modeled

Some Montana charges need a separate source check. This tool calls them out instead of silently guessing.

Tourism Business Improvement District fees, which the Montana Revenue guide says are not the same as lodging or resort tax	Separate rule or local layer	Check the official local or Montana Revenue source before adding it.

Mistake	Why It Matters

Missing taxable lodging fees	The lodging guide says required fees such as cleaning or marketplace service fees can be taxable.

Using outdated resort community counts	The current calculator uses the 10 named communities listed in the Revenue lodging guide.
