When should your
business collect Sales
Tax in Montana?

If your business operates in Montana and sells goods or services, you generally do not collect sales tax at the state level because Montana has no general state sales tax. However, you must monitor whether you have a nexus (physical or economic) in a municipality or resort community that has opted to impose a local sales or resort tax. If you do have nexus in such an area and you are making sales of items or services taxable under that local tax, then you must register, collect the applicable local tax, remit it, and file returns according to that locality’s schedule.

Montana physical sales tax nexus.

Physical nexus in Montana is determined by each local jurisdiction

Sales tax physical nexus checklist for Montana

The following conditions might establish a physical nexus in Montana:

  • Maintaining a physical location (office/store) in the municipality or resort community.
  • Having employees present in that municipality or resort community.
  • Owning or leasing property (inventory, equipment) in the municipality or resort community.
  • Operating a business through agents, salespersons, or representatives in the locality (by inference from typical nexus rules).
  • Hosting inventory or fulfillment activities in that locality.

Which services are taxable in Montana

  • Accommodation (e.g., hotel stays)
  • Rental of personal property
  • Guided tours or recreational services

In local jurisdictions where a resort or local option sales tax is imposed, services may be subject to tax.

Montana sales tax information:

Since Montana has no statewide rate, you simply apply the specific rate of the jurisdiction that does tax your product or service. Take the total sale price and multiply it by that local rate. The result is the exact amount of tax you must charge and later remit.

Montana has no general statewide sales tax, but it does apply an 8% lodging tax on accommodations and allows designated resort communities to impose a 3% local resort or local option tax on certain goods and services such as lodging, restaurants and luxuries.

If your business must collect tax (such as the lodging facility tax), you register through the state’s TransAction Portal by selecting “Business” then “Register for a New Tax Account.” After submitting the required info, the Department issues a welcome letter and permit number. For local resort taxes, you register directly with the locality, typically through local business registration and any required tax permit or bond.

Confirm whether your business is in a taxing jurisdiction and that your product or service is taxable, identify the correct rate, add the tax to each taxable sale, keep detailed records of sales and tax collected, and remit the tax with the required return by the due date.

Sales Tax return due dates explained.

For taxes like the lodging facility tax, returns and payments must be filed by the last day of the month following the end of each calendar quarter.

Quarterly Filing Deadlines

  • Quarter 1 (Jan‐Mar): April 30 or local equivalent
  • Quarter 2 (Apr‐Jun): July 31 or local equivalent
  • Quarter 3 (Jul‐Sep): October 31 or local equivalent
  • Quarter 4 (Oct‐Dec): January 31 or local equivalent

FAQs

No - Montana does not impose a general statewide sales tax on all goods and services. The base rate is effectively 0%. However, certain local jurisdictions (resort communities) and specific industries (e.g., lodging) have taxes you must check.

If I sell digital services (SaaS) to customers in Montana, do I need to collect tax? Since Montana’s general sales tax is absent, SaaS is generally not taxed statewide. But if you have nexus in a local area that has a resort tax and the local rules treat digital services as taxable, then yes you may need to collect local tax. You must check local rules.

If you have nexus and are making sales of taxable items or services in that community, failing to register may result in penalties, interest, and you may still be liable for unpaid tax. Local jurisdictions often require bonds or other security (for example Red Lodge requires a $500 bond) as part of registration.
