Montana Internet Sales Tax

Learn about the Internet sales tax rules for Montana.

Montana, along with Alaska, Delaware, New Hampshire, and Oregon, is one of five states with no state sales tax. Generally speaking, if you are selling goods or products over the Internet to customers located in Montana, sales tax for those customers should be a non-issue.

However, at the federal level, Congress has repeatedly considered legislation that would affect large Internet retailers and how online sales taxes are collected in all states. The most recent form of a proposed federal law is the Marketplace Fairness Act of 2015. As in previous versions, the 2015 Act would allow states to require sellers not physically located in their state to collect taxes on online and catalog sales made to people in their state. Sellers that make $1 million or less in annual sales and have no physical presence in the state would be exempt from this requirement. States would have to meet certain criteria to simplify their sales tax laws and make sales tax collection easier before they could require sellers to collect the tax.

Sales Tax Statements from the Montana DOR

The Montana Department of Revenue (DOR) has a well-written, informative webpage specifically covering sales tax. Among other things, the webpage gives a helpful explanation of the tax situation when a Montana resident buys from an out-of-state Internet seller. In short, with some unlikely exceptions, there is no sales tax involved for sales from out-of-state Internet retailers to Montana consumers.

For States That Do Have Sales Tax

The current default rule throughout the United States is that you must collect sales tax on Internet sales to customers in those states where your business has a physical presence—assuming, of course, that the state involved has a sales tax. The physical presence rule is based on a 1992 United States Supreme Court decisionQuill Corp. v. North Dakota, that addressed the obligations of mail order businesses to collect sales tax on out-of-state sales; the decision has been extended to include online retailers. Generally speaking, a physical presence means:

  • having a warehouse in the state
  • having a store in the state
  • having an office in the state, or
  • having a sales representative in the state.

As you might expect, the corollary to the physical-presence rule is that, if you do not have a physical presence in the state, you generally are not required to collect sales tax for an Internet-based sale to someone in that state.

Because Montana has no state sales tax, these rules are not relevant to sales you make to Montana customers.
