What is Montana's e-commerce sales tax in 2026?

There is none. Montana levies no general state or local sales tax in 2026, so an out-of-state store shipping to Montana buyers has no economic nexus threshold to cross, no rate to charge, and no Montana sales tax return to file. You still owe sales tax in states that do impose one, so test each destination state against its own threshold rather than against Montana's.

Do I collect sales tax on every Montana order?

No. Because Montana has no general sales tax, you collect nothing on Montana-destination orders regardless of your sales volume or whether you have people, an office, or inventory in the state.

Do I need to register with Montana to sell online?

Not for sales tax — Montana has no general sales tax to register for. Other business-level taxes can still apply to in-state activity, so confirm what your presence triggers with the Montana revenue agency before assuming you owe nothing at all.

Does shipping from Montana make my sales tax-free?

No. Where you ship from does not decide the tax; the destination state does. Sales you deliver into other states are tested against those states' thresholds and rates, so a Montana-based store can owe sales tax in a dozen other states.
