Do I charge Montana sales tax on Shopify orders in 2026?

No. Montana has no general state or local sales tax in 2026, so you do not enable MT tax collection in Shopify, and no threshold applies to your Montana-destination orders. 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.

Is Shopify a marketplace facilitator in Montana?

The question does not arise in Montana, because there is no general sales tax for any party to collect. Note that Shopify's core storefront is not a marketplace facilitator anywhere — you are the seller of record in every state where you do owe tax.

Should I still enable MT in my Shopify tax settings?

No. Enabling MT would make Shopify charge your Montana buyers tax that Montana does not impose, which you would then be holding without a return to remit it on. Leave it off.

Does a Montana warehouse create Shopify sales tax duties?

Not in Montana itself — there is no MT sales tax to collect, so inventory stored there triggers no Montana registration. Inventory in other states is a different matter and commonly creates physical nexus there.
