How does Amazon FBA sales tax work in Montana in 2026?

It does not apply. Montana imposes no general sales tax in 2026, so neither Amazon nor you collect sales tax on FBA or MFN orders delivered to Montana buyers, and there is no Montana marketplace facilitator threshold to track. 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.

Does Amazon FBA inventory in Montana create physical nexus?

Inventory stored in a state is the classic physical-presence trigger, but in Montana it triggers no sales-tax duty because Montana has no general sales tax to register for or collect. Inventory Amazon moves to fulfilment centres in other states is where this question actually bites — pull your Inventory Event Detail report and check which states hold your units.

Do I need to register in Montana as an Amazon seller?

Not for sales tax. Montana has no general sales tax registration for remote or marketplace sellers. Other business-level taxes can apply to in-state activity, so confirm with the Montana revenue agency if you have staff, an office, or a warehouse there.

Do my Montana Amazon sales count toward any threshold?

Not toward a Montana one, because Montana has none. They also do not count toward other states' thresholds — each state tests only the sales delivered into that state.
