Does Montana charge sales tax on SaaS in 2026?

No. Montana imposes no general sales tax in 2026, so a SaaS subscription sold to a Montana customer carries no Montana sales tax regardless of how the state would otherwise classify software. 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 SaaS taxable in Montana?

No — the taxability question is moot because Montana has no general sales tax to apply to SaaS, downloaded software, or any other product category.

Do I need to register in Montana to sell SaaS?

Not for sales tax. There is no Montana sales tax registration, threshold, or return for a remote SaaS seller. Other business-level taxes can apply if you have people or property in the state, so confirm that separately with the Montana revenue agency.

Do Montana customers count toward my nexus anywhere?

Only toward Montana, which has no threshold — revenue from Montana customers is not counted by any other state. Each state tests only the sales sourced to it, so track your ARR per destination state rather than in aggregate.
