Is SaaS taxable in Montana?

SaaS taxability varies wildly by state. Montana's general sales tax rate is 0.00%, but whether software-as-a-service is subject to that rate depends on the state's definition of “taxable service” or “canned software” and on whether it's delivered to an in-state user.

Regardless of SaaS taxability, the economic nexus threshold of the state's economic nexus rules (pending data verification) applies. If you exceed it on subscription revenue, you register; from there the question becomes what you tax, not whether.

Practical steps for SaaS companies

Track Montana-sourced ARR (use billing country or IP geolocation).
Determine taxability: consult a CPA or use an automated service that maintains taxability rules by state.
Register once you cross threshold, even if SaaS is currently non-taxable — rules change.
Integrate tax calculation into your billing platform (Stripe Tax, Quaderno, Chargebee with Avalara).

SaaS-specific traps to avoid in Montana

Treating SaaS and “canned software” the same way. Many states distinguish between cloud-hosted SaaS and prepackaged downloaded software, with different tax treatments. Check Montana's specific definitions before assuming your product falls in either bucket.
Bundling non-taxable SaaS with taxable services (training, consulting, hosting). Bundle-pricing can make the whole charge taxable if the taxable component isn't separately stated.
Ignoring use-tax obligations. If your customers are in Montana and your SaaS isn't taxable there, the customer may still owe use tax — a detail that can trip up B2B SaaS during audits.

Montana nexus note

Montana has no general state or local sales tax. Sellers shipping to Montana customers do not need to register or collect. Exceptions: certain resort-area local option taxes and accommodations/rental car taxes apply to specific industries.
