Purpose of This Guide

Welcome to Montana, the "Treasure State" – one of only five states in the United States that does not impose a general sales tax. For online sellers, this creates a unique situation that both simplifies and complicates tax compliance depending on your business model and customer base.

This guide is designed for e-commerce businesses, marketplace sellers, Amazon FBA sellers,
direct-to-consumer brands, third-party sellers, international shippers, and their accountants or tax professionals who need to understand Montana's tax landscape. While Montana's lack of a general sales tax might seem like a compliance dream, there are important nuances every online seller should understand, particularly regarding specific taxes that do apply and obligations when selling to customers in other states.

Why This Matters

Understanding Montana's tax structure is critical for online sellers for several reasons. First, if
you're based in Montana, you benefit from not having to collect sales tax on most transactions within the state – a significant competitive advantage. However, this doesn't mean you're free from all tax obligations. Montana does impose specific taxes on certain business activities, including lodging facilities, rental vehicles, and businesses operating in designated resort areas.

More importantly, if you're a Montana-based seller shipping products to customers in other
states, you must understand when you trigger economic nexus obligations in those states. Since the 2018 Wayfair decision, most states require out-of-state sellers to collect and remit sales tax once they reach certain sales thresholds, regardless of whether their home state has a sales tax. Additionally, there are potential criminal penalties for mishandling collected sales taxes in states that do impose them, making proper compliance essential for multi-state sellers.
