General Business License
Montana does not have a statewide general business license. Businesses must register their entity with the Montana Secretary of State and register with the Montana Department of Revenue for withholding taxes. Montana has no sales tax, which simplifies business registration. Some Montana cities and counties require local business licenses. The state's outdoor economy and tourism industry influence many licensing requirements.

Next Steps to Launch Your Marketing Agency

- 2
Obtain a business license in Montana and any local municipality where your office is located
- 3
Get professional liability (E&O) insurance — $800–$3,000/year; clients often require proof before signing retainer agreements
- 4
Set up agency-grade project management — Basecamp, Notion, or Monday.com for client project tracking and collaboration
- 5
Create a client onboarding process: intake questionnaire, brand audit, kickoff agenda, and 90-day plan template
- 6
Build a case study portfolio with 2-3 documented results — even pro bono work with measurable ROI builds credibility

Set up your invoicing and retainer billing system — FreshBooks or QuickBooks with automatic recurring invoices
