Licenses & Permits in Montana
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.

Montana's cottage food law supports home-based food production. Remote home-based businesses are common in Montana's scattered rural communities.

Common Mistakes to Avoid
- 1
Underestimating construction and site work costs — civil engineering alone can cost $50,000-$150,000
- 2
Not building an unlimited membership program from day one — per-wash revenue models are far less valuable
- 3
Choosing a location without adequate traffic count — 15,000+ cars/day on adjacent road is the minimum for viability
- 4
Skipping water reclamation systems — mandatory in many states and reduces water costs by 50-70%
- 5
Underestimating the importance of equipment maintenance — one conveyor breakdown loses thousands per day
Next Steps to Launch Your Car Wash
- 1
Form your LLC or corporation in Montana — car washes involve significant property and equipment liabilities (filing fee: $70)
- 2
Obtain a Montana water discharge permit from the environmental agency — wastewater from car washing contains oil and chemicals requiring treatment
- 3
Comply with EPA stormwater runoff regulations (NPDES permit) — required for any car wash that discharges water to storm drains
- 4
Obtain a local business license, zoning approval, and sign permits from your Montana municipality
- 5
Secure commercial general liability insurance and property insurance — $3,000–$10,000/year; required for commercial property lease
- 6
Finance or lease commercial car wash equipment (tunnel conveyor, in-bay automatic, or self-serve bays) from manufacturers like Sonny's or WashTec
- 7
Install a water reclamation system to meet Montana environmental requirements and reduce water costs
- 8
Set up a membership subscription program — monthly unlimited wash memberships ($20–$35/month) provide predictable recurring revenue
