Licenses & Permits in Missouri

General Business License

Missouri does not have a statewide general business license. Businesses must register their entity with the Missouri Secretary of State and register with the Missouri Department of Revenue for sales and use tax purposes. Missouri cities and counties may require local business licenses — Kansas City, St. Louis, and Springfield each have their own licensing programs. Note that St. Louis City and St. Louis County are separate political entities with different licensing requirements.

Common Mistakes to Avoid

1
Underestimating material costs and change order frequency
2
No lien waiver process protecting cash flow
3
Subcontractors without proof of insurance
4
Poor project scheduling causing costly delays
5
No written contracts with payment schedules

Next Steps to Launch Your General Contracting Business

1
Form your LLC or corporation in Missouri — general contractors carry significant liability for subcontractor work and project defects (filing fee: $50)
2
Obtain your Missouri general contractor license — requires experience documentation, exam, and financial statements in most states
3
Obtain a contractor surety bond ($10,000–$50,000) and general liability insurance ($2,500–$8,000/year) — required for most permits and contracts
4
Complete OSHA 30-Hour Construction Safety training — required by most commercial project owners and insurance carriers
5
Register with Missouri Contractor State License Board or equivalent regulatory agency and maintain license with required continuing education
6
Build a subcontractor network: licensed plumbers, electricians, HVAC techs, and framers — GCs depend on reliable subs for project quality
7
Create a construction contract template using AIA or AGC contract forms covering scope, payment schedule, change orders, and warranty
8
Get workers' compensation insurance before hiring any employees or subcontractors — Missouri requires WC for all construction workers

Frequently Asked Questions

Starting a general contracting business typically requires $20,000–$55,000, covering contractor licensing ($500–$2,000), surety bond, liability insurance ($1,500–$4,000/year), workers comp, a reliable work vehicle, tools, and working capital. Materials for active projects can require significant additional capital.

Most states require general contractors to be licensed. Requirements vary — some require passing a trade exam, others require proof of experience and financial responsibility. California, Florida, and Texas have strict requirements. Check your state contractor licensing board for specific requirements.

GCs earn 10–25% markup on subcontractor labor and materials. On a $200,000 remodel, a 15% GC margin generates $30,000 gross. After overhead, net margins average 8–15%. Larger commercial projects have lower margins but higher volume; custom residential work often commands 15–20%.

If subcontractors are true independent contractors with their own workers comp, the GC may be exempt. But if a subcontractor lacks coverage, the GC's policy may pay their claims. Always verify subcontractor insurance certificates — liability flows to the GC in most states.
