How to start a cleaning business in Missouri is a question more entrepreneurs are asking as the state continues to offer affordable startup costs, strong local demand, and business-friendly regulations. With growing residential neighbourhoods and thriving commercial hubs in St. Louis, Kansas City, Springfield, and Columbia, Missouri presents a profitable opportunity for anyone looking to launch or scale a cleaning company in 2026.
However, while Missouri is welcoming to small businesses, it is not rule-free. Sales tax on cleaning services, local licensing requirements, and compliance deadlines can easily catch new business owners off guard if they are not prepared.
This ultra-local guide explains how to start a cleaning business in Missouri, avoid costly mistakes, and build a compliant, profitable operation from day one.

Step 1: Missouri Sales Tax on Cleaning Services
Many new owners are shocked to learn that cleaning services are taxable in Missouri.
The Rule
Missouri considers janitorial and cleaning services taxable, particularly commercial cleaning. Residential cleaning may still be taxable depending on how services are billed and structured.
The Action
Before your first job, you must register for a Missouri Sales Tax License with the Missouri Department of Revenue.
The Rate
Missouri sales tax includes:
- 4.225% state tax
- Local city & county tax (often bringing totals to 7%–9%)
Example:
If you charge $150 for a cleaning job in St. Louis with an 8.7% combined rate, the client pays $163.05, and $13.05 must be remitted to the state.
Warning
If you fail to collect sales tax, Missouri will still demand payment, plus interest and penalties — even if the money came out of your own pocket.
Step 2: Forming Your Missouri LLC
Creating an LLC protects your personal assets and builds credibility with clients.
1. File Articles of Organization
- Cost: $50 online
- Where: Missouri Secretary of State
2. Register for Taxes
After forming your LLC, register with:
- Missouri Department of Revenue (sales tax & withholding)
- IRS (for your EIN)
Step 3: Business Licenses & Local Rules
Missouri does not issue a statewide cleaning license — but local governments do.
City & County Business Licenses
Depending on where you operate, you may need:
- A city business license (St. Louis, Kansas City, Springfield)
- A county license if operating outside city limits
DBA (Fictitious Name)
If your business name doesn’t include your legal LLC name, file a Fictitious Name Registration with the Secretary of State.
Step 4: Hiring Employees in Missouri
Employer Requirements
If you hire cleaners, you must:
- Register for Missouri withholding tax
- Display required labor posters
- Follow Missouri minimum wage laws
Workers’ Compensation
Missouri requires Workers’ Comp insurance once you have employees. Many commercial clients will also demand proof before signing contracts.
Step 5: Insurance for Missouri Cleaning Businesses
General Liability Insurance
Essential coverage for:
- Property damage
- Accidental breakage
- Slip-and-fall claims
Bonding (Optional but Valuable)
Many Missouri commercial contracts prefer bonded cleaning companies — especially medical offices and government facilities.
Step 6: Managing Missouri Geography Efficiently
Missouri may look compact, but driving time kills profit.
St. Louis & Kansas City Reality
- Crossing metro areas can take 60–90 minutes
- Traffic + fuel costs add up fast
Smart Strategy
- Choose one metro zone
- Stack jobs by ZIP code
- Avoid cross-city scheduling
