Cleaning Business Licensing in Missouri (2026)

Last updated Q2 2026 · Authored by the Opora Editorial Team · Cited statute: RSMo §347.010 et seq. (LLC Act); RSMo §351.010 et seq. (General and Business Corporation Law); RSMo §144.010 et seq. (Sales Tax); RSMo §287.010 et seq. (Workers' Compensation Law); RSMo §288.010 et seq. (Employment Security Law)

Missouri's commercial cleaning regulatory environment is shaped by three significant legal developments: the state's right-to-work status (confirmed after a 2018 voter referendum rejected repeal), the repeal of Missouri's prevailing wage law for many public works contracts, and a workers' compensation system administered through the Missouri Department of Labor's Division of Workers' Compensation (DWC). Missouri imposes no state sales tax on janitorial services, which simplifies tax compliance for BSCs compared to neighbors like Kentucky (which taxes janitorial) or Iowa. Missouri's central compliance touchpoints are entity registration, WC coverage at the five-employee threshold, and municipal business licensing in Kansas City and St. Louis.

Missouri does not require a statewide specialty license for commercial cleaning or janitorial businesses. Business formation is handled by the Missouri Secretary of State. LLC Articles of Organization: $50 online; $105 paper. Annual report: $45. Corporations: $58 online. Sole proprietors and general partnerships do not need to register with the Secretary of State, though DBA (fictitious name) registrations cost $7 with the county recorder. All Missouri businesses must register with the Missouri Department of Revenue (MDOR) for a withholding account and, if selling taxable goods, a sales tax license — available free through mytax.mo.gov.

Right-to-Work: History and Current Status

Missouri enacted a right-to-work law in February 2017, signed by Governor Eric Greitens. In August 2018, Missouri voters rejected a referendum to repeal the law, but a circuit court later held that the referendum effectively suspended enforcement. After subsequent litigation and legislative action, Missouri is currently a right-to-work state under Missouri Revised Statutes §290.590, meaning no employee can be required to join a union or pay dues as a condition of employment in any Missouri business.

For BSCs, right-to-work means union security clauses in collective bargaining agreements are unenforceable against Missouri employees. In markets like St. Louis and Kansas City, where SEIU Local 1 and related building service unions have organized some large commercial cleaning accounts, BSCs that have unionized shops are still required to bargain in good faith under the NLRA, but cannot require non-members to pay dues or agency fees. This affects the union organizing calculus and can influence contract pricing in union-pattern accounts.

Workers' Compensation: Five-Employee Threshold

Missouri's Workers' Compensation Law (RSMo §287.010 et seq.) requires coverage for employers with five or more employees in non-construction businesses. Construction industry employers must carry WC from the first employee. For cleaning companies performing routine commercial janitorial services, the five-employee threshold is the standard trigger. However, if a BSC also performs any construction-related cleaning (post-construction cleanup combined with minor finishing work), the one-employee construction threshold may apply.

Missouri's DWC administers workers' compensation claims and self-insurance authorization. Private insurance is available through carriers licensed in Missouri; there is no state fund monopoly. Missouri uses NCCI classification codes. Commercial cleaning is rated under NCCI Class Code 9014. DWC contact: labor.mo.gov/dwc; 3315 West Truman Boulevard, Room 131, P.O. Box 58, Jefferson City, MO 65102-0058; (573) 751-4231 / toll-free (800) 775-2667.

Employers with four or fewer non-construction employees are not legally required to carry WC in Missouri. However, commercial cleaning clients — particularly for facilities with five or more employees on-site — almost universally require proof of WC coverage in contracts. A BSC that operates under the threshold may still need to purchase WC voluntarily to win commercial accounts.

Prevailing Wage Repeal and Public Cleaning Contracts

Missouri repealed its Prevailing Wage Law for most public construction contracts in 2018. Historically, cleaning and janitorial services on public construction projects were subject to prevailing wage requirements in Missouri. The 2018 repeal (House Bill 1729) eliminated prevailing wage requirements for most public works, which affected cleaning contractors performing work on publicly funded construction projects.

However, certain federally funded contracts in Missouri (including GSA-managed federal buildings) remain subject to the Service Contract Act (SCA) under federal law, which sets prevailing wages for service workers including custodial and janitorial staff. BSCs with federal cleaning contracts in Missouri must comply with DOL Wage Determinations under the SCA regardless of the state prevailing wage repeal. The wage determination for St. Louis or Kansas City under SCA can significantly exceed Missouri's $13.75/hour state minimum wage (2025).

Sales Tax: Cleaning Services Not Taxable in Missouri

Missouri does not impose state sales tax on commercial cleaning or janitorial services. Under RSMo §144.020, the Missouri sales tax applies to the retail sale of tangible personal property; services are generally not taxable unless specifically enumerated, and janitorial services are not in Missouri's taxable service list. BSCs need not collect or remit Missouri state sales tax on service invoices.

However, Missouri imposes a 5.3% state sales tax rate (plus local add-ons) on tangible personal property sales. BSCs that sell or resell cleaning products, supplies, or equipment to clients must collect sales tax on those sales. Kansas City imposes an additional 1.125% earnings tax on business gross receipts for businesses with a KCMO business license, which functions differently from a sales tax but applies to cleaning service revenue. St. Louis City imposes a 1% earnings tax. Combined effective rates for businesses operating in Kansas City or St. Louis can reach 10%–11% inclusive of all layers.

Municipal Licensing: Kansas City and St. Louis

Missouri does not have a statewide general business license. However, both major metropolitan areas require local licensing:

• Kansas City: All businesses generating revenue in Kansas City must obtain a KCMO Business License annually through the QuickTax system (bizcare.kcmo.gov). Fee: based on gross receipts. Cleaning businesses must also register for and pay the 1% KCMO Earnings Tax on gross business receipts. License year: January 1–December 31. New businesses: apply within 30 days of first generating revenue in KCMO. Contact: KCMO Business License Section, (816) 513-1120.
• St. Louis City: Requires a City of St. Louis Business License from the Collector of Revenue for businesses operating within city limits. Fee: tiered based on gross receipts; cleaning businesses typically pay $25–$200. The City Earnings Tax of 1% applies to gross business income earned in St. Louis City.
• Other municipalities: Many Missouri cities and counties impose business license requirements; verify with the local city clerk or county assessor.

Independent Contractor Classification

Missouri uses a common-law control test for independent contractor classification. Under RSMo §287.020 (WC) and the Missouri Division of Employment Security's administrative rules, the primary factor is whether the hiring company exercises behavioral and financial control over the worker. Missouri does not apply an ABC test. However, the Missouri Division of Employment Security applies a separate multi-factor test for UI purposes under RSMo §288.034, which weighs: the worker's ability to profit or lose; investment in the business; permanency of the relationship; and skill requirements.

Cleaning companies that use 1099 subcontractors on recurring commercial accounts face audit risk. Missouri DWC and MoDES routinely conduct joint audits of cleaning companies with low reported payroll relative to contract revenue. Misclassification findings result in back UI contributions, WC premium audits, and potential civil penalties under RSMo §288.380.

State Unemployment Insurance

Missouri UI is administered by the Missouri Division of Employment Security (MoDES). Employers register online at labor.mo.gov/des within 30 days of paying $1,500 in wages in any calendar quarter or employing one worker for 20 weeks. New employer UI rate: 2.511% (2024) on the first $11,000 of wages per employee. Experienced employers are rated on a schedule from 0.0% to 5.4%. Missouri also imposes a Federal Unemployment Tax Act (FUTA) credit offset; employers who pay state UI contributions on time receive the full 5.4% FUTA credit. Contact: MoDES, 421 East Dunklin Street, P.O. Box 59, Jefferson City, MO 65104; (573) 751-3215.

Insurance and Bond Requirements

Missouri has no statewide statutory bonding requirement for janitorial businesses. State agency cleaning contracts typically require standard commercial insurance. Missouri's Department of Administration manages state facility services procurement; cleaning contracts for state buildings specify insurance minimums:

• Commercial General Liability: $1,000,000 per occurrence / $2,000,000 aggregate
• Workers' Compensation: Statutory limits per RSMo §287
• Fidelity/Employee Dishonesty Bond: $10,000–$25,000 per employee
• Commercial Auto: $500,000–$1,000,000 combined single limit
