Cleaning Business Licensing in South Carolina (2026)

Last updated Q2 2026 · Authored by the Opora Editorial Team · Cited statute: S.C. Code Ann. §33-44 et seq. (LLC Act); §12-36-910(A) (6% sales tax on tangible property); §12-36-910(B)(1) (5% on laundry/dry-cleaning services); §42-1-100 et seq. (Workers' Compensation Act); §42-1-130 (4-employee WC threshold); scbos.sc.gov (SC Business One Stop)

South Carolina has a workers' compensation threshold of four employees — one step below Alabama and Mississippi's five-employee trigger, and higher than most states' one-employee rules. Combined with an E-Verify mandate for businesses with state contracts, a unique sales tax treatment for janitorial services (generally not taxable, with the notable exception of in-shop carpet cleaning), and a right-to-work tradition, South Carolina presents a specific compliance profile for commercial cleaning companies expanding into the Southeast.

Workers' compensation: four-employee threshold and the SC Workers' Compensation Commission

Under the South Carolina Workers' Compensation Act (S.C. Code Ann. §§ 42-1-100 et seq.), employers with four or more employees must maintain workers' compensation insurance. This is the defining number for South Carolina cleaning operations: a company with three employees has no mandatory WC obligation; adding a fourth triggers it. Exceptions include independent contractors, casual employees, certain agricultural workers, licensed real estate agents working on commission, and employers who reported less than $3,000 in payroll the previous year. South Carolina is a competitive (non-monopolistic) state — coverage is purchased from private carriers. The SC Workers' Compensation Commission (WCC), 1333 Main Street, Suite 500, Columbia, SC 29201; telephone (803) 737-5700, administers the system. NCCI class code 9014 applies to commercial janitorial payroll in South Carolina. Injured employees must report injuries to the employer within 90 days of the injury or discovery of the occupational disease. Indemnity benefits in South Carolina are set at two-thirds of the average weekly wage, subject to the state's maximum (approximately $1,035/week as of 2024).

E-Verify requirements for state contractors

South Carolina enacted S.C. Code Ann. § 41-8-20 requiring employers with state government contracts or receiving state financial assistance to enroll in and use the federal E-Verify program to verify the employment eligibility of all new hires. Cleaning companies that service South Carolina state agencies, universities, or government facilities must be enrolled in E-Verify before the contract begins and must verify all new employees hired to work on those contracts. Failure to comply can result in contract termination, debarment, and civil penalties. South Carolina's E-Verify obligation for state contractors is separate from the broader private-sector E-Verify requirements in states like Mississippi. South Carolina private employers not holding state contracts face only the federal I-9 verification requirement. E-Verify enrollment is managed through the DHS portal at e-verify.gov.

Right-to-work: South Carolina Code § 41-7-10

South Carolina is a right-to-work state under S.C. Code Ann. § 41-7-10. No person in South Carolina may be required, as a condition of employment or continuation of employment, to become or remain a member of a labor union or to pay any dues, fees, or other charges to a labor union. South Carolina's right-to-work law has been in effect since 1954 and is among the most consistently enforced in the Southeast. For commercial cleaning companies, the practical implication is a non-union labor market with maximum flexibility in workforce management. The South Carolina Department of Labor, Licensing and Regulation (LLR) enforces right-to-work complaints. LLR is located at Synergy Business Park, Kingstree Building, 110 Centerview Drive, Columbia, SC 29210; telephone (803) 896-4300.

Sales tax treatment of janitorial services

Under South Carolina Code of Regulations § 117-303.2, a person performing janitorial services — washing windows, blinds, floors, rugs, and upholstery in a customer's home or place of business — is not liable for the sales tax measured on gross proceeds. Instead, the janitorial service company pays South Carolina sales tax (6% state rate) on all tangible personal property it purchases and uses in providing those services. This is the "consumer use" model: the cleaning company is treated as the consumer of its supplies, not a retailer. South Carolina's state sales tax rate is 6%, with a maximum local option tax of 3%, producing combined rates up to 9% in some counties. The exception: a business that operates in a dual capacity — both cleaning in customers' facilities AND cleaning at its own shop (e.g., off-site drapery or carpet cleaning) — must collect and remit sales tax on the gross proceeds of its shop-based cleaning operations. The South Carolina Department of Revenue (SCDOR) (P.O. Box 125, Columbia, SC 29214; telephone (803) 898-5000) administers sales tax. Registration for a Retail License ($50 one-time fee) is required before making any taxable sale.

Business registration with the South Carolina Secretary of State

South Carolina cleaning businesses organized as LLCs, corporations, or limited partnerships must file with the South Carolina Secretary of State (Edgar A. Brown Building, 1205 Pendleton Street, Suite 525, Columbia, SC 29201; telephone (803) 734-2158). Domestic LLC formation: $110 filing fee (Articles of Organization). Foreign LLC Certificate of Authority: $110. Annual report for LLCs: $0 (South Carolina eliminated annual report fees for most entities). South Carolina does not have a statewide business license beyond entity registration, but local business licenses — administered by each county and municipality — are required. Uniquely, South Carolina requires a county business license in most of its 46 counties; the fee is based on gross receipts, typically 0.05%–0.15% of gross receipts, with minimum fees of $30–$50. Charleston County and Richland County both require county business licenses in addition to any city licenses within the county.

South Carolina Department of Revenue and sales tax compliance

South Carolina requires all cleaning companies to register as employers with the SCDOR for withholding of South Carolina income tax from employees' wages. The withholding rate follows the employee's withholding certificate; South Carolina's individual income tax rate is a flat 6.2% effective January 1, 2024 (reduced from 7% as part of SC's ongoing rate reduction schedule under the 2022 Tax Act, targeting 6.0% by 2027). Corporate income tax in South Carolina is a flat 5% rate. Cleaning companies must file quarterly withholding returns (SC WH-1601) and annual reconciliation (SC WH-1606) with SCDOR. The SCDOR MyDORWAY portal is the online filing and payment platform for all South Carolina business taxes.

Unemployment insurance: SC Department of Employment and Workforce

The South Carolina Department of Employment and Workforce (DEW) (P.O. Box 995, Columbia, SC 29202; telephone (803) 737-2400) administers unemployment insurance. New employers must register with DEW within 30 days of first payroll by submitting Form UCE-101 (Status Report). South Carolina's taxable wage base is $14,000 per employee per year. New employer UI rates for the cleaning services industry are typically 2.55% for the first several years. Experienced-rated employers range from 0.06% to 5.46%. Quarterly wage reports (Form UCE-101) and tax payments are due the last day of the month following each calendar quarter. Cleaning companies with seasonal fluctuations should maintain careful unemployment claims management, as rate increases from high-UI-claim histories can significantly increase quarterly contributions.

OSHA in South Carolina: federal jurisdiction, private sector

South Carolina operates a state OSHA plan — the South Carolina Department of Labor, Licensing and Regulation (SC LLR), Division of Labor — but this plan covers only state and local government employees. Private-sector cleaning companies in South Carolina are regulated by federal OSHA Region IV (Atlanta; telephone (678) 237-0400). Federal OSHA standards apply in full: Hazard Communication (29 CFR § 1910.1200), Bloodborne Pathogens (29 CFR § 1910.1030), and the general duty clause. The SC LLR Wage and Hour Division also enforces South Carolina wage-and-hour laws, including the SC Payment of Wages Act (S.C. Code Ann. § 41-10-10 et seq.), which requires employers to pay wages at least twice per month and to maintain wage records for 3 years. Violations of the Payment of Wages Act expose employers to treble damages plus attorney's fees — a significant risk for cleaning companies with complex pay schedules.

Local licensing: Charleston and Columbia specifics

The City of Charleston requires a Business License issued by the Revenue Collections Division, with fees calculated as a percentage of gross revenues on a tiered scale (fee schedules are updated annually; cleaning companies typically fall in a service-business category at approximately 0.0045 per dollar of gross receipts). The City of Columbia requires a Business License from the Finance Department, fees similarly based on gross receipts. Greenville and Spartanburg each have city business license requirements with annual renewal cycles. South Carolina's non-uniform local business license system was somewhat standardized by the South Carolina Business License Tax Standardization Act (2020), which established a uniform application form, standardized rate classes, and synchronized renewal dates (May 1 each year for all South Carolina jurisdictions). Cleaning companies with multi-city South Carolina operations benefit from the standardized application process but must still separately file and renew in each jurisdiction.
