Sales Tax on Cleaning Services in South Carolina (2025)

Janitorial Labor Sits Outside the Tax Base

South Carolina defines its sales tax around the retail sale of tangible personal property, and under S.C. Code Ann. §12-36-910, that definition does not sweep in general janitorial or cleaning services. South Carolina Revenue Ruling 98-11, issued by the Department of Revenue to address building maintenance and cleaning specifically, confirmed that charges for cleaning commercial or residential space are not subject to the sales and use tax because the transaction is a service, not a sale of goods. A crew running a nightly janitorial route through a Greenville office park does not add a tax line to the labor charge on the monthly invoice.

That said, South Carolina's counties have far more latitude to raise the effective rate than most of its exempt-cleaning peers, because the tax question that matters most in this state usually isn't "is cleaning taxable" but "what county-level rate applies to whatever a cleaning company does buy or sell that is taxable."

How Local-Option Taxes Push the Rate Around

South Carolina's state sales tax rate is 6 percent under S.C. Code Ann. §12-36-910. On top of that base, individual counties can adopt local option sales taxes by referendum for specific purposes: capital projects, school district funding, transportation, or general local option revenue. These add-ons stack, so a county running both a general local-option tax and a capital-projects tax can push the combined rate up by 2 to 3 percentage points above the state floor.

The county-level rate matters to a cleaning contractor mainly on the equipment and supply side, since janitorial labor itself is untaxed regardless of county. Buying a $4,000 auto-scrubber for a Charleston-based crew carries $360 in sales tax at the 9 percent combined rate; the same machine bought for a Greenville crew at the 6 percent rate carries $240. That's a real gap on capital equipment purchases that facilities managers building multi-county budgets should account for.

Worked Example: A Mixed Labor-and-Supply Invoice

Because cleaning labor is exempt but tangible goods resold to a client are not, a typical commercial contract needs to separate the two components clearly.

The contractor collects $64 in sales tax on that $10,000 Columbia-area contract and remits it through the DOR's MyDORWAY portal on whatever filing frequency applies to the account, typically monthly for a business with regular taxable sales volume.

What Trips Up Operators Expanding Across County Lines

• Local-option rates change more often than the state rate. Counties hold referenda periodically to renew or add local-option taxes, so a rate that was accurate last year may not be accurate this year; check the DOR's current rate schedule before quoting a new multi-county contract.
• Exemption applies to the service, not automatically to the whole invoice. If a cleaning company sells or leases equipment, chemicals, or consumables to a client as a distinct transaction rather than as part of the labor charge, that sale is taxable at the applicable combined rate for the delivery location.
• Use tax applies to out-of-state equipment purchases. A South Carolina cleaning company buying floor machines from an out-of-state vendor that doesn't collect SC sales tax owes use tax directly to the Department of Revenue at the same rate that would have applied to an in-state purchase.
• Municipal accommodations and hospitality taxes are separate from sales tax. Cleaning companies servicing hotels or short-term rental properties should not confuse the accommodations tax framework, which taxes lodging, with the sales tax question covered here, which governs the cleaning labor itself.

The department's sales tax section is where local option, capital project, and education capital improvement levies are published by county, and those add to the state rate in ways that vary across the Charleston, Columbia, and Greenville markets a regional contractor typically serves together. Material at the AICPA state and local tax resource center sets out how site-level rate sourcing is evidenced for multi-location service contracts, which is the record an auditor will ask for rather than the rate itself.
