Is SaaS Taxable in South Carolina?
Short answer: Generally, yes, when a customer pays to access a provider’s website and use software hosted there. South Carolina treats this application service provider (ASP) model as a taxable communications service. The statewide sales tax rate is **6%**, and local tax may apply.
Why does South Carolina treat SaaS as taxable?
South Carolina’s definition of tangible personal property includes certain services and intangibles that the state taxes, including communications. That definition does not make every online transaction taxable on its own. The tax treatment depends on what the customer pays to receive.
In Revenue Ruling #03-5, the Department of Revenue considered a charge that allowed a customer to access an ASP’s website and use software on that site. The department concluded that the charge was similar to a taxable database access transmission service. Its 2025 Sales and Use Tax Manual continues to list application service providers among taxable database access services and identifies ASP offerings as SaaS.
Why can an electronic software sale have a different result?
The ruling distinguishes accessing software hosted by a provider from buying software delivered electronically to the customer.
A customer who pays to use software on an ASP’s website is buying the type of access the department held taxable. By contrast, the ruling says a standalone software sale delivered entirely by electronic means is not subject to sales and use tax when no part of the software is delivered through tangible media.
Consider two examples. A business pays a monthly fee to log in to a vendor’s platform and use an application there. That resembles the taxable ASP transaction. Another business buys a copy of software that the seller transfers entirely electronically, with no disk or other tangible delivery. That transaction calls for analysis under the electronic-delivery rule. Both involve the internet, but they do not provide the customer with the same thing.
What about data processing services?
South Carolina law excludes charges for qualifying data processing from the relevant sales and use tax provisions. Data processing can involve manipulating information supplied by a customer, including computing, sorting, storing, or retrieving it. Revenue Ruling #03-5 explains that the ASP in its example was charging for access to its website and software rather than for qualifying data processing.
The distinction rests on the transaction’s substance. Calling a product “data processing,” “cloud software,” or “SaaS” does not determine its tax treatment. An offering that combines hosted software access with other services needs a closer review of its functions, contract, and charges.
What should a SaaS seller review?
Start with the customer agreement and invoice:
- Does the customer use software on the provider’s site, or receive software through an electronic transfer?
- Does the package include physical media, hardware, or other products?
- Can the charges for different products or services be identified from the records?
Once a charge is classified, the seller must determine the applicable rate and collection obligation. South Carolina’s sales tax guidance lists the 6% state rate and explains that local sales taxes may also apply.
