South Carolina Code of Regulations — Chapter 117 (Revenue)
S.C. Code Regs. 117-308.6 — Architects
Architects are not considered to be engaged in the business of selling tangible personal property
when they render professional services in the forming of original plans, designs and specifications.
Also considered to be proceeds from the rendition of professional services are charges for the sale of
these original design concepts which have been changed as a result of elevation and/or other
architectural modifications to a customer's specific requirements.
Sales by architects of all reproductions of such plans, designs or specifications, unaltered or
unmodified in any way, are deemed to be subject to the sales or use tax.
