Developers that want to become a certified vendor

The process for becoming a new certified vendor in our state is temporarily suspended until January 2027. Please contact our office at XML@dor.sc.gov for additional information.
During this time, filers must use an existing certified developer listed above or file their returns manually on MyDORWAY, our free online tax portal.

Sales XML reporting requirements

Below are some reporting requirements you must follow to successfully upload your XML returns.

You must use a valid 9-digit retail license/file number assigned by the SCDOR in the XML file for a Sales, Use, Accommodations, or Max Tax account.
Each return in the XML file must have a unique retail license file number.
ST-389 Local Taxes must be valid for the period filed (expired Local Taxes will not be allowed).
Net taxable sales for each local tax type cannot exceed total gross proceeds.
Sales Tax Holiday deduction is only valid for the month of August. (Quarterly and Annual filers may also claim this deduction if applicable. Quarterly filers will report this deduction on their Q3 return)
XML files cannot be processed for periods with a return already on file for the account.
