S.C. Code Ann. § 12-54-250 — Authority of Department of Revenue to require payment with immediately available funds debts of $15,000 or more; interest and penalties

(A)(1) The South Carolina Department of Revenue may require, consistent with the cash management policies of the State Treasurer, that a person owing fifteen thousand dollars or more in connection with any return, report, or other document to be filed with the department or a withholding agent making at least twenty-four payments in a year pursuant to Section 12-8-1520(D) pay the tax liability to the State no later than the date the payment is required by law to be made, in funds that are available immediately to the State. "Payment in immediately available funds" means payment by cash to the main office of the department before five o'clock p.m. or by electronic means established by the department, with the approval of the State Treasurer, which ensures the settlement of those funds in the state's account on or before the banking day following the due date of the tax as provided by law.
(2) Initiation of the transfer of funds must occur on or before the due date of the tax. If payment is made by means other than cash and settlement to the state's account does not occur on or before the banking day following the due date of the tax, payment is deemed to occur on the date settlement occurs.
(3) Failure to make timely payment in immediately available funds or failure to provide evidence of payment in a timely manner subjects the taxpayer to penalties and interest as provided by law for delinquent or deficient tax payments.
(B) The department may provide alternative periodic filing and payment dates later than the dates otherwise provided by law for taxes collected by the department in those instances considered to be in the best interests of the State. An alternative date must not be later than the last day of the month in which the tax was otherwise due.
(C) The department may prescribe rules and the State Treasurer banking procedures necessary for the administration of the provisions of this section.
(D) The department may prescribe alternative means other than paper to file returns and reporting documents necessary for the administration of this section.
(E) Reserved
(F)(1) A tax return preparer who prepares one hundred or more returns for a tax period for the same tax year shall submit all returns by electronic means where electronic means are available. Where electronic means are not available to file the return, but 2D barcode is available, the preparer must use 2D barcode. If a taxpayer checks a box on his return indicating a preference that his return is to be filed by another means, the preparer may submit that return by another means.
(2) The department shall include a notice of this requirement in its form instructions and in the forms area of its website.
(3) For the purposes of this subsection, tax return preparer means the business entity and not the individual location or individual completing the return.
(4) If compliance with this section is a substantial financial hardship, a tax return preparer may apply in writing to the department to be exempted from these requirements. The department may grant an exemption for no more than one year at a time.
(5) A person who fails to comply with the provisions of this section may be penalized in an amount to be assessed by the department equal to fifty dollars for each return.
