Due Dates:

 Returns are required to be filed no less than once each calendar year, in accordance with SC Code Section 12-37-970. Returns are normally due on or before the last day of the fourth month following the taxpayer’s accounting closing date used for income tax purposes.

The following exceptions apply:
  • Initial return: The initial return is required to be filed for the first calendar year in business based on the taxpayer’s accounting closing date or December 31, whichever comes first. Example: A taxpayer who starts operation in July, after their June accounting closing date, should file based on assets as of December 31.
  • Change in account closing date: When a taxpayer changes their accounting closing date, within a calendar year, they must file a return for each accounting closing date. The SCDOR will determine the assessment from each return and use the highest assessment.
  • Property sold after the seller's account closing date: A return is required by the seller, based on the seller's accounting closing date. The purchaser is not required to file a return as of the purchaser's accounting closing date during the calendar year of the sale.
  • Property sold before the seller's account closing date: An initial return is required by the purchaser, based on the purchaser's accounting closing date or December 31, whichever comes first, after the purchase of the property.
