What's New for Corporate Taxes:

  • Pay Corporate Tax on MyDORWAY: Pay your Corporate Tax bill on MyDORWAY. No sign in required!
  • CL-1 - Initial Annual Report of Corporations:  The CL-1 Initial Annual Report of Corporations is now a fillable form (in compatible browsers).
  • SC1120T Application for Automatic Extension of Time:  The SC1120T Application for Automatic Extension of Time to File Corporation Tax Return has been modified from the prior year. Line 1 for the tentative tax due should be the net income tax due after deducting: withholding credited to the taxpayer, estimated income tax payments (including last year’s overpayment transferred) and/or income tax credits. Line 2 for the license fee is the net license fee due after deducting any credits against license fees. Line 3 is the total of lines 1 and 2. Do NOT enter less than zero for lines 1 or 2. Always enter your South Carolina Corporate File #, FEIN and the income accounting period end (not a quarter end period).
