What this figure does not include

  • Because South Carolina begins with federal taxable income, no state standard deduction is carried in this file; the federal standard deduction must be applied upstream.
  • The 44% net capital gain deduction, the two-wage-earner credit and the retirement/age deductions are not modelled.
  • Active trade or business income of a pass-through may instead be taxed at a flat 3% under S.C. Code Ann. Sec. 12-6-545; that election is not modelled.
