How South Carolina State Income Tax Works

South Carolina uses a three-bracket progressive system with rates of 0%, 3%, and 6% in 2026. The state has been gradually reducing its top rate — from 7% (2021) to 6.5% (2022) to 6.0% (current 2026 cap). The SC General Assembly has targeted further reductions contingent on state revenue performance.

South Carolina calculates state income tax as follows:

1. Start with South Carolina taxable income — generally federal AGI, adjusted for SC-specific items.
2. Subtract the SC standard deduction — $14,600 (single) or $29,200 (married jointly) for 2026, conforming to the federal standard deduction.
3. Apply brackets — 0% on the first $3,640, 3% from $3,641 to $18,230, and 6% on SC taxable income above $18,230.

How the Large Standard Deduction Affects Your Tax

Because South Carolina's standard deduction ($14,600 single) is large relative to the bracket thresholds ($3,640 and $18,230), most moderate-income earners see a very different picture from the bracket table alone. After the $14,600 deduction, a single filer earning $65,000 has SC taxable income of only $50,400 — nearly all of which is taxed at 6%. The 0% bracket covers only the first $3,640, and the 3% bracket applies only from $3,641–$18,230. Effectively, most wage earners pay close to 6% on the bulk of their SC taxable income.

Federal Income Tax — Progressive Brackets

On top of South Carolina state tax, every SC worker owes federal income tax at rates from 10% to 37% in 2026.

Step-by-Step Example — $75,000 Single Filer in South Carolina (2026)

1. Gross annual pay: $75,000
2. Federal taxable income: $75,000 − $16,100 = $58,900. Federal tax ≈ $8,800.
3. SC taxable income: $75,000 − $14,600 = $60,400. SC tax: $0 (0% × $3,640) + $438 (3% × $14,590) + $2,531 (6% × $42,170) = $2,969.
4. FICA: $75,000 × 7.65% = $5,738.
5. Net take-home: ~$57,493/year (~$2,211 biweekly).

FICA Taxes — Social Security and Medicare

• Social Security: 6.2% on wages up to $176,100 (2025) or $184,500 (2026). No further withholding once you cross the wage base for the year.
• Medicare: 1.45% on all wages with no cap. Additional 0.9% Medicare surtax on wages above $200,000 single / $250,000 MFJ.
• Employer match: your employer matches Social Security and base Medicare; the Additional Medicare surtax is employee-only.

South Carolina vs. Neighboring States

• vs. North Carolina:NC has a flat 4.5% rate with a $10,750 standard deduction (single). At $75,000, an NC single filer pays roughly $2,990 in state tax. South Carolina is similar for this income level, but SC's larger standard deduction makes it cheaper for higher incomes while NC's lower flat rate is better for moderate incomes.
• vs. Georgia:GA uses a flat 5.49% rate with a $24,000 standard deduction (single). A $75,000 GA earner pays about $2,801 in state tax — slightly less than SC. Georgia's deduction is different but the rates are comparable.
• vs. Florida: Florida has no state income tax. A $75,000 SC earner pays about $2,969 in state tax that a Florida resident avoids entirely.
• vs. Virginia: Virginia uses progressive brackets topping at 5.75%. At $75,000, a VA filer pays roughly $3,200 in state tax — somewhat more than SC.

How to Maximize Your South Carolina Take-Home Pay

• Max your 401(k) — reduces both federal and SC state taxable income. A $20,000 contribution at the 22% federal + 6% SC rate saves roughly $5,600/year.
• Use an HSA — South Carolina honors HSA contributions as pre-tax. $4,300 individual / $8,550 family in 2026; FICA savings apply through payroll.
• Enroll in Dependent Care FSA — up to $5,000 pre-tax for qualifying childcare reduces both federal and SC taxable wages.
• SC Dependent Exemption — South Carolina allows an additional exemption for dependents. This can further reduce your SC taxable income beyond the standard deduction.
• File South Carolina SC W-4 — South Carolina uses its own withholding form. Update it whenever your filing status or deductions change to ensure accurate state withholding.
