How much do I take home in South Carolina? — short answer first
South Carolina runs a 3-bracket progressive structure (0% / 3% / 6.0%) — but the bracket boundaries are unusually low: the top 6.0% bracket (2026 projected) kicks in at just $17,330 of taxable income for all filing statuses. Effectively, most working adults pay close to the flat 6.0% rate. South Carolina has been phasing the top rate down under Act 87 (2022): 7% in 2022 → 6.4% in 2024 → 6.2% in 2025 → 6.0% projected 2026 → target ~5.0% by 2027. The phase-down depends on revenue triggers. Standard deduction conforms to federal ($14,600 single / $29,200 joint). South Carolina has no local income tax.
The South Carolina take-home pay formula
net_pay = gross − federal_tax − fica − state_tax − local_tax − pre_tax
federal_tax = Σ (federal_bracket × rate) on (gross − std_dev − 401k − hsa)
fica = MIN(wages, $181K) × 6.2% + wages × 1.45% + add'l Medicare
state_tax = Σ (bracket_amount × bracket_rate) // top rate 6.00% in South Carolina
local_tax = 0 // no local payroll tax in South CarolinaThe 2026 take-home calculation for South Carolina stacks four mandatory deductions: federal income tax (7-bracket progressive), FICA (Social Security capped at $181K + uncapped Medicare), South Carolina state income tax (3-bracket progressive, top rate 6.00%). Pre-tax 401(k) and HSA reduce federal taxable income; HSA additionally reduces FICA wages.

How South Carolina taxes payroll in 2026
South Carolina levies a 3-bracket progressive individual income tax under §12-6-510 SC Code. Bracket thresholds are identical for all filing statuses — SC does not differentiate single, joint, or HOH. The 2024 schedule was 0% on the first $3,460 of taxable income; 3% on $3,461-$17,330; and 6.4% above $17,330. Under Act 87 (2022), the top rate phases down each year that state revenue meets growth triggers: 6.2% in 2025, 6.0% projected for 2026, with a target of ~5.0% by 2027. Each annual reduction is conditional — revenue underperformance pauses the schedule. The 0% bottom bracket effectively boosts SC's standard deduction equivalent for lower-income filers — a single filer with $20K of taxable income pays only on the portion above $3,460, dramatically reducing effective rate. Standard deduction conforms to federal ($14,600 single / $29,200 joint, with annual indexing) — this is one of the cleanest tax structures of any Southeastern state. South Carolina has no local income tax — Columbia, Charleston, Greenville, Spartanburg, and Hilton Head all fund services through property tax (effective rate ~0.55% — well below national average) and 6% state sales tax + up to 3% local (Charleston ~8%; Hilton Head ~9%). SC offers a retirement-income deduction of up to $15,000 for filers age 65+ (per filer) and full exemption for Social Security. Combined, SC is moderately retirement-friendly and has been a leading destination for retirees relocating from the Northeast.
South Carolina state income tax brackets (single filer, 2026)
| Taxable income up to | Marginal rate |

How to use this calculator
- Enter your annual gross salary. Pre-tax, what your employer pays before any deductions.
- Pick filing status. Single, married filing jointly, married filing separately, or head of household. Drives both federal and South Carolina brackets.
- Add 401(k) and HSA contributions (optional). Both lower your federal taxable income; HSA also lowers FICA wages.
- Read the verdict. Annual + monthly + bi-weekly take-home, federal + state + local breakdown, and effective tax rate.
Common mistakes
- Confusing gross with adjusted gross. The calculator wants your gross salary — what your employer pays before any pre-tax deductions or contributions. If you enter your W-2 Box 1 (already net of 401k), the math will under-count your tax.
- Forgetting that 401(k) is still subject to FICA. Traditional 401(k) reduces federal income tax but NOT Social Security + Medicare. Only HSA (through payroll) reduces both.
- Using the wrong filing status for state tax. South Carolina uses the same filing status categories as the IRS, but bracket thresholds differ from federal. Pick the status that matches your actual tax filing — not just what gives the best number.
- Ignoring multi-state implications. If you work in South Carolina but live elsewhere (or vice versa), you may owe taxes in both states with a credit between them. This calculator assumes you both live and work in South Carolina.

Payroll terminology — applies to South Carolina
Gross Salary
The headline number from your offer letter, before any deductions. The starting point for every paycheck calculation.
- Lenders, landlords, and benefit calculations use gross. Always confirm whether a quoted figure is gross or net — the gap is typically 25-40% in the US once federal + FICA + state are stacked.
Net Take-Home Pay
What lands in your bank account after federal + FICA + state + local + pre-tax deductions. The number to budget against.
- For South Carolina: gross − federal − FICA − South Carolina state income tax − 401(k) − HSA.
FICA
Federal Insurance Contributions Act — payroll tax funding Social Security (6.2% to $181K) + Medicare (1.45%, no cap). 7.65% combined.
- Additional Medicare 0.9% applies above $200K single / $250K MFJ. Thresholds frozen since 2013, so an increasing share of earners hit it each year. HSA contributions (but NOT 401k) reduce FICA wages.

Marginal Tax Rate
The rate applied to your NEXT dollar of income. Drives the cost of a raise, bonus, or extra 401(k) contribution.
- In South Carolina, your combined marginal rate stacks federal (12-37%) + FICA (1.45-2.35%) + South Carolina state (0.0%-6.0%). A six-figure earner often faces a 35-45% marginal rate.
Effective Tax Rate
Total tax divided by gross income. The actual percentage of your salary that disappears to tax — always lower than marginal.
- Two earners at the same gross can have different effective rates depending on pre-tax contributions. Use effective rate for affordability comparisons; use marginal for raise / bonus decisions.
Standard Deduction
Fixed amount subtracted from gross before federal brackets apply. 2026: $15,750 single · $31,500 MFJ · $23,625 HoH.
- South Carolina's state standard deduction (single) is $14,600 — applied independently before state brackets. Federal and state standard deductions stack; you do not have to itemize on one to claim the other.

Pre-Tax Deductions
Amounts subtracted from gross BEFORE income tax is computed — 401(k), traditional IRA via payroll, HSA, FSA, employer health premiums.
- Reduces federal taxable income dollar-for-dollar. HSA also reduces FICA wages (the 'triple advantage'). Traditional 401(k) reduces federal tax but NOT FICA — Roth 401(k) reduces neither but grows tax-free.
South Carolina State Tax
Progressive 3-bracket state income tax. Top rate 6.00%. Filed on South Carolina Department of Revenue.
- Brackets refresh annually — most state DORs publish updates in Q4 preceding the tax year. South Carolina's structure progresses through 3 brackets, with separate filing-status schedules for MFJ and HoH.
