What the SC Payroll Calculator Does

The SC Payroll Calculator helps you:

  • Convert gross wages to net pay (after taxes and deductions).
  • Estimate federal income tax withholding using filing status and allowances (or updated withholding tables).
  • Calculate Social Security (OASDI) and Medicare (FICA) employee and employer taxes.
  • Compute South Carolina state income tax withholding.
  • Account for pre-tax and post-tax deductions (retirement contributions, health insurance, garnishments).
  • Estimate employer payroll taxes (employer share of FICA, FUTA where applicable).
  • Provide payroll cost summaries for budgeting.

It supports hourly, salaried, and contract pay types and can handle pay periods like weekly, biweekly, semimonthly, and monthly.

How to Use the SC Payroll Calculator

  1. Enter Employee Info: Name (optional), filing status (Single, Married filing jointly, Married filing separately, Head of household), and number of dependents or allowances (if using older withholding approach).
  2. Choose Pay Period: Weekly, biweekly, semimonthly, monthly, or annual.
  3. Input Gross Pay: Hourly rate and hours worked (regular + overtime) for hourly employees, or salary divided by pay periods for salaried employees.
  4. Add Pre-tax Deductions: 401(k), health insurance premiums, FSA/HSA contributions (these reduce taxable wages for federal and most state taxes).
  5. Add Post-tax Deductions: Garnishments, Roth contributions, union dues (they don’t reduce taxable wages).
  6. Select Additional Withholding: Any extra federal or state withholding the employee requests.
  7. Calculate: The tool will compute federal withholding, Social Security, Medicare, South Carolina income tax, net pay, and employer taxes.
  8. Review Breakdown: See gross pay, each tax/deduction, net pay, and employer cost summary.

Core Payroll Formulas (Plain Text)

The payroll calculator uses standard tax math and rounding rules for pay-period amounts:

  1. Gross Pay (hourly):
    Gross = (Regular hours × Hourly rate) + (Overtime hours × Hourly rate × Overtime multiplier)
  2. Taxable Wages (after pre-tax deductions):
    Taxable wages = Gross − Pre-tax deductions
  3. Social Security (employee & employer):
    Social Security = Taxable wages × 6.2% (up to annual wage base limit)
  4. Medicare (employee & employer):
    Medicare = Taxable wages × 1.45% (no wage base limit)
    Additional Medicare (employee only) = Taxable wages × 0.9% for wages above threshold (annual)
  5. Federal Income Tax Withholding (approximate):
    Use IRS Publication 15-T methods or percent method: Withholding = Taxable wages × withholding rate (based on filing status & tables) − withholding adjustments
  6. South Carolina State Income Tax Withholding:
    SC withholding uses SC tax tables or percentage method. Withholding = Taxable wages × SC withholding rate (based on SC brackets and allowances)
  7. Net Pay:
    Net pay = Gross − (Employee taxes + Pre-tax deductions + Post-tax deductions + Other withholdings)
  8. Employer Payroll Cost:
    Employer cost = Gross + Employer FICA (6.2% SS + 1.45% Medicare) + FUTA/SUTA estimates + employer-paid benefits

Note: Exact withholding uses IRS and South Carolina tables for the correct tax year and should follow current thresholds and brackets.

Example Calculation (Biweekly Employee)

Scenario: Biweekly paid employee, single, no dependents.

  • Gross pay: $1,200 (biweekly)
  • Pre-tax 401(k): $100 per pay period
  • Social Security rate: 6.2% (employee and employer)
  • Medicare rate: 1.45% (employee and employer)
  • Federal withholding (approx): 12% on taxable wages
  • SC state tax (approx): 4% on taxable wages

Step 1 — Taxable wages:
Taxable wages = 1,200 − 100 = $1,100

Step 2 — Social Security (employee):
SS = 1,100 × 0.062 = $68.20

Step 3 — Medicare (employee):
Medicare = 1,100 × 0.0145 = $15.95

Step 4 — Federal withholding (approx):
Federal = 1,100 × 0.12 = $132.00

Step 5 — South Carolina tax (approx):
SC tax = 1,100 × 0.04 = $44.00

Step 6 — Net pay:
Net = 1,200 − (100 + 68.20 + 15.95 + 132 + 44) = 1,200 − 360.15 = $839.85

Step 7 — Employer payroll taxes:
Employer FICA = 1,100 × (0.062 + 0.0145) = 1,100 × 0.0765 = $84.15 (plus FUTA/SUTA as applicable)

This example gives quick visibility into take-home pay and employer costs.

South Carolina Specific Notes & Considerations

  • State Income Tax: South Carolina has progressive tax rates; check the current year’s SC withholding tables for exact per-period amounts.
  • Reciprocity: SC does not have wage-receiver reciprocity with other states but check local rules for multi-state employees.
  • Local Taxes: South Carolina generally has limited local income taxes, but check municipal requirements.
  • Unemployment Taxes (SUTA): Employer rates vary by experience and employer; FUTA credit reduction may apply in some years.
  • Wage Garnishments: Follow SC and federal rules for priority and limits on disposable earnings.
  • Minimum Wage & Overtime: Federal minimum wage and FLSA overtime rules apply. SC follows federal overtime rules; check state minimum wage updates.
