How current is the tax data on this South Carolina paycheck calculator?

Federal brackets are 2026 (IRS Rev. Proc. 2023-34, single filer). FICA wage base is the 2026 $183,600 figure. South Carolina state brackets are 2026 single-filer figures sourced from the South Carolina Department of Revenue or Tax Foundation 2026 individual income tax structure summary.

How does FICA work on the South Carolina paycheck?

FICA = Social Security + Medicare. Social Security is 6.2% of wages up to the 2026 wage base of $183,600 ($10,453 max). Medicare is 1.45% on all wages with no cap. An additional 0.9% Medicare applies to wages above $200,000 for single filers. The FICA stack is identical in all 50 states + DC — South Carolina's state-level rules don't change FICA.

Does South Carolina tax bonuses differently from regular paychecks?

Federal supplemental withholding on bonuses defaults to a flat 22% (or 37% above $1M annual). South Carolina state withholding follows the state's supplemental rules: some states use the regular bracket; others use a flat supplemental rate. Year-end your actual tax liability is identical regardless of withholding method — the difference is whether you owe / refund at filing.

How does South Carolina's top marginal rate compare to other states?

California is the U.S. high water mark at 13.3% top marginal (with mental-health surcharge above $1M). Hawaii sits at 11%, New York 10.9%, Oregon 9.9%, New Jersey 10.75% (above $1M), Minnesota 9.85%, DC 10.75%. South Carolina's top marginal: 0–6.2% (graduated) . The Real Wage Atlas ranks all 51 jurisdictions by effective state-tax burden at the BLS median wage of common occupations.

What's the difference between marginal and effective tax rate in South Carolina?

Marginal rate = the rate applied to your next dollar of income. Effective rate = total tax paid ÷ total gross income. In states with graduated brackets like California or New York, marginal can run 8-10% while effective at $100K is 4-6%. South Carolina's structure: 0–6.2% (graduated) — see the income-tier reference table on this page for effective rate at each tier.

How is a paycheck calculated in South Carolina?

Take-home pay in South Carolina is gross W-2 wages minus federal income tax (2026 single-filer brackets, $15,750 standard deduction), state income tax (0–6.2% (graduated)), and FICA (Social Security 6.2% capped at $183,600 wage base + Medicare 1.45% on all wages, plus 0.9% additional Medicare above $200K single-filer). The page calculator and reference tables apply this stack at common income tiers.

Paycheck After Taxes — South Carolina 2026 (Federal + State + FICA)

TL;DR — South Carolina take-home

Paycheck math in South Carolina layers a graduated state schedule on top of federal brackets and FICA. The first dollars of state taxable income hit the lowest bracket; only the highest dollars hit the top rate. $100K gross → $74,467.

The South Carolina $74,467 take-home translates to $79,663 in real purchasing power because BEA's Regional Price Parity for South Carolina (93.5) sits below the national 100 baseline.

How South Carolina taxes work — 2026 structure

Graduated brackets — effective rate runs below marginal

South Carolina uses a graduated (progressive) state income tax: 0–6.2% (graduated). The first dollars of taxable income hit the lowest bracket; only the highest dollars hit the top rate. Your effective state-tax rate is a weighted average of all brackets your income passes through.

At $100K gross, South Carolina's effective state rate runs noticeably below the top marginal because most of the income is in lower brackets. At $200K, more income clears the top bracket so effective creeps closer to marginal — visible in the reference table's effective-rate column above.

Real take-home — South Carolina cost of living adjusted

Metric	South Carolina value
BEA Regional Price Parity (all-items, 2023)	93.5 (US = 100)
RPP — goods	95.9
RPP — rents	80.5
RPP — services	85.8
$100K gross take-home (nominal)	$74,467
Real take-home (purchasing power)	$79,663

South Carolina sits below the national cost-of-living baseline (RPP 93.5), so a $74,467 nominal take-home expands to $79,663 in real purchasing power — a meaningful arbitrage at this income tier, particularly visible in rents at 80.5.
