Does this estimate change if I'm married or have dependents?
This calculator uses single-filer figures only (v1 scope). Married filing jointly typically uses different federal and South Carolina state brackets and a larger standard deduction — your actual take-home pay will differ. Dependents can also reduce federal withholding via the W-4. Check South Carolina Department of Revenue's married-filing-jointly tables for a precise figure.
Methodology & Source
South Carolina state tax figures sourced from South Carolina Department of Revenue (https://dor.sc.gov/), citing H.4216 (signed 2026-03-30) — 2-bracket overhaul, 1.99% under $30,000 / 5.21% above, decoupling from the federal standard deduction. Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). South Carolina's married-filing-jointly and head-of-household figures are not yet independently verified and currently fall back to single-filer brackets — see the caveat in the formula section above.
Bonus federal withholding uses the flat supplemental-wage rate (22%, 37% above $1,000,000 cumulative supplemental wages/year), per IRS Publication 15 (Circular E), Employer's Tax Guide, 2026 edition — the alternative "aggregate method" is not modeled.
This is an estimate based on standard single-filer federal, FICA, and SC state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, and other factors. H.4216 replaces the federal standard deduction with a new "South Carolina Income Adjusted Deduction" (SCIAD) of $15,000 for single filers — but that amount phases out on a sliding scale between $40,000 and $95,000 of federal AGI (numerator = AGI over $40,000, denominator = $55,000). This estimate applies the full $15,000 regardless of income, which understates SC tax for filers in that phase-out band. Verify at dor.sc.gov for high-precision use.
