The $16,100 standard deduction leaves $28,900 of taxable income, which puts the last dollar in the 12% federal bracket. Only $16,500 of it is actually taxed at 12% — the income below $12,400 is taxed at the lower rates first, which is why the effective rate lands well under the bracket number. The 12% band runs to $50,400, so a raise of about $21,500 would be needed before any dollar is taxed at 22%.
South Carolina runs a graduated schedule of 2 bands. After $13,636 of state deductions it taxes $31,364, putting the top dollar in the 5.21% band and producing $668 of state tax — 1.48% of gross pay. That is the top band of the state schedule.
Federal income tax of $3,220 on $45,000 of gross pay is 7.16% of the salary, against a 12% marginal bracket — a gap of about 4.8 points. The bracket describes the next dollar earned, not the pay already earned, and quoting the bracket as the tax rate overstates the bill by $2,180 at this salary.
Stacking the 12% federal band, South Carolina's 5.21%, 1.45% Medicare and 6.2% Social Security gives a combined marginal rate of about 24.86%. A $5,000 raise on top of this salary would therefore add roughly $3,757 of take-home pay, not $5,000 — a distinction worth holding on to when comparing offers.

A $45,000 salary in South Carolina leaves an estimated $37,669 per year after federal income tax, Social Security, Medicare, and state income tax. That is about $1,449 per bi-weekly paycheck, assuming a single filer with no pre-tax retirement contributions in the 2026 tax year.

This estimate applies $668 of South Carolina state income tax, plus $0 in modelled employee payroll assessments. Local or municipal taxes are not included.
A statewide 2026 estimate for a single filer, before local taxes, benefit deductions, and W-4 elections. Reviewed through August 9, 2026.
Also not modelled for South Carolina: The $4,930 dependent exemption is South Carolina's tax-year-2025 amount. H.4216 retained the exemption, but S.C. Code §12-6-1140(13) re-indexes it by chained CPI each December 15 and SCDOR has not yet published the 2026 figure, so this is the last published amount rather than a 2026 one. The SCIAD phaseout keys off federal adjusted gross income; this estimate applies it to South Carolina adjusted gross income, which differs for a filer with state-specific modifications. The statutory rounding of the SCIAD reduction down to the next lowest $10 is not applied, so the deduction can be understated by up to $10 inside the phaseout band. SC's EITC, now capped at $200 under H.4216, is not modelled.
