South Carolina taxes wage income using progressive brackets with a top marginal rate up to about 6.4%. Pre-tax traditional 401k deferrals generally reduce your South Carolina taxable income in the year of contribution, similar to federal treatment. Distributions from traditional 401k accounts are generally taxable in South Carolina in retirement. Roth 401k tradeoffs depend on federal and state rules for contributions and qualified distributions — consult a tax professional for your situation.

With progressive South Carolina rates up to about 6.4%, traditional 401k deferrals reduce current state and federal taxable income. Roth 401k or Roth IRA contributions use after-tax dollars but can yield federally tax-free qualified withdrawals; weigh that against your expected retirement tax picture. The 2026 Roth IRA contribution limit is $7,500 ($8,600 if age 50+), with income phase-outs. Typical employer matches are often 3–6% when you defer enough.
The 401k employee contribution limit in 2026 is $24,500 for all US workers including South Carolina residents. Workers aged 50–59 and 64+ can contribute an additional $8,000 catch-up for a total of $32,500. Workers aged 60–63 can contribute an additional $11,250 for a total of $35,750. Combined employee and employer contributions can reach up to $72,000 in 2026 (plus catch-ups where allowed).
South Carolina has a progressive state income tax with a top marginal rate up to about 6.4%. Traditional 401k salary deferrals generally reduce both federal and South Carolina taxable income, so you typically save South Carolina tax on amounts deferred now and pay South Carolina tax on traditional 401k withdrawals in retirement.
Many South Carolina employers match about 3% to 6% of salary when you defer enough to earn the full match. Always capture the full match if you can. The combined employee-employer limit is $72,000 in 2026 before age-based catch-ups.
Traditional 401k lowers federal and generally South Carolina taxable income now at your marginal rates (progressive brackets up to about 6.4%). Roth 401k uses after-tax dollars but can provide federally tax-free qualified withdrawals; confirm South Carolina treatment of Roth contributions and distributions with a tax advisor.
Total contributions from you and your employer generally cannot exceed $72,000 in 2026 (plus allowed catch-ups). Employer matching dollars count toward that cap.
Pre-tax traditional 401k deferrals usually reduce your South Carolina taxable wages (they are generally excluded from state taxable income similar to federal), rather than a separate line-item deduction. Roth 401k deferrals do not reduce current taxable income.
