South Dakota Take-Home Pay Calculator

Q: Does South Dakota have a state income tax?

No. South Dakota's constitution prohibits a personal income tax, so residents pay federal income tax and FICA but nothing to the state on wages, retirement income, or capital gains.

Q: Is South Dakota's retirement income tax-free too?

Yes. All retirement income, including pensions, Social Security, and 401(k)/IRA withdrawals, is free from state tax, since South Dakota doesn't tax any form of personal income.

Q: How does South Dakota fund government without an income tax?

Primarily through sales tax — a 4.2% state rate plus an average 1.91% local add-on — and tourism-related revenue, since South Dakota draws significant visitor traffic to attractions like Mount Rushmore.

Q: Does South Dakota have local city income tax?

No. No South Dakota city or county levies an income tax on wages — the constitutional prohibition applies statewide.

South Dakota has no state income tax, so your paycheck only loses federal income tax and FICA — this calculator shows exactly what that leaves you.

Why the South Dakota paycheck math is simpler

Net pay = Gross − Federal income tax − Social Security − Medicare − Pre-tax deductions
(no state tax line — South Dakota's constitution prohibits one)

South Dakota's constitution bars a personal income tax, and the state has never taxed wages, retirement income, or investment gains. A South Dakota paycheck skips the state-tax line entirely — the same as Texas, Florida, or Wyoming.

Worked example — $80,000, single, biweekly

Taxable after $4,000 pre-tax and $15,000 federal standard deduction: $61,000. Federal tax ≈ $8,334 · Social Security $4,960 · Medicare $1,160.

Annual take-home ≈ $61,546 → about $2,367 per biweekly paycheck (76.9% of gross) — no state tax line to subtract.

A genuinely retiree-friendly state

Because South Dakota taxes no personal income of any kind, retirement income is entirely tax-free at the state level — pensions, Social Security, and 401(k)/IRA withdrawals all pass through without a South Dakota tax bill. Combined with no estate or inheritance tax, South Dakota consistently ranks near the top of state tax-competitiveness rankings.

How South Dakota funds itself instead

South Dakota relies on a moderate sales tax — 4.2% at the state level, averaging about 6.11% combined with local rates — plus meaningful tourism revenue tied to major attractions like Mount Rushmore and the Black Hills. This is a lighter overall tax burden than many other no-income-tax states.
