How South Dakota taxes work — 2026 structure

Federal + FICA only — no state income tax

South Dakota levies no state income tax on wage income (no state income tax). Your paycheck stack reduces to federal income tax + FICA only. The federal layer applies the 2026 single-filer brackets after the $15,750 standard deduction. FICA applies regardless of state — Social Security 6.2% to the $183,600 wage base + Medicare 1.45% on all wages, with an additional 0.9% Medicare on wages above $200K.

At the BLS-median income tier of $100K, South Dakota take-home is roughly $5K higher than the same gross paycheck in a 5%-effective state-tax state, and roughly $9K higher than a 9%-effective state. The savings scale linearly with gross — the gap widens to $7K and $13K respectively at $150K.

$100K gross take-home (nominal)	$79,103
