South Dakota does not tax personal income, so a resident earning South Dakota's median household income of $79,850 owes $0 in South Dakota income tax. Only federal income tax and FICA are withheld from wages.

Based on 2026 South Dakota rules and 2026 federal rules, with the standard deduction and no other adjustments. Median income is the 2024 Census figure.

Income tax in South Dakota

South Dakota funds itself through consumption taxes with a distinctly seasonal shape. The state sales and use tax rate is 4.2%, applied to the gross receipts of retail sales, leases and rentals of tangible personal property, products transferred electronically, and services. Layered on top is a 1.5% tourism tax covering hotels and lodging, campgrounds, motor vehicle and recreational equipment rentals, recreational services, spectator events, and visitor attractions — and for so-called visitor-intensive businesses it applies only during June, July, August, and September. The Department of Revenue even publishes dedicated tax applications, licensing instructions, and municipal tax rates just for the Sturgis Motorcycle Rally, which is a fair indication of how much of the state's revenue arrives with out-of-state visitors rather than resident paychecks.

South Dakota income tax structure (2026)

South Dakota has no state income tax. Wages, salaries, and self-employment income are untaxed at the state level — only federal income tax and FICA come out of your paycheck.

Common questions

Do I file a South Dakota income tax return?
Not for wage income. South Dakota has no individual income tax for 2026, so your only income tax return is the federal one, and a $79,850 income — South Dakota's median — owes the state $0.
How much income tax is due on the median South Dakota income?
On South Dakota's median household income of $79,850 (2024 Census figure), a single filer owes about $8,737 in federal income tax and $0 to South Dakota. Adding $6,109 of Social Security and Medicare leaves roughly $65,004.
What taxes do I still pay in South Dakota?
Federal income tax, Social Security (6.2% up to the wage base) and Medicare (1.45%) still apply — together about $14,846 a year at South Dakota's $79,850 median income. South Dakota raises its own revenue through sales and use taxes.
Why is take-home pay higher in South Dakota?
Only because the state line is zero — federal tax and FICA are identical everywhere. At South Dakota's $79,850 median income, the typical income-taxing state would take about $3,150 more per year that South Dakota residents keep.
