Paycheck taxes 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.

Bonuses and supplemental wages in South Dakota

South Dakota has no state income tax, so a bonus carries no state supplemental withholding at all — whichever method your employer uses, the state takes nothing. Only federal supplemental withholding applies, which is a flat 22% on supplemental wages up to $1 million.

For the federal half, which this site does model, compare what withholding takes from a bonus against what you actually owe — the 22% flat rate is withholding, not a tax bill, and the difference comes back at filing.
