South Dakota Payroll Requirements: What Employers Need to Know in 2026

South Dakota has no state income tax. There's nothing to withhold on wages for state income tax purposes, no state withholding registration, and no state income tax returns for your employees. This is one of the reasons South Dakota has attracted a growing number of businesses and remote workers in recent years. If you're setting up payroll in South Dakota for the first time and expecting a state tax registration step, you won't find it. The state's revenue comes primarily from sales tax, not income tax.

South Dakota's minimum wage is $11.20/hr for 2026. The state minimum wage adjusts annually on January 1 each year, tied to the Consumer Price Index, so it increases in most years. Tipped employees can be paid half the standard minimum wage: $5.60/hr, as long as tips bring total compensation to at least $11.20/hr per hour worked. You're responsible for tracking this on a workweek basis and making up any shortfall. South Dakota doesn't allow cities or counties to set higher local minimum wages, so $11.20 applies statewide.

Unemployment insurance in South Dakota is run by the Department of Labor and Regulation (DLR). The SUI taxable wage base is $15,000 per employee for 2026. New employers pay 1.0% for their first two years. Experience-rated employers range from 0.0% to 9.45% depending on their claims history. Quarterly SUI returns are due April 30, July 31, October 31, and January 31. Register for a DLR employer account through the South Dakota Reemployment Assistance online portal before your first payroll. New hire reporting goes to the SD Clearinghouse within 20 days of hire.

South Dakota doesn't have state disability insurance or a paid family and medical leave program. This makes South Dakota one of the simpler states to process payroll in—you're essentially only dealing with federal taxes and state SUI. That said, "simple" doesn't mean "no compliance risks." Wage and hour violations under the federal FLSA still apply: overtime at 1.5x for hours over 40 per week, proper classification of employees vs. contractors, and accurate recordkeeping.

Federal requirements in 2026 are standard. FICA is 7.65% each for employer and employee. The Social Security wage base is $176,100 for 2026. Medicare is 1.45% on all wages with no cap, plus the additional 0.9% Medicare surtax that applies to wages above $200,000 (employee only). FUTA is 0.6% net after credit on the first $7,000. Form 941 is due quarterly. W-2s must be delivered to employees and filed with the SSA by January 31, 2027. Workers' compensation insurance is required but handled through private insurers, not a state fund.
