At-will employment doctrine
South Dakota follows the at-will employment doctrine. An employment relationship with no specified term may be terminated by either the employer or the employee at any time, for any reason (or no reason), on notice to the other party. The only constraint is that the termination must not violate a statutory exception — such as anti-discrimination laws, retaliation protections, or other employment statutes that carve out specific prohibited grounds for discharge.

Final paycheck timing — next regular payday rule
South Dakota requires employers to pay all unpaid wages and compensation to separated employees no later than the next regular stated pay day for which those hours would have normally been paid. This timing requirement applies uniformly to both involuntary terminations (employer-initiated separations) and voluntary quits (employee-initiated resignations). The statute does not distinguish between the two categories or impose an accelerated deadline for either.
Employer property exception. The statute permits employers to delay the final paycheck beyond the next regular payday if the employee has not yet returned all employer property in the employee's possession. Under S.D. Codified Laws § 60-11-10, the final wages are due "as soon thereafter as the employee returns to the employer all property of the employer in the employee's possession." This provision gives the employer a conditional right to withhold the final paycheck until the return of property such as laptops, uniforms, keys, tools, or company vehicles. The South Dakota Department of Labor and Regulation confirms this interpretation in its official guidance, stating that "the law does allow an employer to withhold the final paycheck until the employee returns any property that belongs to the employer."
The statute does not specify whether the employer may withhold the entire final paycheck or only an amount proportional to the value of the unreturned property. The plain text permits withholding the full paycheck until return of all employer property, though employers should be aware that federal wage-and-hour law (FLSA) generally prohibits deductions from final wages that would reduce total compensation below the federal minimum wage for hours worked.
What must be included. South Dakota law does not define "unpaid wages or compensation" in the final paycheck context, but the Department of Labor and Regulation's guidance states that the final paycheck must include "all wages and compensation earned." This encompasses regular wages for the final pay period, plus commissions and overtime for hours already worked. South Dakota has no statutory requirement for employers to pay out accrued but unused vacation or paid time off at termination; inclusion of accrued PTO in the final paycheck is a matter of employer policy or individual employment contract. Employers who promise PTO payout in a written policy or agreement are typically bound by that commitment, but the baseline statutory rule does not mandate it.
No acceleration for involuntary discharge. Unlike jurisdictions that require immediate or same-day payment upon involuntary termination, South Dakota applies the same "next regular payday" standard to all separations. An employer that pays biweekly on Fridays may terminate an employee on a Monday and lawfully defer the final paycheck until the following Friday (the next regular payday), provided the employee has returned all employer property.
