South Dakota tax guide
South Dakota maintains a competitive economic environment by forgoing a state personal income tax entirely. This policy, paired with a low regulatory burden, makes the state highly attractive for both workers and business owners looking to maximize their net earnings. Unlike many of its neighbors, such as Minnesota with its 9.85% top rate, South Dakota allows residents to keep every dollar of their gross income free from state-level income tax assessments.
Key tax highlights
Payroll
- Employees in South Dakota see zero state income tax withheld from their gross paychecks.
- Paycheck calculations focus exclusively on federal income tax withholding and mandatory FICA (Social Security and Medicare) taxes.
- Employers are not required to register for or withhold any state-level income tax, simplifying payroll administration for businesses operating within the state.
Local taxes
