$20 an Hour After Taxes in South Dakota (2026)

How Your SD Paycheck Works

South Dakota paychecks start with federal income tax withholding under IRS Publication 15-T using the employee's Form W-4, pay period, and taxable wages. FICA applies: Social Security is 6.2% on wages up to the $184,500 wage base in 2026, and Medicare is 1.45% on all covered wages. Employers must withhold the 0.9% Additional Medicare Tax once wages paid to an employee exceed $200,000 in the calendar year. South Dakota does not impose a state individual income tax; the South Dakota Department of Revenue confirms there is no state income tax on wages. South Dakota also has no statewide employee payroll deduction for disability insurance or paid family leave that reduces standard take-home pay. For standard paycheck calculations, only federal income tax and FICA affect South Dakota employees. Estimates assume standard 2026 withholding, single filing status, and no pre-tax deductions; actual paycheck may differ.
