What payroll deductions are employers required to withhold?

Payroll Tax Withholding Requirements for Employers in South Dakota

In South Dakota, employers must comply with federal and state payroll tax withholding rules to ensure proper payroll management and regulatory compliance.

Mandatory Payroll Deductions

• Federal Income Tax Withholding: Employers are required to withhold federal income taxes based on employee W-4 forms and IRS tax tables.
• Social Security and Medicare Taxes (FICA): Employers must withhold 6.2% for Social Security and 1.45% for Medicare from employee wages. Employers also contribute matching amounts.
• Federal Unemployment Tax (FUTA): While not withheld from employee wages, employers must pay FUTA taxes separately.
• South Dakota State Income Tax: South Dakota does not impose a state income tax, so no state income tax withholding is required.
• Other Voluntary Deductions: Employers may withhold voluntary deductions such as retirement plan contributions, health insurance premiums, or wage garnishments as authorized by employees or court orders.

Operational Considerations

• Accurate Recordkeeping: Maintain precise payroll records including withheld amounts and employee authorizations.
• Timely Deposits: Deposit withheld federal taxes according to IRS schedules to avoid penalties.
• Payroll Automation: Utilize payroll software to automate tax calculations and withholdings for accuracy and efficiency.
