Payroll in a Tight Labour Market
Watertown employers compete hard for welders, assemblers, technicians and nurses, and that shows in their payroll: shift premiums, attendance and referral bonuses, relocation help and overtime. South Dakota has no state income tax withholding, but federal withholding, Social Security and Medicare, federal unemployment tax, South Dakota reemployment assistance, new-hire reporting and year-end forms are all required. BOMCAS runs payroll for Watertown employers remotely.
Employer registration and statewide payroll reporting are on our South Dakota payroll page. Here we look at shift pay, recruiting payments, students and Minnesota work for Watertown employers.

Shifts, Bonuses and Overtime
Production employers often pay second- and third-shift differentials and production or attendance bonuses. Under federal wage law, most of these must be included in the regular rate when calculating overtime, so overtime pay is higher than time and a half of base pay alone. Payroll systems also need to separate the premium portion of overtime because employees can deduct qualified overtime pay on their federal returns for 2025 through 2028, and employers must report the amount. Bonuses are supplemental wages, which can be withheld at the flat federal rate of 22 percent.
Relocation and Recruiting Payments
Watertown employers, sometimes with help from local workforce programs, pay relocation costs or signing bonuses to attract workers. For most employees, moving expense reimbursements are taxable wages under current federal law, and signing bonuses are wages. Housing assistance and student loan repayment benefits each have their own rules. We set these up correctly in payroll so W-2s are accurate.
Students and Interns
Lake Area Tech students often work part time or in internships while they study. Their wages are subject to normal payroll taxes, and interns are generally employees unless the internship meets the federal test for unpaid training. High school students in dual credit or work-based learning programs may also be employed, and child labour rules on hours and hazardous work apply to employees under 18.
Seasonal Lake Businesses
Resorts, marinas and restaurants on the lakes hire extra staff in summer. They need new-hire reporting, tip reporting and tip credits for food and beverage businesses, and they must file quarterly returns even in quarters without wages if they have not closed their accounts. Employees who receive free lodging should have its treatment reviewed.
Minnesota Employees and Work
When a Watertown employer sends workers to install, repair or build in Minnesota, the wages earned there are taxable in Minnesota and the employer is generally required to withhold Minnesota tax after registering. Minnesota residents who work only in Watertown owe Minnesota tax on their wages, but the employer is not required to withhold it; it may agree to withhold voluntarily if registered. Minnesota's paid leave and sick and safe time laws apply to employees who work enough in Minnesota, so employers with significant Minnesota work should check whether they must report and pay premiums.
Staffing Agencies and Temporary Workers
Several Watertown plants fill production lines partly through staffing agencies, and smaller firms sometimes do the same in busy seasons. When an agency is the employer of record, it handles payroll taxes and W-2s, but the client should still confirm the agency is current on its deposits and workers' compensation. Temporary workers hired directly need the same onboarding as other employees: Form W-4, Form I-9, new-hire reporting and correct classification as employees rather than contractors. Converting a temporary worker to a permanent hire mid-year needs care so wage bases for unemployment taxes are counted correctly.
Workers' Compensation
South Dakota employers generally buy workers' compensation from private insurers. The policy's payroll classification and payroll totals should agree with payroll records, because premium audits compare them. Crews working in Minnesota or other states may need coverage endorsements for those states.
Setting Up
We need your EIN, South Dakota reemployment assistance account, employee details, pay rates, benefits and year-to-date totals if you are switching mid-year.
Watertown Payroll Questions
Do Watertown employers withhold state income tax?

Usually yes. Most shift differentials and nondiscretionary bonuses are included in the regular rate used to calculate overtime.
Are relocation payments taxable?
For most employees, yes. Moving expense reimbursements are generally taxable wages under current federal law.

Possibly. Review your workers' compensation policy and Minnesota payroll obligations before crews start work there.

Payroll has to tie to the books and support wages on the business return. Owner salary is a planning choice, missed quarters go through catch-up filing, employees may need personal return help, businesses selling services must keep sales tax current, and Canadian hires raise cross-border questions.
