Payroll in Madison
Madison employers range from technology firms hiring remote developers in other states to lake restaurants that double their staff each summer. South Dakota has no state income tax withholding, so in-state payroll centres on federal withholding, Social Security and Medicare, unemployment insurance and new-hire reports. Remote employees elsewhere bring other states' rules. BOMCAS runs payroll for Madison employers remotely.
Statewide registration and reports are on our South Dakota payroll page; here we cover remote staff in other states, student workers, summer crews and farms.
Remote Employees in Other States
A Madison technology company that hires a developer living in Minnesota, Colorado or elsewhere must generally register as an employer in that state, withhold its income tax and pay its unemployment insurance. Some cities and counties also have local payroll taxes. We register the company where needed and run withholding for each state.
Student Workers
DSU students often work part-time for local businesses. They complete Forms W-4 and I-9, and those expecting no federal tax may claim exemption from withholding each year. Students working for a private employer are generally covered by unemployment insurance. International students on F-1 visas have work limits, and their wages are usually exempt from Social Security and Medicare while they are nonresidents.
Summer Lake Season
Resorts, marinas and restaurants hire seasonal staff, including high school and college students. Federal child labour rules limit hours for 14- and 15-year-olds and restrict hazardous work for those under 18, including operating some power equipment and, in many cases, driving. Final pay at the end of the season should be issued on the next regular payday.
Tipped Staff
Restaurants and bars must report tips each pay period and calculate overtime on the full minimum wage. The FICA tip credit and the federal tip deduction for employees for 2025 through 2028 make accurate reporting worthwhile for both sides.
Manufacturing and Suppliers
Suppliers to the Manitou plant and other manufacturers often pay shift differentials and production bonuses, which must be included in the regular rate for overtime. The qualified overtime premium should be tracked separately for employees' federal deduction.
Farm Employers
Farm payroll has its own federal rules. Agricultural employers file Form 943 instead of Form 941, and wages to farm workers are subject to Social Security and Medicare once thresholds are met. Federal unemployment applies to larger farm payrolls.
Stock and Equity Compensation
Start-ups paying employees partly in equity must report the value of non-qualified options when exercised and restricted stock when it vests as wages, with withholding. We coordinate with the company's equity records.
What We Handle
- Pay runs and direct deposit.
- Federal deposits and Forms 941, 943 and 940.
- Out-of-state registration and withholding.
- State reemployment assistance and new-hire reports.
- W-2s and 1099s.
Year-End
We reconcile quarterly returns to annual totals, prepare W-2s with overtime and tip reporting, and file W-2s and 1099s by January 31, sending forms to seasonal staff and students at their current addresses.
Benefits
Health insurance, retirement plans, HSAs and education assistance plans reduce taxable wages when set up correctly. Small employers starting a retirement plan may qualify for start-up credits.
Workers' Compensation and Insurance
Insurers audit payroll by job class. Separating office, shop, field and seasonal wages, and matching them to quarterly returns, keeps the audit short and premiums accurate. For remote employees in other states, coverage must meet each state's requirements.
Paying Owners
S corporation owners must take a reasonable salary through payroll before distributions. We help set the salary level based on the work performed.
New employers also need workers' compensation coverage and a state unemployment account before the first payday; we help with both.
Each quarter we send a short summary of headcount and labour costs by department.
Madison Payroll Questions
We hired a remote developer in another state. What do we need?
Usually registration as an employer in that state, its income tax withholding and unemployment insurance.
Do farm employers file Form 941?
No. Agricultural employers file Form 943 for farm workers.
Can DSU students claim exemption from withholding?
Yes, if they expect to owe no federal tax. It must be renewed each year.
How is equity compensation reported?
Exercised options and vested stock are wages subject to withholding.
