Payroll in a Three-State Labour Market
Sioux Falls employers hire from a labour market that crosses state lines. The Census Bureau's Sioux Falls metropolitan area includes Rock County, Minnesota, because of commuting, and many workers also come from northwest Iowa. South Dakota itself does not tax wages, so a Sioux Falls payroll has no state income tax withholding. That changes when employees live or work in Minnesota or Iowa, which do tax wages. BOMCAS runs payroll for Sioux Falls employers, handling the federal and South Dakota filings and the out-of-state questions that come with local hiring.
State unemployment insurance and new-hire reporting work the same in every South Dakota town, as our South Dakota payroll page sets out, so this page is about the Sioux Falls labour market.
South Dakota Basics for Sioux Falls Employers
- Reemployment assistance tax: paid by the employer on the first $15,000 of each employee's wages in 2026. First-year rates are 1.75 percent in total for most new employers and 6.55 percent for construction firms, a gap that adds up quickly for the many contractors building in Sioux Falls.
- Quarterly wage reports: due April 30, July 31, October 31 and January 31.
- New-hire reporting: every new or rehired employee is reported to the South Dakota New Hire Reporting Center within 20 days of their first day of paid work.
- Minimum wage:$11.85 an hour in 2026, or a $5.925 cash wage for tipped staff whose tips make up the difference, rising to $12.30 and $6.15 on January 1, 2027.
Employees Who Live in Minnesota
Minnesota taxes its residents on all their income, wherever they earn it. A South Dakota employer is not required to withhold Minnesota income tax for a Minnesota resident working in Sioux Falls. The employee can ask for voluntary Minnesota withholding, and the employer may agree or decline. If nothing is withheld and the employee expects to owe $500 or more, they generally need to make Minnesota estimated payments. Employers that agree to withhold register with the Minnesota Department of Revenue and file there. We help employers decide on a policy, explain it to staff, and set up the Minnesota account when needed.
The answer changes if the employee actually works in Minnesota, for example on jobs in Luverne or from a home office across the line. Minnesota generally expects withholding on wages for work performed in the state, and the employer may owe Minnesota unemployment insurance for that employee instead of South Dakota reemployment assistance tax.
Employees Who Live in Iowa
Iowa also taxes residents on all their income, at a flat 3.8 percent for 2026. Whether a Sioux Falls employer must withhold Iowa tax depends on whether it has an office or does business in Iowa. Otherwise, the employee may request voluntary withholding or make estimated payments. Employees working on Iowa job sites or from Iowa homes raise the same work-location questions as in Minnesota. We review each Iowa-resident employee's situation and set up withholding accordingly.
Hospitals, Clinics and Shift Work
Health care is the largest employer group in Sioux Falls. Clinics, home health agencies, senior care providers and staffing firms that compete for the same workers as Sanford Health and Avera Health run complex payrolls: shift differentials, on-call and call-back pay, overtime under the federal rules, and benefits deductions. Federal law now gives workers a deduction for the premium part of qualified overtime from 2025 through 2028, and employers must report qualified overtime on information returns. We set up pay codes that keep the overtime premium separate from regular pay so it can be reported correctly.
Restaurants, Bars and Hotels
Tipped workers in Sioux Falls's restaurant and hotel trade need tip reporting that meets both the state cash-wage rule and the federal rules. With the new federal deduction for qualified tips, employers must report certain cash tips and the worker's occupation on information returns. We track tips each pay period and check that every tipped employee reaches the minimum wage.
Plants, Warehouses and Seasonal Peaks
Food processing, distribution and e-commerce warehouses employ large hourly workforces with overtime and frequent hiring. Every new hire, including rehires and short-term staff hired for peak seasons, needs a new-hire report within 20 days and correct federal withholding from their Form W-4.
Federal Payroll Duties
- Federal income tax withholding, Social Security at 6.2 percent each on wages up to $184,500 in 2026, and Medicare at 1.45 percent each, plus 0.9 percent additional Medicare withholding above $200,000.
- FUTA at 6.0 percent on the first $7,000 of wages, less a credit of up to 5.4 percent for state unemployment tax paid.
- Deposits, quarterly Form 941, annual Form 940, and Forms W-2 by January 31.
What You Receive
Each pay period we calculate pay, withholding and employer taxes, process direct deposit, make tax deposits and update a payroll register that ties to the books. Each quarter we file the South Dakota wage report and federal returns, and any Minnesota or Iowa filings. In January we issue W-2s that match the four quarterly filings.
Sioux Falls Payroll Questions
Do I have to withhold Minnesota tax for an employee who lives in Minnesota but works in Sioux Falls?
No. A South Dakota employer is not required to withhold Minnesota income tax for a Minnesota resident working in South Dakota. The employee can ask for voluntary withholding, and the employer may agree or decline.
What if my Sioux Falls employee works some days in Minnesota or Iowa?
Wages for work performed in another state can bring withholding and unemployment insurance duties there. We review where each employee actually works and set up the right state accounts.
What is the reemployment assistance rate for a new Sioux Falls construction company?
A first-year construction employer pays 6.55 percent in total, including the investment fee, on up to $15,000 of wages per worker in 2026. Most other new employers pay 1.75 percent.
When must I report a new hire?
Within 20 days of the employee's first day of paid work, to the South Dakota New Hire Reporting Center. This includes rehires and short-term and seasonal staff.
Talk to BOMCAS About Payroll in Sioux Falls
Payroll posts straight to the ledger, so most Sioux Falls payroll clients also use our bookkeeping, and the year's wage totals flow into the business return. Owners deciding between salary and distributions should look at tax planning. Employers with missed quarterly filings can start with back taxes and late filing, employees who live in Minnesota or Iowa can have their personal returns prepared here, and hospitals and clinics hiring Canadian staff should read cross-border tax. Employers that sell taxable services also need their sales tax current. The statewide rules behind the rest of our work are explained on our South Dakota pages for business tax preparation, personal tax preparation, sales and use tax, bookkeeping, tax planning, back taxes and late filing and cross-border tax, and the South Dakota overview brings them together.
