How to choose payroll companies in Wisconsin

Where to find payroll companies in Wisconsin's cities and regions

Payroll here means answering to two state agencies. The Department of Revenue handles income tax withholding, and the Department of Workforce Development (DWD) runs unemployment insurance and its quarterly wage reports. There is no city or county income tax to add on top, so a Wisconsin employer's payroll is simpler than in states with local wage taxes. The state side still has to be done correctly every pay period.

Most providers sit in the southeast. Milwaukee is the largest city in the state, and its metro reaches into Waukesha County, where Waukesha, Brookfield, Menomonee Falls and Delafield all have firms of their own. South and north of the city you will also find options in Franklin and Grafton. This is where you get the widest choice, including firms that focus on manufacturers, restaurants, or union shops.

Madison, the capital and second largest city, has a smaller group of providers serving Dane County employers. Along the lake, Racine and Kenosha businesses often compare local firms with Milwaukee ones. In the northeast, Green Bay and the Fox Cities around Appleton, Neenah and Oshkosh make up the next biggest market.

Elsewhere, providers tend to be regional accounting firms or independent bureaus that cover several counties. That holds in Eau Claire and La Crosse in the west, Wausau up north, Janesville, Milton and Evansville in Rock County, and lakeshore towns like Sheboygan, Manitowoc and Kiel. Fond du Lac and Delavan fit the same pattern. Smaller markets can mean fewer specialists, but you will often deal with the owner. Remote service from a bigger city is also a reasonable fallback.

Wisconsin payroll rules a provider has to handle for you

Ask any provider exactly which of these tasks they take on, and get it written into the agreement.

• Withholding. You need a Wisconsin withholding tax number from the Department of Revenue, separate from your federal EIN. The department assigns a deposit schedule (annual, quarterly, monthly or semi-monthly) and you file an annual reconciliation. Confirm the provider makes those deposits on your assigned schedule.
• Unemployment insurance. You register with DWD for a UI account, then file quarterly contribution and wage reports. Tax applies to the first $14,000 of each employee's wages in a calendar year, and new employers start at a set rate based on payroll size. Check that your rate notice is loaded correctly each year.
• New hire reporting. Report new hires within 20 days, plus rehires who come back after a gap of 60 days or more. Form WT-4 or a W-4 with birth and hire dates works. Many providers do this automatically; some leave it to you.

Pay frequency matters when you set up the schedule. State law requires paying employees at least monthly, covering wages earned up to no more than 31 days before payday, with quarterly pay allowed for logging and farm labor. A final paycheck, whether the person quit or was fired, is due by the next regular payday or the monthly deadline, whichever comes first. If you close, merge, sell or relocate the business, unpaid wages are due within 24 hours. Ask how fast the provider can cut an off-cycle check.

If you are considering a professional employer organization (PEO) rather than a plain payroll service, the firm must be registered with the Department of Financial Institutions, and those registrations expire every July 31. Ask for proof of current registration. Figures here change, so confirm current rates and thresholds with the agency before you rely on them.

How to compare payroll companies in Wisconsin

Start with how you want help. A local bureau in Appleton or Waukesha may visit to set you up and will know Wisconsin's forms and notices from years of filing them. A national platform usually costs less per check for simple payrolls but routes problems through a call center. Neither is wrong. Match it to how often your payroll changes.

On quotes, look past the per-run price. Ask what year-end W-2s, extra runs, garnishments, new state registrations and termination of the contract each cost. Check who pays penalties if a deposit is late because of the provider's error, and whether that promise is in the contract or only in a sales sheet.

Questions worth asking before you sign:

• Will one named person handle my account, and who covers when they are out?
• Do you carry errors and omissions insurance and a fidelity or crime bond?
• How do you handle employees who live in Minnesota, Illinois, Iowa or Michigan?
• How much notice do I need to give to leave, and do I get my payroll history in a usable format?

The border question deserves a straight answer. Employers near the borders, from La Crosse to Kenosha, often have staff commuting from another state, and a provider that handles those workers routinely saves you headaches.

Finally, call two references with a business like yours, ideally in the same industry and part of the state. Ask how the provider handled a mistake, not just whether checks went out on time.
