Starting a service business in Wisconsin

Form your business in Wisconsin

In Wisconsin, LLCs are formed with the Department of Financial Institutions (DFI), not a Secretary of State. Articles of organization cost $130 filed online or $170 on paper, as listed on DFI's corporation fee page in October 2026. DFI offers next-day expedited processing for $100 and same-day counter service in Madison at higher prices.

Ongoing state filings

Every Wisconsin LLC files an annual report with DFI. The fee is $25 online or $40 on paper, as listed by DFI in October 2026. Filing online saves $15 each year.

Using a business name (DBA)

DFI offers optional registration of a trade name or mark under Wis. Stat. § 132.01 for $15, valid for 10 years and renewable within six months before it expires. DFI says trademark registration is not required, and that registering a trade name is not the same as registering an entity and does not reserve the name in the state's business records. Ask your city or county whether it has its own rules for trade names before you letter the truck.

Licensing for service trades

DSPS issues most construction and trade credentials in Wisconsin. The Dwelling Contractor (DC) credential is for the owner, partner or chief executive of a contracting business that obtains building permits for one- and two-family dwellings, and the business must hold, or employ someone who holds, a Dwelling Contractor Qualifier (DCQ) certification, which DSPS renews with 12 hours of approved continuing education. DSPS requires a Dwelling Contractor to carry either a surety bond of at least $25,000 or general liability insurance of at least $250,000 per occurrence. DSPS also credentials electrical contractors, master and journeyman electricians (including residential classes), master and journeyman plumbers (including restricted service and appliance classes), and HVAC contractors and qualifiers. Lawn care, cleaning and painting companies that never pull a building permit are not on the DSPS list, but municipalities license businesses and issue permits on their own terms, so check with each city or village you serve.

Workers' compensation

The Department of Workforce Development (DWD) lists three triggers. You must carry workers' compensation insurance if you employ three or more full or part-time employees (coverage must start the day you hire the third person), or if you employ one or more people and pay combined gross wages of $500 or more in any calendar quarter for work in Wisconsin. Farmers have a separate rule (six or more workers on the same day for 20 days in a year). The $500 trigger is the one that catches new service companies: a single seasonal helper on a lawn or snow route crosses it within weeks. Coverage is bought from private carriers licensed by the Office of the Commissioner of Insurance, and businesses that cannot find a carrier can use the Wisconsin Workers' Compensation Insurance Pool.

Sales tax on services

The Wisconsin Department of Revenue's Publication 210 says the sale of landscaping and lawn maintenance services, including any property transferred to the customer with them, is subject to sales and use tax unless an exemption applies, whether the work is residential or commercial. Its taxable examples include mowing, edging, fertilizing, weed spraying, laying sod and tree and shrub trimming. The same publication lists plowing or removing snow among services that are not landscaping services, so a lawn and snow company taxes its summer invoices and treats winter plowing differently. If you need a seller's permit, sole proprietors register directly with the Department of Revenue; LLCs can use the state's One Stop Business Registration.

Recording business calls in Wisconsin

Wisconsin follows one-party consent. Wis. Stat. § 968.31(2)(c) permits interception by someone who is on the call, or who has the advance consent of someone on it, except when the purpose is criminal, tortious or otherwise injurious. Recording calls with your own customers is permitted; for anyone calling from an all-party state, read our guide to recording business calls.

See our guide to recording business calls before you turn on call recording or an AI receptionist.

How the seasons shape the work

Wisconsin's year splits cleanly. Long, cold winters with lake-effect snow near Lake Michigan and Lake Superior make snow plowing, salting, ice dam and furnace work the winter backbone, while the lawn, landscaping, painting and power washing season runs roughly April through October. Up North cabin and lake-home owners hire out opening, closing, dock and cleaning work around Memorial Day and Labor Day, and spring thaw brings sump pump and wet basement calls in the south.

Split lawn and snow on your invoices

Because Publication 210 treats lawn maintenance as taxable and snow plowing as outside landscaping services, a company selling a year-round property package should price and invoice the two separately. A single bundled seasonal contract makes it harder to show which part was taxable. Set up separate service items in your CRM before your first winter.

Then set up the back end that gets you hired

The paperwork makes you legal. Customers still have to find you, reach you and pay you. Before your first job, set up a business phone number, email on your own domain, a Google Business Profile, a simple website, and a way to send quotes and take card payments. The launch checklist lays out the order.
