Wisconsin has a strong base of manufacturers, farms, trades and tourism businesses, and a straightforward LLC process run by the Department of Financial Institutions (DFI). It costs $130 to form an LLC online and $25 a year to keep it in good standing. The details to get right are the annual report’s quarterly deadline and the licensing rules for trades.
What a Wisconsin LLC costs
Table of Contents
| Item | Cost | When |
|---|---|---|
| Articles of Organization | $130 online; $170 by mail | At formation |
| Annual report | $25 online (more on paper) | By the end of the calendar quarter of your anniversary |
| Seller’s permit (if selling taxable goods or services) | Small state fee | Before your first taxable sale |
| Trade name registration (optional) | Small state fee | If you choose to register |
Step 1: Choose your LLC name
The name must include "limited liability company", "limited liability co.", "LLC" or "L.L.C." and be distinguishable from other names on file with DFI. Search DFI’s corporate records, then check federal trademarks, domains and social handles with our business name checklist.
Wisconsin doesn’t require a statewide filing to use a trade name, but you can register a trade name with DFI for added protection.
Step 2: Appoint a registered agent
Every Wisconsin LLC needs a registered agent with a physical Wisconsin address, available during business hours. You can serve yourself, name another adult or use a commercial agent.
Step 3: File Articles of Organization with DFI
File Articles of Organization online with DFI for $130, or by mail for $170. You’ll include the LLC’s name, registered agent and office, whether it’s managed by members or managers, and the organizer’s name and signature. Online filings are typically approved quickly, and expedited service is available.
Step 4: Create an operating agreement
Wisconsin doesn’t require you to file an operating agreement, but every LLC should have one, setting out ownership, management, profit sharing and what happens when members join or leave.
Step 5: Get an EIN and open a bank account
Apply for a free EIN from the IRS online, then open a business bank account using your filed Articles and EIN. See choosing a business bank account.
Step 6: Register for state taxes
Register with the Wisconsin Department of Revenue online for:
- A seller’s permit, if you sell taxable goods or services. Wisconsin’s state sales tax is 5%, and most counties add a local tax.
- Employer withholding, if you hire.
Employers also register with the Department of Workforce Development for unemployment insurance.
Step 7: Get licenses and credentials
- Dwelling contractors. Anyone who obtains building permits for one- and two-family homes must hold a dwelling contractor credential from the state’s safety and professional services department, with a qualified individual who completes required training.
- Electricians and plumbers need state credentials.
- Many professions are licensed by state boards.
- Local permits and licenses cover zoning, signs and certain business activities.
Step 8: File your annual report on time
Wisconsin’s annual report deadline works differently from most states. It’s due by the end of the calendar quarter in which your LLC’s anniversary falls, starting the year after formation. For example, an LLC formed in May (second quarter) files by June 30 each year.
Filing online costs $25. DFI sends a reminder, but you’re responsible for filing even if it doesn’t arrive. LLCs that don’t file can be administratively dissolved.
How a Wisconsin LLC is taxed
By default, LLC profits pass through to the owners, who pay federal income tax, self-employment tax and Wisconsin’s graduated personal income tax. Multi-member LLCs taxed as partnerships file a Wisconsin partnership return. Wisconsin also lets eligible pass-through entities elect to pay tax at the entity level. LLCs electing C corporation status pay Wisconsin’s franchise or income tax for corporations. Ask a tax professional which option suits you.
Hiring your first employee in Wisconsin
Beyond the federal steps in our first employee guide, Wisconsin employers generally:
- Register for withholding with the Department of Revenue and unemployment insurance with the Department of Workforce Development.
- Carry workers’ compensation insurance once they have three or more employees, or sooner if they pay $500 or more in wages in a calendar quarter.
- Report new hires to the state.
- Follow Wisconsin’s wage payment rules.

Wisconsin rules for common types of business
Food businesses. Restaurants, food trucks and many retail food businesses are licensed by the state agriculture department or local health departments acting as its agents. Wisconsin allows some home-baked goods and other low-risk foods to be sold directly to consumers without a license, within limits. See our cottage food business guide.
Childcare. Child care centers and family child care homes are licensed by the state’s children and families department. See our home daycare guide.
Tourism and lodging. Short-term rentals and lodging businesses in Wisconsin generally need state or local licenses and collect room taxes; check with your municipality.
Starting a farm, food or agritourism business in Wisconsin
Wisconsin’s rural economy supports many small LLCs built around farms, food and visitors: market gardens, orchards, maple syrup, cheese and dairy products, farm stays and pick-your-own operations. A few points apply to many of them:
- Food processing and sales often need licenses from the state agriculture department, especially for dairy, meat and packaged foods.
- Agricultural tourism may involve local zoning approvals, signage rules and liability considerations; many owners carry specific insurance.
- Farm property and equipment can have different tax treatment from other businesses, so involve an accountant familiar with agriculture.
An LLC is a common structure for these businesses because it separates farm and personal liabilities. See our ideas for a market garden and other farm businesses in the idea finder.
Understanding the quarterly deadline
Because the deadline is tied to a quarter rather than a fixed date, it’s worth writing yours down now:
| If your LLC was formed in… | Your annual report is due by… |
|---|---|
| January, February or March | March 31 |
| April, May or June | June 30 |
| July, August or September | September 30 |
| October, November or December | December 31 |
DFI’s records show your due date, and the reminder notice confirms it.

Mistakes to avoid
- Misreading the annual report deadline. It’s the end of your anniversary quarter, not your anniversary date.
- Pulling building permits without a dwelling contractor credential.
- Selling taxable goods without a seller’s permit.
- Letting your registered agent lapse.
- Mixing personal and business finances.
- Ignoring the reminder notice because it arrives in a different month from your formation date.
