Starting a business in Wisconsin means more than picking a name and opening your doors. You’ll need to meet legal requirements at the state and local levels to operate legally and avoid fines.
If you’re starting a new business, it’s helpful to have an overview of what to do before you launch it.
Choose a legal structure
The first step is selecting your business type. Common structures include sole proprietorship, partnership, LLC, and corporation. Each one comes with different rules for taxes, liability, and registration. An LLC is popular for small businesses because it protects personal assets and requires less paperwork than a corporation.
Once you choose a structure, check if your business name is available using Wisconsin’s corporate records search.
Register your business with the state
Most businesses need to register with the Wisconsin Department of Financial Institutions (DFI). If you’re forming an LLC or corporation, you must file Articles of Organization or Incorporation online. Sole proprietors and partnerships may not need to file with DFI unless operating under a trade name.
You’ll also need to get a federal Employer Identification Number (EIN) from the IRS for tax purposes and hiring employees.
Obtain licenses, permits, and zoning approvals
Depending on your industry and location, your business might need local or state licenses. For example, restaurants require food service permits and health inspections. Contractors often need trade-specific licenses. Always check with your city or county clerk to find out what’s required in your area.
Make sure your business location complies with local zoning laws. Some areas limit where you can operate based on your type of business.
Stay compliant after opening
After launching, you’ll need to stay in good standing. File annual reports with the DFI if you have an LLC or corporation. Renew any licenses as required and keep business records organized.
Starting a business takes planning, paperwork, and attention to detail. By following each legal step, you’ll avoid common mistakes and set your business up for success. Once you’re compliant with state and local rules, you can focus on running and growing your business.
