(November 2024)

In This Article

Starting a sole proprietorship in Wisconsin is a straightforward process that allows you to quickly launch your own business without the complexities of forming a corporation or partnership. As a sole proprietor, you have full control over your business operations, but it’s important to understand the specific steps you need to operate legally in Wisconsin.

This guide walks you through everything from registering your business name to understanding tax obligations, ensuring you’re well-prepared to start your entrepreneurial journey with confidence.

1. Know What a Sole Proprietorship Means and How it Works

To begin a sole proprietorship in Wisconsin, know what it is and how it works. A sole proprietorship is the simplest and most common form of business ownership, where you, as the sole owner, have full control over every aspect of the business. In this structure, there’s no legal distinction between you and the business, meaning all profits, liabilities, and debts are directly yours.

While this gives you complete decision-making power, it also means you’re personally responsible for any losses or legal issues. Starting a sole proprietorship involves minimal paperwork and lower costs, making it an attractive option if you’re looking to quickly start and run a business on your own terms.

2. Choose a Business Name

To start a sole proprietorship in Wisconsin, choose a business name. Your business name has to reflect the nature of your services or products while being unique enough to stand out in the market. Remember, in Wisconsin, if you’re operating under your own name, you may not need to register a business name, but if you opt for a different name, you need to take the next step.

3. Register the Business Name with the Wisconsin Department of Financial Institutions

To commence a sole proprietorship in Wisconsin, register the business name with the Wisconsin Department of Financial Institutions. If you choose a business name that isn’t your own legal name, you need to register it with the Wisconsin Department of Financial Institutions. This process ensures that the name you choose is legally recognized and protected within the state. Registering your business name also prevents others from using it, helping you establish a distinct brand identity.

4. Obtain Necessary Licenses and Permits

To launch your sole proprietorship in Wisconsin, obtain necessary licenses and permits. Depending on your business type and location, you may need specific licenses or permits to operate legally in Wisconsin. These can range from general business licenses to industry-specific permits. Check with your local city or county government to determine what licenses and permits are necessary for your particular business.

5. Apply for an Employer Identification Number (EIN) from the IRS

To run a sole proprietorship in Wisconsin, apply for an Employee Identification Number (EIN) from the IRS. Even if you don’t have employees, obtaining an Employer Identification Number (EIN) from the IRS is often necessary for opening a business bank account and filing taxes. The EIN acts as a social security number for your business and is important for keeping your personal and business finances separate.

6. Register for Wisconsin State Taxes

To commence a sole proprietorship in Wisconsin, register for the state taxes. As a sole proprietor in Wisconsin, you need to register for state taxes, including sales tax if you’re selling products. This registration process ensures you’re compliant with state regulations and can operate without legal complications. You can register for Wisconsin state taxes online through the Department of Revenue.

7. Open a Business Bank Account

To register a sole proprietorship in Wisconsin, open a business bank account. Separating your personal and business finances is critical for managing your sole proprietorship effectively. Opening a business bank account helps you keep track of your business expenses, simplifies tax filing, and presents a more professional image to your clients and vendors.

8. Set Up Accounting and Bookkeeping Systems

To begin a sole proprietorship in Wisconsin, set up accounting and bookkeeping systems. Remember that accurate financial records are vital for the success of your sole proprietorship. Also, setting up reliable accounting and bookkeeping systems help you manage your cash flow, prepare for tax season, and understand the financial health of your business.  To simplify the process,  opt for accounting software.

9. Comply with Local Zoning Laws

To begin a sole proprietorship in Wisconsin, comply with local zoning laws. Before starting your business at all, ensure that your business location complies with local zoning laws. This is very important because zoning laws regulate where certain types of businesses can operate and restrict business activities in residential areas. Check with your local zoning  office to confirm that your business is compliant.

10. Obtain Business Insurance (If Necessary)

To kickstart a sole proprietorship in Wisconsin, obtain business insurance—if it’s necessary for your business. Depending on your industry, you may need general liability insurance, professional liability insurance, or other types of coverage. Business insurance helps safeguard your personal assets and ensures your business can withstand unforeseen challenges.

Recap

To start a sole proprietorship in Wisconsin, first, understand that this business structure means you’re the sole owner with full control and personal responsibility for all liabilities. Begin by choosing a business name that reflects your brand, then register it with the Wisconsin Department of Financial Institutions if it’s different from your legal name.

Secure any necessary licenses and permits to operate legally. Apply for an EIN from the IRS and register for Wisconsin state taxes. Open a business bank account to separate finances, and set up accounting systems. Ensure compliance with local zoning laws, and consider obtaining business insurance to protect your assets.
