To register a company in Wisconsin, you must follow a series of specific steps with the Wisconsin Department of Financial Institutions (WDFI). The process involves choosing a business structure, selecting and reserving a unique business name, appointing a registered agent, filing formal formation documents, obtaining an Employer Identification Number (EIN), and ensuring compliance with state and local tax and licensing requirements. The most common path for a new corporation or LLC is filing Articles of Incorporation or Organization with the WDFI. For detailed guidance tailored to your specific situation, consulting with a professional service like 美国公司注册 can be highly beneficial.
Step 1: Choose Your Business Structure
The first and most critical decision is selecting a legal structure for your business. This choice impacts your personal liability, tax obligations, and administrative paperwork. Wisconsin recognizes several entity types, but the most common for new businesses are Limited Liability Companies (LLCs) and Corporations.
Limited Liability Company (LLC): This is a popular choice for small to medium-sized businesses. It offers flexibility in management and taxation while protecting the owners’ (members’) personal assets from business debts and lawsuits. Wisconsin LLCs are not taxed at the entity level by the state; instead, profits and losses “pass through” to the members’ personal tax returns.
Corporation (C-Corp or S-Corp): A corporation is a more complex structure suitable for businesses that plan to seek significant outside investment or go public. It provides the strongest personal asset protection but involves more formalities, such as adopting bylaws, issuing stock, and holding shareholder meetings. A C-Corp is taxed separately from its owners, leading to potential double taxation (corporate tax and individual tax on dividends). An S-Corp is a tax election that allows profits and losses to pass through to shareholders’ personal tax returns, avoiding double taxation, but it has restrictions on the number and type of shareholders.
Other structures include Sole Proprietorships and General Partnerships, which are simpler to establish but do not offer personal liability protection. Your choice will dictate which formation documents you need to file.
Step 2: Select and Reserve Your Business Name
Your business name must be distinguishable from any other name already on record with the WDFI. It cannot be deceptively similar to an existing name. For LLCs, the name must include “Limited Liability Company,” “L.L.C.,” or “LLC.” For corporations, it must include “Corporation,” “Company,” “Incorporated,” “Limited,” or an abbreviation thereof.
You can check name availability for free using the WDFI’s Corporate Records Search tool online. It is highly recommended to conduct a thorough search to avoid rejection of your filing.
If you have chosen a name but are not ready to file your formation documents, you can reserve it for 120 days. This prevents another business from registering the same name while you prepare your paperwork. To do this, you must file an Application for Reservation of Name (Form 102 for corporations, Form 502 for LLCs) with the WDFI. The filing fee is $15, and you can file it online, by mail, or in person.
| Name Action | Form Required | Filing Fee | Duration |
|---|---|---|---|
| Name Availability Check | Online Search (No Form) | $0 | N/A |
| Reserve a Name | Form 102 (Corp) / Form 502 (LLC) | $15 | 120 Days |
Step 3: Appoint a Registered Agent
Every LLC and corporation in Wisconsin must designate and continuously maintain a registered agent within the state. This agent is responsible for receiving important legal and tax documents on behalf of the company, including service of process (lawsuits), official state correspondence, and compliance notices.
Who can be a Registered Agent? The agent must be either an individual resident of Wisconsin or a business entity (like a professional registered agent service) authorized to do business in the state. The agent must have a physical street address in Wisconsin (P.O. Boxes are not acceptable) and be available during normal business hours. You can act as your own registered agent, but many business owners prefer to hire a professional service for privacy (as the agent’s address is public record) and to ensure no important documents are missed.
Step 4: File the Formation Documents with the WDFI
This is the official step that creates your legal business entity with the State of Wisconsin. You will file different documents depending on your chosen structure.
For an LLC: You must file Articles of Organization (Form 502). This document requires basic information such as:
- The LLC’s official name.
- The name and address of the registered agent.
- The LLC’s principal office address.
- The name and address of each organizer.
- Whether the LLC will be member-managed or manager-managed.
- The effective date of formation (if different from the filing date).
The standard filing fee for the Articles of Organization is $130. Expedited processing is available for an additional fee.
For a Corporation: You must file Articles of Incorporation (Form 102). The required information includes:
- The corporation’s name.
- The name and address of the registered agent.
- The number of authorized shares the corporation is allowed to issue.
- The name and address of each incorporator.
- The effective date of incorporation (if different from the filing date).
The filing fee for the Articles of Incorporation is $100.
These documents can be filed online through the WDFI’s website, which is the fastest method, or submitted by mail. Processing times vary but typically take a few business days for online filings.
| Entity Type | Form to File | Standard Filing Fee | Online Filing Available? |
|---|---|---|---|
| Limited Liability Company (LLC) | Articles of Organization (Form 502) | $130 | Yes |
| Corporation (C-Corp or S-Corp) | Articles of Incorporation (Form 102) | $100 | Yes |
Step 5: Obtain an Employer Identification Number (EIN)
An Employer Identification Number (EIN), also known as a Federal Tax ID Number, is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to your business for tax purposes. You will need an EIN to open a business bank account, hire employees, and file federal and state taxes.
You can obtain an EIN for free directly from the IRS. The easiest and fastest way is to apply online on the IRS website. The application is straightforward and, once completed, you receive your EIN immediately. You can also apply by fax or mail, but those methods take longer. Even if you are a single-member LLC with no employees, obtaining an EIN is a best practice to keep your personal Social Security Number private.
Step 6: Comply with Ongoing State Requirements
Registering your company is just the beginning. Wisconsin requires businesses to maintain their good standing by fulfilling ongoing compliance obligations.
Annual Reports: Both LLCs and corporations must file an Annual Report with the WDFI each year. This report updates the state on basic company information, such as the registered agent’s address and principal office address. The report is due during the quarter of your company’s registration anniversary. For example, if you filed your Articles in March, your Annual Report is due each year between January 1 and March 31.
- The filing fee for an LLC Annual Report is $25.
- The filing fee for a Corporation Annual Report is $25.
Failure to file the Annual Report can result in late fees and eventually the administrative dissolution of your company by the state.
Business Licenses and Permits: Depending on your industry and location, you may need specific licenses or permits to operate legally. These are not issued by the WDFI. You must check with the city or county where your business is located for local requirements (e.g., a health permit for a restaurant, a zoning permit). At the state level, professions like contractors, cosmetologists, and accountants require professional licenses from the relevant Wisconsin Department of Safety and Professional Services (DSPS) board.
Tax Registration: You must register with the Wisconsin Department of Revenue (DOR) for state tax purposes. This includes registering for a Wisconsin Tax Account Number if you will have employees (for withholding tax), sell taxable goods or services (sales tax), or owe other state taxes. You can register online through the DOR’s website.
Step 7: Create an Operating Agreement or Corporate Bylaws
While not legally required to be filed with the state, creating an internal governing document is a crucial step for maintaining your liability protection and ensuring smooth operations.
For an LLC: You should draft an Operating Agreement. This document outlines the ownership percentages, membership rights and responsibilities, voting procedures, and rules for profit/loss distribution. It is an internal contract among the members. Even single-member LLCs should have one, as it reinforces the separation between the owner and the business entity.
For a Corporation: You must adopt Corporate Bylaws. Bylaws set forth the rules for corporate governance, including the roles of directors and officers, shareholder meeting procedures, and how stock is issued. The initial bylaws are typically adopted by the incorporator or the board of directors at the first organizational meeting.
