When you decide to form a new LLC in Wisconsin, there are certain things to be aware of to ensure you are meeting the requirements that are put in place by the state. Wisconsin allows both single-member LLCs (owned by one person or entity) and multi-member LLCs (owned by multiple people or entities), each with distinct tax and compliance considerations. You can follow a simple check list that will cover the important aspects to focus on. These steps will include:

  1. Choose a business name - Your business name will be required to be unique and distinguishable from other active businesses in the state, and will need to include a designator in the name such as "LLC" or "Limited Liability Company".

  2. Appoint a registered agent - All LLCs that are formed in Wisconsin will need to have an active registered agent who will be responsible for receiving any service of process and important notices sent to your business by the secretary of state.

  3. Submit your articles of organization - This will be the document that officially forms your LLC with the state and will include your business information, registered agent information, and ownership information.

  4. Draft an operating agreement - This document will outline the roles and responsibilities for the owners of the business, as well as the processes for decision making and ownership percentages.

  5. Obtain an EIN - An EIN will be issued to your business by the IRS and will be needed for filing taxes, hiring employees, and opening a business bank account.

  6. Open a business bank account - A dedicated business bank account will make sure you are not mixing personal and business finances and strengthen your liability protection as an owner of an LLC in Wisconsin.

  7. Maintain good standing with the state of Wisconsin - After you have formed your LLC you will need to keep it in good standing by submitting annual reports, keeping your business information updated, and registering for any business licenses that are required by your industry.

This process applies to all business entities seeking to form an LLC, and it is essential to follow Wisconsin LLC naming rules and comply with Wisconsin law to ensure your application is approved.

This guide will cover these steps in detail and provide tips on how to best complete them. When you form a new LLC, you can choose to either do this process on your own or you can hire a service such as Firstep, to handle all these steps for you. Professional help can ensure all formation paperwork is filed correctly. LLCs are one of the most popular business types due to their ease of starting, flexibility in making changes, and providing personal liability protection to the owners of the business.

Step 1: Choosing a Business Name

Before you are able to submit your articles of organization, you will need to choose a name for your LLC. The name will have to be unique and distinguishable enough from any other active business names that are currently registered with the state and include a designator such as “LLC”, “Limited liability company”, or “L.C.C.”. Wisconsin LLC naming rules require that your LLC name be distinguishable from the names of other business entities already registered with the Department of Financial Institutions, and simply changing a letter or adding punctuation does not make a name unique under Wisconsin law. For a business name to be considered taken, the business will need to be active and in good standing with the state. If a business has been administratively dissolved or has fallen out of good standing then that name will be considered available, as Wisconsin does not hold names for any reason.

To know what names are available to choose, you can use Wisconsin’s business search bar to go through potential names you are considering and see if they are currently in use or not. The name must be distinguishable from other business entities, including LLCs, corporations, and other legal structures. Even if the exact name is not being used, it’s important to be aware that your LLC name will need to be distinguishable enough from other business names. Changing one letter or small changes like that will not make a name unique enough to be approved. Avoid using terms in your name that do not correlate to your business such as professional services like “bank”, “law”, or “insurance”. Businesses in professional industries will typically need approval and licenses prior to formation and being misleading in your name can lead to issues down the road.

If you want to reserve an LLC name before filing, you can submit a Name Reservation Application to the Department of Financial Institutions. This will reserve your chosen name for up to 120 days for a $15 fee.

Step 2: Appoint a Registered Agent

A registered agent is a required aspect that any LLC in Wisconsin will need to ensure they are meeting. Whoever you appoint as your business’s registered agent whether that be yourself, a trusted friend or family member who is a Wisconsin resident, or a registered agent service like Firstep, they must have a physical address in the state. The registered agent must also be available during normal business hours, Monday-Friday 9am-5pm, to accept service of process and other legal documents on behalf of the LLC.

This is so important because every Wisconsin LLC must designate a registered agent who is responsible for receiving legal documents, tax notices, and official correspondence sent to your business. Getting these documents in a timely manner helps to avoid any default judgements imposed on your business by courts, as these judgements are typically harsh on your business.

If you choose to act as your own registered agent, be aware that your address will become public information as this will be listed on your business page by the state. If you would like to avoid this, then hiring registered agent services or having someone else act as your registered agent will be your best choice.

Step 3: Submit Your Articles of Organization

With your name chosen and your registered agent set, you are now ready to submit your formation paperwork called the Articles of Organization, which is the essential legal document required to officially form your new LLC in Wisconsin. Filing articles can be done either by mail or you can file online through the business formation form on Wisconsin’s state website. Online filings are highly convenient and typically approved immediately, while mailed filings are processed within 5 business days. The online filing fee is $130, whereas mail submissions cost $170.

You will need to provide the name of your LLC, your registered agent information, your office address, and the organizers or members of the business. You will then be asked to sign the document to certify it, add your contact information, and submit the payment for the form.

Your Articles of Organization will be the founding documents of your LLC, so it’s important to ensure all the information you input is correct and updated. Check the spelling of your name, addresses, and registered agent information to avoid having to pay extra fees to fix this after approval.

Step 4: Draft an Operating Agreement

Now that your articles of organization have been filed and your business formation is approved, it can be very helpful to draft an operating agreement for your LLC. This document will outline the LLC structure, including the roles and responsibilities of owners, voting rights, decision making processes, and how to settle disputes within the business. The operating agreement can also specify whether the LLC will be managed by its members or by one or more managers, which is especially important for a multi member LLC. An operating agreement is not required by the state of Wisconsin, but it can be very useful in defining these roles for your members.

As your business grows and starts to scale, having these responsibilities in writing is helpful to avoid internal disputes within your business and to ensure members understand how your processes and decision making is done. These documents also detail the process for members joining and leaving the business, and ensure these are done in a standardized fashion. Your operating agreement might be required by banks to open a business bank account, and these also help strengthen your liability protection by detailing how your business is keeping the separation between personal and business assets.

Step 5: Obtain an EIN (Employer Identification Number) For Your Business

An Employer Identification Number (EIN) is a nine-digit number assigned by the Internal Revenue Service (IRS) to identify a business for tax purposes, much like a Social Security Number for individuals. While single-member LLCs are not required to obtain an EIN unless they have employees or elect to be taxed as a corporation, it is highly recommended for opening a business bank account, hiring employees, and working with vendors. Firstep is able to obtain this EIN for you during the formation process, or you can get this yourself directly through the IRS.

For single-member LLCs, the IRS generally treats them as disregarded entities for federal tax purposes, meaning the LLC’s profits and losses are reported on the owner’s personal tax returns rather than on a separate business return. If you lose your EIN documentation, you cannot apply for a new number, but you can retrieve your existing EIN through the IRS, though this process can be time-consuming. So, keep your EIN information accessible for tax filings and business transactions.

Step 6: Open a Business Bank Account

Once you have officially formed your LLC in Wisconsin and obtained the required documents, a highly suggested next step will be to set up a dedicated business bank account. This account will be used to separate your personal and business finances, which will strengthen your liability protection that is granted to you as an owner of an LLC. The liability protection will act as a shield for your personal assets as long as your business is operating legally and you continue to keep your finances separated. This is important in case any debts or lawsuits are imposed on your business then they will not be able to go after your personal assets and only your business assets.

The shield that protects your assets is commonly referred to as the corporate veil and this will stay active as long as you maintain the guidelines mentioned above. If the corporate veil is pierced, then your liability protection will be lost and your personal finances and assets will be at risk. Other than this important aspect, business bank accounts will allow you to easily track your business cash flow as it will all be going through one dedicated account.

The protection of your personal assets, the easy tracking of business funds, and added credibility for your business are just a few advantages of opening a business bank account. As your business grows, this will be even more important since you will need to track larger amounts of money and maintain accurate records and estimates for your finances.

Step 7: Maintaining Ongoing Compliance For Your LLC

After formation and obtaining the necessary documents involving that, the most important aspect of keeping your business in good standing is ensuring the ongoing compliance for your LLC. This will include things such as submitting annual reports accurately and on time, as well as registering and renewing any required business licenses that are needed by businesses in your specific industry. It is crucial to meet all reporting requirements, including filing annual reports with the Wisconsin Department of Financial Institutions. Business tax registration is necessary for state and local tax compliance, and you must register for applicable taxes such as sales tax and employment taxes. Depending on your business location and activities, you may also need to obtain local licenses or permits by checking with city or county offices. When submitting ownership information and tax registration forms, your mailing address is required for proper documentation and correspondence.

Annual Reports

With your business officially formed, you will need to ensure you are submitting annual reports each year accurately and on time. In the state of Wisconsin, there are 4 set windows businesses will need to renew their business in and it corresponds to the date you formed your LLC. These renewal windows are January 1st-March 31st, April 1st-June 30th, July 1st-September 30th, and October 1st-December 31st. Whatever window your formation date falls into will be your window to file, and you are able to file your annual report any day within this window. Annual reports in Wisconsin will cost $26 with all fees included and the approval process will be instant. Your certified document will be sent to your contact email on file after submission.

Business Licenses

Depending on your business type or the industry you are in, you may need to also apply for and renew business licenses to ensure you are meeting all requirements by the state. Typically, the businesses that will be required to do this are professional services such as healthcare, law, insurance, banks, or construction. These will usually be filed locally but depending on your industry this could change. Be sure to double check that you are meeting all requirements that are put in place by state guidelines for your business to maintain your good standing and continue operating legally.
