No matter where someone lives, starting up a business requires time and effort. In the state of Wisconsin, there are also specific rules and regulations that business owners have to follow. Like most states, Wisconsin makes it relatively easy to set up and operate an LLC, as long as owners follow the necessary and required guidelines and laws. Doing that can mean a successful start to an LLC and a better chance at a long-term future.

Getting Started

Naming the LLC

To name an LLC in the state of Wisconsin, specific language is required. The name must contain either L.L.C., LLC, or Limited Liability Company. It also has to avoid restricted words, although these can sometimes be included with the filing of additional paperwork. Prohibited words are any that are already being used by a federal or state agency, and those cannot be used in the name of an LLC at all. To see if a name is available or is already in use by another company, the owner of an LLC can search online and see what their options are.

Selecting a Registered/Statutory Agent

A registered or statutory agent is one that is allowed to accept official correspondence for the business, and only a resident of the state or a corporation authorized to do business in that state can qualify. That is done because someone must always be available to receive anything official, and someone living out of state will not have that same level of availability. A registered agent is generally not a legal requirement, but an LLC that does not name one can lose out on good standing with the state and may miss important documentation that can affect the business.

Filing Articles of Organization

The Articles of Organization for an LLC can be filed online or by a paper copy. The fee for filing online is $130, while the fee for filing on paper is $170. Both are acceptable means of filing, however, so an LLC can choose which option it prefers.

Creating an Operating Agreement

Wisconsin does not require an operating agreement for an LLC. Like most states, this regulation has either been done away with or has never been part of the path to operating an LLC in the state. While the LLC can certainly have an operating agreement if desired, proof of that agreement will not be needed by the state of Wisconsin.

Running Your Business

Getting Your EIN

What’s an EIN?

Setting Up for Taxes in Wisconsin

Unemployment insurance tax is required for businesses that have employees in the state of Wisconsin.

Income Tax

Wisconsin requires LLCs in the state to set up for employee withholding tax, to ensure the proper funds are being withheld from the employees’ checks and sent to the state.

Sales Tax

Any LLC that is selling goods or services that Wisconsin considers taxable must register for sales tax, too, and businesses should be mindful of any needed federal, state, or city permits.

Getting Insurance for your LLC

Workers’ compensation insurance is required for an LLC is Wisconsin. However, many companies choose to have insurance that goes above and beyond this, simply because it reduces their risk if there should ever be a problem with the company. Whether to purchase insurance over and above state requirements is a choice that will need to be made by each individual LLC.

Keeping Your LLC Compliant

To stay in compliance with Wisconsin law, an LLC must be sure that any employees hired are reported to the state as new hires, and that they are allowed to legally work in the US. Additionally, companies must provide workers’ compensation insurance, withhold income tax, print compliance posters, and provide increments to employees. But there is more to the issue of remaining in compliance with an LLC. An annual report must also be filed with the Secretary of State. This can be filed online, and the fee is $25. It is due every year on the last day of the quarter in which the LLC was formed. A Certificate of Good Standing is also available through filing online or requesting form SP-48 to fill out.
