Wisconsin LLC Costs: What You Actually Pay

Only a couple of costs are genuinely mandatory to form and maintain a Wisconsin LLC. Everything else is optional, and knowing the difference keeps you from overpaying.

The formation filing fee

To create your LLC you file the Articles of Organization (DFI Form 502) with the Wisconsin Department of Financial Institutions, and the state charges a filing fee for it. Wisconsin prices this differently depending on how you file: $130 online, or $170 on paper. The gap is deliberate. The paper surcharge took effect March 1, 2024, nudging filers toward the faster online system, which you reach from the DFI's File Online page.

The annual report fee

Once formed, every Wisconsin LLC files an annual report with the DFI, starting the year after formation. The fee is $25 online, or $40 on paper. It is a modest recurring cost, and it is not a tax on your income. It simply keeps your registered agent, registered office, principal office and at least one member or manager current on the state's record.

That is the required list

For a Wisconsin LLC, those two are the core mandatory state costs: the one-time formation fee and the recurring annual report fee. Wisconsin does not charge an LLC franchise tax, which keeps the ongoing burden lighter than in some states. Everything below is optional and depends on your situation.

Beyond the required fees, several common add-ons are worth understanding so you can decide which ones you actually need.

Registered agent service

You can be your own registered agent for free if you're a Wisconsin resident with a business office at a Wisconsin street address and an email address, which Wisconsin's statute requires of every agent. If you would rather keep your home address off the public record, or you are out of state and need a Wisconsin address, a commercial registered agent service handles that for an annual fee. For out-of-state owners this is effectively required, since the registered office must be a physical Wisconsin address. Changing agents later costs $10 online or $25 on paper.

Name reservation

If you have a name but are not ready to file, reserving it with the DFI for 120 days costs $15. Most owners skip this and simply file once they are ready, but it is useful if you need to lock a name while you finish other steps.

Expedited processing

The DFI says most online filings are accepted on receipt, but if you are on a hard deadline (or filing on paper) the state offers expedited service for $100, acted on by the close of the next business day, or four-hour counter service for $250. Given how fast standard online processing usually is, most filers do not need it.

Certified copies and certificate of status

When a bank, lender, or another state asks for proof, you may want a certified copy of your filed Articles or a certificate of status (good standing) from the DFI. Each carries a small fee and is ordered only when someone specifically requires it.

Assumed name registration

If you plan to operate under a name other than your legal LLC name, registering that assumed name with the DFI costs a small fee. Only relevant if you are branding under a different name.

Some expenses have nothing to do with LLC formation itself but come with running a real business in Wisconsin.

Seller's permit and sales tax

If you sell taxable goods or services in Wisconsin, you register with the Wisconsin Department of Revenue for a seller's permit. Registration itself is inexpensive, but it comes with the ongoing responsibility to collect and remit sales tax. This is separate from anything the DFI charges.

Professional and occupational licenses

Wisconsin issues no single general business license, but many trades and professions require their own state licensing, each with its own fee and renewal cycle. A contractor, a cosmetologist, and a real estate broker all face different licensing costs. Check whether your field requires a state license before you assume formation is the last fee.

Local permits

Cities and counties sometimes require local business permits or zoning approvals, particularly for storefronts, food service, or home-based businesses with customer traffic. These are set locally and vary widely.

EIN

An Employer Identification Number from the IRS is free. Apply directly at IRS.gov and never pay a third party who only charges to obtain the number itself. If you form with Mainstay Filing, we apply for it for you as part of the yearly fee.

Understanding which costs are state fees, which are optional services, and which are ongoing lets you build an accurate budget rather than reacting to surprises.

Formation year vs. later years

Your first year carries the one-time formation fee ($130 online) and any optional services you choose at startup, such as registered agent service, expedited processing, or certified copies. There's no annual report in year one: the DFI says the first report is due starting the year after your LLC is formed. From year two on, the recurring state cost is the $25 online annual report, plus whatever it costs to keep an agent in place if you arrange that on your own. (Form through Mainstay Filing and there is no separate agent renewal to track, because the agent and the annual report filing ride along inside the same flat yearly service fee.) Because Wisconsin has no franchise tax, the steady-state cost of keeping an LLC alive is genuinely modest.

How to avoid overpaying

• File online. It's $40 cheaper than paper ($130 versus $170) and faster. There is rarely a reason to file on paper.
• Get your EIN yourself. It is free from the IRS; do not pay anyone a fee whose only value is obtaining the number.
• Skip services you do not need. Expedited processing and name reservation are useful in specific situations, not by default.
• Weigh registered agent service honestly. If you have a stable Wisconsin address you are comfortable making public, being your own agent is free. If you value privacy or are out of state, the annual fee buys real convenience and compliance.

What Mainstay Filing charges for

When you form through us, a single flat yearly fee covers everything we do: preparing and filing your Articles correctly, serving as your registered agent all year, every year, and preparing and filing your annual report when it comes due. There is no separate agent charge and no separate annual-report charge; a renewal year is simply the same fee again. The state's filing fee and its annual report fee are pass-through costs, with no markup on the government fees, and the receipt card beside this page shows what checkout charges.
