This page covers the state filing and the charges that follow it. For the procedural side — name availability, registered agent, bylaws and the federal EIN — see the formation guide and how to get an EIN, both of which apply to corporations as well as LLCs.
What it costs to incorporate and stay filed
State filing charges only. Corporate income tax and franchise tax are excluded — both depend on income or net worth, so no flat figure would be true for every corporation.
| Charge | Amount | How often |
|---|---|---|
| Articles of Incorporation - Business Corporation (DFI Form 2), filed under ch. 180 Wis. Stats. with the Department of Financial Institutions | $100 | One time |
| Annual Report (filed online through the DFI; no separately numbered paper form) | $25 | Every year |
| First-year state filing charges | $125 | — |
| Five-year state filing charges | $225 | — |
Wisconsin is the 21st cheapest of 49 states on the incorporation filing fee alone. Nationally the fee runs from $35 in Montana to $300 in Texas, averaging $113.06. It is a one-off charge, so over five years it is usually outweighed by the recurring report fee and any annual franchise or minimum tax.
States that are cheaper to incorporate in
A cheaper filing fee elsewhere rarely saves money if you actually operate in Wisconsin. Every state sets its own threshold for what counts as transacting business, and where that threshold is met an out-of-state corporation is generally required to register as a foreign corporation — which would mean fees in both states rather than one. Whether it applies to you depends on facts this page cannot see, so check foreign qualification in Wisconsin before incorporating elsewhere to save on the filing fee.
Wisconsin corporation vs Wisconsin LLC
State filing charges only. Corporate income tax and franchise tax are excluded because both depend on income or net worth, so no flat figure exists for either entity.
| Corporation | LLC | |
|---|---|---|
| Formation filing fee | $100 | $130 |
| Report cadence | Every year | Every year |
| Report fee | $25 | $25 |
Worth noticing: a corporation is $30 cheaper to file here than an LLC. That is the exception nationally — corporations are the cheaper filing in only 15 of the 50 states, the two entities cost the same in 25, and the LLC is cheaper in 10.

State taxes a Wisconsin corporation pays
Corporate income tax
| Applies | Yes |
| Rate | 7.9% flat corporation franchise or income tax on Wisconsin net income |
Franchise or gross-receipts tax
Wisconsin's corporate tax is a franchise tax measured by net income at a flat 7.9% (a 7.9% income tax applies instead to corporations not subject to the franchise tax). It is NOT calculated on net worth and has no minimum or maximum dollar cap.
What these totals leave out: the filing-charge figures on this page are what you pay the business filing office. They exclude corporate income tax and any franchise or gross-receipts tax, because both depend on income, net worth or receipts. The section above sets out what Wisconsinlevies — or that it levies neither. Where a state's franchise tax carries a flat minimum, that minimum is an unavoidable annual cost these totals do not include, and over five years it can be the larger number.

Frequently Asked Questions
Where these numbers come from
This page covers the state filing required to incorporate in Wisconsin and the charges that follow it. Every figure was checked against Wisconsin's own published sources on July 29, 2026— the state business filing agency's fee schedule, the governing statute, and where a state tax applies, the state Department of Revenue. Commercial formation-service pages were used as leads only and are never cited. Anything the review could not confirm from an official source is left blank on this page rather than filled with an estimate.
Corporate income tax and franchise tax are quoted as the state publishes them, as rate schedules and thresholds, and are excluded from every dollar total here. They depend on income or net worth, so there is no flat figure that would be true for every corporation.
