For corporations, Wisconsin has a couple of filings that resemble franchise taxes, either in name or format, that are typically filed by an accountant: an annual report filing and a franchise tax filing.
Foreign-registered corporations in Wisconsin must report on "Capital representation" in Wisconsin on the state's annual report (Form Corp18), which is used to calculate the filing fee. It requires detailed financial information; as a result, this is typically filed by an accountant.
Foreign corporations must file their annual report by March 31 each year.
The first annual report is due during the first calendar quarter following the entity's initial registration in Wisconsin.
For example, if the entity registered in Wisconsin on February 1, the first annual report would be due March 31 of the following year, and then annually by March 31 thereafter.
Failure to file the annual report can result in administrative dissolution or revocation of authority to do business in Wisconsin.
Wisconsin also has franchise taxes that must be filed each year for certain entities. Wisconsin’s franchise tax more closely resembles corporate income taxes than the average franchise tax filing in other states. The state has a concise Q&A on corporate taxes on its website.
