Form 1CNP is a Wisconsin Corporate Income Tax form. Many states have separate versions of their tax returns for nonresidents or part-year residents - that is, people who earn taxable income in that state live in a different state, or who live in the state for only a portion of the year. These nonresident returns allow taxpayers to specify which which income is subject to the state's taxes, and which is not.

About the Corporate Income Tax

The IRS and most states require corporations to file an income tax return, with the exact filing requirements depending on the type of company.

Sole proprietorships or disregarded entities like LLCs are filed on Schedule C (or the state equivalent) of the owner's personal income tax return, flow-through entities like S Corporations or Partnerships are generally required to file an informational return equivilent to the IRS Form 1120S or Form 1065, and full corporations must file the equivalent of federal Form 1120 (and, unlike flow-through corporations, are often subject to a corporate tax liability).

Additional forms are available for a wide variety of specific entities and transactions including fiduciaries, nonprofits, and companies involved in other specific types of business.

Historical Past-Year Versions of Wisconsin Form 1CNP

We have a total of eleven past-year versions of Form 1CNP in the TaxFormFinder archives, including for the previous tax year. Download past year versions of this tax form as PDFs here:
