Form 6CS is a Wisconsin Corporate Income Tax form. States often have dozens of even hundreds of various tax credits, which, unlike deductions, provide a dollar-for-dollar reduction of tax liability. Some common tax credits apply to many taxpayers, while others only apply to extremely specific situations. In most cases, you will have to provide evidence to show that you are eligible for the tax credit, and calculate the amount of the credit to which you are entitled.

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.
