Form CT-1120 is a Connecticut Corporate Income Tax form. Like the Federal Form 1040, states each provide a core tax return form on which most high-level income and tax calculations are performed. While some taxpayers with simple returns can complete their entire tax return on this single form, in most cases various other additional schedules and forms must be completed, depending on the taxpayer's individual situation, to create a complete income tax return package.

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.
