Form 1100X is a Delaware Corporate Income Tax form. An amended tax return is used to correct errors or omissions in a previously-filed tax return. While taxpayers will not generally be punished simply for correcting an error in a previous return, errors that resulted in an underpayment of owed tax can sometimes result in penalties or interest owed.
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.
