Address If the post office does not deliver mail to the street address and the corporation has a P.O. box, show the box number instead. Form 1120X (Rev. 11-2016) If the corporation receives its mail in care of a third party (such as an accountant or an attorney), enter on the street address line “C/O” followed by the third party’s name and street address or P.O. box. Column (a) Enter the amounts from the corporation’s return as originally filed or as it was later amended. If the return was changed or audited by the IRS, enter the amounts as adjusted. Column (b) Enter the net increase or net decrease for each line being changed. Use parentheses around all amounts that are decreases. Explain the increase or decrease in Part II. Column (c) Note: Amounts entered on lines 1 through 4 in column (c) must equal the amounts that would be entered on the applicable lines of the tax return if all adjustments and corrections were taken into account. Lines 1 and 2. Add the increase in column (b) to the amount in column (a) or subtract the column (b) decrease from column (a). Enter the result in column (c). For an item that did not change, enter the amount from column (a) in column (c). Line 4. Figure the new amount of tax using the taxable income on line 3, column (c).

Enter the amount from the “Overpayment” line of the original return, even if the corporation chose to credit all or part of this amount to the next year’s estimated tax. This amount must be considered in preparing Form 1120X because any refund due from the original return will be refunded separately (or credited to estimated tax) from any additional refund claimed on Form 1120X. If the original return was changed by the IRS and the result was an additional overpayment of tax, also include that amount on line 8. Line 10. Tax due. If the corporation does not use electronic funds transfers, including the Electronic Federal Tax Payment System (EFTPS), enclose a check with this form and make it payable to the “United States Treasury.” Line 11. Overpayment. If the corporation is entitled to a refund larger than the amount claimed on the original return, line 11 will show only the additional amount of overpayment. This additional amount will be refunded separately from the amount claimed on the original return. The IRS will figure any interest due and include it in the refund. Line 12. Enter the amount, if any, to be applied to the estimated tax for the next tax period. Also, enter that tax period. No interest will be paid on this amount. The election to apply part or all of the overpayment to the next year’s estimated tax is irrevocable. Page 4 Who Must Sign The return must be signed and dated by: • The president, vice president, treasurer, assistant treasurer, chief accounting officer, or • Any other corporate officer (such as tax officer) authorized to sign. If a return is filed on behalf of a corporation by a receiver, trustee, or assignee, the fiduciary must sign the return, instead of the corporate officer. A return signed by a receiver or trustee in bankruptcy on behalf of a corporation must be filed with a copy of the order or instructions of the court authorizing signing of the return. If an employee of the corporation completes Form 1120X, the paid preparer’s space should remain blank. Anyone who prepares Form 1120X but does not charge the corporation should not complete that section.

Form 1120-X is a Federal 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.
