Department of Revenue Services State of Connecticut Form CT-1120CU-NI Instructions Purpose Use Form CT-1120CU-NI to calculate the combined group’s tax on the net income base. Complete and attach Form CT-1120CU-NI to Form CT-1120CU. Combined groups are subject to tax on the greater of their net income base or their minimum tax base (sometimes referred to as the capital base). See Special Notice 2016(1), Combined Unitary Legislation. General Information - How to Calculate the Combined Group’s Net Income A combined group’s net income is the aggregate net income or loss of each taxable member and nontaxable member, derived from a unitary business, subject to the following: • Each member calculates its net income derived from a unitary business as if it were filing a Corporation Business Tax return on a stand alone basis, subject to certain modifications described herein. • Dividends paid from one member to another are eliminated from the income of the recipient. • The principles set forth in the federal consolidated return regulations promulgated under IRC § 1502 shall apply to the extent consistent with the Connecticut combined group membership and combined unitary reporting principles. Income deferred in accordance with such principles is restored to the seller’s income if the object of the transaction is resold to an entity not in the combined group or resold to or converted by a combined group member for use outside of the unitary business. The income is also restored to the seller’s income if the buyer and seller are no longer part of the same combined group. The restored income is included in the seller’s net income as if it were earned immediately prior to the event that caused its restoration. • The charitable contribution limitation is calculated on a combined group’s net income, prior to the charitable contribution deduction. To the extent that a member’s charitable contribution deduction is limited, it may be carried forward by the member and utilized in a future year. To the extent that the group’s charitable contribution deduction is limited, each member shall deduct an amount equal to its pro rata share of the group’s allowable deduction. Charitable contribution carryforwards are treated as if they were charitable contributions made in the subsequent year. These carryforwards may be used by the member in a combined unitary tax return or, if it no longer files in a combined unitary tax return in the future year, a separate return. • Gains and losses from the sale or exchange of capital assets, property described in IRC § 1231(a)(3), and property subject to an involuntary conversion are removed from the separate member’s net income and aggregated at the group level. The net gain or loss is apportioned to the taxable members in accordance with the net income apportionment provisions. Apportioned net losses are carried forward by each taxable member separately. • No deductions are allowed for expenses that are attributable to income of any member of the combined Form CT-1120CU-NI Instructions (Rev. 12/23) group, which income is prohibited from Connecticut taxation under the United States Constitution or other federal law. Part I – Computation of Adjusted Federal Taxable Income Complete a column for each taxable and nontaxable member. If there are more than six members in the combined group, attach copies of Page 2 as needed using the same format. Lines 1 through 28 For each member of the combined group, enter the appropriate amounts that were reported on its federal Form 1120 (or that would have been reported if it filed such a return). Use the Eliminations column to eliminate any transactions between members of the combined group. Use the Adjustments column to adjust any line to reflect the combined unitary basis of reporting. For information on adjustments that are required to be made for combined unitary purposes, see How to Calculate the Combined Group’s Net Income, on this page. Also see Special Notice 2016(1), Combined Unitary Legislation. Line 29 The group’s capital gain or loss is determined at the group level. Use Line 29 to remove any capital gains or losses prior to arriving at adjusted federal taxable income. Gains and losses from the sale or exchange of capital assets, property described in IRC § 1231(a)(3), and property subject to an involuntary conversion are aggregated at the group level. The aggregate net gain or loss is then apportioned by the taxable members in accordance with the net income apportionment provisions. Apportioned net losses are carried forward by each taxable member separately. See the instructions to Part III, Line 7.

Under the original law, companies that timely filed Form CT-DTLD could claim one-seventh of their Net Deferred Tax Liability Deduction annually for a seven year period starting with their 2018 income year.

How to Apply NOLs After apportionment, NOLs are deducted from each taxable member’s portion of the combined group’s net income in accordance with the following: • NOLs incurred by a taxable member in a year when it filed a separate Corporation Business Tax return may be used only to reduce its apportioned amount of the combined group’s net income. • NOLs incurred by a group that filed a Form CT-1120CR, Combined Corporation Business Tax Return, or a Form CT‑1120U, Unitary Corporation Business Tax Return, in an income year prior to 2016 may be used to reduce the apportioned amount of the combined group’s net income of any taxable member that was included in the Form CT‑1120CR or Form CT-1120U in the loss year. Only the combined NOLs from a Form CT-1120CR, and not separate company NOLs from such a return that were available for preference tax purposes under Conn. Gen. Stat. § 12-223f, may be utilized. • NOLs incurred by a taxable member in a year in which it filed a combined unitary tax return as required in the Unitary Legislation may be used by the taxable member and/or may be shared with other members that were included in the combined group in the year of the loss (regardless of whether the member was a taxable member or nontaxable member in the loss year). A taxable member may not claim an NOL deduction that exceeds 50% of its portion of the combined group’s net income. NOLs generated by a group that filed a Form CT-1120CR or Form CT-1120U may be used by any member of such prior year’s return if they all are members of the current year Form CT-1120CU. Otherwise, these NOLs should be divided among the former members of the Form CT‑1120CR or Form CT-1120U as described in Special Notice 2016(1), Combined Unitary Legislation. These divided NOLs may be shared between Form CT-1120CU members that filed together in the loss year. See Special Notice 2016(1), Combined Unitary Legislation.

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.
