Form CT-1120A-CU Instructions Purpose Use Form CT-1120A-CU to calculate each taxable member’s apportionment fraction for the net income and minimum tax bases. Complete and attach Form CT-1120A-CU 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. Apportionment Calculation Net Income Apportionment If any member of the combined group carries on or does business outside of Connecticut or if any member is a financial services company, as defined in Conn. Gen. Stat. § 12-218b, the group is entitled to apportion its net income. If the group is entitled to apportion, each taxable member separately calculates its apportionment fraction in order to determine its portion of the combined group’s net income. Prior to calculating each taxable member’s net income apportionment fraction, the nontaxable member’s Connecticut receipts are assigned to taxable members. These receipts are assigned to taxable members on a pro rata basis in accordance with the ratio of each taxable member’s Connecticut receipts over the total of all taxable member’s Connecticut receipts. Once the nontaxable member’s Connecticut receipts are assigned to taxable members, each taxable member must calculate its apportionment fraction. In general, each taxable member must utilize a single receipts factor to apportion the combined group’s net income. To calculate its net income apportionment fraction, each taxable member includes its individual Connecticut receipts (including receipts assigned to it from nontaxable members) in the numerator and the combined group’s everywhere receipts in the denominator. For net income apportionment purposes, receipts from transactions among members of the combined group are eliminated. In addition, receipts related to items of income not included in a combined group’s unitary business or prohibited from Connecticut taxation under the United States Constitution or other federal law are excluded from the net income apportionment calculation. Each taxable member’s apportionment fraction is multiplied, individually, by the combined group’s net income. Form CT-1120A-CU Instructions (Rev. 12/23) Receipts Subject to Special Apportionment Rules Net income derived from the following activities must be separately apportioned from all other net income: • Carrying of passengers or property for hire – Form CT-1120A-BMC; • Services to regulated investment companies – Form CT-1120A-IRIC; • Securities brokerage services – Form CT-1120A-SBC; • Broadcasting and programming production services – Form CT-1120A-BPE; and • Credit card activities by financial service companies – Form CT-1120A-CCA. Net income that is subject to these special apportionment rules should be removed from the combined group’s net income (on Form CT-1120CU-NI, Part III, Line 2) and separately apportioned according to the applicable provisions. Similarly, receipts from the activities whose net income is subject to special apportionment should be excluded from the standard apportionment calculation. Manufacturers and financial service companies should include their income and receipts in the calculation of the group’s net income and standard apportionment calculation, respectively. Manufacturers should use the standard sourcing rules explained in the instructions to Schedule Q. Financial service companies should use the rules provided under Conn. Gen. Stat. § 12-218b to source their receipts. See the instructions to Form CT-1120A-FS for more information on financial service company sourcing rules. Minimum Tax Base Apportionment If any member of the combined group carries on or does business outside of Connecticut, the group is entitled to apportion its minimum tax base. Similar to the method used to apportion the combined group’s net income, taxable members separately apportion the combined group’s minimum tax base. Each taxable member’s minimum tax base apportionment fraction includes its assets sourced to Connecticut under Conn. Gen. Stat. § 12-219a in the numerator and the everywhere assets of the entire combined group in the denominator. For minimum tax base apportionment purposes, the average monthly net book value of a part year member’s assets should be prorated to reflect the percentage of the group’s income year it was included in the group. In each member column, for both taxable and nontaxable members, enter the Member Number from Form CT-1120CU-MI, Combined Group Member Information, and the name of the corporation being reported.

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.
