AICPA Representative Tasks (verbatim). 1. Remembering & Understanding, Recall the requirements for filing a consolidated federal Form 1120, U.S. Corporation Income Tax Return. 2. Application, Calculate taxable income for a consolidated federal Form 1120, U.S. Corporation Income Tax Return, including elimination of intercompany transactions.
Before any consolidated return analysis, determine whether corporations qualify as an affiliated group under IRC §1504. Two ownership thresholds must be satisfied:
\text{Affiliation Test} = \text{80% Vote} \cap \text{80% Value}
The common parent must directly own stock meeting both thresholds in at least one includible corporation. Subsequent tiers require that one or more group members collectively own 80% vote and value.
KEY: Both prongs must be satisfied simultaneously. Owning 90% of vote but only 70% of value fails the test. Preferred stock with limited voting rights counts toward value but not vote.
Not all corporations qualify for consolidation. IRC §1504(b) excludes:
TRAP: A domestic subsidiary owned 100% by a foreign parent cannot file a consolidated return with the foreign parent. The foreign corporation is not an includible corporation.
Common mistakes
- Treating consolidation as mandatory once ownership reaches 80%. Consolidated returns are always elective. The election is made by filing; no separate Form 1120 election statement is required. Trap: "80% ownership requires consolidation." Correct: 80% ownership permits consolidation; the group chooses whether to elect.
- Recognizing intercompany gain before external sale. Gain on sales between consolidated group members is deferred, not eliminated. Trap: "intercompany sales are tax-free." Correct: gain is deferred until the buying member sells to a non-member or leaves the group.
- Confusing elimination with deferral. Intercompany dividends are eliminated permanently. Intercompany gains are deferred temporarily. Trap: "both dividends and gains are deferred." Correct: dividends disappear; gains resurface upon triggering event.
Bottom line
- An affiliated group requires a common parent owning at least 80% vote AND value of at least one includible corporation, with 80% chain ownership continuing down
- Consolidated returns are elective but binding once filed; all members must continue unless the IRS grants permission to deconsolidate
- Intercompany transactions are eliminated or deferred until a triggering event with an outside party (dividends eliminated permanently, gains deferred)
- SRLY rules limit a joining member's pre-consolidation NOLs to income that member generates within the consolidated group
Exam shortcut
80-80 Rule: Affiliation requires 80% vote AND 80% value. If either is below 80%, no consolidation. Check both metrics on every ownership fact pattern. DEED for Intercompany: Dividends Eliminated, Everything else Deferred. Intercompany dividends vanish from consolidated income; intercompany gains wait for external sale. SRLY = Same-entity Rule: Pre-acquisition NOLs stay "locked" to the member that generated them.
