34.3 Consolidated Returns and Affiliated Corporations

Why consolidated returns are advanced TCP material

A consolidated return lets an affiliated group file one federal Form 1120. TCP tests it because it stacks entity classification, ownership analysis, source-data review, intercompany eliminations, and loss utilization. You must fix group membership before any arithmetic, because an incorrect group produces an incorrect return no matter how clean the later math is.

Affiliated-group screen (Section 1504)

The statutory test is a chain of includible corporations connected through a common parent that owns stock with at least 80% of total voting power and at least 80% of total value of at least one other member, with that 80%/80% chain continuing through the group. Apply two filters in order:

Note the contrast with the CFC and dividends-received-deduction worlds: consolidation demands 80% of BOTH vote and value. An 80%-voting-but-70%-value subsidiary is affiliated for some purposes but is not consolidatable.

Separate company first, consolidated second

Build two layers. First, compute each member's separate taxable income or loss from its own revenue, deductions, depreciation, gains, and losses. Second, layer in consolidated adjustments. This order prevents the classic simulation error of eliminating an item before you know which member booked it.

Example: Parent sells inventory to Sub at a $40,000 profit and Sub still holds it at year end. On separate books Parent shows the $40,000 gain and Sub holds inventory with that profit in basis. On the consolidated return the group has not sold to an outside customer, so the intercompany profit is deferred and is triggered only when Sub sells the goods outside the group (the matching rule).

Intercompany transactions

Intercompany items are not just inventory. Expect services, interest, royalties, rent, dividends, management fees, loans, and asset transfers. Ask whether the group earned income from an outside party or merely shifted dollars between members. Two high-frequency results: qualifying intercompany dividends are 100% eliminated (no DRD math needed inside the group), and intercompany gains and losses are deferred and matched to the buyer's later outside disposition. If the problem gives book income plus tax adjustments, reconcile to source data instead of assuming the trial balance already removed every intragroup entry.

Losses, limitations, and planning

Consolidation lets one member's income absorb another's loss, but not without limits. Capital losses still need capital gains. A loss a member brought into the group is a separate return limitation year (SRLY) loss usable only against that member's own consolidated contribution. An ownership change can trigger a Section 382 limitation that caps annual use of pre-change NOLs. Federal NOLs generated in 2018 and later carry forward indefinitely but offset only 80% of taxable income in a year. Do not invent limitation figures; if a limit depends on dates, ownership shifts, or asset values, the simulation supplies them.

Exam workflow

1. Draw the ownership chain and mark includible versus excluded corporations.
2. Confirm the 80% vote-and-value test and that the election or filing requirement is in the facts.
3. Compute each member's separate taxable income or loss.
4. Identify intercompany sales, dividends, interest, services, rents, royalties, and loans.
5. Eliminate intercompany dividends and defer intercompany gains under the matching rule.
6. Apply SRLY, Section 382, capital-loss, or 80% NOL limits stated in the scenario.
7. Present consolidated taxable income and note any planning effect.

The strongest answers prove group membership, preserve source data, then make the adjustments to report the affiliated group as one federal taxpayer; they never treat consolidation as a simple sum of book incomes.

Advantages and costs the exam expects you to weigh

A TCP planning question often asks whether to elect consolidation at all. The election is not free, and the candidate is expected to weigh both sides.

Investment-basis and excess-loss-account mechanics

Within a consolidated group, the parent's basis in a subsidiary's stock is adjusted annually for the subsidiary's income, losses, and distributions, much like an S corporation or partnership owner basis. If a subsidiary's losses exceed the parent's stock basis, the negative amount becomes an excess loss account (ELA), which is recaptured as income when the subsidiary stock is sold or the subsidiary leaves the group. TCP rarely asks for an ELA computation, but it may test the concept: a subsidiary cannot pass through unlimited losses to the parent forever without a basis consequence on disposition.

Worked consolidation example

Parent has $500,000 separate taxable income. Sub1 has a $120,000 loss. Sub2 has $80,000 income that includes a $30,000 dividend paid to Parent (intercompany) and $25,000 of deferred gain on equipment still held by Parent. Start separately: $500,000, ($120,000), and $80,000. Eliminate the $30,000 intercompany dividend (it appears in both Sub2 income and Parent income) and defer the $25,000 intercompany gain. The consolidated taxable income is roughly $500,000 - $120,000 + $80,000 - $30,000 - $25,000 = $405,000, before any SRLY check on Sub1's loss.

Naming the eliminations explicitly, rather than summing $500,000 - $120,000 + $80,000, is the exam point.

Common TCP traps

• Counting an 80%-vote-only subsidiary. Consolidation requires 80% of value too; a high-vote, low-value stake fails.
• Applying the dividends-received deduction inside the group. Intercompany dividends are eliminated entirely, so there is no 50%/65%/100% DRD computation among members.
• Forgetting SRLY and Section 382 together. An acquired loss corporation can hit both a SRLY ceiling and a Section 382 annual limit; the more restrictive controls.
