What it means
The starting point is that companies are separate taxpayers, so a group with one profitable arm and one loss making arm would normally pay tax on the profits and simply carry the losses forward. Consolidation removes that mismatch by taxing the group on its combined result.
The election is not a formality. Once a group files on a consolidated basis it is generally expected to keep doing so, and joining or leaving the group mid year brings complicated rules about which slice of income belongs where.
Eliminations are the second big effect. If the manufacturing subsidiary sells goods to the distribution subsidiary at a profit, that profit is not real from the group's point of view until an outside customer buys the goods, so it is deferred rather than taxed straight away.
Consolidation applies to income tax and does not automatically extend elsewhere. State taxes, payroll taxes and sales taxes usually still follow each legal entity, and several states apply their own rules on which members must be combined.
The trade off is administrative. A consolidated return requires each subsidiary's figures to be prepared, intercompany transactions tracked all year and a single set of attributes such as losses and credits tracked at group level, which is real work for a modest group.
In practice
Real-world examples.
Example
A retail group opens an online arm that loses $6,000,000 in its first two years while the shops earn $20,000,000. Consolidating lets the group use those losses immediately, cutting the cash tax bill in the same years the investment is made.
Example
A manufacturer sells components to its own assembly subsidiary at a mark up. On a consolidated return the mark up on stock still sitting in the assembly warehouse at year end is deferred, so the group is taxed only on goods that have actually left it.
Example
A private equity backed group buys a competitor and holds it through a new subsidiary at 90% ownership. Because the holding exceeds the 80% test, the acquired company can be brought into the consolidated return from the day of the purchase.
Formula
Calculation
Consolidated taxable income = sum of each member's taxable income - intercompany eliminations
Group tax = consolidated taxable income x tax rate
A parent company earns taxable income of $4,000,000. Subsidiary A earns $1,500,000 and Subsidiary B, a young venture, loses $2,500,000. Filing separately at a 21% rate, the parent pays $4,000,000 x 21% = $840,000 and Subsidiary A pays $1,500,000 x 21% = $315,000, a group total of $1,155,000, while Subsidiary B pays nothing and carries its loss forward.
Filing on a consolidated basis, the group combines all three results: $4,000,000 + $1,500,000 - $2,500,000 = $3,000,000 of consolidated taxable income, giving tax of $3,000,000 x 21% = $630,000. The saving of $1,155,000 - $630,000 = $525,000 is simply the loss used now rather than years later, and it matches $2,500,000 x 21% = $525,000.
Now add an elimination. The parent sold goods to Subsidiary A for $500,000 at a profit of $200,000, and Subsidiary A still holds that stock at the year end, so the profit is deferred. Consolidated taxable income falls to $3,000,000 - $200,000 = $2,800,000, and the group's bill becomes $2,800,000 x 21% = $588,000.Case study
Seen in the real world.
This is an illustrative and entirely fictional example. Ferndale Holdings, an invented industrial group, ran a distribution business earning $6,000,000 a year and a manufacturing subsidiary losing $4,000,000 while it commissioned a new plant. The group owned 75% of the manufacturer, having left a quarter with the founding family at the time of the acquisition.
That 75% holding sat below the 80% threshold, so no consolidated return was possible. Ferndale paid $6,000,000 x 21% = $1,260,000 of tax on the distribution profits while the manufacturing losses sat unused on the other company's books.
The group bought out the minority shareholders and consolidated from the following year. Combined taxable income became $6,000,000 - $4,000,000 = $2,000,000, tax fell to $2,000,000 x 21% = $420,000, and the fictional group saved $1,260,000 - $420,000 = $840,000 of cash tax in a single year.
Watch out
Common mistakes.
- Assuming any group of commonly owned companies can consolidate, when the ownership threshold and the affiliated group definition rule out many structures.
- Forgetting that intercompany profit sitting in unsold stock must be eliminated, which overstates group taxable income and the tax paid on it.
- Expecting the consolidated election to cover state and local taxes as well, when those often follow separate and inconsistent rules.
Questions
People also ask.
Is filing a consolidated return the same as consolidated financial statements?
No, the accounting consolidation follows control under accounting standards, while the tax consolidation follows a stricter ownership test, so the two groups frequently differ.
Can a group leave the consolidated group later?
A member that falls below the ownership threshold leaves, but rejoining is normally restricted for a period of years, so the decision should not be treated as reversible.
Who is liable if the tax is not paid?
Members of a consolidated group are generally jointly and severally liable for the group's tax, meaning one company can be pursued for the whole amount.
