Tax LawLegal glossary term
Quick answer
Controlled group usually means affiliated corporations treated as one taxpayer. In contracts, it matters because tax benefits and liabilities flow across members. Before signing, check ownership percentages and any parent‑subsidiary clauses.
Definitions
What is controlled group?
Legal Definition
A controlled group groups affiliated corporations so the IRS treats them as a single taxpayer for certain tax provisions. This classification forces the members to share limits on deductions, credits, and filing thresholds. The key qualifier is whether ownership exceeds 50% by stock or by a parent‑subsidiary relationship under IRC §1501.
Plain-English Translation
Think of a classroom where a teacher counts every child’s snack as part of the same lunch allowance; the whole class shares the same limit.
Contract relevance
Why controlled group matters in contracts
Misclassifying a group can trigger loss of tax credits or a joint liability for unpaid taxes, and the IRS bears the enforcement risk.

Document context
How controlled group shows up in legal documents
Why does it matter?
Misclassifying a group can trigger loss of tax credits or a joint liability for unpaid taxes, and the IRS bears the enforcement risk.
When does it matter?
When a corporation acquires 80% of another company’s voting stock or a parent‑subsidiary relationship is established, the controlled group status arises.
Where is it usually seen?
Appears in corporate tax returns (Form 1120), Treasury Regulations §1.1502‑1, and in the instructions for Form 8865 for foreign affiliates.
Who is affected?
The parent corporation gains the ability to allocate losses across members; the subsidiary risks being held liable for the parent’s tax deficiencies.
How does it work?
First, the IRS examines stock ownership percentages. Then it evaluates any contractual agreements that create a parent‑subsidiary link. Within 30 days of a qualifying acquisition, the corporation must report the controlled group on its tax return.
