A controlled group in corporate taxation is characterized by a collection of corporations that share management control. This means that one or more entities possess a significant degree of control over the operations and decisions of the other corporations in the group. The Internal Revenue Code provides specific rules for defining these relationships, primarily focusing on ownership percentages and voting control.

When a group of corporations qualifies as a controlled group, it can have important implications for tax treatment, including limitations on deductions, credits, and the application of certain tax regulations. This concept ensures that entities that are closely related in terms of ownership and management are treated as a single unit for tax purposes, preventing manipulation of tax liabilities across different entities.

In contrast, the other options do not accurately define a controlled group. A group of unrelated corporations would lack the necessary control and ownership relationships that define a controlled group. A conglomerate of various industries does not inherently imply management control over the corporations involved. Lastly, a group facing no tax limitations does not accurately reflect the specific regulatory environment that applies to controlled groups, which often includes various tax compliance requirements.
