Can an LLC own another LLC?

Yes, an LLC can own another LLC.

This is called a parent-subsidiary structure or holding company arrangement. The parent LLC becomes a member of the subsidiary LLC. This structure provides liability isolation between business units, tax planning flexibility, and asset protection. Each LLC maintains its own EIN, bank account, and operating agreement. The subsidiary's operating agreement lists the parent LLC as a member. There is no limit to how many LLCs a parent can own. Common uses include separating real estate properties, isolating high-risk operations, and organizing multiple business lines under one umbrella. Ensure each entity maintains proper formalities (separate records, no commingling of funds) to preserve the liability shield between entities.
