Can a limited liability company be the sole member of a limited liability company?

Yes, a limited liability company (LLC) can be the sole member of another LLC. This structure is often used for various purposes, including liability protection, tax benefits, and organizational flexibility. The parent LLC would own 100% of the subsidiary LLC, allowing it to control its operations and assets while maintaining limited liability protections. However, specific regulations may vary by state, so it's important to consult local laws.
