In this model, the members enjoy limited liability and the LLC itself has perpetual existence. Additionally, members enjoy the benefits of flow-through taxation, unless they elect otherwise, or have too many corporate characteristics. Most jurisdictions also require fewer formalities in forming and operating an LLC.
