Establishing a legal business entity such as an LLC or corporation protects you from being held personally liable if your theatre company is sued. You can form an LLC yourself and pay only the minimal state LLC costs or hire one of the Best LLC Services for a small, additional fee. Recommended: You will need to elect a registered agent for your LLC. LLC formation packages usually include a free year of registered agent services. You can choose to hire a registered agent or act as your own.
