The Maryland Disclosure of Corporate Interest (also known as the Statement of Corporate Interests) is a required filing with the Maryland State Department of Assessments and Taxation (SEAT) for any person or entity that owns 50% or more of a Maryland Corporation or LLC, or who exercises control over it. The purpose of the filing is to identify those individuals who are in control of the company, and to provide a public record of that information. There are three types of Maryland Disclosure of Corporate Interests: initial filing, annual filing, and amended filing. An Initial filing must be made within 60 days of forming a Maryland Corporation or LLC. An annual filing must be made each year before April 15th in order to maintain the entity’s good standing. An amended filing must be made if any of the information on the initial or annual filing has changed. The filing must include the names and addresses of the corporate officers, directors, and shareholders, any mortgage or security interests, and the names of all creditors.
