April 1st is the deadline for biennial reports to be filed in the District of Columbia. All entity types are required to file a report; a $100 late fee is assessed for failing to do so timely. An entity's first biennial report shall be delivered for filing by April 1 of the year following the calendar year in which the domestic filing entity was formed or the foreign filing entity registered to do business in the District. Reports are due biennially (every two years) after that. Additionally, any trade name due to expire this year, must be renewed by April 1st to avoid cancellation.
