The man identified as Zakaria J "has been charged with terrorist murders and participation into the activities of a terrorist group," the prosecutor's office said in a statement.
French President Francois Hollande has said that the Paris attacks were planned in Syria but prepared and organized in Belgium. The Islamic State group has claimed responsibility for the attacks.
Earlier this month the authorities announced that Belgian police have identified three safe houses used by key suspects including presumed ringleader Abdelhamid Abaaoud, a Molenbeek resident who was killed in a French police raid days after the Paris attacks.
The premises include a flat in Charleroi, a town south of the capital Brussels where a major airport is located, a house in the rural village of Auvelais near the French border, and a flat in Brussels.
The Belgian authorities have formally charged 11 people in the case, including a number from Molenbeek.
Four suspects remain at large, including Salah Abdeslam who allegedly drove suicide bombers to the French national stadium outside Paris, as well as Mohamed Abrini, suspected of having helped scout out the attack sites.
Both are from Molenbeek.
