Shortly after takeoff; while accelerating through approximately 180 KIAS; the primary electrical stabilizer pitch trim failed to respond to pitch down trim commands. This condition applied to commands from both the Captain's and Copilot's primary pitch trim switches. The decision was made to return to ZZZ. Landing and taxi was made without further incident.
A Learjet 60 Captain reported the trim stabilizer failed to respond after takeoff resulting in a return to departure airport.
