Narrative:

Shortly after takeoff; after retracting gear and flaps; we received an amber cas message 'hydraulic vol low'. I immediately directed the sic/pilot monitoring to put the gear down. We told departure we had to return to the airport; and declared an emergency. The pilot monitoring ran the checklist; and we finished the checklist. We landed uneventfully; but had to use the emergency (pneumatic) braking system since we lost all hydraulic functions including brakes; anti-skid; thrust reversers; and spoilers/spoilerons. We had enough emergency nose wheel steering to exit the runway and stopped on a taxiway; where two fire trucks met us. We were then towed to the FBO. There was a large amount of hydraulic fluid dripping from the aircraft; and there appeared to have been a leak from the nose gear compartment.
