Airport; Weather
After completing a normal approach and landing on Runway XX in ZZZ we taxied via K and crossed Runway XY and XZ. As we crossed Runway XZ tower cleared us into the ramp with him. We saw a Falcon taxing out and elected to turn right onto Taxiway A and enter the ramp via N. Upon slowly turning onto Taxiway A; we hit a sold sheet of ice on the taxiway. As I tried normal braking; the aircraft kept sliding uncontrollably through N. I then tried emergency braking still unable to stop the aircraft. We slowly went off the west side of the taxiway 180 degrees into the grass. The passengers and flight crew were not injured and performed a safely evacuation. My First Officer during the event notified tower of the situation and reported baking action NIL. Notams in ZZZ REPORTED that all taxiways had ice and braking action POOR.
[Report narrative contained no additional information.]
EMB-505 flight crew reported that ice on a taxiway surface resulted in a taxiway excursion.
