Aircraft
We made a soft landing and were [about] to exit at the very end. Just as we were about the last third of the runway; the cabin called. The First Officer was told that we had smoke in the cabin; they couldn't clearly see each other; and reported a coughing passenger. I instructed the First Officer to notify the Tower; to request they send the fire trucks to meet us and [request priority]. As we were seconds from the gate and considering the possibility of having a fire onboard; we agreed that an evacuation was necessary. I decided to bring the aircraft [to a stop] quickly at 30 feet (safe distance) from the gate and started an evacuation using the Evacuation Checklist. The ramp personnel were in position and able to assist the passengers along with the flight crew. All passengers were regrouped and instructed to walk up the jet bridge and gather inside to safety. Following the inspection from the fire department that arrived within 5 to 10 minutes; I contacted and notified the Company; Operations; and Maintenance. During this entire process; we received full assistance of all parties involved.
CRJ-900 Captain reported evacuating the aircraft on a taxiway after smoke was reported in the cabin.
