Narrative:

We pushed back and started both engines knowing that we would need deicing and anti-icing before departing. We received taxi instructions from ground control and taxied to the northern deicing pad. Approximately two minutes after the beginning of taxi we received a call from the rear flight attendant. The flight attendant informed us that the cabin had begun to fill with smoke. At the time the call was received we were still on an active taxiway preparing to turn into the deicing pad. The captain stopped the aircraft and applied the parking brake while [advising] ATC and told ATC that we would need firetrucks. The captain then reached up and turned off both the left and right packs. He called for the smoke QRH and we ran the immediate action items deciding not to apply oxygen masks as we had no smoke or fumes inside of the cockpit. We then proceeded to the smoke QRH. I was reading the checklist and he was completing actions. Once beginning the checklist we quickly realized that it was geared to a smoke emergency in the air.we then decided to open the cockpit door and see if we could find the origin of the smoke. After witnessing the amount of smoke in the cabin the captain called for the evacuation QRH; having the passengers deplane through the main passenger door only. We completed the evacuation QRH and the captain directed me to exit the aircraft and direct passengers while he grabbed the fire extinguisher and moved to the back of the aircraft. Once outside the aircraft I directed passengers behind an ambulance parked 40 to 50 feet away from the aircraft. The flight attendants exited the aircraft after myself and I instructed them to assist me in corralling the passengers. At the time it was both sleeting and raining and the temperature was quite cold.after the smoke cleared the captain and I arranged for shuttle transportation back to the terminal and decided that as a flight crew we would remove jackets and bags and personal belongings from the cabin and return them to the passengers. After communicating with operations; the chief pilot; in-flight and the fire crews; we arranged for a tug to pull the aircraft back to the terminal. At this point all passengers had been bussed back to the main terminal. We received permission from maintenance to start the APU. Both the captain; myself and our 2 flight attendants rode inside the aircraft as it was towed to the terminal.
