Narrative:

On climb out passing through 11;000 the airframe began accumulating ice. The boots were activated and shortly afterwards; the airplane pitched down. The autopilot pitched the nose up and the nose pitched down again. The autopilot was turned off and a request was made to return to the airport. ATC vectored us onto the ILS and advised the tower would be closing in three minutes. ATC cleared us for the approach and advised to cancel the IFR clearance when able. Upon landing we taxied to the ramp and debriefed the incident with the ice. I then received a phone call from our ramp employee who had received a phone call from seattle center asking if we were on the ground. I called seattle center and advised we were on the ground. I had landed and forgot to notify center that we were on the ground in a timely manner.
