Narrative:

I was the second-in-command and pilot not flying on this leg. The weather was 2;000 overcast with moderate mixed icing reported. We had flown two previous legs earlier on this day using our engine anti-ice; wing anti-ice; and the horizontal stab deice with no abnormalities. The anti-ice/deice systems all checked out on the ground.we were cleared for takeoff and at 400 ft the captain called for flaps zero. We turned to a heading assigned by tower; and I turned on all the anti-ice/deice systems. We immediately got an 'hstab ice fail' light. The captain requested an immediate return to the airport. We declared an emergency and requested an altitude of 2;000 ft; which would keep us out of the clouds. I informed our two passengers that we would be making an immediate landing because we had lost our deicing protection. I accomplished the horizontal stabilizer ice protection system failure checklist. I then accomplished the flaps 10 approach and landing procedure checklist.we landed at flaps 10 without further problems.
