Narrative:

The incident involved a planned flight was from ZZZ to ZZZ1. After preflighting; I started the aircraft at about xa:45pm and taxied out to the run-up area for an IFR departure on runway xx. I picked up our clearance and accomplished the engine run-up; which was normal. The clearance was to fly heading 270; then direct ZZZ2; climb and maintain 3;000 ft. The takeoff roll was normal and initial climb out appeared normal until about 200-300 ft. When smoke started entering the cockpit via the pilot's side defrost vent. After noticing this; I informed my passenger; and started a tight crosswind turn; anticipating an immediate landing at ZZZ. I elected not to check in with ATC and handle them once I was on the ground. On downwind; I made sure that the defrost vents were closed. Smoke continued to enter. I then shutoff the master switch; thinking the smoke could be electrically related. Smoke continued. I then turned the master back on and extended the landing gear. Progressing from downwind to base to final; the smoke decreased and appeared to stop. We landed otherwise uneventfully on runway xx. As we were exiting the runway; the engine began to run rough. Immediately after exiting the runway; the engine stopped running and smoke began billowing out of the cowl. We evacuated the aircraft.
