Upon reaching 10;000 [ft.] we ran our 10;000 [ft.] climb checklist; we noted that the pressurization system was not functioning normally and indicated approximately 7;000 [ft.] cabin altitude. We verified all the bleed air system were in the correct position. Shortly after that time we noted that there was smoke/fumes in the cabin. We [advised ATC] and began to turn back to ZZZ and initiate a descent. We ran the Cockpit Smoke Fire Fumes checklist. We intercepted and flew the ILS into Runway 09 at ZZZ and landed without incident.
Lear-55 Captain reported a cabin fumes event during initial climb resulting in a return to the departure airport.
