To answer the question, Triple H has not formally retired from wrestling in WWE. But several people, including Dave Meltzer of the Wrestling Observer Newsletter, believe that his in-ring career is over following his cardiac event - one that was supposedly a major health scare.
''I wouldn’t expect HHH to ever wrestle again, although it is possible he may do one retirement match if he feels the need to leave on his own terms and doctors will clear him, but that’s not likely to be for a long time and he hasn’t even returned to behind-the-scenes work yet.'' said Meltzer
During Triple H's absence after his health scare, NXT 2.0 has been working under the guidance of Shawn Michaels.

Back in April this year, Triple H addressed the idea of saying farewell to his in-ring career for good. Speaking to Sports Nation, Triple H stated that his idea for retirement wouldn't be to have a singles match at WrestleMania but a farewell tour in different parts of the world.
While he admitted that he doesn't need to travel, he said:
"Have that one little farewell tour, make the global loop, then come back and do one big show here and call it a career. That would be interesting to me."
