"My focus right now is solely on finishing this season as strong as possible with the Mavericks," Parsons told ESPN's Tim MacMahon. "It'd be selfish of me and a disservice to this franchise and to my teammates to be thinking about this summer when we have a chance to do something special."
Parsons, who can opt out of his contract this summer, then put his foot down when pressed on the issue.
"You have a calendar? This isn't July. Call me then, if you want to talk about free agency."
Parsons is expected to be pursued by several teams, but his hometown Orlando Magic will do so "aggressively," sources told MacMahon. Orlando has cleared enough cap space to sign two max players.
Parsons signed a three-year, $46-million contract with Dallas in 2014 with a player option in the final season. It is a virtual certainty he opts out - not only because of the rising salary cap, but because the forward has been playing excellent basketball in the wake of knee surgery last spring.
Parsons has averaged 17.4 points and 5.3 rebounds per game on 46 percent 3-point shooting since Jan. 1, as the surprising Mavericks continue to loiter in the top eight of the Western Conference.
Parsons grew up in the Orlando area and later went north to Gainesville to attend the University of Florida. On the flip side, he is also known to be close with Mavs owner Mark Cuban, and Dirk Nowitzki took a steep pay cut in the summer of 2014 in part so the team could afford Parsons.
