The 34-year-old Swede, who joined the club in 2012 from AC Milan and has scored 127 goals in 156 games since then, now gets €1.5 million ($1.6 million) a month before tax under the performance-based hike agreed late last year.
On top, Ibrahimovic can pocket three big bonus payments for winning the Champions league, the French league title and and ending the season with the top combined total of goals scored and goal assists.
With Paris Saint-Germain currently 21 points clear of second-placed Monaco in the league, the first of those targets is all but certain. Paris go up against Chelsea in the last 16 of the Champion League next month.
Le Parisien added, however, that there was no word on whether Ibrahimovic would stay in Paris after his current contract expires at the end of the season.
He is on record as saying he has no intention of leaving, claiming he has "a beautiful relationship with PSG."
Ibrahimovic will be playing in France during the summer as Sweden contest the Euro 2016 finals
