There are 20 clubs in the Iraqi Premier League. During the course of a season (from September to May) each club plays the others twice (a double round-robin system), once at their home stadium and once at that of their opponents, for a total of 38 games (however, all matches between Baghdads Big Four clubs are played at the neutral venue of Al-Shaab Stadium to accommodate more spectators at the big games). Teams receive three points for a win and one point for a draw. No points are awarded for a loss. Teams are ranked by total points, then goal difference, and then goals scored. If still equal, teams are deemed to occupy the same position. If there is a tie for the championship, for relegation, or for qualification to other competitions, a play-off match at a neutral venue decides rank. The three lowest placed teams are relegated into the Iraq Division One, and the top three teams from the Iraq Division One are promoted in their place. Each club is allowed a maximum of three foreign players in their squad. The winners of the league qualify for the Al-Muthabara Cup, a match played against the winners of the Iraq FA Cup (if the league winners also win the Iraq FA Cup, they play the league runners-up instead).
