This list details Milan's achievements in major competitions, together with the top scorers for each season.
By the end of the 1980s, the club had managed to become successful again and, in the 1991–92 season, they went on to win the championship unbeaten (a feature that was never achieved before in Serie A).
^ Before the establishment of the modern Serie A in 1929, the championship was contested under several different formats, including knock-out competitions or successive group stages.
^ The Coppa Italia was founded in 1922, but – despite an abortive attempt in 1927 – a second edition did not take place before the 1935–36 season.
Since then the tournament was played on a regular basis until 1943, when it was suspended due to World War II.
C. ^ Goals in all official competitions (league, domestic cup, European and others) are counted.
E. ^ Milan, along with other major clubs, did not enter the league in 1908 due to a dispute with the Italian FA over the use of foreign players.

S. ^ Joint top scorer with Paolo Pulici of Torino and Giuseppe Savoldi of Bologna.
W. ^ Milan received a one-year ban from UEFA competitions due to unsporting behaviour.
