This was the first season where the promoted I-League winner competed, thereby increasing the number of participating teams to 12. Punjab FC was promoted to the Indian Super League by winning the 2022–23 I-League.
The league was played around eight months for the first time, primarily due to the breaks taken during the 2023 AFC Asian Cup and 2026 World Cup qualification matches.
As per the new AFC Club Competitions Ranking structure,[8] ISL clubs will not be eligible for a slot in the AFC Champions League; instead, the league champions will qualify for the AFC Cup group stage, rebranded as AFC Champions League Two.
From this season onwards, defending League Shield winners wear the champions badge instead of the defending cup winners.
From this season onwards, no star is used in the tournament logo of the club jersey based on the number of ISL title of that club.
