Changes from last season

 * 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, ISL clubs will not be eligible for a slot in the AFC Champions League; instead, the league premiers will qualify for the AFC Cup group stage, rebranded as AFC Champions League Two.


 * This season, defending League Shield winners wear the champions badge instead of the defending cup winners.


 * In May 2023, the South Asian Football Federation Ordinary Congress decided to hold the inaugural SAFF Club Championship. The two teams that finish the highest in the 2023-24 Indian Super League table and have not qualified for the AFC Champions League Two or AFC Challenge League will represent India.
