Since the establishment of Liga 3 as the third-tier league, Sumut United has reached the final once, in the 2022 Liga 3 final, where they drew 3–3 in normal time and won 4–2 in a penalty shoot-out against Putra Delta Sidoarjo.[2] At that time, they were still known as Karo United.
The final will be played as a single match. If tied after regulation time, extra time and, if necessary, a penalty shoot-out will be used to decide the winning team.[3]
