Peñarol were the champions after winning the Torneo Clausura and defeating Apertura winners Defensor Sporting at the championship playoff via penalty shoot-out.
Also, the Torneo Intermedio winners would qualify for the 2018 Copa Sudamericana in case they failed to secure an international berth at the end of the season.
The Intermedio winner also had the chance to play the Supercopa Uruguaya against the Primera División champion.
Since Peñarol and Defensor Sporting ended the season tied in points, a playoff was played to determine the aggregate table first-placed team.
Since Peñarol, who had the best record in the aggregate table, won the semifinal, they became champions automatically and the final was not played.
