Format
The tournament consists of a double round-robin format, in which all twelve teams play each other twice, with classification split in two stages. Each round counts as one stage.

The better-placed teams of each stage will face themselves in a two-legged tie, with the team with the most points in the overall classification playing the second leg home, the winning team will then be declared champion. In case of a tie in number of points and goal balance, the advantage is for the best campaign team. If the same team is best-placed on both stages, it will automatically be declared champion.

The best two-placed teams in the overall classification not advancing to the finals and not from Curitiba will face themselves in a two-legged tie competing for the Torneio do Interior. The team with the most points will play the second leg home. The bottom two teams on overall classification will be relegated.
