Teams placed 1st to 6th at the end of the regular season automatically qualified for the playoffs quarterfinal round.
The remaining two spots for the playoffs quarterfinal round were determined through a four-team play-in. The 7th and 8th-placed teams had to play a single-game round against the Second League 2nd and 1st-placed teams, respectively, that managed to gain promotion for the next season's top league competition. Seventh-placed Partizan from the First League thus played 2nd-placed Sloga Kraljevo from the Second League. Similarly, 8th-placed Budućnost from the First League played 1st-placed Radnički Belgrade from the Second League. The winners of each respective game qualified for the playoffs quarterfinal.
