As Boca Juniors and Huracán both finished with 51 points each, they had to play a best-of-three playoff to decide a champion. Palermo, which had been relegated from the Asociación Amateur, joined Asociación Argentina remaining at Primera División. Argentino de Quilmes returned to the top division after being relegated in 1918, while All Boys, Argentino de Banfield, and Sportivo Villa Urquiza made their debuts in Primera.[2]
After Boca Juniors and Huracán finished tied on points, a two-legged series was established to define a champion.

With the third match drawn on points (there was no goal difference rule), a playoff was held, finishing 0–0 after extra time so a fourth match –to be played to a finish– was required to determine a champion.
