Twenty teams competed in the tournament, twelve returning from the 2020 season, four promoted from the 2020 Campeonato Brasileiro Série C (Brusque, Londrina, Remo and Vila Nova), and four relegated from the 2020 Campeonato Brasileiro Série A (Botafogo, Coritiba, Goiás and Vasco da Gama).
Brusque were deducted three points after they were punished by Superior Tribunal de Justiça Desportiva (STJD) for racial abuse aimed toward Londrina's player Celsinho during the match Brusque v Londrina, played on 28 August (21st round). Brusque also were sanctioned with a fine of R$60,000. On 18 November 2021, STJD overturned its decision and the three points were returned to Brusque.
The top four teams were promoted to the 2022 Campeonato Brasileiro Série A. Botafogo and Coritiba became the first two clubs to be promoted on 15 November 2021 after a 2–1 win against Operário Ferroviário and a 1–0 Brusque win against CRB, respectively. Goiás were promoted on 22 November 2021 and Avaí on 28 November 2021.
