On 14 February 2016, having been deemed surplus to requirements by new manager José Peseiro, Maicon was loaned to São Paulo FC; upon arriving, he stated that the move was "a dream come true". He made his debut in the Campeonato Paulista on 1 March in a 2–0 home victory against Mogi Mirim Esporte Clube. On 2 April, he missed a penalty before scoring the last-minute winner in a 2–1 win over Oeste Futebol Clube at the "Estádio do Morumbi".
