In 2011, after another poor showing of AGP in the state assembly election he along with some of his colleagues started a reform process of the party. His initiatives were supported by many leading intellectuals of the state. However, he failed to motivate the top leadership to reform and restructure the party. In frustration, some of his colleagues left the AGP and joined other political parties. Jagadish Bhuyan too resigned from the primary membership of AGP and joined the Bharatiya Janata Party. He is currently the executive member of BJP, Assam Pradesh.
On June 7, 2015, after stating "I have lost faith in the AGP which has become directionless and was shrinking each passing day. The BJP on the other hand is the right party to fight for the cause of Assam..." Jagadish Bhuyan along with several senior members of the AGP from Tinsukia district joined the BJP.
While he was in the BJP he was one of the Media panelists of the party. He was the Chairman of Assam Petrochemicals Limited with Cabinet Rank.

Jagadish Bhuyan told media "When I saw the revised CAA was against Assamese people, I decided to quit. From now I will take part in anti-citizen law protests".
