Tsoumagas started his career with his local side Edessaikos when he was 17 years old. Although he did not play for the club's men's team, he attracted many scouters with his talent, and in 2009, Superleague side Asteras Tripolis signed him for their U-20 squad. After promoting him from the youth squad to the men's outfit in 2010, Asteras Tripolis immediately loaned Tsoumagas to Gamma Ethniki side Zakynthos on a season-long deal. During his loan spell with Zakynthos, Tsoumagas played in 18 matches. After his loan spell ended, he managed to play one game with Asteras Tripolis during the 2011–2012 season, and was subsequently released from his contract at the end of the season.
In 2012, Tsoumagas moved to Portugal and signed with LigaPro side Leixões. He featured in 16 games during the first half of the season for the Portuguese club, before moving to struggling Greek giants AEK Athens in January 2013, as a free agent. During a 5-month stay in Athens, Tsoumagas featured in 13 Superleague games. After the club's relegation to the 3rd Division due to financial issues and attempt at a restart, Tsoumagas renewed his contract for the next four years. He played with AEK in the Gamma Ethniki and helped the club achieve an easy 1st place finish in the 6th group. His contract was subsequently terminated on June 2, 2014. Tsoumagas went on to play for fellow Gamma Ethniki side Panelefsiniakos, where he featured in 8 matches and scored one goal, before moving to the 2nd division and signing for Pierikos.
In August 2015, Tsoumagas returned to Portugal signing for Portuguese Third Division side Vianense. On July 3, 2016 Tsoumagas once again returned to Greece, signing a contract with Gamma Ethniki side Ergotelis. He terminated his contract with the club on mutual consent on 23 December 2016.
