From 1972-90 Kallas was a member of the CPSU (Communist Party of the Soviet Union). In 1987, Kallas was one of the authors of the IME plan for self-managing Estonia with Tiit Made, Edgar Savisaar and Mikk Titma. The plan proposed to make Estonia economically independent from the Soviet Union – adopting a market economy and establishing Estonia’s own currency and tax system.[2] Kallas was elected a member of the Congress of People's Deputies of the Soviet Union in the 1989 Soviet Union legislative election, the first partially free elections in the Soviet Union.
After Estonia restored its independence in 1991, Kallas was appointed the President of the Bank of Estonia, which at the time had only 11 employees. Within a year a coherent structure of the bank was set up and on 20 June 1992, Estonia's own currency Kroon was back in circulation after being removed from circulation by the Soviets on 25 March 1941.[2]
After leaving the European Commission, Kallas ran in the Estonian presidential election in 2016, but was not elected. In October 2017, he started as the municipal mayor of Viimsi Parish.[5] In 2019 he was elected member of the Riigikogu, a post he was also elected to in 2023.[6][7] He resigned as a member of Riigikogu and from politics in September 2024.[8][9]
His daughter, Kaja Kallas, was the prime minister of Estonia from 2021 to 2024.
Kallas is married to doctor Kristi Kallas, who, during the Soviet deportations from Estonia, at age six months, was deported to Siberia with her mother and grandmother in a cattle car and lived there until she was 10 years old.[11]
He has one son and one daughter. His daughter Kaja Kallas was the leader of the Reform party and was the prime minister of Estonia from 2021 to 2024.[12]
