Speaking to reporters, the CEA said that he had the best job and "also the best job I will ever have".
"I will go back with best of memories. I will always be committed to serving the country at all times in future," he said, adding that in Jaitley he had a "dream boss".
Subramanian was appointed as CEA to the finance ministry on October 16, 2014 for a period of three years. In 2017, his term was extended for a year.
The process of finding his successor will start soon, he said.
"His reasons were personal but extremely important for him. He left me with no option but to agree with him," Jaitley wrote in a Facebook post.
During his tenure, Subramanian came out with futuristic ideas on rationalisation of removal of "subsidies for the rich", universal basic income, climate change, and the four C's -- courts, CAG, CVC and CBI which had historically paralysed decision making.
He also conducted the first online course on Indian economy for the benefits of students and teachers across the country.
Besides, he launched the government’s online education platform 'Swayam', which became one of the most followed courses in India. PTI DP NKD CS SA
