CBIC Chairman Sanjay Kumar Agarwal (IRS C&IT: 1988 batch) and two other senior members (Shashank Priya and Surjit Bhujbal) retired, ending months of speculation about tenure extensions. This has triggered expectations of a major leadership reshuffle in CBIC, potentially affecting IRS (Customs & Indirect Taxes) officers in GST, Customs, Excise, and DRI roles. The government is expected to appoint successors soon, with focus on strengthening anti-smuggling and GST enforcement.
