AI summary

ICICI Bank received a show cause notice on September 30, 2026 from the CGST Mumbai East Commissionerate demanding about Rs 229.14 crore in GST plus interest and penalty. The demand relates to services offered to customers maintaining minimum balances in their accounts. The bank is already in litigation, including a writ petition, on similar past orders. It will file a reply within the prescribed timeline and has disclosed the matter only because the amount crosses the materiality threshold.

Likely market impact

Tax demand is modest relative to bank size. Bank is contesting similar past issues, so the final hit is likely small; limited near-term stock impact expected.
