The Central Depository Services (India) Limited (CDSL) on October 9, 2026, announced a revised stamp duty validation mechanism for Invocation-cum-Early Pay-in (EP) transactions through its communiqué dated October 9, 2026. The revised mechanism aims to prevent transaction failures during obligation matching due to insufficient stamp duty balances.
Under the revised process, CDSL will verify stamp duty availability at the time of transaction setup. Transactions with insufficient balances in the virtual bank account of the Pledgee Beneficial Owner (BO) or Depository Participant (DP), as applicable, will be rejected upfront with the reason “Insufficient stamp duty amount.” Where sufficient funds are available, the required stamp duty will be blocked at setup and debited proportionately to the matched quantity during obligation matching. Any excess blocked amount will be released after obligation matching, and no “overdue” status will be generated due to insufficient stamp duty for these transactions.
The revised operational mechanism was scheduled for release on October 9, 2026, and became effective from October 10, 2026. DPs are required to inform their Trading Member (TM) and Clearing Member (CM) clients. No changes are required to DP back-office systems or processes.
