Stock exchanges play a critical role in ensuring transparency in securities transactions. One such compliance requirement is the reporting of client code modifications through Form 3BB under the Income-tax framework.

What is Form 3BB?

Form 3BB is a statement required to be furnished by recognized stock exchanges reporting transactions where client codes have been modified after execution of trades.

This reporting requirement is prescribed under:

• Section 285BA of the Income-tax Act, 1961 (Obligation to furnish statement of financial transaction or reportable account)

• Rule 114E of the Income-tax Rules, 1962
