B3 created an automatic Income Tax (IR) withholding transaction for CFF – Closed-End Fund Shares. If the IR withholding transaction for CFF is entered before 10.00 AM, the event settlement message will be sent in Gross settlement mode with the tax amount already withheld.  On the other hand, if the IR withholding transaction is entered after 10:00 AM or the event is entered in T0, the flow will be the same as that currently adopted. In other words, two messages will be generated: one with the full amount of the event and one with the amount to be withheld from IR.
