DTCC Direct Debit for Transaction, Membership, and Session Fees

Beginning in May 2024 for the April billing cycle, Direct Debit via DTCC (“Direct Debit”) is the default payment method for Exchange fees.

The Exchange will send monthly electronic invoices, generally by the fifth business day of each month, for fees or rebates generated in the prior month.

The Exchange will subsequently initiate the debit of any fees due to the Exchange for the prior month on or about the 15th day of the month.

Firms can dispute an invoice in writing by the 15th of the month or the following business day if the 15th is not a business day. If the disputed amount is $10,000 or greater, the Exchange will not include the disputed amount in the debit pending resolution of the dispute.

Credit balances will be paid by the Exchange via wire transfer.

Firms may opt out of Direct Debit by completing this form and returning it to [email protected]

Firms with multiple MPIDs must contact [email protected] to establish a default billing MPID and associated DTCC number, from which firm level fees will be collected.
