Proof of deposits are only required if requested. Upon receipt, IBKR will review your payment for credit and notify you if proof of payment is required.
Please allow your payment to arrive at IBKR which may take from immediate up to 4 business days depending on the currency, transfer method, sending bank location and value date your bank processed your payment. If we require you to provide a proof of payment, we will post in Client Portal under the Notifications (bell) icon.
