Reporting Requirements Document


MiFID investment firms subject to the Capital Requirements Directive are required to submit COREP returns. Regulation 33 of S.I. 660 of 2006 outlines the requirements for the following categories of firms:

(A)   Firms who are authorised to deal on their own account or to underwrite on a firm commitment basis, who have a €730k Minimum Initial Capital Requirement, must report to the Bank at least once a month.

(B)   Firms who are not authorised to deal on their own account nor to underwrite on a firm commitment basis, who have a €125k Minimum Initial Capital Requirement, must report to the Bank at least once every three months.  

Firms that are subject to consolidated capital adequacy requirements under Regulation 15 of S.I. No. 661 of 2006 (as amended) - applied to investment firms by Regulation 3(1) of S.I. 660 of 2006 (as amended), must provide information on a consolidated basis to the Bank every 6 months. For a description of relevant applicable templates see the following links:

Reporting requirements for External Auditors

The Central Bank should receive hard copies of management letters produced by a firm’s external auditor following their audit of the financial statements. 

In addition, auditors of MiFID investment firms must make an annual confirmation to the Central Bank as to whether any circumstances have come to their attention that gives rise to a duty to report the matter.

How to Report Returns through the Online Reporting System

Firms are required to submit all returns electronically through the Online Reporting System. Please note that returns from external Auditors are required to be submitted to the Central Bank in hard copy. The following document gives a detailed overview the Online Reporting System.

 Online Reporting System User Manual

The reporting date and submission due date for the majority of returns are set by the Central Bank. However, certain returns are scheduled and submitted by the firm on an Ad hoc basis. This should be completed in line with the following guidelines.

Transaction Reporting

Investment firms have an obligation to report certain transactions in financial instruments to the Central Bank under Section 112 of the European Communities (Markets in Financial Instruments) Regulations, 2007 (S.I. No. 60 of 2007) (as amended).

The Securities & Markets Supervision Division of the Central Bank is responsible for the receipt and monitoring of these transaction reports.

Investment firms that have an obligation to submit transaction reports to the Central Bank should refer to our Transaction Reporting User Guide.

How to Report

Investment firms are required to submit transaction reports electronically on the Central Bank’s online reporting system as soon as possible and no later than the close of the day following the day on which the transaction was executed.

Investment firms can enter data into the Central Bank’s online reporting system either by online entry or by uploading an XML file in the specified format.   The XML Schemas to be used for transaction reporting to the Central Bank are available on this website.

Contents of the Transaction Report

The list of fields requiring completion in a transaction report is set out in our Transaction Reporting User Guide.pdf.

This guide also provides some additional guidelines on how certain fields should be populated and guidelines on how transactions in certain instruments, including over-the-counter derivatives, should be reported.


Where our validation process returns a submitted transaction report due to incorrect completion, this will not constitute the investment firm having satisfied its obligation to submit a transaction report.  The investment firm will only satisfy this obligation when the correct transaction report is received.

Additional Reference Data

Where a transaction is executed on behalf of more than one client, each constituent transaction must be reported and each ultimate client identified. 

Investment firms are required to maintain a single reconciled database of clients, assigning client codes to each client.  This is forwarded to the Central Bank as reference data for interpreting the client codes provided in the transaction report. 

In the absence of such a database, the investment firm is required to provide the full name and address of each client with each transaction.
