Online Filing

An annual return can be completed online using https://core.cro.ie. An annual return can also be filed online using a secretarial software package. An annual return can be filed through CORE for €20. You have 28 days from your Annual Return Date to file your return online. You then have a further 28 days from the date you file online to get the signature page, financial statements and payment to CRO.

Please see video for help on efiling a annual return (B1 Form): https://www.youtube.com/c/croirl  

Please note that the CRO Public Office is based in Gloucester Place Lower, Dublin 1, on the corner with Sean MacDermott Street.

Where an annual return is e-filed but the submission is not completed within the concessionary period of 28 days i.e. the appropriate financial statements, signature page and relevant filing fee are not delivered to the CRO, this office reserves the right to block further e-filings of the same submission by the company and may insist on the annual return being filed in hard copy when it is being re-submitted.

Why can I not see all my submissions in my CORE Workspace?

We have made some changes recently to make CORE more efficient, one of these changes is to limit the number of drafts in a user's workspace to the last 100 days. However, nothing is deleted or lost. If a user wants to recover a submission before that date then they just need to enter the company number or submission number in the search bar just above the workspace drafts. This will recover anything beyond the most recent 100 days.

Mandatory E-Filing Required since June 2017

Frequently Asked Questions on Mandatory Electronic Filing

Q 1: What is the Legal Basis for the introduction of mandatory e-filing of annual returns and financial statements? 
A: The Legal Basis for mandatory Electronic filing of form B1s, B73’s, B2s, and B10s is under Statutory Instrument No. 458 of 2016 and Section 897, Companies Act 2014 - see SI 456 of 2016 on the Irish Statute Book website and Companies Act 2014 on the Irish Statute Book Website.

Q 2: If I have a paper B1 and paper financial statements both signed before 1 June, can I deliver them to the CRO after 1 June.
A: No, under the terms of the Statutory Instrument (No. 458 of 2016), from 1 June the sole means to be used to deliver a B1 is in electronic format. If you are planning to deliver an annual return to the CRO on or after 1 June, you must:

  • Submit the B1 on CORE or on a software package,
  • upload the financial statements as a PDF; and,
  • pay the fee by credit/debit card or Customer Account
  • Where a signature page is required deliver the signature page to the CRO on or after 1 June, 2017.

Q 3: Is it possible to file paper copies of Financial Statements. 
A: No. Hard copies of the financial statements will not be accepted by the CRO on or after 1 June, 2017.

  • All Financial Statements must be uploaded as a PDF either on CORE or on a software packages on or within 28 days of the captured of the E-B1. The PDF of the financial statements can be attached to the E-B1 in your Workspace in CORE or in the other software packages, in much the same way as you attach a document to an e-mail.
  • The B1 signature page must not be delivered to the CRO until AFTER the financial statements have been uploaded as a PDF.
  • If the financial statements have not already been uploaded when the signature page is received in the CRO, an email will issue to the Presenter informing them that their document is sent back and that they must resubmit their B1, upload their financial statements, print and sign a new signature page and deliver it to the CRO within 14 days. Companies and Presenters should ensure that they provide the correct email addresses to ensure they are alerted when their documents are sent back as they will no longer receive a letter or documents by post. 

Q 4: How can the B1 form be signed? 
A: The B1 form can be signed digitally using a Revenue Online Service (ROS) certificate or can be signed using a signature page. The signature page is available after the B1 form has been submitted electronically and must be printed, signed and delivered to the CRO within 28 days of submitting the form online.

Q 5: Can an Electronic Filing Agent sign the B1 form? 
A: Yes, an Electronic Filing Agent (EFA) can sign a B1 form using ROS on behalf of a company they are agents of. Where the EFA signs the B1 instead of the director and secretary an EFA cannot certify the financial statements on behalf of the company. The overall certification for the financial statements must be signed by the director and secretary and is required to be delivered to the CRO within 28 days.

Q 6: Is it possible to send in a cheque with the signature page? 
A: No. You must pay by Debit/Credit card or by CRO customer account. You may, however, top up your customer account using a cheque.

Q 7: How do I open a CRO Customer account? 
A: There are two ways to open an Account;

1. Accounts can be opened online on www.cro.ie - https://search.cro.ie/company/NewCustomer.aspx
2. Accounts can be opened using an A/c1 form a form can be printed from Opening a Deposit Account page and it is possible to fill out this form before it is printed. Send the completed form to the Customer Accounts Section, CRO, O’Brien Road, Carlow.

Q 8: If my Annual Return Date (ARD) falls before 1 June, can I file a paper B1 and paper financial statements after 1 June. 
A: No, the ARD has no bearing on the matter – under the SI, it is the date of delivery of the annual return that dictates the method of delivery and the SI states that from 1 June, the sole means to be used to deliver a B1 shall be in electronic form.

Q 9: Do Financial Statements need manuscript signatures? 
A: Financial statements presented to the CRO do not need to carry the manuscript signatures of Directors or Auditors. Instead, financial statements filed with the CRO must contain:

  • the typed name(s) of the Director(s) who signed the financial statements on behalf of the Board of Directors,
  • the typed name of the Auditor (where applicable), and
  • The date each document was signed on.
  • The financial statements must be certified by a director and secretary of the company. The certification is contained in the B1 form however a separate overall certification is required where an Electronic Filing Agent has signed the B1.

Q 10: Will I be able to file concurrently online via CORE all outstanding annual returns for a restoration application and generate a number of signature pages for signing and return to the CRO by post?

A: Yes, the facility to file multiple form B1's electronically for consecutive years is available.

Will a presenter be able to complete both online?

A: Yes, the facility to file multiple form B1's electronically for consecutive years is available.

Q 13: Can I use a B1U to file group financial statements after 1st June 2016?

An email will issue to the Presenter informing them that their document is sent back and that they must resubmit their B1, re-upload their financial statements, print and sign a new signature page and deliver it to the CRO within 14 days.
