Online Filing

An annual return can be completed online using 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 56 days from your Annual Return Date to file your return online and to get the signature page, financial statements and payment to CRO.

Please see video for help on efiling a annual return (B1 Form):  

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 56 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

Since 1st April 2018, B1’s will be automatically rejected where the B1 signature page or overall certificate is not signed or if it has only one signature. A new annual return must be captured, financial statements uploaded and a new signed signature page delivered to the CRO. Where this new annual return is more than 56 days after the company’s Annual Return Date the B1 will be late.

Since 1st April 2018, Financial Statements must be uploaded prior to sending in a signed signature page to the CRO. If a signature page is received and there are no financial statements uploaded then this annual return will be rejected. Companies will not be given 14 days to upload the financial statements.

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

We have made some changes 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 

The CRO introduced mandatory electronic filing for the submission of the following documents (since 1 June 2017) in accordance with S.I. No. 458 of 2016 and Section 897, Companies Act 2014:

Q 2: If I have a paper B1 and paper financial statements both signed before 1 June 2017, can I deliver them to the CRO after 1 June 2017.
A: No, under the terms of the Statutory Instrument (No. 458 of 2016), from 1 June 2017 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:

  • 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 rejected.

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.
