Tips and pointers for the busy filing season
Important dates
For the majority of Irish companies, the following timelines apply:
For a financial year end date of 31st December, the 30th September is the Annual Return Date (ARD)
Therefore, by Tuesday 25 November, 56 days from the ARD, the company’s Annual Return, financial statements and signed signature page should be electronically filed (only-no manual filing is permitted).

File early!
We would encourage presenters to file early if at all possible. Do not leave filing till the last minute. The Companies Registration Office’s (CRO) position on timing of receipt of a document is when it has been received by the CRO and not when it has been sent by you or your agent. Therefore, if there are delays in the system which result in the documents being received after midnight on 25th November then the document is late even if it had been sent before midnight.
Also, early filing will help to avoid problems with potential CRO systems and resource deficiencies. At a stakeholder meeting with the CRO on 3rd September 2025 the CRO reported that it has a backlog of 20,000 B1’s to process. They estimate that this is a 6-week backlog. They anticipate that this will reduce by the beginning of peak filing season, but early filing may mitigate potential difficulties and delays.

Please note that the Companies Registration Office (CRO) will not accept electronically signed documents. The signature page(s) must be physically signed i.e. “wet ink” and then scanned for submission.
If you require help with CORE or have technical issues with filing your annual return, please contact the CRO Helpdesk support@cro-helpdesk.cloud.gov.ie. Agents who use software packages should contact their software vendor directly for information in relation to technical issues, such as upgrades of these systems. All other queries for Annual Returns can be directed to the dedicated mailbox CRO Annual Returns annualreturns@cro.ie
