CORE is experiencing one of the busiest days in our year and as a consequence you may experience some degree of processing delay. We apologise for any inconvenience caused.

October Peak

If posting an annual return to the CRO it should be sent to CRO, O’Brien Road, Carlow. The office in Carlow is for receipt of postal lodgements only and is not a public office. Alternatively, presenters can hand deliver to the CRO's Public Office in Parnell Square where you will be provided with a receipt for your documents.

The Public Office is open from 9.30am to 4.30pm. Personal callers are reminded that the queues can be shorter in the Public Office in the morning time and should consider lodging their documents as early as possible to ensure they can be checked and receipts issued on the day. Account holders should ensure that there is enough money in the account to cover the transaction before submitting their documents.


There are over 43,000 companies with an annual return date of 30 September and a filing deadline of 28 October. If you are filing an annual return in respect of one of these companies, you are requested to ensure that your correctly completed return is delivered to the CRO on-time. The best way of doing this is to file on-line.

If you submit your B1 on-line you will have another 28 days from the date of submission to deliver your signature page and financial statements to the CRO. The filing fee for an e-B1 is €20 and for a paper B1 is €40. If an annual return is filed late, late filing penalties apply and, where applicable, the company also loses its entitlement to claim audit exemption in the current year and in the following year.

Should you experience difficulties filing your form on-line:

Help with the content of the form can be obtained from: LoCall 1890-252536* / 059-9178981 / 01-8045394 or The EB1 helpline (01 - 8045394 or 059 9178981) will be open from 9 am to 8 pm on Thursday 27th and Friday 28th of October. Help with technical or IT issues is available from: 01-8045374 / 01 8045307 / 01 8045355 or  

* Note that the rates charged for the use of 1890 (LoCall) numbers may vary among different service providers.

This year, in addition to dealing with the usual peak filing of annual returns in October/ November, the Carlow office will also be responsible for processing applications from companies to be converted to a new company type (LTD or DAC) before the 18 month transition period ends on 30 November.

In the exceptional circumstances pertaining this year, it would be appreciated if instead of telephoning the Carlow office, customers seeking information or assistance could send an e-mail to one of the following e-mail addresses, please:

Annual Returns:  
e-B1 queries:  
Business Names:  
District Court:  
Credit Card Refunds:  
Customer Accounts:  

Please note that on the CRO website, in the "WHAT'S NEW" section, there is a daily update advising of the date of receipt of annual returns, RBNs and conversion documents being processed on that day. Customers should, where at all possible, avoid contacting CRO about documents delivered after the processing date given on the website as they have not yet been reached by the processing team. This will allow CRO to continue to dedicate resources to the processing of submissions. Your cooperation in this regard would be greatly appreciated.
