Peak Filing Period

Please note that filing of an annual return and its financial statements must be done online. It is not possible to submit paper copies of either document. All returns must be completed online and must also be paid for online. Mandatory e-filing was introduced on 1st June 2017.

After 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. 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 1890-220 226* / 01-8045200 or
- Help with technical or IT issues is available from: 01 804 5355/5374 or
