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.
