Annual Accounts FAQs

When is my B1 annual return due?

Your B1 is due 56 days after your Annual Return Date (ARD). The ARD is typically 6 months after your company incorporation date for the first return, and annually thereafter. Finlay Mulligan tracks your ARD and files well ahead of the deadline.

What happens if I miss my CRO filing deadline?

CRO charges EUR 100 immediately, then EUR 3 per day up to a maximum of EUR 1,200. More critically, your audit exemption is at risk of being lost for two years if you are late more than once in a five-year period — meaning statutory audit becomes mandatory. We ensure this never happens.

What is iXBRL and do I need it?

iXBRL (Inline XBRL) is a machine-readable format Revenue requires for financial statements filed with CT1 returns. All companies using electronic filing must tag their accounts. We handle all iXBRL tagging as part of the service.

Can I claim audit exemption?

Most Irish private limited companies qualify for audit exemption if they do not exceed two of three size criteria for the current and preceding year: balance sheet under EUR 7.5m, turnover under EUR 15m, fewer than 50 employees. We confirm your eligibility and maintain the exemption.

How long after my year-end do I have to file?

CT1 is due on or before the 23rd of the 9th month after your accounting year end. Preliminary corporation tax is due by the 11th month of the accounting year itself for small companies, or in two instalments (6th and 11th month) for large companies. We plan for both dates to help ensure cash is available for tax payments.
