What are the filing deadlines I need to be aware of for my Irish limited company?

As a director of an Irish limited company, you must observe the following important filing deadlines:

  • Annual Return:
    • First Annual Return: Due 6 months after the company’s incorporation.
    • Subsequent Annual Returns: Annually, within 56 days of the so-called ‘Annual Return Date’ (ARD).
  • VAT Return: Usually every two months, depending on turnover and registration status.
  • Corporation Tax Return (Form CT1): No later than 9 months after the end of the financial year, but no later than the 23rd day of the ninth month.
