How to find your company's annual return date

Quick answer

Your company's annual return date (ARD) is shown on its record on the CRO's CORE website. A new company's first ARD is six months after it was incorporated, and after that it falls on the same date each year unless the company changes it. The return must be filed within 56 days of the ARD.

Where to look

  1. Search for the company on the CRO's CORE website, core.cro.ie.
  2. Open its record. The next annual return date is shown with the company's details.
  3. Add 56 days to find the filing deadline, or use our deadline calculator.

How the date is set

  • New companies: the first ARD is six months after incorporation. See your first annual return.
  • Every year after: the ARD falls on the same date each year.
  • Changed dates: a company can extend its ARD by up to six months on Form B1B73, no more than once every five years. See changing your ARD.

The ARD isn't the deadline

The ARD is the date the return is made up to. You then have 56 days to file. Treating the ARD as the deadline gives you less time than you have; forgetting the 56 days is how companies end up late.
