Ireland R&D Tax Credits - new 90-day "Pre-Filing" notification

Summary of this Update & Impact

New R&D tax credit claimants (or those who haven't claimed in 3 years) in the Republic of Ireland, will need to notify Revenue with one or two forms (766C and 766D), 90 days before they file their claim. 

This will mean that these claimants will have to get a handle and focus on their R&D tax credit claim, 90 days earlier than in previous years. 

Example of Deadlines:

  • Financial Year End December > Pre-Filing Notification June > Corporation Tax Deadline September

Note - this is not tax advice, and any tax details should be discussed with your tax agent.
