The Irish Revenue has released eBrief No. 303/24, providing updated guidance on anti-hybrid rules on 10 December 2024.

The purpose of anti-hybrid rules is to prevent arrangements that exploit the differences in the tax treatment of an instrument or entity arising from the way in which that instrument or entity is characterised under the tax laws of two or more territories to generate a tax advantage or a mismatch outcome.
