Ireland’s research and development (R&D) tax credit scheme has been a valuable mechanism for companies to reduce the cost of their R&D activities, encouraging more investment and resource input into the teams that perform this important IP-generating aspect of our economy. The scheme has been continually improved since it was introduced in 2004, Until recent years it has not been subject to major changes, with just a few tweaks and adjustments. Since 2022, however, more significant updates have been made. These are not impacting the type of development work that qualifies as R&D nor the expenditure in doing that work that can be claimed. The changes relate to how the credit is claimed and received.
