Currently a submission for Creative Tax credits cannot be made. An future update will be made in the next release to allow for creative tax credit submission for April 2025.
HMRC required the completion of new ‘Creative Industries CT600P‘ supplementary page from April 2025 in respect of any claims to Creative reliefs and tax credits including Audio-visual and Video Games expenditure credits(AVEC).
IRIS has incorporated this requirement into IRIS version 25.1. However, due to issues with HMRC online filing service it is not possible to submit a return containing a claim to creative reliefs and tax credits. In light of the issues with the HMRC online service HMRC made a last-minute decision to postpone the implementation of the new supplementary page until April 2026. Unfortunately, this decision was not received with sufficient time for the IRIS software to be updated ahead of the release in April 2025. When attempting to generate an internet return a warning message will appear below:.
Selecting Yes on this window and proceeding to submit the return a validation error will be received from HMRC: You can either await development from HMRC (Details are still to be TBC) or print and submit by paper.
