## What’s New - All **Creative Industries tax relief or expenditure credit claims** submitted from **6 April 2026** must include the **new CT600P page** alongside the regular CT600 company tax return. ([gov.uk](https://www.gov.uk/government/publications/agent-update-issue-140/issue-140-of-agent-update?utm_source=openai)) - The **additional information form** supporting these claims has been updated, and must be filed **on or before** the tax return itself. This update is designed to reduce duplicates and improve clarity. ([gov.uk](https://www.gov.uk/government/publications/agent-update-issue-140/issue-140-of-agent-update?utm_source=openai)) ## Practical Examples - Imagine a film production company claiming film tax relief: alongside its CT600, it now fills out CT600P and related updated additional information form—all due at once. - A company claiming music or theatre relief must ensure their agents use updated form from HMRC guidance to avoid the claim being delayed. ## Actionable Advice for Businesses - Review your current workflows: ensure tax and finance teams are aware of CT600P changes and timeline. - Update internal checklists to include the new page/form. - Watch out for validation issues: HMRC noted a small validation bug in CT600P; it won’t affect claim validity but may require following HMRC instructions. ([gov.uk](https://www.gov.uk/government/publications/agent-update-issue-140/issue-140-of-agent-update?utm_source=openai)) ## Strategic Considerations - Count timing: prepare returns early in fiscal year to test versions of CT600P and avoid last-minute rush errors. - For businesses in UK Creative Industries, retaining external tax advisers familiar post-April 2026 process changes could protect against compliance missteps. - Ensure that accounting systems/software can generate CT600P information correctly.
