HMRC has initiated a widespread letter campaign addressing potential inconsistencies in benefit claims and the high-income child benefit charge within clients’ self-assessment returns for the fiscal year 2021-22. The correspondence outlines HMRC’s intention to reach out to agents, furnishing them with additional information. The goal is to empower agents to assist their clients in rectifying any inaccuracies proactively, thereby avoiding the necessity for a formal inquiry. A duplicate of the letter can be accessed on the CIOT website.
