Private equity firms are facing increased scrutiny from HMRC as they expand their influence in the professional services sector. A significant development in the tax world, this huge story comes as private equity groups are poised to own one in three top US accounting firms. This move has raised concerns, especially given their recent opposition to SEC efforts to increase transparency in their operations. Additionally, these firms are targeting middle-market fintech and payment companies, as reported by Digital Finance News, indicating a broader strategy to diversify their investments.
