The main purpose of this legislation, known as the Fiscal Sponsorship Transparency Act of 2026, is to enhance transparency and accountability among charitable organizations that engage in fiscal sponsorship arrangements. These arrangements allow one organization to manage funds on behalf of another, often for specific projects. The law aims to ensure that these organizations report detailed information about such arrangements to prevent misuse of funds and to clarify the responsibilities involved. Key provisions of the law include new reporting requirements for charitable organizations.
