The Mechanism is funded from the UN regular budget and operates on an annual budget approved by the General Assembly. This budget ensures that the Mechanism has the necessary resources, personnel and expertise to carry out its complex mandate.

The Mechanism also seeks voluntary contributions from donors and other entities for discrete projects and highly specialized expertise. The Mechanism is grateful to Australia, Austria, Canada, Denmark, Malta, Switzerland, the United Kingdom, the United States, Justice Rapid Response and others for the voluntary contributions they have made to the Mechanism to enhance its investigative capacities and outreach activities.
