Other Transaction Authority gives certain federal agencies the flexibility to use a special award mechanism. Some agencies with the authority to use OTAs are NASA, the Department of Defense (DoD), Department of Health and Human Services (including NIH), and Department of Energy (DOE).
OTAs are not grants, cooperative agreements, or contracts. When we receive an OTA we must pay close attention to the terms and conditions in the agreement as they likely differ from what we are used to seeing in federal grants and contracts.
Other Transaction Authority is a project type on the eGC1 in SAGE.
