This bill aims to provide stable and predictable funding for crucial programs serving Native American communities by authorizing advance appropriations for key accounts. It specifically targets the Bureau of Indian Affairs (BIA) and the Bureau of Indian Education (BIE) within the Department of the Interior, as well as the Indian Health Service (IHS) under the Department of Health and Human Services. By amending the Indian Self-Determination Act and the Indian Health Care Improvement Act , the legislation seeks to improve financial planning and service delivery for tribal governments. Beginning with fiscal year 2026, the bill mandates that new budget authority for designated accounts will include advance appropriations for the subsequent fiscal year. For the BIA, covered accounts include Operation of Indian Programs, Contract Support Costs, and Construction, among others. The BIE's covered accounts include Operation of Indian Education Programs and Education Construction, while the IHS's include Indian Health Services, Contract Support Costs, and Indian Health Facilities. Furthermore, the legislation requires the Secretaries of the Interior and Health and Human Services to submit detailed estimates for these covered accounts for the fiscal year following the budget year as part of the President's annual budget. Both Secretaries must also consult with Indian Tribes and submit annual reports by July 31st on the sufficiency of resources, including workload and demand data, for the upcoming fiscal year. These provisions are designed to enhance transparency, accountability, and tribal participation in the budgeting process.
