TIBC Suggested Survey Responses


The mission of the Tribal Interior Budget Council (TIBC) is to provide an advisory government-to-government forum and process for Tribes and the U.S. Department of the Interior (DOI) to develop budgets that allow for the fulfillment of Tribes' self-determination, self-governance, sovereignty, and treaty rights, as well as sufficient levels of funding to address the needs of Tribes and their tribal citizens.

NOTICE: The TIBC cooperative agreement between the DOI and NCAI expired on January 1, 2026. DOI will lead all TIBC meeting coordination and planning in-house. NCAI will continue to update Tribal Leaders on TIBC developments, but Meeting Materials for future meetings will not be available through NCAI. Meeting Materials for previous meetings held in accordance with the previous cooperative agreement will be maintained for archival purposes.

Update: Written Comments and Focused TIBC Session

In March, the DOI issued a Dear Tribal Leader Letter (DTLL) inviting Tribal Nations to submit written comments by April 17, 2026, and participate in a focused TIBC session in Washington, D.C., on May 19-20, 2026, where discussions will center on the FY2028 budget process and the future structure of TIBC itself.

In preparation, NCAI is convening a webinar on Monday, March 13, 2026, at 2:00 p.m. ET, to ensure Tribal Leaders are fully informed and prepared to engage in the next chapter of TIBC. Please join NCAI as we walk through the DOI letter, provide resources and talking points to help Tribal Leaders craft meaningful comment letters, and outline upcoming engagement opportunities to ensure your Nation's priorities are heard.
