# §1000.890. How are indirect cost rates determined?


The Department's Interior Business Center (IBC) or other cognizant Federal agency and the Tribe/Consortium negotiate indirect cost rates. These rates are based on the applicable provisions of [subpart E](/cfr/25/subpartE.md) of [2 CFR part 200](/cfr/2/part200.md), or other applicable OMB cost circular and the provisions of title I of the Act, as amended. These rates are used generally by all Federal agencies for contracts and grants with the Tribe/Consortium, including self-governance agreements.
