Indirect Cost Services (ICS) negotiates and issues indirect cost rates on behalf of the Federal Government. Our rate negotiation process begins with an organization‘s submission of an indirect cost rate proposal (ICP) with supporting documentation including the organization‘s audited financial statements. Our services help ensure that indirect costs paid by the federal government are legally sound, fair, and equitable.

ICS negotiates with organizations that receive the majority of their federal funding from the Department of the Interior or are designated by OMB to negotiate with DOI, i.e. insular areas and tribal governments. Additionally, ICS negotiates with various nonprofit organizations on behalf of other federal agencies or departments through interagency agreements.

Preparing and Submitting an Indirect Cost Proposal

Guidance for preparing your indirect cost proposals (ICP) or cost allocation plan (CAP) proposals differs depending on the organization type submitting the proposal. For the appropriate guidance and tools please select your organization type:
  • Non Profit
  • Indian Tribal Governments
  • Insular Areas, State & Local Governments

ICP Submission Timeframes

The ICP or CAP is due in within 6 months after the close of each fiscal year. For example, your indirect cost proposal is due annually, on or before:
  • March 31st if your fiscal ends on September 30th
  • June 30th if your fiscal year ends on December 31st
  • December 31st if your fiscal year ends on June 30th

Please be advised that we do not solicit proposals. Proposals are processed on a first-in first-out basis.
