Implementation of standard 15% indirect cost rate

NSF is updating its policy regarding the reimbursement of indirect costs in federally funded financial assistance.

Read the policy.

Important information regarding OMB's Supplementary Information for Federal Agency Implementation of 2 CFR 200 (August 15, 2024)

Negotiated Indirect Cost Rate Agreements (NICRAs) negotiated prior to October 1, 2024 must continue to be honored by both federal agencies and recipients. However, cognizant agencies for indirect costs may — but are not required to — renegotiate existing NICRAs (i.e., issue revised or amended agreements) to reflect the new MTDC base. NSF will consider requests to modify existing rate agreements on a limited case-by-case basis. Requests for revisions should be emailed to bfacapidc@nsf.gov.

  • Provisional rates: Recipients with provisional rates in effect prior to October 1, 2024 must finalize those rates using the provisional rate's approved MTDC base. Future provisional rates must be negotiated with the new MTDC base on or after October 1, 2024.
  • Predetermined and fixed rates: Recipients with predetermined or fixed rates must use the new MTDC base beginning with the first rate proposal that is required on or after October 1, 2024.
  • Negotiating new rates: Recipients preparing indirect cost rate proposals must apply the new MTDC base for rate proposals that are submitted to the cognizant agency for indirect costs on or after October 1, 2024.

De minimis rates 

  • New awards: Unless otherwise noted in a program solicitation, recipients may elect to use the new 15% de minimis indirect cost rate for any award executed on or after October 1, 2024.
  • Existing awards: Unless otherwise noted by the program solicitation/award letter, awardees may apply the 15% de minimis rate to existing awards, provided that there are sufficient funds to do so and still adequately meet stated project objectives. The 15% de minimis rate may only be charged to costs incurred after October 1, 2024; recipients may not retroactively apply the de minimis rate to costs incurred prior to this date.

Indirect Cost Rate Proposal Submission Procedures

This webpage outlines the procedures for submitting a formal indirect cost rate proposal to the U.S. National Science Foundation (NSF) for the purpose of establishing a formally negotiated indirect cost rate agreement (NICRA).

NSF only negotiates indirect cost rates with those domestic entities who receive the preponderance of their direct funding from the agency.

Organizations who function solely as subrecipients (and who do not receive their funding direct from NSF) should negotiate an indirect cost rate with the prime awardee, in accordance with 2 CFR 200.332.

Foreign organizations that do not have a current U.S. federally negotiated indirect cost rate(s) are limited to a de minimis indirect cost rate recovery of 15% of modified total direct costs, unless they have negotiated a formal indirect cost rate agreement with another federal agency.

Awardees that are new to NSF

Potential NSF SBIR Phase II awardees who do not hold a current NICRA with a federal agency and who wish to request indirect costs in excess of the SBIR "safe rate" may submit an indirect cost rate proposal as part of the documentation provided for the Phase II Administrative/Financial Reviews.

If your SBIR/STTR organization has been directed to provide the documentation needed by NSF to conduct administrative and financial reviews, the rate proposal should be sent in electronic format within 10 calendar days of the date of the request to bfacapsbir@nsf.gov.

Please note that submitting a rate proposal for the purpose of NSF SBIR/STTR Phase II funding will not result in the issuance of a formal NICRA but will establish a rate that the SBIR/STTR awardee may use for their NSF Phase II award only.

Potential NSF awardees who do not hold a current NICRA with a federal agency should generally budget indirect costs at the 15% de minimis rate (as authorized by 2 CFR 200.414(f)) unless otherwise authorized by the program solicitation and/or instructed to do by the cognizant NSF grants and agreements officer.

Existing NSF awardees who do not hold a NICRA

Existing NSF awardees who do not hold a current NICRA with a federal agency may choose to negotiate a formal rate agreement with NSF, provided that NSF provides the preponderance of their direct funding and is therefore their cognizant agency for indirect costs.

To begin a rate negotiation, the awardee should prepare the calculations and compile the documentation as detailed in these indirect cost rate proposal submission procedures.

Please note that once a formal NICRA is in effect, an awardee is no longer eligible to apply the de minimis rate while the NICRA remains current.

Awardees that negotiate a NICRA with NSF as the cognizant agency for indirect costs

Organizations that have previously established a NICRA with NSF must submit a new rate proposal to the NSF Cost Analysis and Pre-Award Branch within six months after the close of the organization's fiscal year.

Awardees that have not previously negotiated an ICR with NSF must submit their proposals no later than three months after the effective date of an award.

Proposals should be submitted electronically to bfacapidc@nsf.gov.

Federal requirements

NSF reviews indirect cost proposals for a diverse population of awardees. Each organization must comply with the applicable federal requirements contained in 2 CFR 200: Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards related to:

Specific indirect cost requirements are applicable to different types of organizations, as follows:

Are required to follow the cost principles contained in:

Audit requirements are the responsibility of the cognizant federal agency.

Are required to follow regulations contained in 2 CFR 200, "Appendix VII—States and Local Government and Indian Tribe Indirect Cost Proposals."

Note: Because the federal organization providing the preponderance of funding is normally the cognizant agency, NSF is rarely the cognizant agency for state and local government agencies.

Are required to follow the regulations contained in 2 CFR 200, "Appendix III—Indirect (F&A) Costs Identification and Assignment, and Rate Determination for Institutions of Higher Education."

Note: NSF does not negotiate indirect cost rates with institutions of higher education. 2 CFR §200, Appendix III(c)(11) assigns cost negotiation cognizance for educational institutions primarily to the Department of Health and Human Services (HHS) or the Department of Defense's Office of Naval Research (ONR). NSF recommends that these institutions prepare an indirect cost proposal in accordance with the guidance on the HHS/ONR websites and use the rate calculated from that guidance in proposals submitted to NSF. If NSF subsequently issues an award, the institution should then go to HHS/ONR to complete a rate negotiation. For more information, visit the HHS website or the ONR website.
