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.

NSF's Indirect Cost Rate Policies

This page outlines important information regarding the U.S. National Science Foundation's indirect cost rate policies.

What are indirect costs?

Indirect costs are those costs which are not readily identifiable with a particular cost objective (e.g., direct organizational activity or project), but nevertheless are necessary for the general operation of an organization.

Examples of indirect costs include the salary and related expenses of individuals working in accounting, personnel, purchasing functions, rent, depreciation and utilities.

Organizations generally charge indirect costs to federal awards by developing and applying an indirect cost rate, which is used consistently across an organization's awards.

In order to recover indirect costs related to federal awards, most organizations must negotiate an indirect cost rate with the federal agency that provides the preponderance of funding to that organization — in the case of colleges and universities, this is usually the Department of Health and Human Services or the Office of Naval Research.

Indirect cost recovery on NSF awards

Because indirect cost recovery can be limited on NSF awards and could require post-award adjustments, awardees should ensure they understand the limitations relating to indirect cost recovery. These limitations will be specified in the NSF award letter or the negotiated indirect cost rate agreement, or NICRA. These limitations include:

  • Type of rate.
  • Percentage rate.
  • Application base.

Type of rate

Important indirect cost rate categories are detailed below. Note: Due to limitations of funds provided under assistance awards, grants and cooperative agreements, additional funds will not be provided to cover increases in indirect costs, regardless of the type of rate used.


Application base

The federal government in general, and NSF specifically, does not permit indirect costs to be recovered on certain types of costs. Commonly excluded costs include:

  • Equipment and capital expenditures.
  • The portion of subawards that exceed $50,000 (per subaward, regardless of period).
  • Participant support costs.

Awardees must have a detailed understanding of the terms and conditions related to the indirect cost rate or award specific rates to correctly calculate indirect cost recovery charges and any potential post-award adjustments.

Information for organizations without negotiated indirect cost rate agreements

Organizations without negotiated indirect cost rate agreements can either use a de minimis indirect cost rate or can submit an indirect cost rate proposal.

De minimis rate approach

For awardees that have never received a negotiated indirect cost rate agreement or do not hold a current NICRA, 2 CFR 200.414(f) allows the use of an indirect cost rate of 15% of the project's modified total direct costs (MTDC). Pass-through organizations may also apply this rate.

If this de minimis approach is chosen, the 15% rate must be applied consistently across all an organization's federal awards until the organization chooses to negotiate an indirect cost rate.


Indirect cost rate proposal

NSF negotiates formal negotiated indirect cost rate agreements, or NICRAs, for ~100 organizations. These organizations are required to regularly (typically annually) submit proposals to update their indirect cost rates. NSF does not negotiate indirect cost rates for organizations that are not direct recipients of NSF funding — such as subrecipients — or for foreign organizations.

NSF's Cost Analysis and Pre-Award Branch is responsible for negotiating and issuing indirect cost rates for NSF's cognizant awardees. Based on various information available (e.g., historical cost information and the level of funding being requested), the branch negotiates the funding of indirect costs, typically as a rate.

In rare circumstances, NSF may decline to negotiate an indirect cost rate and instead recommend an award­-specific amount.
