CNS Interagency Agreement (IAA) Requests

This Website is to explain the process for Federal agencies to submit an IAA to any of the programs in the NSF/CISE/CNS division, other than the IUCRC program. If your agency is submitting an IAA to the NSF IUCRC program, please visit the IUCRC IAA instruction Webpage -

Authority info

NSF has specific statutory authority that authorizes other Federal Agencies to transfer funds to NSF and NSF to use those funds to provide support to scientific and engineering research or education. NSF recommends that agencies use this provision of the NSF Act of 1950, as amended (42 USC 1861-75), as the statutory authority for the transfer of funds. All funds must be reimbursable, and the NSF Act must be the authority on which NSF accepts the funding.

IAA funds are added to existing NSF grants, as supplements or increments, or on new NSF grants. CNS grants are awarded via a competitive peer review process at NSF which eliminates the need for other federal agencies to hold a competitive procurement process. NSF cannot change the terms and conditions of the grant as a result of the IAA. Since NSF grants are not contracts, but are financial assistance awards, IAAs cannot be accepted that have acquisition or contractual requirements outlined or embedded in them, such as deliverables or reporting at intervals other than those of the original award.

In order to process your IAA request in a timely manner, you must know:

1. NSF grant number or have a completed Memorandum of Understanding (MOU) between your agency and NSF if a specific grant is not identified.

2. Full name of NSF grant Principal Investigator (PI), Institution Name, Grant Title.

3. The amount towards the effort (how much to be transferred to the NSF Awardee Institution).

4. Your agency's Agency Location Code (ALC), Treasury Account Symbol (TAS), IAA Line of Accounting (LoA), and expiration and cancelation dates for the funds.

Preparation Instructions

The following items should be sent via email, to the CNS Interagency processing team at:

The subject line should start with the words "IAA Request for "grant number" or "MOU name" followed by the Requesting Agency's agreement number. This will help expedite initial processing and facilitate follow-up.

There are two variations of IAA paperwork the CNS IAA processing team will accept. They are as follows:

    1. Completed 7600A and 7600B forms (NSF is not yet part of the G-Invoicing System - please use the November 2016 form). Please complete the highlighted areas in each form. For further 7600 Instructions please visit the U.S. Department of Treasury website.

o The following language MUST be included in block 11 of the 7600A and block 28 of the 7600B.
"Deliverables may include a report on expenditure of funds. NSF is authorized to collect an Administrative Cost Recovery (ACR) overhead rate of 7.58% (applied to the direct (programmatic) costs) for FY 2022, until further notice" Use the Administrative Cost Recovery (ACR) calculator to help compute the amount of money your agency should send to NSF. See example in Quick Tips below.

o The following language MUST be included in block 12 of the 7600A.
Statutory Authority: "This is a non-acquisition/contract/procurement agreement being entered into pursuant to the authority of the National Science Foundation Act of 1950, as amended (42 USC 1861-75). Acceptance is made with the understanding that funds will be made available pursuant to the terms and conditions of the NSF award and in accordance with the appropriation cited on the agreement."

o The following language MUST be included in block 13 and 20 of the 7600A. "Funds from the other agency will be supplemental funding to an existing or new NSF grant. NSF cannot change the terms and conditions we impose on our grantees as a result of the IAA."

    2. Completed Agency Funding document (i.e., MIPR, Economy Act Order, or agency specific IAA Form)

o The following language MUST be included in the ITEM DESCRIPTION SECTION.
Description: "NSF is authorized to deduct 7.58% (based on the total transaction) for administrative cost recovery for FY 2022, until further notice." – see example in Quick Tips below.
Statutory Authority: "This is a non-acquisition/contract/procurement agreement being entered into pursuant to the authority of the National Science Foundation Act of 1950, as amended (42 USC 1861-75). Acceptance is made with the understanding that funds will be made available pursuant to the terms and conditions of the NSF award and in accordance with the appropriation cited on the agreement."

o If the IAA does not contain the requesting agency's Agency Location Code (ALC), Treasury Account Symbol (TAS), Line of Accounting, and the funding expiration and cancelation dates, the requesting agency must complete the NSF 1611 form (highlighted areas).


When funds from an IAA are applied to an NSF grant, billing must be cost reimbursable, and payment will be done via IPAC (Intra-Governmental Payment and Collection System) notification.

Occasionally, an obligated IAA may not have been billed and invoiced by the grantee's institution and thus NSF is unable to bill the funding agency. The grantee's institution is responsible to ensure that the following steps have taken place:

1. Requesting agency: Notifies both NSF ( and the University that there is an outstanding amount against the IAA,

2. University: Informs NSF's Cash Management Section that the amounts under the IAA have been expended; and,

3. NSF's Accounting Operations Branch: Receives report from the Cash Management section and submits an invoice to the requesting agency, for questions please email DFM IPAC-IA (

Submission Deadline Notice

To ensure obligation of funds prior to the end of the fiscal year, IAAs must be submitted to the NSF CNS division no later than the end of June of the corresponding Fiscal Year. All submissions sent after that date will be returned to the submitting agency if funds are due to expire at the end of the Fiscal Year. Submissions sent after the deadline can be held over until the new fiscal year if the funds are not due to expire until the end of the new fiscal year or later.


  • 15 to 30 days - to process an agency IAA request once NSF receives a complete and accurate IAA package as outlined in the Preparation Instructions above.
  • 10 to 30 days after the IAA documents are processed - to process the NSF grant.
  • Additional Information

    If you have any questions about the CNS Interagency Agreement process, please contact the CNS IAA Processing Team at

    Quick Tips

      The IAA process starts.

      The requesting agency should either reach out to the NSF grantee PI (not NSF) to discuss possible funding or to an NSF/CISE/CNS Program Officer (PO) if a specific NSF grant has not been identified.

      The parties involved in the IAA process.

      The process begins with the scientist from the requesting agency having a conversation with the NSF grantee (PI) or NSF cognizant program officer (PO). The NSF PO will refer the requesting agency's POC to the NSF grantee. The NSF Grantee PI should negotiate the terms of the IAA agreement with the requesting agency, including the total amount of the IAA and the amount to be transferred to the grantee.

      The different kinds of IAA forms, and why are they different.

      NSF does not dictate which IAA form must be used. Military agencies usually use either a MIPR or Treasury Form 7600 A&B. NSA uses the Economy Act Order. NASA, DHS, USGS, and other agencies use their own IAA form. NSF is not yet part of the Federal G-Invoicing System, so at this time, cannot accept IAAs via that system.

      A normal IAA timeframe.

      The negotiation process to make sure the IAA form is acceptable to NSF can take from days to weeks. Once the form is acceptable to NSF and completely signed by the Requesting Agency, the process takes 2-3 weeks for acceptance.

      The information needed to start an IAA.

      If an existing NSF grant is to be supplemented, the following info must be on the IAA:

      NSF Grant Number,

      NSF Grantee (PI) name,

      NSF Grantee Institution Name,

      NSF Grant Title,

      plus, the below Funding Agency Accounting Codes.

      If a designated NSF grant is not identified - NSF and the sending agency must first negotiate a Memorandum of Understanding (MOU) which will identify the NSF effort to be funded, approximate amount to be sent to fund that effort, and duration of the effort.

      Funding Agency Accounting codes needed on an IAA.

      Agency Treasury Account Symbol (TAS) - An identification code assigned by the Department of the Treasury, in collaboration with the Office of Management and Budget and the owner agency,

      to an individual appropriation, receipt, or other fund account. (These accounts are defined in TFM Volume I, Part 2, Chapter 1500.)

      Agency Location Code (ALC) - Identifies the accounting office within an agency that reports disbursements and collections to the Department of the Treasury.

      Interagency Agreement Number - assigned by the funding agency

      Agency Line of Accounting

      Funds Type (year of money - one-year, two-year, no-year, etc.)

      Fund Cancelation Date

      Fund Expiration Date

      Funds must be reimbursable not direct cite (advanced)

      The Administrative Cost Recovery (ACR) and how is it calculated.

      The anti-deficiency Act requires NSF to recover the administrative costs associated with the work performed processing the IAA. This amount is known as the Administrative Cost Recovery or ACR. The ACR overhead rate for Fiscal Year 2022 is set at 7.58%, which will remain in effect until canceled.

      NSF will calculate the ACR by multiplying the overhead rate against the direct (programmatic) costs for all “incoming” IAAs as illustrated below.

      ACR Overhead Fee Calculation Example:

      Direct (programmatic) costs of $100,000 x 7.58% overhead rate = $7,580

      Total IAA amount of $107,580 = $100,000 direct costs + $7,580 overhead fee

      ACR Overhead Fee calculator

      Transfer funding authority to use.

      Funds must be accepted by NSF using the statutory authority - NSF Act of 1950 as amended (42 USC 1861-75).

      The NSF signing official on IAAs.

      An Authorized Official for the cognizant servicing program office to sign the IAA must be delegated, in writing, by the Division Director or the Deputy Assistant Directorate for the Directorate to an NSF employee who has the appropriate knowledge to attest to starting work and accounting for use of the funds being transferred to NSF.

      Any special language required by the NSF program to be funded should be on the IAAs. This information can be confirmed by the grantee and NSF staff.

      Program restrictions that might affect the IAAs.

      Funding agency POCs must confirm with NSF programmatic POCs whether there are any restrictions that might affect the language and terms of the IAA.

      When a Memorandum of Understanding (MOU) is needed.

      If a specific valid NSF grant is NOT identified by the funding document, a MOU is required. The MOU must be completed before a funding document can be accepted.
