No-cost extension

Before you attempt to extend your project, please review the following information. Please note that you (as an awardee) can’t grant yourself a no-cost extension.

Phase I awardees

Applying for a no-cost extension could impact the possible deadline dates for your Phase II proposal. Please get in touch with your program director to learn more about how a no-cost extension could impact your deadline dates.

Requirements for a no-cost extension

Here are the requirements for a no-cost extension, excerpted from the NSF’s Grant Proposal Guide:

  • You must submit your request to NSF at least 45 days prior to your award’s expiration date. Your request must explain why you need the extension and include an estimate of the unobligated funds remaining and a plan for how you’ll use them. Having unobligated funds when your award expires isn’t in itself a sufficient justification for an extension.
  • Your plan must follow the previously approved objectives of the project. Any NSF-approved no-cost extension will be issued by an NSF Grants Officer in the form of an amendment to your award and will specify a new expiration date. Please do not make new commitments or incur new expenses after your award’s expiration date in anticipation of a no-cost extension.
