“Can I submit a renewal application after my current project period has ended?”

Yes, NIH does not set a time limit for a renewal application relative to the previous project period.

Our advice, however, is that you apply for a renewal before your project period ends to avoid a gap in funding, which better ensures the continuity of your research. For a significant break between your project period ending and submitting a renewal application, you’ll need to explain the hiatus and demonstrate how your planned research remains at the cutting edge of your field.
