This legislation, titled the NFIP Extension Act of 2026 , aims to reauthorize the National Flood Insurance Program (NFIP) by amending the National Flood Insurance Act of 1968. Its primary purpose is to ensure the continued operation and financing of the federal flood insurance program. Specifically, the bill extends the program's financing authority and its overall expiration date. It changes the current expiration from September 30, 2023 , to September 30, 2026 , providing a three-year extension. Furthermore, the bill includes a crucial provision for a retroactive effective date , ensuring that if enacted after September 30, 2025, the extensions will still apply as if they took effect on that date.
