This legislation aims to extend the operational period of the National Flood Insurance Program (NFIP) by reauthorizing its financing mechanisms and overall program expiration. It specifically amends existing law to change the program's end date from September 30, 2023, to December 31, 2026 , ensuring the continued availability of flood insurance. This extension is critical for policyholders and communities relying on the NFIP. The bill achieves this by modifying sections 1309(a) and 1319 of the National Flood Insurance Act of 1968. A key provision establishes a retroactive effective date : if the Act is enacted after September 30, 2025, the amendments will take effect as if they were enacted on September 30, 2025, preventing any lapse in coverage or authority.
