Marine Invasive Species Fee Guide
The Marine Invasive Species Fee is jointly administered by the State Lands Commission and the California Department of Tax and Fee Administration (CDTFA).
The Marine Invasive Species Fee you pay to the state provides funding to combat the introduction and spread of non-indigenous aquatic species into California waters.
We developed this guide to provide you with easily accessible information to assist you in understanding the Marine Invasive Species Fee Program and the obligations of vessel owners and operators, and marine agents.
Marine Invasive Species Fee
The marine invasive species fee was established in 1999 to address the introduction and spread of foreign aquatic species into California waters. (Public Resource Code 71200 et seq.)
The fee rate is set by the State Lands Commission. The California Department of Tax and Fee Administration (CDTFA) is responsible for the collection of the fee. The CDTFA works with the California Marine Exchanges (CME) to identify daily arrivals of vessels into California ports.
How the Revenue is Used
The funds are used to support the marine invasive species program established to prevent the introduction and spread of foreign non-indigenous aquatic species into the state waters of California. (PRC 71200 et seq.)
