A tax imposed by states on surplus lines (non-admitted) insurance premiums, typically ranging from 2% to 6% of the premium amount. The surplus lines tax is collected by the surplus lines broker at the time of policy placement and remitted to the state where the insured risk is located (the 'home state' under the Nonadmitted and Reinsurance Reform Act). This tax serves as a substitute for the premium taxes that admitted insurers pay. The broker is responsible for calculating, collecting, and remitting the tax, along with required filings documenting the placement. Stamping offices often facilitate the collection and distribution of surplus lines taxes across multiple states.
