Surplus Lines Tax

Industry

Definition

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.

Surplus Lines Broker
A specially licensed insurance broker authorized to place insurance with non-admitted (surplus lines) carriers. Surplus lines brokers must hold a surplus lines license in addition to a standard insurance broker license. Before placing coverage in the surplus lines market, the broker is required to conduct a diligent search to demonstrate that coverage is not available from admitted carriers in the standard market. The surplus lines broker is responsible for ensuring the surplus lines insurer meets state eligibility criteria, collecting and remitting surplus lines premium taxes to the state, and providing required filings and documentation. They serve as the critical link between clients with hard-to-place risks and the non-admitted insurance market.
Excess and Surplus Lines
The non-admitted insurance market for risks that cannot be placed in the standard admitted market due to unique characteristics, high risk, or lack of available coverage. Excess and surplus lines insurers are not licensed (admitted) in the state where the risk is located, which provides them flexibility in rates and policy forms not subject to state prior approval requirements. However, they must meet financial requirements and are listed on state-approved eligible surplus lines insurer lists. The E&S market serves as a critical safety valve for the insurance system, providing coverage for unique, high-risk, or emerging exposures. Common E&S placements include high-value properties, unusual liability risks, and specialized commercial coverages. The U.S. surplus lines market exceeded $131 billion in direct premiums written in 2024, representing approximately 12% of the total property and casualty market.
Stamping Office
An organization that collects surplus lines premium taxes, fees, and required filings on behalf of surplus lines brokers and forwards them to state regulatory authorities. Stamping offices serve as clearinghouses that simplify the administrative burden of multi-state surplus lines placements by providing a centralized point for tax collection and regulatory compliance. They verify that surplus lines insurers are eligible to write business in the applicable states, validate diligent search documentation, and ensure proper tax calculation and remittance. The Surplus Line Taxes and Fees Multi-State Compliance Compact (SLTC) is a prominent example of a stamping office that facilitates compliance across multiple jurisdictions.
Non-Admitted Insurance
Insurance placed with carriers not licensed (admitted) in the state where the insured risk is located. Non-admitted insurers, also called surplus lines insurers, are not subject to state rate and form approval requirements, giving them flexibility to underwrite unique or high-risk exposures. However, they must meet financial requirements and be listed on the state's approved eligible surplus lines insurer list. Non-admitted policies are not protected by state guaranty funds in the event of insurer insolvency, though historical insolvency rates for surplus lines carriers are low. Non-admitted insurance can only be placed after a surplus lines broker conducts a diligent search in the admitted market and documents that coverage is not available from admitted carriers.
Actuary
A business professional who analyzes probabilities of risk and risk management, including calculation of premiums, dividends, and other applicable insurance industry standards.
Underwriting
The process by which an insurer evaluates the risk of insuring a person or property and determines coverage terms and premium rates.
Loss Ratio
The ratio of losses paid plus loss reserves to premiums earned, used by insurers to measure underwriting profitability and pricing adequacy.
Combined Ratio
The sum of the loss ratio and expense ratio, measuring an insurer's overall underwriting profitability. A ratio below 100% indicates underwriting profit.
