A surplus lines broker is a specially licensed insurance broker authorized to place coverage with non-admitted insurers when carriers in the standard admitted market decline a risk. Before making the placement, the broker must usually document a diligent search of the admitted market, and afterward the broker remits the surplus lines premium tax to the state.
You will meet this term when your business gets quoted through the excess and surplus lines market: a new venture, a tough claims history, or a class of business admitted carriers will not touch. The quote arrives through a wholesaler, and the paperwork suddenly includes tax line items your standard policies never had.
Surplus Lines Broker
A broker holding a surplus lines license who negotiates coverage on behalf of a client with non-admitted insurers, documents the required diligent search, remits the surplus lines premium tax, and files each placement with the state.
What does a surplus lines broker actually do?
The broker's job is access. Non-admitted insurers are not licensed in your state, so an ordinary agent cannot bind coverage with them. A surplus lines broker can, and that is the whole point of the license. Most retail agents do not hold one. They send declined risks to a wholesale surplus lines insurance broker who shops the E&S market on their behalf.
The trade is real coverage for reduced protection. Non-admitted carriers do not participate in state guaranty funds, and their rates and forms are not filed with regulators. E&S carriers often use manuscript policy forms with provisions that differ from standard filed forms, which is why you should read an E&S quote line by line rather than assume it mirrors the admitted policy it replaces. The difference between admitted and non-admitted carriers drives everything else on this page.
What is the diligent search requirement?
Before placing your risk with a non-admitted insurer, the broker must confirm the admitted market genuinely rejected it. In most states that means documenting declinations from around three admitted carriers actually writing that class of business. In California the broker files a diligent search declaration, the SL-2, and a certificate reviewer at the stamping office will bounce a filing whose declinations name carriers that do not even write the class.
Two paths skip the search. If the coverage sits on the state's export list of risks the admitted market is known to avoid, no declinations are needed. Large buyers who qualify as exempt commercial purchasers can also waive the search in writing.
Who pays the surplus lines tax?
You do, through the broker. Admitted carriers pay state premium taxes themselves, but a non-admitted insurer has no license to tax, so the state collects from the broker instead. The surplus lines broker calculates the tax, shows it on your invoice, and remits it.
In California that is a 3.0% surplus lines premium tax plus a 0.18% stamping fee paid to the Surplus Line Association, which reviews every filing. Rates vary by state, listed in our surplus lines tax rates by state guide, and since the federal NRRA took effect in 2011, only your home state taxes the placement and only your home state's surplus lines license matters. A California broker needs active Property and Casualty Broker-Agent licenses plus a $50,000 bond under Insurance Code section 1765(c). Marine, aviation, and railroad risks follow a separate California license, the special lines' surplus line broker, with its own rules.
Frequently asked questions
Is a surplus lines broker the same as a wholesale broker?
Usually in practice, not by definition. The surplus lines license is what authorizes non-admitted placements. Most holders work at wholesale brokerages that retail agents send business to, but a retail broker can hold the license directly and place E&S business without a wholesaler.
Is surplus lines insurance safe to buy?
It can be. Non-admitted carriers skip rate and form filing but still face eligibility and capital requirements, and many are large, highly rated insurers. The real loss is guaranty fund protection: if the carrier fails, no state fund steps in to pay your claim.
Why is my surplus lines policy taxed separately?
Because the insurer is not licensed in your state and pays no premium tax there. The state collects through the broker instead, so the tax and any stamping fee appear as line items on your invoice rather than being baked into the rate.
Do I need declinations for every surplus lines placement?
No. Coverage on your state's export list needs no diligent search, and exempt commercial purchasers can waive it in writing. Everything else typically requires documented declinations from admitted carriers, roughly three in most states. Your broker handles the filing.
