Every insurance company you buy from is either admitted or not in the state where the risk sits. Admitted means the state licensed the company, its rates and policy forms are subject to review by the state insurance department, and its policyholders have the state guaranty fund behind them if the company fails. Surplus lines, also called nonadmitted, means the company is not licensed in that state but is eligible to write there through a surplus lines broker, usually after the admitted market has turned the risk down. It uses its own forms and its own pricing, and the guaranty fund does not stand behind it. Neither is better. One is the standard market with more rules and a safety net; the other is where unusual, new or high-hazard risks get placed when the standard market says no.
What admitted means
The federal Nonadmitted and Reinsurance Reform Act defines an admitted insurer as one licensed to engage in the business of insurance in a state, and a nonadmitted insurer as one that is not. An admitted carrier’s rates and policy forms are subject to review by the state insurance department; Washington’s insurance commissioner says its office is not allowed to review surplus line companies’ rates and policies, and Texas’s Office of Public Insurance Counsel says surplus lines insurers do not have to let the state review theirs.
The second thing admitted carriers bring is the guaranty fund. NAIC describes it as a protection funded by admitted insurers that pays claims if an admitted insurer becomes insolvent. If your admitted carrier fails mid-claim, that fund is designed to step in.
What surplus lines means
A surplus lines carrier is not licensed in the state where the risk is, but it is eligible to write there. NAIC puts it this way: it is the surplus lines transaction that is regulated, and the surplus lines broker is responsible for making sure the insurer meets the state’s eligibility criteria.
California requires a signed disclosure when you apply, in 16-point boldface on its own page and on the front of the policy, stating that the insurer is not licensed by the state, is not subject to the financial solvency regulation that applies to California licensed insurers, and does not participate in any California insurance guarantee fund. Texas requires a notice on the policy that the insurer is not licensed in Texas and that the policy is a surplus lines policy. NAIC also notes that the insolvency rate of surplus lines insurers is historically low, so I treat the guaranty fund gap as a tradeoff to weigh, not a reason to refuse the market.
Diligent search, export lists and the home state rule
- Diligent search. Before a broker goes nonadmitted, the state wants proof the admitted market was tried. In California, three declinations from admitted insurers that actually write that type of insurance count as evidence of a diligent search, documented on a standardized form filed with a confidential written report within 60 days of the placement. New York requires a diligent effort among authorized insurers first and sets the number of declinations that constitute it at three.
- Export lists. Some states publish a list of coverages that can go straight to surplus lines without a search. California’s 2025 Export List, issued November 24, 2025, added Commercial Cannabis Related Operations and includes vacant buildings, excess motor truck cargo and several high-hazard contractor classes. California renews it after a public hearing at least yearly; New York lets its superintendent set a different declination count for particular coverages, also reviewed yearly.
- Large buyers. The NRRA lets an exempt commercial purchaser skip the search when the broker discloses that admitted coverage may or may not be available and the buyer then asks in writing for a nonadmitted placement. California has a parallel rule for commercial insureds.
- One state’s rules. Since the NRRA took effect in July 2011, a surplus lines placement answers only to the insured’s home state: the principal place of business (for an individual, principal residence), or, if the whole risk sits outside that state, the state with the largest share of the premium. Only that state can require the surplus lines premium tax.
Taxes, fees and what the policy looks like
A surplus lines policy carries a premium tax that the broker remits to the home state. Some states also run a stamping office that charges a stamping fee on the broker’s filings. Texas’s stamping office describes its fee as an assessment on each surplus lines policy issued through a broker, collected when the policy is filed; it is charged on every filing submitted to the office at a rate the Texas insurance commissioner sets by order under Texas Insurance Code §981.154. Ask to see premium, tax and fee as separate invoice lines. The policy is the carrier’s own form, not a state-reviewed one, so I read the exclusions with you line by line. That freedom to shape coverage and pricing is why the market exists.
When surplus lines is the right or only market
Where it comes up in my work:
- Wildfire-exposed homes. When no admitted insurer will write a home in a brush area, the file goes through the same diligent search. High-value homes in brush areas are the usual case I see; Washington’s own examples include a home on the side of a steep bank and an extremely old home.
- New trucking authorities. NAIC notes that the new products this market writes typically have no loss history and are hard to price with common actuarial methods. A trucking company in its first year of authority has no loss history of its own either, which is why so many first quotes I see are nonadmitted. Ask who makes the federal filings before you bind: what the MCS-90 endorsement is.
- Cannabis. California added Commercial Cannabis Related Operations to its export list in 2025 after a public hearing and a finding of no reasonable or adequate admitted market, or a product too new for one to have developed.
- High-hazard contractors. Blasting, demolition, crane and rigging, scaffold and new tract-home builders are on California’s export list, and in my experience the same contractor classes are hard to place in other states too.
Not better, just different: reviewed forms and a safety net on one side, a market built for declined risks on the other. The rules differ state to state; see the by-state pages.
Common questions
Is a surplus lines carrier an unlicensed or unsafe company?
It is not licensed in your state, but it has to be eligible there, and NAIC says the surplus lines broker is responsible for checking that. Under the NRRA, a state cannot block a placement with a non-U.S. insurer on the NAIC Quarterly Listing of Alien Insurers, and California publishes its own List of Approved Surplus Line Insurers. NAIC reports the insolvency rate of surplus lines insurers is historically low.
Will the state guaranty fund pay my claim if a surplus lines carrier fails?
No. NAIC and Washington’s insurance commissioner both say guaranty fund protection is not available for surplus lines policies, Texas notes surplus lines insurers do not have to be members of its guaranty association, and California makes you sign a disclosure acknowledging it when you apply. The carrier’s own financial strength is what stands behind the claim.
Can I pick surplus lines just because the quote is lower?
Not in most situations. The broker has to document that the admitted market was tried first; California and New York both set the standard at three admitted declinations. The exceptions are coverages on a state’s export list and exempt commercial purchasers under the NRRA who request a nonadmitted placement in writing.
My business operates in several states. Whose surplus lines rules apply?
Your home state’s. Under the NRRA, that is where you keep your principal place of business, or, if none of the risk is there, the state with the largest share of the premium. Only that state can require the surplus lines premium tax.
Does admitted or surplus lines change my certificate of insurance?
The certificate names the carrier either way. Some contracts and lenders I see specify an admitted carrier or a minimum financial rating, so read the insurance clause before binding and tell me what it asks for.
