Admitted vs non-admitted insurers: what the difference means
Admitted insurers are licensed in your state and backed by its guaranty fund. Non-admitted (surplus lines) insurers are not. What that changes for your policy.
An admitted insurer holds a license (certificate of authority) in your state, is generally subject to the state's rate and form filing rules, and its policies are backed by the state insurance guaranty fund. A non-admitted insurer is not licensed in your state; it writes coverage there under the state's surplus lines law, usually through a licensed surplus lines broker, with more freedom over rates and forms and without guaranty fund protection. Non-admitted does not mean unregulated or unsound, but it does change who protects you if something goes wrong.
The two kinds of non-admitted insurer
- Surplus lines insurers. Companies licensed in their home state (or admitted in other states) that are not admitted in yours. They must be "eligible" under your state's rules to take surplus lines business.
- Alien insurers. Insurers domiciled outside the United States, including Lloyd's syndicates. The NAIC maintains a Quarterly Listing of Alien Insurers, overseen by its International Insurers Department, and under the NAIC model act a non-U.S. insurer must be on it to write surplus lines (NAIC, Surplus lines). See Lloyd's and How Lloyd's of London works: syndicates, brokers and what it means for you.
An insurer can be admitted in one state and non-admitted in another. The question is always status in the state where the risk or the insured's home sits.
Side by side
| Feature | Admitted insurer | Non-admitted (surplus lines) insurer |
|---|---|---|
| License in your state | Yes | No; must be on the state's eligible list or the NAIC alien listing |
| Rates and forms | Filed or approved under the state's system; see commercial rate filing: prior approval, file-and-use and deregulation | Generally not filed or approved; the insurer can write manuscript or custom terms |
| Guaranty fund | Yes, within state caps (most states cap P&C claims at $300,000, and workers' comp is generally outside the cap, per the NCIGF) | No; NAIC says guaranty fund coverage is not available for surplus lines |
| Who places it | Agent, broker or directly with the insurer | A licensed surplus lines broker, after a diligent search in most cases |
| Taxes and fees | Insurer pays premium tax | Surplus lines premium tax and often a stamping fee, collected from the insured through the broker; see surplus lines taxes, stamping fees and diligent search |
| Typical use | Standard risks | Risks the admitted market declines or cannot price within its filed rates |
State rules vary. Some states have a diligent search requirement, others an "export list" of classes that can go straight to surplus lines, and the tax rates differ. The regulator for your state is your starting point; see state insurance departments and what they can do for businesses.
Why the non-admitted market exists
Admitted insurers operate inside filed rates and approved forms, which makes it hard to cover new, unusual or high-hazard exposures, or accounts with bad loss history, at a price that works. The NAIC describes surplus lines as covering risks not available in the admitted market, often with limited loss history, which makes them difficult to price with common actuarial methods. That includes coastal and wildfire property, roofing contractors, habitational property, cannabis, some professional classes, large limits and emerging risks. See Declined for coverage? Where hard-to-place businesses find insurance and excess and surplus lines insurance explained.
The segment is large. According to AM Best's annual surplus lines report, published on September 11, 2026 and summarized by Insurance Business, surplus lines direct premium written reached a record $143.3 billion in 2025, up 10.4% from $129.8 billion in 2024. AM Best put general liability surplus lines premium at more than $51 billion, or 39% of the P&C industry's general liability volume, and the segment's share of commercial lines premium at 27.5% (Insurance Business). Surplus lines is a mainstream part of commercial insurance, not a fringe.
What federal law changed in 2010
The Nonadmitted and Reinsurance Reform Act of 2010 (part of Dodd-Frank) made the insured's home state the single state whose law and premium tax apply to a surplus lines placement, even when the risks sit in several states. The home state is generally the state of the insured's principal place of business; if the entire risk lies elsewhere, it is the state with the largest share of taxable premium (15 U.S.C. § 8206). Premium tax is allocated among states.
The act also defines an exempt commercial purchaser, a buyer large enough that a state may not require a diligent search, provided the broker discloses that admitted coverage may be available and the buyer asks in writing for the surplus lines placement. Under 15 U.S.C. § 8206(5), the buyer must have a qualified risk manager and have paid more than $100,000 in commercial property and casualty premiums nationwide in the previous 12 months, and meet one of several size tests: net worth above $20 million, annual revenue above $50 million, more than 500 full-time-equivalent employees (or an affiliated group with more than 1,000), a nonprofit or public entity with budgeted expenditures of at least $30 million, or a municipality with a population over 50,000. Those dollar amounts are indexed to inflation every five years, so ask your broker for the current adjusted figures.
How a surplus lines placement works
- The retail broker or agent tries the admitted market. The account is declined, or the quoted terms cannot meet the need.
- A licensed surplus lines broker places the risk. In practice that is usually a wholesale broker working with the retail broker; see wholesale brokers and surplus lines placement: how hard risks get insured.
- A diligent search is documented where the state requires one: the number of admitted declinations differs by state, and exempt commercial purchasers are generally excused.
- The insured is told in writing. NAIC's Non-Admitted Insurance Model Act (Model 870) provides that the insured is advised that the insurer is not licensed in the state and that, if it becomes insolvent, the guaranty fund will not pay claims. States adopt their own wording, and the notice is often a separate page attached to the policy.
- The broker files and pays tax. The broker reports the placement, collects the surplus lines tax and any stamping fee, and remits them. The Model Act also sets $15 million of capital and surplus, or the state minimum if greater, as the general eligibility test for a U.S. non-admitted insurer.
The trade-offs for the buyer
You may get coverage the admitted market will not write. For some businesses the choice is a surplus lines policy or no policy.
You give up guaranty fund protection. If an admitted insurer fails, the fund pays covered claims up to the state cap; see what happens when an insurer fails: guaranty funds and business policies. With a non-admitted insurer, a failure puts you in the insolvent estate's creditor line. The NAIC notes that surplus lines insolvencies have historically been rare, which it attributes to state solvency monitoring, but rare is not never. Check the insurer's financial strength; see AM Best ratings explained for business buyers and how to judge a business insurance company.
The forms vary more. Without filing rules, wording differs by insurer. Look for defense costs inside the limit, claims-made triggers, retroactive dates, designated-operations exclusions and sublimits. Read the exclusions before the coverage grant. See defense costs inside vs outside policy limits: why it matters and CGL exclusions: what a general liability policy does not cover.
Cancellation and nonrenewal rules differ. Notice periods and renewal rights that apply to admitted policies may not apply. Read the policy conditions, not just the cover letter.
Contracts may require an admitted carrier. Some leases, public-entity agreements and lender requirements say the insurer must be licensed or authorized in the state, or rated A- VII or better by AM Best. A surplus lines carrier may satisfy the rating but not the licensing clause. Check this before binding, and read how to review the insurance requirements in a contract.
A hypothetical example
Say a roofing contractor with 12 employees and two prior liability claims is declined by several admitted carriers for general liability. The facts are invented.
| Step | What happens |
|---|---|
| The retail agent submits to admitted markets | Declined; the roofing class is outside their appetite |
| A wholesale broker places the account with an eligible surplus lines insurer | Higher deductible, a roofing-specific exclusion, defense costs inside limits |
| The contractor receives the surplus lines notice | Policy states the insurer is not licensed in the state and that the guaranty fund will not pay |
| A general contractor customer's subcontract requires an admitted carrier | The contractor asks the customer to waive the licensing clause or finds another route; the certificate alone does not fix it |
| The policy is taxed and stamped | A surplus lines tax and any stamping fee appear as separate lines on the invoice |
How to check which kind you have
- Look for the surplus lines notice attached to or printed on the policy.
- Search the state insurance department's records. Most states publish lists of licensed and eligible surplus lines insurers.
- Ask the broker directly: "Is this insurer admitted in my state? If not, why did the admitted market decline it?"
- Check the rating and the financial size, and read the endorsements for sublimits.
- Compare quotes on a common sheet with the business insurance quote comparison worksheet.
Risk retention groups and captives are another category: licensed in one state and operating in others without being admitted there, and generally outside the guaranty funds. See Risk retention groups (RRGs): how they work and what to check.
Key takeaways
- Admitted means licensed in your state, with filed rates and forms and guaranty fund backing. Non-admitted means not licensed there, placed under the surplus lines law, with no guaranty fund.
- Non-admitted does not mean bad. It is where the market puts the risks the admitted market cannot or will not write, and it wrote a record $143.3 billion in 2025 according to AM Best.
- Under the 2010 federal act, the insured's home state governs the placement and the tax. Large buyers who qualify as exempt commercial purchasers can skip the diligent search.
- Weigh the trade-offs: more flexible coverage and capacity against no guaranty fund, more variable forms and tighter contract compatibility.
- Ask your broker whether an insurer is admitted, check its financial strength, and read the notice and exclusions before you bind.
