What Is Self-Insurance? Complete Guide for Businesses 2026

Self-insurance is how most large US employers already handle at least one major risk, since self-funded health plans cover 67% of covered workers and 80% of those at firms with 200 or more employees.
Retaining liability or workers’ compensation risk works the same way, with losses coming out of reserves you funded instead of a carrier’s balance sheet. A vendor-caused loss inside that retained layer has no carrier to absorb it, which turns your vendor insurance requirements into your primary loss control.
Self-insured vendors create the opposite problem, handing you a state certificate of authority or a letter of self-insurance instead of an ACORD form. You verify them by checking the approval behind the document, since no policy exists to check.
What Self-Insurance Is
Self-insurance is the practice of retaining a risk yourself instead of transferring it to a carrier. You pay claims from your own funds, hold reserves against future losses, and take on the administrative work a carrier would otherwise handle.
Self-insurance looks like a binary choice from the outside, with a company either buying a policy or writing checks from cash on hand. Almost nobody operates at either extreme, though. Retention is more of a spectrum, and the structures in the middle account for nearly all of it:
| Structure | How risk is retained | Policy in place | Who administers claims |
|---|---|---|---|
| Full self-insurance | Organization pays all covered losses from its own funds | None | In-house staff or a contracted administrator |
| Self-insured retention | Organization pays losses up to a set amount per claim, with excess coverage above it | Excess or umbrella policy above the retention | Organization or its administrator inside the retained layer |
| Self-funded health plan | Employer pays employee medical claims from its own assets | Stop-loss policy above the retained claims | Third-party administrator |
| Single-parent captive | Subsidiary insurer formed to insure only its own parent | Policy issued by the captive | Captive staff or a third-party administrator |
| Group captive | Multiple unrelated organizations pool risk in a jointly owned insurer | Policy issued by the captive | Shared administrator |
| Rent-a-captive or cell | Organization uses a captive it doesn’t own, with assets segregated in a protected cell | Policy issued through the cell | Cell facility operator |
| Fronting arrangement | Licensed carrier issues the policy and the captive reinsures it back | Fronting policy, collateralized | Fronting carrier or the captive |
Captives belong on that list for a reason. The National Association of Insurance Commissioners (NAIC) describes a captive as essentially a form of self-insurance where the insurer is owned wholly by the insured. That definition fits a single-parent captive exactly. Group captives and cell arrangements spread ownership among members or leave it with a facility operator, while participants still fund the losses themselves.
Every type of captive issues real policies backed by reserves its owners or participants funded, so the risk stays with the organizations that created it while a counterparty still receives a policy it can accept. Because the captive is a licensed insurer, it can buy reinsurance directly, even when you rent space in it instead of owning it.
Retention has a technical meaning here, which is the portion of any loss you pay before outside coverage responds. Every deductible on every policy you hold is a retained layer, so an organization carrying a $25,000 property deductible is self-insuring the first $25,000 of every property loss. Scale that concept up and you arrive at a self-insured retention, which applies the same logic to far larger amounts.
What Employers Are Actually Required to Carry
Federal law does not require employers to carry workers’ compensation, disability, or unemployment insurance. It’s the states that mandate workers’ compensation, each of which administers its own program with its own rules. Only a handful of states require disability coverage, while unemployment insurance operates as a federal-state program funded through employer payroll taxes instead of a policy that companies must purchase.
Texas is the exception on workers’ compensation, since private employers there can decline coverage entirely. The Texas Department of Insurance calls these employers non-subscribers. Coverage normally makes workers’ compensation an injured employee’s exclusive remedy, which bars a negligence lawsuit against the employer. Non-subscribers lose that protection. Texas law also bars a non-subscriber from blaming the injury on the employee’s own carelessness, on a risk the employee knowingly accepted, or on a coworker’s negligence. The employee still has to prove the employer was negligent.
State authority over workers’ compensation is what makes self-insuring it a regulated activity. Each state decides who qualifies, what they post as security, and what happens when an approved self-insurer stops meeting the standard, which the regulatory section below covers in detail.
Self-Insured Retention
A self-insured retention is an amount you pay on each claim before your excess policy responds. Organizations carrying a $250,000 SIR under a $10 million excess tower are self-insuring the first $250,000 of every loss, whether or not anyone at the company describes it that way.
Inside a retention, you handle the claim. You hire the adjuster, you direct the defense, you decide what to settle, and your excess carrier watches without participating until the loss reaches their attachment point. A deductible works the other way, since your carrier handles the claim from the start and bills you for the deductible portion afterward. That control is part of why organizations choose an SIR, and the administrative obligation attached to it is part of why others don’t.
Sizing the retention is where organizations can make an expensive mistake, because a number that looked right at renewal three years ago may not provide adequate protection today. General liability claim severity reached $101,000 in 2024, up 45% from $70,000 in 2020, based on carriers reporting through the ISO Statistical Plan. A retention set against 2020 loss experience caps your share of each claim at the same dollar amount it did then, while the average claim has grown 45%. Your company pays more on the typical claim inside that retention, often without anyone noticing the shift.
Your excess tower has the same problem from the other direction. Losses that would have stayed within the retained layer five years ago now reach the excess carrier more often, which affects your excess pricing at renewal and could eventually affect whether that carrier wants the account.
Above the retention, your excess or umbrella policy takes over. A retention typically applies per occurrence, so you pay up to the full retention amount on every claim. A year with several large losses costs you that amount several times over.
Some programs cap your total with an annual aggregate retention, after which excess coverage responds to further claims without another retained layer. Confirm which structure you hold before you set the retention amount, since your exposure under a per-occurrence retention has no annual ceiling.
Self-Funded Health Plans
A self-funded health plan pays employee medical claims from your organization’s own assets instead of transferring that risk to an insurer. You contract a third-party administrator to process claims and provide network access, you fund the claims as they come in, and you carry the year’s medical spend on your own books.
Employees rarely notice. The ID card carries a familiar insurer’s logo, because the large carriers administer self-funded plans alongside the policies they sell, and the network, the claims process, and the customer service line work the same way.
How ERISA Changes the Rules
The Employee Retirement Income Security Act preempts state insurance regulation for self-funded health plans. That preemption changes four things about how your plan operates:
- No state approval: No agency reviews your plan or authorizes you to operate it, unlike workers’ compensation self-insurance where a state grants or withholds permission.
- No state benefit mandates: You design coverage without following each state’s list of required benefits. Federal rules still apply, including preventive care without cost sharing, the ban on annual and lifetime dollar limits, mental health parity, and protection against surprise medical bills.
- No state premium tax: Fully insured employers pay that tax through their premium. You avoid it on the claims your plan pays directly, though the stop-loss policy above your plan is insurance and generally carries the tax.
- One plan design everywhere: Multi-state employers apply the same benefits and the same documents in every state, instead of managing separate arrangements shaped by fifty different mandate lists.
You take on fiduciary responsibility in exchange. ERISA makes your organization a plan fiduciary, obligating you to administer the plan in participants’ interest and exposing you to claims when you don’t.
Stop-Loss Insurance
Stop-loss coverage caps what a self-funded plan can cost you in a year, and no employer should run one without it. A single catastrophic claimant can generate seven figures in medical spend, which is the kind of loss that ends the argument for self-funding permanently.
Two forms cover two different failure modes:
- Specific stop-loss: Caps your exposure on any one claimant, attaching at a per-person threshold you select. A premature infant, a transplant, or a cancer course crosses that threshold and the stop-loss carrier funds everything above it.
- Aggregate stop-loss: Caps your total plan-year spend across all claimants. Nobody needs a catastrophic claim for this to matter, since a year where ordinary claims run 25% above projection produces the same budget problem through volume.
Carrying only specific coverage leaves the volume risk open, which is why most programs buy both. The attachment points you choose determine your premium and your retained exposure, and setting them too high to save premium defeats the purpose.
Level-funded plans package a small self-funded component with stop-loss attaching at low thresholds, which is how self-funding reaches employers too small to absorb real claims volatility. Those arrangements look like self-insurance on paper and behave much closer to an insured plan in practice.
What This Means When You Verify a Vendor
A vendor telling you they’re self-insured may be describing their health plan and nothing else. That statement carries no information about their general liability coverage, their auto coverage, or their workers’ compensation status.
Ask which risks they retain. A company self-funding health benefits while buying conventional liability coverage is entirely ordinary, and so is the reverse. The phrase covers too much ground to accept on its own.
Captive Insurance
A captive is an insurance company you own, formed to insure the risks of its own parent or members. You capitalize it, it issues policies, it holds reserves, and it answers to a regulator in whatever domicile licensed it. The structure keeps risk within your corporate family while giving you a licensed insurer that can issue policies and access reinsurance markets directly.
Four structures cover nearly every type of captive insurance arrangement:
| Structure | Who owns it | Who it insures | Best suited to |
|---|---|---|---|
| Single-parent captive | One organization | That organization and its affiliated companies | Organizations with enough loss volume to support their own insurer |
| Group captive | Multiple unrelated organizations | Its member-owners | Mid-sized organizations sharing formation costs and governance |
| Rent-a-captive | A third-party facility | Participants who use it without owning it | Organizations that want captive economics without formation |
| Protected cell | A cell facility operator | The cell participant, with assets legally segregated | Participants that need statutory separation from other users |
Is a Captive Worth It?
A captive might be a good idea if your loss volume is predictable enough to fund internally and large enough to justify the overhead, which in practice means organizations with sustained premium spend and stable claims experience. Everyone else is usually better served by a cell, a group arrangement, or a conventional policy.
Marsh formed 118 new risk retention entities in 2025, up from 92 the prior year, with managed captive premium reaching $79.1 billion. Commercial rates softened by 4% that same year, which weakened the conventional financial argument for retention and makes the increase more interesting than it appears. Organizations already inside a captive increased their retentions by 4% while ceding less to reinsurance, dropping from $13.4 billion to $11.5 billion.
Fronting Arrangements
A fronting arrangement puts a licensed carrier’s name on the policy while your captive or your own program reinsures the risk back. The carrier issues the paper and handles the regulatory filings. You keep the economics and the risk.
Organizations front for reasons that have nothing to do with risk appetite:
- Counterparties demand admitted paper: A customer, landlord, general contractor, or lender requiring an ACORD certificate from a rated carrier gets one, since a fronting carrier issues certificates the way it would for any policyholder.
- States require admitted coverage: Auto liability and workers’ compensation coverage has to come from a carrier licensed in the state unless the organization holds that state’s self-insurance approval. A captive typically has neither, so a fronting carrier issues the policy in its place.
- Offshore captives need US access: A captive domiciled in Bermuda or Cayman can’t write US risks directly, so a fronting carrier writes the policy and cedes it back through reinsurance.
What Fronting Costs
The fronting carrier charges a fee, usually calculated as a percentage of premium, for lending its license and handling the filings.
The fronting carrier remains legally responsible for paying claims if your captive fails to fund the reinsurance, so they require security against that credit risk. That security typically costs you more than the fronting fee, and it stays committed for as long as claims from that policy year remain open.
Most fronting carriers accept a letter of credit, which uses up credit your bank would otherwise make available to you for other purposes. Cash in a trust account avoids the bank but earns you nothing while it waits, and a surety bond requires an annual payment to the surety company for as long as it stays in place. Some carriers instead withhold the premium they would have ceded back to your captive and hold it as security.
Why Fronting Matters When You Verify a Vendor
A self-insured vendor handing you a clean certificate from an A-rated carrier may be running a fronted program. The certificate is genuine, the carrier is real, and the vendor retains the risk behind it through reinsurance.
That arrangement creates no problem for you, since the fronting carrier owes the claim regardless of what happens to the vendor’s captive. It does change what the carrier’s rating tells you. An A rating describes the fronting carrier’s financial strength, not the financial condition of the entity actually funding the loss.
Ask whether reinsurance or a captive arrangement stands behind the policy when a vendor describes itself as self-insured while producing conventional certificates. Both things can be true at once.
Self-Insured Workers’ Compensation Requirements by State
You need a state agency’s approval before you can self-insure workers’ compensation, and that approval covers one state only. An employer operating in twelve states applies separately in each state that permits self-insurance, clearing a different set of financial thresholds and posting security every time.
North Dakota doesn’t permit self-insurance at all, since state law makes Workforce Safety and Insurance the only provider of workers’ compensation coverage there. Wyoming takes the same approach for industries it classifies as extrahazardous, which must carry coverage through the state fund.
Wyoming doesn’t require workers’ compensation from employers outside those industries, nor does it regulate self-insurance for them. A vendor claiming self-insured status for work in either state has no state approval behind the claim, since neither state grants one.
State Approval and What It Requires
Workers’ compensation approval is the demanding one, requiring audited financial statements covering several years, a claims administrator under contract, and a security deposit held against the possibility that you stop paying claims. Texas, Nevada, and New York also require excess coverage above your retention.
Organizations can easily underestimate the deposit as it’s committed capital that earns nothing for you. The state reviews it each year and raises it as your liabilities grow. For example, New York’s minimum for workers’ compensation self-insurers rose to $1,999,000 effective July 1, 2026, with every self-insurer adjusting to whatever level the Board determines from their annual reports.
Every entity must also file its own application in New York. Subsidiaries are not automatically covered when a parent company holds approval, which means a vendor claiming self-insured status under a corporate parent may hold no authorization for the entity signing your contract.
State Requirements for Self-Insured Workers’ Compensation
Thresholds vary enough that self-insured status tells you which states approved an organization instead of anything reliable about its balance sheet:
| State | Financial threshold | Security deposit | Excess coverage |
|---|---|---|---|
| California | Net worth of $5M, net income of $500K per year | Required, amount set by the state | Not required by the state |
| Texas | $500K Texas premium or $10M nationwide, plus a qualifying rating or $5M tangible net worth at 1.5:1 | At least $300,000 | At least $5M per occurrence |
| Nevada | Tangible net worth of $2.5M | At least $100,000, based on claims history | Required against catastrophic loss |
| New York | Set by Board review of financial condition | $1,999,000 minimum from July 2026 | Required by regulation |
A company qualifying comfortably in Nevada at $2.5 million in tangible net worth would fail Texas outright. Texas requires either $500,000 in Texas workers’ compensation premium or $10 million nationwide before it considers the application, plus a $1,000 non-refundable fee and a signed contract with a qualified claims servicing contractor.
Texas won’t issue a certificate of authority to self-insure unless the applicant carries at least $5 million per occurrence in excess coverage. Nevada attaches a similar condition, requiring evidence of excess insurance against catastrophic loss, and New York imposes its own excess requirement by regulation. An approved workers’ compensation self-insurer in any of the three states has a carrier above its retention.
What Happens When You Leave the Program
Withdrawing from a self-insurance program ends your approval and none of your liability. California has 8,579 former self-insured employers still paying claims from periods that already closed, against 7,049 employers currently active. More organizations are funding old self-insured claims than are self-insuring today.
Workers’ compensation claims explain the imbalance. A back injury reported in 2014 can still be paying indemnity and medical benefits in 2026, and permanent disability awards run for decades. An employer who self-insured for six years and then bought a policy owns every claim from those six years until the last one closes.
Your security deposit stays posted the entire time, your annual reports keep coming due, and the agency continues verifying that reserves cover what’s left. Organizations modeling self-insurance as a year-by-year decision miss this entirely, because the exit takes longer than the participation did.
Self-Insured Auto Liability
Organizations with vehicle fleets can self-insure auto liability through a state agency, usually the motor vehicle department, which issues a certificate of self-insurance entirely separate from any workers’ compensation approval. A vendor holding one has satisfied a single state that it can pay judgments arising from its vehicles.
Who Qualifies to Self-Insure Auto Liability
Eligibility turns on fleet size in three of these four states, with financial tests layered on top:
| State | Agency | Fleet threshold | Financial requirement | Excess coverage |
|---|---|---|---|---|
| California | Department of Motor Vehicles | More than 25 registered vehicles | Net worth of at least $2.2 million | None required by statute |
| Texas | Department of Public Safety | More than 25 registered vehicles | None in statute, with approval resting on the agency’s finding that the applicant can pay judgments | None required by statute |
| New York | Department of Motor Vehicles | More than 25 registered vehicles | Liquidity and equity tests calculated per vehicle | At least $5 million, or $10 million for fleets with larger for-hire passenger vehicles |
| Florida | Department of Highway Safety and Motor Vehicles | None | Net unencumbered worth of $40,000 for the first vehicle and $20,000 for each additional one | Optional, as an alternative to higher net worth |
Florida sets no fleet minimum at all, allowing a private individual with a single passenger vehicle to self-insure on $40,000 of net unencumbered worth. A Florida certificate therefore tells you nothing about the size of the operation behind it. In Texas, the statute assigns the program to the Department of Public Safety instead of the motor vehicle department, so that’s the agency to contact.
What an Auto Self-Insurance Certificate Proves
The certificate evidences the state’s minimum financial responsibility limits and nothing above them. Florida’s procedure manual shows the certificate printing limits of $10,000/20,000/10,000, matching the statutory minimum. Texas binds its self-insurers to the same judgments a minimum owner’s policy would pay, which works out to $30,000/60,000/25,000.
A vendor answering your $1 million auto requirement with a Florida or Texas certificate has proven coverage at a fraction of that amount, unless they also produce an excess policy. New York requires every self-insured fleet to carry an excess policy of at least $5 million, which puts a commercial carrier above the retained layer and gives the certificate far more behind it than the minimum limits alone would.
What to Confirm When a Vendor Self-Insures Its Fleet
None of these agencies offers a public lookup for approved auto self-insurers, so confirming a certificate means contacting the agency that issued it. Check these four points before you accept one:
- The issuing state: A certificate covers vehicles registered in the state that issued it, so ask where the vendor’s fleet is actually registered.
- The expiration date: Florida certificates expire after one year and New York renews on an annual cycle, so an older certificate may no longer be in force.
- The vehicles covered: Florida schedules each vehicle individually on the certificate, so a truck added after issuance may fall outside it.
- The excess policy: Request the certificate for any excess coverage above the retained limits, since that policy decides whether the vendor meets a contract requirement above the state minimum.
When Self-Insurance Makes Sense
Retention works for losses you can predict and absorb. High-frequency, low-severity claims fit that description, because enough of them happen each year to make the total reasonably forecastable. Catastrophic exposure fails it completely, since a single loss can exceed whatever you reserved.
Six factors decide which side of that line your exposure falls on:
| Factor | Favors retention | Favors transfer |
|---|---|---|
| Loss predictability | Stable frequency and severity over several years | Volatile or thin claims history |
| Loss size | Individual claims your balance sheet absorbs without strain | Any exposure capable of a severity outlier |
| Cash flow | Capital available to fund claims and post security | Premium payments preferred over reserves and deposits |
| Claims control | Value in directing defense and settlement decisions | No appetite for claims administration |
| Administrative capacity | Risk management staff or budget for a third-party administrator | Neither available |
| Regulatory tolerance | Willingness to maintain approvals and annual filings | Preference for a carrier handling compliance |
Claims history misleads most dangerously when it looks stable. Three years of predictable losses tell you little about a fourth year that includes a fatality or a single claimant needing a transplant, and events like those don’t average out over time. An organization with thin loss data carries exactly that risk, because the pattern it relies on hasn’t existed long enough to include the outlier. You’re betting your reserves that the outlier stays away whenever you retain exposure capable of producing one.
Do Self-Insured Programs Actually Save Money?
Often, though less reliably than the usual figures suggest. AM Best-rated US captives posted a five-year average combined ratio of 88.0 against 97.0 for their commercial casualty peer composite, and that nine-point advantage is the number captive advocates quote.
The 2024 result was 98.5, a 9.6-point deterioration from 2023 that put the composite within striking distance of underwriting break-even. Net income fell 14% to $1.3 billion that year.
Retention moves volatility from a carrier’s balance sheet onto yours, so the savings arrive unevenly and you absorb a bad year in full. Across 2019 through 2024 the composite added $4.6 billion to surplus and returned $2.0 billion in dividends, representing $6.6 billion in retained cost savings over six years that included 2024.
Tax timing works against retention, since premiums you pay a carrier are deductible as an ordinary business expense in the year you pay them. Money you set aside in self-insurance reserves earns no deduction until you pay the claim, because federal tax rules treat workers’ compensation and tort liabilities as incurred only when payment reaches the injured party.
That timing difference gives organizations a tax reason to consider a captive, whose premiums are deductible only when the arrangement qualifies as insurance. The IRS tests that by asking whether risk actually shifted to the captive and whether the captive pools enough risk that the parent isn’t simply paying for its own losses.
The Costs That Erode the Savings
A self-insured program needs claims administration, handled in-house or by a contracted administrator, along with actuarial analysis establishing reserves, annual audits satisfying the state, and a security deposit held as committed capital. Those costs continue in years when your losses come in low, which is precisely when the program looks like it’s working.
Your security deposit carries a yearly cost on top of the capital it ties up. New York and Texas both accept a letter of credit, which uses up credit your bank would otherwise make available to you and charges an annual fee. A surety bond requires an annual payment to the surety company instead, while posting cash avoids both fees and earns you nothing for as long as the state holds it. Build that cost into any comparison against premium savings.
Excess coverage adds another line. Texas, Nevada, and New York require it. Your own risk tolerance should demand it in states that don’t, so the premium you avoided on the primary layer partially reappears above your retention. Organizations modeling retention against their full premium spend instead of against the primary layer alone tend to find the math tighter than expected.
How Self-Insured Organizations Evidence Their Own Coverage
A state agency issues self-insured organizations a certificate of authority confirming their approval to retain risk. The organizations themselves issue counterparties a letter of self-insurance describing which risks they retain and to what limits. Public entities that pool their risk add a third document, the memorandum of coverage.
The State Certificate of Authority
A certificate of authority confirms that a regulator examined an organization’s finances and authorized it to pay its own claims. Texas grants it after the applicant clears the financial thresholds, posts the security deposit, and contracts a qualified claims servicer, and other states run comparable processes under their own labels.
What it gives you is confidence in the organization’s approved standing. What it doesn’t give you is any information about limits, endorsements, or what happens when a loss involves you.
The Letter of Self-Insurance
Self-insured organizations produce this one themselves. The University of California partners with a broker to issue certificates evidencing its self-insured coverages, and public universities publish annual self-insured letters alongside conventional certificates for the lines they buy commercially.
A conventionally insured vendor who produces their own certificate has bypassed the only parties authorized to issue one, and several states make issuing a false certificate a criminal offense. A self-insured vendor producing their own letter is doing the only thing available to them, because no carrier exists to issue anything on their behalf.
What the Letter Should Contain
Only accept a letter that names the self-insured entity as it appears on your contract, states which risks the organization retains, identifies the states where it holds authorization, and gives the limits it self-insures to. Most also name the claims administrator and the excess carrier above the retention.
Compare that against what an ACORD certificate delivers and the difference in verification burden becomes obvious. One comes from a licensed third party with standardized fields, while the other comes from the party you’re evaluating.
Memoranda of Coverage From Public Entities
Cities, counties, school districts, and special districts that pool their risk evidence coverage with documents the pool issues itself, usually a memorandum of coverage backed by a certificate of participation. Neither document is an insurance policy, so the reading habits you apply to an ACORD certificate won’t transfer.
Special districts alone account for 40,199 of the country’s 91,438 local governments, which puts memoranda of coverage in front of anyone contracting with a transit authority or water district.
California law states that pooling self-insured losses among public entities shall not be considered insurance or regulated under the Insurance Code. The California Joint Powers Insurance Authority repeats the point in its own memorandum, which states that the document “is not an insurance policy.” Colorado exempts pools from its insurance laws apart from narrow reporting duties, while Washington subjects them to oversight by a state risk manager.
Here’s how a pool’s coverage documents compare with a conventional policy:
| Insurance policy | Pool memorandum of coverage | |
|---|---|---|
| Issued by | A licensed insurance carrier | The pool its members formed |
| Regulated by | The state insurance department | Varies, with some states exempting pools from insurance law entirely |
| Proof you receive | ACORD certificate | Certificate of participation or coverage |
| Additional insured mechanism | An endorsement with a form number you can check | A letter from the pool granting “protected party” or similar status |
The protected party letter behaves like a blanket additional insured endorsement without the standardized language. CJPIA grants the status only where a written agreement requires it, limited to whatever activity and time period the letter names. No ISO form number exists to confirm what it covers.
Ask the pool for the letter itself and read it alongside the memorandum, because certificates of participation point back to the pool’s bylaws and intergovernmental agreement as the documents that govern coverage.
Verifying a Self-Insured Vendor
You verify a self-insured vendor by checking the approval behind its retention instead of a policy. No carrier issues coverage for the retained layer, so you won’t find an AM Best rating or an ACORD form for it. Every question you’d normally ask about a certificate becomes a question about the vendor’s authorization.
What to Confirm
Check their authorization, confirm its scope, and verify the coverage above their retention:
- The state certificate of authority: Get the document itself and the name of the issuing agency. Most state workers’ compensation authorities publish lists of approved self-insurers, so you can confirm current status directly.
- Which states approved them: Authorization is state by state. A vendor approved in Nevada performing work for you in Texas is not self-insured for that work.
- The entity holding the approval: Match it against the entity on your contract. New York and other states require each entity to apply separately, so a subsidiary doesn’t inherit a parent’s authorization.
- The excess coverage above their retention: Texas, Nevada, and New York require it, which means a real carrier stands above the retention. Request that certificate the way you would for any vendor.
- The claims administrator: Find out who handles losses and how you reach them, because the vendor’s own staff may not be the answer.
When “Self-Insured” Means Uninsured
Some vendors call themselves self-insured when they hold no approval and carry no coverage, using the phrase to describe going without insurance entirely. Retaining general liability requires nobody’s permission, so the claim sounds plausible until you ask how the vendor would actually pay for a loss.
An organization that actually retains its own risk can show you how it pays for that retention, while a company going bare has nothing to show. Ask for these four things:
- A state certificate of authority: Approved self-insurers for workers’ compensation or auto liability hold one and can name the agency that issued it. A vendor with employees that holds neither a policy nor an approval is out of compliance in any state that requires coverage.
- A claims administrator: Somebody handles the vendor’s losses, whether in-house staff or a contracted administrator, and the vendor can tell you who.
- An excess policy: Organizations that retain risk carry coverage above their retained layer, and that policy produces an ordinary certificate you can verify like any other.
- Financial statements: A vendor retaining risk can document the reserves or net worth funding it when the size of the contract justifies asking, though reading what those statements actually show is a vendor prequalification exercise rather than an insurance one.
Treat a vendor that produces none of these as uninsured, since no funded retention stands behind the phrase. Whatever their work damages then comes out of your own policy or your own retention, the same exposure that comes with any uninsured subcontractor.
When Additional Insured Language Breaks
An additional insured endorsement adds a party to an insurance policy. A vendor retaining risk directly, without a captive or a pool behind it, has no policy in that layer, so nothing exists to add you to.
Captive-backed vendors are different, since the captive issues an actual policy that can carry additional insured endorsement. A public entity pool can grant protected party status by letter instead. Ask which structure stands behind a vendor’s retention before you decide which requirements it can meet.
A waiver of subrogation still works against a self-insured vendor, because the vendor holds the underlying right itself. A vendor that pays its own loss can pursue whoever caused it. Approved workers’ compensation self-insurers typically hold the same statutory reimbursement rights against a negligent third party that a carrier would. No policy exists to endorse, so write the waiver into the contract itself, covering the recovery rights the vendor holds directly.
When you require additional insured status on a primary and noncontributory basis, you’re asking for something a vendor retaining risk directly can’t deliver for that layer, since no policy exists to carry the endorsement. You’ll also need to redraft the waiver of subrogation as a contract term instead of an endorsement reference.
What to Require Instead
Contractual indemnification carries the weight here, since it obligates the vendor directly instead of routing through an insurance mechanism that doesn’t exist. Draft it to reach the exposures an additional insured endorsement would have covered, and expect the negotiation to be real.
Request the excess policy certificate separately, because the additional insured requirement does work above the retention, where a carrier writes the coverage. Add a notice obligation covering any lapse, suspension, or revocation of the state authorization, with a defined number of days and a consequence attached. Drafting around the absence of those endorsements gets easier once you know what additional insured and named insured status actually accomplish when a policy exists.
Why Self-Insured Organizations Need Tighter Vendor Compliance
Retention makes vendor insurance more important to you, not less. A vendor causes a loss on your site, and where you carry a policy, your carrier absorbs it and the premium you already paid covered that possibility. Where you retain the risk, the money comes out of reserves you posted against your own claims.
California’s private self-insured employers hold $4.4 billion in estimated claims reserves against 89,079 open workers’ compensation cases. Every dollar a vendor-caused loss pulls from a program like that is a dollar reserved for something else, with no carrier standing behind it and no premium already committed to absorb it.
Risk transfer to vendors stops being a backstop under those conditions. It becomes the primary loss control instrument, and the compliance program enforcing it carries weight that a conventionally insured organization can afford to treat more casually.
A missing certificate costs a self-insured company more than it costs a conventionally insured one. At the insured company, the carrier handles the resulting claim and the damage shows up as a difficult conversation at renewal. At the self-insured company, the claim comes out of its own reserves, which can prompt the state to raise its security deposit.
CertFocus by Vertikal RMS handles that verification at the depth retention demands. Vendors upload their own documents, Hawk-I AI processes each certificate, and a licensed insurance professional decides whether the coverage satisfies your requirements. Expiration tracking continues across the full vendor population, which matters because a certificate confirms coverage at the time somebody issued it and nothing beyond that.
What Self-Insurance Changes About Vendor Verification
Self-insurance covers every arrangement where your organization pays a loss instead of a carrier, including deductible, self-insured retentions, self-funded health plans, and captives. Each structure answers to its own rules. Self-insuring workers’ compensation or auto liability requires approval from each state where you operate. Texas is the exception for workers’ compensation, since private employers there can opt out of the system as non-subscribers and give up the liability limits that coverage provides.
Verifying a self-insured vendor starts with identifying the structure behind the phrase. A captive-backed vendor can produce a real policy, and a public entity produces a memorandum of coverage. A vendor retaining risk directly can show you a state certificate of authority and an excess policy, while an employer self-funding its health plan has told you nothing about its liability coverage. A vendor who can produce none of those documents is describing an uninsured operation.

FAQ
Self-insurance is paying your own claims instead of buying a policy that pays them for you. You hold reserves, handle claims administration, and absorb losses directly. Many self-insured organizations also buy excess coverage above the retained layer. Texas, Nevada, and New York require it before approving workers’ compensation self-insurance.
A self-insured company retains part of its own risk rather than transferring it to a carrier. For workers’ compensation, it means a state agency reviewed their finances and authorized them to pay claims directly. They post a security deposit, contract a claims administrator, and file annual reports proving they can still cover their liabilities.
Sometimes, and less reliably than the savings figures suggest. AM Best-rated US captives averaged a combined ratio of 88.0 over five years against 97.0 for commercial casualty peers, but the 2024 figure deteriorated to 98.5. Retention moves volatility onto your balance sheet, so savings arrive unevenly and you absorb a bad year in full.
A self-insured retention is the amount you pay on every claim before excess coverage responds. Inside that layer, you hire the adjuster, direct the defense, and decide what to settle. Your excess carrier participates only once a loss reaches their attachment point.
Largely, yes. The NAIC describes a captive as essentially a form of self-insurance where the insurer is owned wholly by the insured, which matches a single-parent captive exactly. Group captives and cell arrangements let participants fund their losses without owning the whole insurer. Every captive issues actual policies and answers to a domicile regulator, which distinguishes it from retaining risk with no insurer involved.
Yes for workers’ compensation, and separately in every state where you operate. States require audited financials, a claims administrator, and a security deposit they review annually. Texas, Nevada, and New York also require excess coverage above your retention, while California does not. Thresholds vary widely. Nevada sets a minimum of $2.5 million in tangible net worth, while Texas requires either $500,000 in Texas premium or $10 million in premium nationwide.
A self-insured company sends you a letter of self-insurance it produces itself, backed by a certificate of authority a state agency issued to it. The letter describes which risks the organization retains and to what limits. The state certificate confirms a regulator reviewed its finances and approved the retention. No ACORD certificate exists for that layer, because no carrier issues one.
It depends on how the vendor retains risk. A vendor paying losses directly has no policy in that layer for an additional insured endorsement to attach to, though a captive-backed vendor can endorse you onto the captive’s policy. Above any retention, the excess carrier’s policy accepts the endorsement normally, so request that certificate separately.
Yes. Verify the state certificate of authority and confirm which states approved them and which entity holds the approval. Request the excess policy certificate. Draft an indemnification provision that obligates the vendor directly instead of routing through endorsements that can’t attach, and require notice if the state authorization lapses.
