Self-Insured Employers: How to Verify Workers' Comp Compliance

Your vendor submits a certificate of insurance. The Workers' Compensation section is blank — no carrier, no policy number, no limits. Instead, the description of operations field reads: "Employer is qualified self-insured for Workers' Compensation in the State of [X]." Or perhaps the ACORD 25 shows "Self-Insured" in the workers' comp carrier column with a certificate number that does not look like a standard policy number.

Self-insured workers' compensation is legitimate, legal, and common among large employers. But verifying compliance for a self-insured vendor requires a completely different process than checking a standard WC certificate. This guide covers what self-insurance means, who qualifies, how to verify it, and what documentation to require.

What Is Workers' Comp Self-Insurance?

Workers' compensation self-insurance means that the employer does not purchase a WC insurance policy from a commercial carrier. Instead, the employer assumes the financial obligation to pay workers' compensation benefits directly to injured employees from its own funds.

Self-insurance is not the same as being uninsured. A self-insured employer has applied to the state, demonstrated financial capacity, posted security (typically a surety bond or letter of credit), and received formal approval to self-insure. The employer is legally obligated to provide the same benefits as any insured employer — the difference is that they pay claims from their own reserves rather than through an insurance carrier.

Why Employers Self-Insure

Large employers with predictable loss histories self-insure for several reasons:

• Cost savings. Insurance premiums include the carrier's overhead, profit margin, and risk loading. A large employer with a favorable loss history can pay claims for less than the premium an insurer would charge.
• Cash flow control. Self-insured employers pay claims as they occur rather than paying a large annual premium upfront.
• Claims management control. Self-insured employers (or their TPAs) manage claims directly, allowing for more aggressive return-to-work programs and fraud prevention.
• Experience rating control. Large employers can manage their workers' comp costs more directly through safety programs and claims management rather than being subject to carrier pricing models.

Who Qualifies for Self-Insurance?

Self-insurance is not available to every employer. Each state sets its own qualification requirements, but common criteria include:

Financial Capacity

The employer must demonstrate sufficient financial resources to pay anticipated claims. States typically require:

• Minimum net worth — ranging from $500,000 to $10,000,000 depending on the state
• Audited financial statements — demonstrating the employer's financial condition
• Actuarial analysis — projecting expected losses based on the employer's payroll, industry classification, and loss history
• Security deposit — a surety bond, letter of credit, or cash deposit, typically set at 100% to 150% of the employer's estimated annual losses

Employer Size

Most states require a minimum number of employees or minimum payroll to qualify. Thresholds vary: California requires 3 or more employees and proof of financial ability; New York requires a minimum net worth based on the employer's estimated annual claim obligations; Texas has a separate process because WC is not mandatory.

State Approval

Self-insurance requires a formal application to the state workers' compensation authority. The application is reviewed, the employer's financials are examined, and if approved, the state issues a Certificate of Self-Insurance (sometimes called a Certificate of Authority to Self-Insure). This certificate is the controlling document for verification purposes.

How to Verify Self-Insured Status

Standard COI verification does not work for self-insured employers. There is no insurance carrier to check, no policy to verify, and no standard ACORD 25 certificate that fully represents the self-insured status. Instead, use this verification process:

Step 1: Request the State Certificate of Self-Insurance

The primary verification document is the state-issued Certificate of Self-Insurance (or Certificate of Authority). This document confirms:

• The employer is approved to self-insure in the specific state
• The effective date and expiration date of the self-insurance authorization
• The certificate number assigned by the state
• Any conditions or limitations on the self-insurance authorization

Request a copy of this certificate directly from the vendor. It should be current — self-insurance authorizations are typically renewed annually or biennially.

Step 2: Verify with the State Authority

Most state workers' compensation authorities maintain a list of approved self-insured employers, often available online. Verify the vendor's self-insured status directly with the state:

• California: DIR Self-Insurance Plans (dir.ca.gov)
• New York: Workers' Compensation Board (wcb.ny.gov)
• Texas: Division of Workers' Compensation (tdi.texas.gov)
• Florida: Division of Workers' Compensation (myfloridacfo.com)
• Illinois: Illinois Workers' Compensation Commission (iwcc.il.gov)
• Pennsylvania: Bureau of Workers' Compensation (dli.pa.gov)

If the state does not publish a list, contact the workers' compensation authority by phone or email to confirm the vendor's self-insured status.

Step 3: Verify the Security Deposit

Self-insured employers are required to post security (surety bond or letter of credit) with the state. The security amount is set by the state based on the employer's projected claims liability. While you typically cannot access the security deposit amount, confirming that the state has approved the self-insurance authorization implies the security requirement has been met.

Step 4: Review Excess / Stop-Loss Coverage

Most self-insured employers purchase excess workers' compensation coverage (also called specific stop-loss and aggregate stop-loss) to cap their per-claim and total annual exposure.

• Specific stop-loss caps the employer's liability on any single claim, typically at $250,000 to $1,000,000 per occurrence. Claims exceeding this threshold are paid by the excess carrier.
• Aggregate stop-loss caps the employer's total annual WC liability. If total claims in a year exceed the aggregate threshold, the excess carrier pays the overage.

Request a certificate showing the excess/stop-loss coverage. This provides assurance that even a catastrophic claim (a fatality or permanent total disability) will not exhaust the employer's financial resources.

The ACORD 25 and Self-Insured Employers

The standard ACORD 25 Certificate of Liability Insurance was designed for insured employers. The Workers' Compensation section expects a carrier name, policy number, and the standard WC/EL limits. Self-insured employers do not fit neatly into this format.

How Self-Insurance Appears on the ACORD 25

Brokers and TPAs handle self-insurance on the ACORD 25 in several ways:

Option 1: "Self-Insured" in the carrier column. The WC section lists "Self-Insured" or "Qualified Self-Insured" as the insurer. The policy number field shows the state self-insurance certificate number. The limits field may show "Statutory" (because the employer is still obligated to pay statutory benefits) or may be left blank.

Option 2: Description of Operations notation. The WC section is left blank, and the description of operations field includes a statement: "Employer is qualified self-insured for Workers' Compensation in [State] — Certificate #[number]."

Option 3: Separate self-insurance certificate. Some employers provide the state-issued Certificate of Self-Insurance as a standalone document rather than attempting to fit it onto the ACORD 25. This is actually the cleanest approach because the ACORD 25 format does not properly accommodate self-insurance.

What About Employers' Liability?

Self-insured WC programs include Employers' Liability (EL) coverage, but it is structured differently. Under a standard WC policy, EL limits are clearly stated ($500,000/$500,000/$500,000 or $1,000,000/$1,000,000/$1,000,000). Under self-insurance, the employer's EL exposure is covered by their self-insured retention and their excess/stop-loss policy.

Request confirmation of EL limits from the vendor's TPA or excess carrier. The excess policy should specify EL limits that meet your requirements.

Third-Party Administrators (TPAs)

Self-insured employers rarely manage WC claims in-house. Instead, they engage a Third-Party Administrator (TPA) to handle claims adjudication, medical management, return-to-work coordination, and regulatory reporting.

Why TPAs Matter for COI Compliance

The TPA is your operational contact for the self-insured vendor's WC program. When you need:

• Confirmation of self-insured status — the TPA can provide documentation
• Waiver of subrogation — the self-insured employer (not a carrier) grants the waiver, but the TPA facilitates the paperwork
• Evidence of coverage for a specific project — the TPA can issue a letter confirming coverage
• Claims information after an incident — the TPA manages the claim

Common TPAs

Major TPAs handling self-insured WC programs include Sedgwick, Gallagher Bassett, Broadspire (Crawford & Company), Helmsman Management Services (a Liberty Mutual company), and ESIS (a Chubb company). If the vendor names one of these TPAs, it is a strong indicator that their self-insured program is legitimate and professionally managed.

Waiver of Subrogation for Self-Insured Employers

Standard COI requirements include a waiver of subrogation on the WC policy. For insured employers, this is an endorsement added to the WC policy by the carrier. For self-insured employers, there is no carrier to add an endorsement.

Instead, the self-insured employer provides the waiver directly through a contractual agreement. The vendor contract should include language requiring the vendor to waive their right of subrogation against you for workers' compensation claims. Since the vendor is paying claims directly (not through a carrier), the vendor has the authority to waive subrogation without needing carrier approval.

Request a written waiver of subrogation from the vendor, signed by an authorized officer. The waiver should specifically reference workers' compensation claims arising from work performed under your contract.

Multi-State Self-Insurance

Large employers operating in multiple states face additional complexity. Self-insurance approval is granted on a state-by-state basis. An employer who is self-insured in California may not be self-insured in Nevada. For employers operating in states where they do not have self-insurance approval, they must purchase a standard WC policy.

When verifying a multi-state vendor's WC compliance:

1. Determine which states the vendor's employees will work in under your contract
2. Verify self-insured status in each of those states
3. For states where the vendor is not self-insured, require a standard WC certificate with the appropriate carrier and limits
4. Maintain records showing which states are self-insured and which are traditionally insured

This creates a split compliance file — part self-insurance documentation, part traditional COI — that must be tracked and renewed for each applicable state.

Red Flags

Watch for these indicators that a vendor's claimed self-insured status may not be legitimate:

• No state certificate number. Every approved self-insured employer has a certificate number from the state. If the vendor cannot produce one, they may not be approved.
• Small employer size. Self-insurance is typically for large employers (500+ employees). A ten-person subcontractor claiming to be self-insured for WC is almost certainly either confused or non-compliant.
• No TPA or excess coverage. Legitimate self-insured programs have both. An employer who claims to be self-insured but has no TPA and no excess coverage may simply be uninsured and using "self-insured" as a euphemism.
• State verification fails. If the state workers' compensation authority has no record of the employer as an approved self-insured entity, the claim is invalid.

Self-insured workers' compensation is a legitimate and well-regulated alternative to traditional insurance. Verifying it requires different tools than verifying a standard WC certificate, but the underlying principle is the same: confirm that the vendor has the financial resources and legal authorization to meet their workers' compensation obligations to their employees.
