California Court Upholds Workers’ Compensation Policy Cancellation After Employer Ignored Payroll Audit Requests

A California employer’s failure to respond to repeated payroll-audit requests allowed its insurance carrier to cancel the employer’s workers’ compensation policy, leaving the employer without that coverage when an employee was later injured.

That is the central holding of Employers Preferred Insurance Co. v. Workers’ Compensation Appeals Board, No. C104263, a Third District Court of Appeal decision certified for publication on August 6, 2026.

The decision offers an important warning to California employers: Ignoring an insurer’s payroll-audit requests can jeopardize active workers’ compensation coverage. For injured workers, the case also illustrates why identifying every potentially responsible employer, insurer, and source of benefits can become critical when coverage is disputed.

Case Background: Ignored Payroll Audits and Policy Cancellation

Employers Preferred Insurance Company issued workers’ compensation policies to Purchase Green Artificial Grass.

After one policy period ended, the insurer repeatedly requested payroll records so that it could perform a final premium audit. The employer did not respond to letters and emails sent over more than three months. The insurer then sent a certified letter and issued a notice cancelling the employer’s renewal policy.

Approximately five months after the cancellation became effective, one of the employer’s employees suffered an injury and filed a workers’ compensation claim. The insurer denied the claim because, according to the insurer, the policy had already been cancelled.

The coverage dispute proceeded to arbitration within the workers’ compensation system. The arbitrator concluded that the cancellation was ineffective because neither the policy nor the Insurance Code precisely defined what conduct constituted a “failure to permit” a payroll audit. The Workers’ Compensation Appeals Board adopted that reasoning and denied the insurer’s petition for reconsideration.

The insurer then sought review in the Court of Appeal.

The Court of Appeal’s Decision

The Court of Appeal annulled the WCAB’s order and remanded the case for further proceedings.

Under California Insurance Code section 676.8, an insurer may cancel a workers’ compensation policy when the policyholder fails to report payroll or permit a payroll audit as required by the policy. The policy at issue required the employer to provide the records necessary for the insurer to calculate the final premium.

Although the policy did not expressly define every circumstance constituting a failure to permit an audit, the court held that the employer’s complete lack of response satisfied that standard.

The insurer had:

• Sent multiple requests for payroll information;
• Allowed more than 90 days for a response;
• Sent a certified notice concerning the employer’s failure to provide access;
• Provided advance written notice of cancellation; and
• Waited more than 30 days after delivery of the certified letter before the cancellation took effect.

The employer neither supplied the requested records nor offered a compelling business reason for failing to do so.

The court rejected the WCAB’s conclusion that something more was required. Contract terms, the court explained, must be interpreted reasonably and in context. An employer cannot avoid the consequences of a payroll-audit provision merely because the policy does not separately define every word used in its cancellation clause.

Does Silence Equal a Refusal to Permit a Payroll Audit?

The employer argued that it never affirmatively refused to cooperate. Its owner testified that he did not remember receiving the insurer’s communications.

That did not change the result.

The policy imposed an affirmative duty on the employer to provide payroll records when requested. The court therefore concluded that the employer’s intent was irrelevant. What mattered was that the employer failed to provide the records necessary to complete the audit.

In practical terms, silence can amount to noncompliance. An insurer need not obtain an express statement that the employer refuses an audit before acting under a properly drafted cancellation provision.

Were Automated Written Cancellation Notices Sufficient?

The employer also argued that the insurer should have made personal contact by telephone or visited the business before cancelling the policy.

The court rejected that argument because neither the policy nor the applicable statutory scheme required personal outreach. The insurer’s written and electronic notices complied with the parties’ agreement and the governing cancellation rules.

The decision reinforces the importance of monitoring all addresses and email accounts associated with an insurance policy. Missing, overlooking, or failing to remember a notice may not excuse noncompliance.

A Later Billing Error Did Not Restore Coverage

Finally, the employer relied on a later letter that mistakenly described the policy period as extending beyond the cancellation date.

The court found that equitable estoppel did not apply. The letter was sent after the employee’s injury, so the employer could not have relied on it when the injury occurred. Paying the amount shown in that later correspondence also did not retroactively restore coverage for the date of injury.

What Does the Decision Mean for California Employers?

California employers should treat workers’ compensation payroll-audit requests as urgent compliance matters.

An employer receiving an audit request should promptly:

• Confirm that the insurer has the correct mailing and email addresses;
• Preserve and produce the requested payroll records;
• Document all communications with the insurer;
• Explain any legitimate reason for a delay in writing; and
• Obtain immediate advice if the insurer threatens cancellation.

Allowing a workers’ compensation policy to lapse or be cancelled can expose an employer to substantial direct liability, penalties, and other consequences.

What Does the Decision Mean for Injured Workers?

The decision did not decide whether the injured employee ultimately had another route to benefits. It resolved the dispute over whether this particular insurer had effectively cancelled its policy.

When an insurer denies a claim based on cancellation or lack of coverage, the denial does not necessarily end the inquiry. Important questions may remain, including:

• Whether the cancellation complied with the policy and California law;
• Whether another insurer provided coverage;
• Whether the employer was legally uninsured;
• Whether the Uninsured Employers Benefits Trust Fund may be implicated; and
• Whether additional parties should be joined in the workers’ compensation proceeding.

Coverage disputes can significantly complicate an otherwise valid workplace-injury claim. Prompt investigation is essential because the employer’s records, insurance notices, policy documents, and coverage history may determine who is responsible for benefits.

The Bottom Line

Employers Preferred confirms that repeated nonresponse to payroll-audit requests can constitute a failure to permit an audit and support cancellation of a California workers’ compensation policy.

For employers, the lesson is straightforward: Do not ignore an insurer’s audit communications. For injured workers, a coverage denial requires careful investigation—it should not automatically be treated as the final word.
