California State Disability Insurance (CASDI)

California State Disability Insurance (CASDI) is a mandatory payroll program that provides partial wage replacement to employees who are temporarily unable to work due to non-work-related illness, injury, or pregnancy. For HR leaders in California, managing CASDI correctly is critical not just for compliance, but for protecting employee income security during vulnerable life events.

TL;DR

• California State Disability Insurance (CASDI) provides short-term wage replacement
• Funded entirely through employee payroll deductions
• Covers non-work-related illness, injury, pregnancy, and childbirth
• Managed by the Employment Development Department (EDD)
• Mandatory for most California employers and employees

What Is California State Disability Insurance (CASDI)?

California State Disability Insurance (CASDI) is a state-run insurance program that offers temporary income support to eligible employees who cannot perform their regular work duties due to a qualifying disability. Unlike workers' compensation, CASDI applies only to non-occupational conditions.

From an HR compliance perspective, CASDI is not optional. Employers are legally required to deduct CASDI contributions from employee wages and remit them to the state. Employees, in turn, gain access to short-term financial protection when health conditions interrupt their earning ability.

CASDI is part of California's broader State Disability Insurance (SDI) system, which also includes Paid Family Leave (PFL). Together, these programs form a foundational safety net for the state's workforce.

How Does CASDI Work?

The California State Disability Insurance (CASDI) program operates through payroll deductions and state-administered benefit payments.

Employee Payroll Contributions

CASDI is funded entirely by employees, not employers. A small percentage of an employee's wages up to a state-defined wage cap is withheld each pay period. HR teams must ensure accurate calculation and timely remittance to avoid penalties.

Benefit Payments

When an eligible employee files a claim and it is approved, CASDI pays a percentage of the employee's regular wages for a limited period. Payments are issued directly by the state, not the employer.

Duration of Benefits

Benefits are typically available for up to 52 weeks, depending on the nature and duration of the disability.

Pro Tip: Clear employee communication around CASDI deductions and benefits reduces payroll-related disputes and improves trust in HR processes.

What Does CASDI Cover?

California State Disability Insurance (CASDI) covers a wide range of temporary, non-work-related conditions.

Non-Work-Related Illness or Injury

If an employee cannot work due to a medical condition unrelated to their job such as surgery recovery or serious illness CASDI may provide income replacement.

Pregnancy and Childbirth

CASDI plays a major role in pregnancy-related leave, covering the period before and after childbirth when an employee is medically unable to work.

Mental Health Conditions

Certain mental health conditions, when medically certified, may also qualify for CASDI benefits.

However, CASDI does not cover:

• Work-related injuries (covered under workers' compensation)
• Long-term or permanent disabilities
• Voluntary time off without medical certification

Who Is Eligible for California State Disability Insurance?

Eligibility for California State Disability Insurance (CASDI) depends on several factors:

• The employee must have earned sufficient wages during the base period
• The disability must be medically certified
• The employee must be unable to perform their regular work
• The claim must be filed within required timelines

Most private-sector employees in California are covered. Some public employees and specific job categories may be excluded or covered under alternative disability plans.

HR teams must accurately classify employees to ensure correct CASDI deductions and eligibility alignment.

CASDI vs Workers' Compensation

Understanding this distinction is critical for HR teams when guiding employees on which benefit to claim.

Employer Responsibilities Under CASDI

Although employers do not pay CASDI premiums, their administrative role is significant.

Payroll Accuracy

HR must calculate deductions correctly and reflect them clearly on payslips.

Timely Remittance

Contributions must be submitted to the state within prescribed timelines to avoid fines.

Employee Support

While claims are state-managed, HR often assists employees with forms, wage verification, and leave coordination.

Compliance Reporting

Accurate records are essential for audits and employee disputes.

Why CASDI Matters Strategically for HR Leaders

For HR and leadership teams, California State Disability Insurance (CASDI) is more than a statutory deduction. It reflects how well the organization supports employees during health-related disruptions.

Strong CASDI compliance:

• Protects employees from sudden income loss
• Reduces financial stress and improves recovery outcomes
• Strengthens employer credibility and trust
• Minimizes payroll and compliance risks

In competitive talent markets like California, statutory benefits handled well often influence employer reputation as much as voluntary perks.
