The California State Disability Insurance (SDI) tax is a mandatory payroll deduction funding temporary disability benefits for eligible workers. Employers withhold this tax from employees' wages and remit it to the state.
California's SDI program provides partial wage replacement to workers who need time off due to non-work-related illness, injury, pregnancy, or to bond with a new child. The tax rate and maximum contributions adjust annually based on statewide wages.
Employers withhold SDI tax from employees' wages using a percentage-based withholding method. As of 2023, the withholding rate is 1.2% of taxable wages, capped at the first $165,600 of annual earnings. This generates approximately $12 billion annually for the state's disability insurance fund.
| Benefit Type | Duration | Maximum Weekly Benefit (2023) |
|---|---|---|
| Disability Insurance | Up to 52 weeks | $1,591.41 |
| Paid Family Leave | Up to 8 weeks | $1,591.41 |
Many people confuse SDI with workers' compensation, which covers work-related injuries. Unlike workers' comp, SDI applies to non-job-related conditions and doesn't require employer fault. Another misunderstanding is that SDI benefits are fixed amounts - they actually scale with income.
For example, a worker earning $3,000 weekly would receive about $2,100 monthly during disability leave, while someone earning $1,500 weekly would get around $1,050 monthly. These calculations account for the 70% replacement rate and other factors.
Only employees pay the SDI tax - employers do not contribute. This differs from federal programs like Social Security, where both employers and employees contribute. The tax appears as a separate line item on pay stubs labeled "CA SDI" or "State Disability Insurance."
Self-employed individuals can opt into the program by filing Form DE 145 with the California Employment Development Department. They pay the full 1.2% rate on their net earnings up to the annual limit.
The SDI tax ensures workers have financial protection during unexpected leaves. Without it, many employees would face significant income loss during periods of disability or family leave. The program's funding structure balances affordability with adequate benefit levels.
For context, California's SDI program is one of the most complete in the nation. According to the California Employment Development Department, it serves over 1.5 million claimants annually. This demonstrates both the program's scale and its importance to working Californians.
