California SDI Tax: What That Deduction on Your Paycheck Actually Pays For

Every California paycheck includes a line item labeled "CA SDI" that most workers ignore until the day they actually need it. A state law that kicked in at the start of 2024 changed the economics of that deduction significantly, eliminating the annual wage cap and raising costs for higher earners. Whether you've been paying it for years or just got your first California paycheck, here's what the deduction covers and what you're entitled to collect.

What SDI Is and What It Covers
California's State Disability Insurance program is administered by the Employment Development Department and funded entirely through employee payroll withholding. Your employer doesn't contribute to it. The money you pay in supports two distinct benefit programs.
The first is Disability Insurance, which replaces a portion of your wages when you can't work because of a non-work-related illness, injury, or pregnancy-related condition. (On-the-job injuries are a separate matter handled through workers' compensation.) The second is Paid Family Leave, which provides partial wage replacement when you take time off to bond with a new child, care for a seriously ill family member, or assist a family member whose spouse has been deployed for military service.
How Much Comes Out of Your Paycheck
EDD sets the SDI contribution rate each January, expressed as a percentage of gross wages. For 2024, that rate was 1.1%. Check edd.ca.gov for the rate currently in effect, since the figure adjusts annually and any specific number you've seen cited elsewhere may be out of date.
The structural change that drew the most attention came from Senate Bill 951, signed by Gov. Gavin Newsom in 2022 and effective January 1, 2024. Before that date, SDI withholding stopped once a worker's annual earnings hit a taxable wage ceiling, which sat at roughly $153,164 for calendar year 2023. The new law removed that cap entirely. Every dollar of wages is now subject to SDI withholding, with no annual cutoff. For someone earning $200,000 or more, that translated to a real and noticeable increase in annual payroll costs starting in 2024.

How to File a Claim and What You'll Receive
If you need benefits, EDD calculates your weekly payment based on a base period, typically the 12 months that ended roughly five to six months before your claim date. California uses a tiered formula, so lower-wage workers replace a higher share of their earnings. EDD publishes current benefit percentages and maximum weekly amounts at edd.ca.gov/disability, and those figures update periodically, so verify them before making any financial plans around a potential claim.
Disability Insurance benefits can last up to 52 weeks for a single qualifying period.
