What you pay into California SDI and how the rate is set

California State Disability Insurance (SDI) is funded by a payroll tax on employees only — your employer does not contribute. The tax rate changes each year based on how much money the SDI fund paid out the previous year and how much it has in reserve. For 2024, the employee tax rate is 1.0% of wages, with a maximum taxable wage base of $153,164 per year. This means the most you pay in SDI tax in a single year is $1,531.64.

The rate is set by the California Department of Employment Development (EDD) and announced in October for the following calendar year. The EDD calculates the rate by looking at claims paid, the fund balance, and projected future claims. If the fund runs low, the rate goes up. If the fund has a healthy reserve, the rate may stay the same or decrease. You will see the SDI tax deducted from your paycheck under the line item "SDI" or sometimes "DI".

Not all workers pay SDI tax. Federal employees, railroad workers covered by federal railroad retirement, and certain other groups are exempt. If you work for a private employer or most public employers in California, you almost certainly pay it.

Key Takeaways

  • California SDI tax is deducted from your paycheck only — your employer does not pay into the system.
  • The tax rate changes yearly and is set by the EDD based on fund reserves and claims history, not by a fixed law.
  • For 2024, the rate is 1.0% of wages up to a maximum taxable wage of $153,164 per year.
  • The rate is announced in October and takes effect January 1 of the following year.
  • Federal employees, railroad workers, and a small number of other groups do not pay California SDI tax.

How the rate has changed in recent years

The SDI tax rate has fluctuated over the past decade as the fund balance shifted. In 2020 and 2021, during the pandemic, claims surged and the rate increased. In 2022, the rate was 1.2%. By 2023, it had dropped to 1.1%, and in 2024 it fell further to 1.0%. These changes reflect both the number of claims paid and the fund's ability to cover future obligations.

The maximum taxable wage base also changes annually. It is tied to the state average wage index and increases most years. In 2023, it was $153,164, and it remained at that level for 2024. Workers earning above the maximum wage base still pay the tax, but only on the first $153,164 of their annual income.

Where your SDI tax money goes

Your SDI tax funds the State Disability Insurance program, which pays partial wage replacement to workers who cannot work due to a non-work-related illness or injury. It also funds Paid Family Leave (PFL), which allows workers to take time off to bond with a newborn, care for a family member, or handle a may have access to exigency related to military service. Both programs are administered by the EDD.

When you file a claim for SDI or PFL, the benefits you receive come from this fund. The EDD uses actuarial analysis to set the rate high enough to cover expected claims while maintaining a reserve for unexpected surges in demand, such as what happened during the COVID-19 pandemic.

How to verify your SDI tax deductions

You can check your SDI tax payments on your pay stub. Look for a line labeled "SDI" or "DI" under deductions. The amount should be 1.0% of your gross wages (or your total wages up to the maximum taxable wage base if you earn more than $153,164 per year).

At the end of the year, your employer reports your total SDI tax paid on your W-2 form in Box 4, labeled "Social Security tax withheld." This is separate from federal Social Security tax. You can also create an account on the EDD website to view your wage and tax records, though SDI tax records are not displayed there in the same way federal tax records appear on the IRS website.

If you believe your SDI tax has been calculated incorrectly, contact your employer's payroll department first. If the error persists, you can file a wage claim with the EDD, though this process is separate from disputing the tax rate itself.

What happens if you do not pay SDI tax

If you are a covered employee and your employer does not deduct SDI tax from your paycheck, your employer is breaking state law. You can report this to the EDD's Labor Commissioner's Office. However, not paying SDI tax does not mean you are ineligible for benefits — the EDD will look at your actual wage records to determine what you owed and what you are may have access to to receive.

If you are self-employed, you do not pay SDI tax and you are not covered by SDI. Self-employed workers can purchase Voluntary Disability Insurance (VDI) through the EDD if they want coverage, though this is a separate program with its own rules and costs.

Self-employed workers and voluntary coverage

Self-employed individuals in California do not pay the standard SDI tax and are not automatically covered by SDI. However, the EDD offers Voluntary Disability Insurance (VDI), which allows self-employed workers to purchase coverage. The cost and terms of VDI differ from the standard SDI program, and enrollment is limited to certain periods of the year.

If you are self-employed and interested in VDI, you must explore during an open enrollment period, which typically occurs in October and November. You can contact the EDD directly or visit their website to learn about current rates and enrollment requirements for VDI.

Frequently Asked Questions

Why does the SDI tax rate change every year?

The EDD adjusts the rate based on how much money the SDI fund paid out, how much it has in reserve, and projected future claims. If claims are high and reserves are low, the rate increases. If reserves are healthy, the rate may decrease or stay flat.

Is SDI tax the same as Social Security tax?

No. Social Security tax (6.2% of wages) and SDI tax (1.0% for 2024) are separate deductions. Social Security is a federal program; SDI is a California state program. Both appear on your pay stub as distinct line items.

Can I get a refund of SDI tax I paid?

No. SDI tax is not refundable. It funds the insurance pool that pays benefits to workers who become disabled or take paid family leave. If you never file a claim, you do not receive a refund of your contributions.

What if I work in California but live in another state?

If your employer is in California and you are a covered employee, you pay California SDI tax regardless of where you live. The tax is based on where your wages are earned, not where you reside.

Do independent contractors pay SDI tax?

No. Independent contractors are not covered by SDI and do not pay the tax. Only employees of covered employers pay SDI tax. If you are unsure whether you are classified as an employee or contractor, contact the EDD or your employer's payroll department.
