Q: What’s California State Disability Insurance (CASDI)?

CASDI, or CA-SDI, stands for California State Disability Insurance. 

Employees who can’t work because of a temporary non-work-related illness or injury can apply for short-term disability insurance through CASDI. 

The program allows California employees to collect weekly, tax-free benefits until they’re ready to return to work or until their benefits expire (for up to one year). The benefits are equal to around 60-70% of an employee’s average gross income in a quarter. 

Employees pay for the program through a state income tax that’s withheld from each paycheck. (Note that many small business payroll providers can automatically handle CASDI deductions for employers.)

The amount withheld will appear on an employee’s pay stub as “CASDI-E,” which stands for “California State Disability Income tax; Employee contribution.” It’s usually listed in the deductions section of a pay stub.

Who pays for CASDI?

Employees pay for CASDI—not employers.

As a California employer, you deduct the CASDI tax (as well as California Paid Family Leave) from each employee’s check each pay period. If you use an online payroll service, it can usually take care of the deduction for you. 

When employees fill out information for CASDI on their W-2 form, they must enter the dollar amount withheld in Box 14. This allows them to claim it as an itemized deduction for state and local income taxes. The amount will be subtracted from their adjusted gross income to lower their total tax bill. 

What is the CASDI rate for 2020?

The employee contribution rate in 2020 will remain at 1.0%. The maximum weekly benefit amount is expected to increase to $1,327, up from $1,252 in 2019.

In 2020, you’ll likely need to withhold the CASDI tax from wages up to $125,462, which is up from $118,371 in 2019.

Who is eligible for CASDI?

No matter their citizenship or immigration status, employees who are unable to work due to a non-work-related illness, injury, or pregnancy may be eligible for short-term disability insurance under CASDI. 

To qualify, an employee must:

  • Be unable to perform their regular work for at least eight consecutive days
  • Have earned at least $300 in wages during the previous 12 months, from which CASDI was withheld through payroll deductions
  • Have lost wages due to their disability
  • Be employed or looking for work when they apply
  • Be under the care of a licensed physician, practitioner, or religious practitioner during the first eight days of their disability
  • Make the claim within 49 days of the date the disability started and no earlier than nine days 
  • Have their physician or practitioner complete a medical certification of the disability.

Employees can apply through the SDI Online portal on the Employment Development Department (EDD) State of California website by creating an EDD login. 

Are independent contractors eligible for CASDI?

If you or your worker is self-employed or work as an independent contractor, you have the option of paying into the EDD’s Disability Insurance Elective Coverage (DIEC) program. 

This program provides disability insurance and paid family leave coverage when you aren’t required to pay into state disability insurance (SDI). You pay for coverage through quarterly premiums. 

For more information, visit the DIEC Forms and Publications page.

What are my CASDI responsibilities as an employer?

As an employer, you don’t pay for CASDI. However, you do need to withhold and send employee contributions to the EDD. 

You’ll also need to give employees certain information about the laws and regulations related to employment, benefits, and working conditions. This includes posting and providing the following: 

  • Notice to Employees: Unemployment Insurance/Disability Insurance/Paid Family Leave (DE 1857A): This poster lists an employee’s right to claim UI, DI, and PFL benefits. If your employees aren’t covered by UI, you need to post the Notice to Employees (DE 1858).
  • Disability Insurance Provisions (DE 2515): Give this brochure to new hires and anyone who asks for time off due to a non-work-related illness, injury, pregnancy, or childbirth.
  • Paid Family Leave Benefits (DE 2511): Give this brochure to new hires and anyone who asks for time off to bond with a new child or to care for a seriously ill family member.

You can order these free posters and brochures through the EDD’s Online Forms and Publications page or by calling 1-800-480-3287. Or you can download and print DI Forms and Publications and PFL Forms and Publications.

When an employee files a claim, you’ll need to respond to the following: 

  • Notice to Employer of Disability Insurance Claim Filed (DE 2503): You’ll receive this form after an employee files a DI claim. You must complete and return it to the EDD within two working days using either SDI Online or the paper form to verify the information on the employee’s claim.
  • Notice of Paid Family Leave (PFL) Claim Filed (DE 2503F): You’ll receive this form after an employee files a PFL claim. You need to complete and return the paper form to the EDD within two working days to verify the information on the employee’s claim.

If you have employees working in San Francisco: You may be required to supplement wages if an employee receives PFL benefits for bonding with a new child through birth, adoption, or foster care placement. 

Visit the EDD’s Paid Parental Leave Ordinance page for more information.

Can my company opt out of CASDI?

You can opt out of CASDI and create a private plan for voluntary disability insurance (known as a voluntary plan) if you meet certain requirements. 

A voluntary plan must:

  • Provide all the benefits of SDI
  • Include at least one benefit that is better than SDI
  • Not cost employees more than SDI
  • Be approved by a majority of your employees before it goes into effect

The primary benefit of a voluntary plan is that it lets you provide employees with better coverage at, potentially, no additional cost. If your employees have a low claim rate, you can use the extra contributions to provide higher benefits or to underwrite a lower contribution rate.  

To be approved, you need to post a security deposit with the EDD to guarantee that the voluntary plan meets all of the requirements.

For information on security deposits, reporting requirements, and disputing claims, read the Disability Insurance Employer’s Guide to Voluntary Plan Procedures (DE 2040).

Now you have a better understanding of CASDI and exactly what goes in—and out—of your employees’ paychecks.


  • Bonnie

    Is SDI required to be withheld from severance payments?

    • Gusto Editors

      Hi Bonnie — you’ll want to reach out to your state unemployment office for further clarification!

  • Frank Bringas

    I worked for an out of state company in 2019 that does business in California. I live and work in California an had California income tax withheld. I filed an SDI claim in February 2020. Upon seeing the notice of computation from EDD it showed there was no salary listed from the out of state company. I took a closer look at my last pay stuband it did nnot a a seperate witholding line for CASDI or for SDI. Does that mean I am not eligble to receive SDI payments based on those wages?

    • Gusto Editors

      Hi Frank, since guidance can vary by state and industry, we recommend reaching out to your state unemployment office.

  • Freda F.

    What if you are already receiving Ca. SDI before this Covid-19 epidemic became a pandemic, do you still received the government increase of pay?

  • Carlos Contreras

    can an employee opt out of this if their company doesn’t or is this something that is automatically taken out?

    • Gusto Editors

      Hi Carlos! According to the California EDD, your disability program is determined by your employment position and bargaining unit: https://www.edd.ca.gov/Disability/FAQ_DI_State_Employees.htm If you have any further questions, we recommend consulting a lawyer or HR expert for specific guidance.

  • Ronald R.

    Is this automatically calculated and deducted from California wages when using Gusto? Or does it have to be set up…?

    • Gusto Editors

      Hi Ronald! As long as your work address is listed in California, Gusto will automatically deduct (it’s a 1% tax). We will need your CA EDD number in order to remit to CA.

  • Rachel S

    I believe this post incorrectly lists the 2020 CA SDI rate. It is 1% and unchanged from 2019.

    • Gusto Editors

      Hi Rachel — great catch! The 2020 contribution rate was previously forecasted to increase to 1.1% in 2020 but it’s remained the same. We’ve updated the article to reflect this.
