What is CASDI?

CASDI stands for California State Disability Insurance, which is a compulsory payroll tax deduction for employees in California. It funds the temporary wage replacement for workers who are unable to work due to non-work-related illness or injury.

At CASDI, people can earn about 60-70% of their average quarterly gross earnings. Once people taking CASDI return to work, their benefit bills stop, and they begin paying into the program once again with the same old pay cuts.

What is CASDI on W2?

It is listed on Box 14 and is generally not deducted on federal tax returns, but it can be on state returns.

Who pays for CASDI?

CASDI is largely funded by employees, not by employers. Contributions are mechanically deducted from the worker’s paycheck through payroll taxes, which appear to be CASDI on their W-2 form. These funds go into California’s disability insurance software, which presents benefits such as short-term disability and paid family leave. Employers are responsible for withholding taxes and remitting them to the state, but they often don’t contribute their cash toward CASDI.

Who is eligible for CASDI?

• Paid into SDI: Your paycheck must have SDI deductions, and you must have earned at least $300 in wages during your base period. 
• Unable to work due to disability: This includes illness, injury, surgery, pregnancy, or childbirth.
• Have lost wages because of disability: CASDI only applies if your condition actually reduces your income.
• Your disability lasts 8 days: Short-term conditions under a week generally don’t qualify.

How can I file a CASDI claim, and how long does it take to receive benefits?

You will need to collect the following information to apply online:

• Identity documents and Social Security number
• Wages you expect to be paid by your employer while you’re not working
• Employer information
• Physician information

Once you finish your online application, you have to request that your doctor send a medical certificate to verify your disability. As soon as the EDD receives your application and doctor’s certificate, they will start to work on your claim. The EDD will send you a packet of documents to review by mail within two weeks.

If you find any inaccuracies in your personal details on your claim form, you must inform them immediately. If your application is granted, you will receive your first benefit payment approximately two weeks after the date that you applied. You should remember that every new claim has a seven-day unpaid waiting period.

Thus, even if the program runs for several days, only after your eighth day on leave will you receive payments.
