California SDI is a payroll tax that funds disability and family leave benefits

California State Disability Insurance (SDI) is a mandatory payroll deduction in California. Money withheld from your paycheck funds two programs: Disability Insurance, which pays you if you cannot work due to illness or injury, and Paid Family Leave, which pays you to care for a newborn, newly adopted child, or seriously ill family member.

The tax appears on your pay stub as "SDI" or "DI" and is deducted automatically if you work in California. You do not choose whether to pay it — it is required by state law. The amount withheld is a percentage of your gross wages, up to a maximum annual contribution that changes each year.

SDI is separate from federal income tax, Social Security, and Medicare. It is also separate from California state income tax, though both appear on the same pay stub. Unlike unemployment insurance, which your employer pays entirely, SDI is funded by employee contributions only — your employer does not contribute to this program.

Key Takeaways

  • SDI is a California payroll tax deducted from your wages to fund disability and family leave benefits you may use later.
  • The tax rate and maximum annual contribution change each year; check your pay stub or the California Employment Development Department (EDD) website for the current amount.
  • You are covered automatically if you work in California and earn wages subject to SDI tax — you do not need to register or take any action.
  • SDI benefits replace a portion of your income if you are unable to work due to disability or need to take family leave, but the benefit amount is less than your full salary.

How much SDI tax comes out of your paycheck

The SDI tax rate is set by California each year and applies to wages up to a maximum amount. For 2024, the rate is 1.0 percent of gross wages, with a maximum annual contribution cap. This means if you earn $50,000 in a year, you pay 1.0 percent of that amount; if you earn $200,000, you still pay only on the capped maximum, not on all $200,000.

The exact rate and cap change annually. Your employer is required to calculate and withhold the correct amount based on the current year's figures. If you work multiple jobs in California, each employer withholds SDI separately, and you may pay more than the cap across all jobs combined — you would then claim the overpayment when you file your California tax return.

You can find the current year's rate and wage base on the California Employment Development Department website or ask your payroll department. Your pay stub should also show the SDI amount withheld each pay period.

Who pays SDI tax and who is exempt

Most employees in California pay SDI tax. However, certain workers are exempt. Federal employees, railroad employees covered by the federal Railroad Retirement Act, and some other groups do not pay California SDI because they are covered by different insurance systems.

Self-employed people do not pay SDI tax automatically, but they may choose to pay into the system to gain coverage. If you are self-employed and want SDI benefits, you must register with the California Employment Development Department and pay both the employee and employer portions.

Workers in other states who are temporarily working in California may also be exempt if their home state has an agreement with California. If you are unsure whether you are exempt, contact the EDD or ask your payroll department.

What SDI benefits cover and how much they pay

SDI benefits replace part of your income during two situations: when you cannot work due to a non-work-related illness or injury (Disability Insurance), and when you need to take time off to care for a newborn, newly adopted child, or a family member with a serious health condition (Paid Family Leave).

The benefit amount is calculated as a percentage of your average weekly wage, up to a maximum weekly amount set by the state each year. The benefit replaces roughly 55 to 60 percent of your wages, not your full salary. Benefits typically last up to 4 weeks for family leave and up to 26 weeks for disability, though the exact duration depends on your situation.

You must meet waiting periods and other requirements to receive benefits. For disability, you usually cannot receive benefits for the first seven days you are unable to work. For family leave, you must have worked for your employer for at least 12 months and worked at least 1,250 hours in the past 12 months.

How to file an SDI claim when you need benefits

To file an SDI claim, you contact the California Employment Development Department, not your employer. You can file online through the EDD website, by phone, or by mail. You will need your Social Security number, driver's license or ID number, and information about your employer and the reason you cannot work.

The EDD will review your claim and determine whether you meet the requirements. Processing typically takes two to three weeks. During this time, you will not receive benefits. Once approved, the EDD sends payments by debit card or direct deposit, depending on how you set up your account.

You must report your claim status to the EDD regularly, usually weekly or every two weeks depending on the type of benefit. If you return to work before your benefits end, you must notify the EDD when ready.

SDI tax versus state income tax and other deductions

SDI is one of several deductions on your California paycheck. State income tax is separate — it is withheld based on your W-4 form and your income level. Federal income tax, Social Security, and Medicare are also separate deductions. Each one funds a different program and is calculated differently.

Unlike state income tax, which you may owe more of or receive a refund for when you file your return, SDI is a fixed contribution that does not change at tax time. You pay it every pay period, and it goes directly into the SDI fund. You do not claim SDI on your state income tax return unless you overpaid across multiple jobs.

If you are self-employed, you may pay both SDI and self-employment tax, which funds Social Security and Medicare. These are also separate from state and federal income tax. Understanding which deductions fund which programs helps you know what to expect on your pay stub and what benefits you may be may have access to to.

What happens if you move out of California or change jobs

If you move to another state, you stop paying California SDI on wages earned in that state. However, if you return to California later, your SDI account remains active and your previous contributions count toward your benefits. You do not lose your SDI coverage by moving.

If you change jobs within California, you continue paying SDI to each new employer. Your SDI account follows you — it is tied to your Social Security number, not to a specific employer. If you work multiple jobs in California at the same time, each employer withholds SDI separately.

If you become unemployed, you may be able to file for Unemployment Insurance through the EDD. This is a different program from SDI, though both are administered by the same agency. You can receive both benefits in some situations, but the rules are specific about how they interact.

Frequently Asked Questions

Can I opt out of paying SDI tax?

No. SDI is mandatory for most California employees. You cannot choose not to pay it. If you believe you are exempt, contact the California Employment Development Department with documentation of your exemption status.

What if I paid too much SDI across multiple jobs?

If you worked multiple jobs in California and your total SDI contributions exceeded the annual maximum, you can claim the overpayment on your California tax return. You will receive a refund of the excess amount when you file.

Do I get SDI benefits automatically after I pay the tax?

No. Paying SDI tax makes you covered, but you must file a claim with the EDD when you need benefits. You must also meet specific requirements for the type of benefit you are seeking, such as having worked a certain number of hours or having a may have access to reason for leave.

How long does it take to receive my first SDI payment?

The EDD typically takes two to three weeks to process and approve your claim. Once approved, your first payment arrives within one to two weeks, depending on whether you chose direct deposit or a debit card.

Can I receive SDI benefits if I was laid off?

SDI does not cover job loss. If you were laid off, you may be able to file for Unemployment Insurance instead. If you cannot work due to an illness or injury that occurred while you were employed, you may be able to file for SDI disability benefits regardless of whether you were later laid off.
