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

State Disability Insurance (SDI) tax is a deduction from your California paycheck that pays into a state insurance fund. If you become unable to work due to a non-work injury or illness, or if you need to take time off to care for a family member, SDI can replace part of your lost wages. The tax rate and wage base change each year, and your employer deducts it automatically — you do not have a choice about whether to pay it.

California is one of only a few states that runs this program. The money does not go into a general state fund; it goes into a dedicated account managed by the California Employment Development Department (EDD). When you file a claim, the EDD pays benefits from that account, not from general tax revenue.

Key Takeaways

  • SDI tax is deducted from your paycheck by your employer and funds two separate benefit programs: Disability Insurance (DI) and Paid Family Leave (PFL).
  • The tax rate and maximum wage base change yearly; for 2024, the employee rate is 1.0% of wages up to a state-set maximum.
  • You can only claim SDI benefits if you have paid into the system through payroll deductions in the past 12 months.
  • Benefits replace roughly 55% to 60% of your regular wages, up to a maximum amount that changes each year.
  • You file claims through the EDD website or by phone, and the EDD determines whether your situation meets the program's rules.

How much SDI tax comes out of your paycheck

The amount deducted depends on two things: the current tax rate and the wage base cap. The tax rate is set by the state each year based on how much money is in the SDI fund. The wage base is the maximum amount of your annual earnings that is subject to the tax.

For 2024, the employee contribution rate is 1.0% of your wages, but only up to a maximum annual wage base of $153,164. This means if you earn $153,164 or more in a year, you pay SDI tax only on the first $153,164 of your income. If you earn less, you pay 1.0% of what you actually earn. These numbers change each January, so check the EDD website if you need the current year's figures.

Your employer is responsible for withholding this amount from your paycheck. You will see it listed on your pay stub as "SDI" or "State Disability Insurance." Some employers also contribute to the fund, but that is separate from what comes out of your check.

What SDI tax actually funds: two separate programs

Your SDI deduction pays for two different benefit programs. The first is Disability Insurance (DI), which covers you if you cannot work because of an illness or injury that is not job-related. The second is Paid Family Leave (PFL), which covers you if you need to take time off to bond with a new child, care for a seriously ill family member, or handle a military family member's may have access to exigency.

Both programs are funded by the same payroll tax. The EDD splits the money between them based on projected claims. You do not choose which program your tax goes toward — the state allocates it. However, when you file a claim, you will file for one program or the other depending on your situation.

The benefit amount and duration differ between the two programs. DI typically pays for up to 52 weeks, while PFL typically pays for up to 8 weeks in a 12-month period. Both programs replace a percentage of your regular wages, not your full salary.

Who pays SDI tax and who does not

If you are a California employee and your employer withholds income tax from your paycheck, you almost certainly pay SDI tax. This includes full-time, part-time, and temporary workers. The only common exceptions are federal employees, railroad employees covered by federal railroad retirement, and certain other groups covered by separate insurance systems.

Self-employed people in California can choose to pay into SDI voluntarily, but it is not required. If you are self-employed and want coverage, you must register with the EDD and pay both the employee and employer portions of the tax. Gig workers and independent contractors are generally not covered unless they register voluntarily.

If you work for multiple employers in California, each one withholds SDI tax based on your wages with them. You pay tax on all your California wages up to the annual wage base, even if you work for several companies.

When you can claim SDI benefits

To claim SDI benefits, you must meet several conditions. First, you must have paid SDI tax during a base period — typically the 12 months before you file your claim. Second, your reason for not working must fall within the program's rules: a non-work-related illness or injury for DI, or a may have access to family or military reason for PFL. Third, you must be unable or unavailable to work during the period you are claiming.

You cannot claim SDI for a work-related injury; that is covered by workers' compensation instead. You also cannot claim if you quit your job voluntarily, were fired for misconduct, or are on strike. The EDD reviews each claim to confirm you meet these conditions.

If you have not worked in California or have not paid SDI tax recently, you may not have a valid base period and could be denied. The EDD will tell you during the claim process whether you have enough wage history to proceed.

How to file an SDI claim

You file SDI claims through the EDD, either online at the EDD website or by phone. To start a claim online, you will need your Social Security number, driver's license or state ID number, and information about your employer and the reason you cannot work. The online system walks you through the questions and submits your claim when ready.

If you prefer to call, the EDD has a phone line for new claims. Wait times can be long, especially during high-volume periods. After you file, the EDD sends you a notice confirming receipt and telling you what happens next. You will also receive a information letter that says whether your claim was approved or denied and, if approved, how much you will receive each week.

Once approved, benefits are paid by debit card or direct deposit, usually within two weeks of your claim being filed. You must continue to report your status to the EDD while you are receiving benefits; the program requires regular check-ins to confirm you are still unable to work.

How much SDI benefits replace and how long they last

SDI benefits replace a portion of your regular wages, not your full paycheck. The replacement rate is roughly 55% to 60% of your average weekly wage, calculated from the highest quarter of your base period. There is a minimum weekly benefit amount and a maximum weekly benefit amount, both of which change each year.

For Disability Insurance (DI), you can receive benefits for up to 52 weeks within a 12-month period. For Paid Family Leave (PFL), you can receive benefits for up to 8 weeks within a 12-month period. Some people may have access to for both in the same year — for example, if you take family leave and then later become disabled — but the total weeks are limited.

The exact amount you receive depends on your wage history during the base period. The EDD calculates this automatically when you file your claim. If you disagree with the amount, you can request a reconsideration or appeal through the EDD.

Frequently Asked Questions

Can I get my SDI tax back if I do not use the benefits?

No. SDI tax is a mandatory payroll deduction in California, and you do not get a refund if you never claim benefits. The money stays in the state fund to pay other workers' claims. It functions like insurance: you pay into it whether or not you use it.

Does SDI tax count toward my Social Security?

No. SDI tax is separate from Social Security tax (FICA). Both are deducted from your paycheck, but they fund different programs. SDI does not add to your Social Security earnings record or affect your future Social Security benefits.

What happens to my SDI if I move out of California?

If you move out of California and stop working there, you stop paying SDI tax. However, if you have already filed a claim before moving, the EDD will continue to pay it as long as you meet the program's requirements. If you move and then become unable to work, you cannot file a new SDI claim unless you return to California employment.

Can my employer refuse to withhold SDI tax?

No. SDI withholding is required by California law for all covered employees. Your employer must deduct it from your paycheck. If your employer is not withholding SDI, you can report it to the EDD or the California Department of Industrial Relations.

Do I have to report SDI benefits as income on my taxes?

SDI benefits are not taxable income for federal or California state income tax purposes. You do not report them on your tax return, and they do not affect your tax liability. The EDD does not issue a 1099 or other tax form for SDI payments.
