California State Disability Insurance is not taxable on your California state return

California State Disability Insurance (SDI) benefits are exempt from California state income tax. This means you do not report SDI payments as income on your California Form 540 or any state tax form. The California Department of Tax and Fee Administration treats SDI as a non-taxable social insurance benefit, similar to how the federal government treats SSDI.

However, the tax treatment of SDI differs sharply depending on whether you receive it alone or alongside other income. If you work part-time while collecting SDI, or if you have investment income, pension income, or other earnings, those other sources remain fully taxable to California. The SDI portion stays exempt—but your total tax bill may still be substantial.

The federal government also does not tax SDI, so you will not owe federal income tax on those payments either. This makes SDI one of the few income sources that escapes both state and federal taxation.

Key Takeaways

  • California SDI payments are completely exempt from California state income tax and do not appear on your state return.
  • The federal government also does not tax SDI, so you owe no federal income tax on those benefits.
  • If you earn wages, self-employment income, or other money while receiving SDI, only those other sources are taxable—the SDI itself remains tax-free.
  • You still must file a California return if your other income exceeds the filing threshold, even though SDI is not counted.

How SDI differs from SSDI on your tax forms

California SDI and federal SSDI are separate programs with separate tax rules, though both are exempt from taxation. SDI is a short-term, work-related disability program run by California's Employment Development Department (EDD). It replaces a portion of your wages if you cannot work due to illness or injury. SSDI is a federal program based on your work history and Social Security credits.

On your federal return, SSDI appears on Form SSA-1099, which you receive from Social Security. On your California return, SDI does not appear on any form at all—you straightforward do not report it. The EDD does not issue a 1099 for SDI because the state considers it non-taxable from the start.

If you receive both SSDI and SDI at the same time, neither is taxable. You will receive a Form SSA-1099 for the SSDI (which you may need to show your tax preparer, even though it is not taxable), but you will receive nothing for SDI. Both programs remain outside your taxable income.

What happens if you work while receiving SDI

SDI is designed for temporary disability, so you may return to work part-time or full-time while benefits are still being paid. Any wages you earn are fully taxable to both California and the federal government. The SDI portion of your income remains tax-free, but your W-2 wages are reported normally.

If you earn enough to owe California income tax, you must file a return and pay tax on your wages. The threshold for filing depends on your age and filing status—for example, in 2024 a single person under 65 must file if they earned more than $23,942 in gross income. Your SDI does not count toward that threshold, but your wages do.

Some people receiving SDI also collect unemployment insurance (UI) while waiting to return to work. UI is taxable in California, unlike SDI. If you receive both SDI and UI, only the UI is reported on your tax forms and is subject to tax.

Filing requirements when you have SDI and other income

You must file a California return if your total income from all sources (excluding SDI) exceeds the filing threshold for your age and status. This means you add up your wages, self-employment income, interest, dividends, capital gains, pensions, and other taxable sources—but you do not include SDI in that calculation.

Even if your SDI alone would have been enough to live on, if you earned $24,000 in wages during the year, you owe a return. The SDI is invisible to the filing requirement; only your other income matters.

If you are unsure whether you must file, the EDD website and the Franchise Tax Board website both offer filing requirement calculators. You can also contact a tax preparer or call the Franchise Tax Board's helpline. Filing when you are not required to does no harm, and many people file anyway to claim refundable credits like the Earned Income Tax Credit (EITC).

SDI and federal tax credits you may be able to claim

Because SDI is not taxable income, it does not reduce your may be able to access for federal tax credits based on income limits. If you receive SDI and have little or no other income, you may be able to claim the Earned Income Tax Credit (EITC) if you also have wages. The EITC is a refundable credit that can result in a refund even if you owe no tax.

You may also be able to claim the California Earned Income Tax Credit (CalEITC), which is California's version of the federal credit. Both credits are based on earned income (wages or self-employment income), not on SDI. If you have no earned income, you cannot claim either credit, even if SDI is your only source of support.

Other credits, such as the Child and Dependent Care Credit or the Child Tax Credit, are not affected by SDI income. Your SDI does not reduce your income for purposes of these credits, and it does not phase them out.

Reporting SDI on other government forms and programs

Although SDI is not taxable, some government programs and agencies do count it as income for purposes of determining your may be able to access for other benefits. For example, Medi-Cal (California's Medicaid program) counts SDI as income when deciding whether you meet the income limit. If you receive SDI and are explore for Medi-Cal, you will need to report the SDI amount.

Similarly, if you explore for CalFresh (food information), housing information, or other means-tested programs, SDI counts as income. The rules vary by program, and some programs have higher income limits than others. You should always disclose SDI when explore for any benefit program, even though it is not taxable.

For Social Security purposes, if you are receiving SSDI and also receive SDI, Social Security may offset your SSDI payment. This is because SSDI is meant to replace lost wages, and SDI also replaces lost wages. The two programs do not stack; instead, your SSDI is reduced by the amount of SDI you receive. This offset is separate from the tax treatment and happens at the benefit level, not on your tax return.

What to do if you receive a 1099 or tax form for SDI

You should not receive a 1099 for SDI, because the EDD does not issue one. If you do receive a form from the EDD reporting SDI as income, contact the EDD when ready to report the error. You can reach the EDD by phone or through their online account portal.

If a tax preparer or software program asks you to report SDI as income, stop and clarify the issue. SDI is not reported on any California or federal tax form. If you are using tax software, you may need to enter SDI in a field marked "non-taxable income" or "other income" so that the software does not accidentally include it in your taxable total. Read the software's instructions carefully, or ask a tax preparer for help.

Keep copies of any SDI payment statements or letters from the EDD showing the amounts you received. These are useful if the IRS or Franchise Tax Board ever questions your return, and they may also be needed to document your income for other programs.

Frequently Asked Questions

Do I have to report California SDI on my federal tax return?

No. SDI is not taxable to the federal government, so it does not appear on your federal Form 1040 or any federal form. You do not report it anywhere on your federal return.

If I receive both SSDI and SDI, are both tax-free?

Yes, both are tax-free. However, Social Security may reduce your SSDI payment by the amount of SDI you receive, because both programs are designed to replace lost wages. This offset happens at the benefit level, not on your taxes.

Can I claim the Earned Income Tax Credit if I only have SDI income?

No. The EITC requires earned income (wages or self-employment income). SDI alone does not may have access to. If you have both SDI and wages, you may be able to claim the EITC based on your wages.

What if my employer sends me a 1099 that includes SDI payments?

Contact your employer when ready and ask them to issue a corrected form. SDI is paid by the state, not your employer, and should never appear on a 1099 from your employer. If the error is not corrected, you may need to file an amended return or contact the Franchise Tax Board.

Does receiving SDI affect my may be able to access for Medi-Cal or CalFresh?

Yes. Although SDI is not taxable, it counts as income for Medi-Cal, CalFresh, and other means-tested programs. You must report SDI when explore for these programs, and it may affect your may be able to access or benefit amount.
