Yes, you may owe federal income tax on SDI benefits, but California does not tax them

California State Disability Insurance (SDI) payments themselves are not subject to California state income tax. However, the federal government treats SDI as taxable income on your federal return. Whether you actually owe tax depends on your total income for the year and your filing status.

The IRS considers SDI a form of wage replacement income. If SDI is your only income and it falls below the standard deduction for your age and filing status, you will owe no federal tax. If you have other income—wages, self-employment earnings, investment income, or Social Security—SDI counts toward your total, and you may cross into taxable territory.

You will not receive a 1099-G or other tax form from the state for SDI payments. The state does not report SDI to the IRS. This means you are responsible for tracking your SDI income yourself and reporting it correctly on your federal return.

Key Takeaways

  • California SDI is exempt from California state income tax, but the IRS treats it as taxable federal income.
  • You owe federal tax on SDI only if your total income exceeds the standard deduction for your filing status and age.
  • The state does not send you a tax form for SDI, so you must report the income yourself on your federal return.
  • If you receive both SDI and Social Security, the rules for taxing Social Security may change based on your combined income.
  • You can request that the state withhold federal taxes from your SDI payments to avoid a large bill at tax time.

How the IRS treats SDI income on your federal return

The IRS classifies SDI as taxable income under the category of disability benefits paid by a state program. You report it on line 1 of Form 1040 (U.S. Individual Income Tax Return) as wages or on Schedule 1 if you use that form, depending on your tax software or preparer's approach. Some tax software treats it as "other income" rather than wages, but the result is the same: it counts toward your gross income.

Your filing status and age determine your standard deduction—the amount of income you can earn before owing any federal tax. For 2024, the standard deduction is $14,600 for a single filer under 65, $17,550 for a single filer 65 or older, $29,200 for married filing jointly under 65, and $30,750 for married filing jointly with one spouse 65 or older. If your SDI income alone is below your standard deduction, you owe no federal tax on it.

If you have other income—part-time wages, self-employment income, interest, dividends, or capital gains—SDI adds to that total. Once your combined income exceeds your standard deduction, you begin to owe federal tax on the amount over the threshold.

Interaction with Social Security benefits

If you receive both SDI and Social Security Disability Insurance (SSDI), the tax treatment becomes more complex. SSDI is also taxable federally, and the IRS uses a formula called "combined income" to determine whether your Social Security is taxable. Combined income is your adjusted gross income plus nontaxable interest plus half of your Social Security benefits.

SDI counts as part of your adjusted gross income in this calculation. This means receiving both SDI and SSDI can push you into a tax bracket where some of your Social Security becomes taxable, even if neither program alone would trigger a tax bill. The IRS publishes worksheets in the instructions to Form 1040 to help you calculate this.

If you are unsure whether your combined income will make your Social Security taxable, a tax preparer familiar with disability income can walk through the calculation with you before the year ends, giving you time to plan.

Requesting federal tax withholding from SDI payments

You can ask the California Employment Development Department (EDD) to withhold federal income tax from your SDI payments. This is optional, but it can prevent you from owing a large amount when you file your return.

To request withholding, contact the EDD by phone at 1-888-353-1080 or through your online account at edd.ca.gov. You will need to specify a dollar amount or percentage to withhold each payment. The EDD will then reduce your payment by that amount and send the withheld funds to the IRS on your behalf.

Withholding is not required, and many people choose not to do it if their SDI income is low or if they have little other income. However, if you know you will owe tax, requesting withholding spreads the cost across the year rather than creating a surprise bill in April.

Reporting SDI on your tax return without a 1099

Because the state does not issue a tax form for SDI, you must manually enter the income on your return. Keep a record of all SDI payments you received during the year—your EDD account online shows payment history, and you can print or read a statement.

Add up the total SDI you received from January 1 through December 31. This is the amount you report on your federal return. If you use tax software, look for a field labeled "other income," "state disability," or "taxable benefits." If you work with a tax preparer, bring your EDD payment history with you.

The IRS does not cross-check your SDI income against EDD records the way it does with W-2 wages or 1099 forms, but that does not mean you should underreport. If the IRS audits your return and finds you omitted income, you will owe back taxes, interest, and penalties.

What happens if you do not report SDI income

Failing to report SDI on your federal return is tax evasion. The IRS can assess penalties and interest on unpaid taxes, and in cases of willful evasion, criminal charges are possible. More commonly, an audit will uncover the omission, and you will be required to pay the tax owed plus interest calculated from the original due date.

If you discover you missed SDI income on a prior-year return, you can file an amended return (Form 1040-X) for that year. Filing an amended return voluntarily, before the IRS contacts you, may reduce or eliminate penalties. The IRS generally has three years to assess tax on an unfiled or underreported return, though that period can extend to six years or longer in cases of substantial underreporting.

State tax credits and deductions that may offset SDI income

While California does not tax SDI itself, you may be may have access to to California tax credits or deductions that reduce your overall state tax bill. For example, if you have dependents, you may claim the California Child and Dependent Care Expenses credit. If you are low-income, you may be may have access to to the California Earned Income Tax Credit (CalEITC), which is separate from the federal EITC.

These credits and deductions do not directly offset SDI income—they reduce your state tax liability. However, they can make a meaningful difference if you have other income sources. A tax preparer or the California Franchise Tax Board's website can help you determine whether you may have access to.

Frequently Asked Questions

Do I have to file a federal tax return if SDI is my only income?

Only if your SDI income exceeds your standard deduction for the year. If you are single and under 65, your standard deduction for 2024 is $14,600. If your SDI was less than that, you have no federal filing requirement. However, if you had federal taxes withheld from your payments, you should file to claim a refund.

Will the EDD send me a tax form for SDI?

No. The EDD does not issue a 1099-G or any other tax form for SDI payments. You are responsible for tracking your total SDI income and reporting it on your federal return. Your online EDD account shows all payments received.

Can I deduct medical expenses or other disability-related costs from SDI income?

No. SDI is reported as gross income, and you cannot reduce it by deducting medical expenses, equipment, or other costs related to your disability. You may be able to claim medical expenses as an itemized deduction on Schedule A if they exceed 7.5% of your adjusted gross income, but this is separate from SDI reporting.

What if I received SDI by mistake and have to repay it?

If you repay SDI in the same year you received it, you can reduce your reported income by the repayment amount. If you repay it in a later year, you may be able to claim a deduction or credit for the repayment. Keep documentation of the repayment from the EDD, and consult a tax preparer about the best way to handle it on your return.

Does receiving SDI affect my ability to claim the Earned Income Tax Credit?

SDI is not earned income, so it does not count toward the EITC calculation. However, if you have wages or self-employment income in addition to SDI, that earned income may may have access to you for the EITC. The presence of SDI does not disqualify you from claiming the credit based on your other earnings.
