California SDI payments are generally not taxable as federal income, but you may owe state tax on them in some cases

California State Disability Insurance (SDI) payments you receive are not subject to federal income tax. The Internal Revenue Service treats SDI as a social insurance benefit, similar to Social Security Disability Insurance (SSDI), and excludes it from your taxable income on your federal return.

California state income tax is different. Most SDI recipients pay no state tax on their benefits either, but there are exceptions based on your total income and filing status. If you have other income sources — wages, self-employment income, interest, or pensions — your SDI may become partially taxable at the state level.

The key factor is whether your modified adjusted gross income (MAGI) exceeds certain thresholds set by California. If it does, a portion of your SDI becomes taxable to California, even though it remains tax-free federally.

Key Takeaways

  • SDI payments are never taxable on your federal income tax return, regardless of how much you receive or what other income you have.
  • California state tax on SDI depends on your total income; if your MAGI is below the state threshold for your filing status, you owe no state tax on SDI.
  • If your MAGI exceeds the threshold, up to 85 percent of your SDI may become taxable to California, similar to how Social Security is taxed federally.
  • You do not receive a 1099 form for SDI; the state issues a 1099-G, which reports the gross amount but does not indicate federal taxability.
  • If you receive both SDI and other benefits like unemployment insurance or workers' compensation, the tax treatment of each is separate.

How California determines if your SDI is taxable

California uses a formula based on your modified adjusted gross income (MAGI). This is your adjusted gross income plus any tax-exempt interest, foreign earned income, and certain other items. The state then compares your MAGI to a threshold amount that depends on your filing status.

The thresholds are set by California law and have remained the same for many years. For the 2024 tax year, the thresholds are:

Filing StatusMAGI Threshold
Single$20,000
Married filing jointly$32,000
Married filing separately$0
Head of household$20,000

If your MAGI is at or below the threshold for your filing status, none of your SDI is taxable to California. If your MAGI exceeds the threshold, you calculate the taxable portion using a specific formula: the lesser of (1) 85 percent of your SDI, or (2) 85 percent of the amount by which your MAGI exceeds the threshold.

What counts as income when calculating your MAGI

When you determine whether your SDI is taxable, you must include all sources of income except those specifically excluded by law. Wages from employment, self-employment income, interest, dividends, capital gains, rental income, and pension or annuity payments all count toward your MAGI.

Some income sources do not count. Tax-exempt interest (such as interest from municipal bonds) is added back into MAGI for this calculation. Social Security benefits, however, are handled separately under federal rules and do not affect whether your SDI is taxable to California.

If you are married filing jointly, you combine both spouses' income to calculate MAGI. If you file married filing separately, each spouse's MAGI is calculated independently, and the threshold for that filing status is $0 — meaning any SDI is potentially taxable if either spouse has any other income.

Reporting SDI on your California tax return

You report SDI income on California Form 540 (or Form 540-2NR if you are a nonresident). The state sends you a Form 1099-G showing the total SDI you received during the tax year. This form is for information only; it does not tell you how much is taxable.

You must calculate the taxable portion yourself using the formula described above, or use California tax software that performs the calculation. If you use a tax preparer, bring your 1099-G and information about your other income sources so they can determine the correct amount.

If you owe California tax on your SDI, you pay it when you file your return. If you had SDI withheld during the year (which is rare), that withholding is credited against your tax liability. Most SDI recipients do not have tax withheld, so they either owe when they file or have no state tax due.

SDI combined with other income sources

If you receive both SDI and wages from part-time work, your MAGI includes both amounts. This can push you over the threshold and make your SDI taxable even if the SDI alone would not be. For example, if you are single and earn $15,000 in wages plus $8,000 in SDI, your MAGI is $23,000, which exceeds the $20,000 threshold. You would then calculate how much of your $8,000 SDI is taxable.

If you receive unemployment insurance (UI) in addition to SDI, both are reported separately. UI is taxable to California and federal governments (unless you were receiving SDI at the same time, in which case UI may be reduced). The tax treatment of UI does not affect the tax treatment of SDI.

Workers' compensation benefits are not taxable income and do not count toward your MAGI. If you receive workers' compensation and SDI at the same time, only the SDI calculation applies; workers' compensation does not push you over the threshold.

What to do if you think you owe tax on your SDI

Calculate your MAGI by adding all your income sources for the year. Compare it to the threshold for your filing status. If your MAGI is below the threshold, you owe no California tax on your SDI. If it exceeds the threshold, use the formula to calculate the taxable portion, or use tax software to do it for you.

If you did not have tax withheld and you owe California tax, you can pay it when you file your return. If you expect to owe tax in future years, you may want to request that SDI withhold a portion of your payment to cover the tax liability. Contact the California Employment Development Department (EDD) to set up withholding.

Keep your 1099-G and records of all other income for at least three years. If the EDD or California Franchise Tax Board audits your return, you will need to show how you calculated your MAGI and the taxable portion of your SDI.

Frequently Asked Questions

Do I have to pay federal income tax on my SDI?

No. SDI is excluded from federal taxable income under IRS rules. You do not report it on your federal Form 1040, and it does not affect your federal tax liability, even if you have other income.

Can I request that SDI withhold taxes from my payments?

Yes. You can contact the EDD and request that a portion of your SDI payment be withheld for California state income tax. This is optional, but it can help you avoid owing a large amount when you file your return.

What if my MAGI is exactly at the threshold?

If your MAGI equals the threshold for your filing status, none of your SDI is taxable. The threshold must be exceeded for any portion to become taxable.

Does SDI count as income for other purposes, like determining Medi-Cal or CalFresh benefits?

Yes. SDI is counted as income when you explore for means-tested programs like Medi-Cal, CalFresh, or housing information. The tax treatment and the benefit program treatment are separate; SDI being tax-free does not mean it is ignored for benefit calculations.

If I am married filing separately, why is the threshold $0?

California law sets the threshold at $0 for married filing separately filers to discourage that filing status. If you file separately and have any other income, any SDI you receive may be taxable. Filing jointly usually results in a lower tax burden if both spouses have SDI or other income.
