SSDI appears on Form SSA-1099, not a W-2

Social Security Disability Insurance (SSDI) payments come to you on a Form SSA-1099, issued by the Social Security Administration. This is not a W-2 form — SSDI is not employment income, so your local Social Security office sends you the SSA-1099 instead of an employer sending a W-2.

You receive one SSA-1099 for each year you received SSDI payments. Social Security mails these forms in January, the same month W-2s arrive, so you can gather all your income documents together. The form shows the total SSDI you received during the calendar year in Box 5.

If you also work and earn wages, you will receive both a W-2 from your employer and an SSA-1099 from Social Security. You report both on your tax return in the year you received them, regardless of when Social Security paid the benefits themselves.

Key Takeaways

  • Form SSA-1099 is the document Social Security sends you each January to report your SSDI income for the previous year.
  • Box 5 on the SSA-1099 contains your total SSDI payments; this is the figure you use when calculating whether your benefits are taxable.
  • You may owe federal income tax on part or all of your SSDI, depending on your combined income from all sources, even though SSDI itself is not withheld.
  • If you also receive other Social Security benefits — such as spousal or survivor benefits — those appear on separate SSA-1099 forms, each showing only that benefit type.

Where Box 5 fits into your tax calculation

Box 5 on your SSA-1099 is the starting point for determining whether your SSDI is taxable. The IRS uses a formula based on your "combined income," which includes your SSDI, any wages you earned, interest, dividends, and other income sources. The formula is not straightforward — it involves adding half your SSDI to your other income and comparing that total to IRS thresholds.

For 2024, if you file as single and your combined income exceeds $25,000, some of your SSDI becomes taxable. If you file as married filing jointly, the threshold is $32,000. These thresholds have not changed since 1984, so they affect more beneficiaries each year as incomes rise. If your combined income is below the threshold, none of your SSDI is taxable, and you may not owe federal income tax at all.

The SSA-1099 itself does not tell you whether you owe tax — it only reports what you received. You or a tax preparer must do the calculation using the IRS worksheet in the instructions to Form 1040, or use tax software that handles SSDI taxation automatically.

SSDI is not subject to withholding, so you may owe at tax time

Unlike wages, SSDI payments have no federal income tax withheld. Social Security sends you the full amount each month. This means that even if part of your SSDI is taxable, you will not see tax taken out of your payment — you pay the tax when you file your return or through estimated tax payments during the year.

If you know you will owe tax on your SSDI, you can ask Social Security to withhold federal income tax from your monthly payment. You do this by completing Form W-4V and submitting it to your local Social Security office or online through your my Social Security account. You can choose to have 7%, 10%, 12%, or 22% of your payment withheld each month. This does not change the amount on your SSA-1099 — it only reduces the cash you receive and increases the tax already paid.

Many beneficiaries choose withholding to avoid a large tax bill in April. Others prefer to keep the full payment and pay the tax when they file. Either approach is legal; the choice depends on your cash flow and whether you expect to owe.

Reporting the SSA-1099 on your federal return

You report the amount from Box 5 of your SSA-1099 on line 5b of Form 1040 (the main federal income tax form for individuals). This line is labeled "Social security benefits." You also fill out the worksheet in the Form 1040 instructions to determine how much of that amount is taxable, then enter the taxable portion on line 5c.

If you use tax software, you enter the Box 5 amount when prompted for Social Security income, and the software calculates the taxable portion automatically. If you use a tax preparer, bring your SSA-1099 along with all other income documents — W-2s, 1099s for interest or dividends, and records of any other income.

You must file a federal return if your combined income exceeds the filing threshold for your age and filing status, even if none of your SSDI is taxable. For 2024, a single person under 65 must file if their gross income is $14,600 or more. The threshold is higher if you are 65 or older. Check the IRS website or your tax software to confirm the threshold that applies to you.

State income tax treatment varies

Some states tax SSDI; most do not. Thirteen states currently tax Social Security benefits to some degree: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The rules in each state differ — some tax only the portion that is also taxable federally, while others use their own formulas.

If you live in a state that taxes SSDI, you will report the same Box 5 amount on your state return, but the state may use a different calculation to determine the taxable portion. Some states offer exemptions or deductions that reduce the taxable amount. Check your state's tax agency website or ask a tax preparer familiar with your state's rules.

If you live in one of the 37 states that do not tax Social Security benefits, you do not report your SSDI on your state return at all, even if you owe federal tax on it.

What to do if you do not receive an SSA-1099

Social Security mails SSA-1099 forms by January 31 each year. If you do not receive yours by mid-February, contact Social Security at 1-800-772-1213 or visit your local Social Security office. You can also create or log into your my Social Security account online and view your SSA-1099 there — you can print it or read it as a PDF.

Do not file your tax return without your SSA-1099 or a copy of it. If Social Security has not sent it and you cannot retrieve it online, call Social Security and ask them to mail a duplicate or provide the information over the phone so you can note it on your return. If you file without reporting your SSDI income, the IRS will catch the discrepancy when Social Security files its copy of the form with them, and you will receive a notice asking you to amend your return.

Frequently Asked Questions

Do I have to file a tax return if I only receive SSDI and no other income?

Not necessarily. If your only income is SSDI and your combined income is below the filing threshold for your age and filing status, you do not have to file. However, if you had federal income tax withheld from your SSDI payments, you may want to file to get a refund of that tax.

What if I receive SSDI and also work part-time?

You report both your wages (on the W-2 from your employer) and your SSDI (on the SSA-1099) on your tax return. Your combined income determines whether any of your SSDI is taxable. You may also be subject to SSDI work incentives that affect your benefits; consult a work incentives planning specialist for guidance on how work affects your benefits and taxes together.

Can I amend my return if I made a mistake reporting my SSDI?

Yes. File Form 1040-X (Amended U.S. Individual Income Tax Return) with the corrected information. You have generally three years from the original filing date to amend. If you owe additional tax, you will also owe interest and possibly penalties from the original due date.

Does my SSA-1099 show taxes already withheld?

Only if you requested withholding on Form W-4V. If you did, the amount withheld appears in Box 6 of your SSA-1099. This counts as tax paid for the year, so it reduces the tax you owe when you file your return.
