The forms you receive depend on whether you work while on SSDI

Social Security sends you a Form SSA-1099-SM (Social Security Benefit Statement) each January if you received SSDI payments during the previous year. This is not the same as a 1099 tax form. The SSA-1099-SM lists only the gross amount of benefits you got — it does not calculate how much is taxable, and you cannot use it to file your taxes directly.

If you also earned wages from work while receiving SSDI, your employer sends you a Form W-2 (Wage and Tax Statement) as usual. The W-2 reports your wages, taxes withheld, and Medicare tax. You will file both the SSA-1099-SM and the W-2 together when you complete your tax return.

If you are self-employed while on SSDI, you report your net earnings on Schedule C (Profit or Loss from Business) and file that with your 1040. Self-employment income counts toward the SSDI work incentive limits and may affect your benefits, so tracking it carefully matters both for taxes and for Social Security reporting.

Key Takeaways

  • Form SSA-1099-SM shows your total SSDI benefits but does not tell you how much is taxable — you must calculate that using IRS rules.
  • If you work and earn wages, you receive a W-2 from your employer and file it alongside the SSA-1099-SM.
  • Self-employment income must be reported on Schedule C and counts toward both your tax return and your SSDI work incentive limits.
  • The IRS, not Social Security, determines whether your SSDI is taxable based on your total income and filing status.

How the IRS decides if your SSDI is taxable

SSDI itself is not automatically taxable. The IRS taxes SSDI only if your combined income exceeds a threshold that depends on your filing status. Combined income means your adjusted gross income plus nontaxable interest plus half of your SSDI benefits.

For a single filer in 2024, if combined income is between $25,000 and $34,000, up to 50 percent of your benefits may be taxable. If combined income exceeds $34,000, up to 85 percent may be taxable. For married filing jointly, the thresholds are $32,000 and $44,000. These thresholds do not change with inflation and have remained the same since 1984.

Work income, investment income, and taxable pensions all count toward combined income. Even small amounts of earned income can push you over the threshold. A tax professional or the IRS Free File program can calculate the exact taxable amount for your situation.

When you must file a tax return

You must file a federal tax return if your gross income (wages, self-employment income, and taxable SSDI combined) exceeds the standard deduction for your filing status. For 2024, the standard deduction is $14,600 for a single person and $29,200 for married filing jointly. Age 65 and older raises the standard deduction by an additional $1,850 (single) or $1,500 per spouse (married).

Even if your income is below the standard deduction, you may want to file anyway. If your employer withheld federal income tax from your wages, filing a return can get you a refund. If you have a child and meet income limits, you may be able to claim the Earned Income Tax Credit (EITC), which requires filing.

Some states also tax SSDI, though most do not. Check your state tax authority's website to see whether you owe state income tax on your benefits.

Where to get Form SSA-1099-SM and what to do with it

Social Security mails Form SSA-1099-SM to your address on file by January 31 each year. If you do not receive it by early February, you can request a replacement by calling Social Security at 1-800-772-1213 or by visiting your local Social Security office.

You can also view and print your SSA-1099-SM online through your my Social Security account at ssa.gov. Log in, go to "Benefit Verification," and select the year you need. Printing it yourself means you do not have to wait for the mailed copy.

When you file your tax return, attach a copy of the SSA-1099-SM to your 1040. The IRS uses it to verify the amount of benefits you reported. Keep the original for your records.

How work income affects both your taxes and your benefits

If you work while on SSDI, you report your earnings to Social Security and to the IRS separately, but the two interact. Earned income reduces your SSDI payment once you exceed the Substantial Gainful Activity (SGA) threshold — $1,550 per month in 2024 for non-blind beneficiaries — but it also counts toward your combined income for tax purposes.

This means earning more can lower your SSDI check and increase your tax bill at the same time. Work incentives like the Plan to Achieve Self-Support (PASS) and Impairment Related Work Expenses (IRWE) can reduce the income Social Security counts, but they do not reduce the income the IRS counts for tax purposes.

Track your earnings month by month and report them to Social Security within the timeframe your local office specifies. Underreporting or overreporting can trigger an overpayment that you must repay, separate from any tax issue.

Filing your return with SSDI income

You file your tax return the same way as anyone else: on Form 1040 with all required schedules and forms attached. The SSA-1099-SM goes in the same envelope or upload folder as your W-2 and any other income documents.

On the 1040, you report the total amount from your SSA-1099-SM on the line for Social Security benefits. The IRS worksheet (included in the 1040 instructions) then walks you through calculating how much is taxable. If you use tax software, it usually does this calculation automatically once you enter the SSA-1099-SM amount.

If you cannot afford a tax preparer, the IRS Free File program offers free tax software to people earning under a certain threshold (usually around $79,000). Many community organizations and legal aid offices also offer free tax preparation for low-income filers.

What happens if you do not file or underreport SSDI

If you owe tax and do not file, the IRS can assess penalties and interest. If you underreport your income, the IRS may audit your return and demand back taxes plus penalties. These consequences are separate from any Social Security overpayment issue.

If Social Security discovers you underreported earnings to them, they will recalculate your benefits and send you a notice of overpayment. You then owe Social Security back the benefits you were not may have access to to receive. This can happen years later if Social Security cross-checks records with the IRS or your employer.

Filing accurately and on time protects you from both tax penalties and benefit overpayments. If you are unsure whether you owe tax, contact a tax professional or call the IRS at 1-800-829-1040.

Frequently Asked Questions

Do I have to file taxes if I only get SSDI and no other income?

Only if your combined income (half your SSDI plus any other income) exceeds the threshold for your filing status. Most SSDI-only beneficiaries do not owe tax. However, if your employer withheld tax from wages you earned, filing a return gets you a refund even if you do not owe.

What if I lost my SSA-1099-SM or it shows the wrong amount?

Request a replacement through your my Social Security account or by calling 1-800-772-1213. If the amount is wrong, contact Social Security to correct it before you file. The IRS will match your return to Social Security's records, so discrepancies can delay your refund.

Can I file my taxes electronically if I get SSDI?

Yes. E-filing is faster and more accurate than paper filing. You attach the SSA-1099-SM electronically just as you would a W-2. Most tax software handles SSDI income correctly if you enter the amount from your SSA-1099-SM.

Does my spouse's SSDI count toward my combined income for tax purposes?

No. Each person's SSDI is taxed separately based on their own combined income. If you are married filing jointly, you report your SSDI and your spouse reports theirs, but they do not combine for the purpose of calculating taxability.

What if I earned money from work but Social Security says I did not report it?

Contact Social Security when ready to correct the record. Bring pay stubs or a letter from your employer showing the dates and amounts you earned. Correcting it early prevents an overpayment notice later and protects your tax record.
