The SSA sends you Form SSA-1099 if you received SSDI benefits during the tax year

The form you receive is called Form SSA-1099, not a standard 1099. The Social Security Administration mails it to you by January 31 each year if you got SSDI payments in the previous calendar year. The form shows the total amount of SSDI benefits you received—nothing more. It does not show taxes withheld, deductions, or whether your benefits are taxable. That information depends on your other income, and you make it yourself when you file your tax return.

You will receive one SSA-1099 per Social Security number. If you have a spouse who also receives SSDI, they get their own separate form. The form goes to the address Social Security has on file, so if you moved during the year, it may arrive at an old address. You can request a replacement by calling Social Security at 1-800-772-1213 or by visiting your local office.

Key Takeaways

  • Form SSA-1099 shows only your total SSDI benefits for the year; it does not tell you whether those benefits are taxable.
  • The form arrives by January 31 and is mailed to the address Social Security has on file, so update your address if you moved.
  • You need the amount from Box 5 of the SSA-1099 to complete your tax return, along with any other income you earned that year.
  • Whether your SSDI is taxable depends on your combined income (SSDI plus wages, interest, and other sources), not on what the form says.
  • If you did not receive an SSA-1099 by early February, contact Social Security to request a replacement or ask them to resend it.

Where to find the benefit amount on the form

The SSA-1099 is a one-page form. The top section shows your name, Social Security number, and the tax year. Below that are numbered boxes. Box 5 is the one you need for your tax return—it shows the total SSDI benefits you received that year, before any taxes or deductions.

The other boxes on the form are mostly empty for SSDI recipients. Box 1 shows federal income tax withheld, but most people receiving only SSDI have nothing withheld because SSDI is not automatically subject to income tax. If you elected to have taxes withheld from your benefits, that amount appears in Box 1. Box 3 shows Medicare tax withheld if applicable, though this is rare for SSDI-only recipients.

Do not confuse the SSA-1099 with a W-2 or a standard 1099-MISC. Those forms are used for wages and other income. The SSA-1099 is specific to Social Security benefits and looks different.

What the form does and does not tell you

The SSA-1099 tells you only one thing: how much SSDI you received. It does not calculate whether that income is taxable. It does not account for your spouse's income, your wages, your interest, or any other money you made. It does not tell you what to report on your tax return or what your tax liability is.

The IRS uses a formula called combined income to decide whether your SSDI is taxable. Combined income is your adjusted gross income plus nontaxable interest plus half your SSDI benefits. If your combined income exceeds a threshold (which varies by filing status), some or all of your SSDI becomes taxable. The SSA-1099 does not perform this calculation. You or your tax preparer does.

This is why two people can receive the exact same SSDI amount but have very different tax outcomes. One person with no other income may owe no tax on their SSDI. Another person with wages or a pension may owe tax on 50 to 85 percent of their SSDI. The form itself does not reflect this difference.

How to use the SSA-1099 when filing taxes

When you file your tax return, you report the amount from Box 5 of your SSA-1099 on the appropriate line of your tax form. If you use Form 1040, that line is typically in the "Income" section. If you use tax software, it will ask you for your Social Security benefits, and you enter the Box 5 amount there.

You will also need to complete Worksheet A (or Worksheet B if you are married filing separately) in the IRS instructions for Form 1040. This worksheet calculates your combined income and tells you whether any of your SSDI is taxable. The worksheet uses the Box 5 amount from your SSA-1099 along with all your other income sources.

If you work with a tax preparer or use tax software, give them the SSA-1099 along with any W-2s, 1099s for other income, and records of interest or dividends. The preparer or software will handle the calculation. You do not need to do it yourself unless you are filing without help.

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

If you received SSDI during the tax year but did not get an SSA-1099 by early February, contact Social Security. Call 1-800-772-1213 (TTY 1-800-325-0778) or visit your local Social Security office. Have your Social Security number ready and tell them you did not receive your form.

Social Security can resend the form by mail or, in some cases, provide the information over the phone. If you need the form urgently for tax filing, ask if they can give you the benefit amount verbally so you can file on time. You can attach a note to your return explaining that you are waiting for the official form.

Do not file your return without reporting your SSDI benefits, even if you do not have the form yet. The IRS will receive a copy of your SSA-1099 from Social Security, and if your return does not match, you may face a notice or audit. It is better to file with the amount you know you received and correct it later if needed.

Corrected forms and changes to your benefit amount

If Social Security made an error on your SSA-1099—for example, the amount is wrong or the form shows benefits you did not receive—they will send you a corrected SSA-1099, usually marked "CORRECTED" at the top. Use the corrected form when you file your return, not the original.

If your SSDI benefits changed during the year (for example, you had a work incentive period that ended, or your benefit was reduced), your SSA-1099 will show the total for the entire year, not the individual monthly amounts. The form does not break down benefits by month. If you need to know how much you received in a specific month, you can view your benefit history on your my Social Security account online or call Social Security.

Keep your SSA-1099 with your tax records for at least three years. The IRS can audit returns going back that far, and you may need to show the form as proof of your reported income.

Frequently Asked Questions

Do I have to report my SSDI on my tax return if I did not receive an SSA-1099?

Yes. The form is a record for you, but the IRS receives a copy directly from Social Security. If you received SSDI, you must report it on your return even if the form is lost or delayed. Report the amount you know you received and contact Social Security for the official figure if you are unsure.

What if the amount on my SSA-1099 is wrong?

Contact Social Security when ready. They will investigate and send you a corrected form if an error is found. Do not file your tax return using an incorrect amount. If you have already filed, you may need to file an amended return once you receive the corrected form.

Can I use my SSA-1099 to prove my income for a loan or housing process?

Yes. The SSA-1099 is an official record of your SSDI income and is widely accepted by lenders and housing programs as proof of income. You may also provide a benefit verification letter from Social Security, which you can request online or by phone.

Does the SSA-1099 show whether my benefits are taxable?

No. The form shows only the total amount you received. Whether that amount is taxable depends on your combined income, which includes wages, interest, and other sources. You determine taxability using the IRS worksheet, not the SSA-1099 itself.

What if I received both SSDI and SSI in the same year?

You will receive separate forms. SSDI comes on an SSA-1099. SSI comes on a different form (Form SSA-1099-SSI). Report both on your tax return if you received both. Only SSDI can be taxable; SSI is never taxable, so the SSI amount does not affect your tax calculation.
