If you received Social Security Disability Insurance (SSDI) benefits in 2020 and need to file taxes or verify your income, the document you're looking for is called the SSA-1099 — not a standard IRS 1099. Understanding exactly what this form is, where it comes from, and how to get a copy of a prior-year form helps you avoid wasted time chasing the wrong document.
The SSA-1099 (Social Security Benefit Statement) is issued by the Social Security Administration — not the IRS — each January. It reports the total SSDI benefits you received in the prior calendar year. For tax year 2020, this form would have been mailed in January 2021.
This form matters because SSDI benefits may be taxable, depending on your total income. If your combined income (adjusted gross income + nontaxable interest + half of your Social Security benefits) exceeds certain thresholds, up to 50% or 85% of your benefits could be subject to federal income tax. Whether that applies to you depends on your full financial picture — but the SSA-1099 is the starting document your tax preparer or tax software needs.
📋 Note: SSA-1099 is distinct from SSI (Supplemental Security Income) payments. SSI is not reported on an SSA-1099 because SSI benefits are not taxable and are not reported to the IRS.
There are several reasons someone might need a prior-year form rather than the most current one:
The SSA keeps records of prior-year benefit statements, so requesting the 2020 form is a standard process — it just requires a few specific steps.
The SSA's my Social Security portal at ssa.gov/myaccount allows you to view and download SSA-1099 forms going back multiple years, including 2020.
Steps:
If your account was created after 2020 or you weren't receiving benefits under your current account at the time, access may be limited — in which case, the options below apply.
Call 1-800-772-1213 (TTY: 1-800-325-0778). Representatives are available Monday through Friday, 8 a.m. to 7 p.m. local time. You can request that a replacement SSA-1099 for 2020 be mailed to your address on file. Standard processing typically takes 1–2 weeks.
You can walk into or schedule an appointment at your local SSA field office and request the form in person. Bring a government-issued photo ID. Staff can often print the document while you wait or confirm it will be mailed promptly.
| Form | Issued By | Reports | Taxable? |
|---|---|---|---|
| SSA-1099 | Social Security Administration | SSDI / retirement benefits | Possibly |
| 1099-R | IRS / pension payers | Pension, annuity, IRA distributions | Usually yes |
| 1099-MISC / 1099-NEC | IRS / employers | Self-employment, miscellaneous income | Yes |
| SSA-1099-SM | SSA | Benefits paid to multiple recipients | Possibly |
The SSA-1099-SM is a variation issued when benefits are paid to more than one person on the same record (for example, a beneficiary and a dependent). If you received this version in 2020, the download process is the same.
The SSA mails SSA-1099 forms in January of the following year to the address on file. If you moved, had mail issues, or simply didn't receive the January 2021 mailing, the SSA can reissue it. The online portal is typically the fastest path to recovering it.
One common snag: if you were newly approved for SSDI in 2020 and received back pay covering multiple prior years, your SSA-1099 for 2020 would reflect only what was paid in 2020 — which may differ significantly from what was owed for that year. Back pay is reported in the year it's received, not the year it covers. This distinction can affect how your benefits interact with your tax liability, a calculation that depends on your full income picture for that year.
Even with the SSA-1099 in hand, whether you owe taxes on those benefits depends on factors specific to your situation:
The SSA-1099 tells you what was paid. What it means for your tax liability is where individual circumstances take over.
