Most SSDI recipients do not report their benefits as taxable income

Social Security Disability Insurance (SSDI) is not taxable income for federal tax purposes in most cases. You do not include it on your Form 1040 or any other federal tax return unless you have other income that pushes you over a specific threshold. The Social Security Administration sends you a Form SSA-1099 each January showing what you received, but that form is informational only — it does not mean the money is taxable.

However, there is one situation where part of your SSDI becomes taxable: if your "combined income" exceeds $25,000 (single filer) or $32,000 (married filing jointly). Combined income is a specific calculation that includes your SSDI, plus any wages, interest, dividends, or other income you earned. If you cross that threshold, you may owe tax on up to 85 percent of your SSDI benefits. This is rare for most SSDI recipients, but it happens when someone works part-time or has investment income alongside their benefits.

State taxes are different. Some states tax SSDI and some do not. You will need to check your state's rules separately, because federal tax law does not control this.

Key Takeaways

  • SSDI is not taxable on your federal return unless your combined income exceeds $25,000 (single) or $32,000 (married filing jointly).
  • Combined income includes your SSDI plus wages, interest, dividends, and other income — not just SSDI alone.
  • The Form SSA-1099 you receive is informational and does not automatically mean your benefits are taxable.
  • State tax rules for SSDI vary by state and are separate from federal rules.
  • If you work while receiving SSDI, you must track your earnings because they affect both your taxes and your benefit amount.

How the combined income threshold works

The IRS uses a formula called "combined income" to decide whether any of your SSDI is taxable. Combined income is calculated as: your Adjusted Gross Income (AGI) plus nontaxable interest plus half of your SSDI benefits. If that total exceeds $25,000 (or $32,000 if married filing jointly), then part of your SSDI becomes taxable.

Example: You receive $15,000 in SSDI for the year and earn $12,000 from part-time work. Your combined income is $12,000 (wages) plus $7,500 (half of SSDI) = $19,500. This is below $25,000, so none of your SSDI is taxable. You would report only the $12,000 in wages on your return.

Another example: You receive $15,000 in SSDI and have $15,000 in interest income from investments. Your combined income is $15,000 (interest) plus $7,500 (half of SSDI) = $22,500. Still below $25,000, so no SSDI is taxable.

If you do cross the threshold, the calculation of how much SSDI becomes taxable is complex and involves a two-tier system. The IRS worksheet for this is on Form 1040 instructions, or you can use tax software that handles it automatically. Many people in this situation use a tax preparer because the math is error-prone if done by hand.

What to do with your Form SSA-1099

Each January, the Social Security Administration mails you a Form SSA-1099 showing the total SSDI you received in the previous year. This form goes to you and to the IRS. You do not attach it to your tax return, and you do not report the amount shown on it as income on your Form 1040 — unless your combined income exceeds the threshold.

Keep the Form SSA-1099 with your tax records for that year. If you file a return, you may need to reference it to show the IRS what you received. If you do not file a return (because your income is too low to require one), you still keep it for your records.

If you lose your Form SSA-1099 or it arrives late, you can request a replacement from the Social Security Administration by calling 1-800-772-1213 or by logging into your my Social Security account online.

When you must file a return even if SSDI is not taxable

You may have to file a federal tax return even though your SSDI itself is not taxable, if you have other income. The IRS sets a filing threshold each year based on your age and filing status. For 2024, a single person under 65 must file if their gross income is $14,600 or more. If you are 65 or older, the threshold is $18,350. These thresholds change each year.

Gross income for this purpose includes wages, self-employment income, interest, dividends, and capital gains — but not SSDI. So if you work part-time and earn $10,000 in wages plus receive $12,000 in SSDI, your gross income is $10,000, and you may not have to file. But if you earn $15,000 in wages, you must file even though the SSDI is not taxable.

Even if you are not required to file, you may want to file anyway if you had taxes withheld from your wages. Filing lets you claim a refund of those withheld taxes.

SSDI and state income taxes

Federal tax law does not control whether states tax SSDI. Each state makes its own rule. Some states do not tax SSDI at all. Others tax it the same way the federal government does — only if combined income exceeds a threshold. A few states have different thresholds or different rules altogether.

You need to check your state's tax rules separately. Contact your state's department of revenue or visit its website to find out whether SSDI is taxable in your state. If you live in a state that taxes SSDI, you will file a state return in addition to your federal return, and the state return may include SSDI as income even if the federal return does not.

If you moved to a new state during the year, you may owe tax to both your old state and your new state for the portion of the year you lived in each. This is complicated, and a tax preparer familiar with your state's rules can help.

Working while receiving SSDI and tax reporting

If you work and receive SSDI, you must report your wages on your tax return (if you meet the filing threshold), and you must also report your work to Social Security. These are two separate requirements, and both matter.

For tax purposes, you report wages on Form 1040 or Schedule C (if self-employed). Your employer will send you a Form W-2 showing what you earned. You include this on your return whether or not your SSDI is taxable.

For Social Security purposes, you must report your earnings to Social Security because work affects your benefit amount. Social Security has a Substantial Gainful Activity (SGA) threshold — a monthly earnings limit. In 2024, the SGA threshold is $1,550 per month for non-blind beneficiaries. If you earn more than this, Social Security may reduce or stop your benefits. You must report your earnings to Social Security within the month you earn them, not just at tax time. Failing to report work earnings can result in overpayments that you must repay.

Frequently Asked Questions

Do I have to attach my Form SSA-1099 to my tax return?

No. The Form SSA-1099 is informational only. You do not attach it to your return or report the amount as income unless your combined income exceeds the threshold. Keep it with your records in case the IRS asks about it later.

What if I received SSDI for only part of the year?

Your Form SSA-1099 will show only the amount you actually received. Use that amount in the combined income calculation. If you started or stopped SSDI mid-year, the threshold ($25,000 or $32,000) still applies to your full-year combined income.

Can I deduct medical expenses related to my disability?

Yes, if your medical expenses are high enough. You can deduct unreimbursed medical expenses on Schedule A (itemized deductions) if they exceed 7.5 percent of your Adjusted Gross Income. This is separate from whether SSDI is taxable. A tax preparer can help you determine whether itemizing is worth it.

If I owe tax on part of my SSDI, how do I pay it?

You pay it the same way you pay any federal income tax — by including it in your total tax liability on your Form 1040. You can pay when you file, or you can set up a payment plan with the IRS if you cannot pay in full. If you expect to owe, you can also make quarterly estimated tax payments to avoid a large bill at tax time.

What if I disagree with the amount shown on my Form SSA-1099?

Contact Social Security directly at 1-800-772-1213 or through your my Social Security account. Social Security will review your account and send you a corrected Form SSA-1099 if there was an error. Do not file your tax return until the discrepancy is resolved.
