Whether you pay taxes on SSDI depends on your total income

You may owe federal income tax on your SSDI benefits, but only if your combined income exceeds a certain threshold. Combined income means your SSDI payments plus any other income you receive—wages, interest, pensions, or other benefits. The threshold is low: $25,000 if you file as single, or $32,000 if you file as married filing jointly.

If your combined income stays below that threshold, you owe no federal tax on your SSDI. If it goes above, you may owe tax on up to 85% of your benefits. This is not the same as paying tax on 85% of what you receive—it means the IRS counts up to 85% of your benefits as taxable income when calculating what you owe.

State income tax is separate. Some states do not tax SSDI at all. Others tax it the same way the federal government does. A few tax it differently. You need to check your own state's rules.

Key Takeaways

  • You only owe federal tax on SSDI if your combined income (SSDI plus all other income) exceeds $25,000 for single filers or $32,000 for married filers.
  • If you do owe tax, you pay it on up to 85% of your benefits, not on the full amount you receive.
  • The Social Security Administration sends you a Form SSA-1099 each January showing how much you received the previous year.
  • State tax rules vary—some states do not tax SSDI, while others follow federal rules or have their own thresholds.
  • You can ask Social Security to withhold taxes from your monthly payment so you do not owe a large amount at tax time.

How the IRS calculates taxable SSDI

The calculation has two steps. First, add up your combined income: your SSDI payments for the year, plus wages, interest, dividends, pensions, and any other income. Then subtract the threshold for your filing status ($25,000 single or $32,000 married filing jointly).

That number is your "excess income." Next, take the smaller of two amounts: either half of your excess income, or 85% of your total SSDI for the year. Whichever is smaller becomes the amount the IRS counts as taxable. This means most people with income just above the threshold pay tax on roughly half of what they receive above that line, not on all of it.

Example: You are single and received $12,000 in SSDI. You also earned $15,000 in wages. Your combined income is $27,000. Your excess income is $2,000 ($27,000 minus $25,000). Half of that is $1,000. The IRS counts $1,000 of your SSDI as taxable income. You do not owe tax on the full $12,000—only on $1,000 of it, taxed at your regular rate.

What form you receive and when

In January of each year, Social Security mails you a Form SSA-1099 showing how much you received in benefits during the previous year. This is the form you use when filing your taxes. It lists your total SSDI payments and any federal tax already withheld.

You must report this income on your federal tax return, even if no tax is owed. If you file taxes electronically, the form data is often pre-filled. If you file by mail, you attach the SSA-1099 to your return.

If you requested tax withholding from your SSDI payments (see below), the amount withheld appears on the SSA-1099. This reduces what you owe when you file, just as withholding from a paycheck does.

Asking Social Security to withhold taxes from your payment

You can request that Social Security deduct federal income tax from your monthly SSDI payment. This works the same way as tax withholding from wages—money is taken out each month, and you receive less, but you owe less (or nothing) when you file your return.

To set up withholding, contact Social Security and ask to complete Form W-4V (Voluntary Withholding Request). You choose a withholding rate: 7%, 10%, 15%, or 25% of your monthly benefit. You can change or stop withholding at any time by submitting a new form.

Withholding is optional. Many people use it to avoid a large tax bill in April. Others prefer to keep the full payment each month and handle taxes when they file. There is no penalty either way.

State income tax on SSDI

Thirty-eight states do not tax SSDI benefits at all, regardless of your income level. These states straightforward exclude SSDI from taxable income. If you live in one of these states, you owe no state tax on your benefits even if you owe federal tax.

The remaining states follow one of two approaches. Some use the same federal rules as the IRS—you owe state tax only if your combined income exceeds the threshold, and only on the portion the IRS counts as taxable. Others have different thresholds or different percentages. A few states tax SSDI more heavily than the federal government does.

You can find your state's rule by contacting your state tax authority or checking their website. If you live in a state that taxes SSDI and you owe state tax, you may want to request withholding for state taxes as well using Form W-4V.

What happens if you do not report SSDI on your taxes

Social Security reports your benefits to the IRS. If you owe tax and do not file a return or report your SSDI income, the IRS will eventually contact you. Penalties and interest accrue on unpaid taxes.

If you genuinely owe no tax because your income is below the threshold, you still do not have to file a federal return—but it is often worth filing anyway. If tax was withheld from your payment, filing gets you a refund. If you have other credits you may have access to for (like the Earned Income Tax Credit), filing can increase your refund.

Other income that affects your SSDI tax bill

Any income counts toward the combined income threshold. This includes W-2 wages, self-employment income, interest and dividends, rental income, pension or annuity payments, and distributions from retirement accounts. It also includes income from a spouse if you file jointly.

Some income does not count. Supplemental Security Income (SSI) is separate from SSDI and does not count toward the threshold. Gifts do not count. Return of principal from investments does not count—only the earnings do. Railroad Retirement benefits have their own tax rules and do not affect SSDI taxation.

If you are unsure whether a particular income source counts, ask a tax professional or contact the IRS directly. The threshold is low enough that even small amounts of other income can push you over it.

Frequently Asked Questions

Do I have to file taxes if I only receive SSDI and my income is below the threshold?

No, you are not required to file a federal return if your only income is SSDI and it is below the threshold. However, if tax was withheld from your payment, filing a return will get you a refund. If you have dependents or may have access to for other tax credits, filing may also increase your refund.

Can I reduce my SSDI tax bill by earning less money?

Yes. If your combined income is just above the threshold, earning less (or delaying income until the next year) can lower or eliminate your tax bill. However, SSDI has its own earnings rules that may affect your benefits if you work, so check with Social Security before making changes to your work.

What if I think the SSA-1099 is wrong?

Contact Social Security and ask them to review the amount. Bring your records of payments received. If Social Security confirms the amount is correct but you still disagree, you can file a dispute with the IRS when you file your tax return, or contact a tax professional for guidance.

Does my spouse's SSDI affect my taxes if we file jointly?

Yes. When you file jointly, you combine both spouses' incomes to determine if you are above the threshold. Both spouses' SSDI benefits count toward combined income. You may owe tax on both of your benefits if your household income is high enough.

What if I receive both SSDI and SSI?

SSI (Supplemental Security Income) does not count as income for SSDI tax purposes. Only your SSDI payments count. However, SSI has its own income and resource limits, and receiving SSDI may affect your SSI amount—these are separate issues from taxation.
