Whether Your SSDI Is Taxed Depends on Your Total Income

SSDI benefits themselves are not automatically taxed. The IRS taxes them only if your combined income exceeds a threshold set by federal law. Combined income means your SSDI payments plus other income you receive — wages, interest, pensions, or certain other benefits. Most people receiving SSDI alone pay no federal tax on those benefits. But if you work part-time, receive a pension, or have investment income, you may owe tax on a portion of your SSDI.

The threshold is $25,000 for a single filer and $32,000 for married couples filing jointly. If your combined income stays below these amounts, you owe no federal tax on SSDI. If it exceeds the threshold, you may owe tax on up to 85 percent of your benefits, depending on how far over you go.

Some states also tax SSDI benefits, though most do not. The states that currently tax SSDI are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont. If you live in one of these states, you may owe state income tax on your benefits even if you owe no federal tax.

Key Takeaways

  • SSDI is taxed only if your combined income (SSDI plus other income) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • Combined income includes wages, self-employment income, pensions, interest, dividends, and certain other benefits — but not Supplemental Security Income (SSI).
  • If you exceed the threshold, you may owe tax on up to 50 percent of your benefits at the first tier and up to 85 percent at the second tier, depending on how much over you go.
  • Eleven states tax SSDI benefits: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont.
  • You can request that the Social Security Administration withhold federal income tax from your SSDI payments to avoid a large bill at tax time.

How Combined Income Is Calculated

The IRS defines combined income as your adjusted gross income plus nontaxable interest plus half of your SSDI benefits. This formula matters because it determines whether you cross the $25,000 or $32,000 threshold.

Wages from work count in full. Self-employment income counts in full. Taxable pensions, annuities, and distributions from retirement accounts count in full. Interest and dividends count in full. Nontaxable interest — such as interest from municipal bonds — also counts, even though it is not taxed as regular income.

Some income does not count. Supplemental Security Income (SSI) is excluded. Workers' compensation is excluded. Certain veterans' benefits are excluded. Gifts and inheritances do not count. The key is whether the IRS considers it taxable income or income-like for purposes of the combined income test.

If you are unsure whether a particular income source counts, the Social Security Administration publishes a detailed list in its Red Book, available on its website. You can also contact your local Social Security office or a tax professional.

The Two Tax Tiers and How Much You Owe

If your combined income exceeds the threshold, the tax does not explore to all your benefits. Instead, the IRS uses a two-tier system. The amount you owe depends on how far over the threshold you go.

Tier One: If your combined income is between the threshold and $9,000 above it (for single filers; $12,000 for married couples), you may owe tax on up to 50 percent of your benefits. The actual amount is the lesser of (1) half of the amount over the threshold, or (2) half of your total SSDI benefits. Most people in this tier owe tax on a smaller portion of their benefits.

Tier Two: If your combined income exceeds the Tier One ceiling, you may owe tax on up to 85 percent of your benefits. The calculation is more complex: it includes 85 percent of the amount over the second threshold, plus any amount already taxed in Tier One. In practice, very few people owe tax on 85 percent of their benefits; the maximum is capped at 85 percent of total benefits received.

The IRS publishes a worksheet each year to help you calculate the taxable portion. If the math is unclear, a tax professional or the Social Security Administration can walk you through it.

When You Receive a 1099-SSA Form

Each January, the Social Security Administration sends you a Form 1099-SSA showing the total SSDI benefits you received in the prior year. This form goes to you and to the IRS. You use it to report your benefits on your federal tax return.

The 1099-SSA shows only the gross amount of benefits paid. It does not calculate whether any portion is taxable — that is your responsibility based on your combined income. If you also received SSI, you will receive a separate Form SSA-1099 for that program; SSI is never taxable, and the form is for informational purposes only.

Keep your 1099-SSA with your tax records. If you file a tax return, you must report the amount shown on the form, even if none of it is taxable. If you do not file a return because your income is below the filing threshold, you do not need to submit the form, but keep it for your records.

Requesting Tax Withholding From Your SSDI Payments

If you know you will owe federal income tax on your benefits, you can ask the Social Security Administration to withhold money from your monthly SSDI payment. This prevents a large tax bill when you file your return and may reduce or eliminate the need to pay estimated taxes.

You request withholding by completing Form W-4V (Voluntary Withholding Request) and submitting it to your local Social Security office, by mail, or online through your my Social Security account. On the form, you choose a withholding rate: 7, 10, 15, or 25 percent of your monthly benefit.

The withholding is voluntary and can be changed or stopped at any time. If you change your income situation — for example, you stop working or start receiving a pension — you can adjust your withholding. There is no penalty for requesting withholding, and it does not affect your benefit amount; it straightforward reduces the payment you receive each month.

State Income Tax on SSDI

Most states do not tax SSDI benefits. However, Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont do tax them. The rules vary by state.

Some states use the same federal thresholds and tiers. Others have their own thresholds or tax all SSDI benefits above a certain age. A few states tax SSDI the same way they tax other income. If you live in one of these states, you will receive a state tax form (usually a 1099-equivalent) in addition to your federal 1099-SSA, and you will report your benefits on your state return as well.

If you move to a different state, your tax situation may change. If you move from a state that taxes SSDI to one that does not, you will owe state tax only for the months you lived in the taxing state. Contact your state tax authority or a tax professional if you are unsure how your state treats SSDI.

What Happens If You Do Not Pay Tax Owed

If you owe federal income tax on your SSDI and do not pay it, the IRS can assess penalties and interest. The penalty for underpayment is typically 0.5 percent of the unpaid tax per month, and interest accrues daily. If the IRS determines you owe a large amount, it may offset your future SSDI payments or pursue other collection methods.

If you cannot pay the full amount, you can request a payment plan or an offer in compromise (a settlement for less than you owe). The IRS also offers relief programs for taxpayers facing financial hardship. Contact the IRS directly or work with a tax professional to explore your options.

Filing your return on time, even if you cannot pay, reduces penalties. The failure-to-file penalty is steeper than the failure-to-pay penalty, so submitting your return by the important date is important even if you owe money.

Frequently Asked Questions

Do I have to file a tax return if I only receive SSDI?

Not necessarily. If SSDI is your only income and it is below the filing threshold for your age and filing status, you do not have to file. However, if you have other income or if any of your SSDI is taxable, you must file. When in doubt, filing is safer than not filing.

Does working part-time affect whether my SSDI is taxed?

Yes. Wages from work count toward your combined income. If your wages plus SSDI plus any other income exceed the threshold, a portion of your SSDI becomes taxable. This is separate from the work incentive rules that allow you to work and still receive SSDI; those rules determine whether you keep your benefits, while the tax rules determine whether you owe tax on them.

If I receive both SSDI and SSI, are both taxed?

SSDI may be taxed if your combined income is high enough. SSI is never taxed. You will receive separate forms for each program. The SSI amount does not count toward the combined income threshold for SSDI taxation.

Can I reduce my taxable SSDI by making charitable donations?

No. Charitable donations reduce your overall taxable income, but they do not reduce the combined income calculation used to determine whether your SSDI is taxable. The combined income threshold is fixed and does not change based on deductions or credits.

What if Social Security withheld too much tax from my benefits?

If you requested withholding and too much was taken out, you will receive a refund when you file your tax return. The IRS will refund the overpayment to you. You can also adjust your withholding rate on Form W-4V if you want to reduce the amount withheld going forward.
