When You Have to Pay Tax on SSDI

You may owe federal income tax on your SSDI benefits if your combined income exceeds certain thresholds. Combined income is not just your SSDI payment — it includes wages, interest, dividends, and other income you receive during the year, plus half of your SSDI benefits themselves. The IRS uses this combined figure to decide whether any of your benefits are taxable.

For 2024, if you file as single and your combined income is over $25,000, some of your benefits become taxable. If you file as married filing jointly, the threshold is $32,000. If you are married filing separately, the threshold is $0 — meaning any combined income at all can trigger taxation. These thresholds do not change year to year, so they explore the same way in 2025 and beyond unless Congress changes the law.

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 states have their own thresholds. You need to check your state's tax rules directly or ask a tax preparer familiar with your state.

Key Takeaways

  • SSDI becomes taxable only if your combined income (SSDI plus other income) exceeds $25,000 for single filers or $32,000 for married filing jointly.
  • Combined income includes half of your SSDI benefits plus all wages, interest, pensions, and other income you received that year.
  • If you owe tax on your benefits, you can pay it when you file your return or request that the SSA withhold taxes from your monthly payment.
  • State tax rules vary — some states do not tax SSDI, while others follow federal rules or have different thresholds.
  • You must file a tax return to report your income and determine whether any benefits are taxable, even if you normally would not file.

How the IRS Calculates Taxable SSDI

The calculation has two steps. First, add up your combined income: all your wages, self-employment income, interest, dividends, pensions, and other income for the year, plus half of the SSDI benefits you received. This is your combined income figure.

Second, subtract the threshold that applies to your filing status. If you are single, subtract $25,000. If you are married filing jointly, subtract $32,000. If the result is zero or negative, none of your benefits are taxable. If the result is positive, up to 85 percent of that excess amount becomes taxable, though the total taxable amount cannot exceed 85 percent of your total SSDI benefits for the year.

Example: You are single and received $12,000 in SSDI for the year. You also earned $18,000 in wages. Your combined income is $18,000 + ($12,000 × 0.5) = $24,000. Since $24,000 is below the $25,000 threshold, none of your benefits are taxable. If you had earned $20,000 instead, your combined income would be $26,000, and $850 of your benefits would become taxable (85 percent of the $1,000 excess over the threshold).

Withholding Taxes From Your SSDI Payment

You do not have to wait until tax time to pay tax on your SSDI. You can ask the Social Security Administration to withhold federal income tax directly from your monthly benefit payment. This reduces the amount you receive each month but means you will owe less (or nothing) when you file your return.

To set up withholding, contact Social Security by phone at 1-800-772-1213, visit your local Social Security office, or create an account on ssa.gov and request withholding through your online account. You will need to tell them what percentage of your benefit you want withheld — typically 7, 10, 12, or 22 percent. You can change or stop withholding at any time.

Withholding is optional. Some people choose it because they know they will owe tax and prefer to pay gradually. Others prefer to keep the full payment and pay the tax bill when they file. There is no penalty either way, as long as you pay what you owe by the tax important date.

Filing Your Tax Return With SSDI Income

You must file a federal tax return if your combined income exceeds the threshold for your filing status, even if you would not normally file. The IRS needs to know about your SSDI to determine whether any is taxable.

When you file, you will report your SSDI on Form 1040 (the main individual income tax form). The Social Security Administration sends you a Form SSA-1099 by January 31 each year showing the total SSDI you received. Bring this form and all other income documents (W-2s, 1099s, bank statements showing interest) to a tax preparer, or use tax software that walks you through reporting SSDI income.

If you cannot afford to pay a tax preparer, the IRS runs the Volunteer Income Tax information (VITA) program, which offers free tax preparation at community centers, libraries, and nonprofits. You can find a VITA site near you at irs.gov/vita. Many sites can help you file even if you have SSDI income.

What Happens if You Do Not File

If you owe tax on your SSDI and do not file a return, the IRS will eventually contact you. They may assess penalties and interest on the unpaid tax. If you receive a notice from the IRS, respond promptly — ignoring it makes the debt larger and can lead to wage garnishment or other collection action.

If you cannot pay the full amount you owe, you have options. You can request a payment plan (called an installment agreement) that lets you pay over time. You can also request an offer in compromise if you truly cannot pay, though approval is difficult. Contact the IRS at 1-800-829-1040 to discuss your situation.

If you have not filed in prior years and owe back taxes, filing late is still better than not filing. The IRS can work with you on a payment plan, and filing stops penalties from growing. A tax professional or VITA volunteer can help you file back returns.

State Income Tax on SSDI

Thirteen states do not tax SSDI at all: Alabama, Arkansas, Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Mississippi, Missouri, Oklahoma, and Pennsylvania. If you live in one of these states, you do not owe state income tax on your SSDI, though you may still owe federal tax.

Most other states follow the federal rule: SSDI is taxable only if your combined income exceeds the federal threshold. A few states have different rules. Colorado, Connecticut, and Kansas have their own thresholds or exclusions. You can find your state's rule by searching "[your state] SSDI tax" or calling your state tax department.

If you live in a state that taxes SSDI and you owe state tax, you will report it on your state income tax return. Some states allow you to request withholding from your SSDI payment, similar to federal withholding. Contact your state tax department to ask.

Frequently Asked Questions

Do I have to file a tax return if my only income is SSDI?

Only if your combined income (SSDI plus other income) exceeds the threshold for your filing status. If SSDI is your only income and it is below $25,000 (single) or $32,000 (married filing jointly), you do not have to file. However, if you had taxes withheld, you should file to get a refund.

Can I reduce my taxable SSDI by claiming dependents or deductions?

No. The calculation of taxable SSDI is separate from your standard deduction or dependent exemptions. You cannot reduce the amount of SSDI that becomes taxable by claiming dependents. However, your standard deduction and other deductions do reduce your overall taxable income, which may lower your total tax bill.

What if I earned money from work while receiving SSDI?

Wages count as part of your combined income for tax purposes. If your wages plus half your SSDI exceeds the threshold, some of your benefits become taxable. Additionally, if you are under full retirement age and earning above the Social Security earnings limit ($23,400 in 2024), Social Security will reduce your monthly benefit — that is a separate rule from taxation.

Do I owe tax on back pay or a lump sum SSDI payment?

Yes. If you receive a lump sum payment covering several months or years of back benefits, the full amount counts as income in the year you receive it. This can push your combined income well over the threshold and make a large portion of your benefits taxable that year. A tax professional can help you understand the impact before you receive the payment.

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

Contact Social Security directly at 1-800-772-1213 or visit your local office with your payment records. If Social Security made an error, they will issue a corrected SSA-1099. If you have already filed your return, you can file an amended return (Form 1040-X) once you have the corrected form.
