Whether you pay taxes on SSDI depends on your total income

Social Security Disability Insurance (SSDI) payments themselves are not automatically taxed. However, if your total income from all sources reaches a certain level, the federal government will tax a portion of your SSDI benefits. This means you might owe taxes even if SSDI is your only source of income—but only if you also have other money coming in, like earnings from work, interest, or pensions.

The threshold that triggers taxation is low. For 2024, if you are single and your "combined income" exceeds $25,000, you may have to pay taxes on up to 50 percent of your benefits. If you are married and filing jointly, the threshold is $32,000. Combined income includes your SSDI payments plus half of your SSDI benefits plus any other income you receive.

The math is confusing because it counts your SSDI twice in different ways. This is why many people with SSDI end up owing taxes when they thought they wouldn't. The best way to know whether you will owe is to add up all your income sources and compare the total to the thresholds for your filing status.

Key Takeaways

  • SSDI payments are taxable only if your total income from all sources exceeds $25,000 (single) or $32,000 (married filing jointly).
  • Combined income includes your SSDI amount, plus half your SSDI amount again, plus any wages, interest, pensions, or other income you receive.
  • If you owe taxes on SSDI, you can have Social Security withhold taxes from your monthly payment instead of paying a lump sum when you file.
  • State taxes on SSDI vary by state—some states do not tax SSDI at all, while others tax it the same way the federal government does.

How to calculate whether your SSDI is taxable

Start by gathering your income documents for the tax year: your SSDI benefit statement (Social Security sends this in January as Form SSA-1099), any W-2s from work, 1099 forms from interest or other income, and statements from pensions or annuities.

Then calculate your combined income using this formula: take your SSDI amount for the year, add half of that SSDI amount again, then add all other income (wages, interest, rental income, pension payments, and so on). The result is your combined income.

Compare that number to the threshold for your filing status. If you are single and your combined income is $25,000 or less, none of your SSDI is taxable. If it is more than $25,000, you may owe taxes. If you are married filing jointly, the threshold is $32,000. If you are married filing separately, the threshold is $0—meaning any combined income at all may trigger taxation.

The actual amount of SSDI that becomes taxable is calculated by Social Security and reported on your SSA-1099 form in January. You do not calculate it yourself; you report the taxable amount on your federal tax return.

Withholding taxes directly from your SSDI payment

If you know you will owe taxes on your SSDI, you can ask Social Security to withhold federal income tax from your monthly benefit payment. This way you pay taxes gradually throughout the year instead of owing a large amount when you file your return.

To set up withholding, contact Social Security and ask for Form W-4V (Voluntary Withholding Request). You can request this by phone at 1-800-772-1213, by visiting your local Social Security office, or by creating an account on ssa.gov and managing it online. You choose the withholding rate: 7 percent, 10 percent, 15 percent, or 25 percent of your monthly benefit.

Withholding is voluntary, but it often makes sense if you have other income. Without it, you might owe a large tax bill in April. With it, you spread the cost across twelve months and may even get a refund if too much is withheld.

State taxes on SSDI vary widely

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 owe no state income tax on your SSDI benefits.

The remaining states tax SSDI in different ways. Some follow the federal rule exactly—taxing SSDI only if your combined income exceeds the federal threshold. Others have their own thresholds, which may be higher or lower. A few states tax SSDI more aggressively than the federal government does.

Check your state's tax agency website or call your state income tax office to learn the rule for your state. The rule can change year to year, so it is worth checking every tax season if you live in a state that does tax SSDI.

What happens if you do not withhold and owe taxes

If you do not have taxes withheld and you owe federal income tax on your SSDI, you must file a tax return and pay what you owe. The IRS does not automatically know about your SSDI income—Social Security reports it to the IRS on your SSA-1099, but you are responsible for reporting it on your return.

If you do not file and do not pay, the IRS can assess penalties and interest on the unpaid amount. These charges grow over time. If you owe a large amount, you can contact the IRS to set up a payment plan, which allows you to pay in installments rather than all at once.

If you cannot afford to pay what you owe, the IRS has programs for people in financial hardship. You can request an installment agreement, ask for an offer in compromise (paying less than you owe), or request a temporary delay in collection. Call the IRS at 1-800-829-1040 to discuss your situation.

Other income that counts toward the taxation threshold

Any money you receive counts toward the combined income threshold that determines whether your SSDI is taxable. This includes wages from work, even part-time work. It includes interest from savings accounts and bonds. It includes rental income, pension payments, and distributions from retirement accounts like IRAs or 401(k)s.

It also includes income from self-employment, capital gains from selling investments, and alimony received. Essentially, if the IRS counts it as income on a tax return, it counts toward the SSDI taxation threshold.

The one major exception is Supplemental Security Income (SSI), which is a different program from SSDI. SSI payments do not count toward the SSDI taxation threshold, and SSI is generally not taxable at all. If you receive both SSDI and SSI, only the SSDI portion is subject to taxation based on your combined income.

Frequently Asked Questions

Can I work and still receive SSDI without owing taxes?

Yes, but only if your total income stays below the threshold. If you earn wages and receive SSDI, add your wages plus half your SSDI plus any other income. If the total is under $25,000 (single) or $32,000 (married filing jointly), you owe no federal tax on your SSDI. Many people work part-time and stay below the threshold.

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

Your SSA-1099 will show only the SSDI you actually received that year. Use that amount to calculate your combined income. If you started receiving SSDI in June, for example, your annual SSDI amount will be lower, which may keep you below the taxation threshold.

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

If SSDI is your only income and it is below the threshold for your filing status, you generally do not have to file a federal return. However, filing may be worth it anyway—you might be due a refund if taxes were withheld, or you might be due the Earned Income Tax Credit if you also had wages.

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

Contact Social Security and ask them to review the calculation. Bring your income documents and ask them to recalculate your combined income. If you believe there is an error, Social Security can issue a corrected SSA-1099. You can also contact the IRS if you believe the amount reported to them is wrong.
