What you need to know before filing

If you receive SSDI, you may or may not owe federal income tax on your benefits — it depends on your total income and filing status. The Social Security Administration sends you a Form SSA-1099-SM each January showing how much SSDI you received that year. You use this form along with any other income (wages, interest, pensions) to figure out whether you have to file a tax return.

The key number is your combined income: half of your SSDI benefits plus all your other income (wages, interest, dividends, rental income). If this combined income exceeds a certain threshold that depends on your filing status, some of your SSDI becomes taxable. If your combined income stays below the threshold, your SSDI is not taxed at all, even though you still receive the Form SSA-1099-SM.

You are not required to file a return just because you get SSDI. You only file if your total income — including the taxable portion of SSDI, if any — exceeds the standard deduction for your filing status and age.

Key Takeaways

  • The Social Security Administration sends Form SSA-1099-SM in January; use it to report SSDI income on your tax return.
  • Your SSDI is taxed only if your combined income (half your SSDI plus all other income) exceeds thresholds that vary by filing status: $25,000 for single filers, $32,000 for married filing jointly.
  • If you have no other income and your SSDI is your only source of money, you typically owe no federal income tax.
  • You can file on your own using free software, through a tax preparer, or with help from a volunteer tax clinic in your community.
  • If you owe taxes on SSDI, you can pay in full by the important date or set up a payment plan with the IRS.

Understanding the combined income calculation

The IRS uses a specific formula to determine whether your SSDI is taxable. Take half of your annual SSDI benefit amount and add it to all your other income sources — wages from work, interest from a savings account, dividends, rental income, pensions, or withdrawals from retirement accounts. This total is your combined income.

For a single filer, if combined income is between $25,000 and $34,000, up to 50 percent of your SSDI may be taxable. If combined income exceeds $34,000, up to 85 percent may be taxable. For married couples filing jointly, the thresholds are $32,000 and $44,000. If you are married filing separately, the threshold is $0 — meaning any combined income at all may trigger taxation of your SSDI.

The actual amount of SSDI that becomes taxable is calculated using a worksheet in IRS Publication 915, which is free and available on the IRS website. Many tax software programs and tax preparers do this calculation automatically once you enter your SSDI amount and other income.

When you must file a return

You must file a federal income tax return if your total income exceeds the standard deduction for your filing status and age. For 2024, the standard deduction is $14,600 for a single person under 65, and $18,350 for a single person 65 or older. For married couples filing jointly, it is $29,200 under 65, and $30,750 if one spouse is 65 or older.

If you receive SSDI and have no other income, you almost certainly do not need to file — your SSDI alone will not push you over the standard deduction. However, if you also work, receive a pension, have interest income, or have other earnings, you may need to file even if you do not owe tax. Filing can be worth doing anyway if you are due a refund or if you want to claim the Earned Income Tax Credit.

The safest approach: add up all your income for the year (including half your SSDI), compare it to the standard deduction for your age and filing status, and file if you are over the limit. If you are unsure, filing does no harm.

Getting your Form SSA-1099-SM and other documents

Social Security mails Form SSA-1099-SM to your address on file by January 31 each year. The form shows your total SSDI benefit for the previous year. If you do not receive it by early February, you can request a copy by calling Social Security at 1-800-772-1213 or by visiting your local Social Security office.

You will also need any other income documents: a W-2 from an employer, a 1099-INT from a bank (for interest), a 1099-DIV from an investment account (for dividends), or a 1099-R from a pension or retirement account. Gather all of these before you start your return.

If you lost a document or did not receive one, contact the organization that paid you the income. They are required by law to send you a copy by January 31.

Filing your return: your options

You have three main routes to file: on your own using free tax software, through a paid tax preparer, or with help from a volunteer tax clinic.

Free tax software: The IRS Free File program offers free tax software to people with income below a certain threshold (usually around $79,000). You can find participating software providers on the IRS website at irs.gov. These programs walk you through questions about your income, filing status, and deductions, and they calculate your tax automatically. You file electronically, which is faster and more accurate than paper.

Tax preparers: A tax preparer — whether a CPA, enrolled agent, or tax professional — can file your return for you. They charge a fee, which varies by location and complexity. If your situation is straightforward (just SSDI and maybe one other income source), the fee is usually modest.

Volunteer tax clinics: Many communities offer free tax preparation through programs like VITA (Volunteer Income Tax information) and TCE (Tax Counseling for the Elderly). These are staffed by trained volunteers and are free. You can find a clinic near you by visiting irs.gov or calling 211.

What to do if you owe taxes on SSDI

If your combined income is high enough that some of your SSDI becomes taxable, you will owe federal income tax on that amount. The amount owed depends on your total taxable income and your tax bracket. You can pay in full by the tax important date (usually April 15), or you can set up a payment plan with the IRS if you cannot pay all at once.

To set up a payment plan, file your return on time even if you cannot pay. Then contact the IRS at 1-800-829-1040 to arrange a plan. The IRS offers short-term plans (120 days or less) at no cost, and longer-term installment agreements for a small setup fee. Making payments on time keeps you in good standing and avoids penalties and interest.

Some people choose to have taxes withheld from their SSDI benefit each month so they do not owe a large amount at tax time. To do this, fill out Form W-4V and send it to your local Social Security office. This reduces your monthly benefit slightly but can make tax season simpler.

State income tax and SSDI

Most states do not tax SSDI benefits at all, even if the federal government does. However, a few states — including Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, and Vermont — tax SSDI under certain conditions. The rules vary by state.

If you live in one of these states, check your state tax agency's website or call them directly to find out whether you owe state tax on your SSDI. Some states exempt SSDI entirely; others tax it only if your income exceeds a certain threshold. A tax preparer familiar with your state's rules can guide you through this.

Frequently Asked Questions

Do I have to report SSDI on my taxes if I do not owe any tax on it?

You must report SSDI on your tax return if you file one, even if none of it is taxable. You report it using the Form SSA-1099-SM that Social Security sends you. However, if your income is below the standard deduction for your age and filing status, you do not have to file a return at all.

What if I work part-time and receive SSDI?

Your wages count as income for the combined income calculation. Add half your SSDI to your wages and any other income to see if you exceed the threshold for your filing status. You may owe tax on part of your SSDI, and you will definitely owe tax on your wages. File a return to report both.

Can I claim dependents or deductions if I receive SSDI?

Yes. SSDI does not change your ability to claim dependents, the standard deduction, or other deductions you are may have access to to. If you support a child or another dependent, you can claim them. If you own a home and pay mortgage interest or property taxes, you may be able to deduct those if you itemize.

What happens if I do not file a return when I should have?

If you owe tax and do not file, the IRS will eventually contact you. Penalties and interest accrue over time, making the debt larger. If you realize you missed a year, file that return as soon as you can. The sooner you file, the sooner you can resolve the debt and avoid further penalties.

Is there a free way to file if I have SSDI and other income?

Yes. The IRS Free File program is available to most people with SSDI and modest other income. VITA and TCE volunteer clinics also prepare returns for free regardless of income. Both options are legitimate and widely used.
