What you need to file taxes on SSDI income

Whether you file taxes on SSDI depends on your total income for the year — not just your benefits. The Social Security Administration sends you a Form SSA-1099-SM each January showing how much SSDI you received. You'll use this form along with any other income you earned (wages, self-employment, interest, rental income) to figure out if you owe federal taxes.

The threshold for filing changes each year and depends on your age and filing status. For 2024, a single person under 65 with only SSDI income generally does not file unless they earned other income above a certain amount. But if you have wages, self-employment income, or other sources, you may owe taxes even if your SSDI alone would not trigger a filing requirement.

The IRS has a worksheet on their website that walks you through whether you must file. You can also call the IRS at 1-800-829-1040 to ask directly. If you're unsure, filing anyway is safer than not filing when you should have — the worst outcome is a refund.

Key Takeaways

  • You will receive a Form SSA-1099-SM in January showing your total SSDI for the previous year, which you use to complete your tax return.
  • Whether you must file depends on your total income from all sources, not SSDI alone, and the threshold changes yearly based on age and filing status.
  • If you have any earned income (wages or self-employment), you likely must file even if your SSDI is your main source of money.
  • The IRS worksheet or a call to 1-800-829-1040 can tell you whether filing is required in your specific situation.
  • Part of your SSDI may be taxable if your combined income exceeds a certain amount, but many SSDI beneficiaries pay no federal tax on their benefits.

How much of your SSDI is taxable

Not all SSDI is taxable. The IRS uses a formula called "combined income" to decide whether any of your benefits are subject to federal tax. Combined income is your adjusted gross income plus nontaxable interest plus half of your SSDI for the year.

If your combined income is below a certain threshold (called the "first bend point"), none of your SSDI is taxable. If it exceeds that threshold, up to 50 percent of your benefits may be taxable. If it exceeds a higher threshold (the "second bend point"), up to 85 percent may be taxable. These thresholds do not change with inflation and have remained the same since 1984.

For a single filer in 2024, the first bend point is $25,000 and the second is $34,000. For married filing jointly, they are $32,000 and $44,000. These numbers explore to your combined income, not your SSDI alone. Many SSDI beneficiaries have combined income below the first bend point and owe no tax on their benefits at all.

Gathering your documents before you file

Start by collecting your Form SSA-1099-SM, which Social Security mails to you by January 31 each year. If you did not receive it by early February, you can request a replacement by calling Social Security at 1-800-772-1213 or visiting your local Social Security office.

Next, gather any other income documents: W-2 forms from employers, 1099 forms for self-employment or contract work, 1099-INT for interest income, 1099-DIV for dividends, or 1099-R for retirement distributions. If you received unemployment benefits, you will have a 1099-G. If you have a spouse, collect their documents too.

Keep records of any deductions you plan to claim — mortgage interest statements (Form 1098), property tax receipts, charitable donations, medical expenses, or student loan interest statements. If you paid estimated taxes during the year, have those payment records ready. The more organized you are before you start, the faster the filing process moves.

Filing your return: three common routes

You have three main ways to file: on your own using tax software, with help from a tax professional, or through a free IRS program if your income is low enough.

Tax software like TurboTax, H&R Block, or TaxAct walks you through questions about your income and deductions, then generates your return. Most charge a fee ($60 to $150) unless you use the free version, which is available only if your income is below a threshold set by the IRS each year. The software calculates whether your SSDI is taxable and handles the combined income formula for you.

Free IRS programs are available if your income is below roughly $34,000 (the limit changes yearly). VITA (Volunteer Income Tax information) offers free tax preparation at libraries, community centers, and nonprofits nationwide. You can find a VITA site near you at irs.gov or by calling 211. AARP also offers free tax help for people 60 and older through their Tax-Aide program.

Tax professionals — CPAs, enrolled agents, or tax attorneys — charge a fee but handle everything for you and can answer questions about your specific situation. If your income is complex or you have concerns about how SSDI interacts with other benefits, a professional can be worth the cost.

When and where to file your return

The tax filing important date is April 15 each year (or the next business day if April 15 falls on a weekend). You can file as early as January 31, once you have received your Form SSA-1099-SM and any other income documents.

You can file electronically (online) or by mail. Electronic filing is faster — the IRS typically processes e-filed returns within 21 days, while paper returns take 4 to 6 weeks. If you are owed a refund, e-filing gets it to you sooner. If you owe taxes, you have until April 15 to pay, but filing early gives you time to arrange payment.

To file electronically, use IRS-approved tax software or work with a tax professional who files electronically. To file by mail, print your return and mail it to the IRS address for your state, which is listed in the tax software or on irs.gov. Keep a copy for your records.

What happens after you file

If you file electronically and are owed a refund, the IRS deposits it into your bank account within 21 days. If you file by mail, allow 4 to 6 weeks. You can check the status of your refund on irs.gov using the "Where's My Refund?" tool, which updates every 24 hours after your return is received.

If you owe taxes, you can pay online through irs.gov, by phone, by mail, or through your tax software. The IRS accepts payments in installments if you cannot pay the full amount at once — you can set up a payment plan on their website. If you cannot pay by April 15, file anyway to avoid penalties for not filing; penalties for late payment are smaller than penalties for not filing.

Keep a copy of your filed return and all supporting documents for at least three years. The IRS can audit returns from the past three years, and having your documents organized makes an audit much simpler if one occurs.

How SSDI taxes affect other benefits

Filing taxes on SSDI does not change your SSDI payment amount — the IRS and Social Security do not share information about your tax filing. However, if you are also receiving Supplemental Security Income (SSI), a different program, your income can affect your SSI payment. SSDI and SSI are separate programs with different rules.

If you are working and earning wages while on SSDI, you may be in a work incentive program like Impairment Related Work Expenses (IRWE) or Plan to Achieve Self-Support (PASS). These programs can reduce your countable income for SSDI purposes. Keep records of these expenses and report them to Social Security — they may lower your taxes or protect your SSDI payment if your earnings rise.

If you are married and your spouse works, filing status matters. Filing jointly may increase your combined income and make more of your SSDI taxable. Filing separately might lower your tax, but the rules are complex. A tax professional can model both scenarios for you.

Frequently Asked Questions

Do I have to file taxes if I only receive SSDI and no other income?

Not necessarily. If SSDI is your only income and it is below the filing threshold for your age and status, you do not have to file. For 2024, a single person under 65 with only SSDI generally does not file. However, if you have any other income — wages, interest, self-employment — you likely must file even if the amount is small.

What if I did not receive my Form SSA-1099-SM?

Call Social Security at 1-800-772-1213 and request a replacement. They can mail it or provide the information over the phone. If it is late January or early February, wait a few more days — the form is mailed by January 31 but may arrive late. You can also view your SSA-1099-SM online through your Social Security account at ssa.gov.

Can I file my taxes myself, or do I need a professional?

You can file yourself using tax software or a free IRS program like VITA if your income is below the threshold. Tax software walks you through the process step by step. A professional is helpful if your situation is complex — for example, if you have self-employment income, rental property, or concerns about how SSDI interacts with other benefits.

What if I owe taxes but cannot pay by April 15?

File your return anyway — the penalty for not filing is much larger than the penalty for late payment. You can set up a payment plan on irs.gov to pay in installments, or request an extension to give yourself more time. Interest accrues on unpaid taxes, but paying late is better than not filing.

Does filing taxes on SSDI change my benefit amount?

No. The IRS and Social Security do not share tax filing information, so filing taxes does not affect your SSDI payment. However, if you also receive SSI (a different program), your income can affect that benefit. If you are working and using a work incentive program, keep records of those expenses and report them to Social Security separately.
