Whether you file taxes depends on your total income, not just your SSDI

Social Security Disability Insurance (SSDI) payments themselves are usually not taxed as income. However, you may still need to file a tax return if you have other income — from work, investments, pensions, or other sources — that pushes your total above the filing threshold. The IRS sets different thresholds based on your age and filing status, and those thresholds change each year.

The key is that SSDI and other Social Security benefits are counted differently than wages or self-employment income. Up to 85% of your benefits can be taxable if your "combined income" (a specific calculation the IRS uses) exceeds certain amounts, but many people on SSDI have no other income and therefore file nothing at all.

If you are unsure whether you need to file, the IRS provides a worksheet to help you determine this. You can also contact the Social Security Administration or a tax professional to review your specific situation.

Key Takeaways

  • SSDI payments are not automatically taxed, but you must file a return if your other income exceeds the annual threshold set by the IRS for your age and filing status.
  • The IRS uses "combined income" — a calculation that includes half your SSDI benefits plus all other income — to determine whether any of your benefits are taxable.
  • If you have earned income from work while on SSDI, you almost certainly need to file, even if the amount is small.
  • Filing a tax return can sometimes benefit you, because it may may have access to you for tax credits like the Earned Income Tax Credit (EITC) even if you owe no tax.

How the IRS counts SSDI when calculating your tax filing requirement

The IRS does not treat SSDI the same way it treats wages. When deciding whether you must file a return, the agency uses a number called your combined income. This is calculated as: your adjusted gross income (AGI) plus nontaxable interest plus half of your SSDI benefits.

For 2024, if you are single and your combined income is $25,550 or more, you must file a return. If you are married filing jointly, the threshold is $32,200. These numbers change annually, and the IRS publishes updated thresholds each year. If you are over 65, the threshold is higher.

The reason half your SSDI is included in this calculation is that the IRS wants to capture people whose total resources are substantial, even if most of it comes from benefits. If you have no other income and receive only SSDI, your combined income will be low, and you will not be required to file.

When you have work income alongside SSDI

If you are working and receiving SSDI at the same time, you almost certainly need to file a tax return. Wages are counted in full toward your filing threshold, and even modest earnings can push you over the limit.

There is an additional reason to file in this situation: you may be may have access to to the Earned Income Tax Credit (EITC), a refundable credit that can result in a payment to you even if you owe no tax. The EITC is designed for people with low to moderate earned income, and many people on SSDI who work part-time may have access to. You must file a return to claim it.

Keep in mind that earning income while on SSDI also affects your benefits themselves — there are work incentives and limits that Social Security tracks separately from tax filing. Those are different rules, but they make it even more important to keep careful records of what you earned.

When SSDI becomes taxable income

If your combined income exceeds the threshold for your filing status, some of your SSDI benefits become taxable. The IRS uses a two-tier formula to determine how much: up to 50% of your benefits can be taxable at the first tier, and up to an additional 35% at the second tier, for a maximum of 85% of your total benefits.

This is a complex calculation, and most people do not do it by hand. If you reach this point, a tax professional or the IRS can help you work through it. The important thing to know is that even if some of your SSDI is taxable, you may still owe little or no tax depending on your other income and deductions.

You will receive a Social Security Benefit Statement (Form SSA-1099) each January showing how much you received in SSDI the previous year. This form tells you and the IRS the amount of your benefits, and it is what you use to calculate whether any portion is taxable.

Filing even when you may not be required to

Sometimes it makes sense to file a tax return even if you are not required to. If you had taxes withheld from other income during the year, filing allows you to claim a refund. If you are may have access to to the EITC or other refundable credits, filing is the only way to receive them.

Additionally, some government programs and benefits look at your tax return or your income tax filing status when determining your own benefits. Filing a return can create a record that helps you in other areas.

If you are on a tight budget and unsure whether filing will help you, a free tax preparation service can review your situation at no cost. The IRS maintains a list of free tax preparation sites, and many communities offer free tax help through organizations like VITA (Volunteer Income Tax information).

What documents you will need

To file your taxes, gather your Social Security Benefit Statement (Form SSA-1099), which Social Security mails to you each January. You will also need documentation of any other income: W-2 forms from employers, 1099 forms from self-employment or investment income, and records of any deductions you plan to claim.

If you are filing on your own using tax software, the software will walk you through what information to enter. If you are working with a tax professional or using a free tax preparation service, bring all your documents with you so they can review your complete picture.

Keep copies of everything you file for your records. The IRS can ask questions about your return for up to three years after you file, so holding onto your documents protects you if that happens.
