If you receive disability benefits, you know how difficult it is to obtain them. The last thing anyone wants is an unexpected tax bill on top of everything else. Unfortunately, many recipients of disability benefits are unaware of their obligations and, as a result, some unknowingly overpay or underpay the Internal Revenue Service (IRS).

At Tabak Law, we believe that informed clients make better decisions. This guide explains the federal tax rules for Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI), so you know exactly what to expect.

SSDI and SSI: Two Programs, Two Very Different Tax Outcomes

Before diving into the details of the tax rules for SSDI and SSI, it’s important to understand the fundamental differences between these two programs and how the IRS treats them. SSDI is an earned benefit paid to workers who have accumulated enough work credits and paid Social Security taxes throughout their careers. In contrast, SSI is a needs-based program that provides assistance to individuals with limited income and resources regardless of their work history, and it is funded by general U.S. Treasury revenues. 

Because of these structural differences, the two programs are subject to completely different tax treatments. While SSDI benefits are generally exempt from federal income tax, SSI benefits are not. It’s essential to consult with a tax professional to fully understand the specific tax implications of each program and your individual circumstances.

Is SSDI Taxable?

Yes, SSDI benefits may be taxable at the federal level, but only if your total income exceeds certain thresholds. According to 26 U.S.C. § 86 of the Internal Revenue Code, Social Security disability benefits are considered to be the same as retirement benefits for tax purposes. The amount of tax you owe depends on the figure called your combined income by the IRS.

How Combined Income Is Calculated

As detailed in IRS Publication 915, your total income is equal to your adjusted gross income plus any tax-exempt interest you earn and 50% of your Social Security benefits received during the year. After calculating this amount, the IRS uses a tiered system to determine how much of your Social Security Disability Insurance (SSDI) income will be taxed.

The Income Thresholds You Need to Know

For single filers and heads of households, if your combined income is below $25,000, none of your Social Security Disability Insurance (SSDI) benefits are taxable. If your income falls between $25,000 and $34,000, up to half of your benefits may be included in your taxable income. For married couples filing jointly, these same thresholds apply, but the amounts are $32,000 and $44,000.

It’s worth noting that the term “85% taxable” doesn’t mean you’ll pay 85% in taxes. It simply means up to 85% of your benefit will be included in your taxable income and will be taxed at your regular marginal rate.

Is SSI Taxable?

Supplemental Security Income (SSI) is never subject to federal income tax. This is because SSI is funded through general Treasury revenues, rather than Social Security payroll contributions. As a result, it is entirely excluded from gross income under federal law, meaning you do not need to report SSI on your federal tax return. 

Receiving SSI will also not trigger a tax liability, regardless of how your other financial situation may look. Most states follow a similar approach and do not tax SSI payments. However, it’s always best to check with a qualified professional to confirm the specific rules in your state.

What About State Income Taxes on SSDI?

The tax treatment of Social Security Disability Insurance (SSDI) benefits varies depending on the state in which you reside. As of 2025, most U.S. states provide a complete exemption from state income taxes on these benefits. However, some states such as Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, Vermont and West Virginia may partially tax SSDI benefits, depending on your income level. The rules and thresholds for exemption vary by state, so it is important to check with your state’s Department of Revenue or consult with a local attorney familiar with disability laws in your area.

What SSDI Recipients Should Do at Tax Time

Each January, the Social Security Administration will send you a Form SSA-1099 that reports the total amount of Social Security Disability Insurance (SSDI) benefits paid to you during the previous calendar year. This information will be used along with your other income to calculate your total income and determine if any portion of your benefits may be taxable.

If you owe taxes on your benefits, you have two options. You can either pay the balance when filing your tax return or set up automatic withholding. By submitting Form W-4V to the Social Security Administration, you can choose to have a flat percentage (7%, 10%, 12% or 22%) withheld directly from your monthly benefits. This will help you avoid receiving a large tax bill in April.
