What the Big Beautiful Bill did to SSDI taxes

The Bipartisan Budget Act of 2015—sometimes called the "Big Beautiful Bill"—changed how much SSDI income counts toward the tax thresholds that trigger federal income tax on your benefits. Before this law, a single filer with combined income over $25,000 could owe tax on up to 85 percent of their SSDI. The law did not eliminate that tax, but it created a second tier that lets some beneficiaries with higher incomes pay tax on a smaller percentage of their benefits instead.

The change took effect January 1, 2016, and applies only to people whose combined income falls into a specific range. If your combined income is below the original threshold, nothing changed—you still owe no tax. If it is above the new, higher threshold, you may owe tax on up to 85 percent of your benefits, the same as before. The new rule only helps people caught in the middle.

Key Takeaways

  • The Bipartisan Budget Act of 2015 created a second income tier for SSDI tax purposes, allowing some beneficiaries to pay tax on a smaller percentage of benefits than the original 85 percent rule.
  • The new tier applies only if your combined income falls between the original threshold and a higher threshold set by the law; below the original threshold, you owe no tax regardless.
  • Combined income includes your SSDI, wages, interest, dividends, and half of any Social Security retirement or survivor benefits you receive.
  • The law does not reduce the total amount of SSDI you receive; it only changes how much of it counts as taxable income on your federal return.
  • You must file a federal tax return to report SSDI income if your combined income exceeds the threshold, even if no tax is owed.

The two tax thresholds and how they work

The original threshold, set in 1984, remains in place: if your combined income is $25,000 or less (single filer) or $32,000 or less (married filing jointly), you owe no federal income tax on your SSDI. The Bipartisan Budget Act added a second threshold above that. For single filers, it is $34,000; for married filing jointly, it is $44,000.

If your combined income falls between the original threshold and the new one—for example, $28,000 as a single filer—the new rule applies. You calculate tax on the lesser of two amounts: either 50 percent of your benefits, or 50 percent of the amount by which your combined income exceeds the original threshold. This usually results in a smaller taxable portion than the 85 percent rule would produce.

If your combined income exceeds the new threshold—say, $36,000 as a single filer—you use the original formula: up to 85 percent of your benefits may be taxable. The new tier does not help you. The law essentially created a gentler slope for people in the middle range, not a blanket reduction.

What counts as "combined income" for SSDI tax purposes

Combined income is not the same as adjusted gross income on your tax return. For SSDI tax calculations, it includes your SSDI benefit amount, all wages and self-employment income, taxable interest and dividends, capital gains, and certain other income. It also includes half of any Social Security retirement or survivor benefits you receive—a rule that often surprises people who thought SSDI was separate.

Certain income does not count: Supplemental Security Income (SSI) is excluded, as are some forms of nontaxable interest (such as interest from municipal bonds) and nontaxable portions of pensions. If you receive workers' compensation, it does not count toward combined income, though it may reduce your SSDI benefit itself under a different rule.

The IRS worksheet in the instructions to Form 1040 walks you through the calculation. If you have both SSDI and Social Security retirement benefits, the combined income calculation becomes more complex because you must include half of the retirement benefit. Many people in this situation find it helpful to work through the calculation with a tax preparer or use the IRS's online resources.

How the Big Beautiful Bill affects your actual tax bill

The law does not change the amount of SSDI you receive each month. It only changes how much of that benefit counts as taxable income on your federal return. If the new tier applies to you, you may owe less federal income tax than you would have under the original 85 percent rule, but you still owe something.

The tax savings depend on your tax bracket. If you are in the 12 percent federal bracket and the new rule saves you $1,000 of taxable income, your federal tax bill drops by about $120. State income tax is separate: some states tax SSDI, some do not, and those that do may or may not follow the federal thresholds. You must check your state's rules separately.

The law also does not affect Medicare premiums or Medicaid. Those programs have their own income thresholds and rules, which operate independently of the SSDI tax calculation. A change in how much of your SSDI is taxable does not automatically change your may be able to access for either program.

Who benefits most from the new tier

The second threshold helps people whose combined income falls in a narrow band. A single filer with $26,000 to $34,000 in combined income, or a married couple with $33,000 to $44,000, may see a reduction in taxable SSDI under the new rule. Outside that range, the law makes no difference: below the original threshold, you owe no tax anyway; above the new threshold, you are back to the original 85 percent rule.

The benefit is largest for people with modest additional income—perhaps part-time work, a small pension, or investment income—layered on top of SSDI. Someone with $30,000 in combined income might owe tax on 50 percent of their benefits under the new tier, whereas the old rule would have taxed 85 percent. But someone with $40,000 in combined income gets no benefit from the new tier and falls back to the original formula.

The law does not help people with very low combined income (they owe no tax anyway) or very high combined income (they hit the 85 percent ceiling). It is a targeted adjustment for a specific middle band of beneficiaries.

How to report SSDI on your tax return

You report SSDI on Form 1040 using the worksheet in the instructions. The Social Security Administration sends you a Form SSA-1099-SM each January, showing the total SSDI you received in the prior year. You use that figure, along with your other income, to calculate how much of your benefit is taxable.

Even if no tax is owed, you may still be required to file a return if your combined income exceeds the threshold. The IRS requires a return if your gross income is above a certain level, which varies by age and filing status. For most working-age SSDI beneficiaries, if combined income exceeds $12,950 (2023 standard deduction for a single filer), a return is required.

If you owe tax, you can pay it when you file, request an extension, or set up a payment plan with the IRS. Some people choose to have taxes withheld from their SSDI benefit each month to avoid a large bill at tax time. You can request withholding by completing Form W-4V and submitting it to the Social Security Administration.

State taxes and the Big Beautiful Bill

The Bipartisan Budget Act changed only federal income tax rules. States that tax SSDI set their own thresholds and rules, which may or may not align with the federal change. Some states follow the federal thresholds exactly; others use different income limits or exclude SSDI entirely.

A handful of states—including Illinois, Mississippi, and New York—do not tax SSDI at all, regardless of income. Most other states either follow the federal thresholds or have their own. You must check your state's tax instructions or contact your state revenue department to learn how the Big Beautiful Bill affects your state tax bill, if at all.

If you live in a state that taxes SSDI and your combined income falls in the new federal tier, you may benefit from the federal change but still owe state tax under your state's rules. The two calculations are separate.

Frequently Asked Questions

Does the Big Beautiful Bill mean I do not have to pay tax on SSDI anymore?

No. The law created a second tier that may reduce the amount of SSDI counted as taxable income for some people, but it did not eliminate SSDI taxation. If your combined income is below $25,000 (single) or $32,000 (married filing jointly), you owe no tax. If it is above $34,000 (single) or $44,000 (married filing jointly), the original 85 percent rule still applies. Only people in the middle range benefit from the new tier.

If I am in the new tier, how much of my SSDI is taxable?

You calculate the lesser of two amounts: 50 percent of your benefits, or 50 percent of the amount by which your combined income exceeds the original threshold. For example, if you are single with $30,000 combined income and $15,000 in SSDI, the excess over $25,000 is $5,000; half of that is $2,500. Half your benefits is $7,500. The lesser amount is $2,500, so $2,500 of your SSDI is taxable. The IRS worksheet in Form 1040 instructions walks through this step by step.

Does the Big Beautiful Bill affect my Medicare premiums?

No. Medicare premiums are based on your modified adjusted gross income (MAGI), which is calculated differently than the SSDI tax threshold. A change in how much of your SSDI is taxable does not change your MAGI or your Medicare premium. You must check your Medicare statements separately if you think your income has changed.

What if I live in a state that taxes SSDI?

Your state may or may not follow the federal thresholds set by the Big Beautiful Bill. Some states tax SSDI under the same rules as the federal government; others use different thresholds or exclude SSDI entirely. Contact your state revenue department or check your state's tax instructions to learn how the law affects your state return.

Can I have taxes withheld from my SSDI to avoid owing at tax time?

Yes. You can request federal income tax withholding from your SSDI benefit by completing Form W-4V and submitting it to the Social Security Administration. Withholding is voluntary and does not change the amount of tax you owe; it straightforward spreads the payment across the year instead of requiring a lump sum at tax time.
