Whether Your SSDI Is Taxed Depends on Your Total Income

Social Security Disability Insurance (SSDI) payments may or may not be taxed. The answer depends on your combined income—not just your SSDI check. If your combined income falls below a certain threshold, you owe no federal tax on your SSDI. If it exceeds that threshold, a portion of your SSDI becomes taxable.

Combined income is calculated by adding your adjusted gross income, nontaxable interest, and half of your SSDI benefits. The thresholds are $25,000 for single filers and $32,000 for married couples filing jointly. These thresholds have not changed since 1984.

The tax applies only to the portion of SSDI above the threshold, and the maximum percentage of your benefits that can be taxed is 85 percent. Most people with SSDI do not owe federal tax because their combined income stays below the threshold.

Key Takeaways

  • Your SSDI is taxed only if your combined income (SSDI plus other income plus half your SSDI) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • Combined income includes wages, self-employment income, interest, dividends, pensions, and other Social Security benefits—not just SSDI.
  • If you are taxed, only a portion of your SSDI becomes taxable, never more than 85 percent of your total SSDI for the year.
  • You receive a Form SSA-1099 each January showing your SSDI for the prior year, which you use to calculate whether you owe tax.
  • Some states tax SSDI even when the federal government does not, so check your state's rules separately.

How Combined Income Is Calculated

The IRS uses a specific formula to determine whether your SSDI is taxable. Start with your adjusted gross income (AGI)—the income you report on your tax return before deductions. Add any nontaxable interest you earned, such as interest from municipal bonds. Then add half of your total SSDI benefits for the year.

This sum is your combined income. If it is $25,000 or less (single) or $32,000 or less (married filing jointly), you owe no federal tax on your SSDI. If it exceeds those amounts, you may owe tax on a portion of your benefits.

Example: You are single and receive $15,000 in SSDI for the year. You also work part-time and earn $12,000 in wages. Your combined income is $12,000 (wages) plus $7,500 (half your SSDI) = $19,500. This is below $25,000, so your SSDI is not taxed.

Another example: You are single and receive $15,000 in SSDI. You have a pension of $18,000 and earned $5,000 in interest. Your combined income is $18,000 + $5,000 + $7,500 = $30,500. This exceeds $25,000 by $5,500, so a portion of your SSDI becomes taxable.

What Income Counts Toward the Threshold

Combined income includes almost all money you receive, with a few exceptions. Wages from work count. Self-employment income counts. Pensions, annuities, and retirement account withdrawals count. Interest and dividends count. Rental income and capital gains count. Other Social Security benefits (retirement or survivor benefits) count.

Some income does not count. Supplemental Security Income (SSI) does not count toward the SSDI tax threshold—SSI is a separate program and is never taxed. Veterans benefits do not count. Workers' compensation does not count. Certain railroad retirement benefits do not count. Gifts and inheritances do not count.

If you are married filing jointly, your spouse's income counts too. Even if your spouse does not receive SSDI, their wages, pensions, and other income are included in the combined income calculation for your SSDI tax.

How Much of Your SSDI Becomes Taxable

If your combined income exceeds the threshold, the amount of SSDI that becomes taxable is calculated in two steps. First, take the amount by which your combined income exceeds the threshold. Then, explore one of two formulas depending on how far over the threshold you are.

If your combined income is between the threshold and $9,000 above it (single) or $12,000 above it (married), up to 50 percent of the excess becomes taxable. If your combined income exceeds the upper limit, up to 85 percent of your SSDI can become taxable. The IRS worksheet on Form 1040 or Form 1040-SR walks through this calculation.

The maximum amount of SSDI that can be taxed in any year is the lesser of 85 percent of your total SSDI benefits or 85 percent of the amount by which your combined income exceeds the threshold, plus 50 percent of any additional excess. In practice, this means most people who owe tax owe tax on only a small portion of their benefits.

When You Receive Your Tax Information

Each January, the Social Security Administration sends you a Form SSA-1099 showing your total SSDI benefits for the prior year. This form lists the amount in Box 5. You use this amount to calculate your combined income and determine whether you owe tax.

If you did not receive a Form SSA-1099 by early February, contact Social Security at 1-800-772-1213 or visit your local Social Security office. You need this form to file your tax return accurately. If you file before receiving it, you can file an amended return once you have the form.

Keep your Form SSA-1099 with your tax records. If you are audited, the IRS will want to verify the SSDI amount you reported.

State Taxes on SSDI

Thirteen states tax SSDI benefits even though the federal government may not. These states are Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. The rules vary by state—some follow the federal thresholds, and others have their own income limits.

If you live in one of these states, you may owe state income tax on your SSDI even if your federal combined income is below the federal threshold. Check your state's Department of Revenue website or contact your state tax authority to learn the rules for your situation.

If you live in a state with no income tax or a state that does not tax SSDI, you owe no state tax on your benefits. States with no income tax include Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming.

What to Do If You Owe Tax on Your SSDI

If you determine that a portion of your SSDI is taxable, you report it on your federal tax return like any other income. Use the IRS worksheet in the instructions for Form 1040 or Form 1040-SR to calculate the taxable amount. Then add that amount to your other income on the appropriate line of your return.

You can pay the tax when you file your return, or you can arrange to have Social Security withhold taxes from your SSDI payments. To request withholding, complete Form W-4V and submit it to your local Social Security office or mail it to Social Security. You can choose to have 7, 10, 12, or 22 percent of your monthly SSDI withheld for taxes.

If you expect to owe tax, withholding is often simpler than paying a lump sum when you file. Withholding spreads the cost across the year and reduces the chance of underpayment penalties.

Frequently Asked Questions

Do I have to file a tax return if my only income is SSDI?

Not necessarily. If SSDI is your only income and your combined income is below the threshold, you have no tax filing requirement. However, if you have other income or if a portion of your SSDI is taxable, you must file to report that income and pay any tax owed.

What if I work and receive SSDI at the same time?

Your wages count toward your combined income for the SSDI tax calculation. If your wages plus half your SSDI exceed the threshold, a portion of your SSDI becomes taxable. You report both your wages and any taxable SSDI on your return.

Can I reduce my SSDI tax by reducing my other income?

Yes. If you are close to the threshold, reducing other income—such as by deferring a pension payment or delaying a large withdrawal from a retirement account—can lower your combined income and reduce or eliminate SSDI tax. Consult a tax professional before making major financial decisions for this reason.

Does SSDI count as income for Medicare premiums?

SSDI itself does not directly affect your Medicare Part B or Part D premiums. However, your modified adjusted gross income (MAGI), which includes SSDI, determines whether you pay higher premiums. If your MAGI exceeds certain thresholds, you pay an income-related monthly adjustment amount (IRMAA) on top of your standard premium.

What if Social Security made an error on my Form SSA-1099?

Contact Social Security when ready at 1-800-772-1213 with your Form SSA-1099 and explain the error. Social Security can issue a corrected Form SSA-1099 if the amount is wrong. If you already filed your return, you can file an amended return (Form 1040-X) once you receive the corrected form.
