Whether your disability income is taxable depends on what kind of disability payments you receive and your total income for the year

Social Security Disability Insurance (SSDI) becomes taxable only if your "combined income" exceeds a certain threshold. Combined income means your adjusted gross income plus nontaxable interest plus half your SSDI benefits. If you are single and your combined income is over $25,000, or married filing jointly and over $32,000, part of your SSDI is taxable. If you are married filing separately, any SSDI at all may be taxable.

Other disability payments work differently. Supplemental Security Income (SSI) is never taxable, no matter how much you receive. Veterans' disability compensation is never taxable. Workers' compensation is never taxable. But disability payments from a private insurance policy, a pension plan, or an employer may be taxable depending on whether you or your employer paid the premiums.

The IRS does not automatically withhold taxes from SSDI, so if you owe tax, you may need to pay it yourself or request that Social Security withhold it from your monthly check.

Key Takeaways

  • SSDI becomes taxable only if your combined income (adjusted gross income plus half your SSDI) exceeds $25,000 for single filers or $32,000 for married couples filing jointly.
  • SSI is never taxable, and neither is veterans' disability compensation or workers' compensation.
  • If part of your SSDI is taxable, you can request that Social Security withhold federal income tax from your monthly payment.
  • You report taxable SSDI on Form 1040 or 1040-SR; Social Security sends you a Form SSA-1099 each January showing how much you received.

How the IRS calculates whether your SSDI is taxable

The IRS uses a formula called "combined income" to decide if any of your SSDI counts as taxable income. Combined income is your adjusted gross income (income from work, pensions, interest, dividends, and other sources) plus any nontaxable interest (such as interest from municipal bonds) plus half of your SSDI benefits for the year.

Once you know your combined income, compare it to the threshold for your filing status. For single filers, the threshold is $25,000. For married couples filing jointly, it is $32,000. For married couples filing separately, the threshold is $0 — meaning any SSDI may be taxable if you file separately.

If your combined income is below the threshold, none of your SSDI is taxable. If it is above the threshold, the IRS taxes either 50% or 85% of the amount over the threshold, depending on how far over you are. The calculation is complex, and the IRS worksheet on Form 1040 instructions walks through it step by step.

What counts as income that triggers SSDI taxation

Income from work is the most common reason SSDI becomes taxable. If you work part-time or full-time while receiving SSDI, your wages count toward your combined income. Self-employment income counts too. Interest and dividends from savings or investments count. Pension income, annuity income, and distributions from retirement accounts (including IRAs) count.

Some income does not count. Nontaxable Social Security benefits (if you receive both SSDI and retirement benefits, only the SSDI portion is tested) do not count. SSI does not count. Veterans' benefits do not count. Gifts and inheritances do not count. Workers' compensation does not count.

If you are unsure whether a particular payment counts as income, the IRS Publication 915 lists what does and does not count toward combined income.

Other disability payments and their tax treatment

Supplemental Security Income (SSI) is never taxable under any circumstances. You do not report it on your tax return, and it does not count toward the combined income threshold that makes SSDI taxable.

Veterans' disability compensation is never taxable. This includes disability payments from the Department of Veterans Affairs, whether service-connected or nonservice-connected.

Workers' compensation is never taxable, even if you also receive SSDI or other income.

Disability payments from a private insurance policy depend on who paid the premiums. If you paid the premiums with after-tax dollars, the payments are not taxable. If your employer paid the premiums and you did not include them in your income, the payments are taxable. If you paid some premiums and your employer paid others, part of the payment is taxable and part is not.

Disability payments from a pension or retirement plan are taxable as ordinary income, similar to pension distributions. The portion that represents your own contributions (basis) is not taxable, but the portion that represents employer contributions and earnings is taxable.

How to report taxable SSDI on your tax return

In January of each year, Social Security sends you a Form SSA-1099 showing the total SSDI you received in the previous year. You use this form to fill out your tax return.

If none of your SSDI is taxable (your combined income is below the threshold), you do not have to report it on your return. You can straightforward file your return without mentioning SSDI.

If part of your SSDI is taxable, you report it on Form 1040 or Form 1040-SR (the long form for people 65 and older). The IRS provides a worksheet in the Form 1040 instructions that walks you through calculating how much of your SSDI is taxable. You then enter the taxable amount on the appropriate line of your return.

If you use tax software or work with a tax preparer, you enter the total SSDI from your SSA-1099, and the software or preparer calculates the taxable portion using the IRS worksheet.

Requesting tax withholding from your SSDI payment

Social Security does not automatically withhold federal income tax from SSDI payments. If you know that part of your SSDI will be taxable and you want to avoid a tax bill at the end of the year, you can ask Social Security to withhold tax from your monthly check.

To request withholding, complete Form W-4V (Voluntary Withholding Request) and mail it to your local Social Security office or bring it in person. You can also request withholding by calling Social Security at 1-800-772-1213. You choose the withholding rate: 7%, 10%, 12%, or 22% of your monthly benefit.

If you request withholding, Social Security will withhold that percentage from every monthly payment going forward until you ask them to stop. You can change or cancel your withholding request at any time by submitting a new Form W-4V or calling Social Security.

Withholding is optional. Some people prefer to withhold and have less tax to pay in April. Others prefer to keep the full payment and pay tax when they file their return.

Special situations: Married couples and divorced beneficiaries

If you are married and file a joint return, your combined income includes both your income and your spouse's income, plus half of both your SSDI and your spouse's SSDI. This means that even if you have no income yourself, your spouse's income could push your combined income over the threshold and make your SSDI taxable.

If you are married and file separate returns, the rules are stricter. If you file separately and lived with your spouse at any time during the year, any SSDI you received is taxable. If you lived apart for the entire year, you use the $25,000 threshold for single filers.

If you are divorced and receiving SSDI on your own record, you use the single filer threshold of $25,000. If you are receiving benefits on your ex-spouse's record, the same rule applies — your combined income is tested against $25,000.

Frequently Asked Questions

Do I have to file a tax return if I only receive SSDI?

Not necessarily. If SSDI is your only income and it is below the standard deduction for your age and filing status, you do not have to file. For 2024, the standard deduction is $14,600 for single filers under 65 and $18,350 for single filers 65 and older. However, if you have other income (wages, interest, dividends), you may have to file even if your SSDI is not taxable.

What if I disagree with the amount shown on my SSA-1099?

Contact Social Security to verify the amount. You can call 1-800-772-1213 or visit your local office. Social Security will review your payment records and issue a corrected SSA-1099 if needed. Keep the corrected form for your tax records.

Can I deduct medical expenses related to my disability?

Yes, if your total medical expenses exceed 7.5% of your adjusted gross income, you can deduct the amount over that threshold on Schedule A (itemized deductions). This includes doctor visits, prescriptions, therapy, and other disability-related care. You must itemize rather than take the standard deduction to claim this.

If I work part-time, will my wages make all my SSDI taxable?

Not necessarily. Only the portion of your SSDI above the threshold is taxable, and even then, only 50% to 85% of that portion is taxable. If your combined income is just slightly over $25,000, only a small part of your SSDI becomes taxable. Use the IRS worksheet to calculate the exact amount.

What happens if I do not pay tax on taxable SSDI?

The IRS will assess penalties and interest on the unpaid tax. It is better to pay what you owe or request withholding from your SSDI payment. If you cannot pay in full, you can set up a payment plan with the IRS by calling 1-800-829-1040.
