Tax Treatment of Workers’ Compensation Benefits: SSDI Offset and State Tax

Workers’ compensation benefits are not taxable under federal law. Section 104(a)(1) of the Internal Revenue Code excludes from gross income any amount received under a workers’ compensation act for personal injuries or sickness, and that exclusion applies to weekly wage-loss checks, permanent disability payments, medical expense reimbursements, and lump-sum settlements alike.¹ The severity of the injury, the length of the claim, and the state where you were hurt do not change the answer. IRS Publication 525 puts it plainly: workers’ comp benefits “are fully exempt from tax if they’re paid under a workers’ compensation act or a statute in the nature of a workers’ compensation act.”²

That language covers federal programs too. Payments under the Federal Employees’ Compensation Act for injury or sickness, including survivor benefits, are not taxable.³

There is one common situation where taxes creep in, and a few adjacent traps that catch people off guard. The exception first.

The One Exception: Social Security Disability Offset

If you collect Social Security Disability Insurance and workers’ comp at the same time, federal law caps the combined monthly total at 80 percent of your average current earnings before the disability. When the two together exceed that cap, the Social Security Administration reduces your SSDI check to bring you back under the limit.⁴

Here is the part that surprises people. Even though your actual SSDI cash payment is reduced, the SSA-1099 you receive at year-end reports the full pre-offset SSDI amount in Box 5. The IRS requires you to use that higher number when calculating whether any of your Social Security benefits are taxable. Publication 915 is explicit that you do not reduce the Box 5 figure by the workers’ compensation offset.⁵

An example. Say your pre-injury average earnings were $4,000 a month, making the 80 percent cap $3,200. You get $2,000 in workers’ comp and were entitled to $1,500 in SSDI. Combined, that is $3,500, which is $300 over the cap, so SSA cuts your SSDI to $1,200. You actually receive $1,200. But your SSA-1099 shows $18,000 for the year ($1,500 × 12), not the $14,400 that hit your account. You run the Social Security benefits worksheet on $18,000.

Reporting the higher figure does not automatically mean tax is owed. Whether any of your Social Security benefits become taxable depends on your combined income, which is your adjusted gross income plus any nontaxable interest plus half of your Social Security benefits. Under 26 U.S.C. § 86, up to 50 percent of benefits may be taxable once combined income passes $25,000 single or $32,000 married filing jointly, and up to 85 percent may be taxable above $34,000 single or $44,000 joint.⁶ Many people receiving both benefits stay under the thresholds. A working spouse, investment income, or a pension can change that.

One related point: if an attorney was paid out of your Social Security back pay, you cannot subtract that fee before calculating the taxable portion. Publication 915 lists attorney fees among the items that do not reduce the Box 5 figure.⁵

Don’t Confuse Workers’ Comp With Disability Insurance

Employer-sponsored short-term or long-term disability insurance is a different animal. If your employer paid the premiums and you collect on that policy, the benefits are taxable income and get reported on your return like wages.² The rule flips if you paid the premiums yourself with after-tax dollars, or if the employer paid them but included the premium cost in your taxable wages. In those cases the benefits come out tax-free.

Workers’ compensation sits outside that framework entirely. It is a statutory employer obligation, not a voluntary benefit plan, and it stays fully exempt regardless. Five states and Puerto Rico also run their own short-term disability programs separate from workers’ comp, with their own tax rules. If checks are arriving from more than one source after a workplace injury, confirm which program each one comes from before assuming any of them are tax-free.

Light-Duty Wages Are Taxable

When you return to work in a modified or light-duty role while still receiving partial workers’ comp benefits, the paycheck follows ordinary payroll rules. Wages for hours worked are earned income, subject to federal and state income tax withholding, Social Security tax, and Medicare tax. The workers’ comp checks you keep receiving stay tax-free. Nothing about the injury exempts the paycheck.

Watch your stubs during this transition. Money from your employer’s payroll system is taxable wages. Money from the workers’ comp insurer is not. Filing them the wrong way invites IRS notices.

Effect on the Earned Income Tax Credit

Workers’ compensation does not count as earned income for the Earned Income Tax Credit. The EITC formula uses taxable wages and self-employment income, and the IRS definition of earned income excludes nontaxable workers’ comp.⁷ If you spent most of the year on workers’ comp instead of working, your earned income figure drops, which can shrink or wipe out a credit your family relied on in prior years. It feels like a paycheck replacement. The IRS does not treat it that way.

If you worked light duty for part of the year, only those wages count toward EITC eligibility. Run the numbers before filing.

Investment Income From a Lump-Sum Settlement

A lump-sum workers’ comp settlement arrives tax-free. Once you invest it or park it in an interest-bearing account, the returns are taxable. Interest, dividends, and capital gains follow the ordinary investment rules. The original settlement keeps its tax-free character; the income it produces does not inherit that protection. If a settlement sitting in a savings account earns $2,000 in interest during the year, that $2,000 belongs on your tax return.

What You Actually Report on Your Return

Because workers’ comp is tax-exempt, insurers do not issue a Form 1099 or W-2 for those payments. Most recipients have nothing about workers’ comp to enter on Form 1040. If workers’ comp was your only income for the year, you may not need to file a federal return at all, though that depends on the rest of your situation.

The picture changes with an SSDI offset. You will get a Form SSA-1099, and Box 5 will show the full pre-offset amount. Use the worksheet in Publication 915 to figure the taxable portion and report it on Form 1040.⁵

State Income Tax

States overwhelmingly follow the federal treatment and exempt workers’ compensation from state income tax. A few have a reporting line where you acknowledge receipt of nontaxable benefits, which does not change the tax-free status. Rules vary, so check your state’s department of revenue guidance if you want certainty about local requirements.
