If workers’ comp is your only income, you generally do not need to file a federal tax return. Workers’ compensation is excluded from gross income under federal law, so it doesn’t count toward the income thresholds the IRS uses to decide who has to file. The complication is that “only income” is rarely as clean as it sounds. A little bank interest, a retirement withdrawal, a short stretch of light-duty pay, or an overlap with Social Security disability can each create a filing obligation on their own, even while your workers’ comp checks stay tax-free.
Why Workers’ Compensation Doesn’t Count
Federal law excludes workers’ compensation from gross income entirely. Under 26 U.S.C. § 104(a)(1), amounts received under a workers’ compensation act as compensation for personal injury or sickness are not counted as income for tax purposes.1Office of the Law Revision Counsel. 26 USC 104 – Compensation for Injuries or Sickness The exclusion covers weekly wage-replacement checks, lump-sum settlements, medical expense reimbursements, and rehabilitation costs. Weekly, monthly, or paid all at once, the tax treatment is the same.
Because those payments never enter gross income, they never push you across a filing threshold. If workers’ comp truly is your only source of money coming in, the IRS’s answer is no return required.
Where “Only Income” Quietly Stops Being Only Income
Most people who ask this question have at least one other trickle of income they haven’t factored in. Any of the following can trigger a filing obligation on its own:
- Bank interest and dividends. Interest on Form 1099-INT and dividends on Form 1099-DIV count as gross income. Small amounts add up when combined with anything else on this list.
- Retirement account distributions. Withdrawals from a traditional IRA or 401(k) are generally taxable. Qualified Roth distributions usually aren’t, if the account has been open at least five years and you’re over 59½.
- Self-employment or side work. Net earnings of $400 or more from freelance or side work require a return so you can pay self-employment tax, regardless of the standard filing thresholds.2Internal Revenue Service. Topic No. 554 – Self-Employment Tax
- Rental income or investment gains. Rent collected or profits from selling investments are gross income.
- Light-duty wages. If you returned to work in a reduced role while your claim is still open, the pay for that work is taxable wages, not workers’ comp. Your employer withholds income and payroll taxes on it just like any other paycheck.3Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income
- Interest on a structured settlement. The settlement itself stays excluded. If it pays out over time and earns interest, the interest portion is taxable and will show up on a Form 1099-INT.
Add up everything on that list. That total, not your workers’ comp, is what you compare to the filing thresholds.
The Social Security Disability Overlap
This is the situation most likely to catch people off guard. When you receive both workers’ compensation and Social Security Disability Insurance (SSDI), the Social Security Administration caps your combined benefits at 80% of your average earnings before the injury.4Social Security Administration. How Workers’ Compensation and Other Disability Payments May Affect Your Benefits If the combined amount goes over that cap, SSA reduces your SSDI check by the difference. That reduction is called the workers’ comp offset.
For tax purposes, the workers’ comp amount equal to that SSDI reduction is treated as if it were a Social Security benefit. Section 86 of the Internal Revenue Code applies this rule directly: when a Social Security benefit is reduced because of workers’ compensation, an equal slice of the workers’ comp counts as a “social security benefit” when figuring taxable income.5Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits
You’ll see this on your paperwork. Your Form SSA-1099 reports the full SSDI amount you would have received before the offset, not the smaller amount that actually hit your bank account.6Social Security Administration. DI 52150.090 – Taxation of Benefits When WC/PDB Offset Is Involved That higher figure is what you use when calculating whether any of your Social Security is taxable. IRS Publication 915 has the worksheets.7Internal Revenue Service. Publication 915 – Social Security and Equivalent Railroad Retirement Benefits
The workers’ comp itself remains nontaxable. But the offset mechanics can pull enough of your Social Security into taxable territory to create a filing obligation. If you’re receiving both benefits, walk through Publication 915 carefully or get help with the return.
2026 Filing Thresholds
You have to file a federal return when your gross income meets or exceeds the standard deduction for your filing status. For the 2026 tax year, the amounts are:8Internal Revenue Service. Revenue Procedure 2025-32 – 2026 Adjusted Items
- Single, under 65: $16,100
- Single, 65 or older: $18,150
- Married filing jointly, both under 65: $32,200
- Married filing jointly, one spouse 65 or older: $33,850
- Married filing jointly, both 65 or older: $35,500
- Head of household, under 65: $24,150
- Head of household, 65 or older: $26,200
- Married filing separately: $5, regardless of age9Internal Revenue Service. Check If You Need to File a Tax Return
That $5 figure for married filing separately is not a typo. It catches more people than any other line on the list.
Workers’ compensation does not go into these calculations. If you received $40,000 in workers’ comp and $500 in bank interest, your gross income is $500, and a single filer under 65 would not have to file. If you received $40,000 in workers’ comp plus a $17,000 401(k) distribution, your gross income is $17,000, and you would.
When to File Even Though You Don’t Have To
Filing when you’re not required can still be worth it. Two reasons come up most often:
Refundable credits. If you had earned income during part of the year before your injury, you may qualify for the Earned Income Tax Credit or the refundable portion of the Child Tax Credit. Those credits only come to you if you file a return to claim them.
Withheld tax. If your employer withheld income tax from your paychecks before you went on workers’ comp, that money is only refunded through a return. Skip the filing and you leave it with the government.
What Happens If You Should Have Filed and Didn’t
The failure-to-file penalty is 5% of the unpaid tax for each month the return is late, capped at 25% total. For returns due after December 31, 2025, the minimum penalty is $525 or 100% of the unpaid tax, whichever is less.10Internal Revenue Service. Failure to File Penalty The penalty only applies when you owe tax. If your return would have shown a refund or a zero balance, there’s no late-filing penalty, though any refund is forfeited if you wait more than three years to file.
For someone whose main income is workers’ comp, the realistic risk is overlooking a small taxable item, an SSDI offset amount or a retirement withdrawal, and not realizing a return was due. The dollar amounts can be modest and the percentage penalty still uncomfortable once interest accrues from the original due date. When in doubt, add up everything that isn’t workers’ comp, compare it to your threshold, and file if the number is close.
