Under IRC Section 72(m)(7), the IRS defines disability as the inability to perform any substantial gainful activity because of a medically determinable physical or mental impairment that is expected to result in death or to last for a long and indefinite period.1Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts Meeting this definition is what lets you take money out of a retirement account before age 59½ without paying the 10% early distribution penalty on top of regular income tax.2Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions The standard is strict, and qualifying under another program’s disability rules does not mean you meet it.
The Two Prongs of the Statute
Section 72(m)(7) has two requirements, and both must be satisfied. You must be unable to engage in any substantial gainful activity because of a medically determinable physical or mental impairment. And that impairment must be expected either to result in death or to continue for a long and indefinite period.1Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts You also have to furnish proof of the disability in whatever form the IRS demands.
Duration is where many claims fail. A condition that is expected to improve in the foreseeable future does not qualify, even if it stops you from working right now. “Indefinite” means there is no reasonable expectation that the impairment will diminish enough for you to return to substantial gainful activity.3eCFR. 26 CFR 1.72-17 – Special Rules Applicable to Owner-Employees A serious back injury that doctors expect to heal within 18 months would not meet the threshold, even though you cannot work today.
There is a related rule that catches people off guard. An impairment the IRS considers remediable does not count as a disability. If your condition can be reduced with reasonable effort and without risk to your safety to the point where you could return to your customary or comparable work, you are not disabled for this purpose.3eCFR. 26 CFR 1.72-17 – Special Rules Applicable to Owner-Employees A correctable vision problem or a condition treatable through standard surgery can disqualify you even if you have not yet had the treatment.
How Substantial Gainful Activity Is Measured
The activity in question is not “any job at all.” Under 26 CFR 1.72-17(f)(1), the IRS looks at the work you customarily performed before the disability arose, or a comparable activity. The primary consideration is the nature and severity of your impairment, with secondary weight given to your education, training, and work experience.3eCFR. 26 CFR 1.72-17 – Special Rules Applicable to Owner-Employees
The narrower framing matters. If you were a construction worker and a spinal injury prevents heavy physical labor but not desk work, whether you qualify depends on whether desk work counts as a “comparable activity” given your background. Two people with the same diagnosis can land on opposite sides of this test based on what they did before.
Why SSDI Approval Is Not Enough
If you already receive Social Security Disability Insurance, it is natural to assume the IRS will accept that determination. It will not. Both programs use the phrase “substantial gainful activity,” but they define and measure it differently. Social Security applies a monthly earnings threshold ($1,690 for non-blind individuals in 2026) and evaluates whether you can perform any work that exists in the national economy.4Social Security Administration. Substantial Gainful Activity The IRS regulation focuses on your customary or comparable work and has no fixed dollar cutoff.
An SSDI award letter is not accepted as proof of disability for the Section 72(m)(7) penalty exception. There is no IRS guidance treating a Social Security determination as sufficient verification for a living account holder claiming the exception.5Ascensus. Navigating IRA Disability Distributions You need independent medical documentation that speaks to the IRC definition.
What the Exception Does Not Do
The disability exception waives only the 10% additional tax. The distribution itself remains taxable as ordinary income in the year you receive it.6Internal Revenue Service. Retirement Topics – Disability Withdraw $80,000 from a traditional IRA and you avoid the $8,000 penalty but still owe federal income tax on the full $80,000. A large distribution in the same year you receive disability insurance payments or other income can push you into a higher bracket, so plan around that.
Which Accounts the Exception Covers
The disability exception applies across most tax-advantaged retirement accounts. Qualified plans such as traditional pensions, 401(k)s, and profit-sharing plans are covered, along with 403(a) and 403(b) annuity plans. Traditional IRAs, SEP IRAs, SIMPLE IRAs, and SARSEPs also qualify.2Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
The Physician’s Statement You Need on File
You do not submit medical evidence with your return. You keep a physician’s statement in your records and produce it if the IRS asks.7Internal Revenue Service. Publication 524 – Credit for the Elderly or the Disabled A useful statement covers three areas:
- The diagnosis and medical facts, including clinical findings and test results that establish a medically determinable impairment.
- The functional limitations that prevent you from performing your customary work or a comparable activity.
- The prognosis, with a clear statement that the impairment is expected to result in death or continue for a long and indefinite period. The physician must certify that the condition has lasted or can be expected to last continuously for 12 months or more, or is expected to be fatal.7Internal Revenue Service. Publication 524 – Credit for the Elderly or the Disabled
The statute does not spell out which type of medical professional must sign. It requires proof of a medically determinable impairment in a form the IRS accepts. A licensed physician who has actually treated you and can speak to clinical findings is the safest choice. A vague letter from a provider who saw you once is the kind of documentation that falls apart during an audit.
Some conditions clearly meet the threshold: permanent blindness, loss of use of two or more limbs, advanced terminal illness. Others need more detailed documentation because the IRS has to understand why your specific impairment prevents substantial gainful activity given your particular background. A diagnosis alone is not enough.
Reporting the Exception on Your Return
How you claim the exception depends on how your custodian coded the distribution. Your retirement plan administrator or IRA custodian may issue Form 1099-R with distribution code 3 in Box 7, which flags a disability distribution.8Internal Revenue Service. Instructions for Forms 1099-R and 5498 When Code 3 appears, the IRS system already treats the distribution as disability-related, and you generally do not need to file Form 5329.
If your 1099-R shows distribution code 1 (early distribution, no known exception), you claim the exception yourself on Form 5329, Additional Taxes on Qualified Plans (Including IRAs) and Other Tax-Favored Accounts.9Internal Revenue Service. 2025 Instructions for Form 5329 This happens more often than people expect. Many custodians code conservatively and leave it to the taxpayer to assert the exception.
On Part I of Form 5329, Line 1 shows the total early distributions included in your income. On Line 2, enter the amount that qualifies for the disability exception and write exception number 03 in the box provided.9Internal Revenue Service. 2025 Instructions for Form 5329 Code 03 identifies the total and permanent disability provision. When the exception covers the full distribution, the taxable amount subject to penalty on Line 3 is zero and the additional tax on Line 4 is zero. Attach Form 5329 to your Form 1040 when you file.10Internal Revenue Service. Form 5329 – Additional Taxes on Qualified Plans (Including IRAs) and Other Tax-Favored Accounts
Skipping Form 5329 when your 1099-R does not carry an exception code is how people end up with an automatic penalty assessment. On a $50,000 withdrawal, that is a $5,000 bill that a single form would have prevented. After you file, the IRS may send a letter asking for a copy of your physician’s statement. Respond promptly, because delay can lead the IRS to assess the penalty and charge interest while it waits.
Claiming the Exception for a Prior Year
If you paid the 10% penalty in a past year because you did not know about the exception or did not have documentation ready, you can file an amended return and recover the money. Use the prior year’s Form 5329 with Form 1040-X, Amended U.S. Individual Income Tax Return.11Internal Revenue Service. Instructions for Form 5329 If Form 5329 is your only change, you can file the prior year’s Form 5329 on its own without a full 1040-X.
The refund deadline is three years from the date you filed the original return or two years from the date you paid the tax, whichever is later.12Office of the Law Revision Counsel. 26 USC 6511 – Limitations on Credit or Refund If you took a $60,000 early distribution three years ago and paid the $6,000 penalty, that money is recoverable inside the window. Given the amounts, past returns are worth a look.
