Updated August 14, 2026. Quick answer: code 3 is your payer saying it accepts the disability exception, so the 10% additional tax should not follow. It removes that and nothing else. On a $20,000 distribution at a 22% marginal rate, code 3 takes $2,000 off a $6,400 bill and leaves $4,400 standing — 68.8% of it. And the test it certifies is a tax test, not the Social Security one.
What the IRS tells the payer
The instruction for code 3 is the shortest in the table. It is a cross-reference and nothing else:
“3—Disability.”
IRS, Instructions for Forms 1099-R and 5498 (2026), Table 1
“For these purposes, see section 72(m)(7) and Rev. Rul. 85-105, 1985-2 C.B. 53.”
IRS, Instructions for Forms 1099-R and 5498 (2026), Table 1, code 3
There is no description, no list of qualifying conditions and no evidentiary standard. The IRS simply points the payer at a definition in the statute and leaves it there. That brevity is why custodians differ so much in how readily they will use the code.
The test is § 72(m)(7), and it is not the SSA’s test
Here is the definition the code points at:
“For purposes of this section, an individual shall be considered to be disabled if he is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or to be of long-continued and indefinite duration. An individual shall not be considered to be disabled unless he furnishes proof of the existence thereof in such form and manner as the Secretary may require.”
26 U.S.C. § 72(m)(7)
Now read the Social Security Act’s definition of the same word, which is the one an SSDI award is measured against:
“inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months”
42 U.S.C. § 423(d)(1)(A)
The first half of each sentence is nearly identical. The second half is not. The tax code asks for an impairment of long-continued and indefinite duration; Social Security asks for one that has lasted or can be expected to last a continuous period of not less than 12 months. A twelve-month impairment with a foreseeable end satisfies the second wording and is not obviously indefinite under the first. So an SSDI award is powerful evidence and it is not, on the face of the two texts, the same finding — which is exactly why some custodians will not issue a code 3 on the strength of an award letter alone. The statute also puts the burden in one place:
“An individual shall not be considered to be disabled unless he furnishes proof of the existence thereof in such form and manner as the Secretary may require.”
26 U.S.C. § 72(m)(7)
If you are receiving disability benefits and wondering what else changes, the SSDI-to-retirement switch at full retirement age is a separate question with a separate answer.
What code 3 does not do
The exception it certifies is an exception to one tax:
“attributable to the employee’s being disabled within the meaning of subsection (m)(7)”
26 U.S.C. § 72(t)(2)(A)(iii)
Subsection (t) is the 10% additional tax on early distributions. It is not the income tax. A distribution coded 3 is still ordinary income in the year you received it, and for most people that is the larger number of the two:
| Coded 1 | Coded 3 | |
|---|---|---|
| Distribution | $20,000 | $20,000 |
| Income tax at 22% | $4,400 | $4,400 |
| 10% additional tax | $2,000 | $0 |
| Total | $6,400 | $4,400 |
Code 3 is worth $2,000 here. It is 31.3% of the bill, and 68.8% of it survives the code entirely. People who read the code as “this distribution is not taxed” are reading it as roughly three times more generous than it is.
If the payer used code 1 instead
Code 3 is one of the three exceptions a payer is told to rule out before falling back to code 1:
“Use code 1 only if the participant has not reached age 59½, and you do not know if any of the exceptions under code 2, 3, or 4 apply.”
IRS, Instructions for Forms 1099-R and 5498 (2026), Table 1, code 1
“You do not know” is the operative phrase, and a custodian that has never been told about a disability does not know. The remedy is not to argue with the form. It is to claim the exception yourself on Form 5329, where the disability exception has its own number:
“03 Distributions due to total and permanent disability. You are considered disabled if you can furnish proof that you can’t do any substantial gainful activity because of your physical or mental condition.”
IRS, Instructions for Form 5329, exception 03
Note that the instruction to taxpayers uses the tax wording — “long, continued, and indefinite duration” — not the Social Security one. The full route for a wrong code is worth reading before you contact the payer, because a corrected form and a Form 5329 are different remedies with different costs.
It is box 7a now, not box 7
Every guide to this form, including the ones on this site written before today, calls it Box 7. For tax year 2026 that is the wrong box number:
“We renumbered box 7 and the ‘IRA/SEP/SIMPLE’ checkbox to boxes 7a and 7b and we added boxes 7c (Trump account) and 7d (Earnings on excess contributions).”
IRS, Instructions for Forms 1099-R and 5498 (2026), What’s New
The code itself is unchanged. What moved is the label: the distribution code is in box 7a and the IRA/SEP/SIMPLE tick is box 7b. If you are reading a 2025 form, it is box 7; if you are reading a 2026 form, it is box 7a; and the two boxes added alongside them are narrow — box 7d, for instance, only ever carries a Trump-account figure:
“Enter the total amount of earnings on the amount of excess contributions distributed from a Trump account that is entered in box 1.”
IRS, Instructions for Forms 1099-R and 5498 (2026), Box 7d
The more important point is the older one. The code records what the payer knew when it cut the cheque, and the instructions say as much: a payer is told to use code 1 — the one that means no exception — whenever it simply does not know.
“However, use code 1 even if the distribution is made for medical expenses, health insurance premiums, qualified higher education expenses, a first-time home purchase, a qualified reservist distribution, a qualified birth or adoption distribution, an emergency personal expense distribution, an eligible distribution to a domestic abuse victim, a terminally ill individual distribution, a qualified disaster recovery distribution, or a qualified long-term care distribution under section 72(t)(2)(B), (D), (E), (F), (G), (H), (I), (K), (L), (M), or (N).”
IRS, Instructions for Forms 1099-R and 5498 (2026), Table 1, code 1
So a code is a claim about the payer’s knowledge, not a ruling about your tax. Every code in one place: the code table. If yours is wrong: what to do about it.
What this page does not do
- It does not tell you whether you meet § 72(m)(7). That is a medical and evidentiary question and the statute puts the proof on you.
- It does not read the case law. The instruction also cites Rev. Rul. 85-105, which was not read at primary for this page and is not summarised from memory here.
- It does not cover state tax. Some states follow the federal exception and some do not; none of that is decided by the code in this box.
- The rates in the table are illustrative, chosen so the arithmetic is checkable.
