The 401k early withdrawal penalty exceptions are a fixed list in federal tax law. Money taken from a 401(k) before age 59½ generally owes a 10% additional tax on top of regular income tax, unless the withdrawal fits one of the exceptions the IRS names. For 401(k)s, those include death, total and permanent disability, leaving the employer in or after the year of turning 55, unreimbursed medical expenses above 7.5% of AGI, birth or adoption, federally declared disasters, domestic abuse, terminal illness, one small emergency withdrawal per year, and a few others. An exception removes the 10% only. It does not remove the income tax.
This article explains a US federal tax rule as the Internal Revenue Service publishes it. It is general information, not tax, financial or legal advice, and it does not say whether anyone should take money out of a retirement plan. A CPA or enrolled agent, and the plan administrator named in the plan's summary plan description, are the people to ask about a specific account.
Sources read September 23, 2026. Several dollar amounts below come from the SECURE 2.0 Act and at least one is indexed for inflation, so each figure is given with the IRS source it came from. The current IRS page is the place to confirm any amount before relying on it.
What the 10% penalty actually is
The "penalty" is formally called an additional tax on early distributions. According to IRS Topic No. 558, Additional tax on early distributions from retirement plans other than IRAs (page last updated May 27, 2026, read September 23, 2026), the 10% applies to the portion of an early distribution that is includible in gross income, and it exists to discourage using retirement money for non-retirement purposes.
Three details in that description matter more than they first appear.
- It is on top of income tax. A pre-tax 401(k) withdrawal is ordinary income in the year it is received. The 10% is added to whatever income tax is already owed on it.
- It applies to the taxable portion. Money that would not be taxable anyway, such as a return of after-tax contributions, is not hit by the 10%. How Roth money is treated depends on its own rules, which are covered in where the tax hits on traditional and Roth accounts.
- It is reported on the tax return, not settled at the plan. The IRS topic page says the tax goes on Schedule 2 of Form 1040, and Form 5329 is used when the distribution code on Form 1099-R does not reflect an exception that applies.
The trigger age is 59½. A withdrawal before that age is "early" unless an exception covers it.
The three gates every early withdrawal passes through
Most explanations of 401k early withdrawal penalty exceptions stop at the list. The list only answers one of three separate questions, and mixing them up is the most common source of confusion.
| Gate | The question | Who answers it |
|---|---|---|
| 1. Plan permission | Does the plan allow a distribution at all right now? | The plan document and plan administrator |
| 2. The 10% additional tax | Does an IRS exception remove the 10%? | Federal tax law, as listed by the IRS |
| 3. Income tax | Is the withdrawal taxable income? | Federal tax law; usually yes for pre-tax money |
A 401(k) is an employer plan, and an employer plan can restrict when a still-employed worker takes money out. An IRS exception does not force a plan to pay. Equally, a plan that approves a withdrawal does not make it penalty-free. And clearing gates 1 and 2 still leaves gate 3: an exception is a tax waiver on the 10% only.
The IRS exception list, as it applies to a 401(k)
The source for this section is the IRS page Retirement topics: Exceptions to tax on early distributions (page last reviewed or updated December 11, 2025, read September 23, 2026). The IRS table has one column for qualified plans, which includes 401(k)s, and one for IRAs. The rows below are those the IRS marks as applying to qualified plans.
| Exception | What the IRS table says (summarized) | Amount or threshold stated by the IRS |
|---|---|---|
| Age | Distribution after the participant reaches 59½ | Age 59½ |
| Death | Distribution after the participant's death | None stated |
| Disability | Total and permanent disability of the participant | None stated |
| Separation from service | Leaving the employer during or after the year the employee reaches 55 | Age 55; age 50 for certain public safety employees |
| Medical expenses | Unreimbursed medical expenses | Portion above 7.5% of AGI |
| Birth or adoption | Qualified birth or adoption distribution | Up to $5,000 per child |
| Disaster recovery | Economic loss from a federally declared disaster | Up to $22,000 |
| Domestic abuse victim | Abuse by a spouse or domestic partner; distributions after December 31, 2023 | Lesser of $10,000 or 50% of the account |
| Emergency personal expense | One distribution per calendar year; after December 31, 2023 | Lesser of $1,000 or vested balance above $1,000 |
| Terminal illness | Employee certified by a physician as terminally ill | None stated |
| Equal payments | A series of substantially equal periodic payments | Calculated, not a fixed amount |
| Military reservists | Certain distributions to reservists called to active duty | None stated |
| IRS levy | Distribution because of an IRS levy on the plan | None stated |
| QDRO | Paid to an alternate payee under a qualified domestic relations order | None stated |
| Corrective distributions | Timely return of excess contributions or deferrals | None stated |
| ESOP dividends | Dividend pass-through from an ESOP | None stated |
| Automatic enrollment | Permissive withdrawal from an auto-enrollment feature | None stated |
On the domestic abuse figure, IRS Notice 2024-55 describes the $10,000 amount as indexed for inflation for years after 2024, so the dollar cap for the current year may be higher than the figure on the exceptions page. The IRS's own current guidance is the place to confirm it.
Exceptions that apply to IRAs but not to a 401(k)
This is where a large share of online answers go wrong. The same IRS table marks several well-known exceptions as not applying to qualified plans such as a 401(k):
- First-time homebuyer, up to $10,000: IRA only.
- Qualified higher education expenses: IRA only.
- Health insurance premiums paid while unemployed: IRA only.
The practical meaning is structural, not advisory. The same event, such as buying a first home, can be treated differently depending on which account type the money comes from. The differences between these account families are laid out in types of retirement accounts explained, from the 401(k) to the Roth. Moving money between account types has its own rules and timing, and whether any such move makes sense for a particular person is a question for a tax professional.
The reverse is also true. The separation-from-service rule at 55 is marked "No" for IRAs on the IRS table. It belongs to the employer plan.
The age-55 rule, read carefully
The separation-from-service exception is often shortened to "the rule of 55," and the shorthand hides its conditions. The IRS wording is that the employee separates from service during or after the year the employee reaches age 55. For public safety employees of a state or political subdivision in a governmental plan, the age is 50, and an IRS footnote extends the category to certain federal law enforcement officers, corrections officers, customs and border protection officers, federal firefighters, private-sector firefighters and air traffic controllers.
What the wording implies:
- The timing is about the calendar year. Under the "during or after the year" wording, a separation in the calendar year of the 55th birthday is within the rule, even if it happens before the birthday itself.
- It follows the separation, not the age alone. Turning 55 while still employed does not by itself open the exception.
- It is tied to the employer plan. Because the IRA column says "No," the exception is described as belonging to the qualified plan.
Whether the plan allows partial withdrawals after separation, or only a single lump sum, is a plan-level rule. The summary plan description and plan administrator hold that answer.
Hardship withdrawals are not a penalty exception
A hardship withdrawal and a penalty exception are two different things, and the IRS treats them separately. The IRS hardship distribution FAQ (page last reviewed or updated February 26, 2026, read September 23, 2026) states that hardship distributions are includible in gross income unless they consist of designated Roth contributions, that they may be subject to the additional tax on early distributions, and that a hardship distribution cannot be rolled over into an IRA or another plan. The same page says a plan may, but is not required to, offer hardship distributions.
So "hardship" answers gate 1, plan permission. It does not answer gate 2. A hardship withdrawal is penalty-free only if it also fits one of the exceptions in the table above, such as the medical expense exception.
The withholding trap that creates a penalty by accident
This is the part most exception lists skip. A withdrawal that was meant to be a rollover can turn into a penalized early distribution without anyone intending it.
The IRS rollover page (page last updated May 31, 2026, read September 23, 2026) says a retirement plan distribution paid to the participant is subject to mandatory 20% withholding, even if the participant intends to roll it over later. If only the net amount received is rolled over, the withheld portion is treated as a taxable distribution, and the IRS says it may be subject to the 10% additional tax unless an exception applies. The same page states that when the full gross amount, including the withheld 20% made up from other funds, is rolled over, the distribution is tax-free and the 10% is avoided.
In other words, the 10% can land on money the account holder never actually spent. The mechanics of that 60-day window belong to rollovers rather than withdrawals, but the penalty consequence sits here.
How an exception is actually claimed
The IRS does not apply an exception on its own initiative. It shows up through two documents.
- Form 1099-R from the plan. Box 7 carries a distribution code. According to IRS Topic 558, when code 1 (early distribution, no known exception) appears and the tax applies, the amount can go straight on Schedule 2.
- Form 5329 from the taxpayer. Topic 558 says Form 5329 is filed when an exception applies but the code on the 1099-R does not show it. The plan often does not know about a taxpayer's medical expenses or disability, so the code it reports may not reflect an exception that exists.
The records supporting an exception, such as medical bills, a physician's certification, or disaster loss documentation, are what a tax preparer or the IRS would look at. Which records apply to a specific case is a question for a CPA or enrolled agent.
The newer exceptions from SECURE 2.0, and their repayment windows
Several rows on the list are recent. The IRS exceptions page marks the domestic abuse and emergency personal expense exceptions as applying to distributions made after December 31, 2023, and IRS Notice 2024-55 (issued June 2024) sets out the detail.
- Emergency personal expense. The IRS table limits it to one distribution per calendar year, capped at the lesser of $1,000 or the vested balance above $1,000. The IRS Form 1099-R instructions state it may be repaid at any time during the 3-year period beginning the day after it was received, and that there are limits on later distributions of the same type.
- Domestic abuse victim. Notice 2024-55 describes a distribution made within one year of the abuse, capped at the lesser of the dollar limit or 50% of the vested balance, and allows repayment within a 3-year period.
- Plan adoption varies. Notice 2024-55 treats offering these distributions as a plan choice. Whether a specific 401(k) offers them is again gate 1.
Notice 2024-55 treats a repayment to a plan much like a rollover, and the IRS Form 8606 instructions note that a repayment made in a later year may mean filing an amended return for the year of the distribution. That is a filing question for a tax professional.
What an exception does not do
A calm reading of the rules leaves a short list of limits:
- It does not remove federal income tax on pre-tax money.
- It does not address state income tax, which follows each state's own law.
- It does not require a plan to release money.
- It does not restore the account. Money withdrawn stops growing tax-deferred inside the plan unless it is repaid under one of the repayment rules above.
For medical costs specifically, a Health Savings Account is a separate account type built around medical spending with its own tax treatment, described in how an HSA works and its triple tax layers. It is a different structure with different eligibility rules, not a substitute for a tax professional's view of a particular situation.
Frequently asked questions
What is the penalty for withdrawing from a 401(k) early?
According to IRS Topic No. 558 (updated May 27, 2026), an early distribution from a retirement plan before age 59½ generally owes a 10% additional tax on the taxable portion, on top of regular income tax, unless an IRS-listed exception applies.
Is a hardship withdrawal exempt from the 10% penalty?
Not by itself. The IRS hardship distribution FAQ (updated February 26, 2026) says hardship distributions may be subject to the additional tax on early distributions. A hardship withdrawal avoids the 10% only if it also fits a listed exception.
Does the first-time homebuyer exception apply to a 401(k)?
No. The IRS exceptions table (updated December 11, 2025) marks the first-time homebuyer exception, up to $10,000, as applying to IRAs and not to qualified plans such as a 401(k). Higher education expenses are also IRA only.
What is the rule of 55 for a 401(k)?
It is the IRS separation-from-service exception: an employee who leaves the employer during or after the year of turning 55 avoids the 10% on distributions from that employer's plan. Certain public safety employees qualify at 50. The IRS table marks it as not applying to IRAs.
How is a penalty exception claimed on a tax return?
IRS Topic No. 558 says Form 5329 is used when an exception applies but the distribution code in box 7 of Form 1099-R does not reflect it. A CPA or enrolled agent can confirm which exception code fits a specific withdrawal.
