401(k) Early Withdrawal Penalty: The 10% Rule and Every Exception (2026)

The 401(k) early withdrawal penalty is 10% of the taxable amount, charged on top of ordinary income tax when you withdraw before age 59½ (IRC §72(t)). Exceptions eliminate it, including the rule of 55, death, disability, medical expenses over 7.5% of AGI, a QDRO, SEPP payments, and several SECURE 2.0 carve-outs such as a $1,000 emergency withdrawal.

The 10% rule

Distributions from a 401(k) before age 59½ incur a 10% additional tax on the taxable portion, on top of regular income tax, unless a statutory exception applies. The penalty dates to the Tax Reform Act of 1986 and applies automatically. Exceptions are not automatic, and you have to claim them.

If you’ve already taken the money out and you’re trying to find out what it’s going to cost, take a breath and go straight to the exception table below. More people qualify for an exception than realize it, and exceptions are claimed on your tax return rather than at the moment of withdrawal. That means a withdrawal that looks penalized on the paperwork can still end up penalty-free once you file. If you haven’t withdrawn yet, the cost example below is the number worth seeing first.

How much does an early 401(k) withdrawal actually cost?

It costs more than most people expect, because the penalty stacks on top of income tax rather than replacing it. Here is what that looks like on a round number.

Example: $10,000 early withdrawal at age 40 (pre-tax money, 22% bracket, no exception): Gross withdrawal $10,000 10% early-withdrawal penalty -$1,000 Federal income tax at 22% -$2,200 Kept after federal tax and penalty $6,800 The plan withholds 20% ($2,000) up front on a rollover-eligible cash distribution; the rest of the tax and the entire penalty are settled on your return. State income tax reduces the take further.

Two things about that example catch people off guard. The 20% withheld at the time of the distribution is only a deposit against your income tax, so it doesn’t cover the penalty at all. And because the withdrawal is added to your other income for the year, a large one can push part of it into a higher bracket than the one you started in.

What are the exceptions to the 10% penalty?

Here is every exception in IRC §72(t) that applies to 401(k) distributions.

Age 59½. The penalty never applies after 59½. See the age 59½ rules.
Rule of 55. Separation from service in or after the calendar year you turn 55 exempts distributions from that employer’s plan; age 50 or 25 years of service for public-safety employees. Detail below.
Death. Distributions to your beneficiary or estate after your death.
Total and permanent disability.
Terminal illness. A physician-certified terminal illness (SECURE 2.0).
Medical expenses over 7.5% of AGI. Penalty-free up to the amount of unreimbursed medical expenses exceeding 7.5% of your adjusted gross income that year. This often pairs with a hardship withdrawal.
QDRO. Distributions to an alternate payee under a qualified domestic relations order in divorce.
SEPP / 72(t) payments. A series of substantially equal periodic payments based on life expectancy, continued for at least 5 years or until 59½, whichever is later. Breaking the series retroactively triggers the penalty on all prior payments.
IRS levy. Amounts the IRS seizes from the plan directly.
Qualified reservist distribution. Reservists called to active duty for 180+ days.
Birth or adoption, up to $5,000. Per parent, per child, within one year of birth or adoption (SECURE Act); repayable to the plan.
Emergency personal expense, up to $1,000 per year. One distribution per year for unforeseeable personal or family emergencies, available since 2024 (SECURE 2.0); repayable within 3 years, and further emergency distributions are restricted until repayment or new contributions match the amount.
Domestic-abuse victim. Up to the lesser of $10,000 (indexed) or 50% of the account (SECURE 2.0).
Federally declared disaster, up to $22,000. Qualified disaster recovery distributions, taxable over 3 years and repayable (SECURE 2.0).

Notice what is not on that list. Hardship is missing, and that surprises almost everyone. A hardship withdrawal is still penalized under 59½ unless one of these separate exceptions happens to apply to the same distribution. Corrective distributions of excess deferrals made by the deadline aren’t subject to the penalty either, though they are a correction rather than a withdrawal you choose.

Exception	401(k), IRA, or both	What it covers and any limit	What you need to claim it
Age 59½	Both	Every distribution on or after the date you turn 59½. No dollar limit and no reason required.	Nothing. The plan or custodian reports it as a normal distribution (Form 1099-R code 7).
Rule of 55	401(k) and other employer plans only. Not IRAs.	Distributions from the plan of the employer you separated from in or after the calendar year you turn 55. Unlimited in amount, but only from that one plan.	Your separation date and the plan’s records. Plans often code the 1099-R as an exception (code 2). If yours codes it 1, claim the exception on Form 5329.
Rule of 55, public-safety version	Employer plans only. Not IRAs.	Same rule at age 50, or after 25 years of service, for qualified public-safety employees such as police, firefighters, and EMS.

Any age, any amount allowed by the order.	The court-issued order, qualified and accepted by the plan administrator. Take the cash before rolling the share to an IRA, or the exception is lost.
SEPP, also called 72(t) payments	Both	A series of substantially equal periodic payments based on life expectancy, continued at least 5 years or until 59½, whichever comes later. Breaking the series retroactively penalizes every earlier payment.	Your calculation and the method you chose, documented at the start and kept for the life of the series. Claimed on Form 5329.

Qualified higher-education expenses	IRA only. Not 401(k) plans.	Tuition, fees, books, supplies, and required equipment for you, your spouse, your children, or your grandchildren.	School billing statements and proof of what scholarships or aid already covered.

Several of the newer SECURE 2.0 distribution types are optional for employer plans, so your plan may simply not offer them even though the law allows them. Your plan document controls what you can request from a 401(k). Income tax is still due on every row in this table. An exception removes the extra 10%, never the ordinary income tax on pre-tax money.

The rule of 55

If you leave your job in or after the calendar year you turn 55, distributions from that employer’s 401(k) are exempt from the 10% penalty (IRC §72(t)(2)(A)(v)). It doesn’t matter whether you quit, were fired, were laid off, or retired on your own terms. These are the pieces that trip people up.

It’s the year you turn 55, not your 55th birthday. Separate in January and turn 55 in December, and every distribution that year and after is exempt.
It covers only the plan of the employer you separated from at 55 or later. Old 401(k)s from jobs you left at 52 stay penalized until 59½.
Public-safety employees (police, firefighters, EMS, certain federal law enforcement) qualify at age 50, or with 25 years of service.
Income tax still applies. The rule kills only the penalty.
Rolling the money to an IRA destroys the exception. See the next section.

401(k)-only penalty exceptions

Two important exceptions live only in employer plans, and both disappear the moment the money lands in an IRA.

Rule of 55. IRAs have no age-55 separation exception. IRA money is penalized until 59½ no matter when you left your job.
QDRO. An alternate payee can take penalty-free cash from a 401(k) under a QDRO at any age. Once that same money sits in an IRA, withdrawals are penalized like any other early IRA distribution.

The practical takeaway is about sequence. If you’re between 55 and 59½ and might need the money, or you’re receiving a QDRO share you plan to spend, take the cash out of the plan before you roll anything over. The comparison cuts both ways, though. IRAs have a few exceptions that 401(k)s lack, notably the first-home purchase and higher-education exceptions in the table above, so neither account type is universally more flexible.

Reporting and paying the penalty

The plan reports your distribution on Form 1099-R, and box 7 carries a code telling the IRS how to treat it. Code 1 means an early distribution with no known exception. Code 2 means early, but an exception applies, which plans commonly use for QDRO and rule-of-55 distributions. Code 7 means a normal distribution after 59½.

A code 1 on your 1099-R is not a verdict. If you qualify for an exception, you don’t owe the penalty, regardless of what the plan coded. You file Form 5329 with your return and enter the exception that fits your situation, and the penalty is calculated there and carried to your Form 1040.

One timing detail causes a lot of April surprises. Employers do not withhold the penalty. The mandatory 20% withholding on a cash distribution covers income tax only, so the 10% arrives as a bill when you file unless you planned for it.

Watch for: The most expensive mistake on this page is paying a penalty you never owed. If your 1099-R shows code 1 but your situation matches any row in the exception table, file Form 5329 and claim it. Tax software will usually ask about exceptions only if you tell it the distribution was early, so don’t skip that screen. If you already filed and paid a penalty you were exempt from, an amended return can generally recover it.

Legitimate ways to avoid the penalty

Several strategies let you reach retirement money without the 10% hit. They’re worth comparing before you take the cash.

Wait for 59½ or, if you separated at 55 or later, use the rule of 55 from that plan.
Borrow instead. A 401(k) loan up to the lesser of $50,000 or 50% of your vested balance is penalty-free and tax-free if repaid on schedule (IRS plan-loan rules under IRC §72(p)).
Match an exception. If your situation fits one (medical bills over 7.5% of AGI, the $1,000 emergency, birth or adoption), document it and claim it on Form 5329.
Don’t roll over money you’ll need before 59½ when the rule of 55 or a QDRO already covers it inside the plan.
Roll over, don’t cash out, when changing jobs. A direct rollover moves the balance with no tax, no withholding, and no penalty. Cashing out “just to move it” is the most common self-inflicted penalty there is.

Frequently asked questions

Is the 10% penalty on top of income taxes?

Yes. An early withdrawal of pre-tax money is taxed as ordinary income, and then the 10% additional tax is added. In a 22% bracket, roughly a third of an early withdrawal goes to federal tax and penalty combined, before any state tax.

Can I avoid the penalty by rolling my 401(k) to an IRA first?

The rollover itself is tax-free and penalty-free, but it doesn’t unlock the money. Early IRA withdrawals face the same 10% penalty. Rolling over can actually make things worse, because it forfeits the two 401(k)-only exceptions. The rule of 55 and the QDRO exception simply don’t exist in IRAs.

Does the penalty apply to Roth 401(k) withdrawals?

It applies to the taxable portion only. A non-qualified Roth 401(k) distribution comes out pro-rata between your contributions and the earnings on them. The earnings share is taxable and, before 59½, subject to the 10% penalty. Qualified Roth distributions, meaning you’re past 59½ and have met the 5-year rule, are both tax-free and penalty-free.

Does my employer withhold the 10% penalty when I cash out?

No. The plan withholds a mandatory 20% for federal income tax on a rollover-eligible cash distribution, and the penalty isn’t included in it. You calculate and pay the 10% with your tax return on Form 5329, which is why the bill surprises so many people at filing time.

What is the age 55 rule for 401(k) withdrawals?

If you separate from service in or after the calendar year you turn 55, withdrawals from that employer’s 401(k) escape the 10% penalty. Public-safety employees qualify at age 50 or with 25 years of service. It applies only to that plan, only after you’ve separated, and it’s lost the moment the money is rolled to an IRA.

Are there penalty exceptions IRAs have that 401(k)s don’t?

Yes. IRAs allow penalty-free early withdrawals of up to $10,000 for a first-home purchase and for qualified higher-education expenses, and 401(k)s don’t. If either one is your situation, money already sitting in an IRA is more flexible than money in a plan.
