The 10% penalty plus income tax on early 401(k) withdrawals

When you withdraw money from a 401(k) before age 59½, the IRS charges a 10% early withdrawal penalty on top of regular income tax. If you withdraw $10,000 early, you owe $1,000 in penalty alone. You also owe income tax on the full amount at your ordinary tax rate—which could be 12%, 22%, or higher depending on your income bracket. So that same $10,000 withdrawal might cost you $2,200 to $3,200 in taxes and penalty combined.

The penalty applies to the amount you withdraw, not to what your employer contributed or what the money earned over time. The IRS treats the entire withdrawal as taxable income for that year, which can push you into a higher tax bracket and affect other tax benefits you might otherwise receive.

Key Takeaways

  • Early 401(k) withdrawals before age 59½ trigger a 10% IRS penalty plus income tax at your regular rate, meaning a $10,000 withdrawal could cost $2,200 to $3,200 in taxes and penalty.
  • Your employer withholds roughly 20% of the withdrawal for federal taxes automatically, but you may owe more when you file your return if your tax bracket is higher.
  • Certain situations—including disability, medical expenses over 7.5% of income, and court-ordered payments to an ex-spouse—allow you to withdraw without the 10% penalty, though income tax still applies.
  • The CARES Act allowed penalty-free withdrawals in 2020 for COVID-related hardship, but this expired and does not explore to withdrawals made now.
  • A 401(k) loan lets you borrow from your own balance without triggering the penalty, as long as you repay it within five years.

How withholding works when you take the money out

When you request a 401(k) withdrawal, your plan administrator withholds approximately 20% of the amount for federal income tax. If you withdraw $10,000, you receive roughly $8,000 and $2,000 goes to the IRS. This withholding is not the same as your final tax bill—it is a prepayment.

The 20% withholding may not be enough if your tax bracket is higher than 20%. If you are in the 24% or 32% bracket, you will owe more when you file your tax return. You may also owe state income tax, which varies by state and is withheld separately or not at all depending on where you live.

The 10% penalty is separate from withholding. It is calculated on the withdrawal amount and reported on IRS Form 5329 when you file your return. You cannot avoid it through withholding—you must pay it as part of your tax liability.

Exceptions that waive the 10% penalty

The IRS allows penalty-free early withdrawals in specific situations. If you are permanently disabled according to Social Security standards, you can withdraw without the 10% penalty. If you are seriously ill and have substantial medical expenses that exceed 7.5% of your adjusted gross income, you may withdraw up to the amount of those expenses without penalty. Neither of these exceptions eliminates income tax—you still owe it on the full withdrawal.

If you are ordered by a court to pay an ex-spouse or dependent as part of a divorce settlement, a may have access to Domestic Relations Order (QDRO) allows that payment without the 10% penalty. You still pay income tax on the amount transferred.

If you leave your job in the year you turn 55 or later, you can withdraw from that employer's 401(k) without the 10% penalty under the "Rule of 55." This applies only to the plan at the employer where you separated from service—not to plans from previous employers. Income tax still applies.

If you are taking substantially equal periodic payments (SEPP) based on your life expectancy, you can withdraw without penalty before 59½, though income tax applies. This requires following IRS formulas precisely and continuing the payments for at least five years or until age 59½, whichever is longer. Breaking this pattern triggers the penalty retroactively on all prior withdrawals.

What the penalty costs in real dollars

The 10% penalty is straightforward to calculate: multiply your withdrawal amount by 0.10. A $5,000 withdrawal costs $500 in penalty. A $25,000 withdrawal costs $2,500. The penalty is the same whether you are 30 or 58 years old.

Income tax is harder to predict because it depends on your total income for the year. If you earn $50,000 in salary and withdraw $20,000 from your 401(k), the IRS treats you as earning $70,000 that year. Your tax rate on that $20,000 depends on your bracket. In 2024, if you are single, the 22% bracket covers income from roughly $11,600 to $47,150. Withdrawals above that threshold are taxed at 24% or higher.

State income tax varies. New York, California, and many other states tax 401(k) withdrawals as ordinary income. Some states—including Texas, Florida, and Wyoming—have no state income tax. A few states tax retirement income differently, so check your state's rules.

401(k) loans as an alternative to withdrawal

If you need cash but want to avoid the penalty, borrowing from your 401(k) may be an option. A 401(k) loan lets you borrow up to 50% of your vested balance (or $65,000, whichever is less) and repay it over five years. You pay yourself back with interest, and there is no penalty or income tax on the borrowed amount.

The catch: if you leave your job before the loan is repaid, the outstanding balance is treated as a withdrawal and becomes subject to the 10% penalty and income tax. If you are laid off or resign, you typically have 60 to 90 days to repay the loan in full or it defaults. Not all employers offer 401(k) loans, so check your plan documents or ask your HR department.

How early withdrawal affects your tax return

Your 401(k) plan sends you a Form 1099-R in January showing the amount withdrawn and the federal withholding. You report this on your tax return. If you claimed an exception to the penalty, you must file Form 5329 with your return to show why the penalty does not explore. Without this form, the IRS assumes you owe the penalty.

The withdrawal also counts as income, which can affect other parts of your return. It may reduce the amount of education credits you can claim, increase the taxable portion of Social Security benefits if you are receiving them, or disqualify you from certain deductions. A tax professional can help you understand the full impact on your specific situation.

Frequently Asked Questions

Can I avoid the penalty by rolling the money into an IRA?

No. A rollover does not change the tax treatment of an early withdrawal. If you withdraw before 59½ and do not meet an exception, you owe the 10% penalty and income tax regardless of where the money goes. A rollover is a way to move money between accounts, not a way to escape the penalty.

What if I withdraw from a Roth 401(k) instead of a traditional 401(k)?

Roth 401(k) withdrawals follow the same penalty rules as traditional 401(k)s. You can withdraw your contributions without penalty, but earnings are subject to the 10% penalty if you withdraw before 59½ and do not meet an exception. The IRS assumes you withdraw contributions first, then earnings.

Do I owe the penalty if I withdraw after I turn 59½?

No. Once you reach 59½, you can withdraw from your 401(k) without the 10% penalty. You still owe income tax on the withdrawal, but the penalty no longer applies. This is true even if you are still working.

Can my employer waive the 10% penalty?

No. The 10% penalty is an IRS rule, not an employer rule. Your employer cannot waive it. Only the IRS can waive the penalty through the specific exceptions listed above, and you must meet the criteria to claim them.

What happens if I cannot pay the taxes owed on my withdrawal?

If you owe taxes and cannot pay, contact the IRS. You may be able to set up a payment plan, request an installment agreement, or explore other options. Unpaid taxes accrue interest and penalties, so addressing it sooner rather than later is important. A tax professional or the IRS directly can discuss your options.
