How to Withdraw Money from Your 401(k) Before and After Retirement

You can withdraw from a 401(k) while still working, but most withdrawals before age 59½ trigger a 10% penalty plus income tax

Cashing out a 401(k) means taking money out of the account before your employer closes it or you reach retirement age. The tax cost and penalties depend entirely on your age, how long the money has been in the plan, and which withdrawal method you use. A withdrawal at 45 costs far more than one at 62, and some withdrawal routes avoid the penalty entirely while others do not.

The IRS treats 401(k) money as yours to access, but not penalty-free. If you withdraw before age 59½, you owe income tax on the full amount withdrawn plus a 10% early withdrawal penalty — unless you meet one of the IRS exceptions. After 59½, you owe only income tax, no penalty. After age 73, you must withdraw a minimum amount each year whether you want to or not.

Key Takeaways

• Withdrawals before age 59½ are taxed as ordinary income and hit with a 10% penalty unless you may have access to for an IRS exception like disability, medical hardship, or a loan.
• A 401(k) loan lets you borrow from your own balance without triggering the penalty, but you must repay it within five years or face taxes and penalties on the unpaid balance.
• A Roth conversion moves pre-tax 401(k) money into a Roth IRA, where you pay tax now but can withdraw contributions penalty-free later.
• After age 59½, you can withdraw any amount without penalty, though you still owe income tax on the withdrawal.
• Substantially Equal Periodic Payments (SEPP) let you withdraw before 59½ without penalty if you commit to taking equal amounts for at least five years or until age 59½, whichever is longer.

The 10% penalty and when it applies

Any withdrawal before age 59½ is subject to a 10% early withdrawal penalty on top of ordinary income tax. If you withdraw $10,000 at age 45, you owe 10% ($1,000) as penalty plus income tax on the full $10,000 at your tax bracket. The penalty is calculated on the amount withdrawn, not on gains.

The IRS built in exceptions to this rule. You avoid the 10% penalty if you withdraw because of permanent disability, to pay unreimbursed medical expenses over 7.5% of your adjusted gross income, to pay health insurance premiums after job loss, or to pay an IRS levy. You also avoid it if you take a loan from the plan instead of a withdrawal, or if you use the SEPP method described below. Check your plan document to confirm your employer's 401(k) allows these exceptions — not all plans offer all of them.

Taking a loan from your 401(k) instead of a withdrawal

A 401(k) loan lets you borrow from your own account balance without triggering the 10% penalty. You borrow up to 50% of your vested balance (or $69,000, whichever is less, though this cap changes yearly). You repay the loan through payroll deductions, usually over five years, at an interest rate your plan sets — typically prime rate plus 1% or 2%.

The advantage is clear: no penalty, no immediate tax bill, and you pay interest back to yourself. The catch is that if you leave your job before the loan is repaid, the unpaid balance becomes a taxable withdrawal subject to the 10% penalty if you are under 59½. If you owe $8,000 on a $15,000 loan and quit your job at age 50, that $8,000 is treated as a withdrawal, taxed as income, and hit with the 10% penalty. Your plan document sets the repayment deadline — some give 60 to 90 days, others longer — so check before you borrow.

Substantially Equal Periodic Payments (SEPP)

SEPP is an IRS rule that lets you withdraw from a 401(k) before 59½ without the 10% penalty, as long as you follow strict rules. You must withdraw the same amount every year, calculated using one of three IRS-approved formulas based on your life expectancy and account balance. The withdrawals must continue for at least five years or until you turn 59½, whichever is longer.

If you are 50 and start SEPP, you must continue until age 59½ — a nine-year commitment. If you are 58 and start SEPP, you must continue for five years, until age 63. You still owe income tax on each withdrawal, but the 10% penalty does not apply. Break the schedule — take an extra withdrawal or skip a year — and the IRS retroactively applies the 10% penalty to all withdrawals since you started, plus interest. This is a rigid tool best used with a tax professional to calculate the correct amount.

Roth conversions and penalty-free access to contributions

A Roth conversion moves money from your 401(k) into a Roth IRA. You pay income tax on the amount converted in the year you convert it, but once the money is in the Roth, you can withdraw your contributions (not earnings) at any time without penalty or tax. This is useful if you need access to some of your retirement savings before 59½ but want to avoid the 10% penalty.

The process: you instruct your plan administrator to convert a portion of your 401(k) balance to a Roth IRA. The plan sends you the money or transfers it directly to the Roth. You report the conversion on your tax return and pay tax on it. After the conversion, you can withdraw the amount you converted (your contribution) from the Roth without penalty. Earnings stay locked until 59½ unless you meet an exception. This strategy works best if you have time before you need the money, because the tax bill is due the year of conversion.

Withdrawals after age 59½ and required minimum distributions

Once you turn 59½, you can withdraw any amount from your 401(k) without the 10% penalty. You still owe income tax on the withdrawal at your ordinary tax rate. There is no limit on how much you can withdraw or how often — the plan is yours to access as you choose.

Starting at age 73, the IRS requires you to withdraw a minimum amount each year, called a Required Minimum Distribution (RMD). The amount is calculated by dividing your account balance on December 31 of the prior year by a life expectancy factor the IRS publishes. If you do not take your RMD, you owe a 25% penalty on the amount you failed to withdraw (reduced to 10% if you correct it within two years). You can withdraw more than the RMD, but you must withdraw at least the minimum. If you are still working and your plan allows it, you may be able to delay RMDs until you actually retire.

Taxes owed on a full or partial cash-out

When you withdraw from a 401(k), the plan withholds federal income tax automatically — usually 20% for lump-sum distributions. This withholding is not the final tax bill; it is an estimate. If your tax bracket is higher than 20%, you will owe more when you file. If it is lower, you may get a refund.

You also owe state income tax in most states, though some states do not tax retirement income. Your plan may withhold state tax too, or you may need to pay it when you file your state return. If you withdraw $50,000 and the plan withholds 20% ($10,000), you receive $40,000, but you may owe $15,000 or more in total tax depending on your income and state. The withholding protects you from a large bill at tax time, but it is not a substitute for calculating your actual liability with a tax professional.

Direct rollovers and indirect rollovers

A rollover moves money from your 401(k) to another retirement account — usually an IRA — without triggering taxes or penalties, as long as you follow the rules. A direct rollover means the plan administrator sends the money straight to the receiving IRA. You never touch it, and there is no tax withholding or 60-day deadline. This is the cleanest route.

An indirect rollover means the plan sends you a check. You have 60 days to deposit it into an IRA or another 401(k). The plan withholds 20% for federal tax, so if you roll over $50,000, you receive a check for $40,000. To avoid taxes on the full $50,000, you must deposit the $40,000 plus $10,000 from your own pocket into the IRA within 60 days. If you miss the deadline or do not deposit the full amount, the shortfall is taxed as a withdrawal and hit with the 10% penalty if you are under 59½. Direct rollovers avoid this trap entirely.

Frequently Asked Questions

Can I withdraw from my 401(k) while I still work at the company?

Yes, but most plans allow it only after age 59½ or if you meet an exception like disability or financial hardship. Some plans offer in-service withdrawals to employees over 59½ even if they have not retired. Check your plan document or ask your HR department what withdrawals are allowed while you are employed.

What happens to my 401(k) if I leave my job?

Your balance stays in the plan unless your balance is under $5,000, in which case your employer may force you out. You can leave it there, roll it to an IRA, roll it to your new employer's plan, or withdraw it. If you withdraw before 59½, the 10% penalty applies unless you meet an exception or use a loan or SEPP.

How much tax will I owe on a $100,000 withdrawal?

It depends on your tax bracket and state. The plan withholds 20% ($20,000), but your actual tax bill could be higher or lower. If you are in the 24% federal bracket, you owe $24,000 federal plus state tax. Use a tax calculator or consult a tax professional to estimate your actual liability before you withdraw.

Can I undo a withdrawal or rollover?

You can undo an indirect rollover within 60 days by depositing the money back into an IRA or 401(k). You cannot undo a direct rollover or a withdrawal that was not rolled over. If you made a mistake, act fast and contact your plan administrator or the receiving institution immediately.

What is the difference between a withdrawal and a distribution?

In retirement plan language, they mean the same thing — money coming out of your account. A distribution is the formal term; withdrawal is the everyday term. Both are subject to the same tax rules and penalties.
