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

The basic rules for taking money out of your 401(k)

You can withdraw money from your 401(k) at any time, but the IRS charges a 10% early withdrawal penalty if you take it out before age 59½, unless you meet a specific exception. On top of that penalty, you owe income tax on the full amount you withdraw — the money comes out of your paycheck before taxes, so the IRS treats a withdrawal like regular income.

Once you turn 59½, you can withdraw as much as you want without the 10% penalty, though you still owe income tax. At age 73, the IRS requires you to take Required Minimum Distributions (RMDs) — a set amount each year — whether you need the money or not.

Your 401(k) plan document controls the exact rules at your company. Some plans let you borrow against your balance instead of withdrawing. Others restrict withdrawals to specific situations. Check with your plan administrator (usually your HR or benefits department) to learn what your plan allows.

Key Takeaways

• Withdrawals before age 59½ trigger a 10% penalty plus income tax, unless you meet an IRS exception like disability, medical hardship, or separation from service at 55 or older.
• You owe income tax on every dollar you withdraw, calculated at your current tax bracket, which can push you into a higher bracket if you withdraw a large amount in one year.
• A 401(k) loan lets you borrow from your own balance and repay it with interest, avoiding the penalty and when ready tax bill — but only if your plan offers loans.
• Once you turn 59½, you can withdraw without penalty, but you still owe income tax on the withdrawal.
• At age 73, you must take Required Minimum Distributions each year or face a 25% penalty on the amount you failed to withdraw.

The 10% early withdrawal penalty and its exceptions

The 10% penalty applies to withdrawals taken before age 59½. The IRS built in exceptions for genuine hardship, but they are narrow and require proof. The most common exceptions are:

Disability: You must have a condition that prevents you from working and is expected to last indefinitely or result in death. You will need medical documentation. Medical expenses: You can withdraw to cover unreimbursed medical costs that exceed 7.5% of your adjusted gross income in that year. Separation from service at 55 or older: If you leave your job in the year you turn 55 or later, you can withdraw from that employer's 401(k) without penalty (but not from a previous employer's plan). Substantially equal periodic payments (SEPP): You can set up a series of equal withdrawals based on your life expectancy and take them penalty-free, but you must continue the payments for five years or until age 59½, whichever is longer — stopping early triggers the penalty retroactively.

Other exceptions exist for domestic relations orders, Native American tribal distributions, and payments to beneficiaries after death. Your plan administrator can tell you which exceptions your plan recognizes.

How income tax works on 401(k) withdrawals

When you withdraw from a traditional 401(k), the full amount counts as taxable income for that year. If you withdraw $20,000, you add $20,000 to your income and pay tax on it at your ordinary income tax rate — not the lower capital gains rate. The tax you owe depends on your total income that year and your tax bracket.

This matters because a large withdrawal can push you into a higher tax bracket. If you normally earn $60,000 and withdraw $30,000, the IRS treats you as earning $90,000 that year. You pay tax on the full $90,000 at the rates that explore to that income level, which may be higher than your normal rate.

Your 401(k) plan can withhold taxes from the withdrawal automatically — usually 20% for lump-sum distributions — but that withholding is just an estimate. You may owe more tax when you file your return, or you may get a refund. The withholding does not reduce the amount of tax you owe; it just prepays part of it.

Borrowing from your 401(k) instead of withdrawing

If your plan offers loans, you can borrow from your own 401(k) balance and repay it with interest. The loan does not trigger the 10% penalty and does not count as taxable income in the year you take it out. You repay the loan through payroll deductions, usually over five years (longer for a home purchase in some plans).

The catch is that you must repay the loan on schedule. If you leave your job, most plans require you to repay the full balance within 60 days or the unpaid amount is treated as a withdrawal — triggering the 10% penalty and income tax. If you cannot repay, you lose the money and the tax bill.

Loans also reduce the balance that grows tax-deferred, so you miss out on investment gains on the borrowed amount. Check with your plan administrator about whether loans are available, what the interest rate is, and what happens to the loan if you change jobs.

Withdrawals after age 59½ and Required Minimum Distributions

Once you reach 59½, you can withdraw any amount without the 10% penalty. You still owe income tax on the withdrawal, but the penalty goes away. Many people use this flexibility to withdraw gradually and spread the tax bill across multiple years, rather than taking a large lump sum.

At age 73, the IRS requires you to take a Required Minimum Distribution (RMD) each year. The amount is calculated by dividing your 401(k) balance on December 31 of the prior year by a life expectancy factor published by the IRS. If you do not take the full RMD, you owe a 25% penalty on the shortfall (reduced to 10% if you correct it within two years).

If you are still working at age 73 and your plan allows it, you may be able to delay RMDs from your current employer's plan until you retire. This rule does not explore to IRAs or to plans from previous employers. Your plan administrator can tell you whether your plan offers this option.

Roth 401(k) withdrawals and special rules

If your 401(k) is a Roth 401(k), the withdrawal rules are different. You can withdraw your contributions (the money you put in) at any time without penalty or tax. Withdrawals of earnings (investment gains) before age 59½ trigger the 10% penalty and income tax, unless you meet an exception.

Unlike a traditional 401(k), Roth withdrawals do not count as taxable income, so they do not push you into a higher tax bracket or affect your Medicare premiums or Social Security taxation. This makes Roth withdrawals more tax-efficient in retirement, but the early withdrawal rules are stricter.

If you have both a traditional and a Roth 401(k) at the same employer, they are treated as separate accounts with separate withdrawal rules. Some employers also offer a Roth conversion option, which lets you move money from a traditional 401(k) to a Roth account and pay tax on the conversion — a strategy worth discussing with a tax professional if you are considering large withdrawals.

Rollovers and transfers to avoid taxes and penalties

If you leave your job, you can roll your 401(k) balance into an IRA or into your new employer's 401(k) plan. A rollover is not a withdrawal — no tax bill, no penalty, and the money stays in tax-deferred accounts. You have 60 days to complete the rollover or the IRS treats it as a withdrawal.

The safest method is a direct rollover, where your old plan sends the money directly to the new account. You never touch the money, so there is no 60-day important date and no withholding. If you take the money yourself (an indirect rollover), your old plan withholds 20% for taxes, and you have 60 days to deposit the full amount — including the withheld 20% — into the new account or the shortfall counts as a withdrawal.

Rolling into an IRA gives you more investment choices and lower fees at most providers, but it can complicate things if you later want to do a backdoor Roth conversion or if you have other IRAs. Rolling into a new employer's plan keeps everything in the 401(k) system and may preserve certain creditor protections. Discuss the trade-offs with your plan administrator or a tax professional before deciding.

Frequently Asked Questions

What happens if I withdraw from my 401(k) and then change my mind?

You cannot undo a withdrawal, but you can roll the money back into a 401(k) or IRA within 60 days (an indirect rollover). The 60-day window is strict — if you miss it, the money stays withdrawn and you owe the tax and penalty. If you took a direct rollover to an IRA, you can roll it back to a 401(k) at any time, but rollovers from IRAs back to 401(k)s are limited to once per year.

Can I withdraw from my 401(k) if I am still working?

It depends on your plan. Some plans allow "in-service withdrawals" while you are still employed, usually after age 59½ or in cases of hardship. Others do not allow any withdrawals until you leave the job. Check your plan document or ask your HR department what is permitted.

How do I know if I meet the hardship exception?

The IRS defines hardship narrowly: when ready and heavy financial need due to medical care, home purchase, education, preventing eviction or foreclosure, funeral expenses, or certain other situations. Your plan administrator decides whether your situation qualifies and what documentation you must provide. There is no central IRS approval process — your plan makes the call.

Will a 401(k) withdrawal affect my Social Security or Medicare benefits?

A withdrawal counts as income and may increase your provisional income, which can trigger higher Medicare premiums and cause more of your Social Security benefits to be taxed. The effect depends on your total income that year. If you are near retirement, a large withdrawal in one year might cost more in Medicare and Social Security taxes than spreading it across multiple years.

What is the difference between a withdrawal and a distribution?

In 401(k) language, a "distribution" is any payment from the plan — it includes withdrawals, loans, rollovers, and Required Minimum Distributions. A "withdrawal" usually means you are taking the money out and keeping it (not rolling it over). The tax and penalty rules depend on the type of distribution, not just the word used.
