You can withdraw from a 401(k) without penalty starting at age 59½. Take money out before that, and you’ll typically owe a 10% early withdrawal penalty on top of regular income taxes. But 59½ isn’t the only age that matters. Several other age thresholds affect when you can access your money, when you must start taking it out, and how much you’ll pay in taxes.
Age 59½: The Standard Penalty-Free Threshold
Once you turn 59½, you can take distributions from your 401(k) without triggering the 10% early withdrawal penalty. This applies whether you’re still working or already retired. If you have a traditional 401(k), every dollar you withdraw counts as ordinary income and gets taxed at your federal income tax rate for that year. The penalty disappears at 59½, but the income tax never does for traditional accounts.
If you have a Roth 401(k), the rules are slightly different. Your contributions come out tax-free regardless of age since you already paid taxes on that money. But to withdraw the earnings tax-free, you need to be at least 59½ and the account must have been open for at least five years. If you meet both conditions, the entire withdrawal is tax-free.
Age 55: The Separation-From-Service Exception
You don’t necessarily have to wait until 59½. Under what’s commonly called the “Rule of 55,” you can take penalty-free withdrawals from your 401(k) if you leave your job during or after the calendar year you turn 55. The key requirement is that the withdrawal comes from the plan held by the employer you separated from. Money sitting in an old 401(k) from a previous job doesn’t qualify unless you rolled it into your current employer’s plan before leaving.
This rule applies only to employer-sponsored plans like 401(k)s and 403(b)s. It does not apply to IRAs. So if you roll your 401(k) into an IRA before age 59½, you lose access to the Rule of 55 for that money. If you’re planning to retire in your mid-to-late 50s, it’s worth keeping funds in your employer plan rather than rolling them over prematurely.
For certain public safety employees (firefighters, police officers, EMTs, and similar roles), the age drops even further to 50 under the same separation-from-service rule.
Before Age 55: Exceptions That Avoid the Penalty
Withdrawing before 55 usually means paying the 10% penalty plus income taxes, but several exceptions let you avoid that penalty in specific circumstances:
- Disability: If you become totally and permanently disabled, you can withdraw without the penalty at any age.
- Terminal illness: Distributions made after a physician certifies a terminal illness are penalty-free.
- Substantially equal periodic payments: You can set up a series of roughly equal payments based on your life expectancy. Once you start, you must continue for at least five years or until you reach 59½, whichever comes later.
- Emergency personal expenses: You can take one distribution per calendar year for personal or family emergencies, up to the lesser of $1,000 or your vested balance above $1,000. This provision took effect for distributions made after December 31, 2023.
- Domestic abuse: Victims of domestic abuse by a spouse or partner can withdraw up to the lesser of $10,000 or 50% of the account balance, penalty-free. This also applies to distributions after December 31, 2023.
- Medical expenses: Withdrawals used to pay unreimbursed medical expenses that exceed a certain percentage of your adjusted gross income avoid the penalty.
Even when the penalty is waived, traditional 401(k) withdrawals still count as taxable income. The exception removes the extra 10%, not the underlying tax.
Age 73: When You Must Start Withdrawing
At a certain point, the IRS stops letting you keep money in your traditional 401(k) tax-deferred and requires you to start taking distributions. These are called required minimum distributions, or RMDs. You generally must begin taking RMDs in the year you turn 73.
There’s a small timing grace period for your first RMD: you can delay it until April 1 of the year after you turn 73. But if you use that delay, you’ll end up taking two RMDs in the same calendar year (the delayed first one plus the regular one for that year), which could push you into a higher tax bracket.
One important exception: if you’re still working at 73 and you don’t own 5% or more of the company, you can delay RMDs from your current employer’s 401(k) until the year you actually retire. This doesn’t apply to old 401(k)s from former employers or to traditional IRAs, only the plan at your current job.
Roth 401(k) accounts were previously subject to RMDs, but starting in 2024, Roth 401(k)s are no longer required to take them. If you want to let your Roth 401(k) continue growing, you can leave it untouched.
How Taxes Work at Each Stage
The age you withdraw affects the penalty, but taxes depend on the type of account. With a traditional 401(k), every withdrawal gets added to your taxable income for the year, taxed at your ordinary income tax rate. This is true whether you’re 45, 59½, or 80. The only thing that changes by age is whether the 10% penalty applies on top of that tax.
This makes timing worth thinking about. If you retire at 60 and have several years before Social Security and RMDs kick in, those low-income years can be a window to take 401(k) distributions at a lower tax rate. Once Social Security benefits, RMDs, and any other retirement income stack up, your effective tax rate may be higher than it was right after you stopped working.
Roth 401(k) withdrawals work differently. Since contributions were made with after-tax dollars, you owe nothing on the portion that represents your original contributions. Earnings come out tax-free too, as long as you’re at least 59½ and the account has been open for five years. If you withdraw earnings before meeting both requirements, those earnings are taxable and may also face the 10% penalty.
Quick Reference by Age
- Before 55: Withdrawals face income tax plus a 10% penalty, unless a specific exception applies.
- 55 to 59½: Penalty-free if you left the employer sponsoring the plan during or after the year you turned 55. Otherwise, the 10% penalty still applies.
- 59½ and older: No penalty on any 401(k) withdrawal. Traditional accounts owe income tax; qualified Roth withdrawals are tax-free.
- 73: You must begin taking required minimum distributions from traditional accounts or face a steep excise tax on the amount you should have withdrawn.
