The rule of 55: early 401(k) withdrawals without the penalty

Updated September 28, 2026 · Checked against official sources

Normally, taking money out of a 401(k) before age 59½ costs a 10% penalty on top of income tax. The rule of 55 is an IRS exception: if you leave your job in or after the calendar year you turn 55, you can withdraw from that employer's plan without the penalty.

How the rule of 55 works

Withdrawals from a 401(k) before 59½ usually face a 10% additional tax on top of regular income tax. The IRS lists several exceptions. One of them covers money paid to you after you separate from service in or after the year you turn 55.

“Separate from service” just means you stopped working for that employer, for any reason: you retired, quit, or were laid off.

Example: Maria turns 55 in 2026 and retires in June. She can withdraw from her current employer’s 401(k) right away without the 10% penalty. She’ll still owe income tax on what she takes out.

What the rule of 55 does not cover

IRAs. Traditional IRAs, SEP IRAs and SIMPLE IRAs don’t have this exception.
Old 401(k)s from employers you left before the year you turned 55.
Money you roll into an IRA. Once it’s in an IRA, the IRA rules apply, so wait to roll over any money you plan to use before 59½.
Income tax. Only the penalty is waived. Withdrawals from a traditional 401(k) are taxed as ordinary income.

Things to check before you rely on it

Your plan’s withdrawal options. Some plans only allow one lump-sum withdrawal, which could push you into a high tax bracket. Ask your plan administrator whether you can take partial or regular payments.
Tax withholding. Plans usually withhold 20% for federal income tax on withdrawals paid to you. You settle up when you file your return.
Your timing. Leaving in December of the year before you turn 55 doesn’t qualify. Leaving in January of the year you turn 55 does.

Other ways to reach your money before 59½

Roth IRA contributions (not earnings) can be withdrawn at any time, tax- and penalty-free.
Taxable brokerage accounts have no age rules at all.
Substantially equal periodic payments (72(t)) let you take a fixed series of payments from an IRA without the penalty. The rules are strict, so get advice first.
Governmental 457(b) plans don’t have the 10% early withdrawal penalty.

Planning to retire at 55?

The rule of 55 solves one problem: getting to your money. You’ll still need enough saved to last 35 years or more, and a plan for health insurance until Medicare at 65.

Frequently asked questions

Do I have to be 55 when I leave my job?

No, you have to leave in or after the calendar year you turn 55. If you turn 55 in December and leave your job in March of that year, you still qualify.

Does the rule of 55 apply to IRAs?

No. The separation-from-service exception only applies to employer plans like 401(k)s and 403(b)s. IRAs generally charge the 10% additional tax on withdrawals before 59½, unless another exception applies.

Can I use the rule of 55 on a 401(k) from an old job?

Not directly. It only covers the plan of the employer you leave at 55 or later. If your current plan accepts roll-ins, moving an old 401(k) into it before you leave can make that money eligible too. Check with your plan first.

Can I go back to work after using the rule of 55?

Yes. Once you've left the employer in or after the year you turn 55, you can keep taking penalty-free withdrawals from that plan even if you take a new job.

Are there exceptions for police and firefighters?

Yes. Qualified public safety employees, such as police officers, firefighters and certain federal law enforcement officers, can use the same exception from age 50 for their workplace plan.
