The short answer
If you leave your employer during or after the calendar year you turn 55, withdrawals from that employer’s 401(k) or 403(b) are not subject to the 10% early-withdrawal penalty. You still owe income tax. The rule does not apply to IRAs, so rolling the 401(k) into an IRA gives up the exception.
| Account | Penalty-free before 59½ under the Rule of 55? |
|---|---|
| 401(k) or 403(b) at the employer you left at 55+ | Yes |
| 401(k) from an earlier job you left before 55 | No, unless rolled into the current plan before you leave |
| Traditional, rollover, SEP, or SIMPLE IRA | No |
| Governmental 457(b) | No 10% penalty at any age after you leave (separate rule) |

How the Rule of 55 works
Normally, money taken from a 401(k) or IRA before age 59½ is hit with a 10% additional tax on top of income tax. The Rule of 55 is one of the IRS exceptions. Four details decide whether it applies:
- The calendar year, not your birthday. You must separate from service during or after the calendar year you turn 55. Retiring in March of the year you turn 55 qualifies even if your birthday is in December.
- Only the plan of the employer you left. Old 401(k)s from previous jobs do not qualify, unless you moved them into your current employer’s plan before you left.
- Any reason for leaving. Retiring, quitting, being laid off, or being let go all count.
- Your plan must allow the withdrawals. Some plans allow flexible partial withdrawals after you leave; others allow only a single lump sum or a few installment options. Check the plan’s distribution rules before your last day.
You can take a new job afterward. The exception depends on leaving the employer that sponsors the plan, not on staying retired.
Public safety workers: the age 50 version
Qualified public safety employees, such as certain police officers, firefighters, emergency medical workers, and corrections officers in governmental plans, can generally use the same exception if they separate from service in or after the year they turn 50, and in some cases after 25 years of service. Confirm eligibility with your plan administrator.
The rollover trap
Don’t roll it over by reflex
Many people roll their 401(k) into an IRA when they retire, for more investment choice or simpler paperwork. If you are between 55 and 59½ and may need the money, that move can cost you: once the money is in an IRA, withdrawals before 59½ generally face the 10% penalty again.
Ways families handle this (see our full guide to 401(k) rollover options at retirement):
- Leave enough in the 401(k) to cover spending until 59½, and roll the rest to an IRA if the plan allows partial rollovers.
- Consolidate before you leave. If your current plan accepts roll-ins, moving an old 401(k) or a pre-tax IRA into it before your last day can bring that money under the Rule of 55 too.
- Check for company stock first. If the 401(k) holds your employer’s stock, a special tax treatment called net unrealized appreciation (NUA) may be worth evaluating before any rollover.
A worked example
Lisa turns 55 in November and retires in March of the same year. She has $900,000 in her current employer’s 401(k) and $250,000 in a rollover IRA from an earlier job. She plans to spend $90,000 a year from savings until she turns 59½, about four and a half years.
| Where the $90,000 a year comes from | 10% penalty per year | Penalty until 59½ |
|---|---|---|
| Current employer’s 401(k), using the Rule of 55 | $0 | $0 |
| The rollover IRA, or the 401(k) after rolling it to an IRA | $9,000 | about $40,500 |
Hypothetical and simplified for illustration. Income tax applies in both cases; the difference shown is only the 10% additional tax.
Lisa still owes ordinary income tax on each withdrawal, and her plan will generally withhold 20% for federal tax when it pays her directly. The withholding is a prepayment, not an extra tax, and is reconciled when she files. Because she has little other income in these years, she may also be in a lower bracket than she will be once Social Security and required distributions begin, which can make these years a good time for partial Roth conversions from the IRA.
Thinking about retiring before 59½?
Before your last day, we’ll map which accounts to draw from, what to keep in the 401(k), and how to bridge to Social Security with the least tax.
Schedule a call →Rule of 55 vs. other ways to get money before 59½
| Rule of 55 | 72(t) equal payments (SEPP) | Taxable account | |
|---|---|---|---|
| Accounts | Current employer’s 401(k) or 403(b) | IRAs and employer plans | Brokerage and savings |
| Flexibility | Withdraw as needed, if the plan allows | Fixed schedule for 5 years or until 59½, whichever is longer | Fully flexible |
| Main risk | Lost if rolled to an IRA first | Changing the schedule can trigger penalties on all past payments | Capital gains tax on growth |
Many early retirees combine them: Rule of 55 withdrawals for steady spending, a taxable account for flexibility, and IRAs left to grow or converted to Roth in low-income years.
Roth 401(k) money
The Rule of 55 also removes the 10% penalty on Roth 401(k) withdrawals. Your contributions come out tax-free; earnings may be taxable if you have not reached 59½ and met the five-year rule, but the penalty does not apply.
Pennsylvania residents
Pennsylvania generally does not tax payments from an employer retirement plan once you have met the plan’s conditions for retirement and actually retired. If you leave before meeting those conditions, part of a withdrawal can be taxable in Pennsylvania. Pennsylvania also taxes IRA withdrawals taken before 59½ on the amount above your contributions, one more reason to think carefully before rolling the 401(k) into an IRA. See our Pennsylvania retirement tax guide.
Frequently asked questions
What is the Rule of 55?
The Rule of 55 is an IRS exception that lets you take withdrawals from your current employer’s 401(k) or 403(b) without the 10% early-withdrawal penalty if you leave that job during or after the calendar year you turn 55. The withdrawals are still subject to regular income tax. It applies only to the plan of the employer you left, not to IRAs or plans from earlier jobs.
Does the Rule of 55 apply to IRAs?
No. The Rule of 55 applies to employer plans such as 401(k)s and 403(b)s, not to IRAs, SEP IRAs, or SIMPLE IRAs. If you roll your 401(k) into an IRA after leaving your job, withdrawals from the IRA before age 59½ are generally subject to the 10% penalty unless another exception applies.
Do I have to be 55 when I leave my job?
No. You must leave your job during or after the calendar year in which you turn 55. If your 55th birthday is in November and you retire in March of that same year, you still qualify. Leaving at 54 in an earlier calendar year does not qualify, even if you wait until 55 to withdraw.
Can I work after using the Rule of 55?
Yes. The exception depends on separating from the employer that sponsors the plan, not on staying retired. You can take a new job and keep taking penalty-free withdrawals from the old employer’s plan. Your new employer’s plan is a separate plan and does not qualify until you leave that job under the same rules.
Is there a Rule of 50 for public safety workers?
Yes. Qualified public safety employees, such as certain police officers, firefighters, emergency medical workers, and corrections officers in governmental plans, can generally use the exception if they separate from service in or after the year they turn 50, and in some cases after 25 years of service. Check the plan’s rules and confirm eligibility with the plan administrator.
Are Rule of 55 withdrawals taxed?
Yes. The Rule of 55 removes only the 10% penalty. Withdrawals from pre-tax 401(k) money are taxed as ordinary income, and plans generally must withhold 20% for federal tax on lump-sum or partial withdrawals paid to you. Pennsylvania generally does not tax employer plan distributions once you have met the plan’s retirement conditions and retired.
