Rule of 55

Explanation

Normally, withdrawals from a 401(k) before 59½ incur a 10% penalty. The Rule of 55 is an exception: if you separate from service (quit, retire, get laid off or are fired) in or after the calendar year you turn 55, you can take distributions from that employer’s plan without the penalty. Regular income tax still applies.

Details that trip people up:

• Timing is by calendar year. If you turn 55 in November and leave in March of that same year, you qualify. Leaving at 54 the year before does not, even if you wait until 55 to withdraw.
• Only the plan of the employer you separated from. 401(k)s from earlier jobs do not qualify, unless you rolled them into the current plan before leaving. Consolidating old plans into your current one beforehand can widen access.
• IRAs never qualify. Rolling the 401(k) into an IRA after leaving gives up the exception for that money.
• Public safety employees in governmental plans can use age 50 (or 25 years of service) instead.
• Plan rules matter. Some plans allow only a single lump-sum distribution, not periodic withdrawals. Check your plan’s distribution options.
• Distributions eligible for rollover typically have 20% federal withholding, which is a prepayment toward your actual tax, not an extra cost.

You can return to work elsewhere later and still use the exception on the old employer’s plan.

In scenarios, if you retire at 55 or later, the app can treat your final employer’s 401(k) as available without penalty, which can bridge the years until 59½.

Example

You turn 56 this year and retire in June. Your current 401(k) holds $600,000; an IRA from an old job holds $200,000. You need $40,000 a year.

• Withdraw $40,000 from the current 401(k): no 10% penalty. You still owe income tax.
• Penalty avoided: $40,000 × 10% = $4,000 a year
• Withdrawing the same $40,000 from the old IRA would have cost the $4,000 penalty.

Over the 3½ years until 59½, that is about $14,000 of penalties avoided.
