Leaving a job in your mid-fifties raises a common question: can I use my 401(k) now without the early-withdrawal penalty? The IRS exception known as the rule of 55 says yes, with limits that catch people out: it covers the plan of the employer you left, not IRAs, and it only removes the 10% additional tax.
This guide sets out who qualifies, what the rule does and does not change, a worked example, and the public-safety and periodic-payment alternatives. It follows IRS Topic 558 and the Form 5329 instructions.
The "rule of 55" is the common name for an exception to the 10% additional tax on early retirement distributions. The IRS exception covers qualified retirement plan distributions (it does not apply to IRAs) that you receive after separation from service when the separation occurs in or after the year you reach age 55 (age 50 for qualified public safety employees and private sector firefighters) or 25 years of service under the plan, whichever is earlier. In plain terms: leave the employer, and the withdrawals from that employer's plan avoid the 10% additional tax if you separated in or after the year you turn 55.
| Question | Answer |
|---|---|
| Is the 10% additional tax avoided? | Yes, on qualifying distributions from the employer's qualified plan |
| Is the money still taxable income? | Yes: the additional tax applies to the portion that is includible in gross income, so a distribution that is taxable stays taxable |
| Does it apply to IRAs? | No. The exception does not apply to IRAs |
| Which plan? | The plan of the employer you separated from |
Distributions that are not taxable, such as those you roll over to another qualified retirement plan, are not subject to the 10% additional tax either. For IRA rules see IRS Topic 557.
| Scenario | 10% additional tax on a $40,000 withdrawal |
|---|---|
| Leave your employer at 55 and withdraw $40,000 from that employer's 401(k) | $0 (the exception applies); the $40,000 is still taxable income |
| Roll the same account to an IRA, then withdraw $40,000 | $4,000 (10% of $40,000): the exception does not apply to IRAs |
Because the exception depends on where the money sits when you take it out, moving the account before withdrawing can cost you the exception.
For governmental plans, a qualified public safety employee who separated from service during or after the year they attained age 50 or 25 years of service, whichever is earlier, can also avoid the 10% tax. A separate exception covers distributions that are part of a series of substantially equal periodic payments for your life or life expectancy; for employer plans these payments must begin after separation from service (Form 5329 exception 02).
The wording is "in or after the year you reach age 55". That means the calendar year counts, not the birthday: separating in the year you turn 55 qualifies even if you leave before your 55th birthday; leaving in an earlier year does not qualify (IRS Publication 575). Ask your plan administrator how and when the plan pays out after you leave. See our 401(k) limits guide and early retirement tax planning guide.
