Required minimum distributions force most retirement savers to start pulling money from tax-deferred accounts at age 73, whether the cash is needed or not. One overlooked provision quietly suspends that clock. A worker who stays on the job past 73 can, under the right conditions, postpone withdrawals from that employer’s 401(k) until the year of retirement, keeping the balance invested and untaxed for longer. The exception is narrow and carries a significant ownership catch, which is why it rewards the employees who know it exists and trips up those who assume the deadline is universal.
How the still-working exception actually works
Under the IRS rules governing required minimum distributions, a participant who is still employed by the company sponsoring a workplace plan can generally delay taking distributions from that plan until April 1 of the year after retirement, provided the plan’s own terms allow it. The mechanism applies to the account held with the current employer, letting a still-working employee leave that 401(k) untouched while the standard age-73 trigger passes by.
The age itself has shifted in recent years, which adds to the confusion. Legislation moved the required-distribution age to 73 for those reaching it in 2023 and later, and it is scheduled to rise to 75 for those who turn 74 after 2032. The still-working exception layers on top of whatever the current age happens to be, so a worker tracking the rule needs both the right starting age and the plan-specific deferral, not one without the other.
The catch that disqualifies many is ownership. The exception does not apply to anyone who owns more than five percent of the business sponsoring the plan, a rule aimed at company principals rather than rank-and-file employees. A five-percent owner must begin distributions at 73 regardless of whether work continues, so the same paycheck that lets an ordinary employee defer offers a substantial business owner no relief at all.
Plan permission is the second condition. The exception is available only when the employer’s plan document adopts it, and while most large plans do, a saver cannot assume it applies without confirming the plan’s terms. The provision is a permission the tax code grants, not a mandate every plan must follow, so the deferral lives or dies on the fine print of the specific 401(k) in question.

What the exception does not touch
The relief is strictly limited to the plan at the current job. Money sitting in a traditional IRA, or in a 401(k) left behind at a former employer, remains subject to the ordinary age-73 deadline even while the worker keeps earning. The IRS comparison of IRAs and workplace plans makes the split explicit: still working defers only the active employer’s plan, not the accounts scattered elsewhere.
That boundary points to a common planning move. A worker who wants to maximize the exception can sometimes roll an old 401(k), or even IRA balances, into the current employer’s plan before reaching 73, assuming the plan accepts incoming rollovers, so that the consolidated balance shelters under the still-working umbrella. The strategy depends entirely on plan rules, but it turns a narrow exception into a broader deferral for those positioned to use it.
SEP and SIMPLE IRA participants get no similar break under this rule. The IRS treats those accounts like other IRAs for the still-working question, so retirement savings held through a small-employer arrangement do not qualify for the delay even if the person is clearly still working. The exception is a feature of workplace defined-contribution plans specifically, which means the type of account a saver holds matters as much as whether the paychecks are still arriving.
A parallel change removed workplace Roth accounts from the distribution rules entirely, beginning in 2024, so money in a designated Roth 401(k) no longer forces withdrawals during the owner’s lifetime. That development sits alongside the still-working exception as another way the required-distribution regime has loosened, though the two operate independently: one suspends withdrawals from a current employer’s traditional plan, the other erases the mandate for workplace Roth savings altogether.
The trade-off buried in the deferral
Postponing distributions is not automatically the better financial choice. Every dollar left in a traditional 401(k) keeps growing tax-deferred, but it also remains fully taxable when it eventually comes out, and a large balance drawn down over a shorter retirement can push a worker into a higher bracket later. The still-working exception buys time, yet it can also concentrate taxable withdrawals into fewer years once the job finally ends.
Timing the first distribution compounds the stakes. Retirement in a given year starts the clock, and the first required withdrawal can be delayed only to the following April 1, after which distributions must continue annually. A worker who retires late in a year may find two years of withdrawals landing close together, an outcome that rewards planning the exit date as carefully as the deferral itself.
The exception ultimately favors the employee who treats it as a decision rather than a default. Confirming that the plan adopts the rule, checking that the five-percent ownership line is not crossed, and weighing the eventual tax bill against the years of continued growth are the steps that separate a smart deferral from a postponed problem. For a healthy worker with income from a paycheck, though, the option to leave a 401(k) growing past 73 is a genuine lever the standard rules obscure.
