What Is the 'Still Working' Exception to 401(k) Required Distributions?
Reaching the age when retirement accounts typically require withdrawals doesn’t automatically mean every account has to start paying out right away.
The short answer
The still-working exception allows someone who is past the age that normally triggers required minimum distributions to delay those distributions from their current employer’s 401(k) as long as they remain employed there and don’t own a significant stake in the company. It applies only to the active employer’s plan, not to accounts left behind at previous employers.
How the exception works
Ordinarily, once someone reaches the age the government sets for triggering required distributions, retirement accounts must begin paying out a minimum amount each year whether or not the money is needed. The still-working exception carves out an allowance for a current employer’s 401(k): if the plan permits it and the participant is still actively employed there past that age, the required beginning date for those distributions can be pushed back until the year after employment actually ends. Not every plan offers this exception, so it’s worth confirming with the specific plan whether it applies before assuming distributions can be delayed.
The ownership threshold that disqualifies it
The exception generally doesn’t apply to anyone who owns more than a small ownership stake, commonly described as a five percent or greater interest, in the company sponsoring the plan. Someone who meets that ownership threshold is typically required to begin distributions at the standard age regardless of whether they’re still working, since the exception is designed for employees rather than owners with substantial control over the business. Because ownership percentages and family attribution rules can be technical, this is an area where the actual threshold and how it’s calculated depend on the specific plan and the individual’s situation.
Why it doesn’t extend to old employer accounts
The still-working exception is specific to the plan of the employer someone is currently working for; it doesn’t apply to a 401(k) left behind at a previous job, even if that account still exists untouched. Those older accounts remain subject to the standard required distribution timeline regardless of current employment status, which is one reason some people choose to consolidate old accounts through a 401(k) rollover into their current employer’s plan, if the plan accepts incoming rollovers, so the still-working exception can cover a larger share of their retirement savings.
How it fits into broader retirement timing
For someone weighing when to fully retire, the still-working exception is one more variable to factor in alongside income needs, other account balances, and overall tax planning, since it can affect how much taxable income shows up in a given year while still employed. It doesn’t apply to IRAs or to accounts outside the current employer’s plan, so someone with several different account types may still face required distributions from some accounts even while this exception delays them for others.
What to weigh
Because rules around required distributions and the still-working exception can change and depend heavily on individual circumstances like ownership percentage and specific plan provisions, this is an area where checking directly with a plan administrator, rather than assuming a general rule applies, tends to prevent costly missteps. The exception can be a useful timing tool for someone working later in life, but it has real limits worth understanding upfront.
The takeaway
The still-working exception can delay required distributions from a current employer’s 401(k) for those who keep working past the usual triggering age, but it comes with an ownership cap and doesn’t reach accounts from prior employers. Confirming the specific plan’s rules and understanding how ownership status is measured are the practical first steps before relying on it.
