When a worker leaves a job and decides to move an old 401(k), one seemingly small choice determines whether the Internal Revenue Service takes a fifth of the balance up front. Directing the money straight into an individual retirement account, or into a new employer’s plan, moves the full amount with no tax withheld. Taking the distribution as a check written to the account holder personally triggers mandatory 20% federal withholding — even when the intent is to roll it over the same week. The two paths reach the same destination on paper, but only one keeps the entire balance working the whole time, and the difference can cost a saver real money.
The two ways to move retirement money
The IRS recognizes a few methods for shifting retirement funds. In a direct rollover, the plan administrator sends the payment straight to the receiving IRA or plan; the check, if one is issued, is made payable to the new account rather than to the individual. In a trustee-to-trustee transfer, an IRA custodian moves the money directly to another IRA or plan. Both of these avoid withholding entirely, because the funds never pass through the account holder’s hands.
The third method is the 60-day, or indirect, rollover. Here the distribution is paid to the individual, who then has 60 days to deposit it into an IRA or retirement plan. That option is where the withholding rule bites. The distinction the IRS draws is not about where the money ends up but about who receives the check along the way — and that single procedural detail decides the tax treatment.

Why 20% disappears from a personal check
According to the IRS, a retirement-plan distribution paid to the participant is subject to mandatory withholding of 20%, even if the person fully intends to roll it over later. Withholding does not apply when the amount is rolled directly to another plan or to an IRA, and a check payable to the receiving account is likewise exempt. The 20% is not a tax bill in itself; it is a prepayment sent to the IRS that the saver reconciles at tax time. But the mechanics create a trap for anyone who wants to move the entire balance.
The problem is that to complete a full rollover, the saver has to deposit the whole original amount — including the portion already withheld — within 60 days. Because that withheld 20% is now sitting with the IRS, the money has to come from somewhere else. A person who cannot cover the gap from other savings ends up rolling over only the reduced amount, and the withheld portion is then treated as a taxable distribution. Note that IRA distributions follow a gentler default: they carry 10% withholding, which the account holder can elect out of, and a trustee-to-trustee transfer avoids it altogether.
What the shortfall actually costs
The IRS illustrates the stakes with a worked example. A saver it calls Jordan, age 42, receives a $10,000 eligible rollover distribution from a 401(k), and the employer withholds $2,000. If Jordan rolls over only the $8,000 that arrived and lets the $2,000 go, that $2,000 is reported as taxable income. On top of the income tax, because Jordan is under 59½, the withheld amount is also exposed to the 10% additional tax on early distributions unless an exception applies.
To avoid that outcome, Jordan would have to contribute $2,000 from other sources and roll the full $10,000 into the new account, reporting the entire sum as a nontaxable rollover and the $2,000 as taxes already paid. Do that, and the whole distribution stays tax-free and the early-distribution penalty is avoided; the withheld money comes back as a refund or credit when the return is filed. The example captures the core lesson: the indirect route can be made whole, but only if the saver has spare cash to plug the hole the withholding created, and only within the 60-day window.
The deadline and the details that trip people up
The 60-day clock is strict. A distribution not redeposited within 60 days generally becomes a fully taxable withdrawal, with the early-distribution tax layered on for those under 59½. The IRS can waive the deadline in limited circumstances beyond a person’s control, but relief is not guaranteed and requires action. There is also a separate limit worth knowing: an individual may make only one IRA-to-IRA 60-day rollover in any 12-month period across all of their IRAs, a restriction that does not apply to direct transfers or to plan-to-IRA rollovers.
Required minimum distributions cannot be rolled over at all, which matters for older savers who have reached the age when withdrawals become mandatory. And a plan is required to hand a departing participant a written explanation of rollover options, including the right to a direct transfer, precisely because the choice is easy to get wrong. The practical upshot is that for most people moving a former employer’s 401(k), asking the administrator to send the money directly to the new custodian sidesteps the withholding, the 60-day pressure and the penalty risk in one step. The indirect route remains available, but it converts a routine transfer into a timed financial maneuver — one where forgetting to replace the withheld 20% quietly turns part of a retirement account into a taxable event.
