Your 401(k) is likely the single largest balance you will ever have to move in one transaction. Where it goes next depends on a transfer method most workers never think twice about.
Nearly 6 million Americans rolled funds from workplace plans into individual retirement accounts in 2023, the latest IRS data shows. The combined value topped $682 billion, CNBC reported.
For workers weighing their 401(k) options at separation, the transfer method they select determines whether that balance stays intact or takes an immediate hit.
Fidelity’s rollover guide details the 20% withholding on indirect transfers
Fidelity’s guide separates two transfer methods, drawing a sharp line between a direct rollover that moves money straight to the new IRA provider and an indirect rollover that sends funds to the account holder first.
That second path triggers an automatic 20% federal tax withholding on all taxable amounts. Miss the deadline, and the IRS treats the entire distribution as taxable income with a 10% penalty for anyone under 59½.

A worker rolling over $100,000 through an indirect transfer would receive a check for only $80,000, the guide explains. The other $20,000 goes to the IRS as a provisional tax payment.
To avoid a 10% early withdrawal penalty on that gap, the account holder must cover the $20,000 from personal savings. Filers may recover the withheld amount as a refund, but reimbursement depends on total tax liability, Fidelity notes.
The 60-day deadline that converts a 401(k) rollover into taxable income
Fidelity’s guide flags a second trap which is tied to timing rather than taxes. Once the plan distributes funds through an indirect rollover, the recipient has 60 calendar days to deposit the money into an IRA account.
If the window closes before the deposit is complete, the entire distribution counts as ordinary income on the account holder’s federal return.
Morgan Stanley’s rollover guidance for departing employees describes the same withholding and 60-day mechanics, recommending workers avoid indirect rollovers when possible.
The IRS can waive the deadline in limited circumstances, including disability, serious illness, hospitalization, and financial institution errors.
401(k)-to-IRA rollover volumes are surging as boomers retire
The number of people facing these rollover rules is climbing fast as retirements accelerate and job changes remain elevated across the workforce.
Cerulli Associates projects $941 billion in workplace-plan-to-IRA rollovers this year alone. Annual flows could reach $1.3 trillion by 2031, CNBC reported.
A Pew Charitable Trusts analysis found that the fee gap between retail and workplace mutual fund shares, applied to the $516.7 billion rolled into traditional IRAs in 2018, would reduce aggregate retirement savings by $45.5 billion over 25 years.
More than 11,000 Americans are turning 65 each day in 2026, the Alliance for Lifetime Income estimated.
David Blanchett, a certified financial planner and head of retirement research for Prudential Financial, told CNBC that former 401(k) balances make up the overwhelming share of IRA assets, while direct deposits from savers barely register.
<strong>People by and large don’t save money in IRAs at all</strong>… <strong>All the money in IRAs is coming from rollovers.</strong>
Once the funds land in an IRA, the original employer plan will typically refuse to take them back, Blanchett added.
The CFP Board has cautioned that a 401(k)-to-IRA rollover may be irreversible, making the initial decision one that is difficult to undo.
How Fidelity says direct rollovers eliminate the withholding and deadline
Fidelity’s guide confirms that both the 20% withholding and the 60-day deadline apply only to indirect rollovers. A direct transfer, where the old plan sends money straight to the new IRA custodian, sidesteps both.
With a direct rollover, the account holder never takes possession of the funds. The guide states there is no withholding, no 60-day countdown, and no one-rollover-per-year restriction.
The IRS moved to reduce friction for direct transfers on August 12 by issuing Notice 2026-49 with standardized sample forms under Section 324 of the SECURE 2.0 Act.
Fidelity’s one step to protect your full 401(k) balance
When a worker changes jobs or retires, the plan administrator typically asks how to handle the departure payout. That answer determines whether the full balance transfers intact or shrinks before it even arrives.
The guide also notes that workers who roll over from a Fidelity 401(k) to a Fidelity IRA see an electronic transfer with no check issued.
For rollovers to an outside provider, the firm sends a check payable to that custodian on the worker’s behalf. The money never touches the account holder’s hands, and Fidelity confirmed no tax consequences apply.
