Automatic Portability Networks Cut 401(k) Cash-Out Rates While Millions Wait for Employer Opt-Ins
When employees leave a job, walking away with a small retirement account balance has long been the path of least resistance for millions of American workers. New research released by Vanguard shows that participation in the Portability Services Network dramatically reduces those premature withdrawals, though logistical bottlenecks continue to leave the vast majority of transferred funds sitting idle in interim accounts rather than reaching new employer plans.
The Bottom Line:
- Among workers with balances under $1,000, the cashing-out rate within 10 months of leaving a job plunged from approximately 50% down to 9% after their employers began participating in the automatic portability system.
- Since the network launched in November 2023, 53,118 completed transactions have successfully transferred $71.3 million in assets from previous employer plans to new ones.
- Despite millions of participants covered across thousands of participating plans, just 6% of accounts transferred into interim safe-harbor IRAs as part of this automatic portability network successfully reached a new employer plan as of early 2026, largely due to few employers having opted in.
How the Portability Services Network Restricts Premature Withdrawals
The financial mechanics of leaving a job often penalize low-balance savers. Typically, balances under $1,000 result in plans cashing out employees and mailing them a check, while amounts between $1,000 and $7,000 are rolled over into an IRA if the former employee takes no action to move it themselves. Cashing out these funds triggers immediate income tax liabilities and a 10% early withdrawal penalty for individuals younger than 59½, and they lose the opportunity for that money to grow over time.
To stem this leakage, major 401(k) administrators—including Vanguard, Fidelity Investments, and Alight Solutions, among others—partnered with Retirement Clearinghouse to launch the Portability Services Network in late 2023. Under this system, departing workers’ small balances are generally automatically rolled into safe-harbor IRAs. The network then matches those interim accounts with the worker’s new employer plan, executing an automatic transfer.
The Vanguard research evaluated roughly 220,000 outbound rollovers across 83 participating employer-sponsored retirement plans. The typical affected saver identified in the data was 31 years old, earned an annual salary of about $20,000, and had maintained tenure with that employer for roughly six months. For this demographic, median balances sat at a modest $200, with nearly three-quarters of accounts holding less than $1,000.
The intervention proved highly effective at stopping immediate cash-outs. For accounts holding between $1,000 and $7,000, the share of workers cashing out dropped from 39% down to 31%. For balances under $1,000, the reduction was far steeper, dropping from roughly 50% to approximately 9%.
The Structural Bottleneck Facing 7.73 Million Plan Participants
Stopping premature cash-outs, however, did not instantly integrate those assets into active workplace plans. The operational catch of the Portability Services Network requires the receiving employer to also participate in the network for the funds to move to the next employer’s plan.
According to data provided by Steve Holman, senior vice president of Portability Services Network strategy and development at Retirement Clearinghouse, 23,787 plans have adopted automatic portability, representing 7.73 million participants. That footprint remains a fraction of the broader market, which encompasses approximately 96 million total participants across workplace retirement plans.
Consequently, just 6% of accounts transferred into IRAs via the network successfully made it to a new employer’s plan as of early 2026. The remaining balances sit in interim safe-harbor IRAs, awaiting a match with another participating employer. Steve Holman noted that 1.22 million eligible participants are currently waiting to be matched with a new employer, a figure that has climbed more than 25% since the beginning of 2026.
Administrative Fees and Roth Tax Complications Threaten Small Balances
While safe-harbor IRAs protect workers from the punitive tax hits of cashing out, they introduce secondary structural frictions. Small balances left in conservative default cash investments often generate earnings insufficient to cover recurring account-level management fees. According to the Vanguard study, this dynamic leaves unmatched balances vulnerable to gradual erosion over time.
A separate regulatory hurdle restricts Roth savings. While traditional pretax 401(k) accounts roll smoothly into traditional IRAs, and Roth 401(k) accounts transition into Roth IRAs, current IRS regulations prohibit rolling a Roth IRA into a new employer’s 401(k) plan. Network administrators are actively lobbying Congress to alter these rules. Holman stated that industry advocates are pushing for future legislation to allow Roth dollars to qualify for auto-portability, emphasizing that current administrative technology is already fully equipped to support it.
Data from a study by Empower, a 401(k) recordkeeper and founding partner of the network, highlights the large amount of fragmented retirement assets. The survey found that 84% of workers have changed employers at least once, 53% have switched three or more times, and 27% have made at least five career moves. This high job mobility leaves younger generations particularly vulnerable to lost savings: 50% of Generation Z respondents and 45% of millennials reported that they may have retirement savings from a previous employer that they’ve lost track of, compared with 30% of Gen X and 14% of baby boomers.
