Do you trust that your small 401(k) balance would be handled well after a job change?

Vanguard released an analysis finding that automatic 401(k) rollover systems reduced cash-outs of small retirement balances. Only 6% of accounts transferred into IRAs have moved to a new employer's plan as of early 2026.

Why it matters

Cashing out small retirement balances can trigger taxes and a 10% early withdrawal penalty for workers under 59½, eroding long-term savings. Automatic portability aims to keep those funds invested as workers change jobs.

The figures come from Vanguard's analysis of roughly 220,000 outbound rollovers, comparing cash-out rates before and after joining the network. Of the 1.22 million eligible participants awaiting employer matches, only 6% of IRA-held accounts have so far reached new plans.

The players

Vanguard

Vanguard is a major investment management firm that conducted the analysis of automatic 401(k) portability outcomes.

Portability Services Network

The Portability Services Network is a coalition of major 401(k) administrators that launched in November 2023 to automate rollovers of small retirement balances.

The details

Under the Portability Services Network, a coalition of major 401(k) administrators launched in November 2023, departing workers' small balances are automatically rolled into temporary IRAs. Those IRAs hold the funds until the new employer enrolls in the network and a match is made. Current IRS rules bar rolling Roth IRAs into new employer plans, including Roth 401(k)s, and network advocates are pushing for legislation to change that.

Policy Context

Automatic portability works within the existing framework of IRS rollover rules, which currently prevent Roth IRAs from moving into new employer plans, including Roth 401(k)s. Advocates are seeking legislative changes that would allow those transfers and extend the system's benefits to Roth savers.

Workers who change jobs with small 401(k) balances may avoid taxes and penalties if their funds are automatically rolled into a new plan. Those with Roth accounts should note that current rules still prevent Roth transfers into new employer plans.

The takeaway

Check whether your current employer participates in automatic portability before cashing out a small 401(k) balance after leaving a job. Keeping those savings invested can preserve more of your retirement funds over time.
