Do you have a ‘forgotten’ 401(k)?
If you do, here’s how to reclaim it
Updated:

Key Insights
- Over 29 million retirement accounts worth $1.65 trillion have been forgotten by workers who changed jobs and didn’t roll over their savings, often leading to fees, limited growth, and loss of control.
- Poor record-keeping, job changes, and outdated contact information cause many to overlook old 401(k)s, which can be transferred into low-interest IRAs without the employee’s knowledge.
- Use tools like the National Registry of Unclaimed Retirement Benefits, contact former employers, check the Department of Labor’s Form 5500 database, or use rollover services to consolidate and reclaim your funds.
Throughout their careers, baby boomers likely had many different jobs, and each of those jobs may have provided a retirement savings account. When the employee moves to a new job, they are usually allowed to take their 401(k) with them.
However, many didn’t. According to a recent estimate from Capitalize, a fintech company that tracks retirement rollovers, over 29 million 401(k) accounts — holding more than $1.65 trillion in assets — are considered “forgotten” or “left behind” by workers who have changed jobs and lost track of their retirement savings.
While switching jobs can bring salary increases, better benefits, or improved work-life balance, many employees neglect to roll over their retirement accounts when they leave a company. The result? Dormant 401(k)s that may underperform, rack up fees, or even be transferred to obscure holding accounts known as “safe harbor IRAs” — often with fewer investment options and higher costs.
How it happens
A 401(k) becomes “forgotten” not because it vanishes, but because of poor record-keeping or lack of awareness. When employees leave a job, it’s not uncommon for them to overlook transferring their retirement savings to a new plan or an IRA. Over time, name changes, address changes, and multiple job switches further complicate the issue.
Adding to the problem, employers may initiate forced rollovers for accounts with less than $5,000. These accounts are transferred into low-interest IRAs if the employee doesn’t provide rollover instructions. In worst-case scenarios, former employees may not even be aware that such a transfer has taken place.
Here’s what typically happens when a 401(k) is abandoned:
- Fees Accumulate: Many legacy plans or default IRAs charge management or administrative fees that slowly erode the account balance.
- Investment Stagnation: Funds may be placed in conservative, low-yield investments by default, limiting growth.
- Loss of Control: Without active management, forgotten accounts might not match the person’s current risk tolerance or retirement timeline.
- Tax Penalties: In rare cases, accounts may be cashed out involuntarily, triggering early withdrawal penalties and tax bills.
