You packed up your desk, turned in your badge, and started fresh at a different company, but your old 401(k) stayed behind.
The money has not disappeared, yet finding it demands the kind of deliberate effort most workers never get around to completing.
Fidelity Investments, the country’s largest defined contribution plan provider by assets under administration, published a guide that workers can use to track down their forgotten retirement savings.
Dormant retirement accounts have nearly doubled in a decade
The scope of forgotten retirement savings has expanded to levels that financial analysts and retirement researchers now flag as a serious and growing concern.
Department of Labor data tracks accounts left behind in DC plans by workers who moved on under the category “Other Retired or Separated Participants with Vested Right to Benefits.”
Those accounts rose from 14.8 million in 2012 to 28 million in 2023, and could reach 32.8 million by 2026, PensionBee reported in a January 2026 analysis.

As a result, a growing proportion of accounts with a balance are likely not actively managed by the account holder.
In 2012, DOL data showed that 21% of accounts with a balance were dormant. PensionBee estimates that by the end of 2026, that share may exceed 30%.
Fidelity identifies 7 free resources to locate missing 401(k) accounts
Fidelity’s guide, published in April 2026, lays out a practical, step-by-step approach for tracking down retirement savings left with a former employer.
“Ten years ago, one in five accounts was reported to be dormant. This year, that number is much closer to one in three,” said Romi Savova, CEO of PensionBee. “While growing 401(k) participation is a success story, we cannot allow ‘zombie accounts’ to undermine the retirement security of millions.
“These funds often face higher fees and stagnant growth, trapped in plans where they are no longer a priority.”
Fidelity notes that strict Department of Labor rules protect these funds even after you lose track of them, and each of the seven resources listed below is free for workers to use.
Seven places to search for a lost 401(k)
- Your previous employer: Contact the benefits department of the company you left and ask which financial firm handled the 401(k) plan during your time there.
- Your previous plan administrator: Reach out directly to the financial institution that managed the plan, such as Fidelity, Vanguard, or Schwab, if you recall the firm’s name.
- Your state’s unclaimed property database: Every state maintains a free, searchable online database where residents can find and claim financial assets that belong to them.
- The Pension Benefit Guaranty Corporation (PBGC): This federal agency’s search tool can help locate assets left in ended defined benefit or defined contribution plans from private-sector employers.
- The EBSA Abandoned Plan Program: If your former employer or plan administrator is no longer operating, this searchable database from the Department of Labor may hold your account information.
- The EBSA Retirement Savings Lost and Found Database: Launched in December 2024 under the SECURE 2.0 Act, this newer federal tool covers 401(k)s, other defined-contribution plans, and pensions.
- The National Registry of Unclaimed Retirement Benefits: This privately maintained registry at UnclaimedRetirementBenefits.com is updated weekly and covers assets left behind in many types of former-employer retirement accounts.

Federal enforcement has recovered billions in lost retirement benefits since 2017
One of the most significant developments for workers with missing accounts is the federal government’s expanding role in recovering lost retirement benefits.
The Department of Labor’s Employee Benefits Security Administration has played an increasingly important role in tracking down these savings and connecting workers with their money.
The fundamental purpose of any retirement plan under the Employee Retirement Income Security Act is to pay promised benefits, and the Retirement Savings Lost and Found database will be another tool to help plans do so.
EBSA enforcement efforts have recovered more than $7 billion in retirement benefits paid directly to missing participants and beneficiaries since 2017, the Department of Labor reported in 2024.
The Retirement Savings Lost and Found database, created under Section 303 of the SECURE 2.0 Act, represents the first centralized, government-backed effort to address abandoned retirement accounts at a national scale.
What to do after you find an old 401(k) retirement account
Fidelity outlines four basic options that workers face once they track down a forgotten retirement account, each of which carries distinct tax and investment trade-offs worth evaluating carefully.
The first option is to leave the money in the old employer’s plan, which may be reasonable if the plan offers low-cost investment options and a competitive fee structure.
Secondly, rolling the funds into a new employer’s 401(k) can help consolidate workplace retirement savings, though you would be subject to the new plan’s rules and available investment lineup.
The third option is to roll over into an IRA, which lets workers choose a financial institution and invest in any options it offers, potentially a broader set than those available through an employer’s plan.
Cashing out the account is the fourth option, but it carries the steepest financial consequences for workers who are not yet close to retirement age.
One critical detail that many people overlook is that if you opt for an IRA specifically, your rollover money will sit in cash. This means you’ll need to take an additional step to get invested, Fidelity warned.
Inaction could be the costliest 401(k) decision
Employer-paid administrative fees on your account may shift to you once you leave, and investment allocations made years ago may no longer reflect your goals, Fidelity explained in its guide.
The average American changes jobs roughly 12 times over a career, which means the opportunity to leave money behind repeats itself again and again.
For workers who have not checked on every 401(k) tied to a past employer, Fidelity’s guide positions its seven tools as a starting point for reclaiming those savings.
