34% of Americans May Have Lost Track of Retirement Savings From an Old Job. Some Could Be Missing 401(k) Money Before They Turn 30

Picture a 28-year-old signing up for her third employer’s 401(k) when she remembers she also contributed to a plan at her first job after college. She can’t recall the provider or the balance, and she doesn’t know if she ever got a letter about it. She’s a made-up example. Empower’s new research suggests a lot of real workers are in the same spot.

Empower found that 34% of Americans may have savings from a previous employer’s plan that they’ve lost track of.

Among Gen Z, Empower put that share at 50%, and among Millennials at 45%. Empower’s survey covered 2,005 U.S. adults between July 30 and Aug. 1, 2026.

People said they might have lost track, and the study reports no forfeited accounts. Vested 401(k) money still belongs to the worker. Losing track doesn’t stop an invested account from growing. But it can leave money in investments that no longer fit your needs, with fees you haven’t checked. And every job change can make the search harder.

How a $4,000 Account Slips Off the Radar

Say our 28-year-old left an illustrative $4,000 behind when she quit that first job. Four normal life events can spread out the records:

1. Job changes. Every new employer comes with a new plan, a new login and often a new provider. The old plan still has responsibilities to former employees, including sending required notices, but those messages can easily get overlooked.
2. Moves. Statements, rollover notices and tax forms go to whatever address the plan has on file. People in their 20s move a lot, so those letters may be going to an apartment she left years ago.
3. Recordkeeper switches. Employers change 401(k) providers, merge or get bought. Her account could now be held by a firm she’s never heard of, under a plan name that changed when the company did.
4. Small-balance automatic rollovers. Plans can require former employees to move vested balances of $7,000 or less. If the plan forces a payout of more than $1,000 and the worker gives no instructions, the money must generally go into an IRA opened in the worker’s name. Balances of $1,000 or less can be paid out by check, potentially triggering income taxes and an early-withdrawal penalty.

Finding It Shows What Actually Happened

Her $4,000 could still be in the old 401(k), or it may have moved into an automatic rollover IRA. If it stayed in the plan, market gains could have lifted the balance over the years. An automatic rollover IRA, meanwhile, typically holds conservative investments designed to protect the principal, with fees that can eat into modest returns. She won’t know what happened until she tracks down the account.

The search gets harder the longer she waits. Uncashed payout checks and IRAs left untouched for years can end up with a state unclaimed property office. That puts one more agency between her and her money.

Your Step-by-Step Search for an Old 401(k)

1. Call the former employer’s HR or benefits office. Ask for the plan’s name and its current recordkeeper. Ask whether your balance stayed in the plan, was paid out or was rolled into an IRA, and if it was rolled over, which firm received it.
2. Find old W-2s and statements. Box 12 code D on a W-2 shows you made 401(k) contributions that year. Any old statement lists the recordkeeper and the plan or account number you’ll need.
3. Search the Labor Department’s Retirement Savings Lost and Found database for plans linked to your Social Security number. It can help identify former employers’ retirement plans, but it doesn’t locate IRAs or guarantee that money is still owed to you. Then check the unclaimed property database for every state you’ve lived in.
4. Choose a destination for the funds. You may be able to leave the money where it is, roll it into your current employer’s plan if permitted, or move it into an IRA. Compare investment choices and fees before deciding. If you move money from a 401(k), request a direct rollover to avoid mandatory withholding. When an eligible rollover distribution is paid to you instead, the plan generally must withhold 20%. You have 60 days to roll over the full amount, including the withheld portion, or the amount you don’t replace could be taxed and face an early-withdrawal penalty.

For our 28-year-old, an afternoon of phone calls turns a fuzzy memory into a real number on her balance sheet. Finding that money before she turns 30 gives her a chance to check how it’s invested and keep an eye on it for more than three decades. It’s retirement savings she already earned, back on her radar.
