To find old retirement accounts, start with three free databases keyed to your Social Security number: the Department of Labor’s Retirement Savings Lost and Found at lostandfound.dol.gov, the Pension Benefit Guaranty Corporation’s unclaimed benefits search at pbgc.gov, and MissingMoney.com for state-held funds. Between them, they cover most of the places a forgotten 401(k) or pension can end up. If those don’t turn anything up, you move to direct contact with former employers and, when a company no longer exists, to the DOL’s Abandoned Plan Search. Every step is free.
What to Gather Before You Search
Plan administrators identify accounts by Social Security number first, so that’s the anchor. Note every legal name you used while employed, including maiden names and prior legal names, because your account may still be filed under one you no longer use.
You’ll also want the formal legal name of each former employer (often different from the storefront or brand name) and the approximate start and end dates of each job. An old W-2 or 1099-R is the easiest place to find the legal employer name and Employer Identification Number, and it often lists the retirement plan or the financial institution holding the funds.
If you don’t have those forms, request wage and income transcripts through your IRS online account at IRS.gov or by calling 800-908-9946.1Internal Revenue Service.

The Retirement Savings Lost and Found Database
The Department of Labor’s Retirement Savings Lost and Found, created by the SECURE 2.0 Act of 2022, is the single most direct tool. It’s free at lostandfound.dol.gov and draws from Form 5500 filings and IRS records to show plans linked to your Social Security number, along with contact information for the administrators who can pay you.3U.S. Department of Labor. Retirement Savings Lost and Found Database
Access requires a Login.gov account with identity verification. You’ll need your legal name, date of birth, Social Security number, a mobile device, and a photo of a current driver’s license. Once verified, you enter your Social Security number and the system returns a list of plans; from there, you contact each administrator directly to confirm the balance and start the claims process.
The PBGC Unclaimed Benefits Search
The Pension Benefit Guaranty Corporation is a federal agency that insures private-sector pension plans. If a former employer’s plan was terminated and they lost track of you, the PBGC may be holding your money. Search at pbgc.gov using your last name and the last four digits of your Social Security number.4Pension Benefit Guaranty Corporation. Find Unclaimed Retirement Benefits
The database covers traditional defined-benefit pensions and, through a newer voluntary program, defined-contribution plans like 401(k)s whose sponsors chose to transfer unclaimed balances to the PBGC.5Pension Benefit Guaranty Corporation. Missing Participants Program for Defined Contribution Plans
The National Registry of Unclaimed Retirement Benefits
The National Registry of Unclaimed Retirement Benefits is a private clearinghouse where employers can list former employees with unpaid balances. You enter your Social Security number to check whether any past employer has flagged you as missing.6Pension Benefit Guaranty Corporation. External Resources for Locating Benefits It’s most useful when a company has gone through administrative changes and lost contact with former staff.
State Unclaimed Property Programs
Retirement assets that sit unclaimed for an extended period, usually three to five years, can be transferred to a state government through escheatment.7U.S. Securities and Exchange Commission. Escheatment by Financial Institutions Once that happens, the state treasurer holds the money until the owner or heirs claim it. The funds may go to the state where the employer was headquartered, where you last lived, or where the financial institution is located, so check all of them.
MissingMoney.com, run by the National Association of Unclaimed Property Administrators, aggregates records from most state programs and lets you search several at once for free.8National Association of Unclaimed Property Administrators. National Association of Unclaimed Property Administrators Search under your current legal name and any prior names in every relevant state. Because MissingMoney.com doesn’t yet include every state, also check the treasurer’s website for any state it misses.
One advantage here: state programs don’t deduct fees from the money they hold, so you get the full amount that was originally transferred.9U.S. Department of Labor. Field Assistance Bulletin No. 2025-01 To file a claim you’ll typically need a government-issued photo ID, your Social Security number, and proof of your connection to the address or employer on record. Some states require a notarized form. The claim itself is free.
Contacting the Employer Directly
If you already know where you worked and the company is still in business, a direct call to human resources or the benefits department is often the fastest route. Ask for the status of any retirement account tied to your Social Security number and request a copy of the Summary Plan Description, which lists the third-party administrator — the financial firm that actually manages the account. Many companies outsource 401(k) administration, and HR can point you to the right institution.
When you reach the administrator, ask for a current balance statement and the vesting schedule, which determines how much of the employer’s contributions you get to keep based on your years of service. Give them updated contact information so future tax documents and distribution notices reach you.
If the employer is unresponsive or vague, look up the plan yourself. Every plan administrator files an annual Form 5500 with the Department of Labor, searchable free through the EFAST2 system at efast.dol.gov.10U.S. Department of Labor. EFAST2 Filing – Welcome Search by employer name to find the plan’s trustee, the administrator’s contact details, and the plan’s current status.
When the Company No Longer Exists
Federal law generally requires retirement plan assets to be held in a trust separate from the company’s own finances, so even if the business failed, the money is typically protected from company creditors. The route to it depends on what happened to the employer.
Abandoned Plans
When a company goes out of business without formally winding down its retirement plan, the DOL can designate the plan as “abandoned” and appoint a Qualified Termination Administrator, usually a bank or financial institution, to distribute the assets. Search by employer name or plan name through the DOL’s Abandoned Plan Search at askebsa.dol.gov; results include the QTA’s name and phone number.11U.S. Department of Labor. Abandoned Plan Search DOL regulations preserve the liability of the original plan fiduciaries for any prior mismanagement, so your rights as a participant remain protected after a QTA takes over.12eCFR. 29 CFR Part 2578 – Rules and Regulations for Abandoned Plans
Mergers and Acquisitions
When one company buys another, the acquirer usually takes over the retirement plan or merges it into its own. The task is identifying the successor. The SEC’s EDGAR database at sec.gov/edgar provides free public access to proxy statements and registration documents that detail which entity assumed benefit obligations.13U.S. Securities and Exchange Commission. Using EDGAR to Research Investments State Secretary of State records can also show whether a corporation has dissolved or changed its registered agent. Once you find the successor, contact its HR department as you would any current employer.
Bankruptcy
If a company entered Chapter 7 or Chapter 11, court records usually show what happened to the benefit plans. In many cases the retirement trust survived intact and was transferred to a successor plan, distributed to participants, or turned over to the PBGC. The PBGC database and the DOL’s Abandoned Plan Search cover the most common outcomes.
Small Balances You May Not Realize Were Moved
If you left a job with a small 401(k), your former employer may have moved the money out of the plan without asking, and that’s legal under certain conditions. Under the SECURE 2.0 Act, plan sponsors can distribute a former employee’s vested balance without additional consent if it’s $7,000 or less. Balances of $1,000 or less can be paid out as cash (with taxes withheld). Balances between $1,000 and $7,000 must be automatically rolled into an IRA on your behalf.9U.S. Department of Labor. Field Assistance Bulletin No. 2025-01
These automatic rollover IRAs are often opened at institutions you’ve never heard of, and statements may be mailed to an old address. A 2014 Government Accountability Office study found that fees on small default IRAs frequently outpace investment returns, shrinking the balance over time.9U.S. Department of Labor. Field Assistance Bulletin No. 2025-01 If you suspect a former employer force-rolled your balance, call their HR department to find out which IRA provider received the funds, then contact that provider to reclaim or transfer the account.
Getting the Money Without a Tax Bill
Finding the account is only half of it. How you move the money determines whether you keep the full amount or lose a chunk to taxes and penalties.
The cleanest option is a direct rollover, also called a trustee-to-trustee transfer, where the old plan sends the money straight to your current 401(k) or IRA. No taxes are withheld and no taxable event occurs.14Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Ask the administrator to make the check payable to your new account’s custodian, not to you personally.
If the distribution goes to you instead, the administrator must withhold 20% for federal income taxes, even if you plan to roll it over. You then have 60 days to deposit the full original amount into another qualified retirement account, making up the withheld 20% out of pocket. Miss the deadline and the entire distribution becomes taxable income, plus a 10% additional federal tax if you’re under 59½.15Internal Revenue Service. Topic No. 558, Additional Tax on Early Distributions From Retirement Plans Other Than IRAs A direct rollover avoids both the withholding and the penalty.
Searching as a Beneficiary or Heir
If a family member has died and you believe they had an unclaimed retirement account, most of the tools above are available to you. The PBGC’s database specifically covers participants, beneficiaries, and alternate payees who may be owed benefits from terminated plans.4Pension Benefit Guaranty Corporation. Find Unclaimed Retirement Benefits The Retirement Savings Lost and Found, MissingMoney.com, and the Abandoned Plan Search all accept claims from heirs.
To claim as a beneficiary or heir, you’ll generally need a certified copy of the death certificate, proof of your identity, and documentation establishing your legal right to the funds, such as a beneficiary designation form on file with the plan, a court-issued letter testamentary or letter of administration, or the relevant section of the will. Each administrator sets its own process, so contact them early to learn what they require.
Skip the Paid Recovery Firms
Every database and search tool covered here is free. You don’t need to hire a recovery firm or “heir finder” to locate your retirement money. Companies that contact you unsolicited offering to find your unclaimed property typically charge a percentage of the recovered amount, often 10% or more depending on the state. Many states cap these fees by law, but the caps vary widely and some states impose no maximum. Before you agree to pay anyone, try the free searches yourself: the Retirement Savings Lost and Found, PBGC, MissingMoney.com, and your former employer’s HR department will handle most situations at no cost.
