The Orphaned 401(k): Retirement Accounts Physicians Leave at Past Jobs

You've got a login somewhere for the 403(b) from residency. There's a 401(k) at the hospital where you did fellowship. There's probably a third account from the first attending job, the one you took and left after two years. You know roughly what's in each. You couldn't tell your spouse the balances tonight without going and looking them up.

That's normal. Medicine moves you: match, then fellowship, then the job that turned out to be wrong, then the one that stuck. Every move leaves an account behind, under a different recordkeeper, behind a different password. By your fifth year as an attending you may be carrying four retirement accounts, plus a governmental 457(b) that runs on its own rulebook and a 403(b) that never quite behaved like your spouse's 401(k).

Moving an old account isn't complicated. What makes it a physician question is one detail that general rollover advice tends to skip: rolling pre-tax money into a traditional Individual Retirement Account (IRA) may create a tax problem for the backdoor Roth contribution you make every year. Four options exist for every orphaned account, and that one detail changes how they compare.

The Internal Revenue Service sets out the mechanics in its guidance on rollovers of retirement plan and Individual Retirement Account distributions. The rules themselves are short. Applying them to a household with a high marginal tax rate, an annual backdoor Roth, and money parked in three states is where the actual work sits.

Four Jobs, Four Recordkeepers, and No Running Total

The scattering isn't a savings problem. You saved. It's a coordination problem, and it shows up in a few specific ways.

The first is that nobody, including you, can see the whole picture. If your residency 403(b) sits in a target-date fund and your current plan sits in something more aggressive, your household's mix of stocks and bonds is whatever those accounts happen to add up to. That may not be a decision you made. It may be a thing that happened to you across four hiring packets.

The second is administrative drift. Recordkeepers get acquired. Plans merge. A former employer changes payroll vendors and the login you saved in 2019 stops resolving. Mail goes to an address you left two moves ago. None of that touches the money. It just makes the money harder to reach when you finally want it.

The Government Accountability Office has studied this pattern more than once. In its 2024 review of the tax notices plans send to departing employees, it reported that many people have trouble tracking their 401(k) accounts when they change jobs, and that the notices explaining the distribution choices are often hard for participants to use. The thick envelope a former employer's plan mails you is the document that report is about.

The third is force-outs. Plans are permitted to move small balances out on their own after you leave. Depending on the balance and the plan's written terms, that can mean an automatic rollover into a default Individual Retirement Account the plan selects, or a check mailed to your last known address. If you left a residency plan with a small balance and never updated your address, the money may not be where you think it is.

Tracking Down an Account You Can No Longer Log Into

You can find the trailhead to your old accounts by looking at the following:

• The Department of Labor runs a Retirement Savings Lost and Found database, created by the SECURE 2.0 Act of 2022, that matches your Social Security number against plan data submitted by employers. It covers workplace plans, both pensions and defined-contribution plans like 401(k)s. It does not cover Individual Retirement Accounts, and it does not cover plans sponsored by governmental entities or certain religious organizations. That last exclusion matters for physicians, since some hospital systems are public or church-affiliated employers.
• Old W-2 forms. The Box 12 codes show elective deferrals by year, which tells you a plan existed even when you can't remember the vendor.
• The former employer's benefits department. Even after a merger or an acquisition, someone still owns the plan records.
• Form 5500 filings. Employer plans covered by the Employee Retirement Income Security Act file an annual report, and those filings are searchable on the Department of Labor's site. The filing names the plan administrator and the service providers, which is often enough to find the current recordkeeper.
• Your state's unclaimed property office, plus the state where you trained. Forced-out balances sometimes land there.

For each account you find, write down five things: the plan name, the recordkeeper, the balance, whether the money is pre-tax or Roth, and whether there's an outstanding loan against it. That last one is easy to miss but very important, because an unpaid plan loan can be treated as a taxable distribution once you separate from the employer.

The Four Places an Old Account Can Go

Every orphaned workplace account has the same four destinations. The table below compares them on the details that tend to drive the decision in a physician household, including the backdoor Roth effect that general rollover advice leaves out.

Three of those four keep the money inside the retirement system, so the decision can be revisited later. The fourth is the hardest to walk back, and after sixty days it generally can't be. Cashing out converts retirement money into ordinary income sitting on top of a physician salary, at your top marginal rate, in a single year. There's a separation-from-service exception to the 10% additional tax for workplace plans if you leave the employer in or after the year you turn 55, and other exceptions exist, but the ordinary income tax is still due either way.

The Backdoor Roth Catch Behind the Individual Retirement Account Option

Here's the piece that reorders the usual ranking. If your income is above the direct Roth contribution limit, which it likely is as an attending, you may be doing a backdoor Roth each year: a nondeductible contribution to a traditional Individual Retirement Account followed by a conversion to a Roth Individual Retirement Account. Done cleanly, that conversion is tax-free if performed properly, because the dollars being converted were already taxed.

The pro-rata rule is what makes the word "cleanly" load-bearing. When you convert, the Internal Revenue Service doesn't let you choose which dollars you're converting. It looks at the combined balance of all your traditional, Simplified Employee Pension (SEP), and SIMPLE Individual Retirement Accounts as of December 31 of that year, adds the amount you converted, and works out what share of the total is after-tax basis. That share is the portion of your conversion that escapes tax. The rest is taxable. The whole calculation runs on Internal Revenue Service Form 8606, Nondeductible IRAs, which is also where your after-tax basis is tracked from one year to the next.

Roll a pre-tax 401(k) into a traditional Individual Retirement Account in March, and that balance is sitting in the pool on December 31. The conversion you expected to be a non-taxable event may become largely taxable instead. The tax isn't lost forever, since you pick up basis you'll recover eventually, but you've moved taxable income into a year when your marginal rate is already high.

Money inside an employer plan isn't in that pool. Neither is a Roth Individual Retirement Account, and neither is an inherited one. That single fact is why the second option in the table, rolling into your current employer's plan, matters so much if you run a backdoor Roth every year, and why the Individual Retirement Account route, the default suggestion almost everywhere else, may carry a cost specific to your tax situation.

If you moonlight or take locums work, there's a related trap. A SEP-IRA counts in the pro-rata pool the same way a traditional Individual Retirement Account does, which is one of the trade-offs that surfaces when you compare a solo 401(k) against a SEP-IRA for 1099 side income. A solo 401(k) is a plan, so its balance stays out of the pool.

Direct Transfer Versus the Sixty-Day Rollover

There are two mechanical ways to move money between retirement accounts, and they aren't equally forgiving.

In a direct rollover, sometimes called a trustee-to-trustee transfer, the old plan sends the money straight to the new plan or custodian. If a paper check is involved, it's made payable to the receiving institution for your benefit, not to you personally. Nothing is withheld and nothing is reportable as income.

In a sixty-day rollover, the plan pays you and you have sixty days to redeposit the money. The Internal Revenue Service is direct about what happens in between: a plan distribution paid to you is subject to mandatory 20% withholding even when you fully intend to roll it over. To complete the rollover without tax, you have to replace that withheld 20% out of other money and wait to recover it when you file. Miss the sixty days and the entire amount may be treated as a taxable distribution, potentially with the 10% additional tax on top, unless you qualify for a waiver of the deadline.

One more wrinkle is worth knowing. The one-rollover-per-twelve-month limit applies to rollovers between Individual Retirement Accounts. It doesn't apply to trustee-to-trustee transfers, and it doesn't apply to rollovers coming out of an employer plan. A direct transfer sidesteps the withholding, the deadline, and that annual limit at the same time, which is why it's the simpler route in nearly every case.

Reading the Fee and Fund Menu Before Anything Moves

Comparing plans on cost takes longer than comparing them on convenience, and it's the step most often skipped.

The Department of Labor's booklet A Look at 401(k) Plan Fees walks through the three categories that show up in a workplace plan: plan administration fees, investment fees, and individual service fees. Its own illustration shows how a one percentage point difference in annual fees can compound into a meaningfully smaller balance over a working career. You don't need to run that math yourself. You do need to know what each of your plans charges.

A few things are worth reading off each statement: whether the recordkeeping fee is a flat dollar amount per participant or a percentage of your balance, what the fund-level expense ratios look like, and whether the plan bills separately for loans or distributions. Large hospital systems sometimes negotiate institutional pricing a retail Individual Retirement Account can't match. Small practice plans sometimes carry layered fees an Individual Retirement Account easily beats. Either is possible, and you can't guess which one you have.

The fund menu matters too, and so do features that never appear on a fee schedule. Some plans allow after-tax contributions with in-plan Roth conversions, the feature behind what's commonly called a mega backdoor Roth. Some hold a stable value option, a principal-preservation account you can't replicate outside a plan. And some accept incoming rollovers while others don't. Two questions decide which of the four options are actually on your table: does your current plan accept rollovers from a prior employer's plan, and does it accept pre-tax Individual Retirement Account money?

The Governmental 457(b) Follows Its Own Rules

If one of your old jobs was at a public hospital or a state university system, you may have a 457(b) in the pile, and it doesn't behave like the others. The distinction that matters is whether the plan is governmental or non-governmental. The two are treated very differently.

A governmental 457(b) holds assets in trust for you. The Internal Revenue Service's guidance on pension and annuity withholding confirms that a distribution from a governmental 457(b) is an eligible rollover distribution just like a 401(k) distribution, subject to mandatory 20% withholding unless it's paid as a direct rollover to an Individual Retirement Account or another eligible retirement plan. Whether the receiving plan will take it is a separate question, since accepting rollovers is an optional feature that has to be written into the plan document.

There's a trade-off buried in that. Money in a governmental 457(b) is generally reachable after you separate from that employer without the 10% additional tax that applies to early 401(k) or Individual Retirement Account withdrawals. Roll those dollars into a 401(k) or an Individual Retirement Account and they may take on the receiving account's rules, including that additional tax, until you reach 59 and a half. If you're thinking about stepping back at 52, the rollover changes when you can reach that money.

A non-governmental 457(b), the kind a nonprofit hospital offers, is a different instrument altogether. As the Internal Revenue Service's guidance on non-governmental 457(b) deferred compensation plans explains, these plans must remain unfunded: the money stays an asset of the employer, available to that employer's general creditors, until it's paid out to you. It generally can't be rolled into an Individual Retirement Account or a 401(k) at all. At most it may be transferred to another non-governmental 457(b), and only if both plans permit it. Our view is that the forfeiture risk deserves real caution, whether you're deciding what to do with an old balance or whether to contribute at all.

Four Accounts, Four Different Questions

Say you're eight years out of residency, married, two kids, filing jointly, and you do a backdoor Roth every January. Your accounts look like this.

• A residency 403(b) with a modest pre-tax balance at a recordkeeper you haven't logged into since 2018.
• A 401(k) from your first attending job with a larger pre-tax balance and a fund menu you remember being thin.
• A governmental 457(b) from that same employer, which was a county hospital.
• Your current employer's 403(b), which you fund to the limit every year.

Four accounts, four separate conversations. The residency 403(b) raises a question about whether the balance is still there or was forced out years ago. The old 401(k) raises the pro-rata question head-on: rolling it into an Individual Retirement Account would put a pre-tax balance in the December 31 pool your January conversion runs through, while rolling it into your current 403(b) would not. The governmental 457(b) raises the early-access trade-off, which turns on whether you're thinking about reducing clinical hours in your early fifties. Your current plan raises the fee question: is it the cheapest place for the rest of the money, or the most expensive?

None of those questions has a universal answer, and they interact. What happens with the 401(k) depends on what your current plan accepts. What happens with the 457(b) depends on a career timeline you may not have settled yet. This is the kind of decision where sitting down with your specific numbers alongside a CFP® professional, and your tax preparer where taxes are involved, tends to produce a different answer than a general article can.

Pulling the Scattered Accounts Into One Plan

Consolidating isn't worth doing just because fewer accounts is tidier. It's worth doing because a plan you can see is a plan you can adjust. When the money sits in one or two places, your mix of stocks and bonds is something you chose rather than something you inherited, rebalancing is a single afternoon instead of four, and your beneficiary information lives in one place instead of on forms you filled out during intern year.

Timing tends to cluster around a job change, when the old plan is fresh in your mind and the new plan's paperwork is already open on your desk. If you're in that window right now, the financial moves that come with a new attending position covers the other decisions landing at the same time, several of which interact with this one.

Pull the last statement from every plan you've left behind, the residency 403(b), the fellowship account, the first attending job, and write five lines for each: plan name, recordkeeper, balance, pre-tax or Roth, and any outstanding loan.
