How to handle an old 401(k) from a previous job

By Hiroshi Tanaka, CFP | Reviewed by Robert Kim, AIF | October 7, 2026

An old 401(k) from a previous job can usually stay put, move into your current hospital 403(b) or roll to an IRA, and Midflorida Credit Union compares the yearly fee gap first.

Leaving it alone feels free, but it isn’t: if $60K pays 0.8% more in fund costs than your 403(b), it gives up $480 annually and about $9,250 over 12 years, assuming 5% a year for illustration.

That $480 matters more when retirement is 10–15 years away, because every dollar spent on higher fund costs also loses its chance to compound. The right home depends on the old fund menu, your current hospital plan’s rules, your retirement date and whether a backdoor Roth could be in your future.

In reviews, Midflorida Credit Union usually sees a forgotten account with an old beneficiary form, a fee disclosure nobody has read, and another login added to an already crowded financial life. A simple roadmap can reduce that pile without forcing a move that doesn’t make sense.

Should an old 401(k) from a previous job stay where it is?

An old 401(k) can remain where it is, go into a current hospital 403(b) if that plan accepts roll-ins, move to an IRA, or be cashed out. If its total fund cost is 0.5% or more above your 403(b), or you have 3 or more retirement accounts, a direct transfer is usually worth considering.

Ask your hospital plan administrator whether roll-ins are accepted. If costs sit within 0.2% of the 403(b) and the old funds work for you, leaving it alone is reasonable. Cashing out before age 59½ is a costly fourth choice: a $40K payout loses $4K to the 10% penalty alone, before the income-tax bill. Each added account also means another statement, login and beneficiary form. After a 12-hour shift, that’s often the account nobody opens, and later it’s one more account your children must locate.

Decision rule: Move by direct transfer when the old plan costs 0.5% or more than your current 403(b), or when 3 or more retirement accounts are creating clutter. Keep it when the cost gap is within 0.2% and its funds are a good fit.

How much is the old plan costing me each year?

Start with the old plan’s annual fee disclosure, often called the Department of Labor 404(a)-5 notice. Add each fund’s expense ratio and any flat record-keeping charge, subtract the comparable 403(b) fund cost, then multiply the difference by the balance. On $60K, $60K × (1.0% − 0.2%) = $480 annually; $480 × 12 years = $5,760 before growth. Our calculator can run this math for your own balance.

The custodian often asks for the old plan’s distribution form, an acceptance letter from the receiving plan showing your account number, and directions for a check payable to the new custodian FBO you. Some requests also need a medallion signature guarantee. If the old plan has annuity choices, it may require a spouse’s notarized consent. A missing acceptance letter from the receiving 403(b) is a frequent reason these moves sit unfinished for weeks, so get that document first.

How long does a small fee gap take to add up?

A small annual gap can become more than $9K over 12 years because the dollars lost to fees no longer grow. For someone 10–15 years from retirement, the move is often about preserving catch-up years and reducing account clutter, not chasing a better-performing fund.

Abena found a $60K 401(k) from an outpatient surgery center when she was 47 (hypothetical, round numbers). Its funds charged 1.0% annually, while comparable index funds in her hospital 403(b) charged 0.2%. Assuming 5% a year before costs, for illustration, the old account grew at 4.0% and the transferred money grew at 4.8%. The first-year difference was $60K × 0.8% = $480.

By year 4, the old account reached $70,192 and the moved money reached $72,376, a $2,184 gap. By year 8, it was $82,114 versus $87,306, a $5,192 difference. At 59, 12 years later, the balances were $96,062 and $105,315. That is about $9,253 left behind by a cost gap that looked small at first.

The row at age 55 is where the choice can flip. Keeping money in the hospital 403(b) may preserve Rule of 55 access if you leave that hospital during or after the calendar year you turn 55. The IRS says the 2026 employee limit for a 403(b) is $24,500; the age-50 catch-up is $8,000, for $32,500 total. A rollover does not use any of that contribution room.

Before Midflorida Credit Union recommends a move, we line up the destination funds and calculate any tax bill. A pre-tax 401(k) sent by direct transfer to a pre-tax 403(b) produces a $0 tax bill. At 47, the fee math carries more weight. At 59, with retirement closer, access for a retirement paycheck can matter more. Money in a governmental 457(b), for example, generally avoids the 10% early-withdrawal penalty once you have left that employer. Lower fund costs improve the arithmetic, but markets can still push a balance under what you contributed.

Reggie and Abena chose a direct transfer into Abena’s hospital 403(b). Their IRA balance remained $0, and they used the added space in their household records to focus on her catch-up contributions and Reggie’s 457(b).

Is my hospital 403(b) or an IRA the better home for it?

A hospital 403(b) usually wins when you may use a backdoor Roth or could leave the hospital at 55 or later; an IRA offers more fund choices and control over timing. Compare both fund menus and fees, because a low-cost old plan or a stable value fund can be a solid reason to keep money where it is.

The 403(b) route keeps pre-tax IRA money at $0. That matters if you make a nondeductible IRA contribution and then convert it to Roth. In March, the problem often appears while a CPA completes IRS Form 8606. A $60K pre-tax IRA balance plus a $7,500 nondeductible contribution creates $67,500 total IRA money. A $7,500 conversion is about 89% taxable: $60K ÷ $67,500 = 88.9%. That makes $6,667 taxable, or roughly a $1,333 tax bill at a 20% rate, for illustration.

A mailed check creates a different trap. If the old plan pays the $60K to you, it must withhold 20%, so you receive $48K. The IRS gives you 60 days to deposit the full $60K. You would need to add $12K from savings to complete the rollover; otherwise, the missing $12K is taxable and may face a 10% penalty before 59½.

Roth and after-tax dollars need separate handling. Pre-tax IRA money can often be moved later into a workplace plan that takes incoming rollovers, but Roth IRA money cannot go into a 403(b). A cash-out cannot be repaired after the 60-day window closes, a Roth conversion cannot be recharacterized, and the IRS allows only 1 IRA-to-IRA 60-day rollover in any 12-month period. Midflorida Credit Union can place this choice beside a Roth conversion strategy and account consolidation review, so the paperwork does not create a new tax problem.

Who gets the old 401(k) if I die before I move it?

A 401(k) generally pays a spouse unless the spouse signed a written waiver, while an IRA follows the beneficiary form on file. Most adult children who inherit must empty the account within 10 years, so every extra retirement account can add another search and deadline for the family.

A form signed 15 years ago may still list a former husband, a former wife or a parent. Pull the beneficiary designation, not just the quarterly statement, and read every name and percentage. One fewer account means one fewer form your spouse or adult children may have to track down while settling an estate.

Which line of my old statement would Midflorida Credit Union read first?

Midflorida Credit Union reads the fee disclosure and beneficiary line of the old 401(k) first, then checks whether your hospital 403(b) accepts roll-ins. We put keep, move or roll on a one-page roadmap, with an estimated tax bill beside each option.

That review also separates pre-tax, Roth and after-tax balances before any form is signed. It gives you a short record your family can follow.

A $480 first-year fee gap can become about $9,253 by age 59.

Frequently asked questions about old 401(k) from a previous job

Is a direct transfer or a mailed check safer for moving an old 401(k)?
A direct transfer is usually safer because the money goes from the old plan to the receiving custodian without passing through your hands. A mailed check payable to you normally has 20% withholding. You then have 60 days to replace that withheld amount and deposit the whole balance to avoid current tax on the shortfall.
How many years before retiring should an old 401(k) be moved or closed?
Review an old 401(k) about 10–15 years before retirement, when a fee gap still has time to compound and age-50 catch-up saving begins. Review it again before leaving a hospital job at 55 or later, because moving money out of the hospital plan could give up Rule of 55 access.
My mom had a 401(k) at a clinic 20 years ago; how do we find out if it is still there?
Start with the former clinic’s human resources or benefits office and ask for the retirement-plan recordkeeper. Bring her full name used at work, Social Security number, employment dates and any old statement. If the employer no longer exists, a state unclaimed-property search and the Department of Labor’s abandoned-plan resources may help locate assets.
