What happens to your 403(b) when you quit: don’t assume it follows you

How long until the hospital match is yours?

A year before her last shift, Bev needed to find out whether the hospital money in her 403(b) was actually hers. Your own 403(b) deferrals and their earnings are 100% vested from day 1, but an employer match can have a vesting schedule that makes you wait before you own all of it.

In an ERISA-covered hospital 403(b), employer money may use a 3-year cliff or a graded schedule that reaches 100% by year 6. A year of service often means 1,000 hours, not 12 calendar months. Bev worked 3 twelve-hour shifts a week, or 36 hours. Over 48 working weeks, 36 × 48 equals 1,728 hours, well over 1,000. Per-diem work or a reduced-FTE year can tell a different story.

If a job change is close, get three answers from HR on paper: the date your vesting clock started, the unvested dollars in the account today, and whether leaving ends your hospital’s 403(b)-only 15-year catch-up. That catch-up does not carry to the next employer, so settle the IRS-limit question before you pick a last day. If HR says “We can only tell you after termination is processed,” push back before you resign.

Midflorida Credit Union asks for the vesting schedule before discussing a rollover. Governmental and church-run hospital plans are often outside ERISA, so their vesting, forced-rollover, and beneficiary rules may differ. Read the summary plan description for your own account.

The 1,000-hour test

What age makes an early draw penalty-free?

Money taken from a 403(b) before 59½ usually faces a 10% additional tax, but leaving the hospital in the calendar year you turn 55 or later can remove that charge for money left in that hospital’s plan. The age-55 rule does not follow funds into an IRA. For a nurse 10–15 years from retirement, it mainly matters during an unpaid gap between jobs or an earlier-than-planned stop.

Bev’s last 4 months at her hospital

Bev, 58, gave notice in March after working ICU charge for years and planned to move hospitals (hypothetical, round numbers). She is divorced, works 3 twelve-hour shifts each week, has 2 adult kids, and has about $620K spread across 4 accounts from 3 hospitals. Her current hospital 403(b) holds $90K, including $12K of employer match on a 3-year cliff that she reaches in July.

Leaving in March would forfeit the $12K. Staying 4 more months keeps it. That is money she had already earned through her work, even though the account had not vested yet.

At 58, Bev also has an age-55 option. Because she left after the calendar year she turned 55, she can use money that stays in this hospital’s 403(b) without the 10% additional tax if the next job does not work out. If she rolls the $90K to an IRA, that exception disappears until she reaches 59½, about 18 months later.

The future value gives the delay some context. Assuming 5% annually for illustration, 1.05 raised to the ninth power is about 1.55. $12K × 1.55 equals about $18.6K at age 67. You can test your own match with the growth calculator on this site. Treat that $18.6K as an illustration, not a forecast; markets can fall, and the balance could drop below the amount Bev contributed.

Bev set her last shift for the week after the July vesting date. She left the $90K where it was until 59½, kept the other accounts out of this decision, and expected to combine accounts later. Midflorida Credit Union wrote down the July vesting date, her 59½ date, and the account she intended to keep on her one-page roadmap, so she could explain the choice to her adult kids in a minute.

Why the age-55 rule stays with the hospital account

The separation letter and small balances

Two to 6 weeks after Bev’s final paycheck, the old hospital could send a separation letter. A plan may mail a check for a vested balance below $1K without consent. It may place $1K to $7K into an IRA chosen by the plan if you do not choose a destination. More than $7K generally remains in the old account until you act.

Watch the middle row: a $5K balance can leave the hospital account even when you never open the mail. The SECURE 2.0 law allowed plans to raise the forced-out cutoff from $5K to $7K. A nurse who left $6K behind under the old assumption may discover a new IRA at a provider she never selected.

The $7K forced-out threshold

The 30-day reply window

The old plan must give you a rollover notice at least 30 days before paying out, unless you waive the wait. If you do not reply, the default listed in that letter can take effect. Update your mailing address and email before your last shift; a notice arriving during a run of night shifts is easy to miss.

How much of a cash-out reaches your bank?

A cash-out becomes ordinary income for the year it is paid, on top of wages and overtime. The 20% federal withholding is a deposit toward your eventual tax bill, not the final amount. Under 59½, the 10% additional tax generally also applies unless the age-55 rule covers that particular hospital account.

The IRS requires Form 1099-R by January 31 for the distribution. A 60-day rollover can sometimes repair a cash-out, but you must replace the 20% withheld from your own savings. On a $5K check, that means finding $1K to roll over even though it went to federal withholding.

A new hospital’s payroll can keep taking 403(b) contributions without knowing what the old plan already took. Say you defer $20K from January through June, then $15K from July through December. That is $35K, or $2,500 above the IRS 2026 age-50-plus total of $32,500 ($24,500 plus $8,000). If the excess is not removed by April 15 of the next year, the $2,500 is taxed now and again when later paid out. Give new payroll the final old paystub showing your year-to-date deferral amount.

The IRS also requires Roth catch-up contributions when your prior-year FICA wages from that employer exceeded $150,000. A high-overtime nurse starting at a new hospital may have no prior-year wages there, so payroll should confirm the treatment. Bev reaches age 60 in 2 years. The 2026 catch-up limit for ages 60–63 is $11,250, so she should check the current limit for the year she turns 60.

What happens to an old 403(b) once you quit: 3 options compared

The year after Bev left, she had 3 practical choices: leave the old 403(b), move it into the new hospital’s 403(b), or roll it to an IRA. Leaving it preserves the age-55 exception. The new plan can reduce account count, while an IRA usually offers more fund choices. The right answer rests on fund cost, access, and whether the new plan accepts incoming money.

The comparison shows why a rollover should not be automatic. Before Midflorida Credit Union suggests moving an old account, it lists every account held and the annual fund cost of each option. A move makes sense only when it leaves fewer accounts at a lower cost. The full rollover process is covered in Questions for a financial advisor before moving your 403(b).

Beneficiary forms do not travel with the money. Bev never rolled the $90K, so she filed a new form on each of her 4 old accounts and replaced her former husband with her 2 adult kids. In an ERISA plan, a named beneficiary can still receive the account after divorce. A married nurse who names someone other than a spouse in an ERISA plan needs the spouse’s written consent. Non-spouse heirs generally must empty inherited accounts within 10 years, so adult children need a list of old accounts and current beneficiary forms.
