Your Four Options and the Math Behind Each
403(b) options when changing jobs — tax treatment and best use case
| Option | What It Means | Tax Impact | Best For |
|---|---|---|---|
| Leave it where it is | Keep old 403(b) account open | None now | Short gap before new job, high-quality old plan |
| Roll to new employer plan | Transfer to new 403(b) or 401(k) | None if done properly | New plan has better fund options |
| Roll to IRA | Move to personal IRA at Vanguard/Fidelity | None if done properly | Best investment options, maximum flexibility |
| Cash out | Take the money | Income tax + 10% penalty if under 59½ | Never (almost) |
The Cost of Cashing Out
On a $35,000 403(b) balance, cashing out costs approximately: 10% early withdrawal penalty ($3,500) + 22% federal income tax on the full amount ($7,700) + possible state income tax ($1,000–$3,000). Total immediate loss: $12,200–$14,200. Plus the $35,000 left to grow for 25 more years at 7% would have become $190,000 — so the true long-term cost exceeds $175,000.
Only 1 in 25 job-changers who cash out their retirement account say it was the right decision in hindsight, according to Vanguard research. The immediate cash feels good; the math does not.
Rolling to an IRA: The Most Flexible Option
Rolling your 403(b) to an IRA at a low-cost provider (Vanguard, Fidelity, Schwab) gives you access to thousands of low-cost funds at 0.03–0.15% expense ratios. Compare this to your old 403(b)'s fund menu, which may have been limited and expensive. The IRA rollover is typically the best option for building long-term wealth.
How to Execute a Tax-Free Direct Rollover
- Open an IRA account at your chosen provider (Vanguard, Fidelity, or Schwab)
- Contact your old employer’s 403(b) administrator and request a direct rollover
- Provide your new IRA account number — money transfers directly, no tax withheld
- Do NOT request a check made payable to you — this triggers mandatory 20% withholding
- Once transferred, invest in your chosen fund (typically a target-date or index fund)
- Confirm the transfer completed and account shows correct balance
The 60-Day Rollover Risk
If the administrator sends you a check instead of a direct rollover, they withhold 20% for taxes. You then have 60 days to deposit the full original amount (including the withheld 20% from your own pocket) into an IRA to avoid taxes. If you miss the 60 days or cannot cover the withheld amount, that money becomes taxable income — plus a 10% penalty if you are under 59½.
When calling your old 403(b) administrator, use these exact words: 'I want a direct rollover to my IRA.' This ensures money goes institution-to-institution without passing through your hands — and avoids the mandatory 20% withholding trap.
Vesting Check Before You Leave
Before finalizing your resignation date, check your employer match vesting schedule. If you are 6 months from becoming fully vested and your unvested match balance is $4,200, delaying your start date or negotiating your last day could be worth thousands. Always get the vesting schedule from HR before deciding on a departure date.
