Your Four Options When Changing Jobs
Job change 401k options and their consequences
| Option | Action | Taxes/Penalties | Impact on Growth | Recommended? |
|---|---|---|---|---|
| Roll to new employer plan | Transfer balance to new 401k | None | Continuous compounding | Yes, if new plan has good funds |
| Roll to IRA | Transfer to personal IRA | None | Continuous compounding, more options | Yes — often best option |
| Leave at old employer | Do nothing (>$5,000 balance) | None | Continues, but forgotten | Acceptable short-term only |
| Cash out | Withdraw the balance | 10% penalty + income taxes | All compounding lost | No — almost never |
35% of workers cash out their 401k when changing jobs. A $30,000 cash-out at 35: immediate cost = ~$10,000 in taxes and penalties. Long-term cost = $30,000 compounding to $228,000 at 7% by age 65. You receive $20,000 in hand while surrendering $228,000 in future wealth.
IRA Rollover: The Usually-Best Option
Rolling your 401k to an IRA gives you the widest fund selection, often the lowest fees, and complete control. Fidelity, Vanguard, and Schwab all accept 401k rollovers with no fees. Request a direct rollover (custodian-to-custodian) to avoid the 20% mandatory withholding on indirect rollovers.
New Employer 401k: When to Roll There Instead
Rolling to your new employer’s 401k makes sense if: (1) the new plan has lower fees or better funds than you’d get in an IRA, (2) you want to preserve 401k-specific protections (401k assets have stronger creditor protection than IRA assets in some states), or (3) you plan to use backdoor Roth IRA (pro-rata rule makes IRAs complicated).
The Rollover Process: Step by Step
- Contact your old employer’s plan administrator and request a direct rollover
- Open a rollover IRA at Fidelity, Vanguard, or Schwab if rolling to IRA
- Provide the receiving account information to the old plan
- Choose investments in the new account immediately upon receipt (don’t leave as cash)
- Confirm the transfer completed within 60 days
- Track all rollovers for tax reporting — Form 5498 confirms the rollover, Form 1099-R shows the distribution
