When you change jobs, your old 401(k) doesn't have to stay put — but it shouldn't be cashed out on autopilot either. You generally have four options: leave it, roll it to your new plan, roll it to an IRA, or cash it out. Three of the four keep your money tax-advantaged; the fourth usually costs you taxes, a penalty, and years of compounding.
What each does
The four options, plainly
- Leave it in the old plan. Simple, keeps the money invested and tax-advantaged, but you manage another account with a former employer's limited menu.
- Roll to your new employer's plan. Consolidates, keeps plan protections and possible loan access, if the new plan accepts rollovers.
- Roll to an IRA. Broadest investment choice and consolidation; weigh fees and the creditor-protection and RMD trade-offs.
- Cash out. Fast, but before 59½ it usually means income tax plus a 10% penalty and a permanent hole in your retirement — the option to avoid unless truly necessary.
Where people get hurt
The tax traps to avoid
Use a direct, trustee-to-trustee rollover whenever possible so the funds never pass through your hands. An indirect rollover triggers 20% withholding and a 60-day clock to redeposit the full amount — miss it and the shortfall is taxed and possibly penalized. And if any of your balance is Roth or after-tax, keep those dollars tracked separately so the rollover preserves their treatment.
Be selective
Where an annuity does — and doesn't — fit
Rolled-over funds can be used to purchase an annuity for guaranteed income, and for some retirees that's a reasonable piece of the plan. But rolling a tax-deferred 401(k) into a tax-deferred annuity purely for the “tax deferral” gains you nothing on that front — the account is already tax-deferred. An annuity should be chosen for a specific job (guaranteed income, principal protection), not sold as a default rollover destination.
When this is the wrong tool — and what can go wrong
A rollover decision goes wrong when:
- You cash out a modest balance “to get by,” and lose a chunk to taxes and the 10% penalty plus decades of growth.
- You take an indirect rollover and miss the 60-day window, converting a routine move into a taxable event.
- You roll into a higher-cost IRA or product without comparing fees to your existing plan.
- You roll a tax-deferred 401(k) into a tax-deferred annuity chasing a tax benefit you already had.
- You move the money before checking creditor protection, plan-loan access, or employer-stock (NUA) considerations that applied to your situation.
