Key takeaways
- You have four options for an old 401(k): leave it, roll it into an IRA, roll it into your new employer's 401(k), or cash it out.
- A direct rollover (money moves trustee-to-trustee) avoids all tax withholding; an indirect rollover triggers a mandatory 20% withholding and a 60-day deadline.
- Cashing out is almost always the worst choice — you owe income tax plus, if under 59½, a 10% early-withdrawal penalty, and you lose decades of tax-deferred growth.
- An IRA gives you the widest investment menu; a new 401(k) keeps things consolidated, may allow loans, and preserves a clean path for a backdoor Roth.
- Match Roth-to-Roth and pre-tax-to-pre-tax to avoid an accidental taxable conversion.
Your four options at a glance
When you leave an employer, the money in your 401(k) is yours — at least the part that's vested. What happens next is up to you. Every path leads to one of four destinations, and the right one depends on your investment preferences, whether you might do a backdoor Roth, and how much you value simplicity.
| Option | Tax hit now? | Best for |
|---|---|---|
| Leave it in the old plan | None | Great, low-cost plan; balance above the force-out limit |
| Roll into an IRA | None (direct) | Wide investment choice, consolidation, low fees |
| Roll into a new 401(k) | None (direct) | Simplicity, loan access, keeping a clean backdoor-Roth path |
| Cash out | Income tax + 10% penalty if under 59½ | Almost no one — true emergencies only |
Option 1 — Leave it where it is
If your old employer's plan is good — low-cost index funds, maybe access to a stable-value fund or an institutional share class you can't get elsewhere — there's often nothing wrong with leaving the money put. Your investments keep growing tax-deferred and nothing is taxed.
Two catches. First, small balances can be forced out: plans can automatically cash out or roll over balances below a threshold (commonly $7,000) after you leave, so a small account may not be able to stay. Second, it's easy to forget an old account across several job changes, leaving your portfolio scattered and hard to rebalance. If you're the type to lose track, consolidation is worth something.
Option 2 — Roll it into an IRA
Rolling your old 401(k) into a traditional IRA is the most popular choice, and for good reason: an IRA at a major brokerage gives you a nearly unlimited investment menu and often lower fees than a workplace plan. You keep full control, and you can consolidate several old 401(k)s into one place.
Match the tax character: roll pre-tax 401(k) money into a traditional IRA, and Roth 401(k) money into a Roth IRA. A useful side benefit of moving Roth 401(k) money to a Roth IRA is that Roth IRAs have no required minimum distributions during your lifetime, while Roth 401(k)s historically did.
Option 3 — Roll it into your new employer's 401(k)
If your new job offers a solid 401(k) that accepts incoming rollovers, moving the old balance in keeps everything under one roof. Advantages over an IRA:
- Simplicity — one account, one login, one rebalancing decision.
- Loan access — 401(k)s can allow loans; IRAs cannot.
- Backdoor Roth stays clean — 401(k) balances are invisible to the IRA pro-rata rule.
- Stronger creditor protection in some states, and the ability to delay RMDs on that money if you keep working past the RMD age at that employer.
The trade-off is a narrower investment menu and potentially higher fees than a self-directed IRA. Compare the expense ratios before deciding.
Option 4 — Cash out (usually a mistake)
Taking the money as cash is the most expensive option by far. A cash-out is treated as a taxable distribution: you owe ordinary income tax on the whole amount, and if you're under 59½ you generally owe an additional 10% early-withdrawal penalty. On top of that, the plan withholds 20% for federal taxes up front, and you permanently lose the tax-deferred compounding that money could have earned for decades.
| Line item | Amount |
|---|---|
| Gross balance | $50,000 |
| Federal income tax (22%) | −$11,000 |
| Early-withdrawal penalty (10%) | −$5,000 |
| Roughly what you keep | ≈ $34,000 |
Losing roughly a third off the top is bad enough; the bigger cost is invisible. At a 7% return, that $50,000 left invested could grow to well over $200,000 in 25 years — see it for yourself in the compound growth calculator. Cashing out should be reserved for genuine emergencies with no other option.
Direct vs indirect rollover — get this right
How you move the money matters as much as where it goes.
Direct rollover (do this)
In a direct rollover, the money goes straight from the old plan to the new account — often as a check made out to the new custodian "for benefit of" you, or by wire. You never take possession of the funds, so there's no withholding and no 60-day clock. This is the clean, safe way.
Indirect rollover (be careful)
In an indirect rollover, the plan sends the money to you. Two traps spring immediately: the plan must withhold 20% for federal taxes, and you have 60 days to deposit the full amount — including the withheld 20%, which you must cover out of pocket — into the new account. Miss the deadline or fail to replace the withheld portion, and that shortfall becomes a taxable distribution with a possible penalty. You're also limited to one indirect IRA-to-IRA rollover per 12 months. Whenever possible, avoid indirect rollovers entirely.
A simple decision path
- Is the old plan excellent and the balance large enough to stay? Leaving it is fine.
- Do you (or might you) use the backdoor Roth, or value simplicity and loan access? Lean toward the new 401(k).
- Want the widest investment choice and lowest fees, and don't need a clean backdoor path? Roll to an IRA.
- Always use a direct rollover, and never cash out unless it's a true emergency.
Whichever path you choose, it's a good moment to revisit how much you're saving overall — the 401(k) contribution calculator shows how your new plan's match and contribution rate shape your long-run balance, and our guide on 401(k) vs IRA vs Roth vs HSA covers where each future dollar should go.
Frequently asked questions
How long do I have to roll over a 401(k)?
A direct rollover has no deadline — you can move an old 401(k) whenever you like. An indirect rollover, where the check comes to you, must be redeposited within 60 days or it becomes a taxable distribution.
Will a rollover trigger taxes?
A direct rollover of pre-tax 401(k) money to a traditional IRA or new 401(k) is not taxable. Taxes only arise if you cash out, miss the 60-day window on an indirect rollover, or convert pre-tax money to Roth.
Can I roll a 401(k) into a Roth IRA?
Yes, but rolling pre-tax 401(k) money into a Roth IRA is a conversion — you'll owe income tax on the amount in that year. Roth 401(k) money rolls into a Roth IRA tax-free.
What happens to my 401(k) if I do nothing?
Usually it stays invested in the old plan. But balances under a plan's force-out limit (often $7,000) can be automatically rolled to an IRA or cashed out, so very small accounts may not be left alone.
Should I roll over if I have employer stock in my 401(k)?
Be careful. Appreciated employer stock may qualify for net unrealized appreciation treatment, which can lower your tax on the gains. Rolling everything to an IRA can forfeit it — get advice first.
