When you leave a job, your 401(k) doesn’t disappear — but it is at risk of being forgotten, cashed out prematurely, or left in a high-fee plan you no longer control. A 401(k) rollover moves your money to a new home where you stay in the driver’s seat.
What Is a 401(k) Rollover?
A 401(k) rollover is the process of moving funds from your old employer’s 401(k) plan to another qualifying retirement account — either an IRA or a new employer’s 401(k). Done correctly, a rollover is not a taxable event. The IRS allows you to move retirement funds between qualifying accounts without triggering income tax or penalties.
You have four options when you leave a job with a 401(k):
| Option | Pros | Cons |
|---|---|---|
| Roll over to IRA | More investment options, lower fees, full control | Loses creditor protection in some states, no Rule of 55 |
| Roll over to new 401(k) | Consolidated, loan access, Rule of 55 preserved | Limited investment options, subject to new plan rules |
| Leave in old plan | No action required | Limited control, possible high fees, may be cashed out |
| Cash out | Immediate access to cash | 10% penalty + income taxes — avoid unless emergency |
Direct Rollover vs. Indirect Rollover
Direct rollover: The plan administrator transfers funds directly to your new account. No check is issued to you. No mandatory withholding. No 60-day deadline. This is always the preferred method.
Indirect rollover: The plan issues a check payable to you. The plan is required to withhold 20% for federal taxes. You must deposit the full original amount (including the 20% withheld) into a qualifying account within 60 days. You get the withheld 20% back when you file your tax return — but only if you completed the full rollover.
Example of the indirect rollover trap: You leave a job with $100,000 in your 401(k). The plan sends you a check for $80,000 (withholding $20,000). To complete a tax-free rollover, you must deposit $100,000 into your IRA within 60 days — meaning you need to come up with $20,000 out of pocket temporarily.
How to Roll Over a 401(k) to an IRA — Step by Step
- Open an IRA at your chosen brokerage (Fidelity, Vanguard, Schwab — all free, no minimums)
- Request a direct rollover from your old plan administrator — call HR or log into your plan portal
- Specify the receiving account — provide your new IRA account number and brokerage details
- Confirm the type — rolling a traditional 401(k) to a traditional IRA is tax-free; rolling to a Roth IRA triggers income tax on the converted amount
- Track the transfer — direct rollovers typically take 5–10 business days
- Invest the funds once they arrive — rollover funds land as cash; you must reinvest them
401(k) Rollover Tax Rules
| Rollover Type | Taxable? | Withholding |
|---|---|---|
| Traditional 401(k) → Traditional IRA | No | None (direct) / 20% (indirect) |
| Traditional 401(k) → Roth IRA | Yes — full amount taxed | None (direct) / 20% (indirect) |
| Roth 401(k) → Roth IRA | No | None |
| Roth 401(k) → Traditional IRA | Not allowed | — |
How to Find an Old 401(k)
Millions of Americans have forgotten 401(k) accounts from previous employers. If you think you may have an old account:
- Contact former employer HR — they can direct you to the current plan administrator
- Check the DOL Abandoned Plan database — for accounts at terminated plans
- Search the National Registry of Unclaimed Retirement Benefits at unclaimedretirementbenefits.com
- Check your state’s unclaimed property database — plans sometimes transfer accounts to the state after years of inactivity
- Use the IRS Retirement Savings Lost and Found tool — launched in 2024 under SECURE 2.0
Can You Roll Over a 401(k) While Still Employed?
Most plans prohibit in-service distributions before age 59½. After 59½, many plans allow in-service rollovers. Some plans allow rollovers of after-tax contributions at any age — check your summary plan description.
For old 401(k)s from previous jobs, you can always roll them over regardless of your current employment status.
Rollover Mistakes to Avoid
- Taking an indirect rollover — the 20% withholding trap catches many people off guard
- Missing the 60-day deadline — the IRS allows one rollover per 12-month period per IRA; missing the deadline converts the rollover into a taxable distribution
- Rolling traditional 401(k) into Roth IRA without planning for the tax bill — the entire converted amount is taxable income in the year of conversion
- Forgetting to invest after rollover — funds arrive as cash and earn nothing until you buy investments
- Leaving small balances to be auto-cashed out — plans can distribute accounts under $1,000 without your permission
