When you leave a job, you can move your old 401(k) into a new plan or an IRA through a rollover. Done correctly, a rollover preserves the account's tax advantages and consolidates your savings. Done carelessly, it can trigger taxes, penalties, and mandatory withholding, so the mechanics matter.
Your four options for an old 401(k)
When leaving an employer you can generally leave the money in the old plan, roll it into your new employer's plan, roll it into an IRA, or cash it out. Cashing out is almost always the worst choice because it triggers income tax and, before age 59 and a half, a 10 percent penalty. Rolling into an IRA usually offers the widest investment selection and lowest fees, while rolling into a new 401(k) can simplify RMD rules and preserve certain protections. Leaving it in place can make sense if the old plan has excellent, cheap funds.
Direct versus indirect rollovers
A direct rollover sends the money straight from your old plan to the new account, so you never take possession and no tax is withheld. An indirect rollover pays the money to you first, and you must deposit it into a new retirement account within 60 days to avoid taxes. With an indirect rollover from a 401(k), the plan is required to withhold 20 percent for taxes, which you must replace from other funds to roll over the full amount. Direct rollovers avoid this trap and are almost always the better route.
Keeping the tax treatment consistent
To avoid a tax bill, match the account types: roll pre-tax 401(k) money into a traditional IRA and Roth 401(k) money into a Roth IRA. Rolling pre-tax money into a Roth account is a conversion, which is allowed but generates taxable income in that year. Mixing them by accident can create an unexpected tax liability. Confirm with both providers how each portion of your balance will be handled before initiating the transfer.
Steps to execute cleanly
Open the destination account first, then contact your old plan administrator to request a direct rollover to that account. Ask that any check be made payable to the new custodian for your benefit rather than to you personally. Once the funds arrive, choose your investments, because rolled-over money often lands in a cash holding until you invest it. Keep records of the transaction for your tax return, since rollovers are reported even when no tax is due.
You leave a job with 50,000 dollars in a 401(k) and request an indirect rollover. The plan withholds 20 percent, so you receive 40,000 dollars but must deposit the full 50,000 dollars within 60 days to avoid tax, covering the 10,000 dollar gap yourself. A direct rollover would have moved the entire 50,000 dollars with nothing withheld.
Key takeaways
- You can leave, transfer, roll to an IRA, or cash out an old 401(k); cashing out is usually worst.
- A direct rollover avoids withholding and the 60-day deadline of an indirect one.
- Indirect 401(k) rollovers withhold 20 percent that you must replace to roll the full amount.
- Match account types so pre-tax and Roth money keep their tax treatment.
Common mistakes
- Cashing out instead of rolling over and owing tax plus a 10 percent early penalty.
- Choosing an indirect rollover and missing the 60-day window or the withheld 20 percent.
- Rolling pre-tax money into a Roth account without expecting the conversion tax.
FAQ
Is there a limit on how many 401(k) rollovers I can do?
Direct rollovers and 401(k)-to-IRA transfers are unlimited; the once-per-year rule applies only to indirect IRA-to-IRA rollovers.
Will a rollover affect my contribution limit?
No. Rollovers move existing money and do not count against your annual contribution limit for new savings.
