Changing jobs triggers a decision most people aren't prepared for: what to do with the 401(k) at the old employer. The account doesn't disappear when you leave, but you have a limited window to move it on your terms. Getting this right avoids an unnecessary tax bill; getting it wrong can cost you 30% or more of the balance in a single year.
Your four options when you leave a job
Per the IRS rollovers guidance, you have four choices for an employer-sponsored retirement plan when you separate:
Leave it with the old employer. Allowed as long as your balance exceeds the plan's forced-rollover threshold (usually $5,000). The money stays invested in the plan's available funds. You lose access to the old employer's HR portal and may face limited investment options; required minimum distributions still apply at age 73.
Roll it to your new employer's plan. If your new employer's plan accepts incoming rollovers (not all do), this consolidates your retirement savings and keeps you under one roof. Check with the new plan administrator before assuming it's an option.
Roll it to an IRA. The most flexible path for most people. An IRA opens the full universe of investment options — individual stocks, bonds, ETFs, mutual funds — rather than the curated menu inside a company plan. You can open an IRA at any major custodian (Fidelity, Vanguard, Schwab) at no cost.
Cash it out. The costliest option. The distribution is included in your gross income for the year and taxed as ordinary income. If you are under age 59½, the IRS adds a 10% early withdrawal penalty. On a $50,000 balance, cashing out at a 22% marginal tax rate plus the 10% penalty costs roughly $16,000 in combined taxes — before any state income tax.
For most people, option 3 — rolling to an IRA — provides the most flexibility and preserves the full value of the account.
Direct vs indirect rollover: the mechanics matter
Once you decide to move the 401(k) to an IRA, you have two ways to execute the transfer.
Direct rollover — the plan sends the funds directly to your new IRA provider, either by electronic transfer or a check made payable to the IRA custodian (not to you). No federal withholding. No 60-day clock. The IRS does not treat a direct rollover as a distribution. This is the standard and recommended method per IRS Publication 590-A.
Indirect rollover — the plan issues a check payable to you. The plan is legally required to withhold 20% of the taxable amount for federal income tax. If the account held $80,000, the check arrives for $64,000. You now have 60 calendar days to deposit the full $80,000 — including the $16,000 that was withheld — into the IRA. If you deposit only the $64,000 check, the withheld $16,000 is treated as a distribution: taxable income plus the 10% penalty if you're under 59½. You can recover the withheld 20% when you file your taxes (since the withholding is prepaid federal tax), but only after you've absorbed the tax and penalty on the shortfall.
The practical guidance: always request a direct rollover. There is no tax or financial benefit to taking the indirect path.
Pre-tax 401(k) money: traditional IRA or Roth IRA?
Most 401(k) contributions are pre-tax — your contributions reduced your taxable income in the year they were made, and the earnings have grown tax-deferred. When you roll that pre-tax money into an IRA, you choose:
→ Traditional IRA: The direct rollover is tax-free. The balance continues to grow tax-deferred, and you pay ordinary income tax only when you withdraw in retirement. This is the straightforward, default path that preserves the tax-deferred status you already have.
→ Roth IRA: This is a Roth conversion. The converted amount is included in your gross income for the year — taxed at your current marginal rate. After the conversion, the balance grows tax-free and qualified withdrawals in retirement are completely tax-free. There is no income limit on Roth conversions and no early withdrawal penalty on the conversion itself.
The decision comes down to the same tax-timing question as any Roth vs. traditional comparison: is your marginal rate higher today or in retirement? See Roth IRA vs. Traditional IRA: How to Choose in 2026 for the full framework. If your income is high enough that you're above the direct Roth IRA contribution phase-out, a 401(k)-to-Roth-IRA conversion at job change is a clean window to build tax-free retirement assets — see the backdoor Roth IRA guide for how this interacts with the pro-rata rule if you already have pre-tax IRA balances.
Roth 401(k) balances: roll to a Roth IRA tax-free
If your 401(k) included a designated Roth contribution account — an after-tax deferral tracked separately from the pre-tax balance — that portion rolls directly into a Roth IRA with no tax due. Both accounts hold after-tax dollars, so no conversion event occurs.
One nuance: the Roth IRA five-year holding period for tax-free earnings withdrawals begins when the Roth IRA was first opened, not when the rollover happened. If you already have a Roth IRA open, the rollover inherits the existing five-year clock. Your contribution basis (the original after-tax amounts) is always available for withdrawal at any time without tax or penalty regardless of age or holding period.
The one-rollover-per-year rule
The IRS one-rollover-per-year rule restricts how often you can use an indirect rollover to move money between IRAs. You cannot use the 60-day indirect rollover method more than once across all your IRAs within any 12-month period. A second indirect IRA-to-IRA rollover within 12 months is treated as a taxable distribution.
What this rule does not restrict:
- Rolling a 401(k) into an IRA — employer plan rollovers are specifically excluded
- Direct trustee-to-trustee transfers between IRAs
- Roth conversions from a traditional IRA to a Roth IRA
- Any number of direct rollovers from 401(k) plans
The practical effect: if you move jobs twice in one year and do direct rollovers both times, there is no issue. The rule only catches the indirect (check-to-you) path.
Self-employed owners: different account options apply
If you leave an employer and plan to work for yourself, you're no longer limited to rolling into a traditional or Roth IRA. You can establish a Solo 401(k) or SEP-IRA for your new self-employment income and roll the old 401(k) into that plan. Both accept incoming rollovers from prior employer plans and allow much higher annual contributions than a standard IRA — up to $72,000 combined for 2026, compared to $7,500 for an IRA.
