Please read first. This guide is general educational information, not tax or financial advice. It may not be complete, perfectly accurate, or fully up to date — tax rules change and the specifics depend on your plan and your situation. Always confirm the details with your own licensed tax professional or financial advisor before moving any money.
When you leave a job, your old 401(k) doesn't move automatically — you decide what happens to it. There's no deadline that forces you to act immediately, but if money ever lands in your hands (an indirect rollover or a cash-out check), a 60-day clock starts, and missing it turns a routine move into a taxable event. Here are your four options and how to weigh them.
Your four options
1. Roll it over to an IRA. Move the balance into a Traditional IRA (for pre-tax money) or a Roth IRA (for Roth money). You get the widest investment menu and usually lower fees, and you can consolidate old accounts. Trade-offs: IRAs don't allow loans, the Rule of 55 (penalty-free withdrawals after separating at 55+) only applies to 401(k)s, and rolling pre-tax money into a Traditional IRA can trigger the pro-rata rule that complicates future backdoor Roth contributions (see below).
2. Roll it over to your new employer's 401(k). If the new plan accepts rollovers, this consolidates everything in one place, keeps strong federal (ERISA) creditor protection, preserves the ability to take a loan later, and — importantly — keeps pre-tax dollars out of a Traditional IRA so your backdoor Roth stays clean. Downside: 401(k) menus are narrower than an IRA's.
3. Leave it with your old employer. You can generally keep the money in the old plan if your balance is at least $7,000. Under the SECURE 2.0 Act (effective 2024), plans can force out balances below that threshold: balances of $1,000 or less can be cashed out to you, and balances between $1,000 and $7,000 can be automatically rolled into an IRA the plan chooses. Leaving it is fine short-term, but old accounts are easy to lose track of.
4. Cash it out. You take the money as a distribution. For pre-tax balances this is ordinary income in the year you take it, plus a 10% early-withdrawal penalty if you're under 59½ (the Rule of 55 can waive the penalty if you separated in or after the year you turned 55). This is almost always the most expensive option — you lose the tax-advantaged growth and hand a large slice to taxes immediately.
The 60-day rollover window
If you do an indirect rollover — the plan sends the money to you — you have 60 days from the date you receive it to deposit it into another qualified account. Miss the deadline and the IRS treats the whole amount as a taxable distribution (plus the 10% penalty if you're under 59½). The clock runs from the date you receive the funds, not the date of your last paycheck.
A direct rollover (trustee-to-trustee, where the money goes straight from the old plan to the new account and never touches your bank account) has no 60-day clock and no withholding. When you can, always choose the direct route.
Direct vs. indirect — and the withholding trap
This is the gotcha that catches the most people:
- Direct rollover: funds move plan-to-plan or plan-to-IRA. No tax is withheld. Nothing is reportable as income.
- Indirect rollover: the check is made out to you. The plan is required to withhold 20% of any pre-tax amount for federal taxes. To roll over the full original balance within 60 days, you have to make up that withheld 20% out of your own pocket. If you only deposit the 80% you received, the missing 20% is treated as a taxable distribution — taxed and (if you're under 59½) penalized.
There's also a one-rollover-per-12-months limit on indirect IRA-to-IRA rollovers. It does not apply to direct rollovers or to 401(k)-to-IRA rollovers — another reason to keep it direct.
Roth vs. Traditional treatment
What you started with determines what's taxable:
- Pre-tax (Traditional) 401(k) → Traditional IRA: no tax. Money stays tax-deferred.
- Roth 401(k) → Roth IRA: no tax. Note the Roth IRA's own 5-year clock can affect when earnings come out tax-free.
- Pre-tax 401(k) → Roth IRA: this is a Roth conversion — fully taxable as income in the year you do it. Sometimes worth it in a low-income year (like one with a mid-year layoff), but run the numbers first.
The mega-backdoor reset
If your old plan allowed after-tax (non-Roth) contributions on top of the regular limit — the "mega-backdoor Roth" — leaving the job is your chance to finally separate that sub-account, which is often stuck in-plan while you're employed:
- After-tax contributions can be rolled into a Roth IRA tax-free.
- The earnings on those contributions are pre-tax and go to a Traditional IRA (or convert them to Roth and pay tax on just the earnings).
One caution: rolling pre-tax 401(k) money into a Traditional IRA puts a pre-tax balance in your IRA, which triggers the pro-rata rule on any future backdoor Roth IRA contributions — meaning part of each backdoor conversion becomes taxable. If you use the backdoor Roth strategy, rolling pre-tax money into your new employer's 401(k) instead of an IRA keeps it out of the pro-rata calculation.
What to ask before you move anything
- Does my new employer's 401(k) accept incoming rollovers?
- Is my balance above the $7,000 keep-it-here threshold?
- Can the plan do a direct trustee-to-trustee transfer (no check to me)?
- Do I have any after-tax contributions that should be split out to a Roth IRA?
- Do I currently use the backdoor Roth IRA? If so, would rolling pre-tax money into an IRA create a pro-rata problem?
When you open an IRA to receive a rollover, compare providers on fees and fund selection — the account is yours for decades, so the difference compounds. The IRS spells out the rules in Publication 590-A (Contributions to IRAs) and rollover treatment in Rollovers of Retirement Plan and IRA Distributions.
