Yes, you can transfer a 401(k) to another company’s 401(k) plan once you’ve left the employer that sponsors the old plan, as long as the new employer’s plan accepts incoming rollovers. The safest route is a direct rollover, where the funds move trustee-to-trustee and never pass through your hands. That one choice is what keeps the IRS out of the transaction and avoids the automatic 20% federal withholding that applies when a distribution check is cut to you personally.1Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
When You Can Move the Money
Leaving the job is the usual trigger. Once you separate from service, you have full control over your vested balance and can send it to a new employer’s plan or to an IRA. While you’re still employed, federal rules generally block you from pulling your elective deferrals out until you turn 59½, become disabled, or qualify for a hardship distribution.2Internal Revenue Service. 401(k) Resource Guide – Plan Participants – General Distribution Rules
The receiving plan matters just as much. Every qualified plan has to let participants roll money out, but no plan is required to accept rollovers coming in.3eCFR. 26 CFR 1.401(a)(31)-1 – Requirement to Offer Direct Rollover of Eligible Rollover Distributions Check the Summary Plan Description for the new 401(k) or ask the plan administrator directly. Most large employer plans accept rollovers, and many will take your money in before you’re even eligible to begin making your own contributions.
Only Your Vested Balance Transfers
Every dollar you contributed from your own paycheck is yours. The employer match is governed by a vesting schedule, and whatever hasn’t vested on the day you leave gets forfeited back to the plan.4Internal Revenue Service. Retirement Topics – Vesting
Two structures are common:
- Cliff vesting. You own 0% of the match until you reach a milestone (often three years of service), then jump to 100%.
- Graded vesting. Your ownership grows each year. A typical six-year schedule gives you 20% after year two, 40% after year three, and so on, reaching 100% at year six.
If you’re close to a vesting milestone, do the math before giving notice. A few extra months on the payroll can mean keeping thousands more in the account you’re about to roll over.
How to Complete a Direct Rollover
Start by gathering what you’ll need from the receiving side: the new plan’s full name, its trustee or custodian, the Employer Identification Number (EIN), and the mailing address for incoming rollovers. From the old plan, pull your account number, your most recent statement, and a note of any outstanding loan balance.
Then contact the old plan’s administrator (or log into the participant portal) and request a distribution form. Select the direct rollover option. That selection is the single most consequential box on the paperwork, because it tells the plan to make the check payable to the new trustee “for the benefit of” (FBO) you, rather than to you personally. A check written FBO your name keeps the funds tax-deferred and sidesteps the 20% mandatory withholding that applies the moment a distribution is payable to you.1Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
If your old balance holds both traditional (pre-tax) and Roth money, identify each piece on the form. Roth 401(k) dollars have to land in a Roth account at the new plan or in a Roth IRA to preserve their tax-free growth. Letting them mix with pre-tax money creates a problem that’s painful to unwind.
Signatures and Spousal Consent
Most administrators require your signature on the distribution request, and some ask for a Medallion Signature Guarantee when the check is going somewhere other than the address on file. That’s a plan-level policy, so ask before mailing anything.
Spousal consent in writing is required if your plan is subject to joint-and-survivor annuity rules, such as a money purchase pension plan. It isn’t required when the lump-sum value of the benefit is $5,000 or less.5Internal Revenue Service. Fixing Common Plan Mistakes – Failure to Obtain Spousal Consent Standard 401(k) profit-sharing plans usually don’t require spousal consent for a distribution, though they do for naming someone other than your spouse as beneficiary.
Submitting and Confirming
Submit through the old plan’s secure portal if available; digital requests process faster than mailed paperwork. The old administrator typically takes about five to ten business days to verify and issue the distribution. Distribution fees in the $25 to $100 range are common.6U.S. Department of Labor. A Look at 401(k) Plan Fees
Even on a direct rollover, the check sometimes arrives at your home instead of the new plan’s processing address. Don’t cash it. Forward it unopened (or per the new plan’s instructions) to the receiving department. Your account is almost always liquidated to cash before the transfer, so once the money lands you’ll need to pick new investments in the new plan.
Why You Don’t Want the Check Made Out to You
If the old plan cuts a distribution check payable to you, two things happen immediately. The plan withholds 20% for federal taxes, and you have 60 days from the date you receive the money to deposit it into another qualified plan or IRA. Miss the window and the entire amount becomes taxable income for the year, plus a 10% early withdrawal penalty if you’re under 59½.7Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust
The withholding is the real trap. On a $50,000 balance you’d receive $40,000. To complete a full rollover you’d have to come up with $10,000 from your own pocket and deposit the full $50,000 into the new plan within 60 days. You’d get the $10,000 back as a refund at tax time, but many people can’t front it. Direct rollover avoids the entire problem.
Missing the 60-Day Deadline
The IRS can waive the deadline when you missed it for reasons outside your control, like a serious illness, a natural disaster, or an error by the financial institution.8Internal Revenue Service. Retirement Plans FAQs Relating to Waivers of the 60-Day Rollover Requirement Under Revenue Procedure 2020-46 you can self-certify your eligibility by giving the receiving plan or IRA a written statement, and the institution can accept the late deposit as long as it has no reason to doubt the certification.9Internal Revenue Service. Accepting Late Rollover Contributions An automatic waiver also applies when the institution received your money on time but failed to deposit it due to its own error, provided the deposit happens within one year.
If You Have an Outstanding 401(k) Loan
An unpaid 401(k) loan is the most overlooked complication in a plan transfer. Leave the employer with a loan you can’t repay, and the plan treats the unpaid balance as a distribution, reporting it to the IRS on Form 1099-R.10Internal Revenue Service. Retirement Topics – Plan Loans That means income tax on the balance, and potentially the 10% early withdrawal penalty on top.
The qualified plan loan offset (QPLO) rule softens the blow. When your account is reduced to pay off a defaulted loan at separation, you get until your tax filing deadline for that year (including extensions) to roll the loan amount into an IRA or another eligible plan. So if your balance was $80,000 with a $15,000 loan, the plan might direct-roll $65,000 and treat the $15,000 as a plan loan offset. You then have until your tax deadline to come up with $15,000 from elsewhere and deposit it into an IRA to avoid tax on that piece. No 20% withholding applies to the offset portion itself when the rest of the balance moves as a direct rollover.11Internal Revenue Service. Plan Loan Offsets
What Happens If You Do Nothing
Ignoring an old 401(k) doesn’t mean it waits for you indefinitely. The old plan’s options depend on the balance:
- $1,000 or less. The administrator can cash you out, with 20% withheld for taxes, without asking.1Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
- $1,001 to $7,000. The plan can automatically roll the balance into an IRA in your name if you don’t give instructions. The SECURE 2.0 Act raised this threshold from $5,000 to $7,000 starting in 2024.
- Over $7,000. The plan has to get your consent before moving anything.
Those automatic rollover IRAs tend to sit in low-yield money market funds with maintenance fees that quietly erode the balance. If you’ve lost track of an old 401(k), it may already be in one. Tracking it down and consolidating is almost always worth the effort.
New 401(k) vs. an IRA
Rolling into the new employer’s plan isn’t the only option. A traditional IRA (or, for Roth 401(k) money, a Roth IRA) is also eligible. The trade-offs matter.
The Rule of 55
If you separate from service during or after the year you turn 55, you can take penalty-free withdrawals from that employer’s 401(k). The exception does not apply to IRAs.12Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions Roll the money into an IRA and you lose this exception for those funds. Anyone planning to retire between 55 and 59½ should weigh that carefully.
Creditor Protection
Assets in ERISA-qualified 401(k) plans get strong federal protection from creditors, in and out of bankruptcy. IRAs get less. Outside of bankruptcy, IRA protection varies by state. If lawsuit exposure is a concern, a 401(k) is the sturdier shield.
After-Tax Contributions
If the old plan holds after-tax (non-Roth) contributions, a rollover lets you split them cleanly: pre-tax dollars to a traditional IRA or new 401(k), after-tax dollars to a Roth IRA, as long as the distributions happen at the same time.13Internal Revenue Service. Rollovers of After-Tax Contributions in Retirement Plans It’s one of the few situations where routing through an IRA is clearly better, because it converts after-tax dollars to Roth dollars with no additional tax.
Blackouts During Plan Transitions
If your company is merging plans or switching providers, you may run into a blackout period of more than three consecutive business days during which you can’t direct investments or request distributions. Federal rules require at least 30 days’ advance notice before a blackout begins.14eCFR. 29 CFR 2520.101-3 – Notice of Blackout Periods Under Individual Account Plans The 30-day notice is waived for blackouts tied to a merger or acquisition; in those cases the administrator must give notice “as soon as reasonably possible.” If a transition is coming, start the rollover early.
Report the Rollover on Your Taxes
Even a direct rollover that owes no tax generates a Form 1099-R from the old plan. For a direct rollover to another qualified plan or traditional IRA, Box 1 shows the full distribution, Box 2a shows $0 taxable, and Box 7 carries distribution code G.15Internal Revenue Service. Instructions for Forms 1099-R and 5498 You still have to report the rollover on your federal return for the year the distribution happened. The IRS matches 1099-Rs against returns, and leaving a tax-free rollover off your return can trigger an automated notice that assumes you owe tax on the entire amount. Keep the 1099-R with your records of the deposit into the receiving account.
