Changing Jobs? Your Old 401(k), the 60-Day Deadline and 20% Withholding

1. Bottom line

If you decide to move pretax savings from an old employer's 401(k) to a traditional IRA or a new employer plan that accepts rollovers, confirm the receiving account first and request a direct rollover. This generally reduces withholding and deadline risks when compared with receiving the money yourself. A properly completed rollover of eligible pretax funds to another pretax retirement account generally creates no current income tax. Moving untaxed funds to a Roth IRA generally creates taxable income for the year. IRS: Options when employment ends

This article focuses on ordinary pretax 401(k) balances owned by U.S. citizens and U.S. tax residents. Roth balances, other after-tax contributions, inherited accounts and nonresident situations require separate review.

2. Background: identify the money before choosing a transfer

After leaving a job, you may be able to keep the balance in the old plan, move it to an accepting new employer plan, roll it into an IRA or take a cash distribution. Compare fees, investment options, withdrawal rules and administration before deciding. Consolidation is only one consideration. This article explains existing rules, rather than announcing a new law.

Only eligible distributions qualify for the usual rollover treatment. Required minimum distributions (RMDs) and hardship distributions from employer plans are among the exclusions. Ask the administrator to identify the eligible amount. IRS Tax Topic 413

3. Comparing direct rollovers, 60-day rollovers and cash

Direct rollover: The old plan pays the receiving plan or IRA. A check mailed to your home can still be a direct rollover if the payee and process meet the requirements. A qualifying direct rollover avoids the 20% mandatory withholding discussed here. Follow the receiving institution's instructions instead of depositing the check in an everyday bank account.

Payment to you, followed by a rollover: For an ordinary, fully pretax, eligible 401(k) distribution paid to you, the plan generally must withhold 20% for federal income tax. You generally have 60 days after receipt to complete the rollover. To roll over the full gross amount, you need other funds to replace what was withheld.

Cash distribution without a rollover: Previously untaxed amounts generally become current taxable income. Before age 59½, a 10% additional tax may apply unless an exception is available. Withholding is a tax prepayment, not your final tax calculation.

Rollover to a Roth IRA: Pretax amounts generally create current taxable income even through a direct rollover. Review the amount alongside your other income and the cash available to pay the resulting tax.

4. Self-check before requesting a distribution

Identify pretax, Roth and other after-tax balances. Their permitted destinations and tax treatment may differ. IRS after-tax contribution guidance

Confirm that the new employer plan will accept the rollover. Plans are not required to accept incoming rollovers.

If you left that employer during or after the calendar year you turned 55 and might need money before age 59½, review the separation-from-service exception first. A qualifying distribution from that employer's plan may avoid the 10% additional tax. That particular exception does not apply to IRA withdrawals. IRS exception chart

Employer stock, an outstanding loan or an RMD due this year requires separate analysis. Do not assume the ordinary cash-rollover steps apply.

If you have already received a payment made out to you, record the receipt date and check the deadline now, rather than waiting for next year's tax preparation.

If you are a U.S. tax nonresident or preparing to leave the United States, different withholding and treaty rules may apply. Do not assume the 20% example applies. IRS Notice 2026-13

5. Example: a $50,000 balance produces a $40,000 check

Assume Ms. Lin is 40, is a U.S. tax resident and has a $50,000 old 401(k) balance entirely pretax and eligible for rollover. She has no early-distribution exception, plan loan or other special circumstance. This is a hypothetical illustration, not a client case.

Direct rollover to a traditional IRA: A properly completed $50,000 rollover generally creates no current taxable distribution and avoids the 20% withholding described here.

Payment to Ms. Lin: The plan withholds $10,000 and pays her $40,000. To complete a full $50,000 rollover within 60 days, she needs $10,000 from another source. The withholding is reconciled as federal tax paid on her return.

Rollover of only the $40,000 received: The remaining $10,000 is generally taxable. Under these assumptions, it also creates a $1,000 early-distribution additional tax, on top of ordinary income tax.

Whether the $10,000 withheld ultimately covers tax or produces a refund depends on the complete return. IRS rollover-after-withholding example

6. Action plan and timeline

Before requesting the distribution: Gather the current statement, the plan's rollover notice and the receiving institution's written instructions. Confirm the money's tax character, account details and payee. Include leaving the balance in the old plan among the options you compare.

When applying: If choosing a direct rollover, request it explicitly and confirm the process with both institutions. A button labeled “withdrawal” does not explain the tax result.

After receiving the money yourself: Check the normally applicable 60-day period against the receipt date and determine whether you must replace withholding. Relief for a missed deadline may be available in specific circumstances, but it is not automatic and should not be assumed.

After completion and at filing time: Keep outgoing and incoming confirmations and reconcile Form 1099-R. For a rollover into an IRA, retain the related Form 5498. A qualifying direct rollover generally remains reportable even when it produces no current income tax.

These are process milestones, not a universal year-end deadline. Institutions may have their own documentation and processing requirements. Sources: IRS Tax Topic 413; Forms 1099-R and 5498 instructions

7. How YCL can help

Bring the old plan statement, distribution notice, receiving-account confirmation, Form 1099-R and a summary of current-year income to discuss rollover or Roth-conversion reporting, taxable distributions and withholding, early-distribution exceptions, and federal and state reporting records.

Scope and fees depend on the agreed engagement. Your plan administrator or financial institution must confirm rollover acceptance, check instructions and transaction status. Learn about YCL's individual and family tax services.

8. Frequently asked questions

Does a check mailed to my home automatically count as a payment to me?

No. The payee and transaction process matter. A check payable to the receiving plan or IRA may still qualify as a direct rollover. Confirm the exact instructions with the receiving institution.

Does the one-rollover-per-year rule restrict an old 401(k)?

The IRA once-per-12-month rule generally concerns IRA-to-IRA rollovers in which you receive the money. It does not apply to plan-to-IRA or plan-to-plan rollovers, or direct IRA trustee-to-trustee transfers. Identify both account types and the transfer route.

Can I owe more tax even though 20% was withheld?

Yes. Final liability depends on the taxable amount not rolled over, other income, deductions and any additional tax. The withholding percentage does not settle the tax treatment.

If the direct rollover to my traditional IRA is not taxable, do I still report it?

Generally, yes. Reflect the rollover on your federal return and reconcile Form 1099-R. Sources: IRS Tax Topic 413; IRS rollover FAQs.
