How to Roll Over Your 401(k) to a Traditional IRA: Step-by-Step (2026)

Rolling a pre-tax 401(k) into a traditional IRA is the most common rollover path — and when done correctly, it's completely tax-free. But several hidden traps can turn a routine transfer into an unexpected tax bill. This guide walks you through the exact steps, the paperwork you'll receive, and the five situations where you should pause before rolling.

The short version: Request a direct rollover — your old plan transfers the money straight to your new IRA custodian. No check made out to you, no mandatory 20% withholding, no 60-day clock, no tax event.¹ The entire pre-tax balance maintains its tax-deferred status in the IRA.

Before you initiate: 5-item pre-rollover checklist

Stop here before you call your old 401(k) provider. Each of these traps is irreversible once you've rolled over.

Are you age 55–59½ and recently left this specific employer? The Rule of 55 lets you take penalty-free withdrawals from that employer's 401(k) — but only while the money stays in the plan. Rolling to an IRA permanently forfeits that exemption. If you need retirement income before 59½ and just left this job at 55 or older, model this carefully before rolling.
Do you hold highly appreciated employer stock? If your 401(k) has employer stock with a very low cost basis, the Net Unrealized Appreciation (NUA) strategy can let you pay long-term capital gains rates (0–20%) on the appreciation instead of ordinary income rates (up to 37%). Rolling that stock to an IRA permanently eliminates the NUA option — the stock converts to ordinary income when later distributed.
Do you have an outstanding 401(k) loan? If you have an unpaid loan balance and roll out, the plan will offset (deduct) the loan balance from your distribution. That offset is treated as a taxable distribution — unless you roll over an equal amount of cash elsewhere by your tax filing due date. See the loan offset rollover guide for the exact mechanics.
Does rolling pre-tax money to an IRA break your Backdoor Roth? If you make a Backdoor Roth contribution (nondeductible IRA → Roth), adding any pre-tax money to your IRA pool triggers the pro-rata rule — which taxes part of your conversion at ordinary income rates. If you do Backdoor Roth or intend to, consider rolling to a new employer's 401(k) instead, or doing a reverse rollover. Details: Backdoor Roth and the Pro-Rata Trap.
Are you age 73 or older (born 1951–1959) or age 75+ (born 1960+)? If you're at or past your Required Beginning Date, you must take your annual RMD from the old plan before executing the rollover. RMDs cannot be rolled over — attempting to roll an RMD into an IRA creates an excess IRA contribution.²

If none of these apply, proceed. If one or more apply, read the linked guide or talk to an advisor before initiating anything.

Step-by-step: how to execute the rollover

Step 1 — Open (or identify) the destination IRA

Before contacting your old plan, you need a receiving account. If you don't have a traditional IRA, open one at a brokerage of your choice (Fidelity, Vanguard, Schwab, and others all work). This takes 10–15 minutes online; most brokerages will walk you through it. You don't need to fund it — it just needs to exist with an account number ready to give the old plan.

If you already have a traditional IRA, you can roll into it. A direct rollover from a 401(k) into an existing IRA is permitted and does not count toward the one-per-year limit that applies to IRA-to-IRA rollovers.¹

Commingling vs. keeping separate: There's no legal requirement to keep rollover funds in a separate IRA. However, some people prefer a separate account for clarity — particularly if they may want to do a reverse rollover back into a future employer's plan (most plans only accept rollovers of pre-tax funds, and a commingled account with nondeductible contributions can complicate the paperwork).

Step 2 — Contact your old plan and request a direct rollover

Call or log in to your old 401(k) provider. Every major plan administrator (Fidelity NetBenefits, Vanguard Plan Access, Empower, Principal, TIAA, etc.) has a distribution or rollover section. The key words to use:

"I want to request a direct rollover to a traditional IRA. I do NOT want a distribution payable to me."

If the representative suggests sending you a check or asks whether you want the money sent to you, clarify again: you want the funds wired or sent via check payable to the new custodian FBO (for benefit of) your name — not payable to you directly. An "FBO check" mailed to you is still a direct rollover; a check payable to you personally is an indirect rollover subject to 20% mandatory withholding.³

Step 3 — Complete the plan's distribution form

You'll receive (or download) a distribution request form. Key fields to fill out correctly:

Distribution type: Select "Direct Rollover to IRA" (not "hardship," not "in-service," not "lump sum distribution")
Destination account: Your new IRA custodian name, routing number, account number (or mailing address for check-based transfers)
Amount: Usually "full account balance" unless you're doing a partial rollover
Withholding election: 0% — mandatory withholding does not apply to direct rollovers³

Many plans also require a Medallion Signature Guarantee or spousal consent (if you're married and the plan is subject to ERISA joint-and-survivor rules). Your plan's form instructions will specify. Spouses must sign or consent in writing — this protects the non-participant spouse's survivor rights.

Step 4 — Wait for processing

Plan processing times vary widely:

Plan type / custodian	Typical processing time
Large national custodian (Fidelity, Vanguard, Schwab, Empower)	5–15 business days
Mid-size plan administrators (Principal, TIAA, MassMutual)	10–20 business days
Small employer plans (insurance-company platforms, older platforms)	3–6 weeks, sometimes longer
Wire transfer (institution-to-institution)	1–3 business days after plan approval
Check mailed to IRA custodian or to you (FBO)	3–10 days transit after plan issues

During this window, your funds are typically liquidated to cash inside the old plan (or all positions are sold). You will not be invested in either place during transit. In most cases this is days — not a significant market timing concern — but it's worth being aware of on volatile days.

Step 5 — Confirm receipt and invest the funds

Once the transfer arrives, your IRA custodian will deposit the funds as cash. They do not automatically invest it. Log in and allocate to your chosen investments — an index fund, target-date fund, or whatever your strategy calls for.

You'll receive a Form 1099-R from your old plan in January of the following year. The distribution code in Box 7 should be "G" — indicating a direct rollover. This is non-taxable. Your new IRA custodian will also issue a Form 5498 confirming the rollover contribution. Report the rollover on Form 1040 Line 5a (gross distribution) and 5b (taxable amount: $0 for a direct rollover to traditional IRA). Keep both forms.

Step 6 — Post-rollover housekeeping

Update beneficiary designations. Beneficiaries do not transfer from the old 401(k). You must re-designate on the new IRA. This is not automatic and is often overlooked.
Verify the full balance transferred. Occasionally a fractional share or dividend payment arrives after the main transfer. Check after 30 days.
Cancel any automatic contributions. If payroll deductions were going into the old plan (unlikely after termination, but possible with in-service rollovers), confirm they've stopped.
Update your asset allocation. The old plan's investment menu is gone. Make sure you've intentionally chosen your new investments — don't leave it sitting in a money market fund.

What if you accidentally received the check made out to you?

If your old plan sent you a check payable to you directly (an indirect rollover), you have 60 days from the date you received it to deposit the full original balance into an IRA to avoid taxes.¹

The problem: the plan withheld 20% federal income tax before cutting the check. If your distribution was $200,000, the plan sent you $160,000 and forwarded $40,000 to the IRS. To avoid paying tax on the $200,000 distribution, you must deposit the full $200,000 — including the $40,000 you don't have. You'd need to come up with $40,000 from savings, deposit it all, and then recover the $40,000 as a refund or credit on your tax return.

If you can't make up the withheld amount, only the portion you deposit avoids taxation. The rest is treated as a distribution — taxable as ordinary income, plus 10% early withdrawal penalty if you're under 59½.

If you miss the 60-day window due to circumstances beyond your control (hospitalization, postal delay, financial institution error, natural disaster), you may qualify for an automatic waiver under Rev. Proc. 2016-47 — a self-certification procedure that doesn't require an IRS ruling. This is a narrow exception with strict requirements. A tax advisor can help you determine if you qualify.

When a traditional IRA rollover is the right move — and when it's not

Situation	Traditional IRA rollover	Better alternative
Need access before 59½ and left job at 55+	Forfeits Rule of 55	Leave in old plan or roll only partial amount
Low-basis employer stock (NUA opportunity)	Converts appreciation to ordinary income	NUA distribution of employer stock, roll rest to IRA
You do or plan to do Backdoor Roth	Pro-rata rule taxes part of conversion	Roll to new employer's 401(k) instead
Outstanding 401(k) loan balance	Loan becomes taxable offset distribution	Repay loan first, or roll offset amount within deadline
You're age 73+ and haven't taken this year's RMD	RMD amount cannot be rolled; excess contribution if you try	Take the RMD first, then roll remaining balance
All other cases (fund quality, consolidation, Roth conversion access)	Usually the right move	—

A real example: $480,000 leaving a corporate plan at 57

Marcus, 57, left a large-company 401(k) with a $480,000 balance after being laid off. He has no employer stock and no outstanding loan. His new job offers a 401(k) with mediocre fund options.

His decision: he left the money in the old plan for six months (to preserve the Rule of 55 option while he assessed whether he'd need early withdrawals), then executed a direct rollover to a traditional IRA at Fidelity after deciding he could bridge income through age 59½ with taxable savings. The rollover: $0 in taxes, completed in 12 business days, no withholding. He updated beneficiaries, confirmed all shares arrived, and allocated to a three-fund portfolio.

The key move he didn't make: he avoided doing a nondeductible IRA contribution in the same year as the rollover, which would have created a pro-rata complication later when he wanted to explore partial Roth conversions. By keeping the IRA purely pre-tax, his future conversion math stays clean.
