How to Roll Over 401(k) to IRA: 2026 Step-by-Step Guide

When you leave a job, your 401(k) doesn’t automatically follow you — and figuring out how to roll over a 401k to an IRA is one of the smartest moves you can make after a job change. Done correctly, a rollover keeps your retirement savings growing tax-deferred, usually gives you far more investment choices than your old employer’s plan, and costs you nothing in taxes or penalties.

But the details matter enormously. One wrong choice — like having the check made out to you instead of your new IRA custodian — triggers a mandatory 20% federal withholding and starts a 60-day clock you cannot afford to miss. This guide walks through your four options, the exact steps for a clean rollover, and the traps that turn a simple transfer into a surprise tax bill.

Your 4 Options for an Old 401(k)

You generally have four choices for a 401(k) from a former employer, and there is no universal deadline forcing you to pick quickly. The one exception is small balances: under SECURE 2.0, plans can force out accounts of $7,000 or less (for distributions after December 31, 2023) — balances under $1,000 may simply be mailed to you as a check.

For most people, rolling over to an IRA wins on flexibility and cost — but only if you execute it as a direct rollover, which is where most people go wrong.

How to Roll Over a 401k to an IRA: Direct vs. Indirect

There are two ways to move the money, and the tax consequences are completely different. The IRS spells this out plainly in its 401(k) Resource Guide: with a direct transfer, no taxes are withheld; with a distribution paid to you, 20% withholding is mandatory even if you fully intend to roll it over.

Option A: Direct Rollover (Trustee-to-Trustee) — the Recommended Way

In a direct rollover, your old plan sends the money straight to your new IRA custodian. You never touch it. Nothing is withheld, and no 60-day clock starts ticking. Here are the steps:

1. Open a traditional IRA (or a Roth IRA if you’re rolling over Roth 401(k) money) with a brokerage of your choice — Fidelity, Charles Schwab, and Vanguard are common picks.
2. Contact your old 401(k) plan administrator and request a “direct rollover” to your IRA. Have your new account number and the custodian’s transfer instructions ready.
3. Confirm how the funds will move. Some plans wire the money; others mail a check made payable to the new custodian, such as “Fidelity FBO [Your Name].” Either way, as long as the check isn’t payable to you, it’s a direct rollover.
4. Confirm the deposit and invest it. Rollover cash often lands in a money-market sweep account — it won’t grow properly until you actually choose investments.
5. Report it at tax time. You’ll receive Form 1099-R. A direct rollover isn’t taxable, but it is reportable on your federal return.

Option B: Indirect Rollover — the 20% Withholding Trap

In an indirect rollover, the plan pays you first, and you redeposit the money into an IRA yourself. This is where the trap springs: the IRS requires your plan to withhold a mandatory 20% for federal income tax on any eligible rollover distribution paid directly to you — even if you tell them you’re going to roll it over.

Here’s the trap with real numbers. Say your old 401(k) holds $50,000:

• You receive a check for $40,000. The plan sends $10,000 to the IRS.
• To complete a fully tax-free rollover, you must deposit the entire $50,000 into your IRA within 60 days — which means coming up with $10,000 from your own savings to replace what was withheld.
• If you only deposit the $40,000 you received, the missing $10,000 is treated as a taxable distribution. If you’re under 59½, that $10,000 also gets hit with the 10% early withdrawal penalty.

You do eventually get credit for the withheld $10,000 when you file your tax return — but only if you fronted the money to complete the rollover. Miss that detail and a “simple” rollover becomes a tax bill plus a penalty. The lesson: almost always choose the direct rollover.

The 60-Day Rollover Rule, Explained

If you do an indirect rollover, IRS Topic No. 413 gives you 60 calendar days from the date you receive the distribution to get the money into another eligible retirement plan. Miss the deadline by a single day and whatever you didn’t redeposit is treated as a taxable distribution — plus the 10% early withdrawal penalty if you’re under 59½.

The IRS can waive the 60-day deadline in genuine hardship cases (serious illness, natural disaster, financial institution error), but waivers are never guaranteed. A direct rollover sidesteps the entire rule — there is no clock at all.

The One-Rollover-Per-Year Rule (and Why It Doesn’t Apply to Your 401(k))

You may have heard you’re limited to one rollover per year. Here’s the fine print most articles skip: that limit applies only to IRA-to-IRA indirect (60-day) rollovers, aggregated across every IRA you own in a rolling 12-month period — a rule the IRS has enforced this way since 2015.

It does not apply to:

• Direct trustee-to-trustee transfers (unlimited)
• Rollovers from a 401(k) to an IRA — which is exactly what you’re doing here
• Roth conversions

So rolling your old 401(k) into an IRA will never trip this rule. Where it does bite is IRA-to-IRA 60-day rollovers: a second one within 12 months is fully taxable, can’t be waived or corrected, and can trigger a 6%-per-year excess contribution tax until fixed, as Ed Slott’s analysis explains. Another reason to prefer direct transfers for everything.

What About Roth 401(k) Money?

Not all 401(k) money is pre-tax, so match the account types correctly:

• Roth 401(k) to Roth IRA: tax-free, as long as it’s a direct rollover. No withholding, no tax bill.
• Pre-tax 401(k) to traditional IRA: tax-free. Your money keeps growing tax-deferred, exactly as before.
• Pre-tax 401(k) to Roth IRA: this is a Roth conversion, and the converted amount counts as taxable income in the year you convert. There’s no income limit on conversions, but plan for the tax bill before you do it.

What to Do If Your Old Plan Mails You a Check

Many plans still mail physical checks. Don’t panic — just read the payee line carefully:

• Payable to your new IRA custodian (for example, “Charles Schwab FBO Jane Smith”): this is still a direct rollover. Forward or deposit it with your custodian promptly. Don’t let it sit in a drawer for months.
• Payable to you personally: this is an indirect rollover. The 20% has been withheld and your 60-day clock is already running from the day you received it. Deposit the full original distribution amount — adding the withheld portion from your own savings — within 60 days.

And if a check arrived out of nowhere for a small balance, that’s likely a SECURE 2.0 force-out: plans may cash out balances under $1,000 directly to you, or sweep balances between $1,000 and $7,000 into a default IRA the plan chose. You can still roll that default IRA into an account of your choosing.

6 Mistakes That Trigger Taxes and Penalties

1. Taking an indirect rollover when a direct one was available. There’s almost no reason to touch the money yourself.
2. Forgetting to replace the 20% withholding out of pocket. The withheld amount only stays tax-free if you redeposit it too.
3. Missing the 60-day deadline on an indirect rollover — even by one day.
4. Rolling pre-tax money into a Roth IRA without budgeting for the conversion tax bill.
5. Trying to roll over ineligible distributions. Required minimum distributions and hardship withdrawals can’t be rolled over, per the IRS rollover rules.
6. Cashing out “just this once.” Between income tax and the 10% early withdrawal penalty, cashing out is the most expensive option on the menu — and if you’re raiding retirement to cover bills, that’s usually a sign your emergency fund needs attention first.
