How to Roll Over a 401(k) Without Paying Taxes

The cleanest way to roll over a 401(k) without paying taxes is a direct trustee-to-trustee transfer: your old plan sends the money straight to your new retirement account, you never touch it, nothing is withheld, and the IRS treats the whole amount as a non-taxable transfer. The account on the receiving end has to match the tax type of the account on the sending end (pre-tax to pre-tax, Roth to Roth), and a few categories of money inside your 401(k) can’t be rolled at all. Get those two things right and the transfer is tax-free.¹

Ask for a Direct Rollover, Not a Check

In a direct rollover, the funds move from your 401(k) plan to the receiving account through a trustee-to-trustee transfer. The check, if there is one, is made payable to the new custodian “for the benefit of” you. That “FBO” language is what tells the IRS the money is moving between qualified accounts rather than being paid out to you. No federal tax is withheld, and the full balance keeps its tax-deferred status.¹

An indirect rollover is the opposite. The plan sends the distribution to you, and you have 60 days to redeposit it into an eligible retirement account. Two problems come with this path. First, the plan administrator must withhold 20% of the taxable portion for federal taxes before sending you anything. On a $100,000 balance, you receive $80,000. To keep the entire $100,000 out of your taxable income, you have to deposit $100,000 in the new account, which means covering the missing $20,000 from your own pocket and waiting to recover it as a refund when you file. Second, if the full amount isn’t in the new account within 60 days, whatever is short becomes a taxable distribution, with a 10% early withdrawal penalty on top if you’re under 59½.²

For a tax-free result, always ask for the direct method. The indirect route only makes sense in the narrow case where you actually need short-term use of the cash and you have savings on hand to replace the 20% withholding.

If You Missed the 60-Day Deadline

Missing the deadline on an indirect rollover makes the entire distribution taxable for the year, plus the 10% penalty if you’re under 59½. The IRS does allow relief in specific circumstances.

Under Revenue Procedure 2020-46, you can self-certify a late rollover by giving the receiving plan or IRA trustee a written statement explaining why the deadline was missed. Twelve reasons qualify, including a financial institution error, a lost or misplaced rollover check, a postal error, a deposit into an account you mistakenly believed was eligible, serious illness or a death in the family, severe damage to your principal residence, and paperwork delays from the distributing plan despite your reasonable efforts.³ You have to complete the rollover within 30 days after the reason for the delay ends. Self-certification isn’t binding on the IRS; they can still challenge it on audit. But it lets the receiving institution accept the late contribution as a valid rollover.⁴

There’s also an automatic waiver when the financial institution received your funds inside the 60-day window, you followed all their deposit instructions, and the failure to complete the deposit on time was entirely the institution’s fault. In that case, you have up to a year from the start of the 60-day period to finish the rollover.⁴

Match the Tax Type of the Two Accounts

The rollover stays tax-free only when the receiving account has the same tax status as the source. Mixing types either triggers an immediate tax bill or works against you later.

Traditional 401(k) to Traditional IRA or a New 401(k)

Pre-tax contributions and their earnings must land in another pre-tax account, either a traditional IRA or a new employer’s traditional 401(k), to stay tax-free. This is the default path for most rollovers.²

Roth 401(k) to Roth IRA

A designated Roth account inside your 401(k) rolls tax-free into a Roth IRA. One detail matters: the five-year clock for tax-free withdrawal of Roth IRA earnings runs from the year you first funded any Roth IRA, not from the year you had the Roth 401(k). If this rollover opens your first Roth IRA, the clock starts now.⁵

Traditional 401(k) to Roth IRA

You can move pre-tax 401(k) money into a Roth IRA, but the IRS treats this as a Roth conversion. The converted amount becomes ordinary income for the year, taxed at your current bracket. No early withdrawal penalty applies, but this is not a tax-free rollover. It’s a deliberate decision to pay tax now in exchange for tax-free growth later.

What You Cannot Roll Over

Some amounts inside a 401(k) aren’t eligible for rollover, and trying to roll them creates its own tax problem. The IRS excludes:²

Required minimum distributions. Once you reach RMD age (73 for those born between 1951 and 1959, 75 for those born in 1960 or later), the year’s RMD must come out as taxable income before you roll anything.
Hardship distributions.
Substantially equal periodic payments calculated over your life expectancy.
Corrective distributions of excess deferrals and their earnings.
Loan amounts treated as distributions, which follow their own rules discussed below.

The RMD exclusion is the one that trips people up most. If you’re rolling over in a year an RMD is due, take the RMD first and then move the rest. Rolling the RMD amount into an IRA counts as an excess contribution to that IRA and carries its own penalty.

If You Have an Outstanding 401(k) Loan

Leaving your employer with an unpaid 401(k) loan usually causes the balance to be treated as a distribution, called a plan loan offset. Without action, that amount becomes taxable income, plus the 10% penalty if you’re under 59½.

A qualified plan loan offset gets an extended deadline. Rather than 60 days, you have until your tax filing due date for that year, including extensions. Filing an extension typically pushes the deadline from April 15 to October 15.⁶ To take advantage, contribute an amount equal to the offset from other funds into an IRA or another eligible plan by that deadline. That contribution effectively replaces the loan balance and keeps the distribution non-taxable.

How to Actually Execute the Transfer

Open the destination account first if you don’t already have one. If you’re rolling into a new employer’s plan, confirm with that plan administrator that they accept incoming rollovers, because not all plans do. If you’re rolling into an IRA, any major brokerage can set one up.

Have the receiving custodian’s exact legal name, the new account number, and the rollover processing mailing address in hand before you call your current plan. Then contact your existing plan administrator, through the employer’s HR portal or the plan’s service line, and request a direct rollover. You’ll complete a Distribution Election or Rollover Request form. The check’s “payable to” line should read something like “Fidelity Investments FBO [Your Name],” substituting your receiving institution’s name.⁷ That “FBO” language is what marks the transfer as a rollover instead of a distribution.

Most plan administrators process the request in five to ten business days. If a physical check is issued, forward it to the receiving institution promptly with any required deposit slips. Some brokerages accept mobile deposit for rollover checks; others require the original by certified mail.

Report the Rollover on Your 1040

Your old plan will issue Form 1099-R for the year of the distribution. A direct rollover from a traditional 401(k) to another qualified plan or a traditional IRA shows distribution code G in Box 7. A direct Roth 401(k) to Roth IRA rollover shows code H.⁸

On Form 1040, report the total distribution on Line 5a and, if you rolled the entire amount, enter zero on Line 5b as the taxable amount. Indicate on the return that the distribution was a rollover.⁹ Skipping this step is a common mistake: the IRS sees a large distribution on the 1099-R with no taxable-amount explanation and sends a notice for the full tax.

For an indirect rollover where the 1099-R shows a taxable distribution rather than a rollover code, report the gross amount on Line 5a and the taxable portion on Line 5b. If you redeposited the full amount within 60 days, Line 5b is zero.

If Your 401(k) Holds Employer Stock, Read This Before Rolling

Rolling everything into an IRA is not always the best move when your 401(k) holds shares of your employer’s stock. A tax rule called Net Unrealized Appreciation can save significant tax on those shares.

Under NUA, you take a lump-sum distribution of the company stock into a regular taxable brokerage account rather than rolling it into an IRA. You pay ordinary income tax on the plan’s cost basis in the shares in the year of distribution. The appreciation above that basis is taxed at long-term capital gains rates when you sell, regardless of how long you hold after the distribution.¹⁰ Ordinary rates run up to 37%; long-term capital gains rates are 0%, 15%, or 20%. On highly appreciated stock, the gap is large.

NUA treatment requires a lump-sum distribution of your entire vested balance within a single tax year, triggered by separation from service, reaching age 59½, disability, or death. You can still roll the non-stock portion into an IRA and apply the NUA election only to the shares. If the stock hasn’t appreciated much, rolling it into an IRA for continued deferral usually wins.

Boundaries Worth Knowing

Non-spouse inherited 401(k)s follow different rules. A non-spouse beneficiary cannot roll the account into their own IRA. The only option is a direct trustee-to-trustee transfer into an inherited IRA titled in the deceased person’s name for your benefit.² Under the SECURE Act’s 10-year rule, most non-spouse beneficiaries who inherited in 2020 or later must empty the account by the end of the tenth year following the original owner’s death, with annual distributions required during those ten years if the original owner had already started RMDs. A surviving spouse can roll the inherited 401(k) directly into their own IRA and treat it as their own.

Once your money is in an IRA, a separate limit takes effect. You can only do one indirect, 60-day IRA-to-IRA rollover in any 12-month period, and the limit applies across all your IRAs combined. It does not apply to your initial 401(k)-to-IRA rollover, and it does not apply to direct trustee-to-trustee transfers between IRAs.¹¹ Violating it turns the second rollover into a taxable distribution.
