What Is a 401(k) Rollover? 60-Day Rule, 20% Withholding, and Exceptions

A 401(k) indirect rollover is a distribution paid to you personally that you then redeposit into another retirement account within 60 days to keep its tax-deferred status. The plan administrator withholds 20% for federal taxes before cutting the check, so to move the full balance without triggering tax, you have to make up that 20% from your own pocket and deposit the original pre-withholding amount into the receiving account before the deadline. Miss the window or come up short, and the IRS treats the gap as a taxable distribution, often with a 10% penalty on top.

The 60-Day Deadline

Federal law gives you exactly 60 days from the date you receive the distribution to deposit it into another eligible retirement account. Hit day 61 without completing the deposit and the IRS treats the entire unredeposited amount as a taxable distribution for that year. There is no grace period and no automatic extension.

The clock starts when you actually receive the funds, not when you request them. Mailing delays can shrink your working window by a week or more, so tracking the delivery date of the check is worth the effort. The difference between day 59 and day 61 can cost thousands in taxes and penalties.

Why 20% Goes Missing From Your Check

When a plan administrator pays a distribution directly to you instead of transferring it to another retirement account, federal law requires them to withhold 20% for income taxes. If your 401(k) balance is $50,000, you receive a check for $40,000. The other $10,000 goes to the IRS as a tax prepayment.

To complete a full rollover and owe nothing extra, you have to deposit the entire original amount, $50,000 in this example, into the new retirement account within 60 days. That means finding $10,000 from savings or another source to replace what was withheld. You get that $10,000 back when you file your tax return as part of your refund, but you need it up front. If you only deposit the $40,000 that actually landed in your account, the IRS treats the missing $10,000 as a permanent distribution. That triggers income tax and, if you’re under 59½, the 10% early withdrawal penalty on the shortfall.

You can request a withholding rate higher than 20% using IRS Form W-4R if you expect to owe more, but you cannot go below 20% on an indirect rollover.

Where the Money Can Go

The law defines a specific list of eligible retirement plans that can receive rollover money. After leaving a job, the most common destination is a traditional IRA. You can also roll funds into a new employer’s 401(k) if that plan accepts incoming rollovers, or into a 403(b) or governmental 457(b).

Depositing the check into a regular brokerage or savings account ends the tax-deferred status immediately, and the whole distribution becomes taxable income for the year.

Roth 401(k) Funds

If your 401(k) includes a designated Roth account, that money can only roll into another designated Roth account or a Roth IRA. The 20% mandatory withholding still applies to indirect rollovers of Roth funds even though the underlying contributions were made with after-tax dollars. You still have to replace the withheld amount and deposit the full distribution within 60 days to avoid tax consequences on the earnings portion.

SIMPLE IRA Two-Year Rule

SIMPLE IRAs carry a waiting period worth flagging. During the first two years after you start participating in a SIMPLE IRA plan, that money can only move to another SIMPLE IRA. Rolling it into a 401(k) or traditional IRA inside the two-year window triggers income tax plus a 25% early withdrawal penalty, not the usual 10%. After two years, SIMPLE IRA funds move freely to traditional IRAs, 401(k)s, 403(b)s, and governmental 457(b) plans.

Requesting the Distribution and Completing the Deposit

Start with your current plan administrator or your employer’s retirement plan portal. Most plans offer a distribution request form you can download or complete online. On the form, select “indirect rollover” or “lump sum distribution” as the distribution type. The exact label varies by plan.

You’ll also see a section on federal tax withholding, locked at a 20% minimum for indirect rollovers. Have the name, address, and account number of your receiving institution ready so the redeposit step goes smoothly once the check arrives.

After the plan processes the request, you’ll receive a check made payable to you. That payee is what makes it an indirect rollover rather than a direct transfer. Once the check arrives, deposit the full original distribution amount (the check plus outside cash covering the 20% withheld) into the new retirement account. When you make the deposit, explicitly tell the receiving institution it’s a rollover contribution so they code it correctly on the IRS forms they file on your behalf.

What It Costs to Miss the Deadline

A failed rollover hits you twice. First, the entire unredeposited amount gets added to your gross income for the year. Depending on the size of the distribution, that income spike can push you into a higher tax bracket, raising the rate on all your other income too.

Second, if you’re under 59½, the IRS adds a 10% additional tax on the taxable portion. On a $50,000 distribution where the rollover failed, that’s $5,000 in penalties on top of the income tax. Combined, ordinary income tax and the early distribution penalty can easily consume 30% to 40% of the account value.

Ways to Salvage a Late Rollover

If you missed the 60-day window for a qualifying reason, you have two options.

Self-Certification

Under IRS Revenue Procedure 2016-47, you can write a letter to the receiving plan administrator or IRA custodian certifying that you missed the deadline for one of these specific reasons:

  • Financial institution error caused the delay
  • The distribution check was lost and never cashed
  • You deposited funds into an account you mistakenly believed was an eligible retirement plan
  • Your principal residence suffered severe damage
  • You or a family member died or became seriously ill
  • You were incarcerated during the rollover window
  • Foreign restrictions or postal error delayed the transfer
  • The distributing institution delayed providing paperwork the receiving plan needed, despite your reasonable efforts to obtain it

You have to complete the rollover within 30 days after the qualifying reason no longer prevents you from acting. The IRS provides a model certification letter in the revenue procedure you can use word-for-word. Keep a copy in case the IRS questions the late rollover on audit.

Private Letter Ruling

If your situation doesn’t fit the self-certification categories, you can request a private letter ruling from the IRS asking them to waive the deadline. The current user fee is $3,500 as of 2026, and there’s no guarantee the IRS will grant the waiver. The IRS can also waive the requirement on its own when enforcing the deadline would be “against equity or good conscience,” such as after a federally declared disaster.

The One-Rollover-Per-Year Rule

The IRS limits you to one indirect rollover from an IRA to another IRA (or back to the same IRA) in any 12-month period. This restriction aggregates all your IRAs, traditional, Roth, SEP, and SIMPLE, and treats them as a single account for purposes of the limit. A second IRA-to-IRA indirect rollover within 12 months becomes fully taxable.

The rule does not apply to rollovers from an employer plan to an IRA. A 401(k)-to-IRA rollover, a 403(b)-to-IRA rollover, and a plan-to-plan rollover are all exempt from the one-per-year limit. You could roll over a 401(k) into an IRA in March and roll over another employer plan into a different IRA in September without violating the rule. The restriction targets only IRA-to-IRA transfers done through the indirect method.

Reporting the Rollover on Your Taxes

Even a clean indirect rollover generates paperwork. Your former plan administrator sends Form 1099-R reporting the distribution. The distribution code in Box 7 tells the IRS what type of payout it was: Code 1 (early distribution) if you’re under 59½, or Code 7 (normal distribution) if you’re 59½ or older. Box 4 shows the federal tax withheld.

The receiving institution files Form 5498 with the IRS the following year, reporting the rollover contribution in Box 2. That form confirms the money actually landed in a new retirement account.

On your Form 1040, report the total distribution amount on line 5a. On line 5b, enter the taxable amount, which should be zero if you completed the rollover in full, and write “ROLLOVER” next to it. The federal tax withheld gets reported on line 25b, where it counts toward your total tax payments for the year. If you replaced the withheld amount from outside funds, that money comes back as part of your refund.

Skipping this reporting step is a common mistake. The IRS receives the 1099-R showing a distribution. If your return doesn’t account for it, the automated matching system flags it as unreported income and generates a notice with a proposed tax bill.

When an Indirect Rollover Is the Wrong Move

For most people leaving a job, a direct rollover is simpler and safer. The plan administrator sends the money straight to your new IRA or 401(k) custodian. No 20% withholding, no 60-day clock, no need to come up with outside cash. You never touch the money, so there’s nothing to fumble.

An indirect rollover makes sense in a narrow set of circumstances: you need short-term access to the cash during the 60-day window, you’re consolidating accounts and want to handle the logistics yourself, or your former plan’s administrative process makes a direct transfer impractical. Outside those situations, the risk-reward tilts heavily toward direct transfers.

Two situations rule out the indirect method entirely. Non-spouse beneficiaries who inherit a 401(k) or IRA cannot perform a 60-day rollover at all; the only option is a direct trustee-to-trustee transfer into an inherited IRA. Depositing an inherited distribution check yourself makes the full amount taxable as ordinary income, and the mistake is irreversible. And if your 401(k) holds appreciated company stock, rolling it into an IRA (direct or indirect) permanently forfeits net unrealized appreciation treatment, which can otherwise let you pay long-term capital gains rates on the stock’s growth instead of ordinary income rates. Talk to a tax professional before initiating any rollover of employer stock.
