How to Close a 401(k): Rules, Rollovers, and Withholding

To close a 401(k), you request a full distribution from the plan administrator after a qualifying event — usually leaving the employer — and choose whether to roll the balance into another retirement account or take it as cash. The mechanics are straightforward. The tax consequences are not, and knowing how to close a 401(k) without a costly mistake mostly comes down to how you route the money on its way out.

When You’re Allowed to Close the Account

Federal rules tie 401(k) distributions to specific life events. You can’t empty the account on a random Tuesday while still employed at the sponsoring company. The most straightforward path opens when you separate from the employer, whether you quit, get laid off, or retire. Once that separation is final, you gain the right to move your vested balance out of the plan.¹

If you’re still working for the employer, you generally can’t take a full distribution of your salary deferrals until age 59½.² Some plans also allow distributions for hardship, disability, or when the employer terminates the plan entirely. If the employer shuts down the whole 401(k) program, participants become immediately 100% vested and the administrator must distribute all assets as soon as administratively feasible, typically within a year.³

The Rule of 55

If you leave your job during or after the calendar year you turn 55, you can take distributions from that employer’s 401(k) without the 10% early withdrawal penalty. This is often called the Rule of 55, and it only applies to the plan held by the employer you just separated from, not older 401(k) accounts from previous jobs.⁴ The threshold drops to age 50 for qualifying public safety employees such as law enforcement officers, firefighters, and corrections officers.

Check Vesting First

Your salary deferrals are always 100% yours. Employer matching and profit-sharing dollars are a different story. Many plans use a vesting schedule that gradually increases your ownership of those contributions over several years, and if you leave before you’re fully vested, you forfeit the unvested portion.¹ Look at your vesting schedule before you assume the whole balance is what you’ll walk away with.

Decide How to Take the Money Before You File Paperwork

Closing the account (the balance going to zero) is not the same as cashing out. The IRS recognizes four choices after you leave a job, and only one of them triggers immediate taxes.⁵

Leave it in the former employer’s plan. Balances of $7,000 or more can usually stay put, keep growing tax-deferred, and buy you time to decide.
Roll it into your new employer’s plan, if the new plan accepts incoming rollovers.
Roll it into an IRA. A traditional IRA rollover preserves tax deferral and opens a much broader investment menu. A rollover to a Roth IRA is possible, but you’ll owe income tax on the converted amount.
Cash out. You get the money directly, the plan withholds 20% for federal taxes, and if you’re under 59½ a 10% penalty stacks on top. This is the most expensive option for most people.

If you want the account closed but you’re not sure what to do with the money, a direct rollover to an IRA takes the balance to zero at the old plan while preserving every dollar.

Force-Out Rules for Small Balances

If your vested balance is under $1,000, your former employer can cut you a check and close the account without asking. For balances between $1,000 and $7,000, the plan can force the money out, but it must roll those funds into an IRA in your name rather than sending cash. The $7,000 threshold was raised from $5,000 under SECURE 2.0, effective for distributions after December 31, 2023. Above $7,000, the administrator needs your consent before distributing anything.¹

Clear These Loose Ends Before You Submit

Outstanding 401(k) Loans

If you borrowed from the plan and still owe money when you leave, the unpaid balance becomes a ticking clock. Most plans require full repayment within a short window after separation, often 60 to 90 days depending on the plan terms. If you can’t repay, the remaining balance is treated as a distribution and reported on Form 1099-R.⁶ That distribution is taxable income, and the 10% penalty applies if you’re under 59½. You can roll the outstanding loan amount into an IRA or another eligible plan by your tax filing deadline (including extensions) for the year the loan was treated as distributed, but you have to come up with that cash from other sources.⁷

Required Minimum Distributions at 73

If you’ve reached age 73, you must take your required minimum distribution for the year before rolling over or closing the account. RMDs cannot be rolled over. Your first RMD is due by April 1 of the year after you turn 73, and every subsequent RMD is due by December 31.⁸ When you’re closing the account, the administrator will usually split the distribution, satisfying the RMD first as taxable income and processing the rest as a rollover or cash-out.

Spousal Consent

If you’re married and your plan offers annuity-style distribution options, federal law requires your spouse’s written consent, witnessed by a notary or plan representative, before the plan can pay your benefit in a different form.⁹ Some plans also require spousal consent if you name someone other than your spouse as primary beneficiary. Not every plan triggers this, but if yours does and you skip it, your distribution request will bounce back.

What You’ll Need to Submit the Request

Gather everything before you contact the plan administrator. Chasing missing details mid-process is the most common reason closures stall.

Your plan participant ID, usually on account statements or the plan’s online portal.
The distribution election form from your administrator (Fidelity, Vanguard, Schwab, or similar), where you specify direct rollover, indirect rollover, or cash.
Receiving account details for rollovers: the exact name of the institution, the account number, and the mailing address. For a rollover into a new employer’s 401(k), you’ll also need that plan’s name and plan number.
Bank routing and account numbers for a cash distribution paid by direct deposit.
Tax withholding elections. For cash distributions, 20% federal withholding is mandatory and cannot be waived, but you can elect additional withholding if you expect to owe more.

Set up the destination account first. If you’re rolling into a new IRA, open it and get the account number before submitting anything. Administrators reject forms that reference accounts that don’t yet exist.

Submitting and Processing the Request

Most administrators offer an online portal that walks you through the distribution type, destination account details, tax withholding elections, and final confirmation. Some plans still require paper forms, and a few require notarized signatures, particularly for spousal consent or distributions above certain dollar thresholds.

After submission, the administrator runs a compliance review to confirm you’re eligible and the paperwork is complete. Watch your email or portal notifications during this stage. Once approved, the administrator liquidates your investments (mutual funds, target-date funds, stable value funds) and converts them to cash before sending the money out.

One caveat: plans occasionally enter a blackout period during administrator transitions or plan mergers, during which distribution requests are paused. Federal rules require advance notice of these blackouts.¹⁰ Ask about any upcoming blackout before you start.

Taxes and Penalties If You Cash Out

This is where most people underestimate the cost. A 401(k) cash distribution is taxed as ordinary income, stacked on top of whatever else you earned that year.¹¹

The 20% Withholding Is Not the Final Bill

When you take a cash distribution rather than a direct rollover, the plan must withhold 20% for federal income tax. You cannot opt out.¹² On a $100,000 account, you’d receive $80,000 and the other $20,000 goes to the IRS.

That 20% is just a prepayment toward your actual tax bill, not the final number. If the distribution pushes you into the 24% or 32% bracket, you owe the difference when you file. State income taxes may also apply. Your plan will send you a Form 1099-R by January 31 of the following year reporting the distribution.

The 10% Early Withdrawal Penalty

If you’re under 59½ when you take the distribution, an additional 10% penalty tax applies to the taxable amount.⁴ Combined with income tax, this can eat 30% to 40% of your balance before you spend a dime. Exceptions exist, including the Rule of 55, disability, and substantially equal periodic payments, but most people cashing out after a job change don’t qualify.

Direct Rollovers Avoid All of This

If you choose a direct rollover, where the check goes straight from your old plan to a new 401(k) or IRA, no withholding applies and no taxes are due. The 20% withholding rule specifically exempts direct rollovers.¹³ The account still closes, but the money continues its tax-deferred life in the new account.

Roth 401(k) Balances

If part or all of your balance is in a designated Roth account, tax treatment depends on whether the distribution is qualified. A distribution is qualified, and completely tax-free, if you’ve held the Roth account for at least five years and you’re at least 59½ (or the distribution is due to disability or death).¹⁴ Otherwise, your original contributions come out tax-free, but earnings are taxable and potentially subject to the 10% penalty. Accounts with both traditional and Roth balances are typically processed as separate distributions.

The 60-Day Indirect Rollover Trap

An indirect rollover is when the plan sends the distribution check to you personally, and you’re responsible for depositing the money into a new retirement account within 60 days. Miss that deadline and the entire amount becomes a taxable distribution, plus the 10% penalty if you’re under 59½.¹⁵

The math makes this worse. Because the plan withholds 20% before sending you the check, you only receive 80% of your balance. To complete a full rollover and avoid tax on the withheld portion, you have to deposit the full original amount, making up the 20% difference from other savings. On a $50,000 account, you receive $40,000 and need to come up with another $10,000 to deposit $50,000 within 60 days. Deposit only the $40,000 you received and the missing $10,000 is treated as a taxable distribution.¹⁵ You’d get the $10,000 back as a tax credit at filing, but only after fronting it yourself. A direct rollover sidesteps the whole trap.

Timeline, Fees, and the 1099-R

Plan on roughly 7 to 14 business days from approval to receiving funds, though some administrators move faster and others slower. The process breaks into compliance review, investment liquidation, and fund transfer. Stable value funds and certain alternative investments may take longer because of their own withdrawal restrictions.

Cash distributions arrive by direct deposit or mailed check. For direct rollovers, the check is made payable to the receiving institution “for the benefit of” you, and that payee format is what keeps the transfer tax-free. Once the funds leave, the account status flips to closed.

Some plans charge an administrative fee for processing the distribution. There’s no federal cap; the law only requires the fee be reasonable. Amounts vary widely and the fee is usually deducted from your balance. Ask your administrator before you start.

You’ll receive Form 1099-R by January 31 of the year after the distribution, reporting the total distributed, the taxable portion, and any withholding. Keep it for your federal tax return. If you did a rollover, the 1099-R will show the distribution with a code indicating it was rolled over, but you should still report it on your return to avoid an IRS inquiry.
