A 90-day permissible withdrawal from a 401(k) lets you undo an automatic enrollment by pulling your default contributions back out within 90 days of your first payroll deduction. You get your money back, adjusted for any investment gains or losses, you owe ordinary income tax on the amount, and you avoid the 10% early-withdrawal penalty that normally applies before age 59½.1Office of the Law Revision Counsel. 26 USC 414 Definitions and Special Rules The same option applies to 403(b) plans that use automatic enrollment.
When the 90 Days Start
The clock starts on the date of your first default elective contribution. Not your hire date. Not the date you got the enrollment notice. The date the first deduction actually came out of a paycheck. Your election to take the withdrawal has to reach the plan no later than 90 days after that first deduction.1Office of the Law Revision Counsel. 26 USC 414 Definitions and Special Rules
The deadline is strict. Plan administrators enforce it to protect the plan’s tax-qualified status, and there is no hardship extension.
Only money that was withheld through the automatic default qualifies. If at any point you logged into the plan portal and picked a contribution rate, raised the default, or lowered it, you made an affirmative election. Contributions made under an election you chose are not eligible for a permissible withdrawal. The provision is built for money that came out because you did nothing.
How to Request the Withdrawal
Pull your pay stubs and find the exact date of the first automatic deferral. Count forward 90 days from that date. Then contact your HR department or the plan’s third-party administrator and ask for the permissible withdrawal request form. Some plans handle it through an online portal; others use paper.
The form will ask for your plan ID, Social Security number, and the amount you want returned. Confirm the mailing address on file, because many administrators cut a paper check. Some offer direct deposit, which is faster.
Once the plan receives your election, the distribution follows the plan’s ordinary processing timeline, generally one to three weeks.2eCFR. 26 CFR 1.414(w)-1 Permissible Withdrawals From Eligible Automatic Contribution Arrangements Your future automatic contributions also stop. Under the regulations, the plan must cease default deferrals no later than the earlier of the pay date for the second payroll period after your election, or the first pay date at least 30 days after the election.
Your employer should have sent you a written notice before auto-enrolling you, explaining the default rate, how to opt out, and how to take a permissible withdrawal.3Internal Revenue Service.

What You Get Back and What You Give Up
The distribution equals every default contribution from your first deduction through the effective date of your withdrawal election, adjusted for any investment gains or losses during that stretch.1Office of the Law Revision Counsel. 26 USC 414 Definitions and Special Rules If the default investments gained value, you receive more than what was deducted. If they lost value, you receive less.
Any employer matching contributions tied to those automatic deferrals are forfeited. The match goes back into the plan’s forfeiture account and can be used toward plan expenses or allocated to other participants. You get your own money and its earnings, nothing else.
How the Distribution Is Taxed
The withdrawn amount counts as taxable income for the year you receive it, at the ordinary federal income tax rates that apply to your total income.4Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 The 10% early-distribution penalty under Section 72(t) does not apply. For a worker under 59½, this is the only practical way to pull money out of a 401(k) or 403(b) without that extra penalty.1Office of the Law Revision Counsel. 26 USC 414 Definitions and Special Rules
Your plan administrator will report the payment on Form 1099-R with distribution Code 2, which signals to the IRS that an early-distribution exception applies.5Internal Revenue Service. Instructions for Forms 1099-R and 5498 The form arrives early the following year and goes with your tax return.
If your plan auto-enrolled you into a designated Roth account instead of a pre-tax account, the contribution portion of the withdrawal is not taxed again because it was already after-tax. Only the earnings portion is taxable, and the 1099-R will show only earnings in box 2a.5Internal Revenue Service. Instructions for Forms 1099-R and 5498 Over a few weeks or months, that earnings figure is usually small, so the tax hit on a Roth permissible withdrawal is often minimal.
If You Miss the 90-Day Window
Once the 90 days pass, the permissible withdrawal option is gone. Your contributions stay in the plan. You can change your contribution rate to 0% going forward to stop future deductions, but the money already in the account is subject to the plan’s normal distribution rules. That generally means no access until age 59½, separation from the employer, disability, or another qualifying event. A standard early distribution before 59½ would trigger the same 10% penalty this provision was designed to avoid.
That is why the date on your first pay stub matters. If you were auto-enrolled and are not sure you want to participate, count the 90 days from that first deduction and decide inside that window. Waiting to sort it out later is the most common way people lose the option.
Contributing Again After a Withdrawal
Taking a permissible withdrawal does not lock you out of the plan. The federal regulations do not impose a waiting period before you can start contributing again.6eCFR. 26 CFR 1.414(w)-1 Permissible Withdrawals From Eligible Automatic Contribution Arrangements The plan document controls the specifics. Some plans let you make a new affirmative election at any time; others may reapply the automatic default if your prior election lapses. Ask your plan administrator how re-enrollment works.
Any future contributions you actively elect are voluntary, and voluntary contributions never qualify for another permissible withdrawal. The 90-day option is a one-time safety net for money you were defaulted into, not a recurring feature you can use each year.
