If retirement deductions started coming out of your paycheck without your say-so, you have two separate moves to make. To opt out of a 401(k) and reclaim contributions, change your deferral rate to 0% through your employer’s benefits portal to stop future deductions, then request a permissible withdrawal from the plan administrator within 90 days of your first paycheck deduction to get back what’s already been taken. Miss that 90-day window and the money generally stays in the account until you leave the job, reach 59½, or qualify for a hardship distribution.
Stop Future Contributions First
You can drop your contribution rate to 0% at any time. There is no annual open-enrollment period for turning off salary deferrals. Log into your employer’s benefits portal or contact the plan administrator and set the deferral percentage to zero. Some systems want you to type “0%” into the contribution field rather than checking a separate opt-out box, so confirm the change saved before you close the page.
Payroll needs a cycle or two to catch up. Expect one or two pay periods before the deduction disappears from your pay stub. Save the confirmation number or a screenshot when you submit the change. If money is still coming out after two full pay periods, contact your plan administrator with that confirmation in hand.
Stopping contributions is not the same thing as getting your money back. Setting your rate to 0% prevents future deductions but does nothing to return what’s already sitting in the account. For that, you need the permissible withdrawal.
Reclaim Contributions Within 90 Days
Federal regulation gives you a narrow window to pull back money that was automatically contributed. Under 26 CFR § 1.414(w)-1, you can request a permissible withdrawal of all default contributions if you act within 90 days of the date your first automatic contribution was deducted from your paycheck.1eCFR. 26 CFR 1.414(w)-1 – Permissible Withdrawals From Eligible Automatic Contribution Arrangements The clock starts on the date of that first paycheck deduction, not your hire date.
To make the request, contact your plan administrator. That is usually the financial institution running the 401(k), not your employer’s HR team, though HR can point you to the right contact. Tell them you want a permissible withdrawal under the plan’s eligible automatic contribution arrangement. They should have a form or process built for exactly this. The withdrawal covers all default contributions from the first deduction through the date your request takes effect.
The 90-day window is firm. No appeals, no extensions, no hardship exception. If day 91 arrives without a submitted request, the money stays put under the plan’s normal distribution rules.
What You Actually Get Back
The refund is not simply the sum of what was deducted. It is adjusted for investment gains or losses that occurred while the money sat in the account.1eCFR. 26 CFR 1.414(w)-1 – Permissible Withdrawals From Eligible Automatic Contribution Arrangements Market up during those weeks or months, you get back slightly more. Market down, slightly less. The plan administrator calculates the adjustment as of the date the distribution is processed.
Any employer matching contributions tied to the deferrals you are reclaiming get forfeited. Those match dollars return to the employer’s plan account automatically as part of the withdrawal.2Federal Register. Automatic Contribution Arrangements You cannot keep the match while pulling out your own money. Some plans also stop matching entirely for the rest of the plan year once you take a permissible withdrawal.
How the Refund Is Taxed
Permissible withdrawals get better tax treatment than a standard early distribution. The refund is not subject to the 10% early withdrawal penalty that normally hits 401(k) money taken before age 59½.3Internal Revenue Service. Instructions for Forms 1099-R and 5498 The plan administrator reports the distribution on Form 1099-R with distribution code 2, which tells the IRS a penalty exception applies.4Internal Revenue Service. Instructions for Forms 1099-R and 5498
If your default contributions were traditional pre-tax deferrals (the setup in most plans), the refund counts as ordinary taxable income for the year you receive it. You will owe federal and state income tax on it like regular wages. A permissible withdrawal is not an eligible rollover distribution, so you cannot move it to an IRA to defer the tax.
If the plan defaulted you into a designated Roth 401(k), the return of your own contributions is generally not taxed again because those dollars were already taxed on the way in. The 1099-R will show codes 2 and B to signal Roth treatment.4Internal Revenue Service. Instructions for Forms 1099-R and 5498 Any earnings on those Roth contributions during the brief time they were invested are taxable.
If the 90 Days Have Already Passed
Once the window closes, your contributions follow the same distribution rules as any other 401(k) balance. You generally cannot pull the money out until one of these events:5Internal Revenue Service. 401(k) Resource Guide – Plan Participants – General Distribution Rules
- You separate from the employer through resignation, termination, or layoff.
- You reach age 59½ and can take distributions without the 10% penalty.
- You become disabled, or the account passes to a beneficiary at death.
- The employer terminates the plan without replacing it.
- You qualify for a hardship distribution, if the plan allows them.
Hardship withdrawals are the only item on that list that does not require leaving your job or waiting years. To qualify, you have to show an immediate and heavy financial need. The IRS recognizes safe-harbor reasons including medical expenses, costs to prevent eviction or foreclosure, funeral expenses, and certain home repair costs.6Internal Revenue Service. Retirement Topics – Hardship Distributions Unlike permissible withdrawals, hardship distributions are subject to ordinary income tax and the 10% early withdrawal penalty if you are under 59½.7Internal Revenue Service. Hardships, Early Withdrawals and Loans They also cannot be rolled over.
If none of these fit, the money stays in the plan. You can still set your rate to 0% to stop new deductions, but the existing balance is effectively locked until a qualifying event. Some plans allow participant loans against the balance, though the feature is not universal.
If Deductions Keep Coming After You Opt Out
Payroll systems sometimes fail to update, or an opt-out request gets lost. If contributions keep appearing after you submitted a valid opt-out, document the timeline: when you submitted the request, the confirmation you received, and each pay period the deduction still ran. Flag the issue in writing to both HR and the plan administrator. The IRS requires employers to begin correct withholding by the last day of the month following the month you notified them of the problem.8Internal Revenue Service. 401(k) Plan Fix-It Guide – Excluding Eligible Employees
Contributions taken after a valid opt-out are a plan administration error, not a permissible default contribution. The employer is on the hook to fix it, which can include returning the excess deductions. If normal channels do not resolve the problem, the Department of Labor’s Employee Benefits Security Administration handles complaints about retirement plan administration.
Which Plans This Covers
The 90-day permissible withdrawal is a feature of eligible automatic contribution arrangements, and it applies whether your employer is auto-enrolling because the SECURE 2.0 Act requires it or because the plan chose to include automatic enrollment voluntarily. Government plans, church plans, employers in business fewer than three years, and employers with 10 or fewer employees are not required to auto-enroll under the federal mandate.9Office of the Law Revision Counsel. 26 USC 414A – Requirements Related to Automatic Enrollment If you work for one of those and money is still being deducted, it is a voluntary plan feature, and the opt-out and reclamation process work the same way as long as the plan is structured as an eligible automatic contribution arrangement. Check the plan’s summary description or ask the administrator to confirm before you rely on the 90-day rule.
