In almost all cases, your employer cannot take money out of your 401(k). Federal law requires plan assets to be held in a trust that exists solely for you and other participants, and your employer has no ownership claim on that money.1Office of the Law Revision Counsel. 29 USC 1103 – Establishment of Trust A handful of narrow exceptions do let funds leave your account: unvested employer contributions can be forfeited when you leave, genuine payroll or contribution-limit errors can be corrected, an unpaid 401(k) loan can be offset after you separate, and a court can order transfers for divorce, tax debts, restitution, or fiduciary misconduct. Outside those situations, an employer that pulls money out is breaking federal law.
The General Rule: Your Employer Cannot Touch It
ERISA’s anti-alienation rule says benefits in a qualified retirement plan cannot be assigned or alienated.2Office of the Law Revision Counsel. 29 USC 1056 – Form and Payment of Benefits Your employer cannot pull money from your account to recover a broken laptop, offset a missed sales target, settle a business debt, or punish you. Your own paycheck contributions are 100% yours from day one, and the vested portion of any employer contributions is yours too.
The protection holds even if the company itself collapses. Because plan assets sit in a trust legally separate from the company’s general assets, your employer’s creditors cannot reach your 401(k) in a bankruptcy.3U.S. Department of Labor. FAQs About Retirement Plans and ERISA The Supreme Court has confirmed that ERISA’s anti-alienation clause keeps a participant’s plan interest out of the bankruptcy estate.4Legal Information Institute. Patterson v. Shumate, 504 U.S. 753 (1992)
So when money does legitimately leave a participant’s account, it happens under one of the specific exceptions below.
Forfeiture of Unvested Employer Contributions
This is the most common reason people see their 401(k) balance drop after leaving a job. Employer matches and profit-sharing deposits vest on a schedule set by the plan. Federal rules allow two main structures:5Internal Revenue Service. Retirement Topics – Vesting
- Cliff vesting: you own 0% of employer contributions until three years of service, then 100% at once.
- Graded vesting: ownership steps up each year, typically starting at 20% after year two and reaching 100% after year six.
If you leave before you’re fully vested, the unvested portion is forfeited. Those dollars do not go to your employer’s bank account. They stay inside the plan trust and are used to pay plan administrative costs or reallocated as contributions to other participants.
Two situations can reverse a forfeiture. If you’re rehired before five consecutive one-year breaks in service and earn a new year of service, the plan generally must restore what it forfeited.6Internal Revenue Service. Improper Forfeiture by Defined Benefit Plans And if the IRS treats a large layoff (generally more than 20% of participants in a year) as a partial plan termination, every affected employee becomes 100% vested immediately, regardless of where they stood on the schedule.7Internal Revenue Service. Retirement Plan FAQs Regarding Partial Plan Termination If you were part of a significant layoff and your employer forfeited unvested contributions, you may have a claim to get those funds back.
Correcting Payroll Errors and Excess Contributions
Your employer can pull back money that was deposited by mistake. This isn’t a seizure; the excess was never legally supposed to be in the account in the first place.
A payroll mistake is the classic example. If someone keys $5,000 into the payroll system instead of $500, the employer can recover the overpayment, but must act within one year of the mistaken contribution. Any investment gain or loss on the excess while it sat in the plan has to be accounted for in the correction.
The other trigger is exceeding the IRS annual contribution limits. When more goes in than the law allows, the excess must be distributed back to you along with any earnings on it. A plan that fails to fix excess contributions by the required deadline faces a 10% excise tax on the excess amount.8Office of the Law Revision Counsel. 26 USC 4979 – Tax on Certain Excess Contributions The earnings portion of a corrective distribution is generally taxable income the year you receive it, so a correction can leave you with a small tax bill even though it isn’t a penalty.
Loan Offsets After You Leave
If you borrowed from your 401(k) and left the job before paying it back, the unpaid balance can be offset against your account. This surprises a lot of people because it looks like the employer took money, but the law treats it as a distribution to you, not a seizure by the employer.9Internal Revenue Service. Plan Loan Offsets
Most plan documents require immediate repayment when you separate, or treat the loan as defaulted at that point. The offset amount gets reported on a Form 1099-R as a distribution. You owe income tax on it, plus the 10% early withdrawal penalty if you’re under 59½. You can avoid both by rolling the offset amount into an IRA or another employer plan within 60 days, or by your tax-filing deadline for the year if the offset resulted from plan termination or severance from employment.
Divorce and Qualified Domestic Relations Orders
Divorce is one of the most common ways 401(k) money legitimately leaves your account and goes to someone else. A court can issue a Qualified Domestic Relations Order (QDRO) directing the plan to pay part of your benefits to a spouse, former spouse, child, or other dependent.10U.S. Department of Labor. QDROs Chapter 1 – Qualified Domestic Relations Orders: An Overview This is a statutory exception written into the same anti-alienation rule that otherwise blocks transfers.2Office of the Law Revision Counsel. 29 USC 1056 – Form and Payment of Benefits
To qualify, the order has to name the participant and the alternate payee, identify each plan it applies to, spell out the dollar amount or percentage, and state the number of payments or the time period. It cannot require the plan to pay a benefit type the plan doesn’t offer, or to pay more than the plan’s total benefit.
Once the plan administrator receives a domestic relations order, it must notify both parties, determine within a reasonable time whether the order qualifies, and set aside the amounts that would be payable, holding them for up to 18 months so nothing gets paid out prematurely.11U.S. Department of Labor. QDROs – Determining Qualified Status and Paying Benefits FAQs
One benefit for the alternate payee: distributions received under a QDRO from a 401(k) are exempt from the 10% early withdrawal penalty, even if the alternate payee is under 59½.12Office of the Law Revision Counsel. 26 USC 72 – Annuities; Certain Proceeds of Endowment and Life Insurance Contracts The money is still ordinary income tax unless rolled over into the alternate payee’s own IRA or retirement plan.
IRS Levies, Restitution, and Fiduciary Breaches
Three government-driven exceptions can reach your 401(k). None of them let your employer take the money for its own use; each requires a specific legal action.
The IRS can levy retirement assets to collect unpaid federal taxes. The tax code gives the IRS the power to reach “all property and rights to property” of a taxpayer who ignores a notice and demand, and that authority overrides ERISA’s anti-alienation rule.13Office of the Law Revision Counsel. 26 USC 6331 – Levy and Distraint As a matter of internal policy the IRS generally doesn’t levy on retirement accounts unless the taxpayer has engaged in “flagrant conduct,” meaning a pattern of deliberate noncompliance rather than an honest mistake. The agency can also proceed if you agree to a voluntary levy as part of a collection arrangement.
The Mandatory Victims Restitution Act allows the federal government to enforce a criminal restitution judgment against “all property or rights to property” of the defendant, notwithstanding any other federal law.14Office of the Law Revision Counsel. 18 USC 3613 – Civil Remedies for Satisfaction of an Unpaid Fine Courts have read this to override ERISA, meaning a defendant’s 401(k) can be garnished to pay victims under a federal court order.
Finally, if a participant also served as a plan fiduciary and violated fiduciary duty rules (for example, by embezzling plan assets), the plan can offset that person’s benefits to repay the loss. The offset is only allowed when a court judgment, consent decree, or settlement with the Department of Labor or the Pension Benefit Guaranty Corporation specifically authorizes it.15Office of the Law Revision Counsel. 29 USC 1056 – Form and Payment of Benefits
What to Do if You Think Your Employer Took Money Improperly
If money left your account and none of the exceptions above fits, treat it as a benefit dispute and move through the process ERISA lays out.
Start With the Plan’s Internal Claim Process
Every ERISA-covered plan must have a written claims procedure. You have at least 60 days after receiving notice of an adverse decision to file an appeal with the plan’s named fiduciary. You can submit written arguments and request free copies of all documents relevant to your claim. The administrator has 60 days to respond, with one possible 60-day extension if special circumstances require it.16eCFR. 29 CFR 2560.503-1 – Claims Procedure
File a Complaint With EBSA
If the internal appeal doesn’t resolve things, file a complaint with the Department of Labor’s Employee Benefits Security Administration. Benefit Advisors review complaints and can refer cases to an enforcement unit. If a formal investigation opens, the regional office must update you quarterly.17U.S. Department of Labor. Enforcement Manual – Complaints EBSA cannot guarantee your identity will remain confidential in a benefit dispute.
Sue in Federal Court
ERISA lets you sue in federal court to recover benefits, enforce your plan rights, or stop an ongoing violation. If you prevail, the court has discretion to award reasonable attorney’s fees and costs.18Office of the Law Revision Counsel. 29 USC 1132 – Civil Enforcement You generally must complete the plan’s internal claims procedure first, so don’t skip that step even if you expect to end up in court.
The consequences for an employer that removes money outside the legal exceptions are serious. EBSA can pursue restoration of losses and civil penalties.19U.S. Department of Labor. ERISA Enforcement Theft or embezzlement from an employee benefit plan is a federal crime under 18 U.S.C. § 664, and people convicted can be barred from any plan-related position for up to 13 years. Unauthorized withdrawals can also cost the plan its tax-qualified status, which triggers immediate taxation of vested employer contributions and loss of the employer’s deduction.20Internal Revenue Service. Tax Consequences of Plan Disqualification Those stakes are why the law’s answer to your question is a firm no everywhere the narrow exceptions don’t reach.
