Missing 401(k) Paycheck Contributions: What to Check: key questions
A visual route through this article's first three topics. Read the sections below for details and exceptions.
Confirm Which Plan and Money Are Involved
This guide concerns employee payroll contributions to a private-sector retirement plan covered by ERISA, such as a covered 401(k).
Compare Paychecks With Plan Deposit Records
Make a pay-period list of amounts withheld and compare it with the plan's transaction history.
Do Not Treat Next Month as a Routine Deadline
The DOL fiduciary guidance describes the general rule: employee contributions must reach the plan as soon as they can reasonably be separated from the employer's general assets.
Confirm Which Plan and Money Are Involved
This guide concerns employee payroll contributions to a private-sector retirement plan covered by ERISA, such as a covered 401(k). Check the plan name, administrator and type of deduction before applying these rules. EBSA explains its coverage: federal, state and local government plans are outside ERISA, and church plans are generally outside Title I. Different rules can apply to those arrangements. A missing employee deduction, an expected employer match and a change in investment value are separate questions.
Compare Paychecks With Plan Deposit Records
Make a pay-period list of amounts withheld and compare it with the plan's transaction history. Ask when each amount reached the plan, not just when it appeared on your screen. The Labor Department's contribution rule distinguishes deposit into a plan account from later allocation to particular participants or investments. A posting mismatch deserves an explanation; a screen display alone does not establish that an employer kept the money. Check whether the records refer to the same pay dates and contribution category.
Do Not Treat Next Month as a Routine Deadline
The DOL fiduciary guidance describes the general rule: employee contributions must reach the plan as soon as they can reasonably be separated from the employer's general assets. The 15th business day of the following month is an outer limit, not routine permission to wait that long. An employer capable of separating the money earlier ordinarily must do so, subject to an applicable safe harbor. Do not postpone raising a discrepancy merely because the next month has not ended.
Understand the Limited Small-Plan Safe Harbor
The final regulation provides a seven-business-day safe harbor for a plan with fewer than 100 participants at the beginning of the plan year. For payroll withholding, the period runs after the day the amount otherwise would have been paid in cash. This is a plan-participant test, not simply the company's employee headcount. It is not a universal seven-day rule for every retirement arrangement. Outside the safe harbor, timeliness must be evaluated under the applicable general rule and facts.
Separate Employer Matching Contributions
The IRS contribution guidance explains that employer matching and other employer contributions follow different timing rules from employee deferrals. Review the plan terms for the amount and timing of a promised match; do not apply an employee-withholding deadline to it without checking. Also distinguish the deposit of money from vesting, which concerns your right to retain a benefit. A statement showing an unvested employer contribution is not the same thing as a missing deduction from your wages.
Ask the Plan Administrator for an Explanation
The DOL retirement-plan guide explains how the summary plan description identifies plan rules and how to seek information from the administrator. Send a focused written question listing the pay dates and amounts that do not reconcile. Ask for the relevant deposit or allocation records, an explanation of any correction, and the procedure for disputing the result. Keep the response and plan documents. If payroll and the recordkeeper give different answers, preserve both accounts rather than assuming either one resolves the discrepancy.
Keep Your Evidence Private and Organized
Retain pay statements, contribution elections, benefit statements, relevant transaction records and your written questions. Keep originals intact and note when you received each response. Use lawful access to your own records; do not enter employer or coworker accounts to investigate. Before sharing documents, redact unrelated transactions and account identifiers, and use the intended secure submission channel. Never provide an online-account password. A simple dated comparison is more useful than an unsupported accusation or an estimate that mixes withheld amounts with market losses.
Seek Help Without Missing Plan Procedures
You can request assistance from an EBSA Benefits Advisor about a covered retirement-plan problem. EBSA describes informal resolution and possible further review, but does not guarantee that every complaint produces an investigation. Its assistance does not replace timely plan document requests, benefit claims or appeals. Review the actual notices and ask which procedures and deadlines apply rather than assuming an agency inquiry pauses them. Seek qualified advice promptly if the discrepancy remains unexplained or a response deadline is approaching.
A Correction Is Not a Guaranteed Cash Payment
IRS guidance on late contributions describes corrections that may include missed deferrals and lost earnings paid into the plan trust. That is different from a promise of a cash payment directly to the employee. The applicable remedy depends on the plan, facts and legal requirements. Ask how any proposed correction addresses each missing amount and retain the confirmation. This information does not establish wrongdoing in a particular case; legal-service availability depends on the state, matter and eligibility.
