If a 401(k) deduction appears on a pay stub but not in the plan account, compare every pay date, employee deferral, employer contribution, and posting date in one ledger. Ask payroll and the plan administrator for the transmission date and correction status. Employee deductions must be sent to the plan promptly, and a correction can require both the missing amount and lost earnings.
Workers describe five to nine consecutive paychecks with deductions that never reached the plan. The useful first move is a paycheck-by-paycheck audit that separates employee money from employer match and normal posting delay.
Start here: a practical action plan
- Export pay stubs and plan transactions.
- Match deductions to deposits.
- Send the exact discrepancy in writing.
- Verify principal and lost earnings.
- Combining employee and employer timing.
- Accepting a rolling delay without batch proof.
- Counting missing money as invested.
Reconcile deductions and deposits separately
Download pay stubs and plan transaction history for the same period. For each paycheck, record the pay date, employee pre-tax or Roth deferral, loan repayment if any, employer match, and plan posting date. Employer contributions can follow different timing rules, so do not combine them with employee deductions.
Allow for a documented processing lag, but do not let a rolling delay hide a missing batch. Ask payroll when the employee money left payroll, the confirmation or batch number, and which plan administrator received it. Ask the plan recordkeeper whether the money is pending, rejected, or absent.
Worked example: prove the missing principal
Example: three pay stubs each show a $420 employee deferral. The plan shows only the first deposit. Missing employee principal is 2 x $420 = $840. A promised $84 match is tracked separately because its timing and vesting terms may differ.
The $840 calculation establishes principal, not the final correction. IRS correction guidance says late deposits may require lost earnings. The employer or plan must calculate that amount under the applicable correction process. Do not invent an investment return and call it final.
| Hypothetical deposit audit | Pay stubs | Plan account | Difference |
|---|---|---|---|
| Paycheck 1 | $420 | $420 | $0 |
| Paycheck 2 | $420 | $0 | $420 |
| Paycheck 3 | $420 | $0 | $420 |
| Missing employee principal | $1,260 | $420 | $840 |
Escalate with dates instead of estimates
Send a concise written timeline to payroll, human resources, and the plan administrator. Include pay dates, exact deductions, plan postings, missing total, supporting files, and the date you first reported the issue. Request a written correction date and lost-earnings calculation.
If the response stalls or the employer cannot account for employee deductions, contact a U.S. Department of Labor Employee Benefits Security Administration benefits adviser through Ask EBSA. Provide copies with sensitive account numbers redacted where appropriate, and keep originals.
Verify principal and lost earnings after correction
When a correction posts, match each entry to the ledger. Confirm whether the transaction label represents employee principal, employer money, and lost earnings. Save the corrected statement and the employer explanation.
Keep contributing only if it still fits the household plan and you are comfortable monitoring the issue. A missing deposit is not available cash, and it should not be counted twice as both retirement savings and spendable income.
- Export pay stubs and plan transactions.
- Match every deduction to a dated deposit.
- Send the exact discrepancy to payroll and the plan.
- Verify principal and lost earnings when corrected.
Frequently asked questions
How long should a 401(k) deposit take?
The legal timing depends on when the employer can reasonably separate employee money from general assets and on plan circumstances. A familiar payroll lag is not proof that every delay is acceptable.
Does a missing employer match follow the same rule?
Not necessarily. Employee deductions and employer contributions can have different deadlines, formulas, and vesting terms, so audit them separately.
What are lost earnings?
They are an amount intended to restore investment opportunity lost because employee money reached the plan late. The responsible party should calculate them under the correction method.
Should I contact the recordkeeper or payroll first?
Contact both. Payroll can identify the transmission batch, while the recordkeeper can confirm whether it received, rejected, or posted the money.
When should I contact the Department of Labor?
Ask EBSA when plan fiduciaries cannot account for employee deductions, correction stalls, or you need help understanding participant rights.
Can I count the missing contribution in my net worth?
Track it as a documented retirement receivable until it actually posts. Do not treat it as available cash or confirmed invested balance.
