Reconstruct a late 401(k) deposit for the plan's correction review

For a suspected late employee-deferral deposit, collect the payroll withholding date and the actual plan receipt date. The IRS fix-it guide directs employers to compare deposits with the earliest date contributions could reasonably be separated from general assets, along with applicable plan requirements. A recurring monthly payment date is not sufficient evidence of timeliness.

Give the plan adviser the company's normal processing history. If contributions routinely reach the trust quickly, that history may matter to the review of a slower batch. Include ordinary successful runs as well as the exception, without presenting an outer regulatory deadline as a universal safe waiting period.

Separate employee deferrals from employer contributions in the file. Different obligations can apply. A single bank debit funding both categories should be supported by an allocation that shows which participant money was withheld and when it reached the plan.

Preserve the original deduction report, funding file, submission timestamp, bank movement and participant allocation result. Check rejected participant rows and incomplete batches. A successful bank debit can coexist with an allocation failure that left money outside the intended participant account.

Document each delay factually: when the error was discovered, who was notified, what correction was attempted and when funds became available. Include provider messages and internal approvals. Avoid rewriting the chronology to make a planned submission look like a completed deposit.

For a hypothetical $6,000 employee-deferral batch with $5,400 allocated and $600 rejected, the unresolved amount is $600. The adviser needs the affected participants and their respective dates. Treating the entire batch as deposited because most of it succeeded would hide the exception.

The IRS guidance identifies DOL's Voluntary Fiduciary Correction Program as a usual route for late-deposit problems and notes that IRS correction issues can also arise. Ask the adviser which requirements apply to this plan and event. Do not select a correction program solely from a software label.

Request the approved principal, earnings calculation, allocation method and any filing or notice requirements. Record who funds the correction and who confirms the trust received it. The employee's originally withheld amount and additional corrective earnings should remain separately traceable.

If the deposit is still outstanding, escalate it promptly to the authorized plan fiduciary and adviser. Preparing a complete historical packet should not become a reason to leave employee money unresolved. Preserve the information available and supplement it while the responsible parties address the funding.

Obtain evidence that the corrective amounts reached the proper participant accounts. Compare those allocations with the adviser-approved schedule and retain any reporting confirmation. An instruction to the recordkeeper is a pending action until the resulting account entries are verified.

Give finance the approved accounting treatment without circulating private participant balances unnecessarily. Record the company's correction cost separately from the original employee deferrals. The reconciliation should explain how withheld amounts were resolved and how additional employer-funded correction amounts were recorded.

Change the process that caused the delay, such as a missing file owner, rejected account mapping or manual funding approval. Test the next actual contribution batch through receipt and allocation. Keep the exception chronology with the plan records so future reviewers can distinguish this corrected event from later deposits.
