Retirement Funding Reached the Account, but Was It Posted to the Correct Year?

A completed bank transfer does not prove correct plan posting

An owner sees money leave the company account and assumes retirement funding is finished. The next step is to verify the participant, contribution type, plan year, and amount posted by the recordkeeper. IRS retirement guidance distinguishes contribution categories and timing requirements. The approved calculation and actual posting should agree; a payment confirmation alone may not contain enough information to establish that agreement.

Prepare funding instructions before initiating the transfer. Identify the plan, participant, employer, intended contribution category, applicable year, calculation reference, and approved amount. Ask the administrator to confirm the terminology used by the recordkeeper. A label such as retirement contribution may be too broad when the plan distinguishes employee deferrals, employer funding, catch-up amounts where applicable, and other categories.

A hypothetical year-end mismatch

Assume the administrator approves a $40,000 employer contribution for the intended plan year. The company transfers $40,000 in March and the recordkeeper posts it as current-year employee deferrals because the payment form used the wrong category. The dollar amount arriving in the account does not resolve the mismatch. The company should contact the administrator and recordkeeper with the approval, funding instruction, and posting evidence before relying on the transaction for tax reporting.

The appropriate correction depends on the plan, timing, and actual records. Do not withdraw and redeposit the money informally or assume a bookkeeping change corrects the plan account. Ask for the applicable procedure, responsible party, required documentation, and final confirmation. The owner’s tax preparer should know the issue is unresolved until the correct treatment is supported.

Suppose the company separately processes employee deferrals through payroll. Match those amounts to payroll registers and recordkeeper deposits by pay period. Employer funding and employee withholding should not be combined into one unexplained annual balance. If a difference exists, identify whether it reflects a posting error, missing deposit, timing difference, or incorrect calculation before selecting a correction.

Build a contribution control ledger

Use one line per funding event with approved amount, actual payment date, bank reference, participant, intended year and type, recordkeeper posting, and review status. Attach the administrator’s calculation and final account evidence. A status of initiated should remain separate from received and verified. This distinction prevents the owner from assuming an attempted transfer succeeded when the bank or recordkeeper rejected it.

For a payment spanning several participants or categories, retain the allocation file used to instruct the recordkeeper. Reconcile the total to the bank debit and each participant’s posting. If the allocation file changes, preserve the version history and who approved the final one. The owner should not need to reconstruct the intended split from a general-ledger entry months later.

Close the loop with the preparer

Give the tax preparer the final verified contribution schedule, including actual dates and any corrections. Identify amounts still pending and explain which year and type the administrator supports. Do not use an earlier contribution illustration as evidence that funding occurred. The illustration shows a plan; the account records and confirmations show implementation.

Review the process after the return is prepared. If recurring terminology causes errors, agree a standard instruction form with the provider and add a second review before large owner funding. This guide does not determine the correct contribution year or applicable deadline for a particular plan. It gives the company a reconciliation process so an otherwise valid retirement strategy is not undermined by a payment posted to the wrong category, person, or year.

Keep the evidence accessible after a provider change. Historical posting records may be needed to explain a later correction or limit calculation. Download the final statements and correspondence rather than assume the old portal will remain available indefinitely after the account is moved.

For a rejected transfer, document the reason and the date funds returned to the company. A second attempt should reference the corrected instruction and confirm that the first payment was not also posted. This is especially useful near a deadline, when several people may try to solve the same failed funding event and inadvertently create a duplicate deposit.
