How to Record 401k Forfeitures: Journal Entries, Deadlines, and Fixes

Recording a 401(k) forfeiture takes two sets of journal entries. The first captures the forfeiture event itself: debit Plan Liability and credit a Forfeiture Reserve for the unvested amount the departing participant leaves behind. The second happens when the plan actually spends those dollars, which must occur within 12 months after the close of the plan year in which the forfeiture arose. At that point you debit the Forfeiture Reserve and credit whichever account matches the permitted use — employer contribution expense, cash or accounts payable for a plan bill, or a participant allocation account. The funds stay inside the plan trust the entire time and never revert to the company’s general treasury.

Step 1: Recording the Forfeiture When It Occurs

Before touching the ledger, confirm the date the forfeiture is actually triggered. Most 401(k) plans forfeit the unvested balance immediately when a participant separates from service, provided the plan document includes a restoration provision covering rehires within five consecutive one-year breaks in service.¹ Plans with a cash-out feature typically trigger the forfeiture when the vested balance is distributed. A smaller number of plans wait until the participant has actually accumulated five consecutive one-year breaks in service.² The plan document controls, so check the vesting and forfeiture provisions before you post anything. Recording the entry in the wrong year is itself an operational error.

The recordkeeper or third-party administrator certifies the exact dollar amount. That certification is your source document. The entry has two lines:

Debit Plan Liability for the forfeited amount, extinguishing the obligation to the departed participant.
Credit Forfeiture Reserve for the same amount, parking the funds in an unallocated holding account inside the plan trust.

If a participant separates with a $12,000 unvested balance, the entry is Debit Plan Liability $12,000, Credit Forfeiture Reserve $12,000. The Forfeiture Reserve sits on the plan’s financial statements as an unallocated balance within net assets.

Partial Vesting

Only the unvested portion is forfeited. Total employer contribution balance minus the vested portion equals the forfeiture. A participant who is 40% vested in a $10,000 employer contribution balance keeps or takes $4,000; the remaining $6,000 is what hits the Forfeiture Reserve.² When several participants forfeit in the same period, check each individual’s vesting percentage against the recordkeeper’s certification before posting a combined entry.

Timing

Post the entry shortly after the vested balance is distributed, or as part of a year-end true-up cycle if that’s how the plan operates. Either way, the entry needs to land in the same plan year the forfeiture event occurred, because that year starts the 12-month application clock.

Step 2: Recording the Application of Forfeiture Funds

The second set of entries draws down the reserve as the plan applies it. IRS proposed regulations applicable to plan years beginning on or after January 1, 2024 confirm three permitted uses for defined contribution plans: reducing employer contributions, paying reasonable plan expenses, and allocating to remaining participants.³ The plan document sets the priority, and the entry differs for each use.

Reducing Employer Contributions

This is where most forfeiture dollars go, because it delivers a direct cash benefit to the sponsor. If the plan requires a $50,000 employer match and holds $8,000 in forfeitures, the company funds only $42,000 in cash and the $8,000 comes from the reserve.

Debit Forfeiture Reserve for $8,000. The credit side depends on whether the employer has already accrued the contribution expense. If the expense is accrued, credit Employer Contribution Expense, which nets down the recognized cost. If the liability is on the books but not yet funded, credit Accrued Employer Contribution Liability instead.

Back the reduction with a corporate resolution or board authorization, and keep a subsidiary ledger that traces the forfeiture amount from the reserve into the contribution calculation. External auditors reviewing the corporate financials will look for that trail.

Paying Plan Administrative Expenses

Recordkeeping fees, third-party administrator compensation, legal costs, and audit fees can all be paid from the reserve. Debit Forfeiture Reserve and credit Cash if the bill has already been paid, or credit Accounts Payable if it is accrued but unpaid. A $2,000 recordkeeping fee paid from forfeitures is Debit Forfeiture Reserve $2,000, Credit Cash $2,000. Keep the invoice with the entry — auditors look for a clean tie between the specific cost and the specific drawdown.

Allocating to Remaining Participants

When the plan document directs forfeitures to be allocated as additional employer contributions, debit Forfeiture Reserve and credit the individual participant allocation accounts, or a general Participant Accounts Payable at the plan level. The allocation follows whatever formula the plan document specifies, often pro rata based on compensation or account balances, and it must satisfy nondiscrimination requirements.

Because these allocations are treated as employer contributions, they count toward each participant’s annual addition limit under Section 415(c), which is $72,000 for 2026.⁴⁵ Verify before you post that no participant’s combined annual additions will exceed that limit. An allocation that pushes someone over the cap creates a separate compliance problem.

Reversing the Entry When a Rehired Participant Requires Restoration

If a former employee is rehired before accumulating five consecutive one-year breaks in service, and the plan uses a cash-out and restoration provision, the employer may have to restore the previously forfeited amount once the participant repays any distribution received.¹

The restoration reverses the original entry. Debit Forfeiture Reserve to reduce the unallocated balance and credit the participant’s Plan Liability to reinstate the obligation. If the reserve doesn’t hold enough to cover the restoration — because the plan already spent it down — the employer funds the difference from corporate cash: Debit Cash or Employer Contribution Expense, Credit Plan Liability.

That risk is why some practitioners suggest not spending the reserve down aggressively early in the plan year. Applying a large forfeiture to reduce contributions in January and then rehiring the same participant in April forces the company to come up with the money from somewhere. Keeping a cushion, or timing the application closer to the deadline, avoids that whipsaw.

The 12-Month Deadline and Form 5500 Reporting

Under the IRS proposed regulations, forfeitures in a defined contribution plan must be used no later than 12 months after the close of the plan year in which they were incurred.³ For a calendar-year plan, forfeitures that arose during 2026 must be applied by December 31, 2027. If the plan document sets a shorter deadline, that shorter one governs.

The reserve balance and its activity for the year show up on Form 5500. Large plans report on Schedule H; small plans use Schedule I.⁶ Payments made directly from the forfeiture account are reportable as direct compensation on those schedules. Reconcile the reserve to the general ledger quarterly so there are no surprises when the Form 5500 preparer pulls the numbers.

Fixing Mistakes

Missing the 12-month deadline, applying forfeitures for a purpose the plan document doesn’t authorize, or miscalculating the forfeiture amount are all operational failures. The IRS Employee Plans Compliance Resolution System offers three correction paths: self-correction for eligible failures found before audit, a voluntary correction program that requires a fee and IRS approval, and an audit closing agreement when the failure surfaces during an examination.⁷ Self-correction is the least disruptive route, but it is only available for certain failures and only if the plan has established compliance practices in place.⁸

Prevention is simpler than correction. Record each forfeiture promptly against the recordkeeper’s certification, maintain a subsidiary ledger for every debit and credit to the reserve, tie each application to a plan document review and, where relevant, a board authorization, and apply the balance well before the deadline.
