What is a 401(k) liability?

Withheld and matched retirement contributions owed to the plan provider until the plan is funded.

Definition

A 401(k) liability is the amount of withheld and matched retirement contributions still owed to the plan provider. On the books, this is a current liability that holds both the employee deferral and the employer match until the plan is funded.

The withheld slice is not extra expense. It was part of gross wages; it simply did not go out in the paycheck.

The employer match is an expense. That cost hits the Income Statement when the wages are earned, and the unpaid match sits here until you remit.

Cash-basis books may still carry this line. Money withheld from a paycheck is held for the plan, even if you record wages only when cash moves.

Where it shows up

Balance sheet: Located in the current liabilities section.

P&L: Related to the employer match sitting in benefits expense.

Cash flow: Decreases in this account, reported cash from operating activities decreases.

When you look at your Balance Sheet, this line sits in current liabilities, near payroll tax liability and accrued payroll. When the balance is high, more deferrals and match are waiting for the next funding; when it is low, you have just remitted.

The Income Statement does not list the withheld slice as its own cost. Related P&L cost is the employer match, which is recorded in employee benefits expense when the wages are earned.

On the Statement of Cash Flows, funding the plan is the cash event. Cash from operating activities falls when you remit, and this liability falls with it.

A payroll register shows each person's deferral, the employer match, and take-home pay for a run. This account is the unpaid retirement total those registers have not yet sent to the provider.

How it works

A typical path starts with a payroll run. Gross wages are recorded, the employee elects a deferral, and that slice is withheld from take-home pay.

Those withholdings credit this liability. They are still the employee's money, parked here until the plan receives them.

The employer match is recorded at the same time, or at cutoff if wages were accrued. The match debits employee benefits expense and credits this same liability.

What usually sits in this liability after a run:

  • Employee elective deferrals withheld from take-home pay
  • The employer match still owed to the plan
  • Any catch-up contributions that have not yet been remitted

Net pay is what the employee actually receives. Gross wages minus tax, benefits, and this deferral equals take-home pay; the deferred dollars did not disappear, they moved into this account.

Accrued liabilities may hold other unpaid extras, such as a health premium. Unpaid retirement money belongs here, not in a generic accrual, once the plan is the payee.

When the funding date arrives, you send the combined balance to the provider. The payment debits this liability and credits cash.

After a clean remittance, the slice for that run should be zero, or reduced to any amount not yet due. A leftover that does not match the next plan statement is a reconciliation problem.

Tie the ledger to the payroll register and to the plan reports. Account reconciliation here means the liability equals deferrals and match that have not been sent yet.

Example

Cedar Code is a consulting firm that runs payroll every other Friday. This run's gross wages are $8,000.

Employees defer into the plan, and the firm matches $240. Take-home pay is lower by the deferral; the $240 is the firm's own extra.

The firm records the match:

Debit: Employee benefits expense $240

Credit: 401(k) liability $240

Benefits expense hits the P&L by $240, and this liability goes up by $240. Withheld deferrals reach the same liability through the payroll journal entry, which reduced take-home pay rather than adding a second expense.

The Balance Sheet now shows the unpaid deferrals plus this $240 match until the plan is funded. Cash for the plan has not moved yet; only the paychecks have.

A few days later Cedar Code funds the combined balance. This liability for that run falls back to zero, and cash falls by the same remittance.

The Income Statement does not take another match cost at funding. Paying only settles the owe.

Common mix-ups

A 401(k) liability is not employee benefits expense. The expense is the match cost on the Income Statement; this line is the unpaid deferral and match on the Balance Sheet.

A 401(k) liability is not payroll tax liability. Tax withheld and the employer tax sit in the tax payable lines; retirement money sits here.

A 401(k) liability is not take-home pay. The deferral reduced what the employee received; this account holds that slice, plus the match, until the plan is funded.
