Defined Contribution vs Defined Benefit Plans under IAS 19

Updated 11 October 2026

Under IAS 19, a post-employment plan is defined contribution if the employer's obligation is limited to the contributions it agrees to pay and it bears no actuarial or investment risk. Otherwise it is defined benefit. For a DC plan you expense the contribution for the period and recognise a liability only for unpaid amounts, or an asset for prepayments.

Understand Defined Contribution vs Defined Benefit Plans

A post-employment benefit plan is an arrangement where an entity provides benefits to employees after they retire. The key question is: who carries the risk that the money will not be enough?

In a defined contribution (DC) plan, the employer pays fixed contributions into a separate fund, usually a legal entity. The employer has no legal or constructive obligation to pay more if the fund is short. The employee bears the actuarial risk (benefits lower than expected) and the investment risk (assets perform badly). So the accounting is simple.

In a defined benefit (DB) plan, the employer promises a specific benefit, often based on final salary and years of service. If the assets are not enough, the employer must make up the gap. The employer carries the actuarial and investment risk. That needs actuarial estimates, discounting and a net liability or asset in the statement of financial position. Those measurement rules are covered in the DB topics.

Classification depends on the substance of the plan's terms, not its name. A plan called a 'contribution' plan is a DB plan if the employer guarantees a return or has a constructive obligation to top up the fund. A constructive obligation can arise from past practice, such as the entity regularly topping up the fund to protect benefits.

Special cases are tested. Multi-employer plans pool assets from several unrelated employers. Classify each as DC or DB by its terms. If it is DB but there is not enough information to account for your share, you account for it as DC and give extra disclosures. State plans must be accounted for in the same way as multi-employer plans. They are treated as DC if the entity's obligation is limited to the contributions due in the period, and otherwise as DB. For most state plans the obligation is limited to the contributions due in the period, so they are DC. Insured benefits are DC if the entity has no legal or constructive obligation to pay further amounts if the insurer fails to pay all benefits.

Key rules to remember

DC plan expense: Expense = contribution payable for the period; Recognised in profit or loss, unless another standard allows it to be included in the cost of an asset, such as inventory or self-constructed property, plant and equipment.
DC liability or asset at year end: Liability = contribution due − contribution paid (if positive); Asset (prepayment) = contribution paid − contribution due (if positive); Prepayment is recognised as an asset only to the extent it will reduce future payments or give a cash refund.
DC classification test: DC if the entity pays fixed contributions into a separate entity AND has no legal or constructive obligation to pay further contributions; Actuarial and investment risk then fall on the employee. Any guarantee or constructive obligation to cover a shortfall makes it DB.
Discounting of DC contributions: Discount only if contributions are not expected to be settled wholly within 12 months after the end of the period in which the service was rendered; Use the rate based on high-quality corporate bonds, as for DB obligations.
Multi-employer DB plan without enough information: Account for the plan as if it were DC and disclose that fact; Applies where sufficient information to apply DB accounting to your share is not available.

How to solve Defined Contribution vs Defined Benefit Plans questions

Use this method for any question on classification or DC accounting.

1Read the plan terms. Find who pays, who guarantees the benefit, and who bears investment and actuarial risk.
2Look for hidden obligations: guaranteed returns, top-up promises, or a past practice of covering shortfalls (constructive obligation).
3Classify the plan as DC or DB. If it is a multi-employer, state or insured plan, apply the specific rule for that type.
4For a DC plan, calculate the contribution earned by employees for service in the period (for example, a percentage of salary).
5Compare the amount due with the amount paid. Record any difference as an accrued liability or a prepayment.
6Post the expense to profit or loss, or capitalise it if employees' costs are part of an asset under another standard.
7Check discounting: only needed if payment falls beyond 12 months after the period end.
8State your conclusion in a sentence and link it to the scenario facts, as the exam awards marks for application.

Quickest way: Risk test then simple accrual

When to use it: Use when time is short and the question gives plan terms plus contribution figures.

Ask: if the fund runs short, does the employer have to pay more? If yes, DB. If no, DC.
For a DC plan, the expense is the contribution due for the year. Do not remeasure anything.
Liability = due − paid. If paid is higher, show a prepayment.
Write one line each for classification reason, expense, and statement of financial position effect.

Common mistakes in Defined Contribution vs Defined Benefit Plans

Classifying a plan as DC because it is called a 'contribution' scheme.
Students trust the name and skip the plan terms.
Fix: Classify by substance. Look for guarantees, minimum returns or a pattern of top-ups that create a constructive obligation.
Recognising a net deficit or surplus for a DC plan.
Students carry DB accounting across to DC plans.
Fix: For DC, only the expense and any unpaid or prepaid contribution appear. No actuarial gains or losses, no remeasurements in OCI.
Expensing the cash paid instead of the contribution earned for the period.
Cash timing and accruals get mixed up.
Fix: Expense the contribution payable for service in the year. Adjust the liability or prepayment for any difference from cash paid.
Treating a multi-employer DB plan as DC in all cases.
Students remember the exception but forget its condition.
Fix: Use DC treatment only when the plan is DB in nature and there is not enough information to account for your share as DB. Then disclose that.
Ignoring the constructive obligation when a scenario says the company 'always covers shortfalls'.
Students focus on the legal wording only.
Fix: IAS 19 includes constructive obligations from informal practice. Past top-ups can turn a DC plan into a DB plan.
Writing generic definitions without using the scenario.
Students recall theory but do not apply it.
Fix: Quote the plan facts, such as guaranteed return or fixed percentage, and state the conclusion they lead to.

Worked examples

Example 1

Zeta Co pays 8% of gross salary into an independently managed pension fund for its employees. The rules state that Zeta has no obligation to pay more if the fund is insufficient. Salaries for the year were $12,500,000. Zeta paid $900,000 during the year and the remainder was paid after year end. Explain the classification and show the amounts in the financial statements.

Show the solution

Classification: Zeta's obligation is limited to the 8% contribution. It has no legal or constructive obligation to cover a shortfall. Employees bear the investment and actuarial risk. The plan is defined contribution.
Expense: 8% × $12,500,000 = $1,000,000, recognised in profit or loss for the year.
Liability: contribution due $1,000,000 − paid $900,000 = $100,000 accrued liability.
No actuarial valuation, no net asset or liability for the fund, and no OCI remeasurement is needed.

Answer: The plan is defined contribution. Profit or loss expense is $1,000,000 and an accrued liability of $100,000 is shown at year end.

Example 2

Beta Co has a pension plan in which it pays 6% of salary into a fund. Employees receive the fund value at retirement, but the plan terms guarantee a minimum annual return of 4%. Beta says the plan is defined contribution because contributions are fixed. Advise the board on classification and the effect on the financial statements.

Show the solution

Test who bears investment risk. Beta guarantees a minimum return of 4%, so if the fund earns less, Beta must pay the shortfall.
The employer's obligation is therefore not limited to the fixed 6% contribution. Actuarial and investment risk fall at least partly on Beta.
Conclusion: the plan is a defined benefit plan despite the fixed contribution rate.
Effect: Beta must measure the obligation using the projected unit credit method, deduct the fair value of plan assets, and recognise the net liability or asset. Service cost and net interest go to profit or loss, and remeasurements go to OCI.
Advice: the board's view is not supported. Accounting as DC would understate the liability if the guarantee is likely to bite.

Answer: The guaranteed minimum return makes the plan defined benefit. Beta must recognise a net defined benefit liability or asset, not just the contribution expense.

Exam tips

Always give the reason for classification, not just the label. Marks go to the risk analysis.
Expect a scenario with a twist: a guarantee, a past practice of top-ups, or a shared plan. Spot it first.
For multi-employer plans, state the condition: DC treatment for a DB plan only when information is insufficient, plus disclosure.
Use the scenario figures in the DC calculation and show the due-versus-paid reconciliation.
In ethics-linked questions, note that misclassifying DB as DC can hide liabilities and flatter profit. Comment on this if the scenario hints at it.

Practice questions from Employee benefits

Defined Contribution vs Defined Benefit Plans: frequently asked questions

What is the main difference between a defined contribution and a defined benefit plan?

In a DC plan the employer's obligation ends with the agreed contributions, so the employee bears the risk. In a DB plan the employer promises a benefit and bears the risk if the fund falls short. This changes the accounting from a simple expense to a measured net liability.

How do you account for a defined contribution plan under IAS 19?

Recognise the contribution payable for the period as an expense, unless another standard permits capitalising it. Show an accrued liability for unpaid contributions or a prepayment if more was paid than due. Discount only if payment is not expected within 12 months after the period in which service was rendered.

How are multi-employer plans classified?

Classify them as DC or DB based on their terms. If the plan is DB and you lack enough information to account for your share, account for it as DC and disclose that fact and the reason.

Can a state plan be treated as defined contribution?

Yes, if the entity's obligations are limited to the contributions due in the period, as the plan's terms usually show. IAS 19 requires state plans to be accounted for in the same way as multi-employer plans. If the obligation goes beyond the period's contributions, account for the plan as DB. The insufficient-information exemption applies only if the state plan is a multi-employer DB plan.
