Auditing a gratuity provision means testing the employee census data sent to the actuary, checking the actuarial valuation report's assumptions and its agreement to the books, and confirming the accounting treatment — actuarial gains and losses through other comprehensive income under Ind AS 19, differently under AS 15 — is applied correctly. Leave encashment is tested the same way in principle, but the underlying data is the leave balance register rather than a census, and that register is frequently the weaker of the two.
Why these two provisions sit together
Gratuity and leave encashment are both long-term employee benefits that depend on an employee staying with the company, and both are usually measured using actuarial techniques because the payment is contingent on future events — continued service, the discount rate, future salary growth, attrition and mortality. The accounting is genuinely more complex than most other payroll line items, which is exactly why the quality of the input data matters more here than the sophistication of the valuation model.
Actuarial valuation basics under Ind AS 19 and AS 15
Companies applying Ind AS follow Ind AS 19, Employee Benefits; companies on the older framework follow AS 15. Both require defined benefit obligations like gratuity to be measured using the projected unit credit method, but they differ in where the resulting gains and losses go — Ind AS 19 routes remeasurements through other comprehensive income with no subsequent recycling to profit or loss, while AS 15 recognizes actuarial gains and losses in the profit and loss account. Confirm which framework applies to the entity and do not carry the other framework's treatment forward from habit.
| Assumption | What it drives | Audit check |
|---|---|---|
| Discount rate | Present value of the obligation | Should reference the yield on government bonds of a term matching the obligation; a rate copied unchanged from the prior year without checking current yields is a common deficiency |
| Salary escalation rate | Projected future salary used to compute the obligation | Compare to the entity's actual historical salary increase pattern; a rate materially below actual increments understates the obligation |
| Attrition / withdrawal rate | Probability an employee leaves before vesting | Compare to the entity's actual attrition experience over recent years, not an industry-generic assumption |
| Mortality rate | Probability of death before retirement | Usually a published standard mortality table; check it is current and consistently applied |
Regulatory requirement
Ind AS 19 and AS 15 require defined benefit obligations to be measured by a qualified actuary using the projected unit credit method, except where a simplified alternative is permitted for entities below the applicable size thresholds. Confirm which standard and which measurement basis apply to the entity before concluding on the valuation.
When a simplified approach is acceptable
Both frameworks recognize that a full actuarial valuation is disproportionate for smaller entities, and permit certain categories of entities — broadly, smaller and non-listed companies meeting defined size criteria — to measure these obligations using a simplified method instead of engaging an actuary. The precise eligibility criteria and the mechanics of the simplified method are set out in the standard itself and have been subject to amendment, so confirm the current text rather than assuming a client's prior-year treatment is still available to them.
- Confirm the entity actually meets the size criteria for using a simplified approach in the year under audit — a company that grew past the threshold mid-year cannot simply continue the prior year's method.
- Where a simplified approach is used, understand what it approximates and whether the approximation is reasonable given the entity's employee profile — a simplified method calibrated for a stable, long-tenure workforce can misstate the obligation for a business with high attrition.
- Where an entity switches between a full actuarial valuation and a simplified approach, or vice versa, check the switch is disclosed and consider whether the change itself needs separate consideration.
Testing the actuarial valuation report
- 01Obtain the actuary's report and confirm it is addressed to the entity for the correct valuation dateA report dated for the wrong period or carried forward from a prior engagement without a current signature is not evidence for this year.
- 02Agree the opening obligation in the report to the closing obligation in the prior year's reportA break here, with no reconciling explanation, usually means the census data changed in a way nobody investigated.
- 03Trace the movement — current service cost, interest cost, actuarial gain or loss, benefits paid — to the accounting entriesEach component has a different accounting destination under Ind AS 19; check each landed in the right place rather than being bundled into one journal entry.
- 04Recompute the net liability recognized in the balance sheetObligation less the fair value of plan assets, where the gratuity is funded through a trust or an insurer-managed scheme. Confirm the fund valuation used is as of the same date as the obligation.
Testing the census and leave balance data
The actuary values whatever data is handed to them. An actuarial report built on an inaccurate employee census or an unreconciled leave balance register produces a precise-looking number that is simply wrong, and this is where most gratuity and leave encashment audit findings actually originate — not in the mathematics of the valuation.
- Agree the census headcount, date of joining, and salary used in the valuation to the employee master as of the valuation date.
- Check employees who exited during the year were removed from the census, and new joiners after the prior valuation date were added, with salary as of the current valuation date rather than carried forward.
- For leave encashment specifically, obtain the leave balance register and reconcile total eligible leave days to the attendance or HR system — a register that has not been reconciled against actual leave taken for several periods tends to accumulate errors that compound every year.
- Check the leave encashment policy — the rate applied per day, any cap on accumulation, and whether encashment is available only on exit or also during service — matches what was actually used in the computation.
- For employees near retirement or resignation, check the gratuity and leave encashment provision was adjusted for the final settlement rather than continuing to accrue on the standard basis.
A leave balance register that has silently drifted from actual attendance records for several years can carry an accumulated overstatement that only becomes visible when an employee actually encashes a large balance on exit. Reconciling the register against attendance data, even on a sample basis, is worth doing even when the year-on-year movement in the provision looks unremarkable.
Disclosure
Ind AS 19 requires extensive disclosure of the defined benefit obligation — a reconciliation of the opening and closing balances, the assumptions used, sensitivity analysis, and the maturity profile of expected future payments. Check the disclosures in the financial statements agree to the actuarial report, including the sensitivity figures, which are frequently copied forward from a template rather than regenerated for the current year's assumptions.
How we think about this
The actuarial calculation itself — applying a discount rate and a mortality table to a census under the projected unit credit method — is specialist work best left to the actuary and then checked by recomputing the movement schedule and tracing it to the books. What an auditor actually adds in this area is scrutiny of the census and leave data quality, because that input is the one nobody else is independently checking, and it is also the one most likely to be wrong.
This is practical guidance written for audit teams, not an authoritative statement of any standard or statute. Standards, forms and timelines change. Check the current text issued by the ICAI and the relevant authority before relying on anything here in an audit file.
