The practical difference an auditor has to actually test, moving a client from AS (old Indian GAAP) to Ind AS, is that Ind AS requires fair value and expected-loss-based measurement in several areas where AS used historical cost or an incurred-loss model — financial instruments, investment property, certain PP&E components, leases, and provisions — so the audit work isn't a restatement exercise, it's independently re-evaluating measurement judgments the client may never have had to make under AS at all.
Where the numbers actually move, area by area
| Area | Old AS treatment | Ind AS treatment | What the auditor has to test differently |
|---|---|---|---|
| Financial instruments | Cost or amortised cost, incurred-loss provisioning | Classification by business model, fair value through P&L/OCI, expected credit loss (Ind AS 109) | Management's ECL model and assumptions — a new estimate that didn't exist under AS |
| Leases | Operating vs finance lease split; operating leases off balance sheet | Nearly all leases on balance sheet as right-of-use assets and lease liabilities (Ind AS 116) | Completeness of the lease population and discount rate used to measure the liability |
| Property, plant and equipment | Component accounting optional in practice | Component accounting required where useful lives differ materially | Whether significant components are actually separately identified and depreciated |
| Business combinations | Pooling of interests more commonly used; goodwill amortised | Acquisition method with fair value of consideration and identifiable assets/liabilities; goodwill tested for impairment, not amortised | Purchase price allocation and the annual impairment test replacing amortisation |
| Revenue | Risk-and-reward based recognition, often less granular | Five-step model under Ind AS 115, with separate performance obligations | Whether revenue has actually been re-analysed into obligations, not just relabelled |
What the first-time adoption reconciliation has to show
- 01Opening Ind AS balance sheet at the transition dateEvery adjustment from the last AS balance sheet to the Ind AS opening balance sheet has to be identified and quantified — not summarised as a single net adjustment to retained earnings.
- 02Reconciliation of equity at the end of the last AS reporting period and the transition dateRequired disclosure under Ind AS 101 — this is the document that should drive most of the audit testing on the transition itself.
- 03Reconciliation of total comprehensive income for the latest period reported under ASShows where profit or loss itself, not just balance sheet items, moved under the new measurement bases.
An opening Ind AS balance sheet with no adjustments to retained earnings, on a first-time adopter with leases, financial instruments or a prior business combination on the books, is itself a red flag — it usually means the transition exercise wasn't actually performed with the required mandatory exceptions and optional exemptions properly applied, rather than that the AS numbers happened to already comply with Ind AS.
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.
