IFRS vs US GAAP: Key Differences Every Business and Finance Professional Must Know
Which framework reports higher profit and when, where Ind AS sits, and what changes for Indian finance teams in 2027.
IFRS vs US GAAP is not a contest between a right answer and a wrong one. It is a difference in timing. Both frameworks measure the same economic events, and over the life of an asset or a contract both arrive at the same total profit. What separates them is the year in which that profit appears, and for a finance team preparing two sets of reporting from one ledger, timing is the entire problem.
For Indian businesses the IFRS vs US GAAP question stopped being theoretical some time ago. Any Indian subsidiary of a United States parent, and every global capability centre in Bengaluru with a US reporting line, prepares Ind AS statutory financial statements for Indian filing and a US GAAP package for group consolidation. Knowing which differences move profit, and in which direction, is what keeps those two outputs reconcilable.
01 — The Root SplitWhy Do the Same Transactions Produce Two Different Profits?
Because the frameworks are written differently at the root. IFRS, issued by the International Accounting Standards Board, states a principle and expects the preparer to apply judgement against it. US GAAP, issued by the Financial Accounting Standards Board, states a rule and expects the preparer to follow it.
Neither approach is loose, but they fail in opposite directions. A principles-based framework adapts to an unusual transaction at the cost of two competent accountants reaching different conclusions. A rules-based framework delivers consistency at the cost of structuring, where a transaction is engineered to land on the favourable side of a bright line. The volume of industry-specific guidance in US GAAP is also far greater, which accounts for the sheer difference in length between the two bodies of literature.
One structural point is easy to miss. IFRS is a single body of standards applied across more than 140 jurisdictions, whereas US GAAP sits alongside Securities and Exchange Commission regulations that impose further presentation and disclosure requirements on registrants. Comparing the two honestly means comparing IFRS with US GAAP plus the SEC rulebook.
02 — Higher ProfitWhich Framework Reports the Higher Profit?
It depends entirely on which difference you are looking at and where you are in the asset's life. The table below sets out the direction of effect for the differences that recur most often in Indian reporting packages.
| Difference | Higher Reported Profit | Why |
|---|---|---|
| Development costs | IFRS, in the spend year | IAS 38 capitalises once criteria are met; US GAAP expenses as incurred |
| LIFO in a rising market | IFRS | US GAAP permits LIFO, raising cost of sales; IAS 2 prohibits it |
| Inventory write-down reversal | IFRS | IFRS reverses when net realisable value recovers; US GAAP forbids reversal |
| Impairment reversal | IFRS | Permitted for assets other than goodwill; never permitted under US GAAP |
| Year an impairment is triggered | US GAAP | The undiscounted screen delays recognition; IFRS tests on a discounted basis |
| Early years of a lease | US GAAP | ASC 842 straight-lines an operating lease; IFRS 16 front-loads every lease |
| Origination of a receivable | IFRS | IFRS 9 stages the loss; ASC 326 recognises lifetime losses from day one |
Read the table as a set of timing switches rather than a scoreboard. IFRS recognises impairment earlier and reverses it later; US GAAP defers recognition and never reverses. IFRS front-loads lease cost; US GAAP spreads it. Revenue recognition is the reassuring exception. IFRS 15 and ASC 606 came out of a joint project and remain substantially aligned, so revenue recognition rarely drives a reconciling item at all — which is worth knowing before a team spends weeks testing it.
03 — Balance SheetWhere Do the Differences Show Up on the Balance Sheet?
Three areas carry most of the balance sheet divergence, and each has a direct consequence for the covenants and ratios a lender or parent will be watching. Unlike revenue recognition, none of these has been converged by a joint project.
- Asset carrying values. Under IAS 16 and IAS 38 an entity may elect a revaluation model for property, plant and equipment and for intangibles traded in an active market. No such election exists in US GAAP, where historical cost governs and upward revaluation is simply unavailable. An asset-heavy Indian entity can therefore look materially different on the two balance sheets before a single transaction is compared.
- Capitalised intangibles. Development costs meeting the IAS 38 criteria sit on the IFRS balance sheet as an intangible asset and nowhere on the US GAAP one. For a product or engineering business this affects both total assets and the depreciation and amortisation line for years afterwards.
- Lease balances. Both frameworks now put leases on the balance sheet, so lease accounting differs in the expense profile rather than the presence of the asset. Under IFRS 16 a lease produces depreciation and interest; ASC 842 produces a single operating lease expense. Interest cover and EBITDA move accordingly.
Lease accounting deserves particular attention because it touches every covenant a lender tests. Component depreciation is a further quiet difference. IFRS requires significant parts of an asset with different useful lives to be depreciated separately, which US GAAP permits but rarely applies in practice.
Note — Build the difference register before the first reporting cycle, not after the first audit query. For most Indian entities the list is shorter than expected — inventory costing, development costs, leases, impairment and employee benefits will cover the majority of recurring adjustments. What matters is that each entry names the standard on both sides and the person responsible for it.
04 — Who Needs BothWhich Indian Businesses Actually Need Both Frameworks?
More than most people assume, and Bengaluru holds a heavy concentration of them. Any Indian entity with a foreign reporting line runs two frameworks off one ledger.
Global capability centres are the clearest case. A captive serving a United States parent files Ind AS statutory financial statements in India and delivers a US GAAP reporting package upstream every month. Beyond the GCCs, the same pressure reaches Indian companies raising capital abroad, groups pursuing an overseas listing, and any business facing diligence from an international acquirer, where questions arrive framed in IFRS or US GAAP rather than Ind AS. Chartered Accountants in Bangalore see the pattern repeatedly: the statutory audit is straightforward and the group package is where the work sits.
Ind AS is close to IFRS but is not the same standard. It is prescribed under Section 133 of the Companies Act, 2013 and notified through the Companies (Indian Accounting Standards) Rules, 2015, and India chose convergence rather than adoption, so carve-outs remain. Ind AS 103, for instance, routes a bargain purchase gain to capital reserve through other comprehensive income where IFRS 3 recognises it in profit or loss. A company reporting under Ind AS therefore cannot describe its financial statements as IFRS-compliant without a separate assessment. Standards and exposure drafts are published by the ICAI.
The practical consequence is that IFRS vs US GAAP is rarely a choice an Indian entity gets to make. The parent decides the group framework, the Companies Act decides the statutory one, and the finance team is left to reconcile between them every month. Chartered Accountants in Bangalore advising captives usually find the reconciliation is not technically difficult so much as poorly documented, with adjustments carried forward year to year that nobody can any longer explain.
Whether Ind AS applies at all turns on net worth and listing status. The first phase caught listed companies and unlisted companies at or above ₹500 crore of net worth for financial years from 1 April 2016; the second brought in the remaining listed companies and unlisted companies at or above ₹250 crore from 1 April 2017. Group membership then overrides size, since a covered company pulls its holding, subsidiary, joint venture and associate companies in behind it, and the election cannot be reversed.
05 — 2027 ChangesWhat Changes in IFRS vs US GAAP in 2027?
A great deal, and not in the direction of convergence. Each board has decided independently that the income statement tells readers too little about costs, and each has legislated a fix that the other has not adopted. The two remedies land within weeks of one another.
On the IFRS side, IAS 1 gives way to IFRS 18 for annual reporting periods beginning on or after 1 January 2027. Issued in April 2024, it sorts income and expenses into defined categories on the face of the profit or loss statement, adds mandatory subtotals, and forces any management-defined performance measure the company quotes publicly into the notes with a reconciliation back to an IFRS figure. Rules on when items may be grouped together also tighten. Adoption is retrospective, which pulls the comparative year into scope.
The United States is addressing the same concern from the opposite end. The FASB standard on disaggregation of income statement expenses requires public business entities to break out expense captions into natural categories such as employee compensation, depreciation and amortisation, in tabular form in the notes. It applies to annual reporting periods beginning after 15 December 2026, aligning almost exactly in timing with IFRS 18 while leaving the face of the income statement untouched.
For anyone maintaining an IFRS vs US GAAP bridge, this is the change that demands attention first, because it alters presentation rather than measurement and therefore touches every line rather than a handful.
India trails IFRS by a few months. An exposure draft for Ind AS 118, converged with IFRS 18, was put out by the ICAI in January 2025 with a proposed commencement of 1 April 2027 and retrospective application, and the National Financial Reporting Authority backed adoption in January 2026. Notification by the MCA has not yet come through.
Important — One ledger, three commencement dates. The US disaggregation rules bite first, for annual periods beginning after 15 December 2026. IFRS 18 follows for periods beginning on or after 1 January 2027. Ind AS 118 is proposed for 1 April 2027 and is not yet notified. A captive with a US reporting line and an Indian statutory framework therefore restates comparatives against three separate calendars, and because each is retrospective the comparative year is already being lived through. Ledger and reporting changes belong in this year's plan, not next.
06 — ReconcilingHow Do You Reconcile IFRS vs US GAAP in Practice?
Seven steps, in this order. A GAAP reconciliation assembled at year-end from memory is the item auditors test hardest and the one most likely to fail.
Confirm which framework governs which statement. Establish in writing whether the Indian statutory statements fall under Ind AS or the earlier Accounting Standards, and which framework the group package requires. For an Indian subsidiary the statutory framework is fixed by law, and only the US GAAP reporting line is a matter of group policy. Everything built on a wrong answer here has to be rebuilt.
List every recurring difference with its standard reference. Name the standard on both sides for each item, the direction of the adjustment, and the person responsible. This register is the reconciliation; the spreadsheet is only its arithmetic.
Fix the measurement inputs that drive the largest gaps. Lease accounting discount rates, impairment cash flow models and expected credit loss assumptions produce the biggest divergences. Agree the methodology and document it before year-end rather than during fieldwork.
Capture data once, at the lowest level. Design the chart of accounts so each framework aggregates the same underlying data differently. Retrofitting after IFRS 18 takes effect is materially harder than designing for it now.
Reconcile profit and equity separately. A bridge that ties profit but not closing equity is incomplete, because timing differences accumulate on the balance sheet even when the current year movement agrees.
Align the two reporting calendars. Indian statutory deadlines and the parent consolidation timetable rarely coincide. Map both and identify where a hard close is needed to serve two masters in the same month.
Have the bridge independently reviewed. A GAAP reconciliation prepared and checked by the same team has not been tested. An external review before the audit costs considerably less than an audit adjustment during it.
07 — Since LiberalisationHow Did Two Frameworks End Up Competing?
Because accounting standards were built to serve national capital markets, and capital stopped respecting national boundaries. India's position in that story tracks the opening of its own economy almost exactly.
Before 1991, under the licence-permit regime, Indian financial reporting answered to domestic banks, promoters and the tax authorities. The Accounting Standards issued by the Institute of Chartered Accountants of India from the late 1970s served that audience adequately, and international comparability was not pressing because foreign investment was tightly restricted.
What 1991 changed first was the readership, not the rulebook. Capital came in from abroad, and by the late 1990s Indian issuers were listing depositary receipts on American exchanges, which meant producing or reconciling to US GAAP for a regulator in another jurisdiction. An Indian balance sheet suddenly had to be legible to someone with no exposure to Indian GAAP whatsoever.
Domestic standards closed the distance across 2013 to 2017. Section 133 of the Companies Act, 2013 supplied the statutory authority, the Companies (Indian Accounting Standards) Rules, 2015 laid out the phasing, and Ind AS took effect in two waves from April 2016 and April 2017. GST arrived on 1 July 2017 and rewrote indirect taxation without touching the reporting framework at all, a separation worth holding on to. India converged rather than adopted, and that single decision is why the IFRS vs US GAAP question is still answered with a reconciliation instead of a translation.
FAQFrequently Asked Questions
These are the questions Indian finance teams raise most often on IFRS vs US GAAP, answered against the position as it stands in 2026. Further material is published on our blog, and groups wanting a structured review can partner with us.
Why does the same company report a different profit under IFRS and US GAAP?
Because the two frameworks recognise the same economic events at different times. Development expenditure is capitalised under IFRS once the criteria are met but expensed as incurred under US GAAP. An impairment loss can be reversed under IFRS but never under US GAAP. A lease is front-loaded under IFRS 16 but straight-lined for an operating lease under ASC 842. None of these differences changes the total profit over the life of the asset or contract; they change the year in which it appears.
Is LIFO allowed in India?
No. LIFO is prohibited under Ind AS 2 and under IAS 2, and it has never been permitted in Indian financial reporting. It remains available under US GAAP, which is why an Indian subsidiary of a United States parent that uses LIFO must maintain FIFO or weighted average costing for its Indian books while the group carries a LIFO reserve adjustment on consolidation. This is one of the most common recurring reconciling items for Indian entities.
What is a GAAP bridge and who prepares it?
A GAAP bridge is a documented reconciliation that moves reported profit and equity from one framework to another, line by line, with a reference to the standard driving each adjustment. It is normally prepared by the Indian finance team and reviewed by the group controller or an external adviser. A bridge prepared and checked by the same person is a bridge nobody has tested, which is why an independent review before the audit is cheaper than an audit adjustment after it.
Do Indian GCCs have to maintain two sets of books?
One set of books, two sets of reporting. A global capability centre keeps a single accounting ledger and prepares statutory financial statements under the framework applicable in India, which is Ind AS where the roadmap applies. It then produces a separate reporting package under the parent framework for consolidation. The statutory statements govern the Indian audit, filing and tax position; the group package does not.
Will IFRS 18 bring IFRS and US GAAP closer together?
Not on presentation. Both boards are addressing expense transparency at almost the same time but in different ways. IFRS 18 restructures the face of the statement of profit or loss into defined categories with new mandatory subtotals, while the United States rules add disaggregated expense tables in the notes and leave the income statement itself unchanged. The effect is that presentation differences between the two frameworks widen rather than narrow.
