In short

IFRS is principles-based, US GAAP is rules-based, and Ind AS — India's IFRS-converged framework — follows IFRS's principles with specific India carve-outs. The two dominant global standards agree closely on revenue recognition and goodwill, but diverge materially on inventory (LIFO), leases, development costs, and PPE revaluation — differences that directly affect reported profit and equity for Indian IT, pharma, and manufacturing businesses with cross-border reporting obligations.

IFRS vs US GAAP is one of the most searched accounting topics among Indian finance professionals — and for good reason. As India integrates further with global capital markets, as Indian companies seek listings on US exchanges, and as growing tech and pharma sectors attract foreign direct investment from both US and European companies, understanding the key differences between these two dominant accounting frameworks has moved from a theoretical exam question to a daily professional necessity.

For Indian finance professionals and business owners, this topic carries an added layer of complexity: India does not follow IFRS directly, nor does it follow US GAAP. Instead, the Ministry of Corporate Affairs (MCA) introduced Ind AS — Indian Accounting Standards — substantially converged with IFRS but carrying specific India-relevant carve-outs. An Indian CFO or CA needs to understand where IFRS and US GAAP differ, where Ind AS aligns with IFRS, and where India's own standards diverge from both. This guide covers all three dimensions clearly and practically — and since a new company is often where this question first comes up, it's worth starting with a clean structure via company registration that already anticipates which framework you'll eventually report under.

01What are IFRS, US GAAP, and Ind AS — and how does India fit in?

Understanding the three-framework landscape is the essential starting point for any Indian finance professional dealing with international accounting standards.

IASB · London

IFRS

Adopted or permitted in 140+ countries including the EU, UK, Australia, Canada and Singapore. Principles-based: broad objectives, with management applying professional judgement to specific transactions.

FASB · Norwalk, CT

US GAAP

The SEC recognises FASB standards as authoritative for all domestic US-listed companies. Rules-based: highly detailed, prescriptive guidance for virtually every transaction type.

MCA / ICAI · India

Ind AS

Introduced in phases from FY 2016-17 for listed and large unlisted companies (net worth above ₹250 crore). Carries the same numbering as IFRS with specific India carve-outs.

Critical point for Indian readers

This guide focuses on IFRS vs US GAAP. Where Ind AS aligns with IFRS — which it does in most areas — the IFRS column below also reflects Ind AS. Where Ind AS has a specific India carve-out, that's called out explicitly.

03Principles-based (IFRS/Ind AS) vs rules-based (US GAAP)

The most fundamental structural difference between IFRS and US GAAP — which Ind AS inherits from IFRS — is the principles-based vs rules-based distinction. For Indian finance professionals trained on Ind AS, transitioning to US GAAP reporting for a US parent or a US listing can feel counterintuitive: the answer to many accounting questions is no longer "apply judgement," it's "find the specific rule."

IFRS / Ind AS — Principles

The standard establishes the objective and gives broad guidance. Management applies professional judgement — two companies facing economically identical transactions may reach different, both defensible, conclusions. The auditor assesses whether the judgement is reasonable, not whether it matches a specific rule.

US GAAP — Rules

FASB produces detailed guidance — sometimes hundreds of pages — for specific transaction types, industries and edge cases. The accountant's job is to identify the applicable rule and apply it. This reduces diversity in practice, but has historically enabled sophisticated structuring to hit a desired accounting outcome while technically staying within the rules.

For Hyderabad's IT sector: moving from Ind AS thinking to US GAAP reporting requires a mindset shift — from "what is the economic reality" to "what does the specific standard say." Business advisory support during this transition typically pays for itself in avoided reconciliation errors alone.

04Inventory accounting: why LIFO matters for Indian businesses trading with the US

The LIFO (Last-In First-Out) inventory method is one of the most practically significant IFRS vs US GAAP differences for Indian businesses — particularly trading companies, manufacturers, and Indian subsidiaries of US corporations.

IFRS / Ind AS 2

Explicitly prohibits LIFO. Indian companies must use FIFO or Weighted Average Cost — non-negotiable for Ind AS preparers. A write-down to Net Realisable Value can be reversed if NRV later recovers.

US GAAP · ASC 330

Permits LIFO, FIFO, and Weighted Average Cost. Many US companies in oil and gas, chemicals, and wholesale distribution use LIFO to match higher recent costs against revenue during inflation. Once written down, inventory value becomes the new permanent cost basis — reversal is never permitted.

This creates a specific challenge for Indian subsidiaries of US LIFO-using companies. The Indian subsidiary prepares its Ind AS books on FIFO or Weighted Average; the US parent consolidates on LIFO. The subsidiary's accountants must understand the LIFO reserve adjustment required for US GAAP consolidation — a reconciliation item that affects both reported profit and inventory values in the group accounts.

Illustrative exampleInd AS books (Weighted Average)US GAAP consolidation (LIFO)
Closing inventory valueHigher — reflects recent purchase costsLower — LIFO reserve deducted
Reported COGSLowerHigher — most recent costs expensed first
Write-down in a bad quarter, then recoveryCan be written back up to NRVStays at the written-down amount permanently

For Indian manufacturers and commodity traders with volatile input prices, the reversal-policy gap alone can produce materially different reported results between Ind AS and US GAAP in recovery periods.

05Revenue recognition: IFRS 15, ASC 606 & Ind AS 115

Revenue recognition is the area where IFRS and US GAAP have converged most successfully — and where Ind AS tracks closely with both. All three frameworks are built on the same five-step model developed jointly by the IASB and FASB.

  1. Identify the contract with the customerA contract exists when it has commercial substance, the parties have approved it, and collection is probable.
  2. Identify the performance obligationsSeparate promises to deliver distinct goods or services are identified individually.
  3. Determine the transaction priceThe consideration the entity expects to be entitled to.
  4. Allocate the transaction priceDistributed across performance obligations by relative standalone selling price.
  5. Recognise revenueWhen (or as) control of the good or service transfers to the customer.

Despite this convergence, practical differences remain:

  • Software licensing — treatment of IP licences (right to access vs right to use) can differ between IFRS 15 and ASC 606 in specific fact patterns. Ind AS 115 follows IFRS 15.
  • Variable consideration — detailed guidance on constraining variable consideration (volume rebates, performance bonuses) differs between the three, though the overall principle is shared.
  • Practical expedients — each framework offers a slightly different set of expedients for short-term contracts, immaterial items, and modified retrospective transition.

For Hyderabad's large IT sector — which commonly deals with multi-element software arrangements, SaaS contracts, and project-based revenue — these detailed differences are highly relevant. A Hyderabad IT company reporting under Ind AS 115 while also preparing a US GAAP reconciliation for a US parent or listing will find the underlying principles identical, but specific judgements can diverge.

Practical note for Indian IT companies

The most common area of IFRS 15 / Ind AS 115 vs ASC 606 difference for Indian IT firms is the treatment of contracts with significant customisation, contract modifications, and the variable consideration constraint on time-and-material projects. Review these specifically with a CA for each US GAAP reconciliation.

06Lease accounting: IFRS 16, ASC 842 & Ind AS 116

Lease accounting caused the most operational disruption for Indian companies when Ind AS 116 became effective in FY 2019-20 — and understanding how it compares to ASC 842 is essential for companies with cross-border reporting obligations.

IFRS 16 / Ind AS 116

A single on-balance-sheet model for virtually all leases (minor exceptions for short-term leases under 12 months and low-value assets). The lessee recognises a Right-of-Use asset and lease liability; rent expense is replaced by ROU depreciation plus interest on the lease liability — front-loading total lease cost.

ASC 842

Retains the operating vs finance lease distinction. Both appear on the balance sheet as ROU assets and liabilities, so the balance-sheet impact is broadly similar to IFRS 16 — but operating leases still produce a single straight-line lease expense in the income statement. Finance leases behave like IFRS 16.

For Indian companies — particularly large IT firms in Hyderabad with significant office-space leases, retail chains, and hospitality businesses — Ind AS 116 brought substantial amounts onto the balance sheet that were previously off it. Debt-to-Equity increased, EBITDA increased (rent moved below EBIT), and Return on Assets decreased.

The consequence: an Indian company preparing a US GAAP reconciliation from its Ind AS books for operating leases will show different EBIT, EBITDA, and total lease expense than its Ind AS statements — even though the balance-sheet ROU figures are similar. Accounting & bookkeeping support that covers Ind AS 116 transition adjustments, incremental borrowing rate determination, and lease modification accounting can catch this before it reaches the auditor.

07Development costs, PPE revaluation & goodwill

Development costs: capitalise (IFRS/Ind AS) vs expense (US GAAP)

Under IAS 38 and Ind AS 38, development costs — applying research findings to a plan for a new product or process — must be capitalised as an intangible asset once six specific criteria are met: technical feasibility, intention to complete, ability to use or sell, availability of resources, reliable measurement, and probable future economic benefits. Under US GAAP (ASC 730), virtually all R&D costs are expensed immediately, with the main exception being internal-use software development costs (ASC 350-40).

For Hyderabad's large pharma and IT sectors, this difference is highly significant. A Hyderabad pharma company capitalising clinical trial development costs under Ind AS 38 will show higher reported profit and higher intangible assets than the same company would under US GAAP. For a US-listed Indian pharma company preparing a US GAAP reconciliation, reversing Ind AS-capitalised development costs is typically one of the largest reconciling items between Indian GAAP profit and US GAAP profit.

Illustrative example — pharma R&DInd AS 38 (capitalise)US GAAP / ASC 730 (expense)
Qualifying development spend this yearRecognised as an intangible assetExpensed immediately through P&L
Reported profit this yearHigherLower
Reported intangible assetsHigherUnchanged (no capitalisation)

PPE revaluation model

Ind AS 16 and IAS 16 let companies choose between the cost model and the revaluation model for Property, Plant and Equipment. Under revaluation, assets are carried at fair value with surpluses recognised in Other Comprehensive Income. US GAAP (ASC 360) permits only the cost model — always historical cost less accumulated depreciation. For Indian real-estate-heavy businesses, infrastructure companies, and manufacturers with significant land or buildings, the revaluation model can produce substantially higher reported equity under Ind AS than the same assets would show under US GAAP.

Goodwill: one area of alignment

This is one area where IFRS, US GAAP, and Ind AS now broadly agree. All three no longer amortise goodwill — it's subject to an annual impairment test (plus a trigger-based test when indicators arise). Testing methodology differs in detail between IFRS/Ind AS and US GAAP, but the no-amortisation principle is shared. This wasn't always so — IFRS adopted no-amortisation in 2004, the US in 2001. Where goodwill and ROC filings intersect for group restructurings, ROC compliance support helps keep the statutory and accounting pictures consistent.

Important

For companies navigating the transition from Ind AS to a US GAAP reporting requirement — a US listing, a US parent consolidation, or investor due diligence — a structured assessment of the reconciling items specific to your business is worth doing early, not at audit time.

08How did IFRS and US GAAP evolve — and why did India choose convergence over adoption?

The history of global accounting standards is a story of competing visions, regulatory politics, and the practical limits of international consensus. Scroll sideways through the timeline.

Pre-1970s

Every country for itself

Accounting standards were purely national — the UK, USA, Australia, Canada and most European countries kept entirely separate frameworks. The IASC formed in 1973 — later the IASB — driven by the need for a common language for global capital markets.

1990s–2002

The Enron era

Through the 80s and 90s, US GAAP was considered the gold standard. The 2001 Enron collapse, then WorldCom and Tyco, challenged that view — each scandal involved aggressive use of specific US GAAP rules to misrepresent economic reality. Principles-based IFRS was held up as a potential antidote.

2002–2012

Convergence and India's decision

The 2002 Norwalk Agreement committed the IASB and FASB to convergence; the EU's 2005 IFRS mandate for listed companies was the single biggest event in global IFRS adoption. India chose not to adopt IFRS outright and instead built the Ind AS convergence project.

2013–2026

Convergence stalls; Ind AS becomes established

By 2014 both boards had effectively acknowledged a single global standard wasn't near-term achievable. Ind AS became mandatory for listed companies from FY 2016-17 and for large unlisted companies in phases through 2020. Work continues at ifrs.org and fasb.org.

For Indian businesses in 2026, the practical reality is three parallel frameworks — Ind AS as the home standard, IFRS as the language of international investor communication, and US GAAP as the requirement for any US market engagement.

09Who needs to act

Hyderabad IT company with a US parent or ADR listing

Development costs, revenue recognition on multi-element contracts, and lease accounting are the three biggest reconciling items — plan the review cadence around each quarter-end.

Pharma / life-sciences company

Clinical trial and R&D capitalisation under Ind AS 38 vs immediate expensing under ASC 730 is usually the single largest reconciling item to a US GAAP profit figure.

Real estate, infrastructure & manufacturing

The PPE revaluation model can materially inflate reported equity versus what the same assets would show under US GAAP — flag this early for any US-facing valuation.

Indian subsidiary of a US corporation

LIFO reserve reconciliation for inventory consolidation, plus lease expense presentation differences under ASC 842, are the recurring month-end adjustments.

Company preparing for a US listing

Foreign private issuers can generally file under full IFRS without a US GAAP reconciliation — but Ind AS accounts still need conversion to full IFRS first.

CFO or finance manager building a cross-border team

Training Ind AS-fluent staff to think in "find the rule" terms for US GAAP is a deliberate change-management exercise, not a one-off memo.

10Frequently asked questions

Alongside the accounting-framework questions below, many of the same businesses are also juggling income tax and ITR filing deadlines — worth handling on the same advisory track rather than separately.

Ind AS is substantially converged with IFRS — the same five-step revenue model (Ind AS 115 = IFRS 15), the same lease accounting model (Ind AS 116 = IFRS 16), the same financial instrument standard (Ind AS 109 = IFRS 9). However, Ind AS includes India-specific carve-outs: the option to use the cost model only for PPE rather than mandating a revaluation option, specific modifications to employee benefit accounting under Ind AS 19 compared to IAS 19, different transition provisions, and exemptions for certain regulated industries.

Foreign private issuers — which most Indian companies listed in the US qualify as — are permitted to file financial statements prepared under IFRS as issued by the IASB without a US GAAP reconciliation. Companies filing under Ind AS (rather than full IFRS) are technically required to reconcile to US GAAP, since the SEC does not accept Ind AS without reconciliation. In practice, most Indian companies seeking US listings convert their accounts to full IFRS for SEC filing purposes.

Three areas matter most: software development costs (IFRS/Ind AS capitalise, US GAAP expenses immediately), revenue recognition on complex multi-element contracts, and lease accounting — Ind AS 116 and IFRS 16 produce higher EBITDA than ASC 842 for operating leases due to the single-model income statement treatment.

LIFO — widely used by US companies for tax benefits — is prohibited under IFRS, and eliminating it would trigger substantial one-time tax liabilities. The SEC and FASB have invested decades in the US GAAP codification and are reluctant to cede standard-setting authority to an international body. US markets function effectively under the current framework, so the case for a disruptive transition isn't compelling to US stakeholders.

Neither is uniformly more conservative. US GAAP is more conservative on development costs and write-down reversals; IFRS is more conservative in prohibiting LIFO. Overall, IFRS-reporting companies tend to show higher assets and equity, while US GAAP companies may show lower taxable income but higher reported gross margins.

An experienced CA firm can conduct an Ind AS-to-IFRS gap analysis for overseas listings, prepare US GAAP reconciliations for US parent companies, advise on differences affecting reported profit and equity, and coordinate with international auditors reviewing the reconciliation.
