Learn the basics of US GAAP accounting as an Indian finance professional with this practical guide. Learn key differences from IFRS/Ind AS, understand the rules-based approach, and follow my simple 8-12 week plan to build the skills needed for global opportunities—all explained through real-world examples.
Introduction
“I thought I knew everything about accounting, but US GAAP made me feel like a first-year trainee.“
That is what my friend Priya (name changed) told me, looking tired at our regular coffee shop in Khar.
Priya is a CA who represents the common experiences of Indian finance professionals facing these transitions.
She had worked at a big accounting firm for eight years and was known as the expert when it came to Indian accounting rules (called Ind AS).
But now, in her new job, where she had to prepare reports for an Indian IT giant, she was struggling.
“It is not just different rules,” she said, showing me a confusing report about how to record revenue. “It is like they think about accounting in a completely different way.“
For Indian finance professionals well-versed in IFRS or Ind AS, stepping into the world of US GAAP can feel like navigating a parallel universe.
Yes, the basics of accounting are still there — assets, income, expenses, cash flows. But the way US GAAP handles the details, uses terms, and expects things to be presented can be very different. Even experienced professionals like Priya can find it hard at first.
But why am I telling you all this?
It is because the global finance teams are becoming increasingly interconnected, Indian professionals are finding more opportunities in
- US-based companies,
- Big 4 firms and
- remote-first startups with American clients.
So, mastering US GAAP is no longer optional but a strategic necessity.
In line with this global shift, I am dropping this comprehensive guide, breaking down exactly what you need to know to get through this transition.
I will not just talk about technical differences, but the mindset shifts that separate those who struggle from those who thrive.
What makes US GAAP fundamentally different
Many Indian finance professionals initially approach US GAAP, thinking it is simply IFRS with a few American twists and modifications. But there is a much richer opportunity here for those who dig deeper.
While IFRS and US GAAP might seem like cousins that share accounting DNA, they actually represent two distinct ways of approaching financial reporting, each with its own strengths. Recognising this fundamental difference is not just academic. It is the key insight that will accelerate your transition and open doors to global opportunities.
Rules vs Principles — The core philosophical divide
Let me paint you a picture of the fundamental difference.
Imagine you are driving in Delhi.
The traffic rules exist, but everyone interprets them based on the situation. You adjust your driving based on conditions, traffic flow, and what makes practical sense. That is closer to IFRS — principles-based, requiring judgment, allowing flexibility.
Now, imagine driving in Manhattan.
Every turn, every lane change, every parking rule is precisely defined. There is a specific procedure for everything, with clear penalties for deviations. That is closer to US GAAP — more rules-based with detailed guidance.
However, while US GAAP is often described as rules-based, it incorporates principles in areas like revenue recognition. Similarly, Ind AS can be quite prescriptive in certain areas, such as lease accounting. Understanding this spectrum will help you navigate both frameworks more effectively.
The IFRS/Ind AS approach:
- Start with the principle: “Recognise revenue when control transfers.“
- Apply professional judgment to the specific situation
- Document the reasoning
- Multiple acceptable outcomes are possible
The US GAAP approach:
- Start with detailed guidance: “ASC 606-10-25-23 through 25-26”
- Follow specific tests and thresholds
- Limited judgment required
- Usually, one “correct” answer
Here, let me give you an example:
Let us say a software company sells a package that includes both their software and after-sales services to help set up the software. Think of it like buying a new phone (the software) and having someone help you transfer all your data and set up your accounts (the setup service).
Under Ind AS (India’s version of IFRS), an accountant would ask: “Do these two things naturally go together? Would customers typically buy them together?” Using their professional judgment, they might decide these services are so connected that they should be treated as one package deal for accounting purposes.
Under US GAAP, there is a detailed checklist to follow:
- Can the customer use the software on their own? (Yes/No)
- Is the setup service available from other companies? (Yes/No)
- Could the software work without this specific setup? (Yes/No)
Following this strict checklist might lead to treating them as two separate items, regardless of what might seem logical in the real business context.
“At first, I felt constrained,” Priya admitted when learning US GAAP. “Then I realised — there is less second-guessing. Less debate with auditors. In some ways, it is liberating to just follow the rules.“
Understanding the regulatory frameworks
Let me explain how the US financial reporting system works compared to India’s.
Both countries have developed multi-layered regulatory structures that serve different but complementary functions.
US financial reporting system
In the US, the system operates with three primary authorities working in concert:
FASB (Financial Accounting Standards Board):
- Creates and updates US GAAP
- Issues Accounting Standards Codification (ASC)
- Responds to emerging issues through deliberation
For example, when companies started offering complex cryptocurrency transactions, the FASB stepped in to provide guidance.
They formed a working group, collected stakeholder input, and eventually issued specific accounting standards that companies must follow. This deliberative process often takes months or even years, much more structured than you might be accustomed to.
SEC (Securities and Exchange Commission):
- Enforces compliance for public companies
- Issues additional reporting requirements
- Reviews filings and issues comment letters
Here is what this means for you: If you are preparing financial statements for a US-listed company, the SEC will scrutinise your disclosures thoroughly.
For instance, an Indian IT company filing its 10-K (annual report) may receive a letter from the SEC requesting clarification on several aspects of its reporting.
These letters vary significantly in scope – some may focus on revenue recognition, while others might address segment reporting or internal controls.
Some require minor adjustments while others need detailed revisions based on the filing’s complexity.
This level of regulatory review is similar to what SEBI conducts for listed entities in India, though the process differs.
PCAOB (Public Company Accounting Oversight Board):
- Oversees auditors of public companies
- Sets auditing standards
- Inspects audit quality
Let me put this in perspective: The auditors in the US are themselves being audited. The PCAOB conducts rigorous inspections of audit firms, examining specific engagements in detail.
The PCAOB conducts periodic inspections of audit firms, reviewing selected engagements to assess compliance with auditing standards. This oversight system encourages auditors to maintain robust documentation, which often exceeds what you might be accustomed to providing under Indian standards.
These inspections occur annually for large firms and triennially for smaller ones, focusing on a sample of engagements rather than every audit.
India’s financial reporting system
India’s system, while structured differently, has evolved to incorporate similar layers of oversight, particularly for listed companies:
ICAI (Institute of Chartered Accountants of India):
- Develops and recommends accounting standards
- Regulates the accounting profession
- Provides interpretations and guidance
MCA (Ministry of Corporate Affairs):
- Notifies accounting standards under the Companies Act, making them legally binding
- Oversees corporate compliance broadly
- Enforces standards through the Companies Act mechanisms
SEBI (Securities and Exchange Board of India):
- Regulates listed companies similar to the SEC
- Issues additional disclosure requirements
- Reviews compliance for public companies
NFRA (National Financial Reporting Authority):
- Established more recently as an independent regulator
- Oversees the auditing profession for public interest entities
- Functions similarly to the PCAOB in audit oversight
The Sarbanes-Oxley Act of 2002 (SOX) added another layer of compliance that you need to understand.
Under SOX, CEOs and CFOs must personally certify the accuracy of financial statements, ensuring robust internal controls and facing potential liability for material misstatements. Internal control testing became mandatory, requiring exhaustive documentation of every significant process.
This is somewhat parallel to India’s Companies Act provisions on internal financial controls, though typically with more detailed implementation requirements.
My fictional colleague Priya, who transitioned from Ind AS to US GAAP, summed it up perfectly when she said: “Both countries have rigorous systems, but they emphasize different things. Understanding these nuances is crucial for successful navigation of either framework.”
Financial statement presentation – same numbers, different story
Now that you understand who runs the show in US financial reporting, let us talk about something you will deal with immediately: how to present your financial statements.
You might think, “Numbers are numbers, right?” Not exactly.
The same financial data can look completely different depending on which accounting system you are using.
Anyways, if you have worked under IFRS internationally, you might have enjoyed a bit more flexibility, like choosing how to order your balance sheet or classify expenses. Under Ind AS in India, the Companies Act requires a stricter format, limiting some of that flexibility.
In the US system, the degree of flexibility depends on whether you are dealing with public or private companies:
Format and structure requirements:
When I prepared my first US GAAP financial statements for an SEC registrant (public company), I was struck by the specific formatting requirements. Regulation S-X (the SEC’s rule book for financial statements) prescribes detailed formats that public companies must follow.
For example, SEC registrants must present current assets before non-current assets – often the opposite of what many Indian companies do. However, private companies under US GAAP have more presentation flexibility than SEC registrants, such as:
- The option to omit certain disclosures (like segment reporting under ASC 280)
- Less rigid balance sheet classifications
- More freedom in terminology selection
Though private companies still must comply with core ASC standards, they are exempt from many SEC-specific requirements, making the transition potentially easier for professionals working with private entities.
Similarly, while public companies typically classify income statement expenses by function (cost of sales, selling expenses, etc.) rather than by nature (depreciation, employee benefits, etc.), US GAAP actually permits both approaches for all companies.
Functional classification is more common in practice, but natural classification remains an acceptable alternative when it provides more relevant information to financial statement users. Even the descriptions of line items show differences in convention.
While under Ind AS, you might use the term “Revenue from Operations,” under US GAAP, you will typically just see “Revenue” or “Net Sales,” though again, private companies have more flexibility in their terminology.
Other comprehensive income (OCI) treatment:
Let me explain another key difference with a simple example.
When Priya was preparing financial statements for her company’s US parent, she was confused about how to handle OCI.
Under IFRS, you can present OCI as part of your income statement or as a separate statement. Under US GAAP, companies have flexibility too – they may present OCI either in a single continuous statement (starting with net income and adding OCI items) or in two separate statements (one for net income, one for comprehensive income).
The single-statement approach is common in practice, but both are permitted. This differs from the treatment of reclassification adjustments (items moving from OCI to profit or loss), which requires additional disclosures under US GAAP that Priya was not used to preparing.
The first time you tackle US GAAP financial statements, expect it to take much longer than you are used to.
When I helped an Indian tech company prepare their first US GAAP statements, what normally took 2 weeks under Ind AS stretched into 6 weeks as we grappled with the different requirements.
As Priya told me while working through her first US GAAP financial statements, “I kept wanting to reorganise things to make them more logical from an Indian perspective. But I eventually realised there is a method to their structure – it is designed for comparison across companies, not customisation for each business.“
Revenue recognition – same model, different application
Let us talk about something that impacts every company, and that is revenue recognition.
This is where many Indian finance professionals get caught off guard when transitioning to US GAAP.
On the surface, both systems look identical. Both US GAAP (ASC 606) and Ind AS 115/IFRS 15 follow the same five-step model:
- Identify the contract
- Identify performance obligations
- Determine transaction price
- Allocate transaction price
- Recognise revenue
So what is the problem? Despite using the same framework, the application can be worlds apart.
Let me explain the key differences you will encounter:
Contract modifications:
In your Indian accounting experience, when a contract changes, you probably apply general principles to determine how to account for it. Maybe you ask, “Does this change the nature of what we are delivering?” and use your professional judgment.
Under US GAAP, you will find detailed, prescriptive guidance with specific scenarios.
For instance, if you are working for an IT services company that modified a contract to add additional services. Under Ind AS, you would treat it as a continuation of the original contract based on your judgment. Under US GAAP, you would follow a specific decision tree in ASC 606 that will lead you to account for it as a separate contract, a completely different outcome.
The timing of approval also matters more under US GAAP. While Ind AS focuses on when the substance of the agreement is reached, US GAAP often requires formal approval before accounting for the modification.
Variable consideration:
Here is another area where subtle differences between the systems can lead to significantly different outcomes.
Both systems require you to estimate variable amounts like bonuses, penalties, or volume discounts. However, the constraint mechanisms differ in important ways.
Let me clarify with an example: If your company has performance bonuses in contracts, both Ind AS 115 and ASC 606 require that variable consideration (e.g., bonuses, penalties) be included in the transaction price only if it is ‘highly probable’ that a significant revenue reversal will not occur.
While the application may vary slightly due to US GAAP’s more prescriptive guidance, the core threshold is the same.
The methods for estimating variable consideration are also more specifically prescribed under US GAAP, with detailed guidance on applying the “expected value” or “most likely amount” approaches, rather than allowing for broader statistical approaches you might use under Ind AS.
Principal vs agent determinations:
This is a critical area for many Indian IT and service companies. Are you providing the service yourself (principal) or arranging for someone else to provide it (agent)?
The answer determines whether you show revenue gross or net.
Both Ind AS 115 and ASC 606 focus on ‘control’ for principal vs. agent determinations and include specific indicators (like primary responsibility, inventory risk, and pricing discretion).
However, US GAAP provides more detailed application guidance and examples, which may lead to a more structured analysis compared to the broader judgment often applied under Ind AS.
If your company is reselling third-party software with your services, US GAAP would guide you through a more detailed analysis of control indicators rather than allowing the holistic assessment you might make under Ind AS.
Let me share a practical example that might sound familiar: A telecom company offers handsets with service plans – a common bundle. Under Ind AS, you would allocate revenue based on relative standalone selling prices using broad principles and your professional judgment.
Under US GAAP?
You would find yourself navigating detailed guidance on material rights (those discounts for future purchases), significant financing components (when customers effectively pay over time), and specific allocation methods. What seemed straightforward under Ind AS would become a complex technical analysis under US GAAP.
The result would be different revenue timing, different amounts allocated to each component, and ultimately, different financial results – all using the “same” standard.
This is what I mean when I say US GAAP requires rewiring how you think about financial reporting.
Leases – the classification complexity
After understanding revenue recognition, you will need to tackle another challenging area, i.e., lease accounting. Here is what you need to know.
When IFRS 16 and Ind AS 116 introduced a single lessee model, global accounting seemed to be simplifying. But US GAAP took a different approach.
Lessee accounting differences:
Yes, both systems require most leases to be on your balance sheet. But classification still matters significantly under US GAAP.
If you are accounting for a lease under US GAAP, you will need to apply tests to determine if it is
- an operating lease or
- a finance lease.
This classification affects your expense pattern – straight-line for operating leases versus front-loaded for finance leases.
Lessor accounting differences:
If you are a lessor, the differences between US GAAP and IFRS/Ind AS lease accounting are significant.
Under US GAAP (ASC 842), lessors classify leases as operating, sales-type, or direct financing leases, based on whether the lease transfers control of the underlying asset and other criteria, such as collectibility of payments.
Under IFRS 16 and Ind AS 116, lessors classify leases as either operating or finance leases, with finance leases transferring substantially all risks and rewards of ownership. This distinct classification approach creates notable differences in profit recognition timing.
For example, consider a manufacturer leasing equipment with a purchase option reasonably certain to be exercised. Under US GAAP, this may qualify as a sales-type lease, allowing the lessor to recognise profit at lease commencement if control transfers, the fair value differs from the carrying amount, and payments are probable.
Under Ind AS, the same lease would likely be a finance lease; if the lessor is a manufacturer, profit is recognised upfront, but for non-manufacturer lessors, profit is recognised over time through interest income using the effective interest method.
Practical impact:
When you apply these standards, you will find that US GAAP requires more detailed analysis:
- Your discount rate options are different
- You will assess lease terms using more specific criteria
- Your treatment of variable payments follows stricter rules
If you have spent years mastering Ind AS lease accounting, you might find yourself starting almost from scratch with US GAAP. As Priya told me, “Eight years of IFRS knowledge seemed almost useless when I had to learn US GAAP lease accounting.“
Asset impairment – no second chances
Let us talk about one of the starkest philosophical differences between the systems: how to handle assets that lose value.
Think of this as the accounting equivalent of whether people can change. IFRS believes in second chances. US GAAP does not.
The IFRS/Ind AS approach:
When your assets lose value under Ind AS, here is your process:
- Compare carrying amount to recoverable amount (higher of fair value less costs to sell and value in use)
- Recognise impairment if the carrying amount exceeds the recoverable amount
- If circumstances improve later, you can reverse the impairment (except for goodwill)
The US GAAP approach:
Under US GAAP, the process differs based on asset type:
- For long-lived assets (ASC 360): First, compare the carrying amount to the undiscounted future cash flows. If impaired, measure loss as the difference between the carrying amount and fair value.
- For indefinite-lived intangibles and goodwill (ASC 350): Apply fair value-based tests, comparing the carrying amount directly to fair value.
- Impairment reversal? Never allowed for any assets, regardless of type.
This creates a fundamental difference in mindset. US GAAP’s message is clear: once value is lost, it is lost forever. No optimistic reversals allowed.
Real-world impact:
Imagine you run a manufacturing company that wrote down equipment during COVID when demand dropped. As the business recovers:
Under Ind AS, you could reverse that impairment, bringing the asset back to its appropriate value.
Under US GAAP?
That write-down is permanent, affecting your depreciation expense and any future gains if you sell the equipment. The initial conservative decision has permanent consequences.
This one difference can significantly impact how management approaches potential impairment scenarios. Under US GAAP, they might be more reluctant to recognise impairments, knowing there is no way back.
Your transformation roadmap – becoming US GAAP fluent
The gap between Ind AS and US GAAP expertise is not insurmountable.
With focused effort, you can bridge it in 8-12 weeks, though this timeline assumes dedicated study time and access to resources like the FASB Codification.
Depending on your experience level, work commitments, and prior exposure to US reporting, you may need additional time, particularly for complex areas like SEC reporting and industry-specific guidance.

The mindset transformation
Beyond technical knowledge, success requires adapting your thinking:
From judgment to compliance:
- Embrace the structure that US GAAP provides
- Find comfort in detailed guidance
- Appreciate reduced ambiguity
From flexibility to standardisation:
- Accept prescribed formats
- Value comparability over customisation
- Recognise the benefits of uniformity
From principles to rules:
- Develop a checklist mentality
- Master decision trees and flowcharts
- Document rule references, not just conclusions
Priya summarised it perfectly: “In India, we ask ‘what is the economic substance?‘ In the US, they ask, ‘What does the standard say?‘ Both have merit – you just need to know which hat to wear.“
Common challenges and solutions
Based on a number of transitions I have observed, here are the typical stumbling blocks:
Challenge 1: Over-applying judgment
- Indian professionals often seek the “right” answer through analysis
- US GAAP usually prescribes the answer
- Solution: Check codification before applying judgment
Challenge 2: Resistance to “cookbook” approach
- IFRS-trained minds may feel constrained
- Rules seem to override substance
- Solution: Understand rules often codify collective judgment
Challenge 3: Documentation differences
- US GAAP requires specific references
- Indian practice emphasises reasoning
- Solution: Cite ASC paragraphs, not general principles
Challenge 4: Pace of change
- US GAAP updates frequently
- Keeping current feels overwhelming
- Solution: Focus on standards relevant to your industry
Resources for continuous learning
