Financial Due Diligence in India: What It Covers and When Businesses Need It

TL;DR Summary

Due diligence is not an audit; it looks forward and assesses risks. Common in M&A, private equity, IPO, and joint ventures. Scope covers financials, tax, debt, controls, and related-party transactions. Red flags include weak earnings quality, hidden liabilities, and tax issues. A CA firm structures the review, analyses data, and quantifies risks. PKC  provides end-to-end due diligence with regulatory depth.

Financial due diligence is a forward-looking review of a target company’s true financial health – verifying earnings, debt, tax exposure, and controls before a transaction closes, not just checking past compliance like an audit does. In India, it’s required for M&A, private equity investment, joint ventures, and large debt financing, and typically takes 4 to 10 weeks depending on deal complexity.

Due diligence services in India are now a standard requirement across M&A transactions, private equity investments, and business acquisitions. Getting it right before a transaction protects your investment, uncovers potential liabilities, and strengthens your negotiating position.

Explore with us what financial due diligence involves, when it is required, what gets reviewed, common red flags, and how it differs from an audit. Also understand what to expect in a due diligence engagement with an experienced CA firm like PKC Management Consulting. 

What Is Financial Due Diligence?

Financial due diligence is a structured investigation of a target company’s financial health before you enter into a significant transaction. The goal is to confirm that what the seller is claiming about revenues, profits, assets, and liabilities is actually true.

A proper financial due diligence review  involves examining financial statements, accounting records, tax positions, and internal controls to verify that the business is what it claims to be. 

Scope of due diligence includes:

• Audited financial statements: balance sheets, profit and loss accounts, and cash flow statements for the last three to five years
• Auditor correspondence and management letters: these reveal weaknesses the auditors flagged
• Debt schedules: both domestic and international borrowings
• Accounts receivable and payable: who owes the company money and whom it owes
• Tax positions and potential liabilities: income tax, GST, transfer pricing issues
• Quality of earnings: whether reported profits are sustainable or inflated by one-time items
• Cash flow reliability: if cash flows are consistent with reported profits, or are there growing gaps
• Working capital adequacy: if the business is funded well enough to sustain operations post-acquisition
• Internal control systems: how reliable is the financial reporting process
• Related-party transactions: loans to group companies, personal expenses run through the business

Financial due diligence is often considered the most critical stream because it reveals the financial implications of findings from legal, tax, and operational reviews.

After India’s 1991 economic liberalisation, the practice gained traction, driven largely by foreign investors and their advisors. Today, it’s a standard practice across mergers, acquisitions, private equity investments, and venture capital funding.

Financial due diligence is mostly carried out by chartered accountants (CAs) or transaction advisory teams with dedicated M&A due diligence expertise, since the review requires understanding both accounting standards and the regulatory knowledge.

The output is a financial due diligence report that is presented to the buyer or investor before they decide to proceed, renegotiate, or walk away from a deal.

When Is Due Diligence Required?

Due diligence  isn’t always legally mandated and isn’t just limited to large corporate mergers. There are several situations where it becomes necessary:

Mergers and Acquisitions

This is the most common scenario. Whether you’re buying a company or selling one, due diligence is necessary for both sides. Buyers use it to uncover hidden liabilities and verify valuations. Sellers use it to prepare for investor scrutiny and address issues before they can become deal breakers.

For cross-border acquisitions, the stakes are higher. India’s regulations including the Ministry of Corporate Affairs, RBI, SEBI, and the GST Council, makes compliance critical. Due diligence helps foreign companies identify risks before investing.

Private Equity and Venture Capital Investment

If you’re an investor putting money into an Indian company, financial due diligence is required  before a term sheet converts into a funding agreement.

 Investors want to ensure their capital is going into a transparent, financially sound business. For startups seeking funding, a clean due diligence report builds credibility and signals that the business follows proper accounting practices

Joint Ventures and Strategic Alliances

When two companies form a partnership, each needs to know the other’s financial reality. Due diligence reveals whether a potential partner has hidden debts, tax disputes, or unsustainable cash flow. 

It’s also crucial when foreign companies want to perform background checks on Indian partners or suppliers and need to understand the compliance standing of the Indian entity.

Corporate Restructuring and Distressed Asset Sales

When a company is being reorganised , even within the same group, due diligence helps the new management team understand what they’re taking over. 

In distressed M&A, asset diligence must be more comprehensive, particularly on title, encumbrances, and release of interests.

Lending and Project Finance

Banks and NBFCs increasingly require financial due diligence when a company is seeking large-ticket project funding or structured debt, particularly for infrastructure and manufacturing projects.

They need to verify that the borrower’s financial position supports the debt and that there are no undisclosed liabilities that could impair repayment.

Inbound Foreign Investment 

This is another major trigger. 

When a foreign company is considering an investment into an Indian entity, it must evaluate the target’s compliance with FEMA, RBI regulations, and sector-specific foreign investment caps in addition to the financial review.

Scope: What Gets Reviewed

Like any other financial services engagement, the scope of a due diligence review varies. 

It is based on the deal size, the sector you’re operating in, the transaction structure, and your risk appetite as a buyer or investor. 

But in most cases, the review covers the same core areas: 

Area	What Gets Reviewed
Financial Statements & Audit Reports	Accuracy, consistency, audit qualifications
Quality of Earnings	EBITDA normalisation, one-time gains, recurring profitability
Debt & Liabilities	Loans, covenants, contingent liabilities, off-balance-sheet obligations
Revenue & Gross Margins	Revenue recognition, customer concentration, contract terms, margin trends
Cost Structure & EBITDA Normalisation	Operating costs, non-recurring expenses, owner compensation, EBITDA adjustments
Accounts Receivable & Payable	Receivable ageing, payable ageing, collection efficiency, supplier payments
Internal Controls & Information Systems	Internal controls, approvals, segregation of duties, fraud risk
Related-Party Transactions	Promoter dealings, group company transactions, arm’s-length pricing
Projections & Budgets	Financial forecasts, capital budgets, forecasting accuracy
Working Capital Analysis	Working capital trends, cash requirements, purchase price adjustments
Tax Compliance	Income tax, GST, TDS, tax notices, contingent liabilities
Legal & Regulatory Compliance	Licences, contracts, corporate records, litigation, statutory compliance
Off-Balance-Sheet Items	Guarantees, contingent liabilities, deferred obligations, undisclosed commitments

Financial Statements and Audit Reports

Your due diligence team will examine audited financial statements such as balance sheets, profit and loss accounts, and cash flow statements, usually for the last 3-5 years.  

They’ll also review quarterly statements, auditor’s reports, and any correspondence between the auditors and management. This correspondence often reveals weaknesses the auditors flagged that never made it into the final report. 

Quality of Earnings

This is one the most important parts of financial due diligence. The team analyses whether the company’s reported profits are sustainable or inflated by one-time gains. 

They’ll normalise EBITDA by stripping out non-recurring income, related-party transactions, and exceptional expenses. For example, if a company sold a piece of real estate and booked a large profit, that’s not repeatable income. 

Adjusting for these items gives you a clearer picture of what the business actually earns year after year

Debt and Liabilities

The review includes both on-balance sheet debt and off-balance sheet liabilities. The due diligence experts will scrutinise outstanding loans, security documents, charges registered with the Registrar of Companies, and any defaults under financial agreements. 

They’ll also take a look at unrecorded liabilities, such as pending litigation provisions, unfunded gratuity, and capital commitments that haven’t been booked yet.

Revenue and Gross Margins

Revenue is one of the most scrutinised areas. 

The review checks customer concentration (how much of revenue comes from one or two clients), contract terms, renewal rates, and whether revenues are recognised correctly under applicable accounting standards.

Cost Structure and EBITDA Normalisation

Costs are analysed to separate operating expenses from non-recurring items. 

Owner compensation, related-party transactions, and extraordinary expenses are examined to arrive at a normalised EBITDA, the figure buyers and investors actually base valuations on.

Accounts Receivable and Payable

They will review the ageing of receivables and payables. Old receivables that aren’t being collected signal poor credit management or customers who can’t pay. 

Similarly, delayed payables might indicate cash flow problems or strained supplier relationships.

Internal Controls and Information Systems

The reliability of financial information depends on the strength of internal controls. Weak controls increase the risk of fraud and errors in financial reporting.

Experts will assess whether the company has documented processes, segregation of duties, and proper authorisation procedures. 

Related-Party Transactions

This is a major focus area in India. In family-owned and promoter-driven Indian businesses, related party transactions are common like loans to promoters, payments to group entities, lease arrangements at non-arm’s-length terms.

Due diligence experts examine loans to group companies, personal expenses run through the business, and any other transactions with related parties. These transactions can hide cash leakage or indicate poor corporate governance.

Projections and Budgets

This involves reviewing the company’s financial projections, capital budgets, and strategic plans.

The due diligence team will compare historical projections with actual performance to assess management’s forecasting ability. Unrealistic projections are a huge red flag.

Working Capital Analysis

Working capital is reviewed across multiple periods to identify the typical level the business requires to operate. This matters because working capital adjustments often form part of the final purchase price.

Buyers need to negotiate a suitable working capital target in the sale agreement to ensure the business has enough funds to operate from the first day after closing.

Tax Compliance

Tax due diligence in India covers direct tax (income tax, TDS compliance, pending assessments, contingent tax liabilities) and indirect tax (GST filings, input tax credit claims, pending notices). 

Pending scrutiny notices or demand orders from the Income Tax Department can become the buyer’s liability post-acquisition.

Legal and Regulatory Compliance

This includes reviewing incorporation documents, shareholder agreements, material contracts, labour law compliance, licences (FSSAI, pollution control, factory, SEBI), and any ongoing litigation. 

For manufacturing businesses, environmental clearances and pollution compliance are critical.

Off-Balance-Sheet Items

Guarantees given to third parties, contingent liabilities, deferred payment obligations, and undisclosed loans do not appear on the face of the balance sheet. 

A thorough review uncovers these before the deal is signed.

Financial Red Flags That Surface in Due Diligence

Some of the most significant deal-breakers and valuation adjustments in Indian transactions are uncovered only during due diligence. 

Here are the red flags that our experts at PKC Management Consulting have frequently discovered: 

Declining Revenue or Profitability

A steady decline in revenue or profits is an early warning sign, but the reasons behind it are more than the numbers. Due diligence determines whether the decline is temporary (market conditions, seasonality, competition) or reflects deeper structural issues. 

For example, stable revenue with falling profits may indicate rising costs, while stable profits despite falling revenue may result from short-term cost-cutting that hides long-term problems.

Poor Quality of Earnings (QoE)

Reported profits do not always represent the company’s true earning capacity.

Common indicators:

• One-time gains from asset sales or extraordinary income inflating profits
• Aggressive revenue recognition before contractual obligations are fulfilled
• Capitalising operating expenses that should have been recognised immediately
• Significant related-party transactions conducted on non-commercial terms
• Heavy dependence on non-recurring income

Revenue Inflation

Artificially inflated revenue is a serious concern, particularly in privately owned and promoter-led businesses. 

Common practices:

• Channel stuffing to boost year-end sales
• Round-tripping through related entities
• Recording sales before delivery or customer acceptance
• Large year-end sales followed by high returns

These practices overstate revenue without generating real cash flow, leading to misleading financial performance and inflated valuations.

Hidden or Undisclosed Liabilities

Not all liabilities appear on the balance sheet. Financial due diligence identifies hidden obligations by reviewing contracts, legal records, tax filings, and other documents.

Examples:

• Pending tax disputes
• Litigation and legal claims
• Employee benefit liabilities
• Corporate guarantees
• Warranty and contractual obligations
• Unrecorded capital expenditure commitments

These liabilities can materially affect enterprise value and future cash flows.

Tax Non-Compliance

Tax compliance remains one of the most significant risk areas in Indian due diligence assignments. 

Even businesses with healthy financial performance can face substantial tax exposures if statutory compliance has been neglected.

Unresolved tax matters may result in penalties, interest, litigation, and future cash outflows that directly affect transaction value.

Weak Internal Controls

Weak internal financial controls increase the risk of fraud, errors, and operational inefficiencies. Although they may not prevent an acquisition, they often require stronger contractual protections.

Common weaknesses:

• Poor segregation of duties
• Undocumented financial processes
• Dependence on a single promoter or finance employee
• Delayed reconciliations
• Weak inventory controls
• Inadequate payment and procurement approvals

These weaknesses often increase the need for post-acquisition financial restructuring.

Related-Party Transactions and Fund Diversion

They are common in family-owned businesses, but excessive or poorly documented transactions deserve careful examination.

Due diligence teams assess:

• Loans or advances to promoters and group entities
• Personal expenses recorded as business expenditure
• Purchases or sales at non-market prices
• Outstanding receivables from related parties with little likelihood of recovery
• Unexplained fund transfers between connected entities

Such transactions may indicate governance concerns, cash leakage, or diversion of company resources that reduce the true economic value of the business.

Working Capital and Liquidity Issues

A deteriorating working capital position may indicate underlying operational stress even if reported profits appear satisfactory.

For example, a business reporting strong profits but consistently negative operating cash flows may face liquidity challenges shortly after the acquisition.

Key areas reviewed:

• Overdue receivables
• Slow-moving or obsolete inventory
• Rising unpaid supplier balances
• Declining inventory turnover
• Gaps between reported profits and operating cash flow

Aggressive Accounting Policies

Although accounting policies may comply with applicable accounting standards, they may still present an overly optimistic picture of financial performance.

Areas requiring closer review:

• Unrealistically low depreciation rates
• Inadequate provisions for doubtful debts
• Insufficient inventory write-downs
• Excessive capitalisation of routine operating expenses
• Revenue recognition practices that differ from industry norms

Inconsistent Financial Information

A lack of consistency across financial records is one of the clearest warning signs during due diligence.

Examples:

• Revenue reported in financial statements differing from GST filings
• Bank statements not supporting reported cash balances
• Inventory records that do not reconcile with accounting books
• Management reports that differ significantly from audited financial statements

These inconsistencies may reflect weak financial reporting systems or, in more serious cases, deliberate misrepresentation.

Qualified Audit Reports

The statutory auditor’s report often provides valuable insight into financial risks. Qualified opinions, adverse opinions, disclaimers, or emphasis of matter paragraphs should always be investigated thoroughly.

Pay special attention to:

• Going concern assumptions
• Related-party transactions
• Asset valuation
• Inventory verification
• Revenue recognition
• Internal financial controls

Regulatory and Statutory Non-Compliance

GST mismatches between GSTR-1 and GSTR-3B filings, TDS defaults, Provident Fund arrears, or pending ROC filings may be manageable individually but together indicate a pattern of compliance negligence.

Financial due diligence extends beyond accounting records to evaluate compliance with applicable laws and regulations.

Due Diligence vs Audit: Key Differences

Many business owners assume due diligence and audit are the same thing. They  aren’t as they serve very different purposes and carry different levels of responsibility.

Here is a breakdown of the key differences:

Aspect	Audit	Due Diligence
Purpose	Express an opinion on financial statements	Evaluate an investment or transaction
Focus	Past financial records	Past, present, and future business performance
Scope	Financial statements only	Financial, tax, legal, operational, commercial
Who requests it	Regulators, shareholders, lenders	Buyers, investors, lenders
Outcome	Audit report with opinion	Due diligence report with findings and recommendations
Timing	Regular intervals (annual, quarterly)	Transaction-specific
Flexibility	Standardised approach	Customised based on deal

An audit is an independent examination of financial statements to express an opinion on whether they present a true and fair view. If it’s a statutory or financial audit you’re looking for rather than a transaction review, PKC’s financial audit services cover that process in detail. It looks backward and verifies that what happened in the past was recorded correctly.

When you get an audit, the auditor follows a standard framework. They issue an opinion and that is where it ends.

Due diligence, on the other hand, is transaction-driven. It is commissioned by a specific party: a buyer, investor, or lender, to serve their specific decision. The scope is negotiated between the client and the CA firm based on what matters most to the transaction.

When you conduct due diligence, the team goes beyond checking numbers. They analyse why the numbers are what they are. They look for hidden liabilities. They assess the sustainability of earnings. They evaluate management’s projections. They identify risks that could affect the deal.

A company can have clean, unqualified audit reports for five years and still have significant issues surface in due diligence. 

In India, it is not uncommon for due diligence to uncover working capital issues, promoter-related transactions, or undisclosed liabilities that were technically disclosed in the notes to accounts but never flagged as material concerns by the statutory auditor. 

This is not necessarily a failure of the audit, it reflects the different purposes these two processes serve.

How a CA Firm Conducts Due Diligence

A CA firm like PKC Management Consulting follows a structured process when conducting financial due diligence. Here is how it works: 

Step 1: Scoping and Engagement Setup

The team starts by understanding the transaction. What are you buying? Why are you buying it? What is the deal structure? What are your key concerns? This shapes the scope of the review.

The team also reviews the information memorandum, if one exists. They identify the key drivers of value and the main risks.

Step 2: Data Request and Virtual Data Room Access

The target company provides access to a virtual data room. This is a secure online repository containing financial statements, tax returns, contracts, and other documents. 

The due diligence team reviews everything, including:

• Audited financial statements for the last three to five years
• Management accounts and board reports
• Tax returns and assessment orders
• Debt schedules and loan agreements
• Customer and supplier contracts
• Employee agreements and benefits
• Related-party transaction details

Step 3: Financial Analysis

Now, the core review begins. The team builds financial models to the company’s true financial performance by reviewing:

• Revenue, costs, and cash flow to assess profitability.
• EBITDA normalisation by removing one-time gains and unusual expenses.
• Working capital cycles to determine the business’s ongoing funding needs.
• Debt and hidden liabilities, including off-balance-sheet obligations.
• Tax compliance (Income Tax, GST, and TDS) and pending disputes.
• Internal controls to identify risks of fraud or financial errors.

Ratios are benchmarked against industry peers. Cash flow statements are reconciled with reported profits. This phase is intensive.

Step 4: Management Interviews & Site Visits (Where Relevant)

The CA team meets with the target company’s CFO, operations head, and key personnel to understand the business model, customer relationships, major cost drivers, and any known risks. 

These conversations often reveal context that documents alone cannot provide.

In case of on ground businesses like manufacturing, retail chains, or real estate holdings, the team may also conduct site visits. These help verify the existence and condition of assets, inventory, and operational infrastructure.

Step 5: Report Preparation

The team prepares a detailed due diligence report. It summarises findings, highlights red flags, and quantifies the impact of identified issues.  Issues are usually rated by significance: material, moderate, or informational.

The report includes:

• Executive summary
• Financial analysis
• Quality of earnings findings
• Debt and liability summary
• Tax compliance status
• Key risks and recommendations
• Valuation implications

Timeline: 

The timeline is usually between 4 to 6 weeks for most engagements in the mid-size space. 

Extended timelines of 10 to 12 weeks or more common for cross-border deals, regulated industries, or transactions requiring antitrust clearance. 

Also, sometimes, deals involving manufacturing businesses with multiple licences and pending tax assessments take longer.

FAQs

What is financial due diligence?

Financial due diligence is a structured review of a target company’s financials, conducted before a transaction closes. It examines the quality of earnings, working capital, debt, tax compliance, and off-balance-sheet risks to give the buyer or investor a verified picture of the business, not just what the seller has presented.

When should a company get due diligence done?

Due diligence should be initiated after a letter of intent or term sheet is signed, but before the final agreement is executed. In India, this applies to mergers, acquisitions, private equity investments, joint ventures, inbound foreign investments, and large-ticket debt financing. Starting early gives sufficient time to address findings and renegotiate terms if needed.

What documents are needed for due diligence?

Core documents include audited financial statements for the last three to five years, income tax returns, GST returns, bank statements, incorporation documents, shareholder agreements, material contracts, licences, and details of pending litigation or tax demands. The exact list is tailored based on the transaction type, sector, and specific risk areas identified during scoping.

How long does financial due diligence take in India?

For M&A transactions in India, due diligence typically takes 4 to 10 weeks or more depending on scope. Smaller transactions or clean businesses with well-maintained records can be completed in 3 to 4 weeks. Complex deals involving multiple entities, pending tax assessments, or regulated industries take longer. The timeline also depends on how quickly the target company provides access to documents.
