What Is a Tax Audit in India?

Meaning and Purpose of Tax Audit

A tax audit is an examination of accounts and prescribed tax particulars under income-tax legislation. Its purpose is to support accurate reporting of income, deductions, expenses and other information required under the applicable tax audit provisions.

For Financial Year 2025–26, tax audit requirements are governed principally by Section 44AB of the Income-tax Act, 1961. The Income-tax Act, 2025 introduces a revised statutory framework for subsequent tax years.

Objectives of Tax Audit Services

Tax audit procedures and supporting preparation help businesses identify inconsistencies in accounting records, examine tax-sensitive transactions, review statutory liabilities and prepare the information required for prescribed tax reporting.

A tax audit is not a guarantee that the tax authorities will accept every claim or that an assessment cannot subsequently be initiated.

Difference Between Tax Audit and Financial Statement Audit

A statutory financial statement audit and an income-tax audit serve different purposes. A statutory audit examines financial statements under the applicable governing law, while a tax audit addresses prescribed income-tax reporting requirements.

A company may require both engagements. Read our guide to Statutory Audit Services in India.

Tax Audit Applicability Under Section 44AB

Tax Audit Turnover Limit for Businesses

For Financial Year 2025–26, a person carrying on business is generally required to obtain a tax audit where total sales, turnover or gross receipts exceed ₹1 crore, subject to the enhanced threshold and other applicable statutory provisions.

The computation of turnover should reflect the nature of the business and applicable accounting and professional guidance. Special consideration may be required for commission agents, derivatives transactions, reimbursements and other transactions where gross receipts do not necessarily represent ordinary sales.

Enhanced Tax Audit Threshold of ₹10 Crore

The business turnover threshold may increase from ₹1 crore to ₹10 crore where aggregate cash receipts do not exceed 5% of aggregate receipts and aggregate cash payments do not exceed 5% of aggregate payments during the relevant previous year.

Both conditions must be satisfied independently. Non-account-payee cheques and bank drafts are treated as cash for the prescribed test.

Businesses should maintain appropriate reconciliations of cash and non-cash receipts and payments to substantiate eligibility for the enhanced threshold.

Tax Audit Limit for Professionals

For Financial Year 2025–26, a person carrying on profession is generally required to obtain a tax audit when gross receipts exceed ₹50 lakh, subject to the applicable provisions.

The separate ₹75 lakh eligibility ceiling available under Section 44ADA in specified circumstances relates to presumptive taxation and should not be treated as a general replacement for the Section 44AB professional audit threshold.

Tax Audit Under Presumptive Taxation Provisions

Tax Audit Under Section 44AD

Section 44AD provides a presumptive taxation scheme for eligible businesses and taxpayers. The applicable conditions depend on eligibility, turnover, prescribed presumptive income and the taxpayer’s previous use of the scheme.

Where the statutory opt-out provisions apply, a taxpayer may be required to maintain books and obtain a tax audit if the relevant income conditions are satisfied.

Declaring profits below the prescribed presumptive percentage does not automatically establish tax audit liability in every situation. The complete statutory conditions must be evaluated.

Tax Audit Under Section 44ADA

Section 44ADA provides a presumptive taxation framework for specified eligible professionals.

For Financial Year 2025–26, the normal gross-receipts eligibility ceiling is ₹50 lakh, with an enhanced ceiling of ₹75 lakh where the prescribed cash-receipt condition is satisfied.

An eligible professional declaring income below the prescribed presumptive amount must evaluate the specific books-of-account and tax audit conditions, including the applicable income threshold.

Tax Audit Under Section 44AE and Other Presumptive Schemes

Section 44AE applies to eligible businesses engaged in plying, hiring or leasing goods carriages. Other presumptive provisions may apply to specified business activities.

Tax audit applicability under these provisions depends on the particular statutory conditions. Businesses should not apply the ordinary turnover threshold without considering the relevant presumptive taxation provisions.

Tax Audit Requirements for Different Business Entities

Tax Audit for Private Limited and Public Limited Companies

Companies must evaluate tax audit applicability separately from their statutory audit obligations.

An Indian company may be required to obtain a statutory audit under the Companies Act, 2013 even when a tax audit under Section 44AB is not applicable.

Newly incorporated companies can review our Company Registration Services in India for incorporation and initial regulatory compliance.

Tax Audit for LLPs and Partnership Firms

Limited Liability Partnerships and partnership firms should evaluate tax audit applicability based on their business activities, turnover, gross receipts and relevant presumptive taxation provisions.

Partnership firms may also require specific consideration of partner remuneration, interest, capital accounts and other transactions relevant to income-tax reporting.

Tax Audit for Proprietorships and Professionals

Proprietorship businesses and professionals should examine turnover or gross receipts, applicable presumptive taxation provisions, books-of-account requirements and tax audit reporting obligations.

Professional service providers should also review receipts reported through invoices, bank statements, TDS records and the Annual Information Statement.

Tax Audit Forms: Form 3CA, Form 3CB and Form 3CD

Form 3CA for Accounts Audited Under Another Law

For Financial Year 2025–26, Form 3CA is generally applicable where the taxpayer’s accounts are required to be audited under another law and a tax audit under Section 44AB is also applicable.

Form 3CA is accompanied by Form 3CD containing the prescribed tax audit particulars.

Form 3CB for Other Tax Audit Cases

Form 3CB is generally applicable where the taxpayer is required to obtain a tax audit but the accounts are not required to be audited under another law.

The applicable audit report is accompanied by Form 3CD. Selection between Form 3CA and Form 3CB depends on the statutory audit requirements applicable to the taxpayer.

Form 3CD and Clause-wise Tax Audit Reporting

Form 3CD contains prescribed particulars relating to accounting methods, depreciation, tax deductions, inadmissible expenditure, statutory dues, TDS and TCS, specified loans and deposits, and other matters.

Accurate Form 3CD preparation requires reconciliations between financial statements, accounting records, tax computations and supporting documents.

For official guidance, refer to the Income Tax Department e-Filing Portal.

Tax Audit Due Dates and Income-tax Law Changes

Tax Audit for FY 2025–26 and AY 2026–27

Tax audits relating to Financial Year 2025–26 and Assessment Year 2026–27 are governed by the relevant provisions of the Income-tax Act, 1961.

The applicable tax audit reporting forms for this period are Form 3CA or Form 3CB, as appropriate, together with Form 3CD.

Businesses should determine their applicable audit-report filing date based on their reporting category and any CBDT extension.

Tax Audit Under the Income-tax Act, 2025

The Income-tax Act, 2025 applies from Tax Year 2026–27 and introduces a revised legislative framework for tax audit compliance.

Section 63 addresses tax audit requirements under the new framework, while Form No. 26 is prescribed for the relevant tax audit reporting under the Income-tax Rules, 2026.

Taxpayers should use the forms and provisions applicable to the relevant financial year or tax year rather than applying the earlier reporting format automatically to subsequent periods.

Tax Audit Report Filing Deadlines and Extensions

The applicable audit-report due date depends on the relevant assessment year or tax year, taxpayer category and any applicable CBDT notification or circular.

For AY 2026–27, CBDT extended the tax audit-report filing deadline for the specified non-transfer-pricing category to 21 October 2026. Other categories, including transfer-pricing cases, may have different deadlines.

Before filing, taxpayers should verify the current position through the official Income Tax Department portal.

Scope of Tax Audit Services in India

Review of Books of Account and Accounting Policies

Tax audit preparation involves reviewing the trial balance, general ledger, journal entries, accounting policies, financial statements and relevant supporting schedules.

Particular attention is given to unusual transactions, material accounting adjustments, year-end provisions and differences between accounting and tax treatment.

Depreciation and Tax Deduction Review

Tax depreciation may differ from depreciation recognised in financial statements.

Businesses should reconcile fixed asset additions, disposals, depreciation blocks and other adjustments relevant to income-tax computation.

Expenses subject to specific deduction restrictions or payment conditions should also be separately identified.

Related-party Transactions and Specified Payments

Transactions involving related parties, specified persons, partners and associated enterprises may require additional tax audit disclosures or supporting documentation.

Relevant records may include agreements, invoices, loan schedules, interest calculations, partner remuneration workings and transaction reconciliations.

GST, TDS and Financial Reconciliations for Tax Audit

GST Turnover Reconciliation

Businesses should reconcile revenue reported in financial statements with GSTR-1, GSTR-3B and other relevant GST records.

Differences may arise from credit notes, advances, exports, timing adjustments, exempt supplies and other classification matters.

GST turnover and income-tax turnover are not necessarily identical. Each difference should be explained and supported.

Explore our GST and Indirect Tax Services for assistance with GST compliance and reconciliations.

TDS, TCS and Statutory Liability Reconciliation

Tax audit preparation includes reconciling TDS and TCS returns, challans, expense ledgers and relevant tax-credit records.

Businesses should separately review statutory liabilities such as PF, ESI, GST and other payments where deduction timing or reporting obligations may arise.

Employee contributions to welfare funds require particular attention because the applicable income-tax deduction rules differ from those governing employer contributions.

AIS, Form 26AS and Income-tax Return Reconciliation

The Annual Information Statement, Form 26AS and other tax information should be compared with accounting records and the proposed income-tax return.

Unexplained differences involving interest, receipts, TDS credits or other transactions should be investigated before finalising the tax computation.

Tax Audit for Foreign-Owned Indian Subsidiaries

Tax Audit Requirements for Indian Subsidiaries

An Indian subsidiary of a foreign company must evaluate its tax audit requirements under Indian income-tax legislation.

Foreign ownership does not automatically exempt an Indian company from statutory audit, tax audit or other applicable Indian regulatory obligations.

Foreign investors establishing Indian operations can explore our India Market Entry Consulting Services and Wholly Owned Subsidiary Registration in India.

Intercompany Payments and International Transactions

Foreign-owned companies may have management charges, royalties, technical service fees, software payments, reimbursements, intercompany loans and other cross-border transactions.

These transactions should be supported by appropriate agreements, invoices, accounting records and withholding-tax analysis.

Our team assists with reconciliation and coordination of international tax matters relevant to the tax audit process.

Transfer Pricing and Form 3CEB Coordination

Where an Indian company enters into reportable international transactions or specified domestic transactions, separate transfer-pricing compliance requirements may arise.

For FY 2025–26, Form 3CEB reporting under Section 92E is distinct from the tax audit requirements under Section 44AB.

Relevant information should be reconciled across financial statements, Form 3CD, transfer-pricing records and Form 3CEB, where applicable.

Difference Between Tax Audit, Statutory Audit and Internal Audit

Tax Audit Versus Statutory Audit

A tax audit addresses income-tax reporting requirements, whereas a statutory financial statement audit examines the financial statements under the applicable governing legislation.

Both may apply to the same business, depending on the entity and statutory conditions.

Tax Audit Versus Internal Audit

Internal audit evaluates business processes, internal controls, risk management and operational compliance.

Internal audit does not replace tax audit or statutory audit requirements.

Learn more about our Internal Audit Services in India.

Our Tax Audit Service Process

Initial Applicability Assessment

We begin by reviewing the entity’s business activities, turnover, gross receipts, cash transaction percentages, presumptive taxation position and relevant reporting requirements.

This helps identify the applicable tax audit provisions and documentation requirements.

Preparation of Tax Audit Schedules

Our team assists with accounting reconciliations, Form 3CD information schedules, supporting documents and management explanations.

Potential reporting inconsistencies are identified and discussed with management before the independent auditor completes the engagement.

Independent Audit Reporting and Filing

The eligible practising Chartered Accountant or CA firm responsible for the tax audit independently evaluates the evidence, performs the required procedures and issues the applicable audit report.

The report is submitted through the prescribed income-tax filing process and is subject to the applicable taxpayer acceptance requirements.

Common Issues Identified During Tax Audit

Turnover and Accounting Reconciliation Differences

Differences between sales registers, financial statements, GST returns and banking records can create reporting difficulties.

Early reconciliation helps businesses identify timing differences, classification errors and transactions requiring further explanation.

Tax Deduction and Statutory Compliance Issues

Common areas requiring attention include TDS defaults, delayed statutory payments, inadmissible expenditure, related-party transactions, depreciation differences and incomplete supporting records.

Appropriate documentation and timely corrective action can reduce avoidable compliance difficulties.

Tax Audit Fees in India

Factors Affecting Tax Audit Professional Fees

Tax audit fees depend on the nature of the business, turnover, transaction volume, number of locations, accounting quality, reporting complexity and professional effort involved.

Companies with multiple locations, substantial intercompany transactions or complex accounting arrangements may require additional audit procedures and supporting schedules.

Scope of Tax Audit and Compliance Assistance

Engagement proposals should clearly distinguish accounting preparation, tax audit readiness, compliance advisory, reporting coordination and independent audit certification.

EzyBiz India provides the agreed advisory and coordination services, while independent audit and certification responsibilities remain with the eligible appointed practising Chartered Accountant or CA firm.

Penalty for Non-compliance With Tax Audit Requirements

Penalty Under Section 271B

For applicable defaults under the Income-tax Act, 1961, Section 271B provides for a penalty equal to the lower of 0.5% of total sales, turnover or gross receipts and ₹1,50,000, subject to the relevant statutory provisions.

Penalty consequences should be evaluated according to the nature of the default and the law applicable to the relevant period.

Reasonable Cause and Penalty Relief

Section 273B provides relief from specified penalties where the taxpayer establishes reasonable cause for the relevant failure.

Businesses should preserve documentary evidence explaining delays, take timely corrective action and respond appropriately to notices issued by the Income Tax Department.

Frequently Asked Questions About Tax Audit in India

Is tax audit compulsory for every private limited company?

No. A private limited company is generally required to undergo statutory financial statement audit, but tax audit applicability is separately determined under the relevant income-tax provisions.

What is the tax audit turnover limit in India?

For FY 2025–26, the general business threshold is ₹1 crore, potentially increasing to ₹10 crore where the prescribed cash receipts and cash payments conditions are satisfied. The general professional gross-receipts threshold is ₹50 lakh, subject to other applicable provisions.

Can the same Chartered Accountant conduct statutory and tax audits?

An eligible practising Chartered Accountant or CA firm may undertake both engagements, subject to applicable appointment, eligibility, independence and professional requirements.

Is Form 3CD the same as an income-tax return?

No. Form 3CD contains prescribed tax audit particulars. The income-tax return is a separate filing, and relevant information should be reconciled between the two.
