Objectives of a Tax Audit Under Section 44AB

A key purpose of an income tax audit section 44AB is to maintain transparent and reliable financial reporting. [1]

• Ensure accuracy of income and expenditure: The audit checks whether income and expenses are recorded correctly and supported by appropriate documentation. It ensures figures match the books, prevents misstatements, and confirms that financial details reflect the business's genuine performance during the financial year.
• Verify deductions and compliance: Auditors review deductions, allowances, and claims to ensure they comply with the Income Tax Act and are supported by evidence. This prevents incorrect claims, confirms compliance with legal provisions, and helps maintain clean, regulation-aligned financial reporting without contradictions or unsupported tax benefits.
• Standardize reporting: The audit encourages uniform accounting practices and creates a structured format that simplifies assessment for both taxpayers and the Income Tax Department.
• Prevent tax evasion: By examining accounts in detail, the audit helps identify discrepancies, unreported income, or unusual entries. 

Forms Used in Tax Audit (Form 3CA, 3CB & 3CD)

A 44ab tax audit requires the auditor to issue the main report in either Form 3CA or Form 3CB, while detailed financial disclosures are submitted in Form 3CD. The applicable form depends on whether the taxpayer’s accounts are already audited under any other law. [2] [3]

Form 3CA

Issued when the taxpayer’s accounts are already audited under another law, such as the Companies Act. The tax auditor refers to the existing statutory audit report and then certifies additional tax-specific findings under Section 44AB, ensuring that the accounts, disclosures, and compliance details meet income-tax reporting requirements accurately and transparently.

Form 3CB

Issued when the taxpayer’s accounts are not required to be audited under any other law. In this case, the tax auditor conducts the complete audit solely for income-tax purposes and certifies that the financial statements present an accurate and fair view and comply with all compliance standards prescribed under Section 44AB for the applicable financial year.

Form 3CD

Form 3CD is a detailed statement of particulars filed along with Form 3CA or 3CB. It includes item-wise disclosures on income, expenses, TDS compliance, deductions, related-party transactions, depreciation, loans, and payments. These specifics help the Income Tax Department verify accuracy, identify discrepancies, and assess whether the taxpayer has complied with reporting obligations under Section 44AB.

How Tax Audit Under Section 44AB Is Conducted?

A tax audit under section 44ab follows a structured review by a Chartered Accountant to confirm the accuracy of financial records, verify compliance, and prepare all required disclosures before filing with the Income Tax Department. [1]

• Appointment of a Chartered Accountant: A qualified Chartered Accountant is formally appointed to conduct the audit, review financial data, and ensure every part of the process follows statutory guidelines, professional standards, and the detailed requirements outlined under Section 44AB.
• Verification of Books & Statements: The auditor examines books of account, ledgers, invoices, vouchers, and bank statements to ensure that every transaction is correctly entered, documented, and traceable, helping confirm that financial records match the taxpayer’s actual business activities.
• Review of Deductions, Loans & Cash: The auditor reviews deductions, loans, capital transactions, and cash transactions to confirm compliance with legal provisions, documentation requirements, and monetary limits, ensuring accuracy and preventing irregularities or unsupported claims in the tax computation.
• Preparation of Form 3CD: The auditor prepares Form 3CD by documenting detailed particulars related to income, expenses, statutory payments, TDS, depreciation and other financial elements required for a complete and transparent tax assessment under Section 44AB.
• Uploading the Audit Report: Once all checks are completed, the auditor uploads Form 3CA or Form 3CB along with Form 3CD on the Income Tax e-filing portal, completing the reporting process for the taxpayer’s audit submission.

Due Date and Penalties of Non-Compliance

Under Section 44AB of the Income Tax Act, taxpayers must submit their tax audit report within the prescribed deadline to avoid penalties. This ensures timely compliance, accurate reporting and smoother processing of returns for both businesses and professionals. [1]

• Tax Audit Due Date: For most taxpayers covered by Section 44AB, the audit report must be filed by 31st October of the assessment year. Timely filing ensures complete disclosures, avoids assessment delays and reduces the risk of errors that commonly arise when submissions are rushed at the last moment.
• Penalty for Non-Compliance (Section 271B): Failure to submit the audit report on time attracts a penalty under Section 271B of 0.5 percent of turnover, capped at ₹1,50,000. This penalty encourages timely compliance, though it may be waived if the taxpayer proves reasonable cause for the delay.

Exemptions from Tax Audit Under Section 44AB

Under 44AB of the Income Tax Act, certain taxpayers are exempt from a tax audit if their turnover or gross receipts fall below the specified limits or if they qualify for presumptive taxation without declaring a lower income. [1]

• Presumptive Scheme (Section 44AD): Exempt when turnover is up to ₹2 crore and the taxpayer declares income at the prescribed presumptive rate without opting to declare a lower taxable profit.
• Presumptive Scheme (Section 44ADA): Professionals with gross receipts up to ₹50 lakh are exempt if they declare income at the presumptive rate instead of disclosing lower profits under normal computation rules.
• Presumptive Scheme (Section 44AE): Transport operators using Section 44AE are exempt if they declare income based on the fixed per-vehicle presumptive system and do not report income below the required limit.
• Small Businesses Below Threshold: Businesses with turnover below ₹1 crore, or below ₹10 crore when cash transactions are within 5%, are exempt since they do not cross the mandatory audit limits.
• Small Professionals Below Limit: Professionals whose gross receipts do not exceed ₹50 lakh remain exempt because they fall below the audit applicability threshold as defined under Section 44AB provisions.
