Frequently Asked Questions (FAQs)

Essential information about tax audit requirements, procedures, and compliance under Section 44AB of Income Tax Act

A tax audit is a mandatory examination of a taxpayer's financial records by a Chartered Accountant to ensure compliance with income tax laws. Under Section 44AB of the Income Tax Act, certain taxpayers must get their accounts audited specifically for tax purposes.

The auditor verifies that the books of accounts are properly maintained, income is correctly reported, and deductions are legitimately claimed. The audit report is submitted in prescribed forms (3CA/3CB and 3CD) to the Income Tax Department.

Tax audit serves multiple important purposes:

  • Ensures Compliance: Verifies adherence to income tax laws and regulations
  • Proper Record Maintenance: Confirms that books of accounts are correctly maintained
  • Accuracy Verification: Ensures income is accurately reported and deductions are valid
  • Fraud Prevention: Helps detect and prevent fraudulent practices
  • Facilitates Assessment: Saves time for tax authorities by providing verified financial data
  • Standardized Reporting: Provides uniform information through prescribed audit forms

Tax audit is mandatory for the following taxpayers:

For Businesses:
  • Annual turnover exceeding ₹1 crore (increased to ₹10 crore if cash transactions are below 5%)
  • Exceptions: Businesses opting for presumptive taxation under Section 44AD with turnover up to ₹2 crore
For Professionals:
  • Annual gross receipts exceeding ₹50 lakhs
Special Cases:
  • Taxpayers opting out of presumptive taxation scheme
  • Those declaring lower profits than presumptive scheme rates
  • Certain specified businesses like civil construction, mineral oil exploration, etc.

No, separate tax audit is not required. Companies and cooperative societies that are already required to get statutory audit under their respective laws don't need a separate tax audit.

In such cases, the Chartered Accountant can provide a combined report using:

  • Form 3CA: For audit report (when audit is done under other laws)
  • Form 3CD: For prescribed particulars and statements

This eliminates duplication of audit work while meeting tax compliance requirements.

These are prescribed forms for tax audit reporting:

Form 3CA & 3CB:
  • Form 3CA: Used when taxpayer is already audited under other laws
  • Form 3CB: Used when audit is conducted specifically under Section 44AB
Form 3CD:
  • Contains detailed particulars and statements
  • Includes financial information, compliance details, and auditor's observations
  • Common to both Form 3CA and 3CB submissions

The tax audit report must be obtained and filed by 30th September of the relevant assessment year.

Example:
Financial Year 2025-26 (Assessment Year 2026-27)
Due Date: 30th September 2026
Filing Process:
  1. Chartered Accountant files the audit report electronically
  2. Taxpayer approves the report through e-filing portal
  3. Submission completed on Income Tax Department's website

Failure to comply with tax audit requirements under Section 44AB attracts penalty under Section 271B:

Penalty Amount (Whichever is lower):
  • 0.5% of total turnover/gross receipts
  • Maximum ₹1,50,000
Important: No penalty is imposed if the taxpayer can prove reasonable cause for the delay or failure in getting the audit done.

The CA audits the books of accounts like the cash book, ledger, journals, bank statements, stock records, and sales/purchase invoices. Authenticates the state of affairs of business as on the last date of the financial year.

If a tax audit is applicable but not conducted, it attracts penal consequences under Section 271B. The Assessing Officer can levy a penalty of Rs 1.5 lakh or 0.5% of turnover, which is lower. Prosecution can also be initiated. Non-submission of audit reports makes the return defective, and provisions for faulty returns apply.

Tax audits for salaried persons are generally not subject to a tax audit. However, if one has income from any other source, like professional fees exceeding Rs 50 lakhs or business income exceeding Rs 1 crore, then in that case tax audit may be applicable. Having turnover/gross receipts from business/profession exceeding the limits makes one liable for a tax audit.

Form 3CA is the tax audit report filed by the Chartered Accountant. It certifies that the audit was conducted as per the provisions of Section 44AB. Form 3CD is the statement of particulars in a prescribed format that needs to be submitted along with the Return and Form 3CA. It provides details of deductions claimed, compliance, etc.

Only a Chartered Accountant holding a valid Certificate of Practice (COP) can conduct a tax audit as per Section 44AB as per Section 288(2).

Turnover limit for applicability of tax audits to businesses is Rs. 1 crore. However, the limit should be increased to Rs. 10 crores if the cash receipts / cash payments does not exceed 5% of the total receipts / total payments.

In that case, the due date for furnishing tax audit report is 31st October of the Assessment year.

In that case penalty will be imposed at the lower of:

  • 0.5% of total turnover or receipts; or
  • Rs. 1.5 lakhs.

Yes, it is mandatory for taxpayers who have to audit their books of account under any law.

The tax audit limit under 44AB is Rs 1 crore. However, the threshold is Rs 10 crore if 95% of the transaction is digital.

No, tax audit applicability is ascertained with reference to each previous year. It is not necessary that tax audit applicable for one year will be applicable for all the subsequent years.

No, persons engaged in a profession are not entitled to avail the extended turnover limit of Rs. 10 crores for tax audit in the case of digital transactions. This benefit is available only to the assessees carrying on a business.

Yes, tax audit reports can be revised under special circumstances, such as changes in tax law or its interpretation, errors due to a software glitch, or if a company is adopted in the AGM.

If you cross the limits as provided in Section 44AA for the business/profession, then you are required to maintain the books of accounts.

No, the requirement of maintaining books of accounts does not apply to a salaried person.

No, there is no relaxation to maintain books of accounts if you opt for new regime.

No, in case you opt for presumptive taxation, you will not be required to maintain books of accounts.
