Section 44AB Tax Audit in India: Applicability, Limits, Due Date, Penalty

Income Tax Act 2025 Update

• The Income Tax Act, 2025 have replaced the terms Previous Year & Assessment Year with the term Tax Year. For example, if the income was earned in the year 2025-26, it will be called Tax Year 2025-26. However, since many taxpayers are still familiar with the terms Financial Year (FY) and Assessment Year (AY), this guide continues to use them for easier understanding.
• The new Income Tax Act has renumbered most of the sections and simplified them by reducing the number of sections, schedules, etc.

You can refer to the complete section mapping of Income Tax Act 1961 vs Income Tax Act 2025 here.

What is Tax Audit?

A tax audit is a mandatory examination and verification of the books of accounts of certain taxpayers carrying on a business or profession, as required under the Income Tax Act. It involves a detailed review of income, expenses, deductions, and other financial transactions to ensure correct computation of taxable income and proper compliance with tax laws. A tax audit also helps in the accurate and timely filing of income tax returns and reduces the chances of errors or discrepancies.

44AD and 44ADA: When Tax Audit Becomes Mandatory

Yes, a tax audit under section 44AB can still be required, even if you opt for presumptive taxation under section 44AD or 44ADA. It depends on your turnover or receipts and how much of it is received in cash.

The turnover limits for presumptive taxation increase when cash receipts are not more than 5% of total receipts:

Section 44AD (for business):

• Up to ₹3 crore if cash receipts are ≤ 5%
• Up to ₹2 crore if cash receipts are more than 5%

Section 44ADA (for professionals):

• Up to ₹75 lakh if cash receipts are ≤ 5%
• Up to ₹50 lakh if cash receipts are more than 5%

If your turnover or professional receipts exceed these limits, a tax audit under section 44AB becomes applicable, even if you have opted for presumptive taxation.

Types of Penalties for Not Filing Tax Audit Report in India

If a taxpayer is required to get accounts audited under Section 44AB, the tax audit report must be completed and filed within the prescribed due date. Not complying with this requirement can attract penalties under the Income Tax Act.

1. Penalty under Section 271B

If a taxpayer fails to get the tax audit done or does not file the tax audit report on time, the Assessing Officer can levy a penalty under Section 271B.

The penalty is calculated as:

• 0.5% of total sales, turnover, or gross receipts of the business or profession
  OR
• ₹1,50,000, whichever is lower.

This penalty applies even if:

• The audit is completed but the report is filed late, or
• The audit report is not uploaded correctly on the income tax portal.

2. When Penalty May Not Apply (Section 273B)

Penalty under Section 271B may not be imposed if the taxpayer can prove there was a reasonable cause for the failure. This relief is provided under Section 273B of the Income Tax Act.

Some commonly accepted reasonable causes include:

Other Consequences of Not Filing a Tax Audit Report

Failing to file a tax audit report when required by tax authorities can lead to various penalties and consequences, which can vary depending on the jurisdiction and tax laws applicable to your situation. Here are some common penalties and consequences associated with not filing a tax audit report:

• Monetary Penalties: Tax authorities may impose monetary penalties for not filing a tax audit report. These penalties are typically calculated as a percentage of the tax liability or income subject to audit, and they can be substantial.
• Disallowance of Deductions: In some cases, tax authorities may disallow certain deductions or exemptions claimed on your tax return if you fail to file a required tax audit report. This can result in a higher tax liability.
• Interest Charges: Interest charges may accrue on any unpaid tax liability that results from not filing a tax audit report. The interest rate and calculation method can vary by jurisdiction.
• Legal Action: In severe cases or for repeated non-compliance, tax authorities may take legal action against you. This could involve fines, penalties, and even criminal charges in some instances.
• Loss of Tax Benefits: Failure to file a tax audit report can also lead to a loss of tax benefits or incentives that you might be entitled to.
• Audit: Not filing a tax audit report may trigger a tax audit by the tax authorities. During the audit, they will review your financial records and tax returns, which can be a time-consuming and potentially costly process.
• Impact on Credit Rating: In some jurisdictions, tax authorities can report tax debts to credit agencies, which can negatively affect your credit rating.
• Injunctions and Seizures: In extreme cases of non-compliance, tax authorities may seek court orders to place liens on your assets, garnish wages, or seize property to satisfy unpaid tax debts.

Section 44AB Applicability Checklist (Business vs Profession)

Section 44AB of the Income Tax Act says that some taxpayers must get their accounts audited if their business or profession crosses certain limits. Here’s a simple checklist to know when tax audit is needed:

For Business:

• If your total sales, turnover, or gross receipts are more than ₹1 crore in a financial year, you must get your accounts audited.
• If your business mostly deals in cash and cash receipts and payments are less than 5% of total receipts/payments, then the limit increases to ₹10 crore.
• If you run a business under presumptive taxation scheme (like Section 44AD) but declare profits less than the prescribed rate and your income is above the basic exemption limit, then you need an audit even if turnover is below ₹1 crore.

For Profession:

• If your gross receipts from profession exceed ₹50 lakh in a financial year, you must get your accounts audited.
• If you follow the presumptive taxation scheme under Section 44ADA and declare profits less than 50% of your receipts, and your income is above the basic exemption limit, audit is required.

If You Have Both Business and Profession:

• Check both separately. If either your business or profession crosses the limit, you need to get your accounts audited.

Which Tax Audit Forms Apply (3CA vs 3CB & Annexure 3CD)

When you are required to get a tax audit done under Section 44AB, different forms are used depending on whether your accounts are already audited by a chartered accountant or not.

Form 3CA

• Use Form 3CA if your accounts have already been audited by a Chartered Accountant under any other law (like the Companies Act).
• This form certifies that you have complied with the audit requirements under other laws, and now your income tax audit is also done as per Income Tax rules.
• You still need to file Annexure 3CD along with Form 3CA, which gives detailed information about your accounts and tax details.

Form 3CB

• Use Form 3CB if your accounts have NOT been audited under any other law.
• This is a direct audit report specifically done under the Income Tax Act.
• Like Form 3CA, Annexure 3CD must also be filed along with Form 3CB.

Annexure 3CD

• This is a detailed statement of information required by the Income Tax Department.
• It contains important details like your turnover, expenses, assets, liabilities, loans, and other relevant data.
• It must be filed along with either Form 3CA or 3CB.

Cases Where Accounts are Audited Under any Law Other than the Income Tax Act

If a taxpayer is required to get his books of accounts audited under any other law, for example, a statutory audit of companies under company law provisions, the individual need not conduct his audit again for taxation purposes. The taxpayer just has to get the audit report furnished according to the income tax law before the due date of filing of the return.

If you are a taxpayer, you must comply with the provisions of section 44AB of the Income Tax Act 1961. This section states that all taxpayers have to get an audit report furnished after conducting an audit of their books of accounts. This is to truly reflect the taxpayers' income-related activities, deductions, and taxes. Need help with a tax audit? Get in touch with our tax experts to ensure accuracy in tax matters.
