Income Tax Audit u/s 44AB: Limits, Due Date & Penalties (AY 2025–26)

Filing your income tax return means, for some taxpayers, a tax audit is non-negotiable. It’s like a financial health check-up by a chartered accountant to make sure your books are squeaky clean and playing by the rules.

So, who actually needs one? If your business turnover crosses ₹1 crore (₹2 crore if you’re on presumptive schemes) or if you’re a professional earning over ₹50 lakh, congratulations—you’re on the audit radar!

But here’s the kicker: not everyone’s in this club. Audit rules depend on your turnover, receipts, or professional income. If you don’t hit those numbers, you can breathe easy (for now).

Heads up, the deadline for FY 2024–25 audits is 30th September 2025 (unless there’s an extension). Miss it, and penalties up to 0.5% of your turnover or receipts might come knocking. Ouch.

Bottom line? Knowing your audit rules isn’t just about ticking boxes. It’s your secret weapon for filing your tax return without a hitch—and keeping penalties far, far away. And if you’re curious how this audit puzzle fits into your ITR journey, take a peek at ITR Filing Fundamentals for AY 2025–26.

1. What is an Income Tax Audit u/s 44AB?

An income tax audit u/s 44AB is basically a CA-powered health check for your finances—mandatory, precise, and definitely not a spa day. It’s when a chartered accountant dives into your books, income, and deductions to make sure everything’s playing by the Income Tax Act’s rulebook. Think of it as the official answer to “what’s a tax audit really,” a neat way to keep your financial game transparent and audit-proof.

And if you’ve ever wondered what the difference is between an auditor and a compliance officer (spoiler: they’re not the same!), check out this surprisingly handy breakdown here: difference between auditor & compliance officer.

Tax Audit Applicability Under Section 44AB

Whether you need one depends on your turnover, receipts, or professional income:

• Businesses – Turnover above ₹1 crore (or ₹2 crore under presumptive taxation).
• Professionals – Gross receipts above ₹50 lakh.
• Certain taxpayers opting out of presumptive taxation may also fall under audit rules.

Miss it? Expect penalties and potential legal headaches.

Objectives of the audit

The audit isn’t just box-ticking; it serves a purpose:

• Ensuring compliance – Checks if you’re following the Act.
• Accuracy of accounts – Confirms that income, expenses, and deductions are reported correctly.
• Transparency – Builds trust with banks, investors, and the tax department.

In short, a tax audit u/s 44AB is more than a legal must-do; it’s your ticket to clean books and stress-free compliance.

2. Applicability of Section 44AB in ITR Filing for AY 2025–26

Tax audit rules aren’t one-size-fits-all—they depend on your turnover, receipts, and whether you’re cruising the presumptive taxation “fast lane” for small businesses. Here’s the lowdown for FY 2024–25 (AY 2025–26):

For Businesses

• Turnover Threshold: If your business turnover crosses ₹1 crore, buckle up—you’re in audit territory.
• Presumptive Taxation Perk: Opt for presumptive taxation under Section 44AD, declare your income at the set rate (8%, or 6% if you’re rolling with digital receipts), and voilà, your audit threshold doubles to ₹2 crore.

For Professionals

• Gross Receipts Limit: Professionals must get their books audited if their gross receipts exceed ₹50 lakh in a financial year.

Special Cases

Even if turnover or receipts are within limits, a tax audit might still be required if you declare income below the prescribed percentage under presumptive schemes (44AD, 44ADA, 44AE).

Tax Audit Applicability Table – FY 2024–25

Category	Turnover / Gross Receipts	Audit Required?
Business (Normal)	> ₹1 crore	Yes

4. Forms Used for Tax Audit

Form	Applicability	Key Points / Details
3CA	When accounts are already audited under any other law (e.g., Companies Act)	Tax audit report under Section 44AB is attached along with this form.
3CB	When accounts are not audited under any other law	A Chartered Accountant certifies accounts solely for income tax audit purposes.
3CD	Must be filed along with Form 3CA or 3CB	– Detailed statement with 41 clauses – Includes turnover/gross receipts, income under presumptive schemes, deductions, loans, advances, and other financial transactions

Penalty u/s 271B – Amount & Calculation

• If a taxpayer fails to get the books of accounts audited as required under Section 44AB, a penalty is imposed.
• Amount of Penalty:
  • 0.5% of the total turnover or gross receipts of the business or profession for the relevant financial year.
  • However, the penalty is capped at ₹1,50,000, even if the calculated amount exceeds this limit.
    
• Example:
  • If turnover is ₹5 crore and audit is not done, penalty = 0.5% × ₹5 crore = ₹2,50,000.
  • But the maximum penalty chargeable is ₹1,50,000.

Relief Under Section 273B – Reasonable Cause

• Penalty may not be levied if the taxpayer proves a reasonable cause for non-compliance.
• Common examples of reasonable cause include:
  • Natural disasters – Floods, earthquakes, or fires can destroy your books of accounts, making timely filing impossible.
  • Health emergencies – Serious illness or death of the taxpayer or key accounting staff can disrupt record-keeping.
  • Technical issues – Glitches in the Income Tax e-filing portal may prevent a successful submission.
  • Uncontrollable events – Strikes, riots, or other disruptions can affect normal business operations and filings.

Key Point: If you miss the deadline, the spotlight’s on you, you’ll need to prove why it wasn’t your fault.

Why Timely Compliance Matters

• Avoid penalty punches: Section 271B fines? Nope, thanks!
• Dodge the tax spotlight: Stay off the auditors’ radar and skip extra questions.
• Score credibility points: Keep banks, investors, and regulators smiling.
• Smooth sailing for ITRs: Faster refunds, fewer headaches, more happy dances.

Pro Tip: Think of a tax audit as a financial check-up, not a courtroom drama. On-time audits = trust points + peace of mind.
