Tax Audit under Section 44AB: Who Needs One and When
A tax audit is not a sign that something is wrong. It is a statutory requirement that kicks in once your business crosses certain thresholds, and the main risk is simply not realising you have crossed one.
The basic thresholds
For a business, tax audit under Section 44AB applies where total sales, turnover or gross receipts exceed ₹1 crore in the financial year. That limit is raised substantially — to ₹10 crore — where both cash receipts and cash payments are 5% or less of the respective totals. Digital businesses very often qualify for the higher limit without realising it.
For a profession, the threshold is gross receipts exceeding ₹50 lakh.
The 5% test is the part most people get wrong. It is not "mostly digital" — it is a hard percentage tested on both sides, receipts and payments. A single large cash payment can push you over and drop you back to the ₹1 crore limit.
Presumptive taxation changes the answer
If you previously declared income under Section 44AD and then declare profit below the presumptive rate while your total income exceeds the basic exemption limit, audit is triggered — regardless of turnover. The same logic applies to professionals under 44ADA.
This catches people who used presumptive taxation in a good year, had a poor year, and assumed opting out was cost-free. It is not; opting out has consequences for several subsequent years.
What actually gets filed
- Form 3CA where the accounts are already audited under another law, such as the Companies Act
- Form 3CB where they are not
- Form 3CD, the detailed statement of particulars, accompanies both
Form 3CD is long and specific. It asks about related party transactions, loans accepted and repaid in cash, disallowances, TDS defaults and much more. Most of the time spent on a tax audit goes here, not on the balance sheet.
Due dates and consequences
The audit report must be filed before the specified date, ahead of the return filing deadline for audited assessees. Miss it and the penalty under Section 271B is 0.5% of turnover, subject to a ceiling — with relief available where there is reasonable cause.
The indirect cost is usually worse. A late audit report delays the return, which delays refunds and can affect loan applications and tender eligibility where audited accounts are required.
Preparing well
The audits that go smoothly are the ones where the books were reconciled through the year, not in September. Keep your GST turnover reconciled to your books, your TDS deducted and deposited on time, and your cash transactions documented. Every one of those is a line item in Form 3CD.
