Assuming, one reports a profit % less than the presumptive rates (6%/8%/50%) used earlier.
Opting out + reporting a Higher profit means tax audit is applicable only based on the turnover condition, not because of opting out. Here, Turnover becomes the criteria, not the action of opting out.
I.e., Tax audit applies only if you satisfy both conditions of, Opting out and claiming lower profits. The act of opting-out doesn’t automatically mandate tax audit, if you are reporting a higher profit than the profit % reported under presumptive taxation.
I.e., One cannot keep switching between presumptive taxation and normal taxation for the benefit of oneself, however, if the switch from presumptive to normal taxation results in the benefit of the Govt, by the way of higher profit %, the tax audit is not required.
Tax Audit Applicability
A tax audit is only applicable when you opt out of presumptive taxation (Section 44AD/44ADA) and report profits lower than the prescribed presumptive rate (6%/8% for business, 50% for professionals).
Key Aspects of Tax Audit Applicability:
Opting Out + Lower Profit: If you have previously claimed presumptive taxation and decide to report lower profits, you must maintain books of accounts and get a tax audit done.
Opting Out + Higher Profit: If you opt out but still report profits equal to or higher than the 6%/8%/50% rates, a tax audit is not mandatory solely due to the opt-out, provided your turnover is below the regular audit threshold.
The 5-Year Lock-in Rule: Under Section 44AD, if you opt out of the presumptive scheme, you cannot claim it for the next five years, which often triggers the audit requirement if your actual profits are low.
Thresholds: Regardless of presumptive taxation, a tax audit is mandatory if business turnover exceeds ₹1 crore (or ₹10 crore if 95% of transactions are digital) or for professionals with gross receipts over ₹50 lakh or ₹75 lakh if 95% receipts are digital.
In summary, the audit is a consequence of “opting out + claiming lower profits,” not just the act of opting out itself.
