⚡ Quick answer

A tax audit under Section 44AB is mandatory if your business turnover exceeds ₹1 crore (raised to ₹10 crore where at least 95% of receipts and payments are digital), or professional gross receipts exceed ₹50 lakh. It's also required if you declare profits below the presumptive rate (44AD/44ADA) and your income exceeds the basic exemption.

1The thresholds

Business: ₹1 crore turnover, or ₹10 crore if cash receipts and payments are each ≤5%. Profession: ₹50 lakh receipts. Presumptive opt-out below the deemed rate also triggers an audit.

2The process

A Chartered Accountant audits your accounts and files Form 3CA/3CB along with Form 3CD. The tax-audit report is generally due by 30 September of the assessment year; late filing attracts a penalty under Section 271B.
