Tax audit applicability is one of the most confusing areas for retail stock and options traders. Many traders believe that declaring a loss in the stock market automatically triggers a mandatory tax audit by a Chartered Accountant. This is a myth. Let's clarify the legal rules under Section 44AB for Assessment Year 2026-27.

When is a Tax Audit Mandatory for Traders?

A tax audit is required only when specific conditions regarding turnover and income limits are met:

1. Turnover Exceeds the Limit: If your absolute turnover exceeds ₹10 Crore (for digital transactions, which covers all online stock brokers), a tax audit is mandatory.
2. Declaring Loss with Low Income: If your total income exceeds the basic exemption limit and you claim that your trading profits are lower than 6% of your turnover (or you declare a net trading loss) AND you want to carry forward this loss, a tax audit is required.

When is an Audit NOT Required?

If your total income (including salary, interest, and house property) is below the basic exemption limit, you do not need an audit, even if you have trading losses. Furthermore, if you decide not to carry forward your losses to offset future profits, you can file your ITR-3 without a tax audit.

Key Deadlines to Note

If a tax audit applies to you under Section 44AB:

• The deadline to file your tax return shifts from July 31st to October 31st of the assessment year.
• The tax audit report must be submitted online by a registered CA by September 30th.
