Why Your Zerodha Turnover Doesn't Match Your CA's Number
Note: This is general information, not tax advice, and tax rules change. Verify the current figures against the Income Tax Act, the relevant Finance Act and ICAI guidance, and confirm your own position with a qualified Chartered Accountant.
Two definitions of turnover
The word turnover means different things in different places. Brokers may show a figure based on traded value or an older turnover basis. For income tax, turnover has a specific meaning set by ICAI: the absolute sum of realised profit and loss. These are not the same number, and they can differ by a lot.
The option-premium add-back is the usual culprit
The biggest historical gap is options. The pre-2022 method added the premium received on the sale of options to turnover. For an active option seller, that premium runs into lakhs and inflates turnover dramatically. The ICAI 8th-edition Guidance Note (14 August 2022, AY 2022-23 onward) removed the add-back. If a report still includes it, its turnover will be far higher than the correct figure.
Why it matters: the wrong number can trigger a false alarm
Turnover does not change your tax, only audit applicability. But an inflated broker number can push you over the โน2 crore 44AD line or scare you toward a โน10 crore audit you do not owe. Working off the correct ICAI figure keeps you out of unnecessary audit territory. Check your real position on the audit checker.
Reconcile it
Recompute turnover the ICAI way from your realised P/L. The F&O turnover calculator does it in seconds, and the method is explained in how to calculate F&O turnover. If you trade on more than one broker, you also need to combine them, see multi-broker turnover. Aktai Tax does both from your statements.
Frequently asked questions
Why is my Zerodha Console turnover higher than my CA figure?
Console and many broker reports can compute turnover on a basis that differs from the current ICAI absolute-sum method, and older methods added option sell-side premium. The ICAI figure your CA uses is usually smaller. When they differ, the ICAI method is the one the audit thresholds and your return use.
Which turnover number is correct for tax?
The ICAI absolute-sum of realised profit and loss, with no option-premium add-back since the August 2022 guidance note. That is the figure for audit applicability and your ITR-3.
Does the higher number mean I owe more tax?
No. Turnover is not income and does not change your tax. It only affects whether an audit applies. An inflated turnover can wrongly suggest you need an audit when you do not.
