What Exactly Is Trading Turnover?
Most traders confuse turnover with trading volume, but they are fundamentally different. Volume refers to the number of shares traded, while turnover, in the context of tax compliance in India, is a specific calculation of the value of your trades. It
is not your net profit, nor is it the total value of assets you bought and sold. Instead, it’s a measure defined by tax authorities to gauge the scale of your trading business. Thinking of your trading activity as a business is the first step, as income from intraday equity and Futures & Options (F&O) trading is classified as business income under the Income Tax Act. Therefore, understanding turnover is not just good practice—it's a legal requirement.
Why Turnover Is a Critical Metric
The primary reason to track turnover meticulously is for tax purposes. Your trading turnover is the key determinant for whether you are required to get your accounts audited by a Chartered Accountant under Section 44AB of the Income Tax Act. Crossing a certain turnover threshold triggers a mandatory tax audit. For traders, this threshold is generally Rs 10 crore, provided at least 95% of transactions are digital, which is the case for nearly all online stockbrokers. If your turnover exceeds this limit, an audit is compulsory, regardless of profit or loss. A second scenario involves declaring profits below a certain level. If you don't opt for the presumptive taxation scheme, or if you declare profits lower than 6% of your turnover (while having income above the basic exemption limit), an audit may become necessary even with a lower turnover.
Calculating for Equity Trades
The method for calculating turnover differs by trading segment. For speculative transactions like intraday equity trading, turnover is the 'absolute profit'. This means you sum up the positive and negative differences from all your trades. For example, if you make a profit of Rs 5,000 on one trade and a loss of Rs 3,000 on another, your turnover is Rs 8,000 (5,000 + 3,000). You ignore the minus sign on the loss. For delivery-based trades, where you hold stocks for more than a day, the calculation is different. If you choose to declare this as business income (instead of capital gains), the turnover is simply the total selling value of the shares. For instance, if you sell shares worth Rs 2 lakh, your turnover for that transaction is Rs 2 lakh.
The Tricky Case of F&O Turnover
This is where many traders get it wrong. For Futures and Options (F&O), the turnover is not the contract value. According to guidance from the Institute of Chartered Accountants of India (ICAI), turnover for F&O is also based on absolute profit. For futures, you calculate the sum of all your profits and losses (taking the absolute value of each). For example, a profit of Rs 20,000 and a loss of Rs 15,000 results in a turnover of Rs 35,000. For options, the calculation includes the absolute profit plus the premium received when you sell or write an option. This method prevents the turnover figure from becoming astronomically large due to high notional contract values and focuses on the actual money gained or lost, plus premiums received. Many brokerage platforms now provide a tax profit-and-loss statement that calculates this figure for you.
Practical Tips for Easy Tracking
Staying on top of your turnover shouldn't be a year-end scramble. First, leverage the tools your broker provides. Most major Indian brokerages offer detailed tax P&L and turnover reports that can be downloaded for the financial year. These reports typically segregate trades by segment (intraday, F&O) and calculate turnover according to ICAI guidelines. Second, maintain a simple spreadsheet. At the end of each month, update it with the profit, loss, and turnover figures from your broker's report. This gives you a running total and helps you anticipate if you're approaching the tax audit threshold. Finally, remember that expenses related to your trading business, such as brokerage fees, STT, exchange transaction charges, internet bills, and software subscriptions, can be claimed to reduce your taxable income. Keeping a record of these is just as important.
