F&O Trading Income Tax Guide for FY 2025–26 (AY 2026–27): Turnover, ITR, Tax Audit and Loss Rules

Futures and Options trading has become increasingly popular among Indian market participants. But when the financial year ends, many traders are unsure how their F&O profits and losses should be reported in the income-tax return.

Is F&O income treated as capital gains? Which ITR should be filed? How is turnover calculated? Does a loss require a tax audit? Can F&O losses be carried forward?

The answers are different from the tax treatment of ordinary long-term investing.

This guide explains the general tax treatment of exchange-traded F&O transactions for FY 2025–26, corresponding to Assessment Year 2026–27.

Important Note About the Income Tax Act, 2025

The Income Tax Act, 2025 came into force from 1 April 2026, replacing the Income-tax Act, 1961 for income earned from FY 2026–27 onward.

However, income earned during FY 2025–26 continues to be governed by the Income-tax Act, 1961.

Therefore, a return being filed for AY 2026–27 relates to FY 2025–26 and continues to follow the applicable provisions of the Income-tax Act, 1961.

The Income Tax Department has specifically clarified that returns for AY 2026–27 continue under the earlier Act even though those returns may be filed after 1 April 2026.

F&O Taxation at a Glance

How Is F&O Income Classified?

One of the biggest misconceptions is that every transaction involving shares or stock-market instruments is taxed as capital gains.

That is not normally how eligible exchange-traded Futures and Options transactions are treated.

Under Section 43(5) of the Income-tax Act, 1961, eligible derivative transactions carried out on a recognised stock exchange are excluded from the definition of speculative transactions.

For an individual who conducts F&O trading as a business activity, the resulting profit or loss is generally reported under:

Profits and Gains from Business or Profession

This is why the tax-return requirements for an active F&O trader can be different from those of an investor who simply buys and holds shares.

Which ITR Form Is Generally Used for F&O Trading?

For individuals and Hindu Undivided Families having income from business or profession, ITR-3 is generally the relevant return.

The Income Tax Department describes ITR-3 as applicable to individuals and HUFs having income from profits and gains of business or profession.

A person should therefore not automatically file ITR-2 simply because the trading activity involves securities.

If F&O income is being treated as business income, ITR-3 will normally need to be considered.

Can an F&O Trader Use ITR-4?

ITR-4 is designed for eligible resident individuals, HUFs and firms other than LLPs whose income meets the prescribed conditions and whose business or professional income is reported under eligible presumptive-taxation provisions.

Section 44AD provides a presumptive-taxation framework for eligible businesses, subject to several conditions. Its normal turnover ceiling is ₹2 crore, which can increase to ₹3 crore where cash receipts do not exceed 5% of total turnover or gross receipts.

However, an F&O trader should not automatically assume that Section 44AD or ITR-4 applies simply because turnover falls below the threshold.

Eligibility depends on the taxpayer, nature of activity, reporting position and all applicable conditions.

Where there is uncertainty—particularly with substantial trading activity, losses, tax-audit considerations or multiple income sources—professional tax advice may be useful.

How Is F&O Turnover Calculated?

F&O turnover for income-tax and tax-audit purposes is not normally calculated by adding the full contract value of every Futures or Options trade.

That would produce an unrealistically large number because derivative contracts provide leveraged exposure to an underlying instrument.

For squared-off derivatives, tax-audit guidance has generally focused on the aggregate of favourable and unfavourable differences.

In simple terms, both profits and losses are considered as positive values while calculating turnover for this purpose.

Simple F&O Turnover Example

Assume a trader has the following closed transactions during the year:

The ₹35,000 loss is not deducted from the profitable transactions when calculating turnover. Its absolute amount forms part of turnover.

ICAI's tax-audit guidance describes the aggregation of favourable and unfavourable differences for derivatives. It also provides specific guidance for treatment of option premium and reverse trades.

Options Require Additional Care

Options can make turnover calculation more complicated.

Premium received on sale of options may need to be considered according to the applicable ICAI tax-audit methodology, but care is required to ensure that the same economic amount is not counted twice.

Because turnover can determine whether tax-audit provisions apply, traders with significant Options activity should reconcile their calculations with their broker's tax P&L statement, books of account and the latest ICAI guidance.

Is Contract Value the Same as Turnover?

No.

Suppose a trader buys and sells Nifty Futures contracts whose notional contract value runs into several crores during the year.

That does not necessarily mean the trader has several crores of F&O turnover for tax-audit purposes.

For derivatives, turnover calculation follows the applicable tax-accounting methodology rather than simply adding the underlying notional value of every contract.

This distinction is extremely important when evaluating tax-audit requirements.

When Is a Tax Audit Required?

Section 44AB contains the principal tax-audit rules for businesses.

For business, the standard turnover threshold is generally:

₹1 crore

However, the threshold can increase to:

₹10 crore

where cash receipts and cash payments each do not exceed the prescribed 5% limit.

Since most exchange-traded F&O transactions and broker settlements are electronic, the higher threshold can be relevant in appropriate cases.

However, turnover alone should not be treated as the only possible audit consideration.

Tax-audit applicability can also depend on matters such as presumptive-taxation provisions, profit declarations and the taxpayer's individual circumstances.

Therefore:

A trading loss does not automatically mean a tax audit is mandatory.

Likewise:

A profitable trader is not automatically exempt from audit.

The complete facts need to be examined.

Can Section 44AD Apply?

Section 44AD allows eligible taxpayers carrying on eligible businesses to report presumptive income at prescribed rates instead of calculating taxable profit under the normal business-income provisions.

Under the framework applicable to FY 2025–26, presumptive income is generally calculated at 8% of applicable turnover or gross receipts, with a 6% rate for qualifying non-cash receipts, subject to the statutory conditions.

The eligible-business turnover ceiling can rise from ₹2 crore to ₹3 crore where cash receipts do not exceed 5%.

For F&O traders, however, the decision to use presumptive taxation should not be made solely to simplify the return.

A taxpayer should first establish eligibility and understand the consequences, particularly when actual profits are lower than the presumptive amount or when losses have been incurred.

The Five-Year Rule Under Section 44AD

Section 44AD also contains an important continuity rule.

If an eligible taxpayer declares profits under Section 44AD and then fails to declare income in accordance with the scheme during one of the following five assessment years, the taxpayer may become ineligible to use Section 44AD for the subsequent five assessment years.

This means moving into and out of presumptive taxation can have consequences beyond a single tax return.

Traders should therefore understand the longer-term implications before choosing the presumptive route.

Can F&O Trading Expenses Be Deducted?

Where F&O income is reported under the normal business-income provisions, expenses incurred wholly and exclusively for the business may generally be considered for deduction, subject to the Income-tax Act and proper documentation.

Depending on the facts, relevant expenses could include brokerage, exchange charges, eligible data or software costs, professional fees, internet expenses attributable to the business and depreciation on qualifying assets used for the trading activity.

Personal expenses should not be claimed as business deductions merely because the taxpayer trades in the financial markets.

Proper records should be maintained to support material expenses.

If income is reported under an eligible presumptive-taxation scheme, separate deductions for normal business expenses are generally treated differently because the presumptive profit itself is intended to represent taxable business income.

What Happens If You Have an F&O Loss?

A genuine F&O business loss is not automatically wasted.

Because eligible exchange-traded F&O activity is generally treated as non-speculative business activity, the resulting business loss may be eligible for set-off and carry-forward under the applicable rules.

A non-speculative business loss cannot be set off against salary income.

If the loss cannot be fully absorbed in the same year, it may generally be carried forward for up to eight assessment years and used against eligible business income in subsequent years.

Timely Filing Is Very Important

To preserve the ability to carry forward eligible business losses, the return of loss generally needs to be filed within the prescribed due date.

The Income Tax Department's guidance confirms that business losses cannot ordinarily be carried forward unless the return is filed in accordance with the relevant loss-return requirements.

This is one reason F&O traders should avoid ignoring the ITR simply because they made a loss.

Advance Tax for F&O Traders

F&O traders can also become liable to pay advance tax.

Advance tax generally becomes applicable where the estimated tax liability for the year, after considering eligible credits such as TDS and TCS, is ₹10,000 or more.

For taxpayers following the normal advance-tax schedule, cumulative installments are generally:

Taxpayers using qualifying presumptive-taxation provisions have a different advance-tax schedule and may generally pay the full advance-tax liability by 15 March.

For active traders, estimating profit during the year can be difficult because profits may change sharply during volatile market periods.

Nevertheless, advance-tax requirements should not be ignored, as shortfalls or delays can result in interest.

Worked Example: F&O Profit and Tax Reporting

Consider an illustrative taxpayer who has the following income during FY 2025–26:

F&O trading profit before expenses: ₹4,20,000

Eligible business expenses: ₹70,000

Salary income: ₹8,00,000

The net F&O business income under normal business-income computation would be:

₹4,20,000 − ₹70,000 = ₹3,50,000

The ₹3.5 lakh does not become a separate special-rate F&O tax.

It forms part of the taxpayer's business income and is considered along with other taxable income when computing the overall tax liability under the applicable tax regime.

However, F&O turnover for tax-audit purposes is a separate calculation and should not be assumed to equal the ₹4.2 lakh trading profit.

The taxpayer must separately consider the applicable ITR, tax regime, turnover, audit position, advance tax and other tax provisions.

This example is only illustrative.

Keep Proper Trading Records

F&O traders should maintain organised records rather than relying only on the final net profit shown in a broker application.

Useful documentation may include the broker's tax P&L statement, trade book, ledger, contract notes, bank statements, expense records, turnover workings and copies of the income-tax return and supporting calculations.

Maintaining proper documentation becomes particularly important where trading volumes are high, losses are being carried forward or a tax audit is applicable.

Common Mistakes F&O Traders Should Avoid

Some of the most common problems arise from treating F&O trading like ordinary investing, calculating turnover using full contract value, assuming every loss requires a tax audit, ignoring loss-return filing deadlines, selecting the wrong ITR, claiming personal expenses as business costs, or choosing presumptive taxation without understanding its eligibility and long-term consequences.

Another frequent mistake is waiting until the last moment to obtain broker statements and calculate turnover.

Tax compliance is much easier when trading records are reconciled throughout the year.

Final Takeaway

The taxation of F&O trading is different from the taxation of ordinary delivery-based investing.

Eligible exchange-traded derivative transactions are generally treated as non-speculative transactions, and active traders normally report the resulting profit or loss under business income.

For individuals and HUFs with such business income, ITR-3 is generally the relevant return.

The most important point is that F&O turnover is not simply the total contract value traded. Turnover must be calculated using the appropriate tax-audit methodology, and that figure can influence whether audit provisions apply.

F&O losses can also have tax value because eligible business losses may be carried forward for up to eight assessment years, but timely filing of the return is important.

Traders should therefore focus on correct classification, accurate turnover calculation, proper records and timely compliance rather than treating taxation as an afterthought.
