F&O Tax in India FY 2025-26 — Rates, Audit Threshold & Filing Guide

1. How F&O income is classified

The Income Tax Act 1961 — specifically Section 43(5) — classifies F&O trades in derivatives on a recognised stock exchange as non-speculative business income. This is true regardless of whether you trade equity futures, index options, commodity futures, or currency derivatives.

This classification matters because it determines which ITR form you file, which tax rate applies, and whether you can deduct trading expenses.

2. Tax rates for F&O income (FY 2025-26)

F&O income is added to your total income and taxed at your slab rate. Under the new tax regime (default for FY 2025-26), the slabs are:

Add 4% Health and Education Cess on the tax amount. Section 87A rebate applies (up to ₹60,000 rebate if total income ≤ ₹12L), but it applies only to slab-rate tax — not to STCG or LTCG taxes on top of that.

3. How to calculate F&O turnover

F&O turnover is not the same as transaction value. Per ICAI (Institute of Chartered Accountants of India) guidance, turnover for derivatives is calculated as:

Note that the premium received on options sold is also included in turnover calculations under some CA interpretations. Consult your CA for the exact method applicable to your portfolio.

4. Tax audit — do you need one?

This is the question most traders worry about. The short answer for FY 2025-26: most active traders with digital transactions do not need a tax audit.

5. Expenses you can deduct

One major advantage of F&O income being classified as business income is that you can deduct business-related expenses under Section 37 of the IT Act. Deductions reduce your taxable F&O income directly.

Fully deductible trading costs:

• STT (Securities Transaction Tax) on F&O trades
• Brokerage paid to your broker
• Exchange transaction charges (NSE/BSE/MCX)
• GST on brokerage
• Stamp duty on trades
• SEBI turnover fees
• DP / demat charges

Other deductible business expenses:

• Internet and telephone charges (proportionate to trading use)
• Subscription to trading software, charting tools, market data feeds
• Advisory fees paid to registered investment advisors
• Margin interest paid on trading margin
• Depreciation on computers/hardware used for trading

6. Which ITR form to file

F&O traders must file ITR-3. This is non-negotiable — ITR-1 (Sahaj) and ITR-2 do not have provisions for business income and cannot be used if you have any F&O trades during the year, even if you made a loss.

ITR-3 requires you to fill:

• Schedule BP — Business and Professional income (your F&O net profit/loss)
• Schedule P&L — Profit and Loss account with turnover, expenses, and net income
• Schedule BS — Balance sheet (simplified for traders)
• Schedule CG — Capital Gains (for equity STCG/LTCG if any)
• Schedule CYLA/BFLA — Current year and brought-forward loss set-off

7. Advance tax deadlines for F&O traders

If your total estimated tax liability for the year exceeds ₹10,000, you must pay advance tax in four installments. Missing a deadline attracts 1% interest per month under Section 234C.

The tricky part for F&O traders: your income can vary wildly quarter to quarter. A good practice is to estimate your tax after each quarter based on year-to-date P&L and pay the cumulative percentage due.

8. Loss carry-forward rules

F&O losses (non-speculative business losses) can be carried forward for 8 assessment years. In future years, you can set them off against:

• Non-speculative business income (F&O profit in future years)
• Short-Term Capital Gains (STCG) from equity
• Long-Term Capital Gains (LTCG) from equity
• Other income sources (salary excluded)

9. Worked example

Let's trace through a realistic scenario: Rahul is a salaried software engineer who also trades F&O.

Rahul should have paid advance tax installments through the year to avoid 234C interest. He also has ₹22,000 of deductible trading charges that reduce his tax by approximately ₹3,300 (at his ~15% marginal rate).
