Most investors know they must pay capital gains tax. Far fewer know exactly which ITR form to use, which schedule to fill, and how to report F&O losses. Getting this wrong can trigger notices from the Income Tax Department.
1. Which ITR Form for Market Income?
| Your Situation | Correct ITR Form |
|---|---|
| Salaried + only capital gains from stocks/MFs | ITR-2 |
| F&O trading income (treated as business income) | ITR-3 |
| Only salaried with no capital gains | ITR-1 (Sahaj) |
| F&O trader who also runs a business | ITR-3 |
Key rule: Any F&O income or loss automatically requires ITR-3, regardless of how small the trading activity was. Using ITR-1 or ITR-2 when you have F&O is an error.
2. Documents Required Before Filing
- Form 16 — from employer (TDS deducted on salary)
- Tax P&L report from your broker (Zerodha, Groww, HDFC Securities) — shows every trade with gain/loss calculation
- Capital Gains Statement from MF portal — download from CAMS, KFintech, or MF Central
- Form 26AS — from income tax portal (shows all TDS deducted against your PAN)
- AIS (Annual Information Statement) — newer comprehensive tax statement from IT portal showing all financial transactions
- Form 16A — for TDS on dividends, FD interest, etc.
3. Step-by-Step: Filing ITR-2 for Capital Gains Tax in India
Step 1: Log in at incometax.gov.in with your PAN + Aadhaar-linked mobile OTP.
Step 2: Go to “File Income Tax Return” → Select Assessment Year (FY2025-26 = AY 2026-27).
Step 3: Select ITR-2 (since you have capital gains).
Step 4: Prefilled data appears from Form 26AS and AIS. Verify all entries carefully — brokers report to IT Department, so the department already knows your trades.
Step 5: Fill Schedule CG (Capital Gains):
- B1: LTCG on listed equity shares/equity MFs (rate: 12.5%)
- B2: STCG on listed equity shares/equity MFs (rate: 20%)
- B3: STCG on debt MFs / other assets (slab rate)
- Ensure the exemption of ₹1,25,000 is applied to LTCG in B1
Step 6: Fill Schedule OS (Other Sources) for dividend income, FD interest, etc.
Step 7: Apply deductions — Section 80C (PF, PPF, ELSS, tuition fees), 80CCD(1B) (NPS), 80D (health insurance premium), Section 24 (home loan interest, up to ₹2 lakh).
Step 8: Choose old or new tax regime. Compare both before selecting.
Step 9: e-Verify using Aadhaar OTP (fastest), net banking, or DSC. ITR is not complete until e-verified.
4. F&O Income Reporting (ITR-3)
F&O income is business income, not capital gains. This has major implications:
- Turnover calculation for F&O: Sum of absolute value of all profits + losses (every contract, every leg). If F&O turnover exceeds ₹2 crore (for cash settlement), audit is compulsory.
- F&O losses can be set off against other business income in the same year.
- F&O losses can be carried forward for 8 years but only against business income.
- Expenses are deductible: Brokerage, internet, equipment, subscription for market data are deductible business expenses in ITR-3.
Audit requirement: If F&O turnover > ₹1 crore (lower limit), you need a tax audit (Section 44AB) if your net profit is less than 6% of turnover.
5. Common Mistakes That Trigger IT Notices
Mistake 1: Not reporting capital gains because “TDS was already deducted.” TDS on equity is not deducted by brokers — you must self-report and pay self-assessment tax if any.
Mistake 2: Using ITR-1 when you have F&O or more than one house property.
Mistake 3: Not matching figures with AIS. If your ITR figures differ significantly from AIS, expect a notice.
Mistake 4: Not filing on time. Capital loss carry-forward is only available if ITR is filed before the due date (typically July 31 for non-audit cases).
Mistake 5: Ignoring dividend income. Dividends above ₹5,000 from any company have TDS at 10% deducted. But the full dividend is taxable at slab rate and must be reported in Schedule OS.
Summary Checklist: The ITR Filing Checklist for Investors
| Step | Action |
|---|---|
| Identify correct ITR form | ITR-2 (capital gains) or ITR-3 (F&O) |
| Collect broker P&L report | Download from Zerodha Console / broker portal |
| Download MF capital gains statement | CAMS / KFintech |
| Match with Form 26AS and AIS | Ensure no discrepancies |
| Apply all eligible deductions | 80C, 80CCD(1B), 80D, 24(b) |
| Compare old vs new tax regime | Choose lower tax option |
| File and e-verify before July 31 | Not e-verified = not filed |
The Smart Friend’s Verdict
Tax filing for investors is tedious but not complicated once you have the right form and the right documents. The 3 hours spent filing correctly are worth it — incorrect filing can result in notices, penalties, and the loss of capital loss carry-forward rights that could save lakhs over 8 years.
Get your broker’s Tax P&L, download the AIS, and use a qualified CA for the first year if F&O is involved. Thereafter, it becomes routine.
