AIS and Form 26AS Checks for Traders Before Filing
Most trader filing errors are visible before the return is submitted. AIS, TIS, Form 26AS, broker P&L, trade ledger and bank statements often tell different parts of the same story. The filing risk comes from using only one of them and ignoring the rest.
Before filing ITR-3 for AY 2026-27, traders should complete a reconciliation checklist. This is especially important for salaried traders, F&O loss cases, intraday activity, high-value delivery sales, dividend income and TDS credits.
AIS vs Form 26AS vs Broker P&L
| Document | What it helps verify | Trader risk if ignored |
|---|---|---|
| AIS/TIS | Reported transactions, interest, dividend, SFT and other information | Mismatch notices or missing income |
| Form 26AS | TDS, tax credits and tax payments | Wrong refund or demand |
| Broker P&L | Trading profit/loss and capital gains | Incorrect income classification |
| Trade ledger | Detailed trades, charges and fund flows | Unsupported turnover or expense claims |
| Bank statement | Transfers, interest and unexplained credits | Reconciliation gaps |
Mismatch Table
| Mismatch | Possible reason | Action before filing |
|---|---|---|
| AIS shows sale but broker gain is different | AIS may show gross transaction value, broker computes gain after cost | Use broker computation, keep reconciliation |
| Dividend appears in AIS but not in computation | Dividend credited separately or reinvested | Add dividend under correct head |
| TDS missing in return | Form 26AS not matched | Import or manually verify tax credits |
| High-value SFT entry appears | Broker/reporter submitted transaction data | Check whether return explains related income |
| F&O not visible clearly in AIS | AIS may not provide full profit/loss computation | Use broker P&L and ledger for business computation |
Broker P&L Reconciliation
- Download capital gains statement and business P&L separately.
- Separate delivery, intraday and F&O transactions.
- Match opening holdings and closing holdings where delivery trades exist.
- Check charges, brokerage and taxes included in the broker report.
- Compare dividend and interest with AIS.
- Keep a final tax computation PDF or worksheet with the filed return.
TDS and Tax Credit Checks
Even if trading income has no TDS, a trader may have salary TDS, bank TDS, dividend TDS, professional receipts TDS, advance tax or self-assessment tax. A return filed with missing tax credits can create unnecessary demand or reduce refund.
- Match Form 16 TDS with Form 26AS.
- Match bank TDS with certificates and 26AS.
- Check advance tax and self-assessment tax challans.
- Use the correct assessment year while verifying challans.
- Confirm refund bank account is validated.
Foreign Asset Flag
Resident taxpayers with foreign trading accounts, foreign shares, foreign bank accounts or overseas broker balances should review foreign asset and foreign income schedules before filing. This is not only a trading-income question; it can become a disclosure question.
Pre-Filing Checklist
- AIS downloaded and reviewed.
- TIS checked for summary amounts.
- Form 26AS matched with TDS and challans.
- Broker P&L downloaded for the full financial year.
- Intraday and F&O turnover computed.
- Capital gains checked separately from business trading.
- Expenses supported by invoices or clear records.
- Regime choice and Form 10-IEA reviewed where business income exists.
Common Mistakes

- Treating AIS transaction value as taxable gain.
- Missing dividend income because it is small.
- Claiming tax credit that is not visible in Form 26AS.
- Not keeping a reconciliation for mismatches.
