AIS is a reporting signal, not a capital-gains ledger. If a sale is absent from AIS, the transaction can still belong in the AY 2026-27 return. Build the gain or loss from contract notes, broker reports, ownership records, acquisition cost, and corporate-action history.
Identify exactly what AIS omitted
Start with a sale inventory for FY 2025-26. Separate listed shares, mutual funds, property, unlisted shares, bonds, and other capital assets because their cost, holding period, rate, and return schedules can differ.
| Sale evidence | Why it matters |
|---|---|
| Contract note or registered sale document | Establishes transfer date and consideration |
| Broker tradebook or fund statement | Shows quantity, price, charges, and transaction history |
| Demat or ownership record | Confirms holding and corporate actions |
| Purchase and improvement evidence | Supports cost and eligible adjustments |
| Bank statement | Traces material receipts and payments |
Compare this inventory with AIS and record which item is missing. Do not omit a supported sale merely to make the return agree with an incomplete AIS download.
Calculate the gain independently
Determine the acquisition date, transfer date, supported cost, eligible expenses, and any special rule relevant to the asset. Bonus issues, splits, mergers, inherited assets, older purchases, and transfers between brokers frequently require more than a default broker report.
Use the capital gains calculator for an estimate and the capital gains import tool to organise broker files. Inspect every exception before using the output in a return.
Leave an evidence trail for the difference
Download the AIS version used for review, give feedback where appropriate, and retain a reconciliation note linking the missing entry to the filed schedule. The Income Tax Department's AIS guidance explains the information statement but does not replace transaction evidence.
Select the return form from the full taxpayer profile. Capital gains commonly affect ITR eligibility, and business trading, foreign assets, or carried-forward losses can change the route again. Review the ITR-2 checklist before submission.
Retain the sale inventory, acquisition evidence, calculations, AIS download and feedback, filed schedules, and acknowledgement.
Example: a broker sale appears nowhere in AIS
Assume a demat statement and contract note show a listed-share sale, but the AIS download has no corresponding entry. The supported sale still needs a holding-period and gain calculation. Add it to the sale inventory, preserve the broker and demat trail, and note that the AIS omission was reviewed. Do not create an artificial AIS value or postpone the transaction indefinitely without checking the filing deadline.
Where broker data is incomplete, the stock-investor LTCG and STCG guide explains corporate-action and lot-history checks. If the sale changes the return from a simple salary form, review which ITR form applies to salary plus capital gains. A material unsupported cost, inherited asset, or disputed ownership fact should be resolved before the return is submitted.
The final working should identify every sale included despite the AIS omission and the exact evidence used for cost, date, and consideration.

Reconstruct the disposal without waiting for AIS
Create a transaction row for every sale or redemption omitted from AIS. Capture the asset, broker or registrar, acquisition date and cost, transfer date, consideration, charges, quantity, holding period, and evidence used. Corporate actions, transferred broker accounts, inherited assets, and systematic withdrawals may require an additional cost or ownership trail before the gain can be calculated.
Reconcile the completed calculation with the broker statement, contract notes, demat movement, bank receipt, and any tax statement that does exist. Note that AIS is incomplete and retain the downloaded version used for review; do not suppress a supported gain or loss merely because the information statement has no matching entry. The final working should explain the return schedule and treatment chosen for each disposal and identify any unresolved cost, ownership, or classification question before submission. <!-- ay-route-specific-depth:end -->
