A mutual-fund SIP creates many separate purchase lots. When units are redeemed, the tax working must identify which lots were sold, their acquisition dates and costs, the fund category, and the resulting holding period. A single bank credit or AIS entry cannot supply all of those facts.
The return should be prepared from the transaction-level capital-gains report and checked against the consolidated account statement, AMC records, and sale proceeds.
Separate investment activity from taxable disposals
Monthly SIP purchases are not capital gains. A taxable disposal question generally arises when units are redeemed, switched, sold, or otherwise transferred. A switch from one scheme to another can involve a redemption even when no cash reaches the bank account.
List every disposal during FY 2025-26. Include redemptions used for systematic withdrawal plans, switches, and any transaction reported by an AMC or registrar as a sale. Dividend or income-distribution entries are not the same as redemption gains and need their own income treatment.
Identify the fund category and transaction date
Tax treatment can differ for equity-oriented funds, specified mutual funds, debt-oriented holdings, international funds, gold funds, and other categories. It can also depend on acquisition and transfer dates because the capital-gains rules have changed over time.
Do not classify a fund solely from its marketing name. Use the scheme details and the capital-gains statement, then confirm the applicable treatment for the actual transaction dates. Where the statement’s category or holding-period result is unclear, pause the computation instead of forcing every redemption into the same rate.
Rebuild the gain lot by lot
For each redemption, retain:
| Required fact | Primary record | Review question |
|---|---|---|
| Units and redemption date | AMC or registrar transaction statement | Does it include switches and systematic withdrawals? |
| Purchase lots and acquisition dates | Consolidated account statement or detailed ledger | Which lots were matched to the redemption? |
| Cost and gain calculation | Capital-gains report | Does the method reflect the correct fund category and dates? |
| Sale proceeds | Redemption confirmation and bank statement | Does the net credit agree after any deductions or charges? |
| Third-party reporting | AIS | Is an entry missing, duplicated, or shown under a different value? |
When the AMC capital-gains report and consolidated statement disagree, identify the specific folio and transaction rather than adjusting a total figure without explanation.
Use AIS as a mismatch signal
AIS may report mutual-fund transactions, but it may not provide the complete lot-level cost and holding-period calculation required for the return. Compare AIS with the AMC or registrar records. Give AIS feedback where appropriate and retain the statement that supports the amount ultimately used.
The Income Tax Department’s AIS guidance explains the information view and feedback process. A missing AIS item does not remove a disposal that is established by the investor’s own records.
Choose the return form after identifying all gains
Capital gains can make ITR-1 and ITR-4 unsuitable. An investor with salary plus mutual-fund gains may need ITR-2, while business or trading facts can point to a different return. Use the ITR form selector only after the gain and the rest of the taxpayer’s income are known.
The capital gains calculator can help organise an estimate, but it does not replace the scheme classification, transaction history, exemptions, set-off rules, or notified return schedules.
Worked example: several SIP lots, one redemption
Suppose an investor bought units monthly for three years and redeemed part of the holding in December 2025. The redemption may draw from several acquisition lots. Some lots may have a different holding period from others, so the full sale proceeds cannot automatically be treated as one short-term or long-term item.
The detailed capital-gains report should show the matched lots. Compare those lots with the consolidated account statement and confirm that the redemption proceeds agree with the bank credit. If the report omits an older purchase or corporate action, correct the source data before relying on the calculated gain.
Filing file to retain
Keep the consolidated account statement, AMC or registrar transaction ledger, capital-gains report, redemption confirmations, bank statement, AIS download, computation, filed return, and e-verification acknowledgement. Where a loss is reported, confirm the filing deadline and carry-forward treatment from the actual return facts.
