AIS for Capital Gains: Essential ITR Safeguards for Investors in 2026

.AIS for Capital Gains: The Investor’s Precision Guide to a Flawless ITR in 2026

AIS for Capital Gains is a valuable starting point while preparing an Income Tax Return, but it should not be treated as the final capital-gains computation.

The Annual Information Statement may display transactions reported by stock exchanges, depositories, mutual funds, banks and other reporting entities. However, the taxpayer remains responsible for reporting complete and accurate income—even where a transaction is missing, duplicated or incorrectly reflected in AIS.

Before filing the ITR for Assessment Year 2026–27, investors should independently calculate gains and losses using broker tax reports, contract notes, mutual fund statements, demat records and supporting documents. The result should then be reconciled with AIS and the Taxpayer Information Summary.

AY 2026–27 relates to income earned during Financial Year 2025–26 and continues to be governed by the Income-tax Act, 1961, notwithstanding the commencement of the Income-tax Act, 2025 from 1 April 2026.

What Is the Annual Information Statement?

The Annual Information Statement is a consolidated view of financial information available with the Income Tax Department in relation to a taxpayer.

It may contain:

• TDS and TCS information;

• specified financial transactions;

• tax payments;

• refunds;

• interest and dividend information;

• securities transactions;

• mutual fund transactions;

• foreign remittances; and

• other information received from reporting entities.

AIS also allows taxpayers to submit feedback where an entry is incorrect, duplicated, related to another person or otherwise requires correction. The related Taxpayer Information Summary presents information category-wise after system processing and consideration of taxpayer feedback.

However, the Income Tax Department expressly clarifies that AIS contains only the information presently available with it. Other transactions may not be displayed, and taxpayers are expected to independently report complete and accurate information in their returns.

This makes AIS a reconciliation tool, not a substitute for books, investment statements or an independent tax computation.

Is AIS for Capital Gains Enough to File the ITR?

No. Relying entirely on AIS for Capital Gains can result in incorrect reporting.

AIS may help identify sales and redemptions reported against a PAN. However, the final capital gain depends upon several additional factors, including:

• correct cost of acquisition;

• date of purchase;

• date of transfer;

• period of holding;

• corporate actions;

• grandfathering provisions;

• transfer-related expenses;

• treatment of gifted or inherited investments;

• classification of the security or mutual fund;

• earlier-year capital losses; and

• whether the activity represents investment or business trading.

The Income Tax Department’s ITR-2 guidance itself advises taxpayers having gains from shares or securities to obtain a summary or profit-and-loss statement for capital-gains computation.

Accordingly, neither AIS nor a pre-filled ITR should be accepted without verification.

Why Can AIS Differ from the Actual Capital Gain?

1. AIS May Primarily Reflect Sale Information

Reporting entities may communicate the sale value, redemption value, quantity or transaction date. The cost displayed may be missing, incomplete or based on limited data available to the reporting entity.

Taxable capital gain is not simply the sale consideration appearing in AIS. It must generally be computed after deducting the correct cost and eligible expenditure connected with the transfer.

2. Corporate Actions Can Change the Cost

Stock splits, bonus shares, rights issues, mergers, demergers and consolidations can change the number of securities held and the manner in which their cost is allocated.

The broker’s report may also require adjustment where the transaction history originated with another broker or before the current demat account was opened.

3. Older Investments May Require Special Computation

Listed equity shares and equity-oriented fund units acquired before 1 February 2018 may be subject to the grandfathering mechanism while calculating long-term capital gains.

The ITR-2 reporting framework requires scrip-wise information for qualifying securities acquired on or before 31 January 2018.

A simple AIS sale value cannot independently perform this calculation.

4. Multiple Brokers Can Create Incomplete Results

An investor may have:

• two or more demat accounts;

• investments through separate brokers;

• direct mutual fund investments;

• regular mutual fund plans;

• employee stock holdings;

• inherited securities; or

• investments transferred from another account.

A report downloaded from one broker will not provide a complete picture of the taxpayer’s investments.

5. AIS Can Contain Duplicate or Incorrect Entries

An entry may be duplicated because information has been received through more than one reporting channel. There may also be an incorrect PAN, transaction value, date or classification.

Taxpayers can submit feedback on AIS information, but they should retain evidence supporting the correction.

Seven Essential Checks Before Reporting Stock and Mutual Fund Gains

1. Download the Broker’s Tax Profit-and-Loss Statement

Investors should obtain a tax P&L or capital-gains report from every broker used during Financial Year 2025–26.

The report should ideally show:

• name of security;

• quantity sold;

• purchase date;

• sale date;

• purchase value;

• sale value;

• holding period;

• short-term or long-term classification;

• brokerage and other charges; and

• resulting gain or loss.

The report should be matched with contract notes and the demat transaction statement where material differences arise.

A broker report is more detailed than AIS, but it is not automatically final. It may still require adjustment for transferred holdings, corporate actions, grandfathering or incorrect opening costs.

2. Obtain Separate Mutual Fund Capital-Gains Statements

A bank statement may show only the amount received on redemption. It does not establish which mutual fund units were redeemed, their acquisition dates or their tax classification.

Investors should obtain scheme-wise capital-gains statements from the relevant asset management companies or mutual fund registrars.

The statement should be checked for:

• SIP purchases;

• switches between schemes;

• systematic withdrawals;

• reinvestment transactions;

• growth and income-distribution options;

• exit loads;

• units transferred between folios; and

• direct and regular plans.

A mutual fund switch is generally treated as a redemption from one scheme and purchase into another. It should not be ignored merely because no amount was transferred to the investor’s bank account.

3. Apply the Correct FIFO Method

Where securities are held in dematerialised form, the First-In-First-Out method is used to identify the securities treated as sold and determine the relevant holding period and cost.

This means the securities entering the demat account first are generally considered to have been sold first.

An investor cannot ordinarily select the highest-cost purchase lot merely to reduce the capital gain where FIFO applies.

This becomes important where the same share was purchased:

• on several dates;

• at different prices;

• through systematic investments; or

• before and after 31 January 2018.

4. Classify the Investment Correctly

Different investments do not receive identical tax treatment.

For Financial Year 2025–26, qualifying short-term capital gains on STT-paid listed equity shares and equity-oriented mutual fund units are generally taxable at 20%. Qualifying long-term gains under Section 112A are generally taxable at 12.5% on the aggregate amount exceeding ₹1.25 lakh, subject to the applicable conditions.

The concessional provisions depend on factors such as:

• nature of security;

• period of holding;

• payment of securities transaction tax;

• mode of transfer; and

• whether the asset is an equity-oriented fund.

The broker’s description of a transaction should therefore be checked against the statutory classification.

5. Do Not Treat Every Mutual Fund as an Equity Fund

The phrase “mutual fund” covers several categories, including:

• equity-oriented funds;

• debt-oriented funds;

• gold funds;

• international funds;

• hybrid funds;

• exchange-traded funds; and

• fund-of-funds schemes.

For AY 2026–27, Section 50AA treats qualifying units of specified mutual funds acquired on or after 1 April 2023 as short-term capital assets, irrespective of the actual period of holding.

From AY 2026–27, a specified mutual fund broadly includes a fund investing more than 65% of its proceeds in debt and money-market instruments, as well as certain funds investing at least 65% in units of such debt-heavy funds. Gains covered by Section 50AA are treated as short-term gains and taxed at the taxpayer’s applicable rate.

Investors should therefore not assume that every mutual fund held for more than one year qualifies for the 12.5% long-term capital-gains rate.

6. Deduct Only Eligible Transfer Expenses

Capital gains are generally calculated by reducing the cost of acquisition and expenditure incurred wholly and exclusively in connection with the transfer from the sale consideration.

Brokerage and certain transaction-related expenses may be considered where legally eligible and properly supported.

However, Securities Transaction Tax is specifically not deductible while computing capital gains.

A broker report may contain several charges, such as:

• brokerage;

• exchange transaction charges;

• GST;

• stamp duty;

• depository charges; and

• STT.

Taxpayers should not mechanically deduct the total of all charges without examining their nature and legal treatment.

7. Reconcile Losses Before Filing

Capital losses can materially affect the final tax liability.

A short-term capital loss can generally be set off against both short-term and long-term capital gains. A long-term capital loss can generally be set off only against long-term capital gains.

Unabsorbed capital losses may ordinarily be carried forward for eight assessment years, provided the return of loss is furnished within the applicable due date under Section 139(1).

AIS may show sale transactions, but it does not automatically ensure that:

• current-year losses are correctly adjusted;

• earlier-year losses are brought forward;

• losses are placed in the correct tax basket; or

• Schedule CFL is properly completed.

Practical Example: Why AIS May Show the Wrong Gain

Suppose Ms Nisha purchased 500 shares of an Indian listed company in three batches:

She sells 250 shares in December 2025 at ₹650 per share.

AIS may reflect the sale consideration of ₹1,62,500. However, this is not the taxable gain.

Under FIFO, the 250 shares treated as sold would generally comprise:

• 200 shares purchased at ₹300; and

• 50 shares purchased at ₹420.

The cost would therefore be calculated using those purchase lots, not the latest market price or the cost of the August 2024 purchase.

The holding period of each lot must also be examined separately. Eligible transfer expenses must be adjusted, while STT cannot be deducted.

This example shows why sale information appearing in AIS cannot replace a transaction-wise computation.

Another Example: Debt Mutual Fund Held for Two Years

Mr Arjun invested ₹5 lakh in a debt-oriented mutual fund in June 2023 and redeemed it for ₹5.80 lakh in September 2025.

He may assume that the ₹80,000 gain is long-term because the units were held for more than two years.

However, if the fund falls within Section 50AA, the gain may be deemed short-term because the units were acquired after 1 April 2023. It would then be taxed at the applicable rate rather than the concessional equity-oriented fund rate.

AIS may show the redemption but may not adequately explain why the gain requires this particular statutory treatment.

Which ITR Form Should Investors Use?

ITR-1

For AY 2026–27, an otherwise eligible resident individual may use ITR-1 where long-term capital gains under Section 112A do not exceed ₹1.25 lakh.

ITR-1 cannot be used where the taxpayer has:

• short-term capital gains;

• long-term capital gains under Section 112A exceeding ₹1.25 lakh;

• business or professional income; or

• other disqualifying income or circumstances.

ITR-2

ITR-2 is generally applicable to an individual or HUF having capital gains but no income chargeable under the head “Profits and Gains of Business or Profession.”

Schedule CG is used for reporting different categories of capital gains and losses. Schedule 112A is relevant for qualifying listed equity shares, equity-oriented fund units and business trust units.

ITR-3

ITR-3 is generally applicable where the individual or HUF has business or professional income in addition to capital gains.

Frequent share trading, intraday transactions, derivatives and securities held as stock-in-trade may require a business-income analysis. The character of the activity depends on the taxpayer’s facts, accounting treatment, intention, volume and overall conduct. CBDT has recognised that shares may be held as capital assets, stock-in-trade or both.

What Is the ITR Due Date for AY 2026–27?

Taxpayers should verify the due date applicable to their return form and category rather than relying on a single date quoted in a news report.

The Income Tax Department’s transition guidance refers to 31 July 2026 or 31 August 2026 for different non-audit categories. Its ITR-4 guidance specifically states that the AY 2026–27 due date for ITR-4 is 31 August 2026. Audit and transfer-pricing cases have separate timelines.

A taxpayer reporting ordinary investment capital gains through ITR-2 should check the current portal guidance and the statutory due date applicable to that taxpayer before filing.

Timely filing is especially important where capital losses are to be carried forward.
