Capital gains computation mismatches arise when figures reported in Schedule CG of the Income Tax Return do not align with broker-reported data reflected in AIS or Form 26AS. These gaps are increasingly flagged by the Income Tax Department through automated systems, often leading to notices under Sections 133(6) or 142(1). Errors usually stem from incorrect cost calculations, holding period classification, missed transactions, or improper exemption claims. With brokers reporting transaction-level data directly to tax authorities, reconciliation has become critical. Platforms like TaxBuddy now play a key role by aligning broker data with return filings to prevent and resolve such notices efficiently.

What Is a Capital Gains Computation Mismatch
A capital gains computation mismatch occurs when the capital gains reported in Schedule CG of the Income Tax Return do not align with transaction data reflected in the Annual Information Statement or Form 26AS. These differences usually arise in equity shares, mutual funds, bonds, or property transactions. Since brokers and registrars report transaction-level data directly to the Income Tax Department, even small errors in cost, quantity, or dates can trigger automated scrutiny. Such mismatches are now identified digitally, without manual intervention, making accurate computation and reconciliation essential for compliant tax filing.
Why Broker Data in AIS Triggers Income Tax Notices
Broker data plays a central role in the Income Tax Department’s risk assessment process because it is treated as third-party information reported independently of the taxpayer. Brokers submit Statements of Financial Transactions against each PAN, which are then reflected in the Annual Information Statement. This data typically captures transaction-level details such as the date of purchase, date of sale, quantity of securities, total sale value, and in many cases the gross proceeds received from the transaction. Since this information is reported directly by intermediaries regulated by exchanges and depositories, it is considered a reliable reference point for verification.
When an Income Tax Return is filed, the department’s systems automatically compare the capital gains declared in Schedule CG with the broker-reported data available in AIS. Even a small difference, such as a variation in sale value, missing transaction, or mismatch in dates, can trigger a system flag. These flags are not created through manual review. They are generated by automated rules designed to identify patterns of possible underreporting, incorrect classification of gains, or omission of taxable transactions.
Another common trigger arises because broker data often reflects gross transaction values without considering tax adjustments. For example, the AIS may show the full sale consideration of a security, while the ITR reflects net capital gains after deducting cost of acquisition, applying indexation, or adjusting for exemptions. If the return does not clearly reconcile these differences, the system may treat the variation as a potential mismatch requiring clarification.
Classification errors also play a role. Broker data does not distinguish between short-term and long-term gains based on tax law interpretations. If the holding period is calculated incorrectly in the return, or if equity transactions eligible for concessional treatment are misreported, the automated comparison highlights the inconsistency. Similarly, intraday trades or partial sales that are overlooked or grouped incorrectly can appear as unreported income when matched against broker submissions.
As a result, income tax notices triggered by AIS mismatches are essentially verification requests. They are issued to confirm whether the difference arises from a genuine reporting error, a timing issue, or a valid tax adjustment. Providing clear explanations, accurate recalculations, and supporting documents usually resolves such notices without further action, but ignoring or mismanaging them can lead to prolonged scrutiny and additional compliance burden.
Common Errors in STCG and LTCG Reporting
Several recurring errors lead to capital gains mismatches. Incorrect holding period calculation often results in short-term gains being reported as long-term or vice versa. Cost of acquisition may be understated or overstated, especially in cases of multiple purchases, bonus shares, or rights issues. Indexation benefits are sometimes applied incorrectly. Missed intraday trades or partial sale reporting also contribute to discrepancies. These errors, though unintentional, are easily flagged when broker data is compared with return filings.
How Capital Gains Are Verified by the Income Tax Department
The verification process is largely automated. The department compares Schedule CG figures with AIS and Transaction Information Summary data. Scrip-wise matching is carried out to check quantities, dates, and sale values. Holding periods are validated using transaction dates, and exemptions claimed under capital gains provisions are cross-verified. If inconsistencies are detected, an online notice is issued asking for clarification, revised computation, or supporting documents.
Sections Under Which Capital Gains Notices Are Issued
Capital gains-related notices are commonly issued under Section 133(6) for information verification or Section 142(1) seeking explanation or additional details. In some cases, adjustments may also reflect in intimation under Section 143(1). These sections empower the department to request transaction details, computation workings, and documentary proof to ensure correct tax reporting under the Income Tax Act, 1961.
How Broker-Reported Transactions Differ From ITR Data
Broker-reported data often reflects gross transaction values without accounting for deductions, exemptions, or adjustments claimed in the ITR. For example, brokers may report total sale consideration without factoring in indexed cost, grandfathering provisions, or exemptions under capital gains sections. Differences also arise due to FIFO application, consolidation of multiple transactions, or timing differences in reporting. Without reconciliation, these differences appear as mismatches to tax authorities.
How TaxBuddy Uses Broker Data for Capital Gains Reconciliation
TaxBuddy integrates broker statements and PAN-linked transaction data to perform detailed reconciliation. Transactions are matched at a scrip level to verify quantities, dates, and prices. The platform recalculates gains using correct cost methods and applicable tax provisions. Any mismatch is flagged early, allowing corrections before filing or structured responses if a notice is received. This approach ensures that reported capital gains align with broker data while remaining compliant with tax laws.
Step-by-Step Process to Handle Capital Gains Mismatch Notices
The process begins by accessing the notice on the income tax portal and reviewing the specific mismatch highlighted. AIS and broker statements are then downloaded for verification. Capital gains are recalculated using accurate transaction data. Supporting documents such as contract notes are compiled. A response is filed online with revised workings or explanations. Platforms like TaxBuddy streamline this process by auto-populating corrected data and guiding compliant responses.
When to File a Revised Return or ITR-U for Capital Gains Errors
If an error is identified before the revision deadline, a revised return under Section 139(5) is the preferred option. This allows correction without additional penalties. When the revision window has closed, ITR-U can be filed to disclose missed or incorrect capital gains, subject to additional tax and interest. Choosing the correct route depends on timelines, notice stage, and the nature of the mismatch.
Penalties and Consequences of Unresolved Capital Gains Mismatch
Ignoring or incorrectly responding to capital gains mismatch notices can lead to tax demands, interest under Sections 234A, 234B, and 234C, and penalties for underreporting under Section 270A. In severe cases, scrutiny assessments may follow. Timely reconciliation and accurate correction significantly reduce the risk of such outcomes.
How Automated Reconciliation Reduces Notice Risk
Automated reconciliation aligns broker data with return filings before submission. It reduces human error, ensures correct application of tax rules, and highlights discrepancies early. This proactive approach minimizes the likelihood of notices and speeds up resolution when they do arise. Automation also improves documentation accuracy, which is critical during departmental verification.
Choosing the Right Support for Capital Gains Notice Compliance
Handling capital gains notices requires both technical accuracy and procedural compliance. While simple cases may be resolved independently, complex portfolios with multiple brokers or exemptions benefit from structured platforms. Solutions that combine data integration, tax logic, and expert oversight offer better accuracy and lower compliance risk, making platforms like TaxBuddy a practical choice.
Conclusion
Capital gains computation mismatches have become a common trigger for income tax notices due to extensive broker data reporting and automated verification systems. Accurate reconciliation, timely correction, and proper documentation are essential to avoid penalties and prolonged scrutiny. Platforms that integrate broker data and tax compliance workflows simplify this process significantly.

FAQs
Q1. Does TaxBuddy offer both self-filing and expert-assisted plans for ITR filing, or only expert-assisted options?
TaxBuddy offers both self-filing and expert-assisted ITR filing options. The self-filing option is suitable for individuals with straightforward income sources and simple capital gains, where the system automatically reads data, reconciles transactions, and flags inconsistencies. Expert-assisted plans are designed for cases involving multiple brokers, complex capital gains, exemption claims, or income tax notices. These plans include professional review, reconciliation of AIS and broker data, and guided notice responses to ensure accuracy and compliance.
Q2. Which is the best site to file ITR?
The Income Tax Department’s official e-filing portal is the primary and mandatory platform for submitting income tax returns. However, many taxpayers prefer using tax filing platforms like TaxBuddy because they offer a guided filing experience, automated data reconciliation, and built-in checks for mismatches. Such platforms reduce errors, especially in capital gains reporting, and provide support when notices or corrections are required.
Q3. Where to file an income tax return?
Income tax returns can be filed directly on the government’s e-filing portal using PAN-based login credentials. Alternatively, authorized tax filing platforms like TaxBuddy can be used to prepare, validate, and submit returns through the same portal. These platforms act as an interface that simplifies data entry, verification, and compliance while ensuring the return is ultimately filed with the Income Tax Department.
Q4. What is AIS in relation to capital gains?
The Annual Information Statement is a consolidated record of financial transactions linked to a PAN. For capital gains, AIS includes buy and sell transactions reported by brokers, registrars, and depositories. This data is used by the Income Tax Department to verify whether capital gains reported in the ITR match third-party disclosures. Any inconsistency between AIS data and Schedule CG figures may trigger a notice.
Q5. Can a capital gains mismatch be corrected without a notice?
Yes, capital gains mismatches can be corrected proactively if identified before a notice is issued. This is done by filing a revised return within the permitted timeline. Correcting errors early helps avoid scrutiny, interest, and penalties. Reviewing AIS and broker statements before filing or shortly after submission significantly reduces the risk of receiving a mismatch notice.
Q6. Are intraday trades also reported in AIS?
Intraday and derivative trades may appear in AIS depending on how brokers report the transactions. While these trades do not result in capital gains, incorrect classification or omission in the return can still cause discrepancies. It is important to reconcile trading statements carefully and ensure that intraday income is correctly reported under the appropriate head of income.
Q7. Is indexation applicable to all long-term assets?
Indexation is not applicable to all long-term assets. It is allowed only for specified assets under the old tax regime, such as certain types of debt instruments and immovable property, subject to conditions. Equity shares and equity-oriented mutual funds are generally taxed without indexation. Understanding asset classification and regime applicability is crucial before applying indexation benefits.
Q8. What documents are needed to respond to a capital gains notice?
Responding to a capital gains notice typically requires broker contract notes, detailed transaction statements, proof of acquisition cost, sale consideration, and a revised capital gains computation. In cases involving exemptions, supporting documents such as purchase agreements or investment proofs may also be required. Accurate documentation helps establish the correctness of reported income.
Q9. Can capital gains notices be handled online?
Most capital gains-related notices can be handled entirely online through the income tax e-filing portal. Responses, explanations, and supporting documents can be uploaded digitally within the prescribed timeline. Online handling reduces physical visits and speeds up resolution when responses are complete and accurate.
Q10. What happens if a notice is ignored?
Ignoring an income tax notice can lead to adverse consequences, including ex-parte assessments, tax demands, interest, and penalties. Continued non-compliance may also result in further scrutiny or recovery proceedings. Timely and accurate responses are essential to avoid escalation and unnecessary financial exposure.
Q11. Does TaxBuddy support notice responses on mobile?
Yes, the TaxBuddy mobile app supports notice handling on mobile devices. It allows document uploads, transaction reconciliation, guided responses, and communication with tax experts. This enables users to manage notices efficiently without relying on desktop access or manual paperwork.
Q12. How long does it take to resolve a capital gains notice?
The time required to resolve a capital gains notice depends on the complexity of the mismatch and the quality of the response. Simple clarifications may be resolved within a few weeks, while cases involving revised returns or detailed verification may take longer. Providing accurate computations and complete documentation at the first response stage significantly shortens resolution timelines.
