Tax authorities monitor capital gains reporting closely to ensure accurate tax compliance. When discrepancies arise between the information reported by taxpayers and data received from brokers or financial institutions, a tax notice may be issued requesting clarification or correction. Such notices are common when capital gains are underreported, misclassified, or incorrectly calculated. Promptly addressing these notices is vital to avoid penalties, interest charges, and further scrutiny. Let's explore how to understand tax notices related to capital gains errors, respond effectively, file corrected returns, and how tools like TaxBuddy can assist in this process.

How to respond to tax notices for Incorrect Capital Gains Reporting and Filing Corrected Returns?
Start by identifying the section under which the notice is issued. Each section of the Income Tax Act corresponds to different circumstances and requires a tailored response:
Section 139(9): This implies a defective return. The Income Tax Department has found certain missing or incorrectly filled details in your return—perhaps a mismatch in capital gains figures or missing Schedule CG. This is generally easy to rectify within the given time.
Section 142(1): This is a more detailed request where the assessing officer needs additional documentation or clarification. This may include explanations of large capital gains, mismatch with AIS/TIS, or missing cost of acquisition proofs.
Section 148: This is more serious. It is issued when the department believes that you have not reported taxable income—such as capital gains from sale of shares, property, or mutual funds—which should have been disclosed. This can lead to reassessment.
Your immediate next steps should be:
Log into the Income Tax e-filing portal (incometax.gov.in).
Access the 'e-Proceedings' tab to locate the specific notice.
Download and read the notice thoroughly. Understand the nature of the mismatch or missing data.
Compare your ITR with AIS and TIS reports to spot the discrepancies.
Cross-check with broker statements, demat records, and capital gains summary.
If you identify genuine errors, file a revised return under Section 139(5) before the due date.
Prepare a detailed response and attach supporting documents if no error exists.
What Are Tax Notices for Incorrect Capital Gains Reporting?
A tax notice for incorrect capital gains reporting is a formal intimation by the Income Tax Department highlighting a mismatch between the capital gains reported in your Income Tax Return and the data received from third-party sources. These third parties include depositories (like NSDL/CDSL), registrars and transfer agents (RTAs), mutual fund houses, stock exchanges, and banks.
The department now receives real-time transactional data from these sources, which gets auto-populated in your AIS (Annual Information Statement) and TIS (Taxpayer Information Summary). If your filed ITR fails to reflect this information accurately, a tax notice is issued to seek clarification.
The most commonly used sections are:
Section 139(9): Indicates that your return is defective. This could be due to wrong or missing entries in Schedule CG or inconsistencies in capital gains calculations.
Section 142(1): Issued when the AO needs further documentation or explanation regarding a mismatch or questionable reporting of capital gains.
Section 148: Indicates that the department has found income that was not reported at all (e.g., unreported capital gains) and wants to reassess your case. You are required to furnish a fresh return or face legal assessment proceedings.
Common Causes of Capital Gains Reporting Errors
Capital gains computation and reporting involve multiple steps, and it’s easy to make mistakes. Here are the most common causes:
Omitted Transactions: Many taxpayers forget to report the sale or redemption of shares, mutual funds, or property.
Even exempt transactions should be reported in the return.
Incorrect Cost of Acquisition: Not adjusting the cost for bonuses, rights issues, or stock splits.
In real estate, excluding stamp duty or registration fees from cost basis.
Wrong Classification: Confusing short-term capital gains (STCG) and long-term capital gains (LTCG).
For equity investments, assets held for more than 12 months are LTCG. For other assets, the period is 36 months.
Ignoring Grandfathering Rule: For shares and equity mutual funds bought before 1st Feb 2018, the FMV as on 31 Jan 2018 should be used while computing LTCG under Section 112A.
Failing to apply this rule can lead to inflated taxable gains.
Unsubstantiated Exemptions: Claiming exemption under Section 54 (property reinvestment), 54F (alternate property), or 54EC (bonds) without actual compliance or documentation.
Mismatch with AIS/TIS: Not verifying and reconciling your ITR with AIS or TIS data.
Inconsistent ISIN-wise details or failure to report capital gains reported by brokers.
Such errors can lead to under-reporting of taxable income, resulting in interest and penalties—or even reopening of assessment in severe cases.
Tip: Always download and reconcile your AIS and TIS before filing ITR, especially if you have active investments.
How to Respond to a Tax Notice on Capital Gains
Once you've reviewed the notice and identified the cause, you need to take action promptly. Here's a detailed breakdown of the steps:
Step 1: Review the Notice in Detail
Access the Income Tax e-filing portal and navigate to the 'e-Proceedings' or 'View Notices and Orders' section.
Carefully read the notice to understand the nature of the issue. Take note of the section under which it is issued, response deadline, and the financial year concerned.
Step 2: Reconcile ITR with AIS and TIS
Download your Annual Information Statement (AIS) and Taxpayer Information Summary (TIS) from the portal.
Match each transaction listed (especially capital gains from securities and mutual funds) with what you declared in your ITR.
Step 3: Gather Supporting Documentation
Prepare the following documents:
Demat account statements showing purchase and sale of securities
Contract notes for each transaction
Broker gain/loss summary reports
Property purchase and sale deeds
Cost of acquisition and improvement proofs
Investment proofs under Section 54, 54F, or 54EC if exemptions are claimed
Step 4: Draft a Structured Response
If you agree with the discrepancy, prepare to file a revised return.
If you disagree, prepare a detailed explanation, highlighting why your original return is accurate, backed by your documentation.
Use tables or spreadsheets to summarize ISIN-wise or property-wise calculations.
Step 5: Submit Response Online
Navigate to the e-Proceedings module and select the relevant notice.
Upload your documents in PDF format (1 MB per file is the general limit).
Enter your explanation in clear, concise language.
Submit and then e-verify your response.
Step 6: Follow Up
Regularly check the portal for updates.
If additional clarifications are requested, respond within the stipulated timeframe.
How to File Corrected Returns for Capital Gains Mistakes
When the discrepancy leads to underreported capital gains, it is advisable to file a revised return under Section 139(5). Here is how to do it accurately:
When Should You File?
If your original return was filed on time (i.e., before the due date under Section 139(1))
If you discover a mistake after receiving a notice
If the difference in capital gains affects your taxable income or refund
Deadline:
For FY 2024–25 (AY 2025–26), the deadline to revise the return is 31st December 2025.
Key Steps:
Login to the e-filing portal and select ‘File Income Tax Return.’
Choose the relevant Assessment Year and select ‘Revised Return under Section 139(5)’.
Choose the correct form (usually ITR-2 or ITR-3) depending on your income source.
Under Schedule CG, re-enter your capital gains data accurately:
Mention ISIN-wise details for equity
Use indexed cost for long-term property/debt fund gains
Calculate gains using FMV for equity LTCG acquired before 1 Feb 2018
Recalculate the tax liability and ensure all taxes are paid with applicable interest.
E-verify the revised return using Aadhaar OTP, net banking, or DSC.
Important:
Keep acknowledgment (ITR-V) as proof
If there’s a tax liability, pay immediately to avoid 234B/234C interest accrual
Documents and Evidence Required for Response
Accurate and complete documentation is critical for a successful resolution. Below is a categorized checklist:
For Equity and Mutual Fund Transactions:
Demat Account Statements: For the full financial year
ISIN-Wise Trade Summary: Available from your broker or portal like CAMS/Karvy
Contract Notes: PDF versions of buy/sell confirmations from your stock broker
Capital Gains Statements: Provided by brokers and mutual fund houses
For Property Transactions:
Purchase Agreement & Sale Deed
Payment Proofs: Bank statements or cheque copies
Stamp Duty & Registration Fee Receipts
Indexed Cost Calculation Sheet
For Exemption Claims:
Proof of Reinvestment under Section 54/54F: New property registration documents
Bond Purchase Receipt (54EC): NHAI or REC bond certificates
General:
AIS and TIS PDF copies
Form 26AS for tax credit verification
Tax computation sheets with gain/loss breakup
Organize these in folders by asset type and year. If uploading to the Income Tax portal, convert them to clearly labeled PDFs and ensure legibility.
Timelines and Deadlines for Responding to Notices
Responding to income tax notices—especially those related to capital gains—within the prescribed timeline is crucial. Delays can lead to automatic assessments, loss of appeal rights, and interest or penalties.
Typical Timelines Based on Section:
Section | Nature of Notice | Response Deadline |
Section 139(9) | Defective return requiring correction | 15 days from issue date |
Section 142(1) | Inquiry before assessment; calls for documents | 15–30 days (as specified in notice) |
Section 148 | Reassessment due to income escaping assessment | 30 days (or as per notice instructions) |
Revised Return Timeline:
Under Section 139(5), the deadline for FY 2024–25 (AY 2025–26) is 31st December 2025.
This applies only if the original return was filed on or before the due date (31 July 2025).
Extension Requests:
Taxpayers may request an extension in writing via the e-filing portal under exceptional circumstances.
However, these are rarely granted without strong justification and prior communication.
Note: Even if you are unsure about the mistake, it’s better to respond within the deadline and seek an extension for a detailed reply later.
Consequences of Ignoring Capital Gains Tax Notices
Failure to respond to capital gains-related tax notices can result in multiple financial and legal implications. These consequences vary in severity based on the type of notice and duration of non-compliance.
1. Ex-Parte Assessment under Section 144:
If no response is submitted, the Assessing Officer can proceed with a “best judgment” assessment.
This means your tax liability will be estimated based on AIS and third-party data, often resulting in a higher tax demand.
2. Interest Accrual:
Under Sections 234A (delay in filing), 234B (shortfall in advance tax), and 234C (deferred tax installments), interest continues to accrue monthly.
3. Penalty under Section 270A:
If underreporting is confirmed, you may be charged a penalty of 50% of the tax payable on the misreported income.
In case of misreporting with intent to evade taxes, the penalty can go up to 200%.
4. Loss of Refund and Carry-Forward Benefits:
Ignoring notices may lead to denial of your refund or disqualification from carrying forward capital losses to future years under Section 74.
5. Prosecution under Section 276C (in rare, serious cases):
Continuous evasion or non-response may be treated as tax fraud, leading to prosecution.
Punishment can include rigorous imprisonment from 3 months to 7 years and fines.
6. Increased Scrutiny in Future Years:
Non-compliance gets flagged in your taxpayer profile, leading to increased risk of audits and tighter review of your returns in subsequent years.

Q4. What forms are used to report and correct capital gains errors?
In India, capital gains are reported using Schedule CG in the ITR forms—mainly ITR-2 or ITR-3. If there's an error, you must file a revised return under Section 139(5) using the same form. Attach updated capital gains computations and supporting documents.
Q5. Will I be penalized for reporting capital gains incorrectly?
If incorrect reporting results in underpayment of tax, interest and penalties may be levied. However, promptly correcting errors by filing revised returns and paying due taxes minimizes these charges. Ignoring errors or notices can lead to higher penalties and scrutiny.

Yes, if you have capital losses exceeding capital gains, the excess loss can typically be carried forward to offset future gains. However, the original return must have been filed within the due date to carry forward losses.
Q7. How long do I have to respond to a tax notice about capital gains?
Tax notices generally specify a response deadline, often between 15 to 30 days depending on the section (e.g., 139(9), 142(1), or 148). Responding within this timeframe is crucial to avoid escalated action, penalties, or enforced assessments.
Q8. What documentation should I keep for capital gains reporting?
Maintain comprehensive records including brokerage statements, trade confirmations, demat summaries, AIS/TIS copies, cost basis documentation, sale deeds, reinvestment proofs, and any corrected tax forms. These documents support your reported gains and losses and are essential during scrutiny.
Q9. Can I disagree with the tax notice and how should I respond?
Yes. If you believe the tax authority’s notice is incorrect, you can respond by submitting detailed explanations and supporting evidence justifying your original reporting. Maintain professionalism and clarity in your communication. Consulting a tax expert is advisable in complex cases.

Q12. Are there software tools to help correct capital gains reporting errors?
Yes, several tax software platforms, including TaxBuddy, offer tools to track transactions, identify inconsistencies, and assist in filing corrected returns. These platforms help reduce manual errors and streamline the amendment process.
