Filing a crypto ITR is not like filing a standard salary return. The Income Tax Act imposes conditions spanning income head classification, Schedule VDA reporting, TDS reconciliation, and, where applicable, financial statement disclosures. As a result, a crypto investor can fall short on any one of these requirements without even realising it. Even a seemingly minor omission can make a return defective.
When the Centralised Processing Centre (CPC) identifies such a defect during processing, it issues a notice under Section 139(9) of Income Tax Act, 1961. The reason can vary. It may be an incorrect income head, an incomplete Schedule VDA, or a missing financial statement. The notice clearly identifies the defect and gives you 15 days (or such extended time as permitted in the notice) to rectify the defect.
This guide explains exactly what that 15-day window means and how to respond. A Section 139(9) notice is neither a penalty nor a scrutiny assessment, and it does not imply fraud. Instead, it gives you an opportunity to correct the identified defect. If you rectify the issue within the prescribed time, your return continues to be processed as though the defect had not occurred.
Key Takeaways
- A Section 139(9) notice is a correction request from the CPC, not a penalty, scrutiny notice, or investigation into your affairs.
- Crypto ITRs attract defective notices because exchange Statement of Financial Transaction (SFT) data and Section 194S TDS credits create multiple mismatch points in your Annual Information Statement (AIS).
- A TDS credit from an exchange with no Schedule VDA entry in the return is the single most common crypto defect trigger.
- You have 15 days to respond; fix the defect in time and the return is accepted as originally filed with zero further consequences.
- The ITD’s own published guidance covers five steps, all completed on the e-filing portal.

What Is a Section 139(9) Defective Return Notice?
Section 139(9) of the Income Tax Act, 1961 empowers the Centralised Processing Centre (CPC) to treat an income tax return as defective during processing under Section 143(1). The CPC compares the details reported in your ITR with Form 26AS and the Annual Information Statement (AIS). If it identifies a mismatch or omission, it may issue a defective return notice.
A Section 139(9) notice is neither a penalty nor a scrutiny or reassessment notice. It is a system generated communication from the CPC that highlights a defect requiring correction before your return is processed. It does not imply fraud or an investigation into your crypto transactions. Instead, it gives you an opportunity to rectify the identified issue within the prescribed time.
How Does the Notice Reach You?
A Section 139(9) notice is sent to the email address registered on your Income Tax e filing portal account, with an SMS alert sent to your registered mobile number. It is also available on the portal under Pending Actions, then e-Proceedings, in the For Your Action tab. The email subject reads, “Communication u/s 139(9) for PAN [X] for AY [X]”, and includes a password protected PDF attachment.
The notice contains your PAN, assessment year, acknowledgement number, the specific defect identified, and the response deadline. To open the PDF, use your PAN in lowercase followed by your date of birth in DDMMYYYY format. For example, ABCDE1234F and 15 June 1990 becomes abcde1234f15061990. Read the defect description carefully and note the response deadline before taking any action.
Defective Notice under Section 139(9) Sample
How a Crypto Return Turns Defective Under Section 139(9)?
The CPC does not issue a defective notice randomly. It finds a specific mismatch between what you filed and what it holds from exchanges, AIS, and Form 26AS. These are the eight errors that most commonly trigger it for crypto investors.
TDS Credit Claimed but Schedule VDA Is Not Filled
When an Indian exchange deducts TDS under Section 194S, that entry appears in your Form 26AS and AIS. If you claim that TDS credit in the return but leave Schedule VDA blank, the CPC finds a credit with no income to match it against. This mismatch is the single most common trigger for a crypto defective notice.
An incomplete Schedule VDA produces the same result. Listing some disposals but omitting others means the credit claimed exceeds what the declared income justifies. Every disposal during the financial year must be entered individually in Schedule VDA.
AIS Gross Receipts Exceed Total Income Declared
Indian exchanges file a Statement of Financial Transactions with the ITD each financial year. This reports the total transaction value processed through their platform during the year. That figure appears in your AIS as gross VDA receipts. When it significantly exceeds your declared income across all heads, the CPC flags the difference.
This defect does not always mean under-reporting. The AIS often captures gross transaction volume, combining buy and sell values, rather than net proceeds or gains. However, the CPC works from the figures it holds. If your declared income is substantially lower than the AIS figure, a defect notice follows.
Wrong ITR Form Filed for Crypto Activity
Filing the wrong ITR form is one of the most common reasons for a defective return under Section 139(9). Each ITR form contains specific schedules based on the type of income reported. If you select the wrong form, the schedules required to report your crypto income are unavailable, preventing the CPC from verifying your return correctly.
For example, investors reporting either Income from other Sources (IFOS) or crypto capital gains should file ITR-2, while those reporting crypto income under Profits and Gains from Business or Profession (PGBP) must file ITR-3. ITR-1 cannot be used for any return involving crypto income because it does not include Schedule VDA. As a result, even a single crypto disposal or a TDS credit reported by an exchange cannot be reconciled with your return, causing the CPC to treat it as defective.
PGBP Income Declared Without Financial Statements
Declaring income under PGBP requires the return to be accompanied by a profit and loss account and a balance sheet. The statutory conditions under Section 139(9) are explicit on this. Submitting the return with PGBP income declared but no financial statements attached fails the condition directly. A defect notice follows automatically.
Where regular books are not maintained, the return must include a statement disclosing turnover, gross profit, and net profit. Crypto traders under Section 44AD are generally exempt from detailed books. However, they must still disclose turnover correctly in the return. An absent or incorrect turnover figure in a presumptive return is also treated as a defect.
Gross Total Income Shown as Nil but Tax Has Been Paid
Where all income heads show nil or zero but a TDS credit or self-assessment tax payment appears in the same return, the CPC identifies an irreconcilable entry. A tax credit cannot be applied against zero declared income. This is flagged as a defect regardless of the amount. The return is not processed until the inconsistency is resolved.
This error is common among investors who received TDS from an exchange but decided not to declare income. The TDS entry remains visible in AIS regardless of the filing decision. Declaring zero income while claiming a TDS credit is always a defect. The correct approach is to declare the actual income and claim the credit against it.
Total Income Shown as Nil but Tax Has Been Paid
When all income heads are reported as nil, but the return contains TDS credits or tax payments, the CPC identifies a mismatch that cannot be reconciled. Since tax credits must correspond with declared income, a zero income declaration creates an inconsistency. This commonly occurs when crypto investors report exchange TDS but fail to declare the related VDA gains.
Therefore, the return becomes defective because the CPC cannot match the tax paid with the income disclosed. Before filing, ensure that all crypto income is correctly reported under the relevant head and that the TDS credits claimed, align with the declared VDA transactions to avoid a Section 139(9) notice.
Audit Report Missing Despite Crossing the Section 44AB Threshold
If a crypto trader’s turnover exceeds the applicable threshold under Section 44AB, a tax audit may become mandatory. The general business threshold is INR 1 crore, which can increase to INR 10 crore where cash receipts and cash payments each do not exceed 5% of the respective totals. Consequently, the audit report must be completed and furnished along with the income tax return. Filing the return without attaching the required audit report makes the return defective.
Moreover, crypto turnover is calculated differently from net profit. It refers to the absolute sum of profits and losses from trading activities, rather than the final net figure. Therefore, traders must accurately calculate turnover to determine whether the Section 44AB audit requirement applies.
BSR Code and Challan Details Missing or Incorrect
When crypto traders pay advance tax or self assessment tax, they must report complete challan details in the return. This includes the BSR code, challan date, and serial number. However, missing or incorrect details can make the return defective even if the tax payment has already been completed.
The CPC relies on these details to identify and validate the payment against its records. Therefore, you must verify every challan entry before filing. Checking the details against the OLTAS portal helps ensure that the CPC can successfully match the tax payment with your return.
Name in the Return Does Not Match PAN Records
The name entered in your income tax return must exactly match the name registered with your PAN in the Income Tax Department’s records. Any mismatch, including differences caused by nicknames, abbreviations, or spelling variations, can result in a defective return notice.
This issue can affect crypto investors who trade or maintain accounts under names different from their PAN records. Therefore, before submitting your return, verify the exact name linked with your PAN and ensure that the same details appear in your ITR to prevent processing delays.

Timeline to Submit a Response to Defective Return
After receiving a defective return notice under Section 139(9), you must rectify the identified defect and submit your response within 15 days from the date of receiving the notice. You can also request an extension by submitting an application to the Assessing Officer explaining the reason for the delay.
Although the 15 day deadline is mandatory, the Assessing Officer may condone a delayed response if you rectify the defect before the assessment is completed. However, failure to respond or obtain an extension can make your original return invalid, leading to consequences such as interest, loss of carry forward benefits, penalties, and forfeiture of certain exemptions.
How to Respond to a Section 139(9) Notice on the ITD Portal?
The Income Tax Department publishes five steps for responding to a defective notice. These steps, sourced from the official Response to Defective Notice page, are all completed through the e-filing portal.
Step 1: Log In to the ITD Portal
Go to incometax.gov.in and log in using your PAN and password. Ensure the registered email address and mobile number on the portal are current. If they are outdated, update them before attempting to respond. The response process requires validated credentials throughout.
Step 2: Click the e-Proceedings Tab and Select the Notice
On the portal dashboard, click on Pending Actions, and then the e-Proceedings tab.
This is where all notices requiring a response are listed. Select the defective return notice from the list and click View. The notice appears under the “For Your Action” section.
Step 3: View the Defective Notice After Validation
On successful validation, the defective notice is displayed on screen. This is the same document sent to your registered email address. It shows the specific defect the CPC identified, the assessment year, and your response deadline. Read the defect description fully before proceeding to the next step.
Step 4: Click Submit in the Response Column
In the response column next to the notice, click Submit. Two options appear: Agree and Disagree. Select Agree if the defect is genuine and you intend to correct it. Select Disagree only if the defect is based on data that does not apply to your return. Once submitted, the response cannot be updated or withdrawn.
Step 5: Select the ITR Form and Upload the Corrected File
Select the relevant ITR form from the dropdown. Then upload the corrected XML or JSON file generated through the ITD offline utility or authorised tax filing software. The corrected file must address the specific defect listed in the notice. After uploading, click Submit to finalise the response.
If additional tax has become payable as a result of the correction, pay the outstanding amount as self-assessment tax before uploading. A return with unresolved tax dues may not be accepted as a valid response by the portal.
Should You Agree or Disagree With the Defective Notice?
When responding to a defective return notice under Section 139(9), you must choose between Agree and Disagree based on whether the defect identified by the CPC is valid. The correct selection depends on whether the issue requires correction in your return or whether the information used by the CPC is incorrect.
When to Select Agree?
Select “Agree” when the defect identified is a genuine error in your filed return. For crypto investors, this is the appropriate response in most cases.
You should select Agree when:
- Schedule VDA is missing or incomplete: If you failed to report crypto income or gains under Schedule VDA, the defect must be accepted and corrected.
- Wrong ITR form is filed: If you filed ITR-1 despite having crypto income or used an incorrect form for your income type, you must file the appropriate revised return.
- TDS credit is claimed without declaring corresponding income: If exchange TDS appears in your records but the related VDA income was not reported, you need to correct the return.
After selecting Agree, correct the specific defect mentioned in the notice and upload the revised return. If you rectify the genuine defect within 15 days, the return continues to be treated as valid from the date of original filing. The defect itself does not attract any penalty. Additional tax becomes payable only if the correction results in previously undeclared income.
When to Select Disagree?
Select “Disagree” only when the defect is based on incorrect information that does not belong to your return. In such cases, you must provide a valid explanation along with supporting documents through the income tax portal.
You should select Disagree when:
- Incorrect TDS credit appears against your PAN: For example, an exchange reports TDS under your PAN due to an error, but the transaction does not belong to you.
- AIS contains incorrect transaction details: If the Annual Information Statement reflects a transaction that you never carried out, you can dispute the information.
However, do not select Disagree simply to avoid reporting crypto income that you actually earned. If the defect is genuine and you disagree without valid grounds, the CPC may process the return based on available information, which can result in an incorrect tax demand or loss of eligible claims.
Can You File a Revised Return Instead of Responding to the Notice?
It depends on whether the filing window for that assessment year is still open. If it is, you can file a fresh or revised return under Section 139(5) instead of responding to the notice. Once that window has lapsed, filing a fresh or revised return is no longer possible, and you must respond directly to the Section 139(9) notice through e-Proceedings on the portal. Failing to respond within the stipulated period means the return is treated as invalid, which can trigger penalties, interest, and loss of carry-forward benefits.
Therefore, the recommended approach is to respond to the Section 139(9) notice first and then file a revised return if you need to make additional corrections beyond the identified defect. For AY 2026 27, the revised return deadline is 31st March 2027. Filing between 1st January 2027 and 31st March 2027 attracts a late fee of INR 5,000 under Section 234I, reduced to INR 1,000 if your total income does not exceed INR 5 lakh. Both actions remain separate obligations.

Frequently Asked Questions
Let’s answer some of the frequently asked questions about crypto tax India:
I Received a Section 139(9) Notice After Filing My Crypto ITR. Is This the Same as a Scrutiny Notice?
No. A Section 139(9) defective return notice and a Section 143(2) scrutiny notice are entirely different. A defective notice is a system-generated correction request from the CPC. It carries no penalty and signals no investigation. A scrutiny notice signals that the Assessing Officer intends to examine your return in detail. The two should never be confused.
My Form 26AS Shows TDS From My Exchange but I Forgot to Fill Schedule VDA. What Do I Do Now?
Log in to the e-filing portal, go to e-Proceedings, and select the defective notice. Choose Agree, then prepare a corrected ITR using the offline utility with Schedule VDA fully completed. Upload the corrected JSON file. The cost of acquisition for each disposal is the purchase price; the gain above that is taxed at 30% under Section 115BBH.
I Filed ITR-2 but I Have Crypto Business Income. Will This Trigger a Defective Notice?
Yes, it is likely. Crypto business income classified under PGBP requires ITR-3, not ITR-2. If you have filed the wrong form, Agree with the defective notice and re-file using ITR-3. Transfer all income data to the correct form and include any required schedules, including a balance sheet and P&L account where books are maintained.
I Received a Crypto Defective Notice and Declared Nothing. What Is My Exposure?
Your exposure depends on what the CPC identified. If exchange TDS credits appear in AIS but no income was declared, the mismatch will be flagged. Agree with the notice, declare the income correctly, and pay any outstanding tax before uploading the corrected return. Under-reporting carries a penalty of 50% of the tax shortfall under Section 270A.
I Submitted My Response and Realised It Was Incorrect. Can I Change It?
No. Once submitted, the response to a Section 139(9) notice cannot be updated or withdrawn. The ITD portal confirms this explicitly. If the submitted response was incorrect, file a revised return under Section 139(5) before 31st March 2027 to correct the figures on record. Consult a qualified CA before taking that step.
I Filed a Revised Return After Receiving the Notice. Do I Still Need to Respond on the Portal?
Yes. Filing a revised return does not satisfy the obligation to respond to a Section 139(9) notice. The notice remains listed under Pending Actions until you respond directly through e-Proceedings. The safest approach is to respond to the notice first and then file the revised return as a secondary step if broader corrections are needed.
