The Income Tax Department has issued over 44,000 notices linked to virtual digital asset income this year, uncovering more than INR 888.82 crore in gains that were never declared. Section 133(6) is one of the tools tax officers can use to request documents and explanations directly, even before opening a formal scrutiny assessment.
However, responding within the prescribed deadline is critical. If you fail to reply in time, the department may initiate reassessment proceedings by first issuing a notice under Section 148A, followed by a notice under Section 148 where the legal conditions are satisfied. At that stage, your income may be estimated on a best judgment basis, often resulting in a higher tax demand than a timely and complete response would have produced.
To help you prepare, this guide explains who is authorised to issue a Section 133(6) notice, the records crypto traders should gather before responding, and the consequences of missing the prescribed deadline.
Key Takeaways
- A Section 133(6) notice allows authorised income tax officers to request information, documents, and transaction details related to a tax enquiry, even before a formal assessment begins.
- Crypto investors commonly receive these notices due to mismatches between AIS/Form 26AS data and ITR filings, missing TDS records, unreported crypto income, incorrect ITR forms, or undisclosed foreign exchange holdings.
- A proper response requires reviewing the notice carefully, collecting crypto transaction records, exchange statements, wallet details, and TDS proofs, then submitting the reply through E-Proceedings or the CTN facility within the given deadline.
- Ignoring a Section 133(6) notice can lead to further action, including reassessment under Section 148, penalties for non-compliance, interest on unpaid tax, and increased scrutiny of crypto transactions.
What Is Section 133(6) of the Income Tax Act?
Section 133(6) is a provision that lets certain income tax officers ask any person, including banks, for information relevant to a tax enquiry or proceeding. This can include account statements, transaction details, or documents, and the request applies whether or not a formal assessment has already started.
The power sits with officers ranked Assessing Officer and above, such as the Deputy Commissioner (Appeals), Joint Commissioner, and Commissioner (Appeals). Higher-ranked officers can also use it even before any proceeding is formally opened, provided they get the required internal approval first.
When Can You Receive a Section 133(6) Notice?
Crypto traders face Section 133(6) notices for reasons unique to virtual digital assets, even though the section itself never mentions crypto. It grants officials broad power to request information, and five recurring patterns explain when that power gets used against crypto traders.
AIS or Form 26AS TDS Mismatch
Exchanges report the 1% TDS deducted under Section 194S directly to the department, and it appears in your AIS and Form 26AS. When that TDS shows up but the matching crypto income is missing from your ITR, the mismatch gets flagged automatically. This discrepancy between declared income and exchange-reported TDS is one of the most common triggers for a notice.
TDS Never Deducted on P2P Trades
This issue mainly catches peer-to-peer traders. Section 194S mandates 1% TDS on every VDA transfer, but P2P transactions conducted directly between two individuals, without an exchange to withhold and deposit that TDS, often go unreported entirely. When bank records show crypto-linked transfers with no corresponding TDS trail, the department treats it as a compliance gap worth investigating.
Crypto Income Without Any ITR Filed
Some traders never file an ITR at all despite earning taxable crypto gains. Since exchanges already report TDS data against your PAN, the department can identify non-filers whose exchange activity doesn’t match any tax return on record. Once flagged, the notice usually asks for a return to be filed along with a full transaction disclosure.
Wrong ITR Form Selected
Reporting crypto gains under Schedule VDA requires ITR-2 or ITR-3, not ITR-1. Filing ITR-1 while holding VDA income, a common error among salaried investors who assume small gains don’t need a separate schedule, signals to the department that the return doesn’t match the TDS already on file. That mismatch alone can trigger a notice.
Undisclosed Foreign Exchange or Wallet Holdings
Crypto held on a foreign platform must be disclosed under Schedule FA, separate from Schedule VDA. Skipping this disclosure exposes you to the Black Money Act, where penalties for undeclared foreign assets can reach INR 10 lakh per year, regardless of the actual gain. This is the highest-stakes trigger on this list.
Who Can Issue a Notice Under Section 133(6)?
Only specific income tax officials are authorised to issue notices under this section. Their powers vary depending on the nature of the case and the jurisdiction in which it is involved.
List of Officers that Can Directly Issue Notice
The following income tax authorities can issue a Section 133(6) notice during an enquiry or proceeding:
- Assessing Officer
- Deputy Commissioner (Appeals)
- Joint Commissioner
- Joint Commissioner (Appeals)
- Commissioner (Appeals)
List of Officers Who Can also Exercise This Power:
In addition, to the above list, here are some more officials who can issue this notice:
- Principal Director General or Director General
- Principal Chief Commissioner or Chief Commissioner
- Principal Director or Director
- Principal Commissioner or Commissioner
- Joint Director, Deputy Director, or Assistant Director
Before a Proceeding is Pending:
Officers below the rank of Principal Director/Director or Principal Commissioner/Commissioner need prior approval from that senior officer before issuing a notice. Joint Director, Deputy Director, and Assistant Director are exempt from this approval requirement.
For Cross-Border Cases (Section 90 or 90A Agreements):
The power belongs to whichever authority is specifically notified under Section 131(2), and that authority can act even with no proceeding pending anywhere.
How Should Crypto Taxpayers Prepare for Section 133(6) Notices?
Crypto investors are increasingly under scrutiny for underreporting or failing to make required disclosures. Below are key steps to help you stay prepared and respond confidently if a notice is issued.
Keep Records of All Crypto Transactions
Maintain clear records of every transaction, including buys, sells, swaps, and transfers across wallets or exchanges. These records should include date, value in INR, and transaction type. Whether you are using centralised platforms or decentralised ones, every activity should be traceable. In case of a notice, these details become essential for verifying your gains and cost basis.
Download Tax Reports From Tools Like KoinX
Using a crypto tax tool helps consolidate data across multiple exchanges and wallets. Platforms like KoinX automatically sync your transactions and generate accurate capital gains and income reports. These reports reduce the chance of error and make it easier to share proof with the department in case of any information request.
Regularly Monitor Form 26AS and AIS
Check your Form 26AS and Annual Information Statement for entries related to crypto earnings, large deposits, or high-value purchases. Any data mismatch between your ITR and these forms may result in a Section 133(6) notice. Early detection helps you file an updated return before a notice is issued.
Declare Foreign Wallets in ITR if Applicable
If you use international exchanges or store cryptocurrency in non-Indian wallets, declare them clearly in your ITR under ‘Foreign Assets’. Failing to do so may violate FEMA and DTAA rules. If a notice is issued, you will be expected to submit wallet addresses, KYC details, and transaction history. Transparency is key to avoiding larger legal issues later.
How Long Should You Retain Your Tax Records?
Taxpayers are advised to retain their income tax records, including proofs of income, deductions, and asset transactions, for a minimum of 6 to 10 years. This is especially important in case the department issues a Section 133(6) notice many years after the original return was filed. The longer retention period allows you to defend your filings with proper evidence even in delayed enquiries.
For crypto users, the need for recordkeeping is even more critical. Wallet statements, exchange summaries, on-chain transaction logs, and staking reports must be stored securely. Since crypto tax treatment continues to evolve, older transactions may be reassessed under new rules. Having these records easily accessible can save time and prevent penalties during any future scrutiny.
How to Respond to a Notice Under Section 133(6)?
The notice states its own deadline, and missing it can escalate the matter to a Section 148 reassessment. Responding correctly involves five steps and one portal feature that most crypto traders don’t know exists: the Comply to Notices (CTN) facility.
Step 1: Read the Notice in Full
Note exactly what information is requested, which officer issued it, and the response deadline. For crypto traders, this usually means wallet addresses, exchange statements, or transaction history for a specific financial year. Missing a request buried in the notice, rather than ignoring the notice outright, is what most often leads to a follow-up notice under Section 148.
Step 2: Gather the Supporting Documents
Collect the exact proof the notice asks for. For crypto income, that typically means exchange-generated transaction reports, wallet statements, TDS certificates under Section 194S, and the matching AIS or Form 26AS extracts. Label every document by financial year, since assessing officers commonly request records going back several years at once.
Step 3: Choose Your Response Channel
Two channels exist. The e-filing portal’s E-Proceedings tab handles most Section 133(6) notices tied directly to your own PAN. Notices connected to someone else’s assessment, such as a transaction counterparty’s proceeding, more often route through the CTN facility instead, using the Document Identification Number (DIN) printed on the notice.
Step 4: Use CTN If the Notice Isn't in E-Proceedings
Some notices arrive by email but never appear in the E-Proceedings tab, typically because they’re tied to another PAN or TAN rather than yours. CTN exists for this exact gap: enter the DIN and the requested details directly under Quick Links on the portal, and the response still reaches the department correctly.
Step 5: Submit and Keep Proof of Filing
Upload the requested documents in the format specified, choosing a full or partial response depending on what you currently have ready. Download the acknowledgment receipt once submission is complete. This becomes your evidence of timely compliance if the department later disputes whether, or when, a response was filed.
Step 6: Bring in a Tax Professional for Complex Cases
Notices involving foreign wallets, DeFi activity, or transactions spread across multiple exchanges are harder to reconstruct without expert input. A professional can verify cost-basis calculations, interpret ambiguous wallet activity, and draft a response precise enough to close the enquiry rather than invite a second notice.
What Happens If You Ignore or Delay Your Response?
Ignoring a Section 133(6) notice is never a good idea. The Income Tax Department considers non-response as a sign of non-compliance or deliberate withholding of information. This could trigger stricter actions and additional notices.
Once the deadline passes without a proper response, your case may be flagged for further review. In crypto cases, especially, silence may be interpreted as an attempt to hide foreign wallets or undeclared gains. Here’s what could happen if you do not respond on time:
- Escalation to Section 148: The department may initiate reassessment proceedings and require you to file a new return with complete disclosures.
- Invalidation of Earlier ITR: Your previously filed return might be disregarded if key income sources remain unverified.
- Heavier Penalties: You could face daily fines or a 200% penalty if misreporting is proven.
- Increased Audit Risk: Non-response increases the chance of your case being selected for audit in future years.
- Prosecution Possibility: If the department finds clear evidence of tax evasion, it may initiate criminal proceedings against the individual.
What are the Penalties for Non-Compliance Under Section 133(6)?
If you fail to respond to a Section 133(6) notice or submit incorrect information, the Income Tax Department can take strict action. Below are the penalties you may face.
Daily Penalty Under Section 272A
When a reply isn’t filed within the deadline, Section 272A allows a penalty of INR 500 for every day the failure continues, with no cap until a proper response is submitted. 30 days of delay adds ₹15,000 in penalty alone, on top of whatever the original notice was investigating.
Penalty for Misreporting Income or Exemptions
If your reply reveals income that was never disclosed, the Assessing Officer can levy a penalty under Section 270A. A straightforward gap between what you declared and what gets assessed, such as an unreported crypto gain, draws a 50% penalty on the tax due.
If the gap results from something the law treats as deliberate, like a false entry in your records or misrepresented facts rather than an honest omission, the penalty rises to 200% of the tax due, on top of the tax itself.
Crypto Penalty Examples
Crypto traders who fail to disclose digital asset earnings or can’t explain wallet inflows face real consequences beyond the immediate penalty.
The department can reassess the case under Section 148, and unpaid tax accrues interest at 1% per month (12% annually) under Sections 234A and 234B. In cases involving willful concealment, whether through undisclosed foreign wallets under the Black Money Act or domestic evasion under Section 276C, prosecution can lead to imprisonment, with terms of up to seven years for larger amounts. Accurate records and full disclosure are the only way to stay outside that risk entirely.

Frequently Asked Questions
I haven't responded to my Section 133(6) notice yet and the deadline is close. What happens if I miss it?
Missing the deadline doesn’t close the matter, it escalates it. The department can proceed to a Section 148 reassessment and estimate your income on a best judgment basis, which typically results in a higher demand than a timely response would have. Respond as soon as possible, even with a partial submission, rather than waiting until you have every document ready.
Can a Section 133(6) notice turn into a full tax audit?
Yes, if your response reveals discrepancies the officer can’t resolve from documents alone. A pattern of unreported crypto transactions, foreign wallet activity, or repeated TDS mismatches raises the likelihood of your case being selected for closer scrutiny in future assessment years. A single, well-documented notice rarely triggers an audit on its own.
What is the CTN facility, and when should I use it instead of the E-Proceedings tab?
CTN stands for Comply to Notices, a feature on the income tax e-filing portal that lets you respond using the notice’s Document Identification Number (DIN). Use it when a notice arrives by email but doesn’t appear in your e-Proceedings tab, which typically happens when the notice is tied to another party’s PAN or TAN rather than your own.
I already filed my ITR without reporting my crypto gains, and now I've received this notice. Can I still fix it?
Yes, through an Updated Return (ITR-U) under Section 139(8A), which can be filed within 48 months from the end of the relevant assessment year. Filing an ITR-U requires paying additional tax on top of what was originally owed: 25% if filed within 12 months, 50% between 12 and 24 months, 60% between 24 and 36 months, and 70% between 36 and 48 months.
I traded crypto on a foreign exchange like Binance or Bybit. Does that change how I should respond?
Yes. Foreign exchange holdings need to be reported under Schedule FA in addition to Schedule VDA, and if that disclosure was missed, your response needs to address both gaps. Under the Black Money Act, failing to disclose foreign assets in Schedule FA carries a penalty of INR 10 lakh per year under Section 43, separate from your crypto tax liability. If the department finds undisclosed foreign income or assets during assessment, Section 41 adds a penalty equal to three times the tax.
