Most crypto traders who receive a Section 148A notice assume it arrived because the Income Tax Department suspects errors. In reality, the department sends this notice because the Income Tax Department has information suggesting income may have escaped assessment. This may come from transaction records shared by your exchange, AIS figures that do not match your declared Schedule VDA income, or treaty-sourced information from foreign platforms that indicates undisclosed crypto activity. That distinction matters more than most people realise.
Because the ITD is working from actual data rather than suspicion, the notice is not a demand for payment but a formal and time-bound opportunity, your one chance to explain your position before the Assessing Officer decides whether to open a full reassessment under Section 148. Under Section 148A of the Income Tax Act, 1961, the AO is required to share what they found, hear your response, and obtain supervisory approval before taking that next step. A thorough reply at this stage can stop the process entirely.
Therefore, this article explains what a Section 148A show cause notice means for crypto traders and investors, how the Income Tax Department gathers the data used to issue it, how it differs from a Section 148 reassessment notice, and how to prepare a response that addresses the department’s concerns effectively.
Key Takeaways
- Section 148A is a mandatory pre-step before reassessment, the ITD must share the specific information it holds and give the assessee an opportunity to respond before issuing any Section 148 notice.
- The AO must pass a formal order under Section 148A(3) with prior approval of the specified authority under Section 151 before proceeding, a Section 148 notice issued without this order is procedurally defective.
- Crypto traders are flagged through CBDT risk management strategy, AIS and SFT data from Indian exchanges, treaty-based foreign platform data under Section 148(3)(iii), and Section 133A surveys; all six sources under the statute are exhaustive.
- Time limit: 3 years from the end of the relevant assessment year for escaped income below INR 50 lakh; 5 years for income above INR 50 lakh, effective 1 October 2024.
- The assessee receives a minimum of 7 days and a maximum of 30 days to respond, an inadequate or generic reply materially increases the risk of reassessment.
- Filing an updated return or ITR-U under Section 139(8A) may help in certain cases, but must not be done without first reviewing the implications on reassessment proceedings.
What Is a Section 148A Notice?
Both sections sit under Chapter XX-B of the Income Tax Act, 1961, a chapter dedicated entirely to counteracting tax evasion through cash transactions. They were not written with crypto in mind.
However, they apply to “any person” and “any loan or deposit,” language broad enough to capture every cash-based lending and P2P arrangement a crypto trader enters into. No CBDT notification, circular, or official guidance exempts Virtual Digital Asset transactions from either section. Hence, the provisions apply as written.
Why Was Section 148A Introduced?
Before the Finance Act 2022 amended the Income Tax Act, 1961, the Income Tax Department could issue a reassessment notice under Section 148 without first giving taxpayers an opportunity to explain the issue. As a result, many people received reassessment notices without knowing what information the department had.
The Finance Act 2022 changed that by inserting Section 148A to the Act. It made a pre-notice hearing mandatory. It requires the department to share the information it relies on, hear your response, and pass a formal order before starting reassessment. For crypto investors, this stage is often the best opportunity to explain mismatches or correct the record before a Section 148 notice is issued.
Why Do Crypto Traders and Investors Receive a Section 148A Notice?
Crypto traders and investors receive a Section 148A notice only when the Assessing Officer possesses information falling within one of the six categories specified under Section 148(3). Section 148A does not create separate triggers. Instead, it governs the procedure by requiring a show cause notice, your response, and a reasoned order before a Section 148 notice can be issued.
Risk Management Strategy Flags
CBDT’s risk management strategy cross-references Section 194S TDS filings, AIS data, and taxpayer profiles to catch mismatches between exchange-reported volume and declared income. Where AIS shows crypto turnover but your ITR carries no Schedule VDA entry, or reports a net gain far smaller than gross volume, that discrepancy alone qualifies as information under Section 148(3)(i), with no separate trigger required.
Audit Objections
An audit objection arises when a review of a completed assessment finds it wasn’t made in accordance with the Act. For crypto traders, this can surface where an earlier assessment applied the wrong tax treatment to VDA gains, allowed a loss set-off against other income that Section 115BBH prohibits, or missed a TDS credit reconciliation error. That objection independently qualifies as information under Section 148(3)(ii).
Treaty Information
Where a trader holds accounts on foreign exchanges based in jurisdictions with which India has a tax treaty, information exchanged under agreements referenced in Section 90 and Section 90A can surface offshore crypto holdings never reported in an Indian ITR. This cross-border data sharing qualifies as information under Section 148(3)(iii), independent of anything an Indian exchange has reported domestically.
Section 135A Scheme Information
Section 135A lets CBDT notify a centralized scheme for AOs to receive certain information directly. Where crypto-specific data, such as exchange records or wallet-linked details, is routed through a notified 135A scheme, it qualifies as information under Section 148(3)(iv). Notably, Section 148A(4) exempts this category from the usual show-cause procedure, meaning no prior opportunity to reply before a 148 notice is issued.
Tribunal or Court Orders
Where an appellate tribunal or court rules on a crypto tax dispute, such as Section 115BBH’s applicability to a specific transaction type, a TDS credit dispute, or how a particular token should be classified, that ruling can require the AO to revisit related assessment years. Any consequential action flowing from such an order independently qualifies as information under Section 148(3)(v).
Survey Information Under Section 133A
Since 1 September 2024, information gathered during an income-tax survey conducted under Section 133A qualifies as valid information under Section 148(3)(vi). For crypto traders, this could include records found during a survey of an exchange’s Indian office or a trader’s own business premises. This is the most recently added category, reflecting expanded enforcement visibility into exchange-side and business records.
When Can the ITD Issue a Section 148A Notice for Crypto Transactions?
The ITD’s power to reopen is not unlimited. Strict time limits govern when a Section 148A notice can be issued, and a notice served beyond those limits is invalid. This is one of the most important things to verify the moment a notice arrives.
Escaped Income | Time Limit |
Below INR 50 lakh | 3 years from end of relevant assessment year |
INR 50 lakh and above | 5 years from end of relevant assessment year |
Section 135A scheme cases | Special provisions apply; prior approval of specified authority mandatory |
The time limit for issuing a Section 148A notice depends on the circumstances of your case. Following the Finance Act, 2024, the maximum time limit for high value escaped income cases was reduced from 10 years to 5 years, with effect from 1 September 2024. If the Income Tax Department issues a Section 148A notice after the applicable time limit has expired, the notice may be legally invalid, and you can raise this objection in your reply.
What Information Does the ITD Attach to a Section 148A Notice for Crypto?
Under Section 148A(1), the ITD must attach the specific information it is relying on to the show cause notice. For crypto traders, this typically takes one of four forms, and identifying which form applies to your notice determines the exact documents your response must address.
AIS Volume Mismatch
The most common attachment is a summary of the trader’s AIS showing gross crypto transaction volume alongside the declared Schedule VDA income. Where the two figures diverge significantly, the AIS data is the stated basis. The ITD’s gross figure includes every buy and sell side of a transaction, it is not a net gain figure, and many notices arise simply because the trader did not explain how that gross volume reduces to the declared net.
SFT Data From Indian Exchanges
The ITD may attach SFT filings made by Indian exchanges showing specific transaction records, dates, values, and counterparty data, that were not disclosed in the ITR. These records are granular and date-specific, which is why a response to an SFT-based notice must be equally precise.
Foreign Transaction or Treaty Information
Where the basis is treaty-sourced data, the notice typically references information received under Section 90 or Section 90A without disclosing the foreign jurisdiction’s internal records in full. The trader is informed that foreign platform data indicates undisclosed activity. The response must establish that those transactions were either already declared or were not taxable events.
Section 68 Unexplained Credit Flag
Where P2P or OTC transactions were flagged as unexplained cash credits, the notice references specific bank account credits or wallet inflows that the ITD cannot reconcile with declared income. The response must establish the source, nature, and taxability of those credits with documentary evidence.
What Is the Difference Between a Section 148A Notice and a Section 148 Notice?
Section 148A notice and a section 148 notice are frequently confused with each other. That confusion leads to the wrong response at the wrong stage. One is the warning before the door opens. The other is the door opening. The distinction shapes everything that follows. Here’s the distinction listed in simple words:
Section 148A Notice | Section 148 Notice | |
What It Is? | Show cause notice before reassessment | Formal notice to file a return for reassessment |
When Issued? | Before any reassessment, mandatory first step | After Section 148A(3) order is passed |
What It Attaches? | Specific information the ITD is relying on | Copy of the Section 148A(3) order |
Taxpayer Obligation | Submit a factual, documented reply | File a return of income within 3 months |
Supervisory Approval | Required for Section 148A(3) order under Section 151 | Required under Section 135A scheme cases |
Can It Be Challenged | Yes, on procedural and factual grounds | Yes, if Section 148A process was not correctly followed |
Time Limit | 3 years (normal); 5 years (above INR 50 lakh) | Runs from the Section 148A(3) order date |
Consequence of Ignoring | AO passes order and issues Section 148 notice | Ex-parte assessment, additional tax, penalties, prosecution risk |
How to Respond to a Section 148A Notice for Crypto Transactions?
A thorough response at this stage is the single most effective intervention available. Reassessment is not inevitable, the Section 148A process was designed to give the assessee a genuine opportunity to prevent it. What it requires is a specific, documented reply mentioned below that directly addresses the information the ITD has attached.
Step 1: Read the Notice and Identify the Exact Basis
Read the full notice and the attached information carefully. Identify the assessment year in question, the specific allegation, AIS mismatch, SFT discrepancy, unexplained credit, or foreign platform data, and the deadline for response. The reply must address the exact basis stated. A general defence of your overall tax compliance does not satisfy the requirement.
Step 2: Pull Every Relevant Record for That Assessment Year
Before drafting any response, gather the following:
- ITR copy and Schedule VDA for the relevant assessment year
- AIS and Tax Information Summary from the income tax portal
- Exchange transaction statements across every platform used during the year
- Wallet transaction histories with dates and INR FMV at each transaction date
- Form 26AS showing TDS credits
- Bank statements confirming INR inflows from crypto disposals
- Form 26QE filings for any P2P transactions
- Counterparty KYC records for P2P or OTC trades
Step 3: Reconcile AIS Gross Volume Against Schedule VDA Net Gain
The most common mismatch the ITD raises is between the gross figure in AIS and the net gain declared in Schedule VDA. Prepare a transaction-level reconciliation showing exactly how the gross volume reduces to the declared net, accounting for cost of acquisition on each disposal. This reconciliation is the central document in most crypto-related responses.
Own-wallet transfers between the assessee’s own addresses are not disposals and should not appear in Schedule VDA. Where the ITD’s SFT data has included such transfers in the gross figure, identify them explicitly and support that identification with wallet address ownership records.
Step 4: Establish That the Income Was Already Assessed
Where the income the ITD is questioning was already reported in the ITR under the correct head, demonstrate that through the return copy, computation, and Schedule VDA entries. Cross-reference the relevant AIS line items to the specific Schedule VDA entries. Make the connection explicit, do not leave the AO to draw that conclusion independently.
Step 5: Address P2P and Foreign Platform Transactions Specifically
For P2P transactions flagged as unexplained cash credits, provide counterparty KYC documentation, platform confirmation of the trade, cost of acquisition, and the INR FMV on the date of receipt. For foreign platform transactions, attach exchange statements showing the complete transaction history, cost basis, and any applicable TDS deposited via Form 26QE. The burden rests on the assessee to establish that every transaction was disclosed and correctly treated.
Step 6: Verify Whether the Notice Is Time-Barred or Procedurally Defective
Before filing the substantive reply, check two things. First, whether the notice was issued within the applicable time limit for the escaped income amount alleged. Second, whether the specific information is actually attached as required by Section 148A(1). A notice issued beyond the time limit is invalid. A notice without the mandatory attachment is procedurally defective. Both grounds belong in the reply itself and should be raised clearly.
Step 7: File the Complete Response Before the Deadline
Submit the full reply, with all supporting documents, before the deadline stated in the notice. A late or incomplete response weakens the assessee’s procedural position in a way that is difficult to recover from. If additional time is genuinely needed, apply to the AO for an extension before the deadline lapses. An ignored Section 148A notice leads directly to a Section 148A(3) order against the assessee and a formal Section 148 reassessment notice.
Can a Section 148A Notice Be Challenged?
Not every Section 148A notice is legally valid. Taxpayers have specific, well-recognised grounds on which a notice can be challenged, and those grounds can be raised within the reply itself, without waiting for the Section 148A(3) order to be passed.
Recognised Grounds for Challenge
- Notice issued beyond the applicable time limit under Section 148A
- Specific information not attached to the notice as required by Section 148A(1)
- Section 148A(3) order passed without prior approval of the specified authority under Section 151
- Information relied upon is factually incorrect or was already addressed in a prior assessment
- Income alleged to have escaped assessment was already declared and taxed
- Mandatory procedural steps under Section 148A not followed in the correct sequence
Each of these grounds has been recognised in case law and in the statutory framework. A notice that fails on any one of them is challengeable before the AO and, if necessary, before a higher appellate authority.
What Happens if the AO Passes a Section 148A(3) Order Against You?
If the AO, after reviewing the reply, concludes it is a fit case for reassessment, a Section 148A(3) order is passed and a Section 148 notice follows. That Section 148 notice must be accompanied by a copy of the Section 148A(3) order. Without that copy, the Section 148 notice itself is defective.
At that stage, the assessee must file a return of income for the relevant assessment year within the period specified in the notice, not exceeding three months from the end of the month in which it is issued. The reassessment then proceeds under Section 147.
What Happens if You Ignore a Section 148A Notice?
Ignoring a Section 148A notice does not pause the process. It removes the assessee’s only statutory opportunity to prevent reassessment before it formally begins. Every stage that follows an ignored notice is more expensive, more complex, and carries greater legal exposure than the stage before it.
The AO Proceeds on Available Material Alone
Where no reply is filed, the AO proceeds to pass the Section 148A(3) order on the basis of the material already available, without any input from the assessee. An order passed in those circumstances is almost certain to treat the case as fit for reassessment. The assessee’s silence is taken as an inability to explain the discrepancy.
Section 148 Reassessment Notice Is Issued
Once the Section 148A(3) order is passed, a Section 148 notice follows. The assessee must then file a full return of income for the relevant assessment year within the period specified in the notice. If the reassessment under Section 147 confirms that income escaped assessment, the consequences are significant and operate across three separate provisions:
- Section 234A: Interest at 1% per month or part of a month for delay or default in filing the return required in response to the Section 148 notice. This runs from the day after the filing deadline to the date the return is actually submitted.
- Section 234B: Interest at 1% per month or part of a month for shortfall or default in payment of advance tax on the newly assessed income. Since the escaped income was never declared, advance tax was never paid on it, making this interest charge automatic on any additional demand raised.
- Section 270A: Governs penalties on the tax shortfall itself, with the rate determined by the nature of the discrepancy:
- Under-Reporting: If your assessed income is higher than the income you reported because of an omission or calculation error, without evidence of deliberate concealment, you may be liable to a penalty equal to 50% of the tax on the under reported income.
- Misreporting: If the under reported income resulted from deliberate actions such as misrepresenting facts, suppressing transaction records, making false entries, or claiming unsubstantiated expenses, the penalty increases to 200% of the tax on the under reported income.
Prosecution Risk Under Section 276C
Where the ITD determines that the assessee wilfully attempted to evade tax, prosecution proceedings can be initiated under Section 276C alongside penalty proceedings. Conviction carries imprisonment and a fine. The notice that was ignored at the Section 148A stage was the last point at which the process could have been stopped without criminal exposure.
Ignoring a Section 148A notice is the one decision that removes every option available to you. The good news is that if you have the right transaction data and documentation in place, responding is far more simple than it appears, and that is precisely where KoinX helps.
How KoinX Can Help When You Receive a Section 148A Notice for Crypto?
A Section 148A notice for crypto is fundamentally a data problem. The ITD holds a gross transaction figure from AIS or SFT filings. The assessee holds the transaction-level records that explain how that figure reduces to a taxable amount. The gap between those two positions is where notices are won or lost, and closing that gap requires accurate, complete transaction data across every platform used during the assessment year. This is where KoinX comes in handy. It is a global crypto tax platform built to consolidate that data and generate the transaction-level documentation a Section 148A response requires. Here’s what it offers:
Connect 800+ Exchanges, Wallets and Blockchains in One Place
KoinX connects with over 800 exchanges, wallets, and blockchains, including Indian platforms such as CoinDCX and WazirX, foreign platforms such as Binance and Bybit, and on-chain wallet addresses across major networks. For a trader who used multiple platforms during the assessment year in question, this means every transaction, buy, sell, swap, transfer, and receipt, is pulled into a single consolidated view without manual CSV downloads or data reconciliation errors.
Transaction-Level Schedule VDA Reports for Every Assessment Year
KoinX generates transaction-level Schedule VDA reports for past assessment years, not just the current filing period. For a Section 148A response, the most critical document is a reconciliation between the ITD’s AIS gross volume and the assessee’s declared net gain. KoinX produces that reconciliation at the individual transaction level, with acquisition dates, disposal dates, cost of acquisition in INR, and the resulting gain or loss, precisely the format required to address an AIS mismatch allegation.
P2P and Foreign Exchange Documentation Support
For P2P transactions and foreign exchange activity, the two categories most commonly flagged in crypto-related Section 148A notices, KoinX imports transaction data directly from connected platforms and generates statements that include trade dates, INR FMV at each date, counterparty information where available, and the cost basis for every disposal. These statements form the documentary foundation of a response to an unexplained credit flag or a foreign transaction allegation.
Expert Notice Response Support
If the notice has already arrived and you need professional guidance on how to respond, KoinX connects you with crypto tax professionals who specialise in VDA-related notice responses. From preparing the AIS reconciliation to drafting the factual reply and identifying procedural grounds for challenge, expert support covers every stage of the Section 148A response process.
A Section 148A notice is time-bound and the response window is short. Get started with KoinX today and ensure your transaction data is complete, reconciled, and ready to support a thorough reply.

Conclusion
A Section 148A notice is not a final verdict, it is a procedural checkpoint that the law built in specifically to protect taxpayers. The ITD must share what it found, the assessee must be heard, and a formal order must be passed before reassessment can begin. That window exists for a reason. A well-documented, timely response that reconciles the AIS gross figure against declared Schedule VDA income, addresses the correct data source, and raises any procedural grounds is often enough to stop the process before Section 148 is ever triggered.
That said, building that response requires complete transaction data, and that is where KoinX comes in. KoinX consolidates your entire crypto transaction history across every exchange, wallet, and blockchain into a single, reconciled report that maps directly to what the ITD expects to see. Sign up today and ensure your reply is built on accurate records, not gaps.
Frequently Asked Questions
I Received a Section 148A Notice but I Did Declare My Crypto Gains in Schedule VDA. What Do I Do?
Do not ignore the notice even if you believe your filing was correct. The ITD’s AIS figure is typically a gross transaction volume, not a net gain. If your declared Schedule VDA gain is smaller than the AIS figure, that discrepancy is the trigger. Prepare a transaction-level reconciliation showing exactly how the gross volume reduces to the declared net, attach it to your reply, and file before the deadline.
How Does the ITD Know About My Trades on Binance if I Never Used an Indian Exchange?
Under Section 148(3)(iii), the ITD can use information received under tax treaties, Section 90 or Section 90A, to justify reopening an assessment. India’s treaty network and OECD-aligned data sharing agreements provide transaction-level information from foreign jurisdictions. From 1 September 2024, Section 133A survey data from entities related to foreign platforms is also a valid source. Foreign exchange activity is not invisible to the ITD.
My Section 148A Notice Mentions an AIS Mismatch, but the AIS Figure Is My Gross Trading Volume, Not My Net Gain. Is This a Valid Basis?
Yes, it is a valid basis, but it is also the most common and most resolvable category of crypto-related Section 148A notice. The ITD’s SFT data captures gross transaction volume. Your declared Schedule VDA figure is the net taxable gain. A transaction-level reconciliation that bridges the two, with cost of acquisition documented for each disposal, is typically sufficient to demonstrate that income has not escaped assessment.
I Ignored the Notice and Now Have a Section 148 Reassessment Notice. Is It Too Late to Respond?
It is not too late, but the position is now more difficult. At the Section 148 stage, the assessee must file a full return of income for the relevant assessment year within the period specified in the notice. The reassessment that follows can still be contested, but the opportunity to prevent it at the Section 148A stage is gone. Consult a qualified CA immediately and file the required return within the notice period.
Can I File an Updated Return Under Section 139(8A) Instead of Responding to the Section 148A Notice?
In certain circumstances, filing an updated return under Section 139(8A) may address the underlying income gap that triggered the notice. However, it must not be done without first evaluating the implications on the reassessment proceedings. Filing an updated return after receiving a Section 148A notice does not automatically close the Section 148A process. Seek professional advice before choosing this route.
I Did Several P2P Trades and the ITD Is Calling Them Unexplained Cash Credits Under Section 68. What Documents Do I Need?
For each P2P transaction flagged under Section 68, you need counterparty KYC documentation, platform confirmation of the trade, the INR FMV on the transaction date, and the cost of acquisition for the crypto transferred. Bank statements showing the INR receipt and any Form 26QE filings are also required. The response must establish the source, nature, and taxability of each flagged credit with documentary evidence, not a general assertion.
The Section 148A Notice Does Not Mention What Specific Information the ITD Is Relying On. Is That Valid?
No. Under Section 148A(1), the show cause notice must be accompanied by the specific information suggesting income has escaped assessment. A notice that does not attach or identify that information is procedurally defective. You can raise this deficiency directly in your reply and request that the AO supply the information before requiring a response. This procedural ground, if established, can invalidate the notice entirely.
