India has topped the Chainalysis Global Crypto Adoption Index for three consecutive years. Over 70% of that trading volume sits on offshore platforms, Binance, Bybit, and Kraken, precisely because they sit outside India’s domestic tax net. However, that window is closing now, and it is closing on a fixed date. All thanks to CARF. The Crypto-Asset Reporting Framework (CARF) is an OECD-led system that requires crypto exchanges to automatically share user transaction data with tax authorities across borders.
From April 2027, India will officially become a part of CARF. Hence, it will automatically receive transaction-level data on every Indian investor active on a participating foreign exchange. The CBDT has officially confirmed this commitment in September 2025. As of January 2026, data collection has already begun under CBDT Notification No. 19/2026, which brought crypto assets into India’s Common Reporting Standard framework.
This does not call for a future risk. However, it can be a present one if your FY 2025-26 foreign exchange activity does not match your ITR. This article explains what CARF is, what India will receive, and what you need to do before that data arrives.
Key Takeaways
- CARF is an OECD framework requiring crypto exchanges to report user transaction data to tax authorities automatically, across borders.
- India committed to CARF in September 2025. Cross-border data exchange begins April 1, 2027.
- CBDT Notification No. 19/2026 expanded CRS reporting to include crypto assets from January 1, 2026. Data collection has already started.
- Foreign exchanges serving Indian users are required to collect PAN or TIN and report annually to their domestic authority, which forwards the information to India.
- Estimated untaxed offshore crypto flows from Indian investors: INR 5,000 crore annually, the precise gap CARF is designed to recover.
- Budget 2026 penalties for non-reporting: INR 200 per day for late filings; INR 50,000 for incorrect disclosures, both effective April 1, 2026.

What Is CARF and Why Did the OECD Create It?
Before CARF, we had the CRS. The Common Reporting Standard (CRS) is a framework that requires financial institutions to identify and report accounts held by foreign tax residents. It works when there is a custodian, a bank, or a broker sitting between the user and their assets.
But then came cryptocurrencies that dismantled this assumption. Assets held in self-hosted wallets have no custodian. Swaps on decentralised exchanges leave no account trail. Therefore, the CRS framework, designed in 2014, lacked a mechanism to capture transactions in which the reporting intermediary simply did not exist.
What CARF Does Differently?
CARF is event-driven rather than account-based. It focuses on the transaction itself, the exchange, the transfer, the retail payment, rather than an account balance at year-end. Every qualifying transaction by a user in a participating jurisdiction is a reportable event.
Reporting Crypto-Asset Service Providers (RCASPs), a term covering centralised exchanges, brokers, and dealers, capture transaction data at the point of execution. They report it annually to their domestic tax authority. That authority forwards it automatically to every country where the user holds tax residence.
What Data RCASPs Must Collect and Report?
RCASPs are required to collect and report two categories of information: user identity and transaction records. Together, these give the CBDT a complete picture of who traded, what they traded, and at what value.
User Identity Data:
- Full name, residential address, and date of birth
- Taxpayer Identification Number, PAN for Indian residents
- Country of tax residence, verified through KYC documentation
Transaction Records:
- Type of crypto asset involved in each transaction
- Gross amount received or paid per transaction
- Fair market value in fiat currency at the time of the transaction
- Whether the transfer involved a self-hosted or third-party wallet
- Wallet address, where the transfer was made to an unhosted wallet
The OECD updated the CARF XML schema in August 2025 to standardise data formats across all participating jurisdictions, ensuring consistent reporting regardless of the exchange or the country involved.
Which Assets Fall Under CARF?
CARF draws a clear line between assets that are in scope and those that are not. The determining factor is whether the asset can be used for payment or investment purposes.
In Scope:
- Bitcoin, Ether, and other major cryptocurrencies
- Stablecoins, including USDT and USDC
- Tokenised securities
- Certain NFTs used for investment or payment purposes
Out of Scope:
- Central bank digital currencies (CBDCs)
- Closed-loop electronic money products not used for payment or investment
- Crypto assets that an RCASP has adequately determined cannot be used for either purpose
The practical effect is straightforward. Virtually every asset traded on a major centralised exchange falls within scope. Institutional CBDCs and restricted-use tokens do not.
How India Got To Adopt CARF?
India’s adoption of CARF was not a sudden policy shift. Each step in India’s crypto compliance architecture addressed a specific gap that the previous one left open. Understanding that sequence matters because it explains why investors who assumed offshore activity was invisible have been progressively wrong and will be entirely wrong from April 2027.
Layer 1: TDS Under Section 194S (2022)
The 1% TDS under Section 194S was never intended to collect the full tax. It was designed to create a transaction trail. Every transfer above INR 10,000 annually that goes through a registered Indian exchange leaves a record against the seller’s PAN.
The gap it left was significant. Foreign exchanges, Binance, Bybit, and Kraken, were not registered with India’s Financial Intelligence Unit before 2024. Trades on those platforms generated no TDS record. For investors who moved offshore, the ITD’s visibility dropped sharply.
Layer 2: Section 285BAA Domestic Reporting (February 2025)
Section 285BAA, introduced in Budget 2025 in February 2025, requires registered Indian crypto exchanges to report transaction data to the ITD from April 1, 2026. This formalised what TDS reporting had started, a structured, mandatory data pipeline from domestic platforms to the CBDT.
Budget 2026 added penalties to reinforce it. Entities that fail to submit required statements face a penalty of INR 200 per day. Incorrect or unrectified disclosures incur a flat penalty of INR 50,000. Both provisions took effect from April 1, 2026.
Layer 3: CBDT CRS Expansion to Crypto (March 2026)
CBDT Notification No. 19/2026, issued on March 5, 2026, but effective from January 1, 2026, amended Rules 114F, 114G, and 114H of the Income-tax Rules 1962. These amendments expanded the definition of financial assets under the Common Reporting Standard to formally include crypto assets, CBDCs, and electronic money products.
A new Rule 114G(6A) was introduced alongside the expansion. It clarifies that where a transaction is already captured under CARF, it need not be reported again under CRS. This avoids duplicate reporting and signals that the CBDT has designed both frameworks to operate as a single, coordinated system rather than two parallel ones.
Layer 4: Adoption of CARF International Data Exchange (April 2027)
CARF is the fourth layer, and the one that makes the previous three globally enforceable. From April 2027, data collected by foreign exchanges on Indian users will automatically flow to the CBDT through the participating jurisdiction’s tax authority.
India confirmed its alignment with the OECD CARF framework in September 2025, joining 52 jurisdictions committed to first exchanges by 2027. And, the technical architecture for data transmission is being finalised. The CBDT has set April 1, 2027, as the domestic enforcement start date.
What Will India Receive Under CARF From April 2027?
CARF does not deliver a summary. It delivers structured, transaction-level data on every Indian PAN holder who traded on a participating platform, including the exchange they used, the assets they traded, the amounts involved, and the wallet addresses they transacted with.
Which Exchanges Will Report to India?
Any exchange registered as an RCASP in a CARF-participating jurisdiction and serving Indian users falls within scope. The list below covers the major platforms most Indian investors use, along with the specific reporting obligation each carries.
- Binance: Operates through EU-licensed entities in Malta and Lithuania, placing it under DAC8 reporting obligations from January 2026.
- Coinbase: Subject to both US domestic crypto reporting rules and DAC8 for its European operations, covering Indian users on both fronts.
- Kraken: Has publicly confirmed CARF compliance preparation and operates within multiple CARF-participating jurisdictions.
- Bybit: Registered across several jurisdictions and subject to CARF obligations wherever it holds a licence in a participating country.
- KuCoin: Registered with India’s FIU following the 2024 ban and additionally subject to domestic reporting under Section 285BAA.
What the ITD Will Do With the Data?
The ITD will cross-reference CARF data against ITR filings and AIS entries. Where a taxpayer reported no foreign exchange income but CARF shows INR 12,00,000 in Binance transactions during FY 2026, the discrepancy triggers automated scrutiny.
The ITD has already demonstrated its capacity to cross-reference data at scale. Notably, the recent 44,000 notices issued in FY 2024-25 were generated through AIS and TDS cross-referencing alone.
With CARF data added, the matching exercise becomes far more complete. Every trade on a participating foreign platform will have a corresponding ITR entry, or it will not, and the ITD will notice.
How CARF Interacts With AIS and Form 26AS?
CARF data received by the CBDT will feed into the Annual Information Statement (AIS). Investors will be able to see what the ITD holds before they file. The AIS already captures TDS deducted by Indian exchanges under Section 194S. From 2027, it will also reflect transactions reported by foreign exchanges under CARF.
This creates a specific compliance obligation: the AIS figure and the Schedule VDA figure must reconcile. Where they do not, the investor needs documentation explaining the difference before the ITD asks for it.
How Will CARF Affect Indian Crypto Investors?
CARF does not create a uniform risk for every Indian investor. The level of exposure depends entirely on what was done, on which platforms, and whether the returns filed reflect it. An active trader on Binance faces a different position than someone who sold ETH once on Kraken and declared it correctly. Hence, understanding who and how CRAF will apply in India becomes important. So let’s check:
Active Traders on Foreign Exchanges
A trader executing dozens of swaps monthly on Binance generates a substantial CARF dataset. Every trade, token-to-token, fiat-to-crypto, leveraged position exit, is a reportable event. The cumulative fair market values across a financial year will arrive in the CBDT’s systems as a single, structured file.
If the corresponding Schedule VDA entries in the ITR do not account for each of those transactions, the AIS mismatch will be significant. The ITD does not need to investigate individually. The data infrastructure does the matching automatically.
Passive Investors, One or Two Transactions
A passive investor who bought ETH on Kraken, held it for twelve months, and sold it once faces a narrower but still real exposure. Both the purchase and the disposal are reportable events under CARF. If the disposal was declared correctly in Schedule VDA, there is no issue.
If the investor did not declare it, because Kraken did not deduct Indian TDS and no Indian exchange reported the trade to the ITD, the gap will appear when the CARF data arrives. The remedy is to report it to the ITD, in a revised return, while the window remains open.
Mistake Makers, Already Filed Incorrectly or Not at All
For investors who filed nothing on foreign exchange income or declared it under the wrong head, the period between now and April 2027 is the most valuable window. A revised return filed under Section 139(5) before the ITD issues a notice substantially reduces penalty exposure.
Once CARF data arrives and the ITD matches it against a nil return or an incorrect one, the voluntary disclosure advantage disappears. The notice arrives, the penalty clock starts, and the investor is responding rather than acting.
P2P Traders and the Section 68 Compounding Risk
P2P traders who conducted transactions through foreign platforms without verified counterparty PAN details carry a specific risk beyond the standard under-reporting penalty. Where the ITD cannot verify the counterparty in a transaction flagged by CARF, it may classify the entire transaction value as an unexplained cash credit under Section 68, taxable at 60%, not just the gain at 30%.
CARF data confirms the transaction occurred. The absence of counterparty KYC becomes the additional liability, not a mitigating factor.
What Should Indian Investors Do Before April 2027?
The April 2027 data exchange is confirmed. In this scenario, what remains within an investor’s control is how prepared they are when the CBDT receives that first file. There is a specific set of actions, each with a narrowing window, that separates investors who file correctly from those who receive a notice.
Step 1: Download and Consolidate Transaction Records
Begin with every foreign exchange used in FY 2024-25 and FY 2025-26. Most major platforms provide downloadable transaction histories in CSV format. Export the full year, not just trades. Include deposits, withdrawals, staking receipts, and any fiat conversions.
Consolidate the exports into a single timeline. The ITD will receive a complete dataset. Reviewing the same data in advance is the only way to identify discrepancies before they become notices.
Step 2: Reconcile Against AIS Now, Not After the Notice
Log in to the income tax portal and download your AIS for FY 2024-25 and FY 2025-26. Cross-reference the figures against your consolidated transaction history. AIS currently captures TDS from Indian exchanges and Specified Financial Transactions (SFT) data. From 2027, it will also include CARF-sourced foreign exchange data.
Where the AIS figure is lower than your actual transaction volume, because foreign trades have not yet entered the system, identify each unreported item and prepare the corresponding Schedule VDA entry.
Step 3: File a Revised Return Under Section 139(5) if Needed
If your ITR for FY 2024-25 or FY 2025-26 does not reflect all foreign exchange income, file a revised return under Section 139(5) before the ITD raises a notice. A voluntary revision before notice is treated significantly more leniently than a post-notice correction.
The revised return window under Section 139(5) stays open until two years from the end of the relevant assessment year, or until the assessment is completed, whichever is earlier. For FY 2024-25 (AY 2025-26), that window closes by March 31, 2027, one month before CARF data arrives.
Step 4: Verify PAN or TIN Registration on Foreign Exchanges
CARF data is linked to your taxpayer identification number. If your PAN or TIN is incorrectly registered, or not registered at all, on a foreign exchange, the reporting chain breaks. That is not a protection; it creates an additional compliance risk under PMLA and may attract scrutiny under Section 68.
Log in to every foreign exchange account and confirm that the PAN or TIN on file matches your Indian income tax records exactly. Update it where it does not.
Step 5: Maintain FMV Records for Every Receipt and Disposal
CARF data includes fair market values at the time of each transaction. The ITD will use these values to calculate the taxable gain or income. If your own FMV records differ from the values in the CARF dataset because you used a different pricing source, you need documentation to support your calculation.
Maintain a dated record of the INR FMV for every crypto receipt and disposal. Exchange APIs, CoinGecko, or CoinMarketCap historical data are all acceptable sources. The record-keeping obligation sits with the investor, not with the exchange.
How Will CARF Affect Indian Crypto Exchanges?
CARF is not only an investor compliance issue. It will place obligations on the exchanges as well. Domestic Indian platforms already reporting under Section 285BAA will see their obligations expand into an international data exchange layer. Foreign exchanges serving Indian users face a new category of regulatory requirement that did not exist before.
What Domestic Indian Exchanges Must Do?
Indian exchanges registered with the FIU, CoinDCX, Mudrex, and CoinSwitch are already capturing and reporting transaction data under Section 285BAA and the TDS framework. Their CARF obligation adds a data standardisation layer. User data must be formatted to OECD XML schema standards for the international exchange to function.
These exchanges must also implement enhanced due diligence under the amended Rules 114F, 114G, and 114H. Self-certification of tax residency, collection of TIN or PAN, and confirmation of account type are now mandatory for all reportable users.
What CARF Means for the Future of Crypto Tax Compliance in India?
CARF does not complete India’s crypto compliance architecture. It activates it globally. The domestic layers, TDS, Section 285BAA, and the CRS expansion were effective within India’s borders. CARF is the mechanism that extends those layers to every participating jurisdiction where Indian investors trade.
Will CARF Replace the 1% TDS?
Some industry voices argued that CARF’s adoption should lead to the removal of the 1% TDS under Section 194S. The logic is that if transaction data arrives automatically from exchanges, there is no need for a domestic advance tax mechanism to create a trail.
However, the CBDT has not indicated any intention to remove TDS. The two mechanisms serve different functions. TDS creates a real-time domestic record at the point of transaction. CARF delivers an annual, structured, cross-border dataset. Until CARF demonstrates equivalent or superior visibility for domestic trades, retaining TDS alongside it is the more cautious regulatory position.
How CARF Aligns With India's G20 Presidency Commitments?
The G20 Leaders’ Declaration from New Delhi in September 2023 explicitly noted the aspiration of many jurisdictions to launch CARF exchanges by 2027. India’s CARF commitment is therefore a direct product of its own G20 presidency, not a response to external pressure, but a policy position India helped shape.
This alignment matters for investors because it signals that CARF is not a provisional measure. It is the outcome of a multi-year, multilateral commitment that India initiated at the highest level of international economic policy.
The transition from domestic enforcement to global data exchange is the final step in India’s crypto tax framework. For investors who have kept accurate records, filed correctly, and verified their foreign exchange registrations, CARF changes nothing operationally. For those who have not, having complete transaction records and a consolidated tax computation ready before April 2027 is not optional, it is the difference between a clean filing and an expensive notice. KoinX is built precisely for that consolidation.
How KoinX Helps Indian Investors Prepare for CARF?
When your trades are spread across Binance, Bybit, Kraken, and a domestic exchange, consolidating four transaction histories into a single ITR-ready Schedule VDA computation and matching each against AIS is not a manual task. CARF adds a fifth dataset to that reconciliation. KoinX is a global crypto tax platform trusted by over 1.5 million users across 100+ countries, with 800+ exchange and wallet integrations, built to handle exactly this.
Full Transaction Import From 800+ Exchanges Including Foreign Platforms
KoinX connects directly to Binance, Bybit, Kraken, Coinbase, and 800+ other exchanges and wallets via API and CSV import. Every trade, transfer, staking receipt, and fiat conversion is pulled into a single timeline automatically. No manual CSV merging. No missed transactions. The full dataset that CARF will eventually report to the CBDT is visible to you first.
AIS Reconciliation Before CARF Data Arrives
KoinX computes the gross transaction volume that the ITD will see in your AIS and compares it against your declared Schedule VDA figures. Discrepancies are flagged before you file, giving you time to prepare reconciliation documentation or revise your return before any notice is raised. This is the most important step an investor can take before April 2027.
ITR-Ready Reports for Foreign Exchange Income
KoinX generates ITR-3 and ITR-2 ready Schedule VDA reports that map every foreign exchange transaction to the correct income head and disposal entry. FMV values are calculated at the date of each transaction using verified pricing data. The output matches the structure the ITD expects, including the figures CARF will independently confirm.
CARF-Ready Record Keeping and FMV Documentation
Every transaction imported into KoinX is time-stamped with the INR FMV at the date of the event, sourced from verified market data. This creates the audit-ready FMV record that the ITD will cross-reference against CARF data. If the CBDT questions a cost basis or disposal value, the documentation is already structured and ready to produce.
The April 2027 data exchange cannot be delayed. Your preparation for it can begin today. Generate your CARF-ready crypto tax report on KoinX and ensure your FY 2025-26 filing reflects every transaction before the ITD receives it from the exchange.
Conclusion
CARF does not introduce a new tax. It introduces visibility that did not exist before. From April 2027, every trade executed on a foreign exchange from January 2026 onwards becomes part of a dataset that the CBDT will receive automatically. Investors with undeclared offshore income have one remaining window: a revised return under Section 139(5), before that data arrives and the voluntary disclosure advantage disappears.
Getting that return right requires complete, reconciled transaction data from every platform used. KoinX consolidates your foreign exchange history, matches it against your AIS, and generates ITR-ready Schedule VDA reports. Get registered on KoinX today so your filing reflects what the CBDT will receive before they receive it.
Frequently Asked Questions
My Foreign Exchange Already Has My PAN. Does That Mean CARF Has My Data From Before 2026?
Not automatically. CARF data collection formally begins from January 1, 2026. Transactions before that date are not part of the standard CARF exchange cycle. However, the ITD retains the authority to issue collective information requests to exchanges for earlier periods where it has reason to believe income escaped assessment. Prior activity is not protected, it is simply not in the first automatic exchange.
I Traded on Binance in FY 2024-25 and Declared Nothing. What Is My Exposure Now?
Your FY 2024-25 data is not in the first CARF exchange, but Binance has been registered with India’s FIU since March 2024 and is subject to domestic reporting obligations from that point. More significantly, if your FY 2025-26 CARF data reveals consistent offshore activity, the ITD will look backwards. A revised return for FY 2024-25 under Section 139(5) is the most effective step available before March 31, 2027.
Will CARF Data Be Used for Retrospective Assessments, or Only From FY 2026-27 Onwards?
CARF’s automatic exchange covers calendar year 2026 activity, broadly aligned with FY 2025-26. The ITD can use this data to support retrospective assessments of earlier years under Section 148A, where income above INR 50 lakh escaped assessment. CARF data for a later year can establish the pattern and intent needed to justify reopening an earlier one.
I Use a Hardware Wallet and Move Crypto Off Exchanges. Will CARF Still Capture My Activity?
CARF captures the transfer from the exchange to your unhosted wallet, including the wallet address. What happens inside the wallet after the transfer is not directly reportable under CARF. However, on-chain activity is publicly traceable through blockchain analytics. The ITD has been developing blockchain forensics capacity. Moving assets off-exchange narrows, but does not eliminate, the ITD’s visibility.
Does CARF Replace the 1% TDS Under Section 194S?
No. The CBDT has not announced any intention to remove TDS alongside CARF. They serve different functions. TDS creates a real-time domestic trail at the point of transaction and delivers an annual cross-border dataset. Both are likely to coexist until the ITD is satisfied that CARF delivers equivalent domestic visibility. Investors should continue complying with TDS obligations regardless of CARF.
