When it comes to OTC crypto trading, India’s crypto market has a problem most retail-focused guides ignore. The country’s 1% TDS on every crypto transaction under Section 194S means a trader selling a ₹1 crore Bitcoin position across ten exchange orders pays ₹1 lakh in TDS hits before accounting for a single rupee of profit tax. That’s an execution problem, not a tax strategy problem.
OTC crypto trading in India exists for exactly this situation. Fewer, larger settlements. Same total tax liability. Far less friction on large orders. But the market runs quietly, often informally, and most guides skip the parts that matter: what it costs, who regulates it, and where it breaks down.
Key Takeaways
- OTC crypto trading in India is legal, but no specific OTC crypto law exists. Desks must be registered with FIU-India under PMLA from March 2023.
- Cost is a spread (typically 0.1%–0.5% on liquid assets), not a line-item fee. At large trade sizes, this is often cheaper than exchange slippage.
- 1% TDS under Section 194S applies to OTC trades just as it does to exchange trades. FIU-registered desks handle deduction; unregistered desks often don’t, leaving you liable.
- Every OTC trade must be individually reported in Schedule VDA in your ITR. The trade confirmation document from your desk is your source record.
- Verify FIU registration at fiuindia.gov.in before sending any funds. Trading through an unregistered desk creates PMLA exposure for you, not just the desk.
What Is OTC (Over-the-Counter) Crypto Trading in India?
What is OTC crypto trading? OTC crypto trading is the buying or selling of cryptocurrency directly through a broker or dedicated desk, outside a public exchange order book. In India, it is primarily used for large INR-to-crypto or crypto-to-INR conversions where exchange slippage, or repeated TDS hits across multiple smaller trades, would make public exchange trading more expensive and more administratively burdensome.
The mechanics are straightforward. You contact the desk, specify the asset and amount, receive a locked price quote (called a Request for Quote, or RFQ), accept it, and settle via bank transfer or crypto wallet. No open order book. No visible footprint in the market.
For a deeper primer on how OTC markets work globally across stocks, derivatives, and currencies, see OTC Trading Explained: A Complete Guide. This article focuses specifically on how OTC crypto trading operates within India’s tax and regulatory environment.
Who Actually Uses a Crypto OTC Desk in India?
Four types of users drive the majority of OTC crypto volume in India. Each has a specific reason a public exchange doesn’t work well for them.
1. Founders and crypto-native startups
Companies that raised funds in USDT or earn protocol revenue in crypto regularly need to convert large amounts to INR for payroll, vendor payments, and operations. Converting ₹50 lakh across dozens of exchange trades doesn’t just create slippage.
It creates dozens of TDS deduction events, each requiring documentation for ITR filing. A single OTC trade consolidates that into one settlement and one TDS certificate.
2. HNIs exiting large positions
Someone holding Bitcoin acquired between 2019 and 2021 who wants to liquidate faces a different problem. On a public exchange with a thin order book, a ₹2 crore sell order is visible to market makers and algorithmic traders before it fully executes. The act of placing the order signals intent and the price moves against the seller mid-fill. OTC removes that signal entirely.
3. Mining operations and staking validators
Entities earning crypto continuously need regular, predictable INR conversion at volume. OTC desks offer scheduled settlement windows, predictable spreads, and direct bank transfers via RTGS. Retail exchange UX isn’t built for this.
4. Corporate treasuries and family offices
Companies exploring crypto treasury allocation or liquidation need audit-ready documentation, INR settlement via RTGS, and a registered counterparty name for board-level compliance records. An informal exchange account doesn’t satisfy any of that.
What Does OTC Crypto Trading Actually Cost in India?
This is the section most OTC guides get wrong or skip. The cost structure is not what retail traders expect.
1. The spread, not a fee
OTC desks don’t charge a visible trading fee. Their margin is embedded in the quoted spread: the gap between what they buy at and what they sell at. On liquid assets like Bitcoin, Ethereum, and USDT, Indian OTC desks typically operate at spreads of 0.1% to 0.5%. On less liquid altcoins, spreads can reach 1% to 3% or higher.
That sounds expensive until you compare it to the alternative. A ₹1 crore Bitcoin buy on a public exchange with limited order book depth can experience 0.8% to 2% price impact across multiple fills. At that scale, a 0.3% OTC spread is the cheaper execution, even before factoring in the market signalling cost described above.
2. Crypto TDS India: the cost most OTC articles ignore
Section 194S of the Income Tax Act requires 1% TDS on INR settlements from crypto transactions above ₹10,000 (₹50,000 for non-specified persons). On a ₹1 crore OTC trade, that’s ₹1 lakh withheld at source.
This is not optional and doesn’t disappear because you used an OTC desk instead of an exchange. What changes is who handles it. FIU-registered desks deduct TDS and deposit it with the government on your behalf, then issue you a TDS certificate (Form 16A or equivalent). Unregistered desks frequently skip this step, leaving you to self-declare and prove compliance when the Income Tax Department sees the INR credit in your bank account.
Use the India Crypto Tax Calculator to model the TDS impact on your specific settlement amount before you initiate a trade.
3. Minimum trade sizes
Most Indian OTC desks require a minimum trade of ₹25 lakh to ₹50 lakh.
Examples: SunCrypto’s OTC Desk handles INR settlement via IMPS, NEFT, and RTGS, with a separate deposit process from regular exchange orders.
Onramp Business OTC supports INR-to-crypto and crypto-to-INR with NEFT/RTGS settlement and targets institutional and HNI clients. CoinSwitch OTC Desk is positioned specifically for large-portfolio and treasury use cases.
Below the ₹25 lakh threshold, slippage on a standard crypto trading platform is unlikely to cost more than the OTC process overhead. OTC is not for every trade.
4. The RFQ expiry problem
A quoted OTC rate is typically locked for 30 to 120 seconds. If you miss the window because of an internal approval delay, a bank RTGS cut-off time (typically 4:30 PM on working days), or a slow wire confirmation, you re-quote at whatever the market has moved to.
For large trades requiring treasury sign-off or board approval, this is a real execution risk that needs to be planned for before the trade is initiated, not during it.
| Cost Component | Typical Range | Notes |
| OTC spread (BTC, ETH, USDT) | 0.1% to 0.5% | Built into quoted price, not a separate fee |
| OTC spread (altcoins) | 1% to 3%+ | Wider due to lower liquidity |
| TDS (Section 194S) | 1% of INR settlement | Applies regardless of exchange or OTC route |
| Exchange slippage (₹1Cr order) | 0.8% to 2% | Variable; depends on order book depth |
| Minimum ticket size | ₹25L to ₹50L | Below this, exchange is more practical |
How India’s Tax Rules Apply to OTC Crypto Trades
The India Crypto Tax guide covers the full filing process. This section applies those rules to OTC trades specifically, where several points are less obvious.
1. 30% flat tax on gains
Section 115BBH applies regardless of whether you traded on a public exchange or through an OTC desk. Holding period doesn’t matter. Losses from other VDA trades cannot offset gains here.
2. Schedule VDA filing
Every OTC trade must be reported individually in Schedule VDA in your ITR: asset name, quantity, INR value, date, and gain or loss. The trade confirmation from your desk is your primary source record. Without it, you’re reconstructing the transaction from bank statements and chat screenshots during a scrutiny.
3. The TDS compliance gap
From March 2023, all entities offering crypto services in India must register with FIU-India under PMLA. Registered desks handle TDS automatically. Many informal OTC operators don’t. The Income Tax Department sees the INR credit in your bank account either way. The burden of proving TDS compliance falls on you.
What Can Go Wrong: India-Specific OTC Risks
These aren’t generic counterparty risk warnings. They’re specific to how India’s OTC market actually operates right now.
1. The unregistered desk problem
There’s no publicly maintained list of “approved” crypto OTC brokers in India beyond FIU-India registration. Dozens of informal operators exist, some running WhatsApp groups, some posting in Telegram channels with rates that look 0.5% to 1% better than legitimate desks.
Trading through them isn’t just fraud exposure. Under PMLA, transacting through an unregistered reporting entity can create legal exposure for the customer, not only the operator.
2. Settlement timing versus crypto price movement
Indian OTC trades frequently settle via RTGS, which closes at 4:30 PM on working days. A large trade initiated at 2 PM may not settle until the next morning if the INR transfer misses the window. Crypto prices don’t pause overnight. Most OTC desks only guarantee the quoted rate for the RFQ window (30 to 120 seconds). After that, you re-quote at the current market price. Buyers and sellers both need to understand this before committing to a large trade late in the banking day.
3. The documentation gap
Registered exchanges automatically generate transaction records. OTC desks don’t report to your exchange account or generate an entry in your Annual Information Statement (AIS) the same way. If your desk doesn’t issue a formal trade confirmation covering asset, quantity, INR value, rate, date, and TDS amount, you have no clean source document for Schedule VDA. An Income Tax notice for unexplained INR credits becomes extremely difficult to defend without this.
4. The “better rate” scam
This pattern is specific to India’s informal OTC market. An operator advertises rates 0.5% to 1% above what legitimate desks quote. They ask for an INR transfer first. They either deliver crypto late or not at all. Legitimate desks make money on spreads. They don’t need to beat market rates to attract volume. If a quoted rate looks significantly better than what FIU-registered desks are offering, that gap is the risk premium you’re unknowingly paying.
5. No formal recourse
Unlike a banking fraud claim under RBI’s grievance framework or a SEBI-regulated platform dispute, OTC crypto trade disputes have no formal resolution mechanism in India. SEBI doesn’t cover crypto. RBI doesn’t cover crypto OTC. FIU-India handles AML enforcement, not customer disputes. Your only protection is choosing the right desk before the trade happens.
How to Verify a Crypto OTC Desk in India
Before sending any funds, check these five things. Each one takes a few minutes and removes the most common failure modes.
- FIU-India registration: Check fiuindia.gov.in for the desk’s registered entity name. If they’re not listed, stop.
- Registered legal entity: Ask for the desk’s CIN (Corporate Identification Number) and verify it at mca.gov.in. A desk without a verifiable Indian company registration is operating informally.
- Sample trade confirmation: Before sending money, ask to see the confirmation document they issue post-settlement. It should show: asset, quantity, INR value, rate, date and time, TDS amount, and the desk’s legal entity name. A screenshot from a chat app is not a trade confirmation.
- Rate lock process: Ask explicitly what happens if your INR transfer misses the RFQ window. Do they re-quote at the new market rate or honour the original? Get this in writing. The answer tells you immediately whether they’ve built for institutional clients or not.
- TDS certificate: Confirm they issue Form 16A or equivalent after each settlement. Without it, your Schedule VDA filing becomes your problem to solve without documentation.
Final Thoughts
OTC crypto trading in India is a legitimate execution method for a specific use case: large trades where exchange slippage or repeated TDS events on smaller orders would cost more than the OTC spread. It’s not a workaround, and it’s not a grey market. The tax obligations are identical to exchange trading. The documentation burden is, if anything, higher.
The risks are real but manageable. Use an FIU-registered desk. Get a formal trade confirmation before you consider the trade settled. Report every OTC trade in Schedule VDA. Plan your settlement timing around RTGS windows. And if a quoted rate looks too good relative to what registered desks are offering, that gap is not a bargain.
Frequently Asked Questions
Most Indian OTC desks start at ₹25 lakh to ₹50 lakh per trade. Global desks like Binance OTC and Kraken OTC typically require $50,000 to $100,000 equivalent. Below ₹25 lakh, a regular exchange is more practical.
Yes. No specific OTC crypto law exists, but all entities offering crypto services must register with FIU-India under PMLA from March 2023. Trading through an unregistered desk creates PMLA exposure for you. Verify at fiuindia.gov.in first.
FIU-registered desks deduct 1% TDS on INR settlements under Section 194S and deposit it with the government, issuing a TDS certificate. Unregistered desks frequently skip this. The Income Tax Department sees the INR credit in your bank account either way. The compliance burden falls on you if the desk doesn’t handle it.
P2P connects individual buyers and sellers for smaller amounts via UPI or bank transfer, with the platform holding crypto in escrow. OTC desks are professional intermediaries for large-volume trades with fixed pricing, RTGS/NEFT settlement infrastructure, formal documentation, and FIU compliance. P2P is for retail. OTC is for institutions and HNIs.
Verify FIU-India registration. Confirm a registered Indian legal entity with a verifiable CIN. Ask for a sample trade confirmation before sending funds. Confirm they issue TDS certificates. Clarify what happens if your bank transfer misses the RTGS cut-off window. Get all of this in writing before the first trade.
