What is Tax Loss Harvesting in Crypto?
Tax loss harvesting is a strategy where investors deliberately sell losing positions to realize losses, which can offset capital gains and reduce overall tax liability. For Indian crypto investors, this becomes particularly valuable given India’s 20% TDS rate on crypto trading gains and progressive income tax brackets.
Why It Matters for Indian Crypto Investors
Under India’s Income Tax Act:
- Section 43: Virtual digital assets are taxed as capital assets
- Section 49: Cost of acquisition includes both purchase price and transaction costs (fees, slippage)
- Section 194O: 1% TDS applies to crypto sales above ₹50,000 in a financial year
This means:
- A ₹1,00,000 profit is taxed at 20% long-term capital gains + 1% TDS (if applicable) = ₹21,000 tax
- If you harvest ₹80,000 in losses against this, your taxable gain drops to ₹20,000 = ₹4,200 tax
- Net savings: ₹16,800 per cycle
Tax Loss Harvesting Strategy: Step-by-Step
1. Identify Loss-Making Positions
Track coins trading below your buy price:
- Bitcoin entry: ₹40,00,000, current: ₹38,00,000 = ₹2,00,000 loss
- Ethereum entry: ₹2,00,000, current: ₹1,80,000 = ₹20,000 loss
2. Sell Before Year-End (March 31 in India)
Under Section 43, the transaction date (not settlement) determines the financial year for tax purposes. Sell before March 31 to realize the loss in the current fiscal year.
3. Rebuy After 30 Days (Wash Sale Caution)
While India doesn’t have explicit “wash sale” rules like the US, the Income Tax Department expects genuine realization of losses. Repurchase after 30 days to demonstrate a genuine trading decision.
4. Document Everything
- Purchase date and price (₹/crypto)
- Sale date and price
- Transaction fees and conversion losses
- Exchange receipts and bank statements
5. Offset Against Long-Term Gains
If you have LTCG (assets held >12 months):
- Long-term capital loss: ₹2,00,000 (as defined in Section 43)
- Long-term capital gain: ₹5,00,000
- Net LTCG: ₹3,00,000
- Tax at 20%: ₹60,000
Without loss harvesting: ₹1,00,000 tax
Practical Example for Indian Investor
Scenario: Priya bought ₹50 lakhs of crypto in Jan 2026.
| Asset | Buy Price | Current | Gain/Loss | Action |
|---|---|---|---|---|
| BTC | ₹40,00,000 | ₹35,00,000 | -₹5,00,000 | Harvest loss |
| ETH | ₹8,00,000 | ₹12,00,000 | +₹4,00,000 | Keep |
| MATIC | ₹2,00,000 | ₹50,000 | -₹1,50,000 | Harvest loss |
Tax calculation after harvesting:
- Realized gains: ₹4,00,000 (ETH)
- Realized losses: ₹6,50,000 (BTC + MATIC)
- Net: -₹2,50,000 loss
- Taxable capital gain: ₹0
- Plus TDS paid: recoverable as credit
Tax saved: ₹80,000 (vs ₹80,000 tax on ₹4,00,000 gain without harvesting)
Important Constraints & Rules
The 30-Day Rule (Soft)
India’s tax authority doesn’t explicitly prohibit repurchasing within 30 days, but selling at a loss and immediately rebuying the same asset may be treated as a “circular transaction” and disallowed. Safe practice: wait 30 days or buy a different cryptocurrency with similar exposure (BTC to BCH, or ETH to MATIC).
TDS Applies Before Loss Consideration
1% TDS applies to every crypto transaction ≥₹50,000. This TDS is credited against your income tax but makes harvesting less effective during high-volatility periods.
Short-Term vs Long-Term Treatment
- STCG (held <12 months): Taxed at slab rate (up to 30% for high earners)
- LTCG (held ≥12 months): Taxed at 20% (less favorable than stocks at 10% with indexation)
For harvesting, prioritize selling short-term losses first to offset short-term gains (same slab rate).
AMT Considerations
If your total income triggers the Alternate Minimum Tax (AMT) at 18.5%, loss harvesting benefits are capped. Check your AMT liability before large harvesting moves.
Common Mistakes to Avoid
-
Selling to realize losses but not reducing portfolio exposure — If you reduce overall crypto holdings, you miss upside. Rebuy the same or similar asset.
-
Harvesting too late — Must sell before March 31 (India’s fiscal year-end). Selling on April 1 counts for the next financial year.
-
Not tracking basis adjustments — Transaction costs increase your basis. A ₹1,00,000 buy with ₹1,000 fees has ₹1,01,000 basis, so your loss is smaller than apparent market decline.
-
Conflating rupee volatility with crypto loss — If your ₹10 lakh BTC position drops to ₹9 lakhs because BTC fell 5% but rupee strengthened, only the 5% BTC drop counts as loss. The rupee gain is separate.
-
Harvesting without a strategy — Randomly selling losers might lock in losses on assets about to recover. Use technical analysis and on-chain metrics to filter candidates.
Indian Investor Checklist
- Track all crypto transactions with date, price, fees (use Koinly or CoinTracker India integrations)
- Identify positions down >15% by February
- Sell and realize losses by March 31
- Document the 30+ day period before reentry
- File ITR-2 Schedule SA with complete crypto transaction details
- Keep exchange receipts and bank statements for 5 years (Tax dept audit period)
- Use loss credits before April 1 (fiscal year end)
Bottom Line
Tax loss harvesting can reduce Indian crypto investors’ effective tax rate from ~20% to ~10% or lower, especially for those in higher income brackets. The strategy is legal, documented in tax precedent, and increasingly used by institutional investors. However, execution requires careful timing, meticulous record-keeping, and awareness of India’s specific TDS and fiscal year rules.
For most Indian retail investors holding ₹10-100 lakh in crypto, implementing tax loss harvesting during down markets (like current), combined with strategic rebalancing, can save ₹1-5 lakh annually in tax.
