Crypto to Crypto Swap Tax Calculator

Each leg: (rupee value received − previous leg's value) × 30%. Losing legs are ERASED, not netted. Taxable = sum of the winning legs.

Section 115BBH charges income arising from the transfer of a virtual digital asset, and an exchange of one crypto asset for another is a transfer of the first asset, so the charge does not wait for a withdrawal to a bank account. The consideration is the fair market value in rupees of the asset received on the date of the exchange, which means a trader who has never converted anything back to rupees can still have made hundreds of taxable disposals across a year. The cost of acquisition of the asset taken on is that same rupee value, so the basis chains through the sequence and each leg is charged only on the increment over the previous one rather than on the whole rise from the original purchase — which is also why the legs have to be walked in order, since computing any single swap in isolation gets the cost wrong for every swap after it. What converts this from an administrative nuisance into a serious exposure is section 115BBH(2)(b), which provides that a loss arising on the transfer of a virtual digital asset shall not be allowed to be set off against income computed under any other provision, cannot meet a gain on another virtual digital asset, and cannot be carried forward to any subsequent year. Applied to a chain of swaps this means every leg that rose is charged at 30% and every leg that fell is simply erased, so the amount brought to tax is the sum of the winning legs. That sum is always at least the real profit on the chain and is usually a great deal more. The clearest illustration is a round trip: a sequence that swaps up, down, up, down and finishes in the coin it started with at the price it started at has made precisely nothing, yet ₹11 lakh of upward legs produces ₹3.43 lakh of tax with the ₹11 lakh of downward legs contributing no relief whatever. The same arithmetic can leave a trader taxed heavily on a chain that lost money outright. The liability is compounded by the fact that swaps produce no rupees. A sale generates the cash with which to pay the tax on it; a swap generates a different coin, so the obligation is denominated in money the transaction never created and must be met by liquidating something or funding it from elsewhere. Selling later at a lower price offers no route out, because that decline is itself a fresh loss under section 115BBH and is extinguished on the same terms. Withholding runs alongside all of this: section 194S deducts 1% of the consideration rather than of any gain, so it applies to losing legs as readily as winning ones, and CBDT Circular 21 of 2022 confirms that in an exchange of one virtual digital asset for another both parties are buyer as well as seller and both are therefore required to deduct, so a single swap carries the deduction twice over. Finally, section 115BBH(2)(a) permits the cost of acquisition and nothing else, so exchange fees, network gas and spread are deductible at no point in the chain — the tax is identical whether the trader paid a great deal in fees or none at all.
