I am selling a coin on Binance Smart Chain (which I have linked as a synchronising wallet). If I sell, say, 100 coins, I have to pay a “sales tax”, determined by the coin’s smart contract. Koinly determines that I have received the value of 88 coins for the 100 coins sold, which is correct.
How should I record (with a manual transaction) the 12 coin sales tax? If I create a Withdrawal with the category of Cost, Koinly recognised a capital gain on those 12 coins. This doesn’t seem right as I am seeing the same gain as I would have seen had I benefited from the sale of all 100 coins.
It seems to me my only capital gain is from the 88 coins whose value I received. How can I record that my balance has reduced by 88 + 12 without incurring a capital gain on the 12?
Thanks,
Julian
