The Gain or Loss in any transaction equals the difference between the value of a coin at the time it was purchased minus the value when you sold or traded the coin. If you buy and sell many coins over time, this can get complicated.
How ZenLedger determines the cost basis of a transaction:
ZenLedger takes the mystery of cost basis away by stitching together your complete trading history based on the cost basis accounting method you select (more information on cost basis methods below).
In order to correctly arrive at your net capital gain or loss, capital gains and losses are classified as long-term or short-term. Generally, if you hold the asset for more than one year before you dispose of it, your capital gain or loss is long-term. If you hold it for one year or less, your capital gain or loss is short-term. Check out this article for more information on capital gains tax and how the IRS taxes crypto.
For any cryptocurrency being taxed, ZenLedger finds the appropriate incoming transaction and then finds its fair market price in US dollars at the time it was bought . It then uses that as the cost basis for the taxable transaction. ZenLedger calculates the fair market value (FMV) at any given timestamp for any given cryptocurrency using market data from various price aggregators like CoinMarketCap and CoinGecko. We integrate directly with them and other third-party APIs that specialize in calculating the fair market value for different cryptocurrencies.
