From your My Transactions page, you'll see a full list of all of the transactions in your TaxBit account, which are each categorized into a specific "Type". This article will briefly explain each type, and why it's important to understand what distinguishes each type from one another.
Purchase of crypto with fiat (i.e; Paid $5,000 for 1 BTC)
Sale of crypto for fiat (i.e; Sold 1 BTC for $5,000)
Trading one crypto for another crypto (i.e; Trade 1 BTC for 10 ETH)
Transfer crypto to an exchange or wallet in your possession (i.e; Moved 1 BTC from Coinbase to a hardware wallet)
Received crypto in return for goods or services (i.e; Received 1 BTC in return for mining)
Sent crypto in return for goods or services (i.e; Sent 1 BTC as payment for a car)
Being able to identify how the different transaction types are represented within your account, as well as how to filter them, will help you make sense of the data as you're reviewing your account:
If you're syncing all of your data in via API integrations, then you can rest assure that everything in your account is represented properly. However, if you're importing any data via CSV, or creating transactions manually, then it's critical to understand how each of these transaction types will impact your tax calculations, and what transactions you actually need to have in your account.
At a high level, any transaction which records you acquiring an asset for the first time (Buys, Income and Trades) sets cost basis. When you eventually dispose of that asset (Sales, Expenses and Trades), we'll use that first transaction to know how much in gain or loss you realized.
