Here's what you should do
The first step is to download all your data from itBit and import them to Koinly. There are a couple of ways you can do this:
- As itBit has an API, the most efficient way to do so is to simply add your read-only API keys (API key, API secret). After that, Koinly will sync your transactions, and you will be ready to generate a tax document.
- If you don't have access to your API keys, you can also import transactions by uploading your CSV files.
- If the above method(s) is not possible for you, you can also add the transactions one by one via Koinly's web interface.
Note that if you want to import CSV files, you need to make sure to import your deposits/withdrawals and trades for ALL previous years - not just the current one!
That's all you have to do. Don't forget to tag your airdrops/forks so they show up as Income on your final cryptocurrency tax reports!
