Here's what you should do
The first step is to download all your data from Indodax and import them into Koinly. There are a couple of ways you can do this:
- As Indodax has an API, the most efficient way to import everything is to just add your API keys (API key, API secret). After that, Koinly will download all your transaction data, and you will be ready to create your tax form.
- If you don't have access to your API keys, you can also import transactions by uploading CSV files.
- If the above method(s) is not possible for you, you can also add the transactions manually via Koinly's web interface.
Note that if you want to import CSV files, you must make sure to import your deposits/withdrawals and trades for ALL 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 crypto tax documents!
