Your frequently asked questions
How are BASE transactions taxed?
Wherever you live, chances are your BASE transactions will be taxed. Generally speaking, any gain from selling, trading, or spending crypto is subject to Capital Gains Tax, while any new tokens you earn, through for example staking rewards, may be subject to Income Tax. This said, crypto tax varies depending on where you live, so make sure to learn about the crypto tax rules in your country.
How do I get a BASE tax report?
The easiest way to get a BASE tax report is to use a crypto tax calculator like Koinly. All you need to do with Koinly is connect automatically using your public address and Koinly will import your transaction history, identify taxable transactions, and calculate your gains, losses, and income. After it has done this, Koinly generates a crypto tax report, ready to help you file.

This very much depends on the crypto wallet you're using. Some wallets may allow you to export a CSV file of your transaction history for accounting and tax purposes, while others may not. But you can always use a crypto tax calculator like Koinly to export your BASE transaction history automatically and easily using your public address.
