Frequently Asked Base Questions

Do I have to pay tax on Base?

Yes. Crypto and Base activity is generally taxed on gains, losses, and income, although the specific rules depend on your tax residence, the tax year, and your individual circumstances. Buying, selling, swapping, receiving rewards, or transferring cryptocurrencies can all be relevant to your tax return. For more detail, see our crypto tax guides.

Can Blockpit include Base in my tax report?

Blockpit supports the Base data and transaction types listed above. Once imported and reviewed, this data can be included alongside your other exchanges, wallets, and assets in your Blockpit tax report.

What information should I keep for my tax return?

Keep a complete record of your crypto activity, including transaction dates, assets, amounts, values, costs, fees, and transfers between platforms or wallets. A complete portfolio view makes it easier to review your transactions and document your tax position.

Are crypto tax reporting rules changing?

Yes. Tax authorities may already obtain information about crypto activity through data requests and international information-sharing arrangements. In the EU, DAC8 makes crypto tax reporting more systematic: relevant crypto service providers began collecting reportable data in 2026, with the first exchanges of that data expected in 2027. This might include your Base data.

If you have taxable crypto activity, now is the time to make sure your transaction history is complete and your tax return is accurate.
