Does DAC8 mean my taxes will be automatically withheld?
No. DAC8 only regulates the reporting of tax-relevant data. Your taxes will not be automatically deducted. The responsibility for paying taxes on your cryptocurrencies remains with you as the user. Further information can be found in frequently asked questions about DAC8. For specific questions about taxes, please consult a tax or legal advisor.
Where can I find an overview of all my transactions at BISON?
A complete overview of all your transactions can be found in the BISON Info Report. You can access the report at any time under "Account" → "Reports" → "Crypto Info Report".
The BISON Info Report clearly and transparently records all transactions. You can see at any time which of your data BISON processes and transmits under DAC8.
The Info Report also helps you keep your own records – for example for your tax return – complete and correct.
Please note, however, that this Info Report is not legally binding. The final review and reporting in your tax return remains your responsibility. For specific questions about your taxes, please consult a tax advisor or legal advisor.
