Tax applications and advisory for Interactive Brokers users

Tax applications and advisory for non-US Interactive Brokers users

Application for calculating inputs for tax returns, including related tax consulting.

Active traders and investors have to file a tax return statement in the country of their residence. Therefore, we have prepared a tax app, including the related advisory, to provide all the necessary documents for taxing profits from investments.

Currently, our tax application can generate reports for any natural person and any entrepreneur whose main business activity is not trading. In the MVP version, the application takes into account the trading of stocks by users from the Czech Republic using the Interactive Brokers (IBKR) broker. We have been working on harmonizing our app with the other countries‘ tax laws and other types of users and brokers.

Tax advisory

For our Premium Plan clients, the services of an external tax advisor are included.
Therefore, you only need to download all three mentioned reports from the “Reports” section
in your IBKR account and send them to the tax advisor.

The tax advisor will afterward fill the whole Appendix No. 2 of the tax return according to the trades executed as suggested by our tools.


If you are trading other financial instruments or using different platforms to trade, you should file a tax return for each. Unfortunately, the tax advisory service in the Premium plan does not include assistance with your other accounts or merging the information into one summary document. However, we can provide these services as a separate service.

Please be aware that we only provide the software. We always recommend asking a specialized tax advisor for help.
