Sample report: a finished German tax report for Interactive Brokers

This is what a finished tax report looks like.

Before you upload your own data, you can look at a complete report here. It comes from an anonymised test account at Interactive Brokers with 726 transactions in tax year 2024: shares, funds, dividends from several countries, interest and an interest-bearing US dollar account.

The report consists of two PDF files. The summary contains the amounts per form line and the derivation by category. The detailed report adds the appendix with every single sale, its FIFO allocation and the broker's original bookings.

Direct download, no form, no account. Anonymised test case (account ID U9999901), no real personal data.
