Yes, this is a common issue: the electronic DA-1 form in Zurich has a limited number of rows for securities transactions by default. But there are a few solutions:
Solution 1: Attach additional sheets
If you have too many transactions, you can upload or print the securities statement from your IBKR account (e.g., annual tax report or dividend report) as a separate file. You can indicate in the form that the detailed list is attached separately.
Solution 2: Use an Excel template from the tax authority
Some cantons provide an official Excel template where you can enter all transactions and submit it as an attachment. Check if Zurich offers such a template. If not, you can create your own Excel list.
Solution 3: Manually expand the DA-1 form
If you want to edit the form directly, you can try opening the PDF version with Adobe Acrobat or a PDF editor and adding more rows. However, in some cases, this might cause issues when submitting it digitally.
