In some sense these threads here are similar to this topic: Export Transaction List with more Information, More detailed statements
I fixed the thread title to differentiate this a bit from those existing threads.
But that one is primarily for personal account and as far as I understood is requesting details which would be a quality of life improvement, on some sense my thread is similarly quite a quality of life improvement, but primarily to ease the hassle of doing a tax report. I honestly would like to see both happening, but legal responsibilities before quality of life. Probably both ones should happen to cover GDPR requirement of having exportable personal data in a complete form.
