If anyone is actually using this spreadsheet: just found an error today. I count the wealth tax twice.
To fix: delete row 23 (“Vermögenssteuern”) on sheet “Einkommen/Ausgaben”) in your copy – this tax is already accounted for in row 20.
I’ve deleted the row on the linked Sheet so anyone newly making a copy should profit from it and I’ve provided a visual reference for those who made an earlier copy and don’t easily see what they should update from my how-to-fix instructions.
