WISO steuer: 2019

WISO steuer: 2019 is a year-specific tax software edition for the 2019 tax year in Germany, and the bundle ID indicates this is the 2019 release. Tax software is inherently tied to the tax year it covers — once a new tax year arrives, the previous year's edition becomes obsolete for filing purposes. As of May 2026, this app is approximately seven years out of date for tax filing and would not be usable for current German tax returns. Beyond obsolescence, there is no available information about whether a native Apple Silicon build was ever released for this edition, and it is unlikely given the age of the software. The app will stop running entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). If you need to prepare German tax returns for recent years, you should obtain the current year's edition of WISO steuer from Buhl Data — they typically release new versions annually and those current builds may include native Apple Silicon support. If you are archiving or reviewing historical 2019 tax records, you can continue using this Intel-only app under Rosetta 2 until September 2028, but you cannot file a 2019 return with it in 2026 anyway since that deadline has long passed.
