WISO steuer: 2020
WISO steuer: 2020 is a German tax preparation and filing software from Buhl Data. It guides users through the income tax declaration process, handles deduction calculations, supports various income types (employment, self-employment, investments), automates data transfer from financial institutions, and generates the official forms needed for submission to German tax authorities. The app is part of the WISO steuer product family, which is the market-leading tax software in Germany and Austria.
AI Recommendation
1 suggestionWISO steuer: 2020 is a yearly product release tied to the 2020 German tax year, now several years outdated. Current tax filers should upgrade to the latest tax year edition (WISO steuer: 2025 or later) to ensure compatibility with current tax law, deduction rules, and official filing requirements. The 2020 edition is unlikely to receive updates or native Apple Silicon support. Contact Buhl Data directly to confirm whether a current-year native build is available, or check their official website for the latest WISO steuer release suitable for your current tax year. If you are archiving old tax records or do not need to file current taxes, the existing Intel build continues to run under Rosetta 2 today but will not launch on macOS 28 (September 2028).
