WISO Steuer 2021
WISO Steuer 2021 is a German tax preparation and filing software from Buhl Data. It guides users through the process of preparing their annual tax return (Steuererklärung) for submission to the German tax authority (Finanzamt), handling income tax, business income, deductions, and other tax-related forms specific to the German tax system. The app is updated annually with new tax forms and rules for each year, and the "2021" designation indicates this is the version for the 2021 tax year. It is primarily used by self-employed individuals, freelancers, and employees in Germany who want to prepare their returns independently rather than hiring an accountant.

1 suggestionWe could not locate recent information about WISO Steuer 2021's Apple Silicon support status. This app was designed for a specific tax year (2021), and tax software is typically retired and replaced annually — meaning WISO Steuer 2021 may no longer be actively supported or maintained by Buhl Data as of 2026. Even if it still runs under Rosetta 2 today, it will stop working entirely when Apple removes Rosetta in macOS 28 (September 2028). If you still rely on this version, contact Buhl Data directly to ask whether a native Apple Silicon build was ever released, and whether the current year's edition of WISO Steuer (likely WISO Steuer 2026 or 2027) ships with native support. If Buhl Data has discontinued this older tax year's version, you will need to purchase and update to the current year's edition — tax software is a workflow that typically advances with the calendar year, so this may be expected regardless of the Apple Silicon situation. Check the official Buhl website (buhl.de) or your WISO account to confirm which version is current and what architecture support it offers.
