WISO Steuer is a German tax preparation software available for desktop, web and mobile platforms.
History
[edit]The software was first released in 1991 under the name WISO Steuer-Sparbuch. It was marketed in connection with the German ZDF business television programme WISO. In 1999 Buhl released the web application WISO Internet-Sparbuch enabling users to submit tax returns online. In 2023 Buhl renamed WISO Steuer-Sparbuch to WISO Steuer.[1]
Features
[edit]WISO Steuer handles the preparation and electronic submission of German tax returns through the official ELSTER interface. It's supports employee cases, investment income, self-employed, international tax cases, and freelancers, including EÜR accounting.[2][3]
The software can import wage-tax certificates, pension data and insurance data. It can also retrieve tax assessment notices (Steuerbescheide) and compare them with the submitted tax return.[4]
Other functions include receipt scanning, plausibility checks and bank-account data import. WISO Steuer has recently developed SteuerGPT, an AI-based chatbot for tax questions.[5]
Publisher
[edit]WISO Steuer is published by Buhl Data Service, a privately held, family-owned software company headquartered in Neunkirchen. The company reported revenue of €185.4 million for 2024.[6]
Reception
[edit]Computer Bild has described it as a comprehensive software for both simple and more complex tax situations in its 2026 review.[7]
Finanztip has selected WISO Steuer as its overall recommendation in its last comparison.[8]
