Steuer-Sparer

What Steuer-Sparer is

Steuer-Sparer is paid Windows software from Buhl Data Service GmbH in Neunkirchen (Siegerland), Germany, for individual income tax returns. You download and install it with a personal installation code, so the program CD is not needed. The software supports electronic filing through ELSTER. Its FAQ explains that filing requires a digital signature; submission without one has not been available since tax year 2021. A Buhl account is required, and each start includes a license check using a guarantee number and the Buhl account. Users can request tax data directly from their tax office when they give express consent and receive an activation code by mail. Sending a return requires a one-time identity check, with a bank account, ID verification, POSTIDENT, and Verimi listed as possible methods. Buhl says it does not sell, rent, or lend personal data, uses technical and organizational safeguards, and does not share tax data without consent, including transmission through ELSTER. The maker’s installation guidance covers Steuer-Sparer 2026 on Windows 10 and Windows 11. The product supports amended returns.

Limits
