Overview

The service gives filers several ways to assemble a return: photograph wage statements and receipts for automatic recognition and entry, or authorize retrieval of tax data such as wage-tax information from the tax administration. The expected refund updates as information is entered, and completed returns are transmitted to the tax office through the official ELSTER interface. Together, these tools reduce some manual work while keeping the likely result in view.

One license covers up to five returns, which can suit a household or someone filing for several people. WISO Steuer supports income tax returns only for people with unlimited tax liability in Germany. That restriction is decisive: it is not the right choice for filers outside that group.

Key features

Document entry and tax-data retrieval

Photographing wage statements and receipts lets the software recognize and enter information instead of requiring every figure to be typed. With consent, it can also retrieve tax data from the tax administration. These options are most useful to filers with documents and records that can be brought in this way; they do not remove the need to prepare a return.

Live estimate and filing

The refund estimate changes as users enter information, giving them a running view of the expected outcome. Electronic transmission uses the official ELSTER interface, so filing is part of the product rather than a separate manual submission step.

AI, banking and data handling

SteuerGPT answers tax questions in natural language within the program. Tax Banking can retrieve and categorize transactions, but requires a finanzblick account. Buhl says data is stored on its servers in Germany and protected in transmission and storage with HTTPS and AES-256 encryption. The privacy notice says personal data is not generally shared, subject to exceptions such as service providers, legal requirements or user consent. For SteuerGPT, it names Taxy.io GmbH as processor and Microsoft Azure servers in Germany.

The Vorteils-Abo includes a technical support hotline, and users can also submit support requests through Buhl’s ticket system.

Pricing

Testversion — free

All functions can be tried without charge, but payment is requested when submitting the tax return. This is a useful way to prepare and assess the workflow before committing; it is not a free filing option.

Vorteils-Abo — 35.99 EUR per year

The annual subscription covers five tax returns and includes the technical support hotline. It renews automatically each November, so subscribers should account for that renewal when deciding whether to keep it. The five-return allowance makes it the better fit for households or multiple filings than a one-return purchase.

Einzelkauf — 45.99 EUR per month

This is a one-time purchase for a tax year, with one-time submission for that year and SteuerGPT as a personal AI adviser. It suits someone who wants a single tax-year purchase rather than an automatically renewing subscription, but its one-return submission limit is less generous than the subscription’s five returns.

Platforms

WISO Steuer runs on Android, iOS, Linux, macOS, the web and Windows. The range covers phones, desktop systems and browser access, so users are not restricted to one device type.

Who it's for

The product is intended for employees, self-employed people, retirees, landlords, families and beginners. It also supports self-employed and rental income, making it relevant beyond straightforward wage-only filing. In every case, the user must have unlimited tax liability in Germany.

Pros and cons

Pros: Photo-based document recognition and consent-based tax-data retrieval can reduce manual entry.

Verdict

Choose WISO Steuer if you have unlimited tax liability in Germany and want guided preparation, several ways to bring in tax information, a live estimate and electronic filing in one product. The five-return annual subscription is particularly suited to households and multiple filings. Look elsewhere if you fall outside its eligibility rules, need a genuinely free submission, or do not want an automatically renewing subscription.
