Taxfix vs WISO Business

Taxfix provides digital tax returns that users can prepare themselves or have prepared by independent tax advisers. In Basic, a question-led process guides users through a return and provides an initial refund estimate. The Start plan offers a free estimated refund calculation, with submission through Basic. Taxfix sends returns to the tax office through the official ELSTER interface. Basic works in a browser and through Android and iOS apps. For Expert, users answer questions and upload documents; an adviser reviews and prepares the return for the user to confirm. The listed Expert fee is 20% of the refund, with a minimum of €99.99, and may apply even if the return is not submitted. A separate solution for VAT-liable self-employed people combines bookkeeping, receipt capture, VAT pre-returns, and income tax returns including EÜR. Uploaded receipts and invoices are read for details such as amount, date, and tax rate. Taxfix says it uses encryption, does not share data with third parties, and operates servers mainly in Germany or elsewhere in the EU while observing GoBD and GDPR. Basic is free until submission; individual annual filing costs €39.99 a year, and one-time filing costs €49.99, paid once payment.

WISO Business is cloud-based software for invoices, payments, and handling income and expenses for tax returns. Its Gratis starten plan is permanently free and includes unlimited classic and electronic invoices, receipt scanning with a digital archive, online payments in invoices, and a real-time business overview. Paid plans add the listed tax functions: transferring income and expenses into a tax return, online tax submission, and a pre-check. Upgrade für WISO Steuer-Nutzer costs €63 per year, while Komplettpaket: WISO Business + WISO Steuer costs €99 per year. Both paid plans include the free plan features and the same stated tax functions. Reconciliation automation and an audit trail are also listed. WISO Business is available on Android, iOS, and the web. The choice between the two paid plans therefore comes with different annual prices, while their described included features match.
