Filing your German tax return: How wundertax makes it simple
Filing taxes in Germany can feel overwhelming, especially for expats. Germany’s tax system is known for being thorough and paperwork-heavy. Between unfamiliar rules, official forms written in bureaucratic German and the constant fear of making mistakes, many expats delay or avoid their German tax return altogether, risking late fees or missing out on a substantial tax refund.
That’s exactly where wundertax steps in. Designed with expats in mind, the platform helps you file your German taxes simply, securely and confidently, fully in English, digitally from start to finish, and without any stress.
100% in English: From filling out to customer support
At the heart of the platform is a 100% English-language tax questionnaire that guides you step by step through your tax return. No prior knowledge of German taxes is required: you simply answer clear questions in English.
The tax questionnaire adapts to your personal situation, whether you’re employed, self-employed, married, or earning income from different sources. Behind the scenes, wundertax automatically generates the correct forms for the German tax authorities.
You’ll also find tips and explanations throughout the process, so you always understand what’s being asked and why it matters. And if questions still come up, wundertax offers excellent English-speaking customer support, a huge relief in Germany’s otherwise German-only tax landscape.
