There are two ways to file your tax return with Taxfix: complete the simple question-and-answer process via app or browser, or have your taxes done by an independent tax advisor using Expert Service.

If you do your tax return yourself, you can get a free calculation of your estimated refund before submitting to your local tax office via the official ELSTER interface.

Do your own taxes: After registering through the app or browser, you will answer an average of 70 questions, specifically tailored to your tax case. You will then immediately receive a free calculation of your estimated refund. If you choose to submit your taxes at that point, we will submit your tax return to your local tax office. Once the tax office has processed your return, your potential refund will be paid into your account and you will receive your tax assessment.

Download the Taxfix app for free from the Apple App Store, the Google Play Store, or access our site in your web browser. At no extra cost, you can calculate your expected tax refund. Find the current prices for both services on the Taxfix costs page.

Submitting a tax return is definitely not something you do off the cuff. And when specialized knowledge is required, it’s understandable to be cautious or even feel sceptical.

For questions that require explanation, Taxfix offers info texts and corresponding advice articles or tax tips. These resources will help with general tax questions on specific points, but not with individual tax questions.
