This is how Germany's most popular mobile tax app was created

Taxfix is based on the simple idea that doing taxes should be easier, and that everyone should be able to take their finances into their own hands.

Taxfix: The intuitive solution to a well-known problem

Most people are afraid of doing their own tax return. They’re afraid of making mistakes or even getting into trouble with the tax office. But, in fact, 9 out of 10 people get a refund when they file their tax return.

We’re here to help taxpayers reclaim the money they’ve worked hard for – especially those who need it most.

That's why we offer an intuitive solution with our tax app that helps everyone get the best possible refund. With an included error check and built-in data check, your tax return will always be complete, accurate, and submitted fast. On average, you can complete your tax return in less than 30 minutes – regardless of whether you have any tax knowledge or not.

With Taxfix, you can file your tax return quickly and paperlessly from anywhere, via app or browser. Provide information on your tax situation according to the question-and-answer process to have your possible refund calculated. When you’re ready to submit, we forward your data to the tax office via the official ELSTER interface.

The vision of simplicity

After many years of friendship and numerous joint projects, Mathis Büchi and Lino Teuteberg joined forces to find a solution to the unpleasant topic of taxes. The goal: make life easier for taxpayers.


An incredible journey begins

The two founders quickly built a team of international tax experts, engineers, data scientists, copywriters, designers and other creatives. Together, Taxfix is dedicated to the vision of developing a product that makes it easy for everyone to save on taxes and time. Paperless. Easy to understand. Efficient.


Smart taxes for the whole world

Thanks in part to the last major financing round in 2020, Taxfix has grown many times over in recent years and is now not only available in Germany, but in Spain and in Italy too. Taxfix helps millions of people submit their tax returns online.


New ideas and proven knowledge

In September 2021, Martin Ott was introduced as the new CEO. Mathis Büchi, founder and previous CEO, was to support the company as Chairman of the Board. His co-founder and Managing Director, Lino Teuteberg, continued his responsibilities towards product development. With the management team reinforced by Martin Ott, the signs for this FinTech company continue to point to full growth.

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.

Have your taxes done for you: With Expert Service, simply upload a few documents and receive your tax return in a matter of days. All you have to do is check and approve it.

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. Alternatively, you can use Taxfix Expert Service and have your tax return done for you by an independent tax advisor. 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.
