About Taxfix




Taxfix: A simple solution for a common problem

Taxfix is focused on helping you file an error-free tax return. We analyse your situation in detail to find all applicable deductions to offer you the best possible refund. We collaborate with the Tax Agency, so we can file your tax return automatically. Easy and hassle-free.


Our mission is simple: We help people successfully claim their money.


A vision is set: simplicity

In 2016, after years of friendship and numerous joint projects, Mathis Büchi and Lino Teuteberg decided to find a solution for a widely dreaded topic: taxes. Their goal was to ease the lives of taxpayers.


An incredible journey begins

The founders got off to a good start. They gathered a team of international tax experts, engineers, data scientists, texters, designers, and other creative professionals. At Taxfix, we work hard to develop a product that saves time and effort for anyone who wishes to file their return online, easy and error-free.


The smart way to file taxes

The last major funding in 2020 built the foundation for a solid growth. Taxfix is now also running in France and Italy and continues to help millions to file their taxes online.


We keep growing

In September 2021, Martin Ott became the new CEO. Mathis Büchi, founder and former CEO, continues as Chairman of the Board. Lino Teuteber, co- founder and former CPO is responsible for product development at Taxfix. With Martin Ott at the head of the company, all signs point to rapid growth as a FinTech company.


Taxfix lands in Spain

True to its initial objective, Taxfix remains focused on helping taxpayers understand and manage their own finances. Just like in Italy and France, bureaucracy and paperwork is a procedure that we tend to avoid in Spain. The German app has arrived so that April 6th is associated with a new beginning for everyone.
