Company Intro & Mission


As one of the most successful and fast-growing FinTech startup companies in Europe, we are currently experiencing exciting growth and development. We are revolutionising the way people file their taxes; helping them to save money, time and stress by putting a personalised digital tax consultant into the palm of their hands. Our user-friendly Taxfix App enables people to file their tax declaration within 22 minutes on average, without any prior tax knowledge or the complicated forms associated with it.

Our offices in Berlin and Madrid are home to a diverse team of 200+ people who come from more than 40 nations around the world!


Our Tech Environment


The tax industry is outdated and we have embraced the disruption we can cause here by innovating and thinking outside of the typical "Tax box". We have created our own modelling language - TaxML so our tax experts can focus on designing user journey, while developers can focus on improving the product.

Our Tech stack is React and React Native on the frontend, NodeJs and Elixir on the backend. Everything is running in Docker, orchestrated by Kubernetes and powered by Google Cloud Platform. We are big fans of decentralised end-to-end ownership, cross-system contracts, internal open-source and data-driven decisions.

Our cross-functional teams have full exposure to all of the tech, and we support your development with the areas you want to grow. We have introduced internal Tech communities where you can join the one that excites you the most! We hire for your values and drive to learn - not just your technical skills, we love to foster growth from within.

We love to welcome the Berlin Tech community to our home here at Taxfix for Meetups and events.
