Our take
For many people, filing taxes is still a painstaking, confusing and outdated process. In Germany alone, around 10 million people each year decide not to claim their tax return for this reason. Taxfix solves this problem by making it easier to file tax returns and claim rebates.
Taxfix serves as a personal tax accountant, something that many of its users can't afford or don't have access to. The app functions much like any chatbot, offering in-depth guidance and optimising the tax filing process. Users can typically file their taxes in under 20 minutes using the app, which will appeal to anyone looking to save time and effort on their personal finances. Taxfix is not alone in offering this sort of service, but it sets itself apart from rivals such as TurboTax thanks to its mobile-first approach.
The company has been well-served by its innovative and attractive app interface and acquired its German competitor Steuerbot in early 2023. With its European market covered by Berlin and Madrid offices, 2024 saw its entrance into the UK market by acquiring smaller competitor Taxscouts, establishing itself as the European leader in its sector.
