The story

Taxfix began in 2016 as a Germany-focused mobile-first consumer tax filing app, addressing the 10M+ German employees who skip filing due to complexity. Reached unicorn valuation in 2022 with a $220M Series D and expanded across Germany, Spain, and Italy. In the UK, Taxfix operates via its acquisition of TaxScouts (Positron Technologies Ltd), extending its footprint into self-employed, landlord, and company tax segments — evolving from a pure B2C annual tax app toward a year-round SMB/self-employed financial workflow platform with bookkeeping, bank-linking, and accountant matchmaking.
