AI tax software in Europe and the UK

Country-by-country consumer apps rather than one continental market — plus the world's densest cluster of VAT automation.

Europe has no single tax market, so its consumer champions are national: Taxfix in Germany, Spain and Italy; TaxDown in Spain; Indy in France; Fiscozen for Italian partita IVA holders; WISO Steuer for German power users. Consolidation is underway — Taxfix acquired Steuerbot in 2023 and TaxScouts in 2024, and has processed over 5 million returns.

The UK is distinct again, shaped by Self Assessment and Making Tax Digital: TaxScouts pairs software intake with accredited accountants, while Pie and Coconut keep a live tax estimate against HMRC categories. On the business side, VAT drives the continent's indirect-tax cluster — Fonoa in Dublin, Blue dot's VAT recovery, and the VAT coverage inside Anrok and Sphere.

Frequently asked

Is there AI tax software for German tax returns?: Yes. Taxfix and Steuerbot both file German income tax returns through a chat-style interview, and WISO Steuer — the long-standing market leader — added a SteuerGPT assistant alongside receipt scanning and bank import.
Can AI file a UK Self Assessment return?: Pie and Coconut are HMRC-recognised and maintain a live Self Assessment estimate from connected accounts. TaxScouts takes the hybrid route, using software for intake and an accredited accountant to complete and file, usually within about 48 hours.
