About Zasta
Zasta occupies a distinct lane in German tax tech: instead of DIY software, it estimates your expected refund in about three minutes, then matches you with one of its partnered certified tax advisors (Steuerberater), who prepares and files the return professionally.
The model appeals to filers who want a professional's signature rather than software self-service — automation handles intake, estimation, and matching.
Automated intake instantly estimates the expected German refund and matches each user to a certified tax advisor, who reviews and files the return.
Highlights
- Positions itself as Germany's leading platform for matching taxpayers to certified tax advisors
- Free upfront refund estimate in ~3 minutes
- Available as the Zasta "Super-App für Steuern" on iOS and Android
