Points
Based on published terms and features
Zasta follows a unique business model: the tax return is not only prepared by software but also checked by a genuine tax adviser. If the refund is under €100, the whole service is free – so the risk lies with the provider.
Highlights of our Zasta review
- Zasta scores 64/100 points.
- A genuine tax adviser checks every return.
- Free if the refund is under €100.
- Objection service included.
Table of contents
1 Range of functions
19/35
Points
Zasta supports income tax. Receipt scan via app and ELSTER submission (the tax authorities' online filing system) via the tax adviser. Objection service included. No optimisation of its own – the tax adviser takes over.
Scoring (19/35): Solid basic functions. The tax adviser check is unique. But document retrieval is missing and there are no AI tips.
2 Usability
14/21
Points
Interview mode available. The app is kept simple. Carry-over from the previous year possible. The workflow is different: you prepare the return, then an adviser checks it – that takes longer.
Scoring (14/21): Simple to use, but the adviser check delays the process.
3 Price & licence
8/21
Points
Free if the refund is under €100. Otherwise a fixed price of €99. Considerably more expensive than pure software solutions, but with a tax adviser check.
Scoring (8/21): The risk-free model is interesting, but €99 for higher refunds is expensive by comparison.
4 Platforms
9/12
Points
Web and app (iOS/Android). Cloud-based.
Scoring (9/12): Web and app with cloud sync. No desktop.
5 Support & security
8/11
Points
In principle the tax adviser is the support. Email support in addition. Hosting in Germany.
Scoring (8/11): A tax adviser as a support channel is a plus. German hosting.
