1 Range of functions

22/35
Points
Taxfix covers income tax well, but is not suitable for trade tax, VAT or complex rental cases. Automatic document retrieval with pre-filling works reliably. AI-assisted tips help find deduction opportunities. ELSTER integration (the tax authorities' online filing system) allows direct submission. Scoring (22/35): Good range of functions for employees, but limited for trade/VAT. Document retrieval and ELSTER submission work flawlessly.

2 Usability

19/21
Points
Taxfix's interview mode is outstanding – it is the most intuitive on the market. Simple questions in natural language, visual aids and progressive disclosure. The help pages are good, but explainer videos are missing. Carry-over from the previous year is possible automatically. Scoring (19/21): The best usability in the comparison. Interview mode is the reference. Only a minimal deduction for missing explainer videos.
