For taxpayers
Your documents, ready for your firm
crosstax guides you step by step through exactly what your tax firm needs — you upload documents, your firm handles the rest.
Guided input
Clear questions instead of blank forms. You only answer what's relevant to your case.
Documents read automatically
Upload a photo or PDF — crosstax detects the values and suggests them, transparently and verifiably.

German, English, French, Italian or Spanish — you fill it in, your firm receives everything in German.
