To use the Expert Service, we are legally required to verify your identity. This ensures your tax return can be securely and lawfully prepared on behalf of our partner tax firm.
📌 Quick & Easy
- Without successful identification, your tax return cannot be prepared by the expert.
- Common reasons for rejection: expired, unreadable, or incomplete documents – or mismatched details in the app.
- You can resubmit your documents at any time or contact us directly if your details differ.
🚀 Your Guide
- Why was my identification declined?
- What should I do now?
- Which documents are accepted?
- What if my name is different?
- What if this involves an inheritance?
Why was my identification declined?
The identity check may fail for several reasons:
- Your ID is expired.
- The document is blurry, pixelated, or not fully visible.
- The wrong type of document was uploaded.
- The name or address on your ID doesn’t match the information in the app.
💡 Please review these points and upload your documents again – either directly in the app or by replying to our email.
What should I do now?
Please send your valid ID documents as soon as possible to: support@taxfix.de.
Only after successful identification can our partner tax firm begin preparing your tax return.
⚠️ Note: Missing or invalid documents will pause your Expert Service process.
Which documents are accepted?
✅ National ID card
✅ Residence permit
✅ Passport
✅ Driver’s license
💡 If your name has changed (e.g. due to marriage), please also send a supporting document such as a marriage certificate by email.
📸 Important:
- Your full name must be clearly visible.
- The document must be high-quality and fully shown.
-
No scans or screenshots – only clear original photos are accepted.
What if my name is different?
If the name on your document doesn’t match the one in the app, we cannot proceed.
👤 Example:
Name on document: Max Müller
Name in app: Max Mustermann
In this case, you have two options:
- You want to update the name in the app? ➤ Let us know via email – we’ll update it for you.
- The name in the app is correct? ➤ Then please send a new ID document showing the correct name.
👉 Accepted proofs:
- One of the ID documents listed above
-
Official proof of name change (e.g. marriage certificate)
What if this involves an inheritance?
In special cases – such as the death of a relative – a tax return can only be prepared through the Expert Service if a certificate of inheritance is provided.
🧾 This document proves you are legally entitled to receive the tax refund. Without it, we cannot issue any payments due to legal restrictions.
If no certificate can be provided, the process will be canceled. If you have already paid, we will refund the service fee.
📩 Please email us to let us know how you’d like to proceed.
