To use the pre-filled tax return in the Taxfix app, you need an activation code. Here’s when and how you will receive it.
- Receiving the activation code: The code arrives by mail within 1–2 weeks after you submit your consent.
- Centralized delivery: The code is not sent by your tax office but by an ELSTER central authority and is valid for 90 days.
- Joint filing: Spouses each receive their own activation code in separate letters.

When will the activation code arrive?
Once you request the pre-filled tax return in the Taxfix app, we send your approval to the tax authorities. After that, you will receive your personal activation code by mail.
💡 Tip: If you haven’t received it after 14 days, there could be several reasons. Learn more here.
How is the activation code sent?
📩 By mail directly to your home.
📍 From a central authority (not necessarily your local tax office).
📄 The letter bears the ELSTER logo and confirms your authorization to retrieve tax data.
🔎 Important: Your 12-digit code is on the last page of the letter and is valid for 90 days.
Activation code for joint filing
For a joint tax return, each partner receives their own activation code – meaning you’ll get two separate letters.
Find out how to enter your activation code in the Taxfix app in this article: Entering the activation code and starting your tax return.
ELSTER Users: Can I use the pre-filled tax return with Taxfix?
Unfortunately, no. ELSTER users cannot currently link the pre-filled tax return (VaSt) with Taxfix.
Alternative: You can manually enter your tax data in the app and still complete your tax return without issues. We are working on supporting ELSTER in the future!
