What is the pre-filled tax return?

The prefilled tax return (VaSt) is a voluntary and free service provided by Taxfix. It allows you to retrieve certain data – such as wage, insurance, or pension information – that has been reported by employers, insurers, or pension providers to the tax authorities and is already on file there. With your consent, this data can be automatically imported into your tax return within the Taxfix app.

👉 You don’t have to use this service – even if you’ve already requested it.

How does the activation code work?

After you’ve submitted your request, you’ll receive an activation code by mail from the tax office. You can enter this code in the Taxfix app within 90 days to activate the pre-filled data.

What happens if I don’t use the code?

If you don’t enter the activation code in the app, nothing happens. The code expires automatically after 90 days, and the request remains inactive. You can still complete and submit your tax return manually as usual.
