Frequently Asked Questions

After registering with the Taxfix app—through your smartphone or web browser—you will find 70 personalised questions. Not only are the questions simple, but they are also relevant for calculating your tax return. On answering them, you’ll receive your calculated tax refund on the spot. Our tax experts will prepare your tax documents and transmit your tax return to the responsible tax office in an encrypted form if you are satisfied. The tax office will transfer your tax refund directly to your bank account.
With our Taxfix app, you can complete your tax return in about 22 minutes. Once you answer a few easy questions, we’ll do the rest.
You only pay from a tax refund of 50 euros and with compulsory charges. Then the use of our tax app costs 39.99 euros. Use is free of charge for voluntary tax returns where the reimbursement is less than 50 euros.
Taxfix transmits your encrypted tax return reliably through the official ELSTER interface. We do not need any forms or printouts for this. We place the utmost importance on data privacy.
It takes between six to twelve weeks for your tax office to process your tax return. You receive your tax assessment by post. The tax refund will then be automatically credited to your bank account by the tax office.
The most important document is your income tax statement (Lohnsteuerbescheinigung). Since 2017, you don’t need to attach your relevant receipts to your tax return. However, if the tax office later requests for them, you will need to send them through. So, keep those documents ready because it’s hard to predict if they will be required or not.
You can use Taxfix to submit your tax return for four years retrospectively. As of today, you can submit tax returns from 2017.
Your data is always encrypted, whether it’s transmitted across Taxfix servers or to the tax office. We use the same encryption technology banks use for their online services and software. Besides, your data is forwarded to the tax office only if you explicitly permit us to do so.
Some perfectly legal tax tricks can help you get the most out of your tax. An example of this is the Commuting Allowance, which you can use to deduct commuting costs from your tax return. Few other places where you can save on taxes are:
  • Medical expenses
  • donations
  • pet sitters
  • cleaning costs for work clothes
  • advertising expenses
  • household-related services
Don’t worry! The Taxfix app is designed to address these points automatically to get maximum refunds.
Taxfix is a fintech start-up founded by Mathis Büchi and Lino Teuteberg in 2016. Taxfix enables people (who are clueless about taxes) to receive quick, easy and legal tax returns. Taxfix has been available in Germany since 2017 and has recent expansions in Italy and France.
