Zasta: Super-App für Steuern

Zasta GmbH

About this app

Thanks to Zasta, you'll never have to do your tax return yourself again. From now on, let experts handle your tax return for 2022–2025—specifically, a real tax advisor.

The Zasta principle for your 2025 tax return is super simple:

+++ Register in 3 minutes and receive an average of over €1,000 +++
Registering for Zasta is free and easy. All you need is your name, address, and tax ID number from your payslip. Zasta can then automatically retrieve existing data from the tax office* and prepare your tax return for you. Unique in Germany.

+++ Free refund calculation +++
You'll receive a free quote from our partner tax advisors as soon as possible, listing your potential refund, including the fees for filing your income tax return, because transparency is our top priority. You can then simply accept the quote and further increase your refund for your 2022–2025 tax return by specifying any additional expenses you incurred.


+++ Free refund calculation +++ +++ Real tax advisors work for you +++
Not familiar with taxes? Missed the tax return deadline? What can you claim on your income tax return and what can't you? All of that is no longer a problem, because real experts will prepare your tax return for you.

Zasta has developed the tax app in collaboration with tax advisors. If you accept the free offer, the tax advisors will check whether you can claim expenses for commuting costs (commuter allowance), the home office allowance, further training costs, work clothes costs, childcare costs, and much more on your tax return. This way, you can get even more tax back. Filing an income tax return couldn't be easier.

+++ Get tax refunds retroactively for 4 years +++ Haven't filed a tax return yet? No problem, with Zasta you can also get tax refunds for previous years. For the last four years, this averages over €4,000.

Filing your tax return in 2026 is still possible for the following years:

Tax return 2025
Tax return 2024
Tax return 2023
Tax return 2022
