taxtastic is cloud-based software that lets you prepare your own income tax return and submit it directly to the tax office—no installation required, simply via your browser or the app.

The software guides you step by step through the process. The return is then submitted via the official ELSTER interface. Your data is stored in encrypted form on servers in Germany.

taxtastic is designed for anyone who wants to file their own tax return—without a tax advisor, without prior knowledge, and without spending hours on it.

The guided interview asks you simple questions about your personal situation and uses that information to create the tax return that’s right for you. You’ll only see the fields that are truly relevant to you—never a blank form, never a section that doesn’t apply to you.

taxtastic covers all common income situations: whether you’re an employee, retired, a freelancer, self-employed, or a combination of these. Wages, investment income, rental income, and simplified accounting (EÜR)—individually or combined in a single return. An automatic validity check ensures that your information is consistent before everything is submitted directly to the tax office via ELSTER.

No. taxtastic is software—it does not provide tax advice in the legal sense. The information provided is of a general nature and does not replace individual advice. You are personally responsible for the accuracy of your information.

taxtastic is available exclusively in German and is intended for individuals subject to taxation in Germany.

All prices are final and include sales tax—no hidden costs.

No. taxtastic is a one-time purchase with no subscription or automatic renewal. You pay once for a tax year and will never be automatically charged. For subsequent tax years, you simply purchase a new license.

No. If spouses or registered partners file a joint tax return, one package is sufficient.

Yes, the Basic Package supports tax years starting in 2015. You’ll need a separate package for each tax year. How far back you can file depends on the deadline: four years for voluntary filings, and up to seven years if filing is required.

You. taxtastic checks your entries for plausibility but cannot perform a comprehensive review of the content. The responsibility for providing accurate and complete information lies with you.

We are not liable for additional tax payments or lost refunds resulting from incorrect information.

Access remains active until the return is submitted to the tax office—or until the end of the year following the tax year, whichever comes later.

After these periods expire, all data is automatically deleted.

ELSTER (ELektronische STeuerERklärung) is the official transmission procedure of the German tax administration. taxtastic uses exclusively this certified interface—all data is transmitted with end-to-end encryption (SSL/TLS).

No. taxtastic handles the ELSTER submission for you—you don’t need your own account.

That depends entirely on the tax office in charge and is beyond taxtastic’s control. Experience shows that electronic submissions are processed faster than those sent by mail.
