Our verdict

Wundertax suits German tax filers and small businesses who want a guided app rather than a full bookkeeping suite. It starts at €34.99 and runs on a free trial, so the entry point is higher than most of the field.

How wundertax compares

Frequently asked questions

How much does Wundertax cost?+

Wundertax charges from €34.99, and that starting figure is the number to plan around. A Free plan is rated no, so there is no free tier to fall back on. Access is offered on a free trial model, which lets you try the app before committing to a plan.

Is there a free trial?+

Yes. The model is a free trial, so a trial period comes before any payment. That suits readers who want to walk through a filing first. When the trial ends, the starting price is €34.99.

Is there a free plan?+

No. The Free plan is rated no, so Wundertax does not offer a permanent free tier. If you want to keep using the product at no cost, this is not the one. Trial access is available on a free trial basis, but the ongoing price starts at €34.99.

Who is Wundertax built for?+

The audience is beginners and small business, so it targets new filers and small businesses rather than large teams. Beginners and small-business users are both named in the audience. If you need enterprise features, a beginners and small business-focused product may not be the match.

Which platforms does Wundertax run on?+

The listed platform is ios, so the app is published for Apple devices. That makes it an easy fit for anyone already working in that ecosystem. Support is available on email and help centre if you need help while filing.

Where is the company based?+

Wundertax runs as wundertax GmbH, based in Germany. It was founded in 2015. A German home base suits a product shaped around national tax rules and local filings.

How do I get help?+

Support runs on email and help centre, which means email and a help centre. The help centre handles common questions without waiting for a reply. There is no phone line listed, so quick phone support is not part of the offer.

How does the price compare with similar tools?+

The starting price of €34.99 sits above the site median €13.15. Cheaper options include Qonto at €9 and Accountable at €9.90. If entry cost is the deciding factor, those are worth weighing first.
