Our verdict on wundertax
wundertax is an online German tax-return service for individuals handling a range of filing situations. It supports employees, self-employed people, students, expatriates, retirees and landlords, with options for individual, joint and property-tax returns. A question-based tax interview guides data entry, while tax tips and deduction guidance help users work through relevant sections. The service runs in a web browser and on iOS and Android, with cross-device continuation for returning to a filing from another device.
Published plans show one-time pricing by return type and package size. An individual return costs €34.99 for one return, €104.97 for three or €139.96 for four. Joint returns cost €49.99 for one, €149.97 for three or €199.96 for four. A property-tax return costs €49.99 for one return. The service supports preparation before payment and charges when returns are submitted, while electronic submission to the tax office is included in the listed return plans. The package structure suits taxpayers filing more than one return, while the single-return options fit occasional individual or joint filing.
Its strongest functional advantage is the combination of a live estimated-refund calculator, plausibility checking and electronic submission through the ELSTER interface. Support for self-employment, rental and investment income gives it a wider scope than a service focused only on standard employee returns. The trade-off is a narrow support channel: email is listed, with no 24/7 support. wundertax is a practical choice for German individuals or couples who want guided filing across devices and ELSTER submission. Taxpayers seeking state filing or broader support coverage should choose a different service.
