What we do for you

Steuererstattung in ganz Europa

Als ausländische Arbeitskraft sollten Sie auch in Ihrem Gastland Ihre Steuern erklären. Sonst schenken Sie womöglich den Finanz­behörden Ihres Gastlands Jahr für Jahr hunderte oder gar tau­sende Euro. UnionTAX hilft Ihnen dabei, Ihre Steuer­erklärungen in ganz Europa einfach und problemlos zu erledigen!

Kinder­geld­erstat­tung im EU-Ausland

Wenn Sie in den vergangenen Jahren im EU-Ausland gearbeitet haben oder arbeiten, haben Sie, unab­hängig davon, wo Ihre Kinder leben, auch Anspruch auf Kinder­geld im Gastland – teilweise bis zu fünf Jahre rück­wirkend. Und mit UnionTAX wird die Bean­tragung Ihrer Ansprüche europaweit zum Kinderspiel.

Entschädigung bei Flugverspätung

Flugverspätungen gehören bei Fluggesellschaften inzwischen zum Alltag. Auch deshalb hat die EU dieser Praxis der Flug­gesell­schaften einen Riegel vorgeschoben – beanspruchen Sie mit UnionTAX bis zu 600 € Entschädigung, wenn sich Ihr Flug mal wieder verspätet.

Legal representation

Bringing together tax experts and attorneys, we support our clients in enforcing their legal claims and representing them before family benefits offices, tax authorities, social courts, and fiscal courts.

Tax translations

Transparent, understandable and comprehensible – that's what the ideal tax return should look like to be accepted and approved by the tax office. Especially when you're operating abroad, the topic of "taxes" can become an insurmountable language problem.

Take advantage of Europe's market leader

„UnionTAX - Experts on Europe-wide tax translations, tax refunds and social benefits payments“

UnionTAX  Your partner in Europe for tax refunds and child benefits applications.
