How we check our information

We write our guides and blog articles from primary sources: the German laws as published at gesetze-im-internet.de, official forms and announcements of the tax authorities.

Each page lists its sources at the end and shows when we last checked them.

When a law or a form changes, we update the text and the date.

Found a mistake? Write to support@portodoc.de and we will correct it.

Our texts are general information, not tax or legal advice. For your individual case, talk to a tax advisor.
