A flat in Valencia owned from Zurich needs Modelo 210 in Spain and a line in the Zurich tax return. The two use different values and different rules. dix.tax keeps them apart and gets both right.
We build the forms people ask for first. Tell us which one you need and we will write to you when it is ready.
Each percentage and form line comes from an official guide, law or directive, and every calculator lists its sources, including the one rule that rests on practice rather than on a directive.
Reference cases with known results run automatically on every change, so a fix in one place cannot quietly break another.
Your figures and addresses are calculated in your browser and never leave it. We only count anonymous events, such as which country a property is in.
dix.tax is built by Aleksej Dix in Zurich, who files these forms for his own properties.
I am Aleksej Dix. I file my taxes in Switzerland and own several flats abroad. The first time they had to go into my tax return, I paid for the answers myself: advisers, evenings with German directives, and a lot of second guessing.
The rules turned out to be simple once somebody explains them. Many people in Switzerland own a home in another country and face the same form, often in a language that is not their own. dix.tax puts what I learned into ten minutes.
