We use data leaked from the Isle of Man to understand how well international agreements meant to provide tax authorities with info on foreign accounts actually work
We find that tax authorities probably receive a lot less than they would desire

After Trump´s disgraceful behavior last week, we thought we need to do something to help Ukraine directly. And you can help too…
If one person gives a euro to Ukraine, the result is €1.
If two people give 2 each, it is €4.
If 3,000 give 3,000 each, it is 9 million.
Let’s coordinate, here 👇

Abseits des offiziellen Parteiprogramms fällt die FDP-Führung gerne mal durch verbale Ausrutscher auf. Welches Klientel soll da eigentlich angesprochen werden, fragt unser Gastautor Paul Hünermund.
