A team of researchers has combined disclosures from the Panama Papers with administrative tax data and population records in Scandinavia and finds that “tax evasion rises sharply with wealth.” The rich do this primarily by parking wealth in Switzerland and other tax havens. I don’t think this comes as a surprise to anyone, but the size of the tax evasion might:
Of course, this is just for those infamous scofflaws in Denmark, Sweden, and Norway. American zillionaires are probably a lot more honest, don’t you think?
POSTSCRIPT: Snark aside, personal tax rates are pretty high in Scandinavia—though not as high as urban legend has it. Still, their high rates do provide a bigger incentive to hide wealth overseas, so it’s possible that American tax evasion is lower than it is in Scandinavia. I wouldn’t bet on it, though.
