Skiing isn't the only reason German tourists come to the alpine village of Kleinwelsertal. Some of them bring their savings with them, because Kleinwelsertal is a tax haven. As far as customs law is concerned, it is part of Germany, so there is no border and no border controls. But the banking laws that apply here are Austria's. And bankers in Kleinwelsertal openly advertise that no one in Germany will ever learn about an account held here. But since German tax investigators began looking into people who evade German taxes by banking in Liechtenstein, Kleinwelsertal has been getting nervous.
