Hitler Didn't Pay Income Taxes (in German)
I won't translate the whole article, but the gist is that, at the time he became chancellor in 1933, Hitler owed approximately 400,000 RM in back taxes. In December 1934, his delinquent tax bill was wiped out and his records were sealed ("unter Verschluss"). As the investigator who uncovered the Munich tax administration documents put it: "Hitler preached to the people that the common good goes before self-interest, but he himself acted otherwise" ("Hitler predigte dem Volk, Gemeinwohl gehe vor Eigennutz, und handelte selbst gegenteilig").
